[Overview of Application Control Information (AIT)]
The application control information (AIT) of the present embodiment is transmitted to an application (a broadcast receiver 100 in the present embodiment) that cooperates with a broadcast service in a broadcast communication cooperation function supported by the broadcast receiver 100. Hereinafter, it may be referred to as a broadcast cooperation application.) It is assumed that the information is intended to inform the user of the existence of the broadcast cooperation application and to instruct the control thereof. The broadcast cooperative app operates only in a broadcast receiving state based on (1) a control signal such as start / end included in a broadcast signal, and is a broadcast managed application that is permitted to access a broadcast resource based on the control signal. An application, (2) a non-broadcast managed application that is permitted to access a broadcast resource based on means such as application authentication in an operation mode in which start / end is not controlled by a broadcast signal, and (3) a broadcast resource It may be distinguished from other general applications to which access is not permitted.

  The AIT transmission method includes a method of transmitting a section format or an extensible markup language (XML) AIT in a broadcast wave by a data carousel (DC) method or the like, and a method of transmitting the section format or the XML format AIT file to the Internet. Any method may be used in which data is distributed from the server device on the Internet 200 using http (Hypertext Transfer Protocol) or https (Hypertext Transfer Protocol Secure). Other methods may be adopted.

  FIG. 6 is a data configuration diagram illustrating an example of the data configuration of the AIT. The AIT mainly includes an application type 901, an application identifier 902, an application control code 903, an application profile 904, an application acquisition destination information 905, an application boundary and access authority setting 906, a startup priority 907, a cache information 908, and a server access distribution parameter 909. , Etc. Further, other information may be included.

  The application type 901 defines a description method of an application. In this embodiment, the description method of the application is assumed to be HTML. The application identifier 902 is identification information composed of an organization identification for identifying a business entity and an application identification numbered for each business entity for identifying an application unit. Note that the application unit is a set of an HTML document and its reference resources in which the HTML document existing at the location specified by the application acquisition destination information 905 is an entry document. The application control code 903 defines operation control for a target application, and describes one of (1) automatic start, (2) operable, (3) end, and (4) prefetch. . The application profile 904 is a value indicating a function of the television receiver requested by the application, and indicates a combination of functions that the television receiver has as options. The availability of the application is determined by referring to this value.

  The application acquisition destination information 905 is information for specifying the acquisition destination of the application, and is location information for acquiring an HTML document to be referred first when the application is activated. Since it is assumed that the application is transmitted by broadcasting and that the application is placed on a server device on a communication network, the location information specified by the application acquisition destination information 905 also corresponds to both the broadcast acquisition and the communication acquisition. Provisions are made. The application boundary and access restriction setting 906 is information indicating an operable range as a broadcast managed application as a set of one or more areas (URL: Uniform Resource Locator). In addition, access restriction to the broadcast resource for each area is set for each function. The application boundary and the access restriction setting 906 specify a range of document transition for preventing transition to an unexpected document or access to an inappropriate broadcast resource due to a chain of document transitions from an entry document at application startup. I do. In addition, it is possible to set an access right to a specific broadcast resource in a region unit within the range of the document transition.

  The activation priority 907 defines which one is activated first when a data broadcast by a broadcast service and a broadcast managed application by an HTML document exist simultaneously. Unconditionally designating data broadcasting as the highest priority on the PMT, designating the activation priority of a specific application type on the PMT, and designating the activation priority of the target application with the activation priority 907; Is possible. The cache information 908 is information used for cache control when an application resource is held in preparation for reuse of an application. With this information, it is possible to cache the application resources assuming reuse even after the application is terminated. The server access distribution parameter 909 is a parameter set for distributing the access for the purpose of reducing the load on the server where the access is concentrated at the acquisition destination of the application. The television receiver may operate to stochastically delay application of the application control code according to the setting of this parameter.

  Hereinafter, an operation of the broadcast receiving apparatus 100 according to the present embodiment will be described.

[Operation sequence at application startup]
First, a description will be given of a process of activating a broadcast cooperative app based on an AIT transmitted by a broadcast wave in the broadcast receiving apparatus 100 of the present embodiment. In the broadcast receiving apparatus 100 according to the present embodiment, the information on the PMT and the information such as the application control code 903 of the AIT and the activation priority 907 give priority to either of the data broadcasting by the broadcast service and the broadcast cooperative app when they exist simultaneously. Can be specified.

  FIG. 7A is an operation sequence diagram illustrating an example of an operation sequence of the broadcast cooperative application in a case where the broadcast cooperative application is defined to be activated with priority. FIG. 5 shows a series of flows from when the broadcast receiving apparatus 100 appropriately checks the PMT and the AIT and starts a predetermined broadcast cooperation application.

  When the tuner / demodulation unit 131 of the broadcast receiving apparatus 100 performs channel selection processing of a channel desired by the user to obtain a TS, the main control unit 101 obtains a PMT data sequence separated by the first separation unit 132. (S101), the activation priority described in the PMT is confirmed. When it is confirmed in the process of S101 that the start priority of the broadcast cooperative application is high (S102), the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S103), and the acquired AIT The application control code 903 in the data string is confirmed (S104). If the application control code 903 is “automatic start” in the processing of S104, the application profile 904 of the acquired AIT data sequence is further confirmed (S105), and the execution of the broadcast cooperative application specified in the AIT is started. If it is confirmed that transmission is possible, a transmission request of the broadcast cooperation application is transmitted to a predetermined service provider server 400 via the LAN communication unit 121 based on the information described in the application acquisition destination information 905. (S106).

  The service provider server 400 that has received the transmission request for the broadcast cooperative app performs authentication processing of the broadcast receiving apparatus 100 as necessary under the control of the application management / distribution execution unit 4103, and then stores the authentication information in the application storage area 4013. The stored predetermined broadcast cooperation application is delivered via the LAN communication unit 421 (S107). A known method may be used for the authentication process, and a detailed description thereof will be omitted. Next, the application engine 162 of the broadcast receiving apparatus 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400 and received via the LAN communication unit 121 under the control of the application control unit 161. (S108).

  FIG. 7B is an operation sequence diagram showing an example of an operation sequence of the broadcast cooperative app in a case where it is defined that data broadcast by the broadcast service is started with priority. FIG. 5 shows a series of flows from when the broadcast receiving apparatus 100 appropriately checks the PMT and the AIT and starts a predetermined broadcast cooperation application.

  When the tuner / demodulation unit 131 of the broadcast receiving apparatus 100 performs channel selection processing of a channel desired by the user to obtain a TS, the main control unit 101 obtains a PMT data sequence separated by the first separation unit 132. (S201), the activation priority described in the PMT is confirmed. When it is confirmed in the process of S201 that the activation priority of the data broadcast by the broadcast service is high (S202), the data broadcast reception processing unit 141 acquires the BML data sequence separated by the first separation unit 132 and converts the BML document into a BML document. Playback is performed (S203). When the automatic start of the data broadcast is set by the BML document, and when the user makes a start request of the data broadcast using the operation terminal (the portable information terminal 700, a remote controller, etc.) (S204), the data broadcast engine 142 Generates the data broadcast screen information by executing the reproduced BML document and displays it on the video display unit 173 (S205).

  After the processing of S205 or simultaneously with the processing of S205, the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S206), and checks the application profile 904 of the acquired AIT data string. (S207). In the process of S207, when it is confirmed that the broadcast cooperative application specified in the AIT can be executed, an entry button to the executable broadcast cooperative application is displayed on the data broadcast screen. The entry button may be displayed at all times, and the color scheme may be changed from an inactive color to an active color only when the broadcast cooperative app can be executed. By changing the shape, the entry button may be switched between an inactive state and an active state.

  When the user selects the entry button using the operation terminal (S208), the data broadcast engine 142 ends the process of executing the BML document and generating the data broadcast screen information (S209). Subsequently, the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S210), and checks the application acquisition destination information 905 of the acquired AIT data string. Further, based on the information described in the application acquisition destination information 905 confirmed in S210, a transmission request for a broadcast cooperative application is transmitted to a predetermined service provider server 400 via the LAN communication unit 121 (S211).

  The service provider server 400 that has received the transmission request for the broadcast cooperative app performs authentication processing of the broadcast receiving apparatus 100 as necessary under the control of the application management / distribution execution unit 4103, and then stores the authentication information in the application storage area 4013. The stored predetermined broadcast cooperation application is distributed via the LAN communication unit 421 (S212). Next, the application engine 162 of the broadcast receiving apparatus 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400 and received via the LAN communication unit 121 under the control of the application control unit 161. (S213).

  FIG. 7C is an operation sequence diagram illustrating an example of an operation sequence of the broadcast cooperative application in a case where no priority activation is specified. FIG. 5 shows a series of flows from when the broadcast receiving apparatus 100 appropriately checks the PMT and the AIT and starts a predetermined broadcast cooperation application.

  When the tuner / demodulation unit 131 of the broadcast receiving apparatus 100 performs channel selection processing of a channel desired by the user to obtain a TS, the main control unit 101 obtains a PMT data sequence separated by the first separation unit 132. (S301), the activation priority described in the PMT is confirmed. When it is confirmed in the processing of S301 that the start priority of the broadcast cooperation application is high (S302), the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S303), and acquires the acquired AIT data string. The application control code 903 in the data string is confirmed (S304). If the application control code 903 is “auto startable” instead of “auto start” in the process of S304, the display of the broadcast program is continued without starting any of the data broadcasting by the broadcast service and the broadcast cooperative app.

  When the user issues a data broadcast activation request using the operation terminal after the processing of S304 is completed (S305), the acquisition of the BML data sequence and the BML are performed in the same manner as the processing from S205 onward in FIG. 7B. Playback of a document, generation of data broadcast screen information, and the like are performed (however, not shown). On the other hand, when the user makes a request to start the broadcast cooperative app launcher using the operation terminal after the processing of S304 is completed (S306), the application control unit 161 separates the AIT data separated by the first separation unit 132. A column is acquired (S307), and the application profile 904 of the acquired AIT data column is confirmed (S308). Further, the application control unit 161 displays a list of executable broadcast cooperative apps on the video display unit 173 as a broadcast cooperative app launcher (S309).

  When the user uses the operation terminal to select a predetermined broadcast cooperative app from the broadcast cooperative app launcher displayed in S309 (S310), the application control unit 161 converts the AIT data string separated by the first separation unit 132. Acquisition (S311), the application acquisition destination information 905 of the acquired AIT data string is confirmed. Further, based on the information described in the application acquisition destination information 905 confirmed in S311, the transmission request of the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 (S312).

  The service provider server 400 that has received the transmission request for the broadcast cooperative app performs authentication processing of the broadcast receiving apparatus 100 as necessary under the control of the application management / distribution execution unit 4103, and then stores the authentication information in the application storage area 4013. The distribution of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S313). Next, the application engine 162 of the broadcast receiving apparatus 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400 and received via the LAN communication unit 121 under the control of the application control unit 161. (S314).

  Note that, in the activation sequence of the broadcast cooperation application described with reference to FIGS. 7A to 7C, an example in which the AIT is acquired from a broadcast wave is described, but a predetermined server device specified by an information description of the PMT or the like is described. The AIT file may be acquired from. Further, the acquisition of the broadcast cooperation application may be performed not from the server device (the service provider server 400) on the network but from the broadcast wave. That is, when the location information described in the application acquisition destination information 905 of the AIT indicates a broadcast wave, the application control unit 161 transmits the HTML data string separated by the first separation unit 132 and transmitted by the data carousel method or the like. , An HTML document may be reproduced, and the reproduced HTML document (broadcast cooperation application) may be executed by the application engine 162.

  If there is no information on the PMT specifying the start priority when the data broadcasting by the broadcast service and the broadcast cooperative app are present at the same time, the start is performed only by the information such as the AIT application control code 903 and the start priority 907. You may confirm a priority. Similarly, when the acquisition of the information on the PMT fails, the activation priority may be confirmed only by the information such as the application control code 903 of the AIT and the activation priority 907. In other words, the AIT is periodically checked regardless of the information on the PMT, and if a broadcast cooperative application designated by “automatic start” exists in the application control code 903 of the AIT, the broadcast cooperative application In the case where there is no broadcast cooperative application designated by the “automatic start” in the application control code 903 of the AIT, the start of data broadcasting by the broadcast service may be prioritized.

  If a response from the service provider server 400 has not been received for a predetermined time or longer when a distribution request for a broadcast cooperative app is made in S106, S211, or S312, a message such as "Please wait" is displayed on the video display unit 173. It may be displayed. Alternatively, in this case, a message for inquiring the user to stop the execution of the broadcast cooperative app may be displayed.

  In addition, the start sequence of the broadcast cooperative application is not limited to the above-described three patterns, and it goes without saying that the start sequence may be started by a different sequence.

[Operation sequence when linking portable information terminals]
In the broadcast receiving device 100 of the present embodiment, it is assumed that the function of the broadcast communication cooperative service can be extended by the cooperative operation between the broadcast receiving device 100 and the portable information terminal 700.

An error code and a guide (URL or the like) of a homepage of the television receiver maker in which the description of the error code is described may be displayed. Alternatively, when the broadcast cooperative app is acquired from the network, the network connection status is naturally checked in advance. At this time, for example, the acquisition of the broadcast cooperative app is not performed due to insufficient LAN cable connection or the like. If it is not possible, that fact is displayed in the error message 173d1. The error message 173d1 may also be displayed when the network connection has been established, but the broadcast cooperative app cannot be correctly acquired due to the poor error situation. The error message 173d1 may be displayed when the acquisition of the broadcast cooperation application is being executed and the execution of the broadcast cooperation application is not yet performed. Also, the error message 173d1 is displayed when the reception status of the broadcast wave is not stable and the information such as the AIT cannot be received in the middle of the process although the information such as the AIT can be received at first. good. In such a case, if the broadcast cooperative application acquired from each server device is cached as it is, it can be used as it is after the reception status of the broadcast wave is recovered.

  Also, as a result of the confirmation of the application profile 904, when the predetermined optional function is insufficient on the television receiver side, an error message 173d1 is displayed indicating that the confirmation or update of the latest television receiver firmware is recommended. You may do it. Alternatively, the broadcast receiving apparatus 100 may automatically check or update the latest firmware. Alternatively, if the broadcast cooperative app can be executed by adding a paid optional hardware or optional software to the television receiver, the guidance of the paid optional hardware or the optional software may be displayed. good. The error message 173d1 may be displayed not on the broadcast receiving device 100 but on the portable information terminal 700.

[Execution screen of the broadcast cooperative application of the portable information terminal]
FIG. 15 is a screen display diagram showing an example of the broadcast cooperative app (terminal side) execution screen displayed in the processing of S619 in FIG. The broadcast cooperation application execution screen 741c shown in FIG. 15 includes a main window 741c1, a sub window 741c2, a selection marker 741c3, cursor keys 741c4 and 741c5, a comment display section 741c6, and an end button 741c7. Other objects may be further added.

  In the present embodiment, it is assumed that the broadcast cooperation application (terminal side) executed on the portable information terminal 700 is an application for confirming details of a broadcast program being displayed on the broadcast receiving device 100.

The end button 741c7 is a button for ending the operation of the broadcast cooperation application (terminal side).

  By operating the broadcast cooperative app (terminal side) on the portable information terminal 700, the function of the broadcast communication cooperative service can be extended by the cooperative operation between the broadcast receiving device 100 and the portable information terminal 700.

[EPG screen of broadcast receiver]
FIG. 16A is a screen display diagram illustrating an example of an electronic program guide (EPG) display screen in the broadcast receiving device 100 according to the present embodiment. The EPG display screen 173e is a distribution schedule of a broadcast program in the digital broadcast service of the present embodiment created by the main control unit 101 based on the program information data string output from the first separation unit 132. It is assumed that the EPG display screen 173e is displayed on the video display unit 173 by selecting the program table key 741a7 on the basic screen 741a of the cooperation control application.

  In the present embodiment, the EPG display screen 173e has a matrix shape in which the vertical axis indicates time and the horizontal axis indicates service ID (channel), and displays detailed information of each broadcast program broadcast on each channel in each time zone. indicate. As shown in FIG. 16A, the detailed information 173e1 of each broadcast program mainly includes a title area 173e2 and a detailed explanation area 173e3.

  The title area 173e2 displays a program title of each broadcast program, a symbol indicating an attribute of each broadcast program, and the like. The symbols and the like representing the attributes of the respective broadcast programs are, for example, a sign obtained by symbolizing “New” indicating a new program, a mark obtained by encoding “Replay” indicating a rebroadcast program, And so on. Alternatively, it may be a mark obtained by encoding “data”, which means that data broadcasting by a broadcasting service is supported. Further, in the case of a broadcast program in which a broadcast cooperative application executable by the broadcast receiving apparatus 100 of the present embodiment is prepared, a mark obtained by symbolizing “Linkage” indicating that fact may be used. The detailed description area 173e3 displays related information such as the program contents and performers of each broadcast program, the URL of a homepage introducing each broadcast program, and the like.

  In addition, even if the broadcast program is provided with a broadcast cooperative application, the mark or the like that is displayed in the title area 173e2 by symbolizing the “Linkage” is displayed as a result of the confirmation of the application profile 904 and the information display device. If the execution at 100 is not possible, it may not be displayed. In addition, the symbol “Linkage”, which is displayed in the title area 173e2 and indicates that the broadcast program is provided with the executable broadcast cooperative app, can be further cooperated with the portable terminal device. , The color, shape, font, etc. may be changed. When the cooperative operation with the portable terminal device is possible, a mark obtained by symbolizing “Mobile” may be displayed together with a mark obtained by coding “Linkage”.

  It should be noted that the presence or absence of the display of the symbol “Linkage” or the symbol “Mobile” is determined in advance by the EIT information including detailed information of each broadcast program. Whether or not the broadcast program is a broadcast program for which a broadcast cooperative application executable by the broadcast receiving apparatus 100 of the embodiment is prepared, and whether the executable broadcast cooperative application can cooperate with a mobile terminal device, It may be controlled by acquiring information such as Alternatively, the information obtained from the program distribution information of the digital broadcast program prepared in a predetermined server device on the Internet 200 is stored in an electronic program table created based on the program information data sequence obtained from the broadcast wave of the digital broadcast service. It may be added.

  As described above, on the EPG display screen 173e, it is possible to perform a symbolic mark of "Linkage" indicating that the program is a broadcast program for which an executable broadcast cooperative application is prepared, or to cooperate with a portable terminal device. Is displayed, the user can easily grasp the support status of each broadcast program in the broadcast receiving apparatus 100 for the broadcast communication cooperation service. Needless to say, the mark in which the predetermined character representing the attribute of each broadcast program is symbolized may be replaced with the character itself, a sentence, or the like. By changing the background color of the detailed information 173e1 of each broadcast program, the support status of each broadcast program to the broadcast communication cooperation service may be indicated. In addition, a mark obtained by symbolizing “Linkage” or a mark obtained by symbolizing “Mobile” is not normally displayed in the title area 173e2, and pops up only when each broadcast program is selected by the program selection cursor 173e4. It may be displayed.

  The broadcast receiving apparatus 100 of the present embodiment has a function of making a viewing reservation and / or a recording reservation for each broadcast program from the EPG display screen 173e. For example, while the EPG display screen 173e is displayed, the program selection cursor 173e4 on the EPG display screen 173e is moved using the cursor keys 741ac on the basic screen 741a of the cooperative control application, and an arbitrary broadcast program is set using the enter key 741ad. Is selected, a viewing reservation and / or a recording reservation of the selected broadcast program are made.

  In the above-described processing, if the broadcast program for which the viewing reservation and / or recording reservation has been made is a broadcast program corresponding to a broadcast communication cooperation service, the execution of the viewing reservation and / or recording reservation is triggered by the broadcast. The acquisition of the broadcast cooperative application prepared for the broadcast program may be started without waiting for the broadcast start time of the program. That is, information (location information such as a URL) for specifying the acquisition destination of the broadcast cooperation application is described in the EIT information including detailed information of each broadcast program. By doing so, the broadcast receiving apparatus 100 can grasp the information on the acquisition destination of the broadcast cooperation application prepared for each broadcast program at the time when the broadcast program is selected by the program selection cursor 173e4. Become. Therefore, the broadcast receiving apparatus 100 can start acquiring the broadcast cooperation application before the broadcast start time of the broadcast program.

  If the broadcast program for which the viewing reservation and / or the recording reservation has been made is a broadcast program corresponding to a broadcast / communication cooperation service and is a broadcast program that can cooperate with a portable terminal device, The broadcast cooperative app (terminal side) prepared in the above may also be started to acquire before the broadcast start time of the broadcast program by the same processing as described above. Further, as shown in FIG. 16B, a two-dimensional barcode 173e5 or the like indicating information (location information such as URL) of an acquisition destination of the broadcast cooperation application (terminal side) prepared for the portable terminal device is displayed on the EPG display screen 173e. May be displayed to prompt the user to download the broadcast cooperative app (terminal side) prepared for the mobile terminal device.

  As described above, if the broadcast receiving apparatus 100 starts acquiring the broadcast cooperative application before the broadcast start time of the broadcast program with reference to the acquisition destination information of the broadcast cooperative app included in the EPG information, Thus, the load on the service provider server 400 that stores the broadcast cooperation application can be dispersed. Further, even if the communication speed of the network between the service provider server 400 and the information display terminal 100 is insufficient, the broadcast cooperative app can be effectively used immediately after the start of the broadcast of the broadcast program. become.

  FIG. 17 is an operation sequence diagram showing an example of an acquisition sequence of a broadcast cooperative application when a viewing reservation and / or a recording reservation of a broadcast program are made on the EPG display screen 173e.

  During viewing of the digital broadcast service, the main control unit 101 of the broadcast receiving apparatus 100 acquires the program information data string output from the first separation unit 132 (S701). When the user issues an EPG screen activation request using the operation terminal (S702), an EPG display screen 173e is displayed on the video display unit 173 (S703). When the user makes a viewing reservation and / or a recording reservation of the broadcast program by selecting an arbitrary broadcast program using the operation terminal on the EPG display screen 173e (S704), the main control unit 101 performs the first separation. The program information data string acquired from the unit 132 is confirmed (S705), and the location of the acquisition destination of the broadcast cooperative application linked to the broadcast program for which the viewing reservation and / or the recording reservation has been made is confirmed (S706).

  After the processing of S706, the application control unit 161 transmits a transmission request of the broadcast cooperation application to a predetermined service provider server 400 via the LAN communication unit 121 based on the confirmed URL (S707). The service provider server 400 that has received the transmission request for the broadcast cooperative app performs authentication processing of the broadcast receiving apparatus 100 as necessary under the control of the application management / distribution execution unit 4103, and then stores the authentication information in the application storage area 4013. The stored predetermined broadcast cooperation application is delivered via the LAN communication unit 421 (S708). Subsequently, the application control unit 161 caches the predetermined broadcast cooperation application received from the service provider server 400 and received via the LAN communication unit 121 in the RAM 104 or the storage 110 (S709).

  According to the transmission / reception device 100 of the present embodiment described above, it is possible to execute a function with higher added value.

  Hereinafter, a second embodiment of the present invention will be described. The configuration, effects, and the like in this embodiment are the same as those in the first embodiment unless otherwise specified. Therefore, in the following, differences between the present embodiment and the first embodiment will be mainly described, and description of common points will be omitted as much as possible to avoid duplication.

  Although the embodiment in which the portable information terminal cooperation process (hereinafter, referred to as terminal cooperation) is performed has been described in the first embodiment, a more detailed embodiment will be described.

  When performing the portable information terminal cooperation, there is a case where it is desired to restrict the use of the terminal cooperation to only the portable information terminal 700 located in the same house as the broadcast receiving apparatus 100 (hereinafter, this restriction is referred to as the same house restriction). For example, in an application for using broadcast cooperation (hereinafter referred to as a broadcast cooperation application), the case where the display screen of the broadcast receiving apparatus 100 and the display screen of the portable information terminal 700 are closely related, This is a case where the user of the portable information terminal 700 wants to surely view the displayed advertisement video.

  The point to be considered as a procedure is to determine whether or not the target broadcast cooperation application imposes the same in-house restriction. This determination is unnecessary when it is assumed that all the broadcast cooperative apps have the same in-house restriction. However, when there is no restriction in some cases, the control information on the presence or absence of the same in-house restriction is transmitted to the broadcast receiving apparatus 100. Need to get and change the operating procedure. The control information on the presence or absence of the restriction may be obtained from a broadcast signal (for example, described as an AIT item) or may be obtained from a server designated by a broadcast station.

  In the present embodiment, including the above procedure, a procedure for guaranteeing that the portable information terminal 700 exists in the same house as the broadcast receiving apparatus 100 will be described.

  Usually, devices existing in the same house exist on a local network connected to the same router device 210. Therefore, since the portable information terminal 700 is connected to the same local network as the broadcast receiving device 100, it can be determined that the portable information terminal 700 exists in the same house. A known method may be used to determine whether the target device is connected to the local network, and a description thereof will be omitted.

  Further, even if the portable information terminal 700 is not on the local network, it can be determined that the portable information terminal 700 is located in the same house by directly communicating with the broadcast receiving device 100 by NFC, BlueTooth, infrared communication, or the like. In this case, the communication for acquiring the broadcast cooperative app or the like may be the above-described direct communication or mobile communication.

  As described above, there are a plurality of methods for confirming that the user is in the same house, but which method is used is described in, for example, the AIT, and is read by the broadcast receiving apparatus 100.

  Further, once it is confirmed that the portable information terminal 700 exists in the same house, it may be considered that the portable information terminal 700 exists in the same house until the end of the program, or a certain valid time (for example, 10 minutes) is provided and May be regarded as existing in the same house, but if the validity time has passed, a method may be used in which it is not assumed that the object is present in the same house unless a new confirmation is made. The valid time is described in the AIT, for example, and read by the broadcast receiving apparatus 100.

  Furthermore, for example, an event signal is set in a broadcast signal at an arbitrary point during the progress of a program, and every time the event signal is received, it is confirmed that the portable information terminal 700 exists in the same house. Can also.

  Further, the former two methods can be used in combination.

  Next, a specific procedure for permitting terminal cooperation only to the portable information terminal 700 existing in the same house will be described. In this embodiment, restrictions are provided when the portable information terminal 700 acquires a broadcast cooperative app or information used by the broadcast cooperative app (hereinafter, the broadcast cooperative app and information used by the broadcast cooperative app, Typically, it is an HTML document or a streaming video, but these are collectively referred to as broadcast cooperation information.) There are two types of methods for acquiring the broadcast cooperation information: communication acquisition obtained from the broadcast station server 300 or the business server 400 and broadcast acquisition obtained from broadcast waves. In the case of communication acquisition, there are two types, a method of acquiring after the start of broadcast reception and a method of acquiring before the start of broadcast reception. Furthermore, in the case of communication acquisition, the case where the broadcast receiving device 100 acquires once, and the portable information terminal 700 acquires from the broadcast receiving device 100, and the case where the portable information terminal 700 acquires directly from the broadcast station server 300 or the business server 400 There is. Although there are various methods, when viewed from the portable information terminal 700, it can be broadly classified into two cases: obtaining from the broadcast receiving device 100 and obtaining from the broadcast station server 300 or the business server 400.

  In this embodiment, the case where the portable information terminal 700 acquires the broadcast cooperation information from the broadcast receiving device 100 will be described, and the case where the portable information terminal 700 acquires the broadcast cooperation information from the server will be described in the next embodiment.

  FIG. 18A shows the procedure of this embodiment.

  First, before performing the terminal cooperation, each of the portable information terminal 700 and the broadcast receiving device 100 starts a cooperation control application that is an application for controlling the terminal cooperation (S10001 and S10002). In this state, the portable information terminal 700 issues a terminal cooperation request to the broadcast receiving device 100 (S10003). Next, the AIT is obtained from the broadcast signal (S10004). Based on the information of the AIT, it is determined whether or not the target mobile information terminal application has the same in-house restriction (S10006). If there is a restriction, the procedure proceeds to S10008, and the first stage in which the terminal cooperation request is made Then, the process proceeds to step S10009, and it is determined whether or not the portable information terminal 700 that has requested the terminal cooperation is located in the same house as the broadcast receiver 100 (S10009). As a result of the determination, if it is determined that the mobile information terminal is not located in the same house, a response indicating that the cooperation is not permitted is sent to the cooperation control application on the portable information terminal side, and the process ends (S10011).

  Here, if it is assumed that all the broadcast cooperation applications have the same in-house restriction, the determination in S10006 is skipped without being performed. If there is both an application with the same home restriction and an application without the same home restriction, the determination of S10006 is made.

  If it is determined that the portable information terminal 700 is located in the same house or if the application does not have the same house restriction, the process advances to step S10012 to perform a broadcast cooperative application related service. This service (S10012) processes the broadcast cooperative information distribution request (S10013) from the portable information terminal 700, and distributes the broadcast cooperative information to the portable information terminal 700 (S10018). The broadcast cooperation information includes the information received by the broadcast receiving apparatus 100 from the distribution server as the business server 300 (S10014, S10015, S10016), the information obtained from the broadcast signal (S10017), and the broadcast receiving information stored in the broadcast receiving apparatus 100. There are things that are done. The reception of the broadcast cooperative information by the broadcast receiving device 100 (S10016, S10017) is not limited to the case of the broadcast cooperative information distribution request (S10013) from the portable information terminal 700, and the broadcast receiving device 100 can obtain the autonomous information, The acquisition may be based on the occurrence of an event from a broadcast signal. The distribution of the broadcast cooperation information to the portable information terminal 700 (S10018) may be voluntary from the broadcast receiving device 100 side.

  After the process of receiving (acquiring) and distributing the series of broadcast cooperation information is completed, it is determined whether or not the broadcast receiving apparatus 100 continues to view the same program (S10019). A response indicating that the cooperation is not permitted is sent to the cooperation control application, and the process ends (S10020).

  If the viewing is continued, the procedure returns to S10005, and if there is a house restriction, whether or not the portable information terminal 700 is in the same house is checked (S10009). However, the preset effective time has elapsed since the previous check. It is determined whether or not a confirmation request (S10007) has been issued from a broadcast signal or a distribution server since the previous confirmation (S10008). If neither condition is satisfied, it is determined whether or not the user is in the same house. The confirmation (S10009) is not performed, and the process proceeds to the next broadcast cooperative application related service (S10012) via S10010. Here, the confirmation request (S10007) from the broadcast signal is described as being acquired from the broadcast cooperation information. Here, the event message is also described as being included in the broadcast cooperation information. Further, this confirmation request may be described in the AIT.

  The procedure described above is a loop processing procedure for the broadcast signal, the broadcast receiving device 100, the portable information terminal 700, and the entire distribution server in the section indicated by the arrow in S10022. The confirmation request in S10007 may be at any timing in the loop.

  Further, the authentication information described in the AIT may be incorporated in an authentication key used for authentication at the distribution server (S10015). Thereby, it can be confirmed that the request is a valid authentication request. If the authentication information described in the AIT is changed with the progress of the program, and if the distribution server does not perform authentication unless the authentication key incorporates information synchronized with the progress of the program, the same program can be used. You can confirm that you continue to watch. In this case, the information of the AIT is appropriately read and updated (S10021). Note that the authentication information to be incorporated in the broadcast signal may be incorporated as broadcast cooperation information in addition to being described in the AIT. Further, as a method of substantially changing the authentication information, a method of changing the URL itself of the distribution server in accordance with the progress of the program can be used.

  As described above, while the broadcast cooperative app-related service (S10012) is being executed, the portable information terminal 700 receives the broadcast every predetermined valid time or every time a broadcast signal or a confirmation request from the distribution server is received. By confirming whether or not the apparatus 100 is located in the same house, it is possible to appropriately execute the broadcast-related application having the same house restriction. Furthermore, by using the authentication information embedded in the broadcast signal for authentication at the distribution server, the validity of the distribution request can be ensured. If the authentication information of the broadcast signal is appropriately changed, the same program can be used. You can also confirm that you continue to watch.

  According to the portable information terminal cooperation technology according to the present embodiment described above, it is possible to realize the same in-house restriction for portable information terminals that cooperate with the broadcast receiving device.

  In the present embodiment, a case will be described in which the portable information terminal 700 acquires the broadcast cooperation information from the distribution server.

  FIG. 18B shows the procedure of this embodiment.

  First, before performing terminal cooperation, the portable information terminal 700 and the broadcast receiving device 100 each activate a cooperation control application that is an application for controlling terminal cooperation (S10101, S10102). In this state, the portable information terminal 700 issues a terminal cooperation request to the broadcast receiving device 100 (S10103). Next, the AIT is acquired from the broadcast signal (S10104). Information such as a URL about the distribution server is acquired from the information of the AIT, and the information is transmitted to the portable information terminal 700 (S10105). Next, the broadcast receiving apparatus 100 issues a time confirmation request to the distribution server (S10106), and based on this request, transmits time information from the distribution server to the broadcast receiving apparatus 100 (S10107). As a result, the authentication key can be issued in the latter stage in accordance with the time of the distribution server (S10115), but may be omitted if there is no problem in time lag.

  Thereafter, the process enters a loop control indicated by an arrow in S10127.

  First, the portable information terminal 700 issues an authentication key issuance request or a broadcast cooperative information distribution request to the broadcast receiving device 100 (S10109). The authentication key is used in a broadcast cooperation information distribution request to the distribution server in the latter stage (S10125). The broadcast cooperative distribution request in S10109 is a distribution request for information acquired from a broadcast signal, and corresponds to the procedure of S10126 in the subsequent stage.

  In any case, when the request of S10109 is issued from the portable information terminal, it is determined whether or not the application is a broadcast cooperative application having the same in-house restriction (S10111). Skip to step S10114. If all the broadcast cooperation applications have the same home restriction, the determination in S10111 is not performed, and the process proceeds to S10112. In S10112, it is determined whether or not the portable information terminal that issued the request is in the same house, and if there is no portable information terminal, the terminal cooperation is terminated (S10113). If it is located in the same house, the requested procedure, the acquisition of the broadcast cooperation information from the distribution server (S10125) or the acquisition of the broadcast cooperation information from the broadcast signal (S10126) are performed. The procedure of S10126 is also described because it may be obtained from the broadcast signal other than the acquisition from the distribution server.

  First, the procedure for acquiring the broadcast cooperation information from the distribution server (S10125) will be described.

  First, the broadcast receiver 100 issues an authentication key requested by the information cooperation terminal 700. At this time, it is assumed that the authentication key, including time information at the time of issuance, is valid only for a predetermined time (for example, 10 minutes). The distribution server checks the authentication information including whether or not the authentication key is within the valid time, and if the authentication is OK, the distribution of the broadcast cooperation information is permitted. Thereafter, distribution of information is permitted within the valid time, but distribution is stopped when the valid time has passed. For example, the streaming video cannot be viewed after the expiration time.

  The preset valid time may be stored in the distribution server, or the broadcast receiving apparatus 100 may acquire the valid time from a broadcast signal (for example, AIT) and incorporate the valid time information into the authentication key. The portable information terminal 700 is notified of the information of the validity time in advance, and is required to issue an authentication key before the validity time expires. Alternatively, the effective time is managed by the broadcast receiving apparatus 100, and before the effective time expires, it is confirmed that the portable information terminal 700 is in the same house, and then the broadcast receiving apparatus 100 automatically transmits the effective time to the portable information terminal 700. Alternatively, an authentication key may be issued.

  The effective time may be the same in one program or may be changed according to the progress of the program. In addition, if there is no setting of the valid time, the authentication may be performed once and the authentication is valid during the viewing of the program.

  Further, the authentication information described in the AIT may be incorporated in the authentication key used for authentication at the distribution server (S10117). Thereby, it can be confirmed that the request is a valid authentication request. If the authentication information described in the AIT is changed with the progress of the program, and if the distribution server does not perform authentication unless the authentication key incorporates information synchronized with the progress of the program, the same program can be used. You can see that you continue to watch. In this case, the information of the AIT is appropriately read and updated (S10124). Note that the authentication information to be incorporated in the broadcast signal may be incorporated as broadcast cooperation information in addition to being described in the AIT. Further, as a method of substantially changing the authentication information, a method of changing the URL itself of the distribution server in accordance with the progress of the program can be used. In this case, the URL is changed when the delivery server is the same and the entrance is different. However, the URL may be changed to a new delivery server due to a change in the broadcast cooperation application or the like. In this case, every time a change is made, the procedure of transmitting the distribution server information (S10105), requesting the time confirmation (S10106), and transmitting the time information (S10107) is performed.

  Next, a procedure (S10126) of acquiring broadcast cooperation information from a broadcast signal will be described.

  In this case, after it is confirmed that the portable information terminal 700 is located in the same house, the broadcast receiving apparatus 100 acquires the broadcast cooperation information from the broadcast signal (S10119), and subsequently distributes the information to the portable information terminal 700. (S10120).

  When the broadcast cooperation information is changed as the program progresses, a notification of the change may be issued from the broadcast signal (S10110), and the notification may be used to acquire the broadcast cooperation information. In this case, if it is obtained from the distribution server, the broadcast receiving apparatus 100 issues an authentication key to the portable information terminal (S10115), and notifies that there is a change notification. If it is within the valid time, the issuance of the authentication key may be omitted, and only the notification of the change notification may be performed. In the case of acquisition from a broadcast signal, the broadcast receiving device 100 acquires information (S10119) and distributes the information to the portable information terminal (S10120). In the case of acquisition from a broadcast signal, it may be confirmed that the portable information terminal 700 is located in the same house every time a change notification is made, or the confirmation is omitted if it is within the valid time as in the second embodiment. It does not matter. Here, the change notification from the broadcast signal (S10110) is described as being acquired from the broadcast cooperation information, but here, the event message is also described as being included in the broadcast cooperation information. Further, this change notification may be described in the AIT.

  After receiving (acquiring) and distributing the series of broadcast cooperation information, it is determined whether or not the broadcast receiving apparatus 100 continues viewing the same program (S10121). A response indicating that the cooperation is not permitted is sent to the cooperation control application, and the process ends (S10123). If the viewing is continued, the process returns to S10108, and the loop processing S10127 is continued.

  As described above, by including the time information in the authentication key used for the authentication of the distribution server and managing the effective time, it is possible to periodically confirm that the portable information terminal 700 is in the same house as the broadcast receiving device 100, It is possible to appropriately execute the broadcast cooperative app having the same home restriction. Furthermore, by using the authentication information embedded in the broadcast signal for authentication at the distribution server, the validity of the distribution request can be ensured. If the authentication information of the broadcast signal is appropriately changed, the same program can be used. You can also confirm that you continue to watch.

  According to the portable information terminal cooperation technology according to the present embodiment described above, even when the portable information terminal that cooperates with the broadcast receiving device acquires the broadcast cooperation information from the distribution server, it is possible to realize the same in-house restriction. .

  In the second and third embodiments, the procedure for realizing the same in-house restriction in the terminal cooperation has been described. However, the use from outside the house may be permitted depending on the broadcast cooperation application. In this embodiment, such a case will be described. For example, when a program such as television shopping is publicized or advertised, it is desirable for a broadcaster to be able to use the broadcast cooperation application regardless of whether the user is inside or outside the house. In the case of such a program, once registered in the broadcast receiving device 100, the use of the broadcast cooperative app may be permitted regardless of whether the portable information terminal 700 is at home. In this case, if there is a broadcast cooperation application that converts the broadcast video itself into streaming data and distributes the broadcast video from the broadcast receiving device 100 to the portable information terminal 700 via the Internet, the convenience is further enhanced. The streaming data may be encrypted by the broadcast receiving device 100 for copyright protection. Whether or not the broadcast cooperative app permits use from outside the home, including the distribution of the broadcast video outside the home, is described in data (for example, AIT) in the broadcast signal.

  FIG. 18C shows a specific procedure. Since some of the procedures are common to the second and third embodiments, the description of the parts overlapping with the second and third embodiments will be omitted. When receiving a terminal cooperation request from outside the home (S10203), the broadcast receiving device 100 checks whether the request source is a registered portable information terminal if the application is permitted to be used outside the home ( In step S10205, cooperation is permitted. Here, if necessary, authentication may be performed between the portable information terminal 700 and the broadcast receiving apparatus 100 for copyright protection of the broadcast video and the broadcast cooperation information (S10207). At this time, the authentication may be authentication in the distribution server (S10207). Information on the necessity of copyright protection and information on the authentication method of copyright protection are acquired from a broadcast signal (for example, described in AIT), and control is performed according to the information. When these pieces of information are not stored in the broadcast signal, the broadcast receiving apparatus 100 follows a predetermined method. For example, a predetermined copyright protection process may be performed. Further, when such information is not stored in the broadcast signal, it may be determined in advance that the broadcast receiving apparatus 100 does not perform the copyright protection processing.

  The following is a specific example of authentication for copyright protection. Only one of the following authentications may be performed. Alternatively, a plurality of authentications exemplified below may be performed in combination. Further, the authentication exemplified below may be combined with another authentication process not exemplified below.

[Authentication by ID and password]
When the portable information terminal 700 is registered in the broadcast receiving device 100, an ID and a password are issued, and the broadcast receiving device 100 permits cooperation by confirming the ID and the password.

[Use of encryption key]
In addition to the above-described authentication using the ID and the password, an encryption key for decrypting the encrypted video data and the like is transmitted from the broadcast receiving apparatus 100 to the portable information terminal. This encryption key may be obtained from a broadcast signal (for example, described in the AIT).

[Use of distribution server]
A method in which a distribution server issues an encryption key for decrypting encrypted video data or the like. The portable information terminal 700 transmits the ID and the password to the distribution server and acquires the encryption key. In this case, the location information (specifically, URL) of the distribution server is acquired from a broadcast signal (for example, described in the AIT), and the location information is transmitted from the broadcast receiving apparatus 100 to the portable information terminal 700. More secure. If the portable information terminal 700 cannot obtain the encryption key, it cannot decrypt a video or the like. Therefore, by requesting authentication from the broadcast receiving device 100 at the distribution server, it is possible to perform authentication for writing right protection. The authentication may be completed by notifying 700 that the encryption key has been acquired from the broadcast receiving apparatus 100. Note that billing by the distribution server may be performed.

[Mutual authentication of encryption key]
The encryption keys of the broadcast receiving apparatus 100 and the portable information terminal 700 are mutually authenticated, and the authentication is performed to obtain copyright protection authentication.

  If the information stored in the broadcast signal indicates that copyright protection is required by a predetermined method, if the copyright protection cannot be authenticated by the predetermined method, terminal cooperation is not permitted. Further, even when the broadcast signal is not specified and the authentication is performed by the default method of the broadcast receiving apparatus 100, if the copyright protection cannot be authenticated by the predetermined method, the terminal cooperation is not permitted.

  When the terminal cooperation is permitted, it is not checked whether the portable information terminal 700 exists in the same house thereafter, but a request from the portable information terminal 700 (S10211), autonomous control of the broadcast receiving apparatus 100, broadcast signal In accordance with the request (S10210), distribution of broadcast cooperative information to the portable information terminal 700 (S10217) and issuance of an authentication key for a distribution server (S10212). In this case, the control for setting the effective time does not have to be performed. The portable information terminal 700 outside the home acquires the broadcast cooperation information from the broadcast receiving device 100 or the distribution server using the issued authentication key (S10215). The authentication information issued from the broadcast signal (for example, described in the AIT) is incorporated into an authentication key issued by the broadcast receiving apparatus 100, and the distribution server uses the authentication key incorporating the authentication information acquired from the broadcast signal. If access is permitted, the use outside the home can be further optimized.

  Furthermore, in some cases, such as when discounting as a program viewing premium, it is better not to allow unlimited use of the broadcast cooperative app.In such a case, authentication must be performed once the mobile information terminal is in the same house. After that, it is preferable to use a method of permitting use of the distribution server even if the user is not in the same house. In this case, the portable information terminal 700 may not be registered in the broadcast receiving device 100.

  FIG. 18D shows a specific procedure in this case. Since the procedure is partially the same as that in FIG. 18C, the description of the overlapping part will be omitted. First, in a state where the portable information terminal 700 is in the same house as the broadcast receiving apparatus 100, the portable information terminal 700 makes a terminal cooperation request to the broadcast receiving apparatus 100. Is confirmed (S10305), and the cooperation is permitted. Here, if necessary, authentication may be performed between the portable information terminal 700 and the broadcast receiving device 100 for copyright protection of the broadcast video and the broadcast cooperation information (S10307). At this time, the authentication may be authentication in an external distribution server. Information on the necessity of copyright protection and information on the authentication method of copyright protection are acquired from a broadcast signal (for example, described in AIT), and control is performed according to the information. If such information is not stored in the broadcast signal, the broadcast receiving apparatus 100 follows a predetermined method. For example, a predetermined copyright protection process may be performed. Further, when such information is not stored in the broadcast signal, it may be determined in advance that the broadcast receiving apparatus 100 does not perform the copyright protection processing.

  The following is a specific example of authentication for copyright protection. Only one of the following authentications may be performed. Alternatively, a plurality of authentications exemplified below may be performed in combination. Further, the authentication exemplified below may be combined with another authentication process not exemplified below.

[Use of encryption key]
While the portable information terminal 700 is in the same house, an encryption key for decrypting the encrypted video data or the like is transmitted from the broadcast receiving device 100 to the portable information terminal. This encryption key may be obtained from a broadcast signal (for example, described in the AIT). Delivering this encryption key within the same house is regarded as authentication. Furthermore, if the encryption key cannot be obtained from the broadcast signal unless the program is at a certain point in time, and the delivery of the encryption key to the portable information terminal 700 is limited to the same house, the user must be in the same house at that time. Restrictions can be set, and can be used for premiums for viewing.

[Use of distribution server]
A method in which a distribution server issues an encryption key for decrypting encrypted video data or the like. The portable information terminal 700 transmits the ID and the password to the distribution server and acquires the encryption key. In this case, the location information (specifically, URL) of the distribution server is acquired from a broadcast signal (for example, described in the AIT), and the location information is transmitted from the broadcast receiving apparatus 100 to the portable information terminal 700. More secure. If the portable information terminal 700 cannot obtain the encryption key, it cannot decrypt a video or the like. Therefore, by requesting authentication from the broadcast receiving device 100 at the distribution server, it is possible to perform authentication for writing right protection. The authentication may be completed by notifying 700 that the encryption key has been acquired from the broadcast receiving apparatus 100. The access to the distribution server may be made in the house or outside the house. However, the location information of the distribution server cannot be obtained from the broadcast signal unless the program is at a certain point in time. If the delivery is limited to the same house, a restriction that the user must be in the same house at that time can be provided, and it can also be used to give a premium for viewing. Note that billing by the distribution server may be performed.

[Mutual authentication of encryption key]
The encryption keys of the broadcast receiving apparatus 100 and the portable information terminal 700 are mutually authenticated, and the authentication is performed to obtain copyright protection authentication. This authentication may be performed inside the house or outside the house.

  If the information stored in the broadcast signal indicates that copyright protection is required by a predetermined method, if the copyright protection cannot be authenticated by the predetermined method, terminal cooperation is not permitted. Further, even when the broadcast signal is not specified and the authentication is performed by the default method of the broadcast receiver 100, if the copyright protection cannot be authenticated by the predetermined method, the terminal cooperation is not permitted. The procedure after permitting the terminal cooperation is the same as the procedure in FIG.

  According to the portable information terminal cooperation technology according to the present embodiment described above, it is possible to realize the use of the portable information terminal that cooperates with the broadcast receiving device from outside the home while paying attention to copyright protection.

  In an actual use situation, it is more desirable to easily determine whether there is a terminal cooperation application by a program and which terminal cooperation application can be used. In the present embodiment, a method of displaying the availability status of the terminal cooperation application will be described. The terminal cooperation application indicates a broadcast cooperation application used in terminal cooperation.

  FIG. 19A is an example of the launcher screen (173b11) of the broadcast cooperation application when there is a terminal cooperation application. The broadcast cooperation application is displayed with a framed character icon. A broadcast cooperative application (173b12 to 173b14) for the broadcast receiving device 100 and a broadcast cooperative application (173b15 to 173b17) for the portable information terminal that are linked to the program being viewed are displayed. In the case of this example, the situation of the application is indicated by the thickness of the frame surrounding the character string and the color in the frame. The main applications A and B (173b12 and 173b13) and the terminal applications A and B (173b15 and 173b16) are available, and the main application C (173b14) and the terminal application C (173b17) are not available. . The state in which the terminal application is unavailable means that there is no portable information terminal 700 in a state capable of communicating with the broadcast receiving device 100, which has a function of executing the application.

  FIG. 19B is a screen after selecting the terminal application A in FIG. 19A. The state of each portable information terminal 700 relating to the terminal application A is shown. The portable information terminal displayed on this screen is a terminal that has been linked to or registered with the broadcast receiving device 100 in the past.

  The mobile terminal 1 (173b22) and the mobile terminal 2 (173b23) in which the frame of the icon is a solid line can communicate with the broadcast receiving apparatus 100, and the mobile terminal 3 (173b24) in which the frame is a dotted line. And that the portable terminal 4 (173b25) is not in a state where it can communicate with the broadcast receiving apparatus 100. The mobile terminal 1 (173b22) and the mobile terminal 3 (173b24) whose icons are white have a function of executing the terminal application A, and the mobile terminal 2 (173b23) and the mobile terminal 4 whose grays are inside the frame. (173b25) indicates that it has no function of executing the terminal application A. Further, when the application is already running on the terminal, an icon having a design indicating that fact may be used.

  In addition, icons are more easily understood visually using pictures, and examples thereof are shown below.

  FIG. 19C is an example of a launcher screen (173b31) showing a list of broadcast cooperation applications. Icons are shown for each type of the portable information terminal 700 in addition to the broadcast receiving device 100. 173b32 and 173b33 are icons indicating the broadcast receiving apparatus 100, 173b34 and 173b35 are icons indicating the smart phone type portable information terminal 700, and 173b36 is an icon indicating the head mounted display type portable information terminal 700. Each app is for the device indicated by the icon.

  In FIG. 19C, when the application cannot be used, a mark indicating that the application cannot be used (in this case, a circle with a hatched mark) is displayed over the picture of the device. In the case of the broadcast receiving apparatus 100, if the application is already running, a mark (in this case, a dot) may be displayed so as to overlap the mark. With this display, it is possible to prevent a useless operation of proceeding with the launcher procedure even though the execution has already been performed. In the case of the portable information terminal 700, a method is also possible in which a mark indicating that the application is being executed is displayed when all of the terminals that are in communication with the broadcast receiving device and can execute the application are executing the application.

  FIG. 19D is a screen (173b41) after the application C (173b34) is selected in FIG. 19C. The state of the portable information terminal 700 of the type corresponding to the application C is shown. On this screen, when the portable information terminal 700 does not have the function of executing the broadcast cooperation application, when the portable information terminal 700 is not in a state capable of communicating with the broadcast receiving apparatus 100, and when the broadcast cooperation application is already being executed, The mark to represent is displayed over the icon. In this example, a circle has a hatched mark (173b44, 173b46) when it does not have an execution function, a triangle exclamation mark (173b45, 173b46) when it is not in a communicable state, and a circle when it is already being executed. Mark (173b43) is displayed.

  Furthermore, it is desirable that there be a display method that allows the user to know that there is a broadcast cooperative app when the situation changes without having to start the launcher each time. For example, when the power is turned on, when the channel is changed, at the beginning of the program, or when the broadcast cooperative app is changed even during the program, the communication state between the broadcast receiving apparatus 100 and the portable information terminal 700 changes. In this case, when the execution status of the application changes, the icon is displayed for a predetermined time, and the state at that time is displayed.

  FIG. 19E shows an example in that case. When an icon indicating the type of each device is displayed, it indicates that there is a broadcast cooperation application corresponding to that type of device. In this case, a circle with a hatched mark indicates that there is no device of that type that is in a usable state that can execute the application. A circle with a dot indicates that the application is running on all available devices of that type.

  FIG. 19F is a display screen (10401) on portable information terminal 700. When requesting terminal coordination from the portable information terminal 700, it is more convenient to use which table shows which broadcast cooperative application is available on which broadcast receiving device 100. FIG. 19F shows an example of the list (10402). This table shows which broadcast receiving device 100 in the home can use the broadcast cooperation application corresponding to the program to be checked. Also, displaying the status of each broadcast receiving apparatus 100 further enhances convenience, particularly when used from outside the home. In this example, a display example is shown in which the program is being received, another program is being received, free is available, and another program is reserved (when recording of another program has been reserved in the middle of the program). Here, when a plurality of tuners are present in the broadcast receiving apparatus 100, displaying the status for each of the plurality of tuners further enhances convenience. In Table 10202, the branch numbers indicate the tuners in the same device. For example, the receiving device B-1 and the receiving device B-2 are tuners in the same broadcast receiving device 100. In the case of terminal coordination, if broadcast video and audio can be received as streaming data, there is no need to use the video section of the broadcast receiving apparatus 100, and broadcast can be used if the tuner in the broadcast receiving apparatus 100 can be used. Therefore, it is convenient to know the usage status of each tuner.

  In order to perform the display described in this embodiment, for each broadcast cooperation application, information indicating whether the application is compatible with the broadcast receiving device 100 or what type of portable information terminal 700 is compatible with the application. There must be. Further, information for executing the corresponding application in the broadcast receiving device 100 and the portable information terminal 700 is required. Such information can be acquired by the broadcast receiving apparatus 100 by, for example, writing the information in the AIT.

  According to the portable information terminal cooperation technology according to the present embodiment described above, it is possible to use a more convenient broadcast cooperation service by displaying information on the broadcast cooperation application, the broadcast receiving device 100, and the portable information terminal 700. Becomes

  Hereinafter, a sixth embodiment of the present invention will be described. The configuration, effects, and the like in this embodiment are the same as those in the first embodiment unless otherwise specified. Therefore, in the following, differences between the present embodiment and the first embodiment will be mainly described, and description of common points will be omitted as much as possible to avoid duplication.

  In the present embodiment, an example of the process of activating a broadcast cooperative app based on the AIT transmitted by the broadcast wave, particularly the operation of the broadcast receiving apparatus 100 in the following cases, will be described. In this case, the broadcast cooperative application is a broadcast managed application, and the broadcast cooperative application is a broadcast managed application based on information on the PMT and information (FIG. 6) such as the application control code 903 of the AIT and the activation priority 907. This is a case where an application is prescribed and instructed to start automatically with priority. Hereinafter, the broadcast managed application may be referred to as a “broadcast managed application”.

  The broadcast receiving apparatus 100 according to the sixth embodiment has a function of controlling the start processing of the broadcast cooperative app in which the automatic start is specified in the digital broadcast service in accordance with the selection by the user. The broadcast receiving apparatus 100 according to the sixth embodiment does not automatically start the broadcast cooperative app unconditionally when there is a rule or instruction for the automatic start, but satisfies the following conditions (1) to (3). Control to start automatically only when applicable. (1) When automatic start is set to be permitted in the user setting of the broadcast receiving device. (2) A case where a user having a predetermined terminal cooperating with the broadcast receiving apparatus is watching, in other words, a case where automatic start is set to be permitted in a user setting of the cooperating terminal. (3) When the user confirms the activation every time, and the result is affirmative.

  FIG. 20 illustrates a system configuration including the broadcast receiving device 100 according to the sixth embodiment and a usage example. The broadcast receiving device 100 receives a broadcast wave from the broadcast station server 300 via the radio tower 300t, and separates a video of a broadcast program from information such as AIT. The broadcast receiving device 100 appropriately acquires a broadcast cooperation application from the service provider server 400 based on information such as AIT. The AIT may include information instructing automatic start of a broadcast cooperative app that cooperates with a broadcast program.

  There is one or more portable information terminals 700 that perform terminal cooperation with the broadcast receiving device 100. For example, one broadcast receiving apparatus 100 can cooperate with each of the portable information terminals 700 of two users and is shared. For example, there is a terminal A owned by the user A and a terminal B owned by the user B. The present invention is not limited to this, and one user may use a plurality of portable information terminals 700.

  The broadcast receiving apparatus 100 according to the sixth embodiment includes an application activation control unit 2000 including a user selection unit 2001. The user selection unit 2001 is a unit for selecting whether to allow or not to start and execute the broadcast cooperative app, based on the operation of the user of the broadcast receiving apparatus 100 and the portable information terminal 700. The user selection unit 2001 includes, for example, an instruction input unit and a user setting unit in the broadcast receiving device 100 and the portable information terminal 700. When the automatic start of the broadcast cooperative application is instructed by the AIT, the application start control unit 2000 responds to the user and the user selection unit 2001 to select whether to allow or not to start and execute the broadcast cooperative application. Controls the launch of linked apps.

[Automatic launch of broadcast managed application]
In the sixth embodiment, first, when it is defined that the broadcast managed application is automatically started with priority, the broadcast receiving apparatus 100 checks the information such as PMT and AIT as appropriate and starts the broadcast managed application. Is the same as that described in the first embodiment with reference to FIG. 7A. In the example of FIG. 7A, whether the target broadcast managed application can be executed in the broadcast receiving apparatus 100 is confirmed by confirming the application profile 904 of the AIT (S105). When the executable is confirmed, the broadcast managed application is always automatically started regardless of the selection of the user of the broadcast receiving apparatus 100.

  However, the possibility that the user of the broadcast receiving apparatus 100 does not want to automatically start the broadcast managed application, for example, because the user wants to concentrate on viewing the broadcast program, should be considered. The broadcast receiving apparatus 100 according to the sixth embodiment includes an application activation control unit 2000 as a control function in consideration of this possibility. That is, the broadcast receiving apparatus 100 according to the sixth embodiment has a case in which there is an instruction for automatic start of the broadcast managed application priority based on the information such as the PMT and the AIT, and a case where it is confirmed that the broadcast managed application can be executed based on the information such as the AIT. Also, the activation of the application is controlled according to the user's selection of whether or not to activate. Hereinafter, an example in which the availability of the broadcast managed application is automatically controlled will be described.

[Operation sequence at the time of starting broadcast managed application (1)]
FIG. 21 illustrates a first configuration example and a processing example of the broadcast receiving apparatus 100 according to the sixth embodiment in which a broadcast managed application that is a broadcast cooperative application is specified to be started preferentially. An example of an operation sequence at the time is shown. FIG. 21 shows a series of flow from when the broadcast receiving apparatus 100 appropriately checks the information of the PMT and the AIT, and further controls whether or not a predetermined broadcast cooperative app can be automatically activated according to a user's selection. In the first configuration example, the user setting in the broadcast receiving apparatus 100 is used as the user selection unit 2000.

  In FIG. 21, the broadcast receiving apparatus 100 obtains a TS by performing channel selection processing of a channel desired by the user by the tuner / demodulation unit 131 of FIG. 2A. Next, the broadcast receiving apparatus 100 acquires the PMT data string separated by the first separation unit 132 by the main control unit 101 (S1101), and confirms the activation priority described in the acquired PMT (S1102). The broadcast receiving apparatus 100 confirms in the processing of S1101 and S1102 that the start priority of the broadcast managed application that is the broadcast cooperative application is high.

  Upon confirmation, the broadcast receiving apparatus 100 acquires the AIT data string separated by the first separation unit 132 by the application control unit 161 (S1103), and confirms the application control code 903 of the acquired AIT data string (S1104). . In the processing of S1103 and S1104, when the application control code 903 is “automatic start”, that is, when the automatic start of the broadcast cooperative application is specified in the processing of S1103 and S1104, the broadcast receiving apparatus 100 further executes the application of the acquired AIT data sequence. The profile 904 is confirmed (S1105).

  In step S1105, the broadcast receiving apparatus 100 confirms that the broadcast receiving apparatus 100 can execute the broadcast cooperative application designated by the AIT by checking the information of the application profile 904. If the execution is confirmed, the broadcast receiving apparatus 100 further refers to the operation setting value stored in the storage unit 110 by the application control unit 161. Thereby, the broadcast receiving apparatus 100 confirms whether or not the automatic setting of the broadcast cooperative app is permitted in the user setting of the broadcast receiving apparatus 100 (S1106).

  The operation setting value indicating whether or not the broadcast cooperative app can be automatically started can be selected and set by the user according to his / her preference using a function setting menu of the broadcast receiving apparatus 100 or the like. The broadcast receiving apparatus 100 provides a user with a function setting menu on a screen or the like as a user selection unit 2001. The user can perform user settings relating to various functions by operating the remote control of the broadcast receiving apparatus 100 and the associated portable information terminal 700 on the function setting menu on the screen. The broadcast receiving device 100 stores the user setting information in the function setting menu as an operation setting value in a memory in the broadcast receiving device 100.

  In the process of S1106, the broadcast receiving device 100 confirms that the automatic start of the broadcast cooperative app is not allowed (“No”), that is, that the user does not want the automatic start of the broadcast cooperative app (S1107). -No), the process of FIG. 21 ends. That is, the application control unit 161 does not acquire and start the broadcast cooperation application specified in the AIT.

  On the other hand, when the broadcast receiving apparatus 100 confirms in the process of S1106 that the automatic start of the broadcast cooperative app is permitted (“OK”), that is, that the user desires the automatic start of the broadcast cooperative app (S1107-Yes), and it progresses to S1108. In the process of S1108, the broadcast receiving apparatus 100 broadcasts a predetermined service provider server 400 to the predetermined service provider server 400 via the LAN communication unit 121 based on the information described in the application acquisition destination information 905 of the AIT by the application control unit 161. Send a request to distribute the cooperative app.

  The service provider server 400 that has received the broadcast cooperative application distribution request in S1108 performs authentication processing of the broadcast receiving device 100 as necessary based on the control of the application management / distribution execution unit 4103 in FIG. The predetermined broadcast cooperation application stored in the application storage area 4013 is distributed via the LAN communication unit 421 (S1109). A known method may be used for the authentication processing, and a detailed description thereof will be omitted.

  Next, the broadcast receiving apparatus 100 activates a predetermined broadcast cooperation application distributed from the service provider server 400 and received by the application engine 162 via the LAN communication unit 121 under the control of the application control unit 161 ( S1110). As a result, the broadcast cooperation application is executed, and an execution screen of the application is displayed.

  As a modified example, the processing of S1106 to S1107 may be performed after the acquisition of the broadcast cooperation application in the processing of S1108 to S1109.

  As in the first configuration example of FIG. 21 described above, in the sixth embodiment, the broadcast cooperative app can be activated when it is confirmed that the automatic activation is permitted by the user setting of the broadcast receiving apparatus 100.

[Operation sequence at the time of starting broadcast managed application (2)]
FIG. 22 is a diagram illustrating a second configuration example and a processing example of the broadcast receiving apparatus 100 according to the sixth embodiment in which a broadcast managed application that is a broadcast cooperative application is defined to be activated with priority. 5 shows an example of an operation sequence at the time of starting different broadcast cooperation applications. FIG. 22 shows the cooperative operation with the broadcast receiving apparatus 100, that is, whether or not the broadcast cooperative app can be automatically started by referring to the operation setting value stored in the portable information terminal 700 that performs the above-described terminal cooperating, that is, the user setting information. This is an example in which confirmation is performed. In the second configuration example, user setting in the portable information terminal 700 is used as the user selection unit 2000. The user selects and sets whether or not the mobile information terminal 700 is allowed to automatically start the broadcast cooperative app.

  22, the broadcast receiving apparatus 100 first performs the processing of S1201 to S1205, which is the same as the processing of S1101 to S1105 in FIG. If it is confirmed in S1205 that the application coordination application 904 can execute the broadcast cooperative app specified by the AIT in S1205, the broadcast receiving apparatus 100 performs the process of S1206. In step S1206, the broadcast receiving device 100 causes the application control unit 161 to transmit a user setting confirmation request to the mobile information terminal 700 that is performing the cooperative operation. Here, it is assumed that there is, for example, the terminal A in FIG.

  In response to the user setting confirmation request received via the LAN communication unit 721 by the cooperation control execution unit 7102 of FIG. 5B, the portable information terminal 700 sets the operation setting values of the broadcast receiving device 100 stored in the storage unit 710 of FIG. 5A. See Thereby, the portable information terminal 700 confirms whether or not automatic start of the broadcast cooperative app in the broadcast receiving device 100 is possible in the user setting in the portable information terminal 700 (S1207). The portable information terminal 700 causes the cooperation control execution unit 7102 to transmit the result of the confirmation as to whether or not the automatic activation is possible to the broadcast receiving device 100 via the LAN communication unit 721 as the result of the user setting confirmation (S1208).

  The operation setting value of whether or not the broadcast cooperative app can be automatically started by the broadcast receiving apparatus 100, which is the user setting information of the portable information terminal 700, can be set by, for example, the following means. That is, in the cooperative operation state between the broadcast receiving apparatus 100 and the portable information terminal 700, the user selects and sets according to his / her preference using a cooperative function setting menu or the like, which is one of the function setting menus of the portable information terminal 700. it can. The portable information terminal 700 provides the user with the function setting menu on a screen or the like. The user selects the link function setting menu from the function setting menu. The coordination function setting menu is a menu in which settings relating to the coordination operation can be made. The user can make a setting regarding whether or not the broadcast receiving application can be automatically started in the broadcast receiving apparatus 100 by an operation selected from the cooperation function setting menu. The portable information terminal 700 stores the user setting information in the function setting menu as an operation setting value in a memory in the portable information terminal 700.

  Through the processing of S1206 to S1208, the broadcast receiving device 100 determines that the automatic start of the broadcast cooperative app is not permitted, that is, the user who owns the portable information terminal 700 performs the automatic start of the broadcast cooperative app on the broadcast receiver 100. When it is confirmed that the user does not want to do so (S1209-No), the present process of FIG. 22 ends. That is, the application control unit 161 does not acquire and start the broadcast cooperation application specified in the AIT.

  On the other hand, the broadcast receiving apparatus 100 indicates that the automatic start of the broadcast cooperation application is permitted, that is, that the user owning the portable information terminal 700 desires the automatic start of the broadcast cooperation application in the broadcast reception apparatus 100. If confirmed (S1209-Yes), the process proceeds to S1210.

  In step S1210, the broadcast receiving apparatus 100 requests the predetermined service provider server 400 to distribute the broadcast cooperative application to the predetermined service provider server 400 via the LAN communication unit 121 based on the information described in the application acquisition information 905 of the AIT by the application control unit 161. Send

  The service provider server 400 that has received the broadcast cooperative application distribution request in S1210 performs authentication processing of the broadcast receiving device 100 as necessary based on the control of the application management / distribution execution unit 4103, and then stores the application storage. The predetermined broadcast cooperation application stored in the area 4013 is distributed via the LAN communication unit 421 (S1211).

  Next, the broadcast receiving apparatus 100 activates a predetermined broadcast cooperation application distributed from the service provider server 400 and received by the application engine 162 via the LAN communication unit 121 under the control of the application control unit 161 ( S1212).

  As in the second configuration example of FIG. 22 described above, in the sixth embodiment, there is a portable information terminal 700 that cooperates with the broadcast receiving device 100, and it is confirmed that the user setting of the portable information terminal 700 allows automatic activation. If so, the broadcast cooperative app can be activated.

  As a modified example, when the portable information terminal 700 is not operating in cooperation with the broadcast receiving device 100 at the time of the user setting confirmation in FIG. 22 described above, before the processes of S1206 to S1208, S606 to S611 of FIG. May be performed. Thus, in this modified example, the cooperative control application is activated to cause the portable information terminal 700 to start the cooperative operation with the broadcast receiving device 100, and the user setting is confirmed in this state.

  Further, as a modified example, in the following cases, an embodiment in which control is performed to select the Yes side in S1209 and an embodiment in which control is performed so as to select the No side in S1209 are possible. This case includes a case where there is no portable information terminal 700 to which the user setting confirmation request is transmitted in S1206, a case where there is no response to the request, and a case where the user setting confirmation result has not been correctly acquired in S1208. This case corresponds to a situation where there is no portable information terminal 700 that can cooperate with the terminal at that time, a situation where communication between the broadcast receiving apparatus 100 and the portable information terminal 700 is temporarily disabled, and the like. In the former embodiment, the permission of activation by the user setting could not be confirmed, but the broadcast cooperation application is activated. In the latter embodiment, the broadcast cooperative app is not started because the start permission by the user setting cannot be confirmed. Which control operation is to be adopted in the above-described modified example is defined by the specification of the broadcast receiving apparatus 100 or allows a user to set a selection.

  As a modified example, the processing of S1206 to S1209 may be performed after the acquisition of the broadcast cooperation application in the processing of S1210 to S1211.

[Operation sequence when starting broadcast managed application (3)]
FIG. 23 is a diagram illustrating a third configuration example and a processing example of the broadcast receiving apparatus 100 according to the sixth embodiment, in which a broadcast management application that is a broadcast cooperation application is defined to start preferentially. 4 shows an example of an operation sequence when starting an application. FIG. 23 is an example in which the user confirms in real time whether or not the broadcast cooperative app can be activated by a message on the screen in real time. In the third configuration example, an instruction input from the portable information terminal 700 to the broadcast receiving device 100 is used as the user selection unit 2000.

  23, the broadcast receiving apparatus 100 first performs the processing of S1301 to S1305 which is the same as the processing of S1101 to S1105 in FIG. When the broadcast receiving apparatus 100 confirms in step S1205 that the execution of the broadcast cooperative app specified in the AIT has been confirmed by confirming the application profile 904, the broadcast receiving apparatus 100 performs the process of step S1306. In step S1306, the broadcast receiving device 100 causes the application control unit 161 to display a start-up permission / non-permission confirmation screen on the video display unit 173 for allowing the user to select whether to permit the start of the broadcast cooperative app.

  The user selects whether or not to activate the broadcast cooperative app on the activation / non-permission confirmation screen displayed in S1306 by using the portable information terminal 700 or the remote controller as the operation means (S1307). The broadcast receiving apparatus 100 receives the information of the selection as an instruction input.

  If the broadcast receiving apparatus 100 does not select the activation of the broadcast cooperative app according to the result of the user's activation permission / non-permission selection in S1307, that is, if the user does not permit activation at this time (S1308-No), This process of FIG. 23 ends. That is, the application control unit 161 does not acquire and start the broadcast cooperation application specified in the AIT.

  On the other hand, the broadcast receiving apparatus 100 proceeds to S1309 when the user selects the activation of the broadcast cooperation application in S1307, that is, when the user permits the activation at this time (S1308-Yes). In the process of S1309, the broadcast receiving apparatus 100 requests the predetermined service provider server 400 to distribute the broadcast cooperative application to the predetermined service provider server 400 via the LAN communication unit 121 based on the information described in the application acquisition destination information 905 by the application control unit 161. Send

  The service provider server 400 that has received the distribution request for the broadcast cooperative app performs authentication processing of the broadcast receiving apparatus 100 as necessary based on the control of the application management / distribution execution unit 4103, and then executes the application storage area 4013. Is distributed via the LAN communication unit 421 (S1310).

  Next, the broadcast receiving apparatus 100 activates a predetermined broadcast cooperation application distributed from the service provider server 400 and received by the application engine 162 via the LAN communication unit 121 under the control of the application control unit 161 ( S1311).

  As a modified example, the processing of S1306 to S1308 may be performed after the acquisition of the broadcast cooperation application in the processing of S1309 to S1310.

  As in the third configuration example of FIG. 23 described above, in the sixth embodiment, the user can confirm the activation on the screen each time, and when the permission is confirmed, the broadcast cooperation application can be activated.

  In the example of FIG. 23 described above, the portable information terminal 700 is caused to function as an operation unit of the broadcast receiving apparatus 100 in cooperation with the terminal, and the activation is determined. However, the present invention is not limited to this, and an embodiment in which the above-described activation is selected using a remote controller or the like provided in the broadcast receiving apparatus 100 as the main body is also possible.

[Startup confirmation screen]
FIG. 24 shows an example of a screen for confirming whether or not the broadcast receiving apparatus 100 can be activated, which is displayed by the process of S1306 in FIG. In the present embodiment, a message box 173f1 is displayed on the screen of the video display unit 173 in FIG. The message box 173f1 includes a message indicating that a predetermined broadcast cooperative application is usable, and displays “Yes” and “No” buttons for selecting whether to activate the broadcast cooperative application. An example of the message is "Broadcast cooperative application XXX is available. Do you want to start broadcast cooperative application XXX?" Another example of the message is "start of the broadcast cooperation application XXX is specified, and the start is possible, but is the start permitted?"

  In the state where the message box 173f1 shown in FIG. 24 is displayed, the user selects whether or not to start using the operation means (S1307). For example, the user selects “Yes” or “No” on the basic screen 741 a of the cooperative control application of the portable information terminal 700 in FIG. 10A by using the cursor key 741 ac and the enter key 741 ad. Thus, the user can select whether to allow the broadcast cooperative app presented in the message box 173f1 on the broadcast receiving apparatus 100 to be activated or not according to his / her convenience or situation at that time.

  As a modified example, instead of the message box 173f1, the icon 173b0 indicating the existence of the cooperative application as shown in FIG. Is also good. In this case, for example, the user presses the cooperation application key 741a9 on the basic screen 741a of the cooperation control application. As a result, a predetermined broadcast cooperation application is activated. If the cooperative application key 741a9 corresponding to the selection of the icon 173b0 has not been pressed for a predetermined time or more, the display of the icon 173b0 may be controlled to be deleted.

[Effects]
As described above, according to each configuration example of the broadcast receiving apparatus 100 of the sixth embodiment, the provision and instruction of the automatic start of the broadcast managed application priority by the PMT and the AIT are provided, and the execution of the broadcast managed application by the AIT is confirmed. In such a case, the activation of the broadcast managed application can be appropriately controlled in accordance with the user's selection. That is, according to the broadcast receiving apparatus 100 of the present embodiment, it is possible to execute a function with higher added value.

  Which one of the above-described first to third configuration examples and various modifications is to be adopted is specified as a specification of the broadcast receiving apparatus 100 or the like, or is set by a user with respect to the broadcast receiving apparatus 100 or the like. Make it possible. For example, in the configuration examples of FIGS. 21 and 22, as operation setting values according to user settings, (a) “Allow activation of broadcast managed application (permitted)” and (b) “Activation of broadcast managed application is not permitted (No )]]. The present invention is not limited to this. As a modified example, in addition to the above (a) and (b), multi-values including (c) “query terminal” and (d) “confirm on screen each time” are set as user settings. May be selectable. The broadcast receiving apparatus 100 of this modification performs the control operation according to the first to third configuration examples in accordance with the set value selected by the user. In the case of the setting of (c), the processing of the second configuration example is performed, and in the case of the setting of (d), the processing of the third configuration example is performed.

  In particular, in the first configuration example of FIG. 21, it is possible to control the activation of the broadcast cooperative app according to the user's setting in advance for the broadcast receiving apparatus 100. The user can change the settings as appropriate according to his / her convenience and use the broadcast cooperation application.

  FIG. 25 shows an example in which a menu for user setting is displayed on the screen of the broadcast receiving device 100. A menu 173f2 for user setting is displayed on the screen according to an operation of the remote controller or the like by the user. In the case of the first configuration example, the menu 173f2 includes "allow start of the broadcast managed application" as one of the setting items. This item corresponds to “whether or not to allow automatic start when the automatic start of the broadcast cooperation application is specified”. The user can set whether or not to correspond to the above (a) and (b) by turning on / off the button in the setting item of the menu 173f2. The same function can be realized on the screen of the portable information terminal 700.

  In particular, in the second configuration example of FIG. 22, it is possible to set whether or not the broadcast managed application can be automatically started for each user who owns the portable information terminal 700. It is also possible to select whether to automatically start the managed application.

  An example of the above setting and use will be described with reference to FIG. As the user settings in the portable information terminal 700, the terminal A of the user A has the setting A, and the terminal B of the user B has the different setting B. For example, setting A indicates that the automatic start of the broadcast cooperative app is “OK”, and setting B indicates that the automatic start of the broadcast cooperative app is “NO”. At the time of the processing of S1206 to S1209 in FIG. 22, for example, when only the terminal A of the user A is performing the cooperative operation, the terminal A is confirmed and the activation is permitted. When only the terminal B of the user B operates in cooperation, the terminal B is confirmed and the activation is not permitted. In this manner, whether or not the broadcast cooperative app can be activated can be set in units of the portable information terminal 700 of each user, and the broadcast cooperative app can be activated and used depending on the presence or absence of the cooperative portable information terminal 700 at that time. is there.

  As a modification, a control operation can be performed in consideration of a combination of both the specification or user setting in the broadcast receiving device 100 and the specification or user setting in the portable information terminal 700. For example, in the embodiment in which the contents of the user setting in the portable information terminal 700 are prioritized over the user settings in the broadcast receiving apparatus 100, the contents of the user setting in the broadcast receiving apparatus 100 are prioritized over the user setting in the portable information terminal 700. Either of the embodiments is possible.

  In the second configuration example, the user may be allowed to make a setting as to whether or not to inquire of the portable information terminal 700 whether or not to activate the broadcast cooperation application. In this case, a setting item corresponding to the above (c) “Contact terminal” is provided in the user setting menu 173f2 in FIG.

  In particular, in the third configuration example shown in FIG. 23, it is possible to control whether or not to start the broadcast managed application prepared for each broadcast program. The user sees the broadcast managed application and the confirmation information presented on the screen, and can permit the activation if the user wants to activate the application at that time, and can disallow the activation if the user does not want to activate the application at that time. .

  Further, in the third configuration example, it may be possible to allow a user to set whether or not to confirm whether or not to start the broadcast cooperation application on the screen each time. In this case, in the user setting menu 173f2 of FIG. 25, setting items corresponding to the above-mentioned (d) “Confirm on each screen” are provided.

  Other examples include the following. In the other embodiment, even when the user selects “b” or not in the configuration example of FIG. 21 or FIG. 22 in advance and sets it, the broadcast managed application is forced regardless of the set value. Provide an option to start the program dynamically. In this embodiment, for example, in the data configuration of the AIT shown in FIG. 6, in addition to (1) to (4), a setting value of (5) "forced start" is prepared as a parameter setting value of the application control code 903. I do. Alternatively, an item of “forced start setting” may be separately prepared as one of the parameters of the AIT (one of the “other information” in FIG. 6). As these setting values, for example, “valid” and “invalid” can be selected.

  Further, when the setting value of the application control code 903 is (5) “Forced startup” or when the value of the item of “Forced startup setting” is “Valid”, the broadcast receiving apparatus 100 Control is performed as follows. That is, the broadcast receiving apparatus 100 controls to forcibly start the broadcast managed application even when the operation setting value is set to (b) or not. In other words, in the control of this embodiment, the forced activation is provided as a higher-priority item and a higher priority item than the user-selected item related to the automatic activation described above. In the case of the embodiment in which the option of forced startup as described above is provided, for example, an application for displaying emergency information from a broadcasting station or an application necessary for producing a specific CM, etc., is highly required to be displayed and provided. The application can be suitably displayed and provided to the user.

  As another embodiment, when the broadcast cooperative app is pre-installed inside the broadcast receiving apparatus 100, processing such as acquisition of the broadcast cooperative app to the service provider server 400 described above (for example, S1108 to S1110 in FIG. 21) ) Becomes unnecessary.

  The information included in the broadcast wave for controlling the broadcast cooperative application is not limited to PAT or AIT, and can be applied. For example, one of the parameters (901 to 909) of the AIT in FIG. 6 may be separated and configured and provided as independent control information. The control information may be provided in a form included in the broadcast wave, or may be provided in a form different from the broadcast wave. The control information may be set in the device in advance.

  Hereinafter, a seventh embodiment of the present invention will be described. The configuration, effects, and the like in this embodiment are the same as those in the first embodiment unless otherwise specified. Therefore, in the following, differences between the present embodiment and the first embodiment will be mainly described, and description of common points will be omitted as much as possible to avoid duplication.

  Since the broadcast cooperation application, which is an application used in the broadcast communication cooperation system of the present embodiment, is configured by an HTML document, it can be linked to another HTML document on the network. The operation such as start / end of the broadcast managed application is controlled based on the AIT application control code 903 included in the broadcast signal of the broadcast wave. The non-broadcast managed application or general application is not controlled in operation such as start / end by the broadcast signal. Hereinafter, the non-broadcast managed application may be referred to as “non-broadcast application”, and the general application may be referred to as “general application”.

  In the seventh embodiment, it is assumed that a transition from a broadcast managed application to a non-broadcast application or a general application is possible because a link in an HTML document constituting the broadcast cooperation application is possible. In the seventh embodiment, it is assumed that the non-broadcast application and the general application can be directly started from the above-described broadcast cooperative app launcher screen in response to a user's instruction operation. For example, a broadcasting station, a service provider, or the like includes, in an HTML document of a broadcast managed application, information of a transition instruction to another HTML document that constitutes a non-broadcast application or the like by describing a link such as a URL. . In such a case, a transition from the broadcast managed application to a non-broadcast application or the like may occur.

  Since the non-broadcast application and the general application are not controlled in operation such as start / end by the broadcast signal, the user may execute the non-broadcast application or the general application while watching the broadcast program. Then, when the user is running a non-broadcast application or the like while watching a broadcast program, there may be a case where further activation of a broadcast managed application associated with the broadcast program is required. The request includes, for example, an instruction to start using the application control code 903 of the AIT included in the broadcast signal. That is, in this case, it is required to execute the non-broadcast application or the general application and the broadcast managed application in parallel, or to select one of them. It is technically possible to execute a plurality of different types of applications in parallel in this way, but it may not be desirable in terms of control and may be inconvenient for the user.

  Therefore, the broadcast receiving apparatus 100 according to the seventh embodiment has a function of controlling duplication or parallel activation of the applications or activation and termination of each application so as to appropriately cope with the above situation. When the activation and execution of the second application are requested during the execution of the first application, the function controls operations including activation and termination of those applications according to the user's selection. In particular, this function is used to terminate a non-broadcast application or start a broadcast managed application in response to a user's instruction input or setting when a request to start a broadcast managed application is received during execution of a non-broadcast application or the like. Control. In the seventh embodiment, an example of the control operation of the broadcast receiving apparatus 100 in the above-described case and situation will be described.

  An example of the control according to the user selection by the above function is as follows. (1) The function activates and executes a target broadcast managed application while continuing the non-broadcast application and the general application being executed at the time of the request. (2) The function terminates the non-broadcast application or general application being executed at the time of the request, and activates and executes the target broadcast managed application. (3) The function keeps the non-broadcast application or general application being executed at the time of the request being received, and does not activate or execute the target broadcast managed application.

  The means of user selection by the above function is as follows. (A) The above function is, when the above request is received, information for notifying the user of a situation in which a request to start a broadcast managed application different from the running non-broadcast application, etc., and an application to be started or terminated Alternatively, information for allowing the user to select the control operation is displayed on the screen. This function accepts a user's operation of inputting a selection instruction on a screen. The function executes, for example, the content of the control selected from the above (1) to (3) according to the user's selection. (B) The function accepts a user setting operation by the user in advance. The function executes, for example, the contents of the control selected from the above (1) to (3) according to the confirmation of the user setting information when the request is received.

  FIG. 26 illustrates a system configuration including the broadcast receiving apparatus 100 according to the seventh embodiment and a usage example. The broadcast receiving device 100 receives a broadcast wave from the broadcast station server 300 via the radio tower 300t, and separates a video of a broadcast program from information such as AIT. The broadcast receiving device 100 appropriately acquires a broadcast managed application that is a broadcast cooperative application from the service provider server 400 or the like based on information such as the AIT. In addition, the broadcast receiving apparatus 100 appropriately acquires a non-broadcast application or a general application from the service provider server 400 or another application server 500 or the like. Further, there may be a portable information terminal 700 that performs terminal cooperation with the broadcast receiving device 100, and various applications are obtained and executed between the broadcast receiving device 100 and the portable information terminal 700 in the terminal cooperation state. Is also good.

  The broadcast receiving apparatus 100 according to the seventh embodiment includes a multiple application execution control unit 2600 including a user selection unit 2601. The user selection unit 2601 is a unit that selects, based on the operation of the user of the broadcast receiving device 100 and the portable information terminal 700, the contents of control such as operations including activation and termination of a plurality of types of applications and parallel execution. . The user selection unit 2601 includes, for example, an instruction input unit that receives and processes an instruction input in the broadcast receiving device 100, the portable information terminal 700, or the like according to the above (a). The user selection unit 2601 includes, for example, a user setting unit that receives and processes user settings according to the above (b).

  The multi-application execution control unit 2600 is provided by the user and the user selection unit 2601 when, for example, a broadcast program AIT is instructed to start a broadcast managed application while a broadcast program is being viewed and a non-broadcast application or a general application is being executed. In accordance with the selection of the control operation corresponding to the case, the control of the termination of the non-broadcast application, the activation of the broadcast managed application, and the like are controlled.

[Examples of multiple types of apps]
FIG. 27 illustrates an example of a document configuration of a plurality of types of applications, activation of each application, transition between each application, and the like. The broadcast wave 2010 includes video of a broadcast program, information such as AIT, and information such as BML. As described above, in the broadcast communication cooperation function, the AIT informs the broadcast receiving apparatus 100 of the existence of the broadcast cooperation application and instructs control such as activation and termination thereof. For example, the broadcast managed application 2011 is activated by the AIT information included in the broadcast wave 2010.

  In the seventh embodiment, the broadcast cooperation applications are roughly classified into (a) a broadcast managed application, (b) a non-broadcast application, and (c) a general application. The broadcast managed application operates in a broadcast reception state based on a control signal included in a broadcast signal, and is permitted to access a broadcast resource. The non-broadcast application operates in a state where start / end and the like are not controlled by the broadcast signal, and access to the broadcast resource is permitted based on authentication or the like. General applications operate independently of broadcast signals and are not allowed to access broadcast resources.

  In FIG. 27, App1, which is the broadcast managed application 2011, includes four documents, for example, HTML11 to HTML14. App2, which is the non-broadcast application 2012, is composed of two documents, for example, HTML21 to HTML22. App3, which is the general application 2013, is composed of two documents, for example, HTML31 to HTML32. Each HTML document can be transited by a link indicated by a solid arrow. For example, transition from HTML1 of App1 to HTML21 of App2 or HTML31 of App3 is possible. Dashed arrows indicate examples of transition between HTML documents.

  In FIG. 27, for example, in response to the user operation 2020 on the above-described broadcast cooperative app launcher screen, App2 as the non-broadcast application 2012 and App3 as the general application 2013 can be activated. App2 is executed by reading HTML21, for example, and App3 is executed by reading HTML31, for example.

  The following is an example of the case where each application is executed independently during reproduction of a broadcast program (for example, broadcast program A) by the broadcast wave 2010. (A1) Start of App1, which is the broadcast managed application 2011, is instructed by the AIT, and App1 is started and executed. App1 is permitted to access broadcast program A. When the end of App1 is instructed by the same AIT, App1 is ended.

  (A2) Based on a user's selection operation such as inputting an instruction, a start of App2, which is a non-broadcast application 2012, is instructed by a broadcast cooperative app launcher screen, a link from the HTML 13 of App1, and the like, and App2 is started and executed. Is done. App2 is permitted to access the broadcast program A. When the termination of App2 is instructed, App2 is terminated. (A3) Similarly, on the basis of a user's selection operation, the broadcast cooperative app launcher screen or the link from the HTML 13 of App1 is instructed to start App3, which is the general application 2013, and App3 is started and executed. . App3 is not permitted to access the broadcast program A. When the termination of App3 is instructed, App3 is terminated.

[Operation sequence when starting broadcast managed application]
FIG. 28 illustrates an operation sequence of control in the broadcast receiving apparatus 100 according to the seventh embodiment when a broadcast managed application is requested by the AIT of a broadcast signal while a non-broadcast application is being viewed while a broadcast program is being viewed. Show. In the following, the case of a non-broadcast application will be described, but the case of a general application is also possible. In FIG. 28, it is assumed that the start of the broadcast managed application is specified and instructed by information on the PMT and information such as the application control code 903 of the AIT and the start priority 907.

  In the broadcast receiving apparatus 100, while the user is viewing a broadcast program, the activation of the non-broadcast application is instructed in response to, for example, an operation of the user selecting any desired non-broadcast application from the broadcast cooperative app launcher screen. Then, the broadcast receiving apparatus 100 displays the execution screen of the non-broadcast application on the broadcast program screen, for example (S1401). When the broadcast program is switched in the state of S1401, the content of information such as PMT and AIT in the broadcast signal is updated. Even if the update is performed, the non-broadcast application continues its execution state because its operation such as start / end is not controlled by the broadcast signal.

  Next, the broadcast receiving apparatus 100 acquires the PMT data sequence separated by the first separation unit 132 by the main control unit 101 (S1402), and checks the activation priority described in the PMT (S1403). In the processing of S1403, for example, it is confirmed that the start priority of the broadcast managed application is high. Then, the broadcast receiving device 100 acquires the AIT data sequence separated by the first separating unit 132 by the application control unit 161 (S1404), and confirms the application control code 903 of the acquired AIT data sequence (S1405). If the application control code 903 is “automatic start” in the processing of S1405, the broadcast receiving apparatus 100 further checks the application profile 904 of the AIT data sequence (S1406). In S1406, the broadcast receiving device 100 confirms whether the broadcast managed application specified in the AIT can be executed.

  When it is confirmed that the above-described execution is possible, the broadcast receiving apparatus 100 causes the application control unit 161 to display a startup selection screen (FIG. 30 described later) on the video display unit 173 (S1407). The start selection screen is used to allow the user to select the control operation related to the start / end of the non-broadcast application being executed and the broadcast managed application that is requested to be automatically started, in other words, the start target or end target application. FIG. In the seventh embodiment, as the selection of the control operation, it is possible to select whether to continue or end the execution of the non-broadcast application, start the broadcast managed application, or the like on the start selection screen. In other words, it is possible to select whether or not to allow the non-broadcast application and the broadcast managed application to be executed in parallel.

  The user uses the portable information terminal 700 or the remote control of the broadcast receiving device 100, which is his / her own operation means, to perform the control operation related to the activation and termination of the plurality of types of applications on the activation selection screen displayed in S1407. It is selected (S1408). The broadcast receiving apparatus 100 receives the result of the user's selection as an instruction input. If the activation of the broadcast managed application is not selected according to the user's selection result in S1408 (S1409-No), the broadcast receiving apparatus 100 ends the process of FIG. That is, the application control unit 161 does not acquire and start the broadcast managed application specified in the AIT. Execution of the non-broadcast application is continued.

  On the other hand, if the activation of the broadcast managed application is selected (S1409-Yes), the process proceeds to S1410. In S1410, the broadcast receiving device 100 causes the application control unit 161 to terminate the operation of the running non-broadcast application.

  Next, the transmission / reception device 100 transmits a broadcast managed application distribution request to a predetermined service provider server 400 via the LAN communication unit 121 based on the information described in the application acquisition destination information 905 of the AIT (S1412). The service provider server 400 that has received the distribution request in S1412 performs authentication processing of the broadcast receiving apparatus 100 as necessary based on the control of the application management / distribution execution unit 4103, and then stores the authentication processing in the application storage area 4013. The predetermined broadcast managed application is distributed via the LAN communication unit 421 (S1412). Then, the broadcast receiving apparatus 100 activates the broadcast managed application received via the LAN communication unit 121 by the application engine 162 under the control of the application control unit 161 (S1413).

  In the above-described embodiment, when the activation of the broadcast managed application is selected in S1409, control for terminating the non-broadcast application is performed in S1410. The following control is also possible without being limited to this. The broadcast receiving apparatus 100 confirms whether or not the end of the non-broadcast application is selected during or after S1409. The broadcast receiving apparatus 100 executes S1410 if termination of the non-broadcast application is selected according to the user's selection result in this step, and proceeds to S1411 if not selected.

  As a modified example, the processes such as the start confirmation in S1407 to S1410 and the end of the non-broadcast application may be performed after the broadcast managed application is acquired in S1411 to S1412.

[Control example]
FIG. 29 illustrates a control example of reproduction and execution of a broadcast program and a plurality of types of applications corresponding to the processing in FIG. 28 of the seventh embodiment. The horizontal axis indicates time. In the vertical direction, the reproduction of the image of the broadcast program by the broadcast signal of the broadcast wave and the control instruction by the AIT, and (A) the first control, (B) the second control, and (C) the third control are shown in association with each other. (A) The first control indicates (A1) execution of App2, which is a non-broadcast application, and (A2) execution of App1, which is a broadcast managed application. Similarly, (B) the second control indicates (B1) execution of App2 and (B2) execution of App1. (C) The third control indicates (C1) execution of App2 and (C2) execution of App1. Note that, as described above, it is assumed that the start priority of App1 that is a broadcast managed application is higher than that of App2 that is a non-broadcast application.

  First, as an example of reproduction of a broadcast program, broadcast program A is reproduced during a period from time t1 to t3. The program is switched to the broadcast program B from t3 to t4, and the broadcast program B is reproduced during the period from t4 to t6. Along with the switch to the broadcast program B, the AIT instructs to start App1, which is a broadcast managed application that cooperates with the broadcast program B.

  (A) In the case of the first control, App2, which is a non-broadcast application, is activated by a user operation at time t2, for example, as shown in (A1), and is executed from t2. It is assumed that during execution of App2, an instruction to start App1 is issued at t3. At this time, between t3 and t4, continuation of App2 and activation of App1 are selected as user selection by the user selection means 2601. The multiple-application execution control unit 2600 of the broadcast receiving apparatus 100 starts App1 at t4 as shown in (A2) while continuing the execution of App2 according to the user's selection, and changes the display state of the screen in response to this. Control. Thereafter, for example, during a period from t4 to t5, App1 and App2 are executed in parallel, and at t5, App2 is terminated by a user operation or the like. During the period from t5 to t6, the execution of App1 is continued, and at t6, App1 is terminated according to the AIT termination instruction by the AIT.

  (B) In the case of the second control, App2 is executed during the period from t2 to t3 as in (B1), and the termination of App2 and the activation of App1 are selected by the user according to the instruction to activate App1 at t3. Selected. The broadcast receiving apparatus 100 terminates the execution of App2 according to the user's selection, and starts App1 at t4 as shown in (B2). Thereafter, App1 is executed during a period from t4 to t6.

  (C) In the case of the third control, App2 is executed during the period from t2 to t3 as in (C1), and in response to an instruction to start App1 at t3, App2 is continued and App1 is not started as a user selection. Is selected. The broadcast receiving apparatus 100 continues the execution of App2 in accordance with the user's selection, and does not start and execute App1 at t4 as in (C2). Thereafter, App2 is executed during a period from t4 to t5.

[Startup selection screen]
FIG. 30 illustrates an example of the activation selection screen displayed by the processing of S1407 in FIG. 28 according to the seventh embodiment. On this screen, a message box 173g1 is displayed. The message box 173g1 confirms to the user that the non-broadcast application is currently being executed, that the broadcast managed application has been instructed to start and that the start is possible, and that the start is possible. Including the display of a message to the effect. The message box 173g1 of this example includes “Yes” and “No” buttons for allowing the user to select whether or not to activate the message.

  With the message box 173g1 displayed, the user selects “Yes” or “No” using, for example, the cursor key 741ac and the enter key 741ad of the basic screen 741a of the cooperative control application. That is, the user selects “Yes” if he wants to start the broadcast managed application at that time, and selects “No” if he wants to continue the execution of the non-broadcast application. With this screen, the user can easily determine whether or not to start a new broadcast-managed application on the broadcast receiving device 100 that is executing any desired non-broadcast application, according to his / her own convenience and desire at that time. You can choose. The above control is also possible in the case of a general application.

  Instead of the message box 173g1, the above-mentioned icon 173b0 in FIG. 12A or another mark is displayed to prompt a predetermined user operation, and the operation controls the start of the broadcast managed application and the end of the non-broadcast application. May be used. For example, a mark, a message, or the like indicating that there is a request to start the broadcast managed application may be displayed on the OSD in a corner of the screen. If a predetermined user operation is not performed after the display of the icon or the like, the display is deleted.

  FIG. 31 shows an example of another startup selection screen. A message box 173g2 is displayed on the activation selection screen in FIG. The message box 173g2 includes a display of a message or the like for allowing the user to select a control operation regarding activation or termination of a plurality of types of applications including the non-broadcast application and the broadcast managed application. The message box 173g2 includes, as information on specific control options, (1) start the broadcast managed application while executing the non-broadcast application, (2) end the non-broadcast application and start the broadcast managed application, ( 3) Including that the broadcast managed application is not activated.

  With the message box 173g2 displayed, the user selects from the above options using, for example, the color keys 741ae of the basic screen 741a of the cooperative control application. For example, blue corresponds to (1), red corresponds to (2), and yellow corresponds to (3). The screen also allows the user to easily select the termination or activation of each application according to the situation at that time.

  The activation selection screen is not limited to a form displayed when a request is generated, but may be a form displayed at the time of user setting. In this case, the broadcast receiving apparatus 100 displays a user setting menu on the screen of the video display unit 173, for example, similarly to FIG. 25, and displays the control options (1) to (3) and the like on the menu. , Allows the user to make selections. The broadcast receiving device 100 executes control according to the user setting information when a request is generated.

[Execution screen of multiple applications]
In the case of control for ending the non-broadcast application and starting and executing the broadcast managed application, the broadcast receiving device 100 controls the display of the screen of the video display unit 173 in the same manner as in the above-described example. That is, the broadcast receiving apparatus 100 displays, for example, on the screen of the video display unit 173, the execution screen of the non-broadcast application displayed in an area different from the screen of the broadcast program or in a partially overlapping area in the screen of the broadcast program. Then, the execution screen of the broadcast managed application is newly displayed.

  Further, the broadcast receiving apparatus 100 activates the broadcast managed application while the execution of the non-broadcast application is continued, that is, in a case where the both applications are controlled to be executed in parallel, the display of the screen of the video display unit 173 is as follows. May be controlled. The broadcast receiving apparatus 100 appropriately adjusts the size and the display position of the execution screen of one or both applications so that, for example, the execution screen of the non-broadcast application and the execution screen of the broadcast managed application do not entirely overlap each other. In addition, both execution screens may be adjusted so as to overlap in some areas.

  The broadcast receiving apparatus 100 may perform, for example, a process of reducing the size of the execution screen of the currently running non-broadcast application so as not to disturb the display of the execution screen of the newly started broadcast managed application. Conversely, the size of the execution screen of the newly activated broadcast managed application may be reduced so as not to disturb the display of the execution screen of the currently running non-broadcast application. In addition, even if the non-broadcast application is temporarily displayed as an icon, only the execution screen of the broadcast managed application is displayed, and the display of the non-broadcast application execution screen is restored by the user's selection operation of the non-broadcast application icon. Good. Alternatively, both applications may be icons, and the execution screen may be displayed according to the selection of the icon by the user.

  The broadcast receiving apparatus 100 displays, for example, a screen for playing a broadcast program on the screen of the video display unit 173, displays an execution screen of the non-broadcast application on a partial area of the screen for playing a broadcast program, and further displays the screen. An execution screen or the like of a broadcast managed application may be displayed over a part of the execution screen of the non-broadcast application. Further, the broadcast receiving apparatus 100 may divide the entire or partial area of the screen of the video display unit 173 and display the broadcast program and the execution screens of both applications in parallel.

  FIG. 32 shows a screen example of the video display unit 173 corresponding to the control example of the parallel execution of the plurality of applications. In the screen of FIG. 32, the execution screen of the newly activated broadcast managed application is displayed in a partial area 173g3 on the broadcast program display screen 173g. At the same time, the execution screen of the non-broadcast application being executed is reduced or displayed as an icon in a partial area 173g4 within the area 173g3. When the user performs a selection operation on 173g4, the execution screen of the non-broadcast application is displayed in an enlarged manner in area 173g3, and the execution screen of the broadcast managed application is reduced or displayed as an icon in area 173g4. In the area 173g4, a mark or a message indicating that there is an instruction to start the broadcast managed application may be displayed.

  The screen as in the above example allows the user to easily understand and recognize the status of the execution of the broadcast program and the plurality of types of applications.

  FIG. 33 shows another screen example of the video display unit 173 corresponding to the control example of the parallel execution of the plurality of applications. The screen of FIG. 33 includes, in a plurality of divided areas, a broadcast program screen 173g, a non-broadcast application execution screen 173g5, a newly activated broadcast managed application execution screen 173g6, and a start selection screen. An area 173g7 for displaying information is displayed in parallel. In the area 173g7, a mark or a message indicating that there is an instruction to start a broadcast managed application may be displayed, or information of an application list such as the broadcast cooperative app launcher in FIG. 12B may be displayed. Furthermore, when there are two or more non-broadcast applications, general applications, and two or more broadcast managed applications, this screen may display the execution screen of each application in parallel.

[Effects]
As described above, according to the broadcast receiving apparatus 100 of the seventh embodiment, while the non-broadcast application or the general application is being executed by the broadcast receiving apparatus 100, even when a request to start the broadcast managed application is issued by the AIT or the like, various types of plural The activation and termination of the application can be appropriately controlled according to the user's selection. That is, according to the broadcast receiving apparatus 100 of the present embodiment, it is possible to execute a function with higher added value. The user can select and use a non-broadcast application or a broadcast-managed application according to the situation at the time of request generation or the circumstances.

  Which of the control, the modification, the screen display control method, and the like of the seventh embodiment is to be adopted is specified as a specification of the broadcast receiving device 100 or the like, or selected by the user for the broadcast receiving device 100 or the like. Enable settings.

  The following is a possible modification of the seventh embodiment. As a first modification, after the processing up to S1406 in FIG. 28, the end of the non-broadcast application and the start of the broadcast managed application in S1410 to S1413 are automatically performed without confirming the user selection in S1407 to S1408. It may be performed. Similarly, after the processing up to S1406, the control may be performed so that the broadcast managed application is automatically started while the non-broadcast application is continued without confirming the user selection. Similarly, during execution of a non-broadcast application or a general application, control may be performed so as not to automatically start the broadcast managed application without confirming user selection. In the case of this modification, the user has less trouble in operation.

  As a second modified example, not only the confirmation of the instruction input of the user selection on the activation confirmation screen but also the user setting on the broadcast receiving device 100 or the portable information terminal 700 using the user setting in the same manner as in the sixth embodiment described above. May be implemented. For example, the user can select and set whether or not to activate a broadcast managed application during execution of a non-broadcast application or a general application by user setting information based on the above-described function setting menu or the like. The broadcast receiving device 100 stores the set value in the storage unit 110. The broadcast receiving apparatus 100 refers to and confirms the contents of the user setting information of the broadcast receiving apparatus 100 when the start of the broadcast managed application is requested during the execution of the non-broadcast application or the like, for example, in the processing of S1407 to S1409. . The broadcast receiving apparatus 100 determines and determines the control such as the activation according to the contents. In the case of this modification, the user can appropriately change the user settings according to his / her convenience and use a plurality of types of broadcast cooperation applications.

  The same applies to the case where the user setting of the portable information terminal 700 is used. As in the sixth embodiment, the activation and termination of the plurality of types of applications can be flexibly controlled according to the presence or absence of the associated portable information terminal 700 or the user setting for each associated portable information terminal 700.

  As another modified example, the broadcast receiving apparatus 100 displays information indicating that the non-broadcast application has been terminated halfway and the broadcast managed application has been activated, as a control example related to the (B) second control in FIG. 29 described above. Then, after terminating the broadcast managed application, the non-broadcast application that has been terminated on the way may be activated and executed again automatically or by a predetermined user operation. In the case of this modification, the user can easily return to using the non-broadcast application.

  As another modification, as a control example related to (C) the third control in FIG. 29, the broadcast receiving apparatus 100 transmits the broadcast managed application according to the user's selection at the time of the request to start the broadcast managed application. Hold without launching and continue running non-broadcast apps. Thereafter, the broadcast receiving apparatus 100 activates the reserved broadcast managed application, for example, after termination of the non-broadcast application. As an example of the screen display control in this case, a message indicating that there is a request to start the broadcast managed application, a message indicating that the start of the broadcast managed application is suspended, a mark, or the like is displayed in a corner of the execution screen of the non-broadcast application. This prompts the user to end the non-broadcast application and activate the broadcast managed application. In the case of this modification, the user can start using the broadcast managed application at a convenient timing.

  Hereinafter, an eighth embodiment of the present invention will be described. The configuration, effects, and the like in this embodiment are the same as those in the first embodiment unless otherwise specified. Therefore, in the following, differences between the present embodiment and the first embodiment will be mainly described, and description of common points will be omitted as much as possible to avoid duplication.

  The broadcast receiving apparatus 100 according to the eighth embodiment has a function of suitably controlling the restart according to a user's selection when restarting an application that has been once ended. Automatic restarting of the broadcast cooperative app is technically possible, but may be undesirable in control or inconvenient for the user. On the other hand, the broadcast receiving apparatus 100 according to the eighth embodiment enables the restart of the broadcast cooperation application, and controls the restart according to the user's selection of whether or not the restart is permitted. Thereby, even in the case of termination due to an erroneous operation by the user, it is possible to respond by restarting according to the user's selection.

  The broadcast receiving apparatus 100 according to the eighth embodiment is configured as follows when the application instructed to perform priority and automatic activation by the AIT or the like is terminated by a user operation or the like, and when the activation instruction by the AIT is continued. Control. That is, (1) the broadcast receiving apparatus 100 controls the restart according to the user's selection, that is, according to the input of the instruction or the confirmation of the user setting. (2) The broadcast receiving apparatus 100 displays information such as an icon for allowing the user to select whether or not to restart the application on the screen, and only when the user has requested the information by selecting the information, Restart the application.

  FIG. 34 illustrates a system configuration including the broadcast receiving device 100 according to the eighth embodiment. The broadcast receiving device 100 includes an application restart control unit 3400. The application restart control unit 3400 includes a user selection unit 3401 and a storage unit 3402. The user selection unit 3401 accepts a selection operation related to an operation of controlling restart of an application based on an operation of a user of the broadcast receiving device 100 or the portable information terminal 700. The user selection unit 3401 is realized by inputting an instruction on a screen of the broadcast receiving apparatus 100 or the screen of the portable information terminal 700 or setting a user, similarly to the sixth embodiment.

  The application restart control unit 3400 stores information on the execution and the status of the application in the storage unit 3402 as the application execution information 3411. The application execution information 3411 includes cache data that holds information on the terminated application. The application restart control unit 3400 controls whether or not to restart the application according to the user selection by the user selection unit 3401 when and when a situation related to the restart of the broadcast managed application occurs. . The application restart control unit 3400 uses the application execution information 3411 when restarting the application.

  FIG. 35 shows an example of reproduction of a broadcast program by a broadcast signal, instruction by an AIT, execution and control of a broadcast managed application, user operation and user selection, and the like on the time axis in the eighth embodiment.

  The broadcast managed application, which is a kind of the broadcast cooperative application used in the broadcast communication cooperative system of the present embodiment, operates such as start / end based on information such as the AIT application control code 903 included in the broadcast signal. Controlled. The control of the operation of the broadcast managed application may be performed based on a user's instruction operation or the like.

  When the operation of starting a broadcast managed application associated with a broadcast program is controlled by the AIT or the like, information such as the application control code 903 of the AIT for instructing the start is at least included in the broadcast signal at the start of the broadcast program. include. Further, it is necessary that the information be included in the broadcast signal not only at the start of the broadcast program but also continuously during the broadcast of the broadcast program. The reason is that the user does not always watch the broadcast program from the beginning of the broadcast program, and may start viewing the broadcast program from the middle of the broadcast program. When a broadcast program is reproduced from the middle, the broadcast managed application cannot be started unless the broadcast signal contains the above information.

  Therefore, information such as AIT is continuously transmitted during the period from the beginning to the end of the broadcasting of the broadcast program. The information may be transmitted periodically, for example, once every few seconds. For example, the broadcast receiving apparatus 100 periodically refers to and acquires information such as AIT included in the broadcast signal and checks whether the information content is updated. Thereby, even when the user watches the broadcast program from the middle, the activation of the broadcast managed application can be controlled.

  On the other hand, the information such as the application control code 903 for instructing the end of the execution of the broadcast managed application should be included in the broadcast signal at least when the application is to be ended, for example, at the end of the broadcast program. What should I do? Further, for example, when the broadcast managed application is to be terminated at an arbitrary timing during the broadcast of a broadcast program, for example, at a time point designated by a broadcast station, information of a termination instruction may be included in the broadcast signal at that timing. Upon receiving the end instruction, the broadcast receiving device 100 ends the execution of the broadcast managed application.

  When the broadcast managed application is terminated at an arbitrary timing during the broadcast of the broadcast program, for example, at a time based on a user operation, the following control operation may be performed. For example, based on a change of a frequency channel by a user using the portable information terminal 700 or a remote controller, that is, an operation of selecting a channel or a program to be reproduced, or an operation of an instruction to end an application, the broadcast receiving apparatus 100 The execution of is terminated.

  The example of the AIT in FIG. 35 shows an example in which the instruction information is continuously and regularly included during the broadcast of the broadcast program as described above. For example, there is a broadcast managed application M1 that cooperates with the broadcast program A. The AIT is regularly distributed, including the beginning and end, during the time period from the time t1 to the time t3 when the broadcast program A is being broadcast. The first AIT at t1 includes at least an instruction to automatically start the broadcast managed application M1. The last AIT of t3 includes at least an instruction to automatically end the broadcast managed application M1. Thereby, the broadcast managed application M1 is automatically executed during the period from t1 to t3 as shown in FIG. The AIT is similarly distributed between t1 and t3, as at t2. The same applies to the broadcast program B and the broadcast managed application M2.

  The broadcast managed application may be terminated based on a user's instruction operation at a timing during the broadcast of the broadcast program. Also in this case, while the broadcasting of the broadcast program is continuing, there may be a case where PMT, AIT, or the like included in the broadcast signal continuously instructs automatic activation giving priority to the application.

  FIG. 35B shows an example in which the broadcast managed application M2 is activated in the middle of the broadcast program B and the broadcast managed application M2 is terminated in the middle of the broadcast program B. It is assumed that the broadcast program B is reproduced by the user operation of (c) at time t5, for example, by changing the frequency channel (ch). Thereafter, the broadcast managed application M2 is activated, for example, by an instruction to activate the broadcast managed application M2 by the AIT at a regular time t6. Further, it is assumed that, by the user operation (c), for example, at time t7, an instruction to change the frequency channel (ch) or to terminate the broadcast managed application M2 is issued. Thereby, the broadcast managed application M2 is terminated.

  However, when the broadcast managed application is terminated by the user's instruction operation, it is obviously not preferable that the same broadcast managed application is automatically restarted based on the description of the PMT, the AIT, or the like. For example, once the application is terminated, the AIT is periodically checked immediately, and the application is automatically restarted in accordance with an instruction to automatically start the AIT. From the user's point of view, the app is immediately restarted despite the instruction to close the app. Therefore, a configuration that disables the automatic restart of the same broadcast managed application as described above is conceivable.

  On the other hand, the possibility that the instruction operation for ending the broadcast managed application is an erroneous operation by the user should be considered. In consideration of this possibility, it is not preferable to disable automatic restart of the same broadcast managed application. From the user's point of view, it is inconvenient to restart or restore immediately if the application is terminated by mistake.

  The broadcast receiving apparatus 100 according to the eighth embodiment has a function of performing control in consideration of restart of the application. In the eighth embodiment, the execution of the broadcast managed application is terminated based on a user's instruction operation or the like at an arbitrary timing in the middle of the broadcast program, and the priority of the same application is given by information such as AIT included in the broadcast wave. An example of control of restart of the broadcast managed application of the broadcast receiving apparatus 100 when automatic start is continuously instructed will be described.

  In (d) of FIG. 35, the broadcast managed application M2 is terminated in the middle of the broadcast program B as in (b). However, since the start instruction is continued at the AIT at time t8, Shows that the broadcast managed application M2 is restarted immediately.

  FIGS. 35E to 35G show control examples of the broadcast receiving apparatus 100 according to the eighth embodiment. In the eighth embodiment, in the case of (d), the user selection of (e) is confirmed. Accordingly, in the first control of (f), the broadcast managed application M2 is suppressed from being restarted and re-executed. In the second control (g), the broadcast managed application M2 is controlled so as to be restarted and re-executed. The user selection in (e) is, for example, inputting an instruction on a screen or confirming user setting information.

[Operation sequence when restarting broadcast managed application]
FIG. 36 illustrates an example of an operation sequence of control including a process of restarting the broadcast managed application in the broadcast receiving device 100 according to the eighth embodiment. FIG. 36 shows a flow of a series of control operations when the broadcast managed application is specified and instructed to be started with priority. The broadcast receiving apparatus 100 terminates the broadcast managed application automatically started based on the AIT of the broadcast signal when the user starts viewing the broadcast program in response to a user's instruction operation. Further, the broadcast receiving apparatus 100 appropriately checks the PMT and the AIT, and controls whether or not to restart the once-terminated broadcast managed application according to the user's selection.

  In FIG. 36, the broadcast receiving apparatus 100 obtains a TS by performing tuning processing of a frequency channel desired by the user by the tuner / demodulation unit 131. Then, in S1500, the broadcast receiving apparatus 100 performs, for example, the same processing as S101 to S108 in FIG. 7A described above. That is, the broadcast receiving apparatus 100 confirms the activation priority from the PMT, confirms an instruction such as automatic activation by the application control code of the AIT, confirms an executable state from the application profile, and determines a predetermined state from the provider server or the like as appropriate. Get a broadcast managed app that is a broadcast cooperative app. The broadcast receiving apparatus 100 activates a broadcast managed application by the application engine 162 under the control of the application control unit 161.

  After the processing in S1500, in S1509, the broadcast receiving apparatus 100 causes the application control unit 161 to use the information on the started broadcast managed application and the status as the application execution information 3411 in the temporary storage area of the RAM 104 (the storage unit in FIG. 34). 3402) to temporarily store, in other words, cache. The processing of S1509 may be performed according to the above-described AIT cache information 908.

  The application execution information 3411 includes information such as PMT and AIT, data of an HTML document that constitutes the broadcast managed application, and attributes such as a broadcast program name and a service ID (frequency channel) related to the application, which are acquired in the process of S1500. , Etc. It should be noted that these pieces of information are referred to as the application execution information 3411 for the purpose of explanation, but individual information may be managed.

  Here, in FIG. 36, it is assumed that the user instructs the end of the broadcast managed application using the portable information terminal 700 or a remote controller at any desired timing during the broadcast program without waiting for the end of the broadcast program. (S1510). This corresponds to the user operation time t7 in FIG. 35 (c). Then, the broadcast receiving device 100 ends the execution of the broadcast managed application by the application engine 162 (S1511).

  Upon terminating the broadcast managed application in S1511, the broadcast receiving apparatus 100 obtains a PMT data sequence again by the main control unit 101 (S1512), and obtains an AIT data sequence by the application control unit 161 (S1513). The acquisition of the information in S1512 and S1513 may be one of continuous and regular execution during the broadcast of the broadcast program as shown in FIG. 35, or the broadcast receiving apparatus 100 may A process of acquiring and referring to the information may be performed. The PMT contains information indicating the AIT, and here, both the PMT and the AIT are referred to and acquired.

  Next, in the processing of S1514, the broadcast receiving apparatus 100 checks whether the AIT information of S1513 instructs the same application activation as that at the time of the temporary storage in S1509, for example, the automatic activation giving priority to the broadcast managed application. I do. In other words, in S1514, it is checked whether execution of the same HTML document has been instructed and whether the display content of the broadcast managed application has been updated. In S1514, when the information content of the AIT in S1513 is the same as the information content of the AIT in the application execution information 3411 at the time of temporary storage in S1509, that is, the activation of the same application and the execution of the same document are instructed, and the display content is changed. If it has not been updated (Yes), the process proceeds to S1516. In step S1514, when the information content of the AIT in S1513 is different from the information content of the AIT in the application execution information 3411 at the time of temporary storage in S1509, that is, the activation of a different application or the execution of a different document is instructed, and the display content is updated. If so (No), the process proceeds to S1515.

  For example, while the broadcast program is being broadcast, there is a possibility that the information content of the AIT included in the broadcast signal is partially changed. For example, there is a case where a description of a link of a transitionable HTML document in a plurality of HTML documents constituting the same broadcast cooperation application is changed. Alternatively, there is a case where the description of the link is changed so that transition to an HTML document of a different application is possible. In S1514, the determination is made including the presence or absence of such a change.

  When proceeding to S1515, the broadcast receiving device 100 performs a suppression so as not to restart the broadcast managed application terminated in S1511. In this case, the broadcast receiving apparatus 100 performs a process such as starting a predetermined broadcast managed application or updating display contents again in FIG. 7A based on the changed PMT and AIT information contents acquired in S1512 and S1513. What is necessary is just to perform it similarly to the process of S101-S108. Then, the present process of FIG. 36 ends.

  FIG. 37 shows a restart suppression screen which is an example of a screen displayed at the time of S1515. The broadcast receiving device 100 may display a screen and information as shown in FIG. 37 at the time of S1515. The screen of FIG. 37 displays a predetermined mark 173h1 indicating that the restart of the broadcast managed application has been suppressed, a message, or the like on a screen 173h of the broadcast program, for example, in a corner of the screen. Thereby, the user can recognize the situation in which the restart of the application is suppressed.

  On the other hand, when proceeding to S1516, the broadcast receiving apparatus 100 performs control for restarting the broadcast managed application terminated in S1511. In S1516, the broadcast receiving apparatus 100 displays information for restarting the broadcast managed application ended in S1511 in response to a user's selection operation on the screen of the video display unit 173.

  FIG. 38 shows a restart confirmation screen which is an example of the screen displayed in S1516. This screen displays a message box 173h2 for confirming restart on the screen 173h of the broadcast program. Alternatively, this screen may display a restart icon 173h3 at a corner or the like in the screen. The broadcast receiving apparatus 100 accepts a user's selection operation on the information on this screen, in other words, an instruction input operation for selecting whether or not to restart. The message box 173h2 includes a message for confirming whether or not to restart the broadcast managed application, and “Yes” and “No” buttons. The broadcast receiving device 100 restarts the application in response to the operation of selecting “Yes”.

  The icon 173h3 is an icon indicating a predetermined broadcast managed application. The broadcast receiving device 100 restarts the application by an operation of selecting the icon 173h3. The icon 173h3 may be the same as the icon 173b0 that allows the user to recognize the broadcast cooperative app that can be started as shown in FIG. 12A. Further, the broadcast receiving apparatus 100 automatically deletes the display of the message box 173h2 and the icon 173h3 after a predetermined time has elapsed since the display of the message box 173h2 and the icon 173h3, and does not restart in this case. Since the display of the confirmation information is continued for a predetermined time, the application can be restarted by the operation of the user selecting the icon 173h3 remaining in the screen. The user can easily select whether or not to restart the application according to his / her convenience at that time on the screen.

  On the screen of S1516 in FIG. 36, in S1517, the user receives an operation of selecting the restart icon 173h3 or the like using the portable information terminal 700, the remote controller, or the like as the operation means. Here, for example, it is assumed that the user has selected the icon 173h3 for restarting the screen from the portable information terminal 700. The same applies to the selection of the "Yes" button in the message box 173h2. The broadcast receiving apparatus 100 internally instructs the restart of the broadcast managed application terminated in S1511 according to the selection of the user.

  Upon restarting the broadcast managed application, the broadcast receiving device 100 first reads the HTML document data constituting the application in the application execution information 3411 temporarily stored in S1509 by the application control unit 161 in S1518. Further, in S1519, the broadcast receiving apparatus 100 executes the HTML document by the application engine 162 under the control of the application control unit 161. As a result, the broadcast managed application terminated in S1511 is restarted.

  If the user does not want to restart the broadcast managed application instructed in S1510 and ended in S1511, the user inputs an instruction not to restart using the operation unit in S1517, or leaves the instruction without inputting the instruction. do it. For example, there is a selection of a "No" button in the message box 173h2, a press of the above-mentioned return key 741ab, and the like. As a result, the broadcast receiving apparatus 100 does not internally generate a restart instruction, and also erases the display of the restart confirmation screen.

  As described above, according to the broadcast receiving apparatus 100 of the eighth embodiment, the broadcast managed application is terminated by a user operation or the like in the middle of a broadcast program, and the priority automatic start of the same application is continued based on information such as AIT of a broadcast wave. Even when the user is instructed, the restart of the application can be suitably controlled in accordance with the user's selection. The user can control whether or not to restart the application with a simple operation. Since the user can immediately restart the application even in the case of an erroneous operation, the convenience is high. That is, according to the broadcast receiving apparatus 100 of the present embodiment, it is possible to execute a function with higher added value.

  As a modification of the eighth embodiment, the process of restarting the application in S1516 to S1519 may be executed in accordance with confirmation of the user setting information in the broadcast receiving device 100 or the portable information terminal 700, as in the sixth embodiment. For example, the broadcast receiving apparatus 100 provides a screen for user setting regarding whether or not the restart of the application is permitted, and sets a setting value based on a user operation in the storage unit 110 (the storage unit 710 in the case of the portable information terminal 700). Store in advance. The broadcast receiving apparatus 100 refers to the setting value of the broadcast receiving apparatus 100 or the portable information terminal 700 and confirms it instead of the restart confirmation screen of S1516. The broadcast receiving device 100 restarts the application when the restart is permitted by the setting value.

  As a modification of the eighth embodiment, the broadcast receiving apparatus 100 may perform a process of adjusting and controlling the transparency of the display of the broadcast managed application on the screen instead of the process of terminating the broadcast managed application in S1511. The display at the time of execution of the broadcast managed application is set to 0% transparency, and the display at the end of the broadcast managed application is set to 100% transmittance. When terminating the application in S1511, the broadcast receiving device 100 maintains the application without terminating it, and changes the transparency of the display of the execution screen of the application on the screen to 100% so that the user cannot see the application. I do. Further, when the application is restarted in S1516 to S1517, the broadcast receiving device 100 restores the transparency of the display of the application on the screen to the original state of 0% so that the user can see the application. In the case of this modification, in the processing of S1518 to S1519, there is no need to read and execute the HTML document of the application execution information 3411 in the temporary storage area, and the processing load is low. The transmittance may be a value other than 0% and 100%.

  Hereinafter, a ninth embodiment of the present invention will be described. Note that the configuration, effects, and the like in this embodiment are the same as those in Embodiment 8 unless otherwise specified. Therefore, in the following, differences between the present embodiment and the eighth embodiment will be mainly described, and descriptions of common points will be omitted as much as possible to avoid duplication.

  In the broadcast managed application used in the broadcast / communication cooperation system according to the ninth embodiment, the operation such as start / end is controlled not only based on information such as AIT included in the broadcast signal, but also appropriately included in the broadcast signal. Event operation such as page update by an event message to be performed is possible. In this embodiment, the page update means that part or all of information such as characters and images constituting the application screen displayed on the display unit 173 by the execution of the broadcast managed application is changed, or Transition from the HTML document corresponding to the screen to the HTML document corresponding to another application screen linked to the screen. The page update is also illustrated as a transition between applications and between HTML documents in FIG. 27 described above. The HTML document corresponds to the page. Updating corresponds to a change in the HTML document constituting the application.

  When priority automatic start of the broadcast managed application is continuously instructed by the AIT or the like included in the broadcast wave, an event message for controlling the event operation of the application is continuously included in the broadcast wave as necessary. Will be. Even when the user terminates the broadcast managed application by his / her own judgment, a page update or the like may be performed based on an event message or the like of the broadcast wave. In this case, before and after the end, the content of the execution and display of the application is changed by the page update.

  In this case, consideration should be given to the possibility that the user wants to restart the broadcast managed application once terminated. In other words, there is a possibility that the user wants to browse the information of the page newly provided by the page update. The broadcast receiving apparatus 100 according to the ninth embodiment has a function of appropriately controlling the restart of the application in consideration of the case and the situation of the page update or the like.

[Operation sequence when restarting broadcast managed application]
FIG. 39 illustrates an example of an operation sequence of control of restart of the broadcast managed application in the case where the broadcast managed application is instructed to start preferentially in the broadcast receiving device 100 according to the ninth embodiment. In FIG. 39, the broadcast receiving apparatus 100 terminates the broadcast managed application automatically started at the start of viewing the broadcast program by a user's instruction operation. Furthermore, the broadcast receiving apparatus 100 checks the AIT or the like as appropriate and, if the information content is not updated, responds to the event message newly acquired from the broadcast wave and according to the user's selection, and terminates the terminated broadcast. Controls whether to restart the managed app.

  In FIG. 39, the processing in S1600 to S1615 is the same as the processing in S1500 to S1515 in FIG. The broadcast wave appropriately includes an event message. In S1600, the broadcast receiving apparatus 100 starts a predetermined broadcast managed application by performing the same processing as in S101 to S108 in FIG. 7A. After S1600, the broadcast receiving apparatus 100 stores information about the started broadcast managed application in the temporary storage area as application execution information 3411 in S1609.

  As an example, up to S1609, a portion from a first page (for example, HTML11 of App1 in FIG. 27) to a third page (for example, HTML13) in a certain broadcast managed application is executed through transition between pages and is viewed by the user. I do. In S1609, the contents of the execution and browsing are cached as the application execution information 3411.

  In step S1610, the user instructs to end the broadcast managed application at a timing during the broadcast program. In S1611, the broadcast receiving device 100 ends the execution of the broadcast managed application. In S1612, the broadcast receiving apparatus 100 acquires a PMT data sequence again, and acquires an AIT data sequence in S1613.

  Next, in S1614, if the AIT information acquired in S1613 is not the same as the AIT information content of the application execution information 3411 temporarily stored in S1609 (No), the process proceeds to S1615. In this case, the broadcast managed application terminated in S1611 is not restarted. In S1615, a predetermined broadcast managed application activation process is performed again using the updated PMT and AIT acquired in S1612 and S1613.

  On the other hand, if the AIT information acquired in S1613 is the same as the AIT information content of the application execution information 3411 temporarily stored in S1609 (Yes), the process advances to S1616 to restart the broadcast managed application terminated in S1611. Control is performed. After S1616, the broadcast receiving apparatus 100 according to the ninth embodiment monitors the event message included in the broadcast wave until the frequency channel is changed or information such as PMT and AIT included in the broadcast wave is updated. And acquisition. When the frequency channel is changed or information such as PMT and AIT included in the broadcast wave is updated, the broadcast receiving apparatus 100 shifts the processing to S1615 and performs the same processing. The event message may be periodically delivered, for example, like the AIT. The broadcast receiving device 100 may acquire the event message, for example, periodically.

  As an example, in S1616, it is assumed that transition and display to a portion after the fourth page (HTML14 of App1 in FIG. 27) of the broadcast managed application are instructed as page update by an event. The user has not browsed the portion after the fourth page.

  In S1616, the broadcast receiving device 100 acquires the event message separated by the first separation unit 132 by the application control unit 161. Next, the broadcast receiving device 100 analyzes the acquired event message and determines the analysis result. In S1617, the broadcast receiving device 100 confirms whether the event message acquired in S1616 instructs the broadcast managed application terminated in S1611 to update a page or the like. If the event is not an instruction to update a page or the like in S1617 (No), the process of FIG. 39 ends. That is, the broadcast managed application terminated in S1611 is not restarted.

  On the other hand, if it is determined in step S1617 that the event is an instruction to update a page or the like (Yes), the process advances to step S1618 to perform control for restarting the broadcast managed application terminated in step S1611. In S1618, the broadcast receiving device 100 reads the HTML document of the application execution information 3411 temporarily stored in S1609. The document is before the page is updated. Further, in S1619, the broadcast receiving apparatus 100 transmits the event message acquired in S1616 to the application engine 162, and the application engine 162 executes the HTML document read in S1618 based on the control of the application control unit 161. In the process of S1619, the broadcast receiving device 100 reflects the page update by applying the instruction content of the event message of S1616 to the HTML document. As a result, the broadcast managed application terminated in step S1611 is restarted. The content displayed on the screen of the application by the restart is a state after the page is updated.

  As an example, as for the display content of the screen of the broadcast managed application after the restart, the portion after the fourth page is displayed. The user can browse the portion after the fourth page that has not been browsed before the end after restarting.

  At the time of the restart, the broadcast receiving apparatus 100 may perform control to automatically transition to and display a new page (for example, the fourth page) after the page update. At this time, the broadcast receiving apparatus 100 may display a message indicating that a page update has occurred, a message indicating that the page has changed to a new page, or the like on the screen. In this case, the user has less trouble of operation such as transition between pages.

  Also, at the time of the restart, the broadcast receiving apparatus 100 controls the display so as to restore the page before the page update (for example, the third page), displays a message for confirming the page update on the screen, etc. According to the operation, control may be performed so as to transition to a new page (for example, the fourth page) after the page is updated. In this case, the user can easily recognize the status of the page update.

  FIG. 40 shows an update confirmation screen as an example of a screen when the user confirms the restart in the case of the page update and restarts according to the user selection. For example, when the event is a page update in S1617, the broadcast receiving apparatus 100 displays a screen as shown in FIG. This screen displays a message box 173h4. The message box 173h4 includes a message indicating that the page content of the broadcast managed application has been updated, and a button for selecting whether or not to restart. When restart is selected on this screen, the broadcast receiving device 100 restarts the application. With this screen, the user can easily recognize the situation, restart the application according to the situation at that time, and browse the updated page content.

  As described above, according to the broadcast receiving apparatus 100 of the ninth embodiment, for the broadcast managed application that has been once ended, the broadcast managed application of the broadcast managed Restart can be suitably controlled. That is, according to the broadcast receiving apparatus 100 of the present embodiment, it is possible to execute a function with higher added value.

  As a modification of the ninth embodiment, the broadcast receiving apparatus 100 performs the processes of S1616 to S1619, that is, the process of restarting the application reflecting the page update by the event message, similarly to the sixth embodiment. It may be executed according to the confirmation of the user setting information in the portable information terminal 700. For example, the broadcast receiving apparatus 100 provides a screen for user setting regarding whether or not the restart of the application is permitted and a restart in the case of a page update due to an event, and stores a setting value based on a user operation. At the time of acquiring the event message in S1616, the broadcast receiving apparatus 100 checks the above set values and determines whether or not to restart.
