Description

  The present invention relates to a broadcasting / communication cooperation system, and more particularly to a Web server, a viewer service providing program, a receiver program, and a service providing system.

  FIG. 7 is a schematic diagram showing a configuration of a conventional broadcasting / communication cooperation system. This broadcasting / communication cooperation system 901 includes a digital broadcasting receiving device 3, a digital broadcasting transmitting device 905, and a Web server 906. Conventionally, a broadcasting station (broadcaster) serves as a service provider and provides various services via a communication network N to viewers (members) registered in advance in a predetermined member site. A service providing system 902 for providing services to viewers (members) includes a digital broadcast transmission device 905 and a Web server 906.

  Broadcasters are working to improve services so that viewers can continuously watch broadcast programs such as dramas. As such a viewer service, a “drama viewing stamp rally” has been developed for members who viewed a broadcast drama program (see Non-Patent Document 1). With this stamp rally mechanism, viewers can receive points that can be used as members each time they press a stamp by pressing a stamp on the stamp book on the communication content as a recorded recording during the drama broadcast. If you press the stamps for all broadcasts, you will receive a privilege that you can apply for a souvenir or a studio tour.

  As shown in FIGS. 8 (a) and 8 (c), a program-linked content 811 is broadcast as a data broadcast in a drama developing a stamp rally. When the program linked content 811 is displayed on the screen, a broadcast drama (program content) is displayed on the broadcast program content area 812. According to the program-linked content 811, information such as a drama outline can be viewed. Various buttons that can be operated by a remote controller by the user are displayed on the program-linked content 811. For example, as shown in FIG. 8A, a yellow button 813 for returning from the current page to the top page of the data broadcasting content, and a green button for proceeding to the data broadcasting content page describing more detailed information than the current page. Button 814 is displayed. In addition, in the case of the digital broadcast receiving device 3a connected to the communication network N as shown in FIG. 7, for example, a stamp rally button 815 as a red button for proceeding to the communication content page in the data broadcast on the program linked content 811. Is displayed.

When a viewer participating in the stamp rally presses the stamp rally button 815 shown in FIG. 8A, the screen display of the digital broadcast receiving device 3a is displayed as shown in FIG.
The program linked content 811 makes a transition to the stamp rally content 821. This stamp rally content 821 is communication content distributed from a Web server 906 that provides a viewer service that is registered in advance as a member by the viewer. During the transition to the stamp rally content 821, the digital broadcast receiving device 3a communicates with the Web server 906 and logs into the member site.

  The program-linked content 811 ends with the end of the program, but the viewer can see his / her stamp book in the stamp rally content 821 even when the program is not being broadcast. However, the stamp can only be pressed while the program content is being broadcast.

  When the user presses a stamp during the drama broadcast, the stamp rally content 821 transmits stamp stamp information to the Web server 906 that provides the member site (step S701: see FIG. 7). Then, the Web server 906 records the stamp stamp information in the stamp database associated with the member information (step S702), and returns the stamp stamp result to the digital broadcast receiving device 3a (step S703). Then, the digital broadcast receiving device 3a displays the stamp stamp result on the communication content page in the data broadcast (step S704). Thereby, the viewer can confirm that the stamp is accumulated on the page screen of the communication content.

  Regarding user registration, Patent Document 1 discloses a technique in which a broadcasting station transmits a program for displaying a two-dimensional code by data broadcasting, and a viewer performs user registration using the two-dimensional code. ing. According to this method, it is possible to register a user at a predetermined member site by reading a two-dimensional code displayed on the screen of the digital broadcast receiving device 3 with a portable terminal and accessing a predetermined URL (Uniform Resource Locator). .

  On the other hand, viewers of digital broadcasting are not forced to prepare an environment for connecting to the Internet, and the present situation is that digital broadcasting receiving devices 3a and 3b are mixed. For example, when a viewer who uses the digital broadcast receiving device 3a at home receives a stamp rally service and views the drama with the digital broadcast receiving device 3b not connected to the communication network N outside the home, Could not press the stamp. In such a case, it has not been possible to obtain a privilege that requires the stamps of all broadcast times to be pressed within a certain period.

  It is also possible to display a two-dimensional code indicating stamp information on the screen of the digital broadcast receiving apparatus 3b not connected to the communication network N, read the two-dimensional code, and send it to the Web server 906. However, since everyone has issued the same password and the stamp information is a predetermined URL, there is a risk of URL spreading that the URL information will be disclosed on a bulletin board on the Internet. If the URL information is made public, a member who has not actually watched the drama will be able to perform an illegal act such as receiving a privilege of the stamp rally. In such a case, a viewer who makes an effort to continuously view the viewer feels uncomfortable feelings. Therefore, a mechanism for preventing such fraud is required.

  The present invention has been made in view of the above-described problems.

[Digital broadcasting transmitter]
The digital broadcast transmission device 5 broadcasts program content provided by the viewer service, and broadcasts program-linked content provided by data broadcasting in conjunction with the program content being broadcast.

  When the broadcast service request information is acquired by the digital broadcast receiving device 3 during broadcasting, the program-linked content transitions to the viewing record information issuance content when the digital broadcast receiving device 3 is not connected to the communication network N. To do.

  The viewing record information issue content is content that can be changed from program-linked content in data broadcasting, and is independent content that is not linked to the program being broadcast. In addition, the viewing record information issuance content displays a two-dimensional code and a guidance sentence recommending the reading on the screen of the digital broadcast receiving apparatus 3. This viewing record information issue content is displayed on the screen of the digital broadcast receiving device 3b not connected to the communication network N, and is not displayed on the screen of the digital broadcast receiving device 3a connected to the communication network N.

  The two-dimensional code displayed by the viewing record information issuance content is generated from text information obtained by concatenating the character string of the viewing secret information after the character string of the URL of the Web server 6. The viewing secret information is information indicating that the viewer has watched the program content during broadcasting. The contents of the viewing secret information include, for example, time information for viewing the data broadcast, program identification information (program ID) of the program being broadcast, and device identification information (receiver ID) of the digital broadcast receiving device 3 that is receiving the broadcast. Is included.

  Here, the time information for viewing the data broadcast is, for example, that the program-linked content is first displayed by pressing the d button on the remote control when the corresponding program content is displayed during broadcasting in the digital broadcast receiving device 3. It can be time information. The program ID is information sent by data broadcasting. The receiver ID is written in the security module of the digital broadcast receiver 3.

You may make it transmit to. The broadcast control means 32 performs various controls such as content scrambling and key information encryption corresponding to the digital broadcast conditional access system, although detailed explanation is omitted.

  The broadcast transmission means 33 multiplexes the program content output from the broadcast control means 32, data of data broadcast, etc., and transmits (distributes) them in the data carousel.

[Digital broadcast receiver]
The digital broadcast receiving apparatus 3 receives program content and data broadcast by the broadcast wave W or the like. Here, the digital broadcast receiving apparatus 3 includes broadcast receiving means 41, user operation means 42, display means 43, content storage means 44, program storage means 45, and reception control means 46. The digital broadcast receiving apparatus 3 is capable of receiving digital broadcasts by mounting the individual information storage card 47 that is a security module. The individual information storage card 47 is, for example, a B-CAS card. The digital broadcast receiving device 3 may be connected to the communication network N (digital broadcast receiving device 3a: FIG. 1) or may not be connected (digital broadcast receiving device 3b: FIG. 1).

The broadcast receiving means 41 is composed of a tuner or the like that receives a digital broadcast transmitted from the digital broadcast transmitting apparatus 5, and outputs a digital signal received when the individual information storage card 47 is attached to the reception control means 46.
The user operation unit 42 outputs a command designated by a user operation to the reception control unit 46, and is, for example, a remote control device.
The display means 43 displays the digital broadcast program and data broadcast decoded as the processing result of the reception control means 46 on the screen, and is, for example, an LCD (Liquid Crystal Display).

  The content storage unit 44 stores content such as a digital broadcast program received by the broadcast receiving unit 41, and includes a hard disk or the like.

  The program storage unit 45 stores an operation program of the reception control unit 46 and the processing result thereof, and is configured by a memory, a hard disk, or the like. The program storage means 45 includes, for example, an NVRAM (Non-volatile Random Access Memory) which is a non-volatile memory storing information such as the postal code of the area where the user lives and the prefecture.

  The reception control means 46 controls the reproduction / display of the digital signal received by the broadcast receiving means 41. Here, the reception control unit 46 is a content reproduction control unit 461, a display control unit 462, a service request reception unit 463, a communication content screen transition unit 464, a broadcast content screen transition unit 465, and a two-dimensional code generation unit. 466, a reissue request accepting unit 467, an elapsed time determining unit 468, and a reissue information generating unit 469.

  The content reproduction control means 461 performs control to reproduce the content by separating the encryption key information and content from the received multiplexed digital signal, decrypting the key information, and descrambling the content. is there.

  The display control unit 462 displays the content reproduced by the content reproduction control unit 461 on the display unit 43. The display control means 462 also performs display control by analyzing BML, which is an electronic document for data broadcasting. The display control means 462 displays the generated QR code and a guidance sentence that recommends reading the QR code on the screen of the viewing record information issue content.

  The service request accepting unit 463 accepts a request for a viewer service in data broadcasting by calling an API (Application Programming Interface) of DOM (Document Object Mode) by a command described in a BML document transmitted by data broadcasting. is there. Thereby, the service request receiving means 463 determines whether or not a button operation for requesting the viewer service has been performed. Further, the service request accepting unit 463 determines whether or not the digital broadcast receiving apparatus 3 is connected to the communication network N.

  The communication content screen transition unit 464 determines that the digital broadcast receiving device 3a is connected to the communication network N by the service request reception unit 463, and the stamp rally button 815 is displayed in the program linked content 811 shown in FIG. When it is selected, the API is called, and the screen transitions to the stamp rally content 821 that is the communication content, as shown in FIG. 6B.

  The broadcast content screen transition means 465 determines that the digital broadcast receiving device 3b is not connected to the communication network N by the service request accepting means 463, and the stamp rally button 815 is displayed in the program linked content 811 shown in FIG. When selected, the API is called, and the screen transitions to viewing record information issuance content 611 that is broadcast content, as shown in FIG. 6 (d). The viewing record information issuance content 611 is content that is provided by data broadcasting and is not linked to the program being broadcast.

  The two-dimensional code generation unit 466 generates a two-dimensional code in the digital broadcast receiving device 3b that is not connected to the communication network N. When the two-dimensional code generation unit 466 receives an electronic document including a QR code generation program as a receiver program from the digital broadcast transmission device 5, the information (QR code generation program) incorporated in the electronic document is received. Works on the basis of. The two-dimensional code generation means 466 displays the URL character string and the character of the viewing secret information when the viewer performs a button operation for receiving a service when the program-linked content is displayed on the digital broadcast receiving device 3b. A QR code including a column is generated and displayed on the display means 43. The viewing secret information includes time information for viewing the data broadcast, a program ID, and a receiver ID. The two-dimensional code generation unit 466 generates a QR code from text information obtained by concatenating the character string of the viewing secret information after the URL character string of the Web server 6. Thus, the generated QR code varies depending on the generation time, the receiver, and the program.

  The number of characters in the character string used for generating the QR code is selected and set in advance so as to satisfy the specification of the two-dimensional code. For example, in the QR code specification, the number of characters that can be described in the QR code is determined according to the model number (version), error correction level, character type mode, and the like. As a specific example, for example, when the alphanumeric mode, “model number (version)” is “3”, and “error correction level” is “Q”, the total value is defined as “47 characters”. . In the present embodiment, the number of characters in the character string used for generating the QR code is not limited to 47 characters.

  Here, an outline of QR code generation processing by the two-dimensional code generation means 466 will be described with reference to FIG. FIG. 4 is a flowchart showing an outline of a two-dimensional code generation process performed by the digital broadcast receiving apparatus 3 shown in FIG. First, the URL character string and the viewing secret information character string are successively input to the two-dimensional code generating means 466 as text indicating the content that is actually read by the QR code (step S401). For example, text such as “http: // ...” is input.

  Next, the two-dimensional code generation unit 466 encodes the input text (step S402). As a result, for example, text such as “http: // ...” is converted into a bit string (data code word string) in binary representation such as “100110...”. Next, the two-dimensional code generation unit 466 performs numerical calculation. First, an error correction code is calculated and added. The QR code includes Reed-Solomon (RS) error correction that generates a series of error correction code words to be added to the data code word string. Therefore, the two-dimensional code generation means 466 obtains an RS error correction code (error correction code word) by calculation and adds it to the data code word string (step S403).

  Further, the two-dimensional code generation unit 466 performs mask processing (step S404). In the mask process, in order to make it easy to read the QR code by arranging the light module and the dark module in a balanced manner, a module pattern (bit string pattern) given in the encoding area and a plurality of mask patterns (mask process matrix pattern) are used. ) And XOR (exclusive OR) in order, selecting the optimum mask pattern based on the evaluation of the conversion result, and outputting the XOR operation result when the optimum mask pattern is used. . The QR code includes eight types of mask patterns {0,..., 7}. Then, the two-dimensional code generation unit 466 outputs the generated QR code (step S405). For example, a QR code (QR code symbol) configured as a symbol can be displayed on the screen of the display means 43.

  The reissue request accepting unit 467 accepts a reissue request for a two-dimensional code in data broadcasting by calling an API by a command described in a BML document transmitted by data broadcasting. The reissue request accepting unit 467 accepts a reissue request for a two-dimensional code when the viewing record information issuance content 611 is displayed on the digital broadcast receiving apparatus 3b not connected to the communication network N. The reissue request accepting unit 467 determines whether or not an operation for selecting and determining the button 615 for requesting reissue of the QR code 613 shown in FIG. 6D is performed. The operation information of the button 615 is output to the elapsed time determination unit 468 and the reissue information generation unit 469.

  Here, the reissuance of the QR code is a service introduced to improve the usability of the user in a mechanism for preventing multiple registrations based on the same QR code on the Web server 6 side. Note that reissuing represents issuing a QR code related to the first QR code, and does not mean issuing a completely matching QR code.

  The elapsed time discriminating means 468 discriminates whether or not the elapsed time from the time when the screen display of the data broadcast transitions from the program-linked content 811 to the viewing record information issuing content 611 to the time when the reissue request is received is within a predetermined time To do. The elapsed time determining means 468 determines the elapsed time in the digital broadcast receiving device 3b not connected to the communication network N. Here, the predetermined time limits the time for which the QR code can be reissued, and a desired value can be set as appropriate. The predetermined time can be about the program scale, for example, 30 minutes.

  Specifically, assuming that the predetermined time for reissuance is 30 minutes, for example, assuming a 15-minute drama program starting at 8:00 am, data is transmitted to the digital broadcast receiver 3b not connected to the communication network N. If the broadcast screen display transitions from the program-linked content 811 to the viewing record information issuance content 611 at 8:00 am, the reissue acceptance deadline is 8:30 am. This drama program ends at 8:15 am, but since the viewing record information issuance content is an independent content, it can be reissued even at 8:30 am, for example. Thus, for example, in this drama, if the time of transition to the viewing record information issue content is 8:14 am, the QR code can be reissued until 8:44 am on the view record information issue content screen. It becomes.

  The reissue information generation unit 469 generates reissue information necessary for reissuance when a reissue of a QR code is requested in the digital broadcast receiving apparatus 3b not connected to the communication network N. The reissue information generation unit 469 generates reissue information including a predetermined character string when the elapsed time determination unit 468 determines that the elapsed time is within the predetermined time. The reissue information generated here is output to the two-dimensional code generation means 466. The character string as the reissue information is not particularly limited and can be set as appropriate. In view of the convenience of the user who requests reissue, a character string that can be expressed in a plurality of ways is preferable, and may be a random value generated by a random number generator, for example.

  In the present embodiment, when the reissue information generation unit 469 generates reissue information, the two-dimensional code generation unit 466 generates a QR code using a character string including the reissue information in the viewing secret information. did. Of course, the program ID and receiver ID included in the viewing secret information are unchanged even when reissued, and the first issue time is used for time information as well. At the time of reissuance, the difference is that, for example, character strings of random values are connected. As a result, the reissued QR code is different from the QR code at the first issue.

  The reception control means 46 of the digital broadcast receiving apparatus 3 can be realized by operating a computer built in the digital broadcast receiving apparatus 3 by a receiver program that functions as each of the means described above. This receiver program is provided from the digital broadcast transmission device 5 via data broadcasting.

[Web server]
The Web server 6 is a server such as CGI (Common Gateway Interface) or PHP (Hypertext Preprocessor) prepared by a service provider. In this embodiment, a broadcasting station (broadcasting company) also serves as a service company. The Web server 6 registers a viewing record that a viewer who has registered in advance with the service provider's member site while the program content is being broadcast by the digital broadcast receiving device 3, and records the viewing record from the portable terminal 4. A viewer service that can be referred to is provided.

  The Web server 6 includes, for example, an arithmetic device such as a CPU (Central Processing Unit), a storage device (storage means) such as a memory and a hard disk, and an interface device that transmits and receives various types of information to and from the outside. As shown in FIG. 3, the hardware resource is realized by controlling the hardware resources. As shown in FIG. 3, the communication content distribution unit 11, the communication content storage unit 12, the user registration unit 13, the viewing history registration unit 14, and the viewer Information storage means 15 and pre-registration processing means 16 are provided.

The communication content distribution unit 11 distributes communication content including a page screen for providing a viewer service to a communication device of a viewer connected to the communication network N. The communication content is content that can be displayed by a browser or the like. Note that the communication devices connected to the communication network N represent not only the digital broadcast receiving device 3a and the portable terminal 4, but also a desktop or notebook type general personal computer.
The communication content storage unit 12 stores communication content, and includes a storage device such as a memory or a hard disk.

  The user registration means 13 receives member registration (user registration) from the user to the member site of the service provider (also serving as a broadcasting station). The user registration means 13 receives personal information for user registration from a viewer (user) via a communication device connected to the communication network N, registers it in the viewer information storage means 15, and indicates that the registration is completed. The registration completion information is returned to the communication device of the corresponding user. Here, the personal information for user registration represents, for example, information for identifying the person such as a name and address, a user ID (viewer identification information) at the member site, a login password for the member site, and the like.

  The viewing history registration unit 14 associates the viewing record of the viewer with the user ID (viewer identification information) when receiving the request information of the viewer service from the communication device via the communication network N, and stores the database for each user. To register.

The viewer information storage means 15 stores personal information for user registration and personal information of viewers related to the viewer service, and includes a storage device such as a memory or a hard disk.
The viewer information storage means 15 stores the personal information of viewers registered in advance in the member site in a database for each user ID (viewer identification information). Here, the viewer's personal information related to the viewer service is information related to the viewer's viewing record received from the viewer, such as a stamp book and stamp stamp information in the stamp rally service.

  When the pre-registration processing unit 16 receives a connection request from the mobile terminal 4, the registration pre-processing unit 16 receives the request information of the viewer service when logging in to the member site, and registers the viewer's viewing record. The processing is performed. As shown in FIG. 3, the pre-registration processing means 16 includes viewing secret information extraction means 17, discrimination means 18, and registration control means 19.

  The viewing secret information extraction means 17 extracts a character string of the viewing secret information from the request information of the viewer service. In the present embodiment, as an example, the communication content distribution unit 11 determines whether or not the browser of the mobile terminal 4 is logged in to the member site. If the browser of the mobile terminal 4 is not logged in to the member site, the communication content distribution unit 11 displays a login screen. If the browser of the mobile terminal 4 is logged in to the member site, the viewing secret information extraction unit 17 calculates time information, a program ID, and the like from the query added to the request information of the viewer service.

  Here, the viewer service request information is text information acquired by the mobile terminal 4 reading the QR code 613 displayed on the viewing record information issue content 611 (see FIG. 6D). This text information includes a character string in which a URL character string of the Web server 6 and a character string (character string of viewing secret information) called a query string linked to the URL character string are concatenated. It is out. The extracted viewing secret information is output to the determination means 18. Since the viewing secret information is encrypted, the viewing secret information extraction unit 17 performs a corresponding decryption process.

  The discriminating means 18 discriminates whether or not the same information as the viewing secret information extracted by the viewing secret information extracting means 17 is registered in the database of the viewer information storage means 15. The determination result is output to the registration control means 19.

  If the Web server 6 side has already registered the viewing confidential information included in the QR code at the time of the first issuance, it is viewed from the mobile terminal 4 that has read the reissued QR code for the QR code. When the Web server 6 receives the request information for the user service, the determination unit 18 determines that the same information as the viewing secret information extracted by the viewing secret information extraction unit 17 is not registered.

  When the viewing secret information extracted by the viewing secret information extraction unit 17 is not registered, the registration control unit 19 transmits the viewer service request information transmitted from the portable terminal 4 by the viewing history registration unit 14. The record is registered in the database. That is, when the Web server 6 receives the viewer service request information from the mobile terminal 4 and the viewing secret information extracted by the viewing secret information extraction unit 17 is not registered, the viewing control is performed under the control of the registration control unit 19. The history registration unit 14 registers the extracted viewing secret information in the database in association with the user ID.

  On the other hand, when the same information as the viewing secret information extracted by the viewing secret information extraction unit 17 is already registered in the database, the registration control unit 19 distributes the error message to the mobile terminal 4 by the communication content distribution unit 11. Let

In short, the communication content distribution unit 11 distributes the communication content including the page screen for providing the viewer service to the mobile terminal 4 when the viewing secret information is registered by the viewing history registration unit 14, and extracts the viewing confidential information. If the same information is already registered in the database, an error message is distributed to the mobile terminal 4.

  The communication content storage unit 12 stores page screen information corresponding to the determination result of the determination unit 18 as communication content. As an error message in the case of the stamp rally service, for example, “The stamp could not be pressed. The possible causes are as follows: 1. The stamp has already been pressed 2. The data broadcasting screen is displayed. More than a certain amount of time has passed since then, 3. A message has been prepared, such as “Please see the stamp rally page” for details.

  The Web server 6 can be realized by operating a general computer with a viewer service providing program for causing each computer to function as the above-described means. This viewer service providing program can be provided via a communication line, or can be distributed by writing on a recording medium such as a CD-ROM.

[Outline of processing in broadcasting / communication cooperation system]
An overview of processing in the broadcasting / communication cooperation system 1 of FIG. 1 will be described with reference to FIG. Here, it is assumed that the user has viewed the program content with the digital broadcast receiving device 3b not connected to the communication network N. When the user performs a button operation for receiving the viewer service with the remote controller or the like, the digital broadcast receiving device 3b requests the viewer service according to the command of the receiver program sent in the data broadcast BML document. An operation is accepted (step S501). Then, the digital broadcast receiving apparatus 3b acquires the server address (URL) of the Web server 6, the time information for viewing the data broadcast, the program ID, and the receiver ID (step S502). Then, the digital broadcast receiving device 3b generates a QR code based on the acquired information and the two-dimensional code generation program acquired as a receiver program and displays it on the screen (step S503).

  The mobile terminal 4 reads the QR code displayed on the digital broadcast receiving device 3b according to the user's operation (step S504), and accesses the web server 6 via the communication network N (step S505). The Web server 6 extracts viewing secret information from the character string acquired from the mobile terminal 4 (step S506), and determines whether or not the extracted viewing secret information is new information (step S507). If the extracted viewing secret information is new information, the Web server 6 provides the requested viewer service after registering the information in the database of the corresponding member, and the extracted viewing secret information is registered. If it is the same as the completed information, an error message is displayed on the transmission source mobile terminal 4 (step S508). Thereby, the portable terminal 4 displays the communication content of the viewer service based on the determination by the Web server 6 (step S509).

[Stamp Rally Service]
Below, the viewer service is a stamp rally service, and the outline of the processing of each device in the broadcast communication cooperation system 1 will be described with reference to FIGS. 1 and 6. As shown in FIGS. 6 (a) and 6 (c), a program linked content 811 is broadcast as a data broadcast in a drama developing a stamp rally. In the present embodiment, not only the digital broadcast receiving device 3a connected to the communication network N but also the digital broadcast receiving device 3b not connected to the communication network N, as shown in FIG. For example, a stamp rally button 815 is displayed on the content 811 as a red button for proceeding to a page of communication content in data broadcasting.

  When the viewer using the digital broadcast receiving device 3b presses the stamp rally button 815, a QR code is displayed on the screen as shown in FIG. 1 (step S101). Specifically, the program-linked content 811 is a viewing record information issuance content as shown in FIG. 6D when the stamp rally button 815 is selected and the digital broadcast receiving device 3b is not connected to the communication network N. The screen transitions to 611. Note that the program linked content 811 transitions to the stamp rally content 821 as shown in FIG. 6B when the stamp rally button 815 is selected and the digital broadcast receiving device 3a is connected to the communication network N. To do.

  As shown in FIG. 6D, when the viewing record information issue content 611 is displayed on the screen, a broadcast drama (program content) is displayed on the screen in the broadcast program content area 612. In the viewing record information issuance content 611, in addition to displaying various buttons that can be operated by the remote controller by the user, a QR code 613 and a guidance sentence 614 recommending reading thereof are displayed.

  When a viewer using the digital broadcast receiving device 3b reads the QR code 613 with the mobile terminal 4 (step S102: see FIG. 1) and logs in to the Web server 6 that provides the member site according to the read address information, As shown in FIG. 6E, the portable terminal 4 displays stamp rally content 616 that is communication content. Here, the stamp rally content 616 is stamp rally content for the portable terminal 4.

  When the viewer operates the stamp of the stamp rally content on the portable terminal 4, the portable terminal 4 transmits stamp stamp information to the Web server 6 (step S103: FIG. 1). Then, the Web server 6 records the stamp stamp information in the stamp database associated with the member information (Step S104), and returns the stamp stamp result to the portable terminal 4 (Step S105). Then, the mobile terminal 4 displays the stamp stamp result on the stamp rally content 616 page (step S106). Thereby, the viewer can confirm that the stamp is accumulated on the page screen of the stamp rally content 616.

According to the present embodiment, in the service providing system 2, in the case of the digital broadcast receiving device 3b that is not connected to the communication network N, the screen transitions from the program-linked content 811 to the viewing / recording information issue content 611 that displays a QR code, Since the information obtained by reading the QR code can be transmitted to the Web server 6, the convenience of the viewer service such as the stamp rally service can be improved.
In addition, the Web server 6 has received the same viewing secret information as the information already registered in the viewer information storage means 15 from the portable terminal 4 that is considered to have read the QR code displayed in the viewing record information issue content 611. In this case, since the registration is not accepted, an illegal act such as URL diffusion can be prevented. Therefore, it is possible to invalidate the illegal act of the person who obtained the URL information described in the QR code by fraud.

  Furthermore, since the Web server 6 is configured to prevent duplicate registration of the same QR code, the Web server 6 does not recognize that the re-issued QR code is the same QR code. User convenience can be improved. Specifically, the reissuing configuration is such that, for example, a single digital broadcast receiving apparatus 3 is surrounded by a family member or a friend so that a plurality of viewers can simultaneously view each of the viewers for the stamp rally. It is assumed that the QR code is used for reading. In this case, since the viewing secret information matches the program ID and the receiver ID, there is a high possibility that if the subsequent registration is attempted, it will be determined invalid from the second person. Here, focusing on the time information of data broadcasting viewing among the viewing secret information, for example, if the time information is acquired in increments of 1 minute in advance, the second viewer theoretically waits for only 1 minute. It is also possible to register stamp information. However, it cannot be said that the user service is sufficient. Even in such a case, according to the present invention, since the QR code can be reissued for the second and subsequent users, the convenience for the user can be improved.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment. For example, in the present embodiment, the two-dimensional code is described as a QR code, but the present invention is not limited to this.

  Moreover, although the stamp rally service has been described as an example of the viewer service, the present invention is not limited to this. Other viewer services include, for example, a quiz answer recording service that records quiz answers when participating in a viewer participation type quiz program, a questionnaire recording service that records questionnaire responses in a viewer participation type program, or It may be a diary service or the like that records the viewing of the program during the broadcast of the program content as a memo, notebook or diary. For example, in the case of the quiz answer recording service, it is possible to keep a record of what was the first answer of the first question in the program broadcast on X month Y.

  Further, the program content is not limited to a drama already recorded or an animation program produced, but may be a program content of a live broadcast. In the case of live broadcasting, the program staff may insert information such as passwords during live broadcasting for program-linked content of data broadcasting at a broadcasting station. Then, after a user who views live broadcast program content on the digital broadcast receiving apparatus 3 logs in to the member site using a communication device connected to the communication network N and inputs information such as this password, for example, bonus benefits You may be allowed to receive.

  In the Web server 6, the viewer information storage means 15 is divided into a dedicated storage device for personal information for user registration and a dedicated storage device for personal information of viewers related to the viewer service. It may be configured. Further, the Web server 6 may be divided into a user registration dedicated server and a viewer service dedicated server such as a viewing history. In this case, the user registration dedicated server may include a dedicated storage device for user registration personal information and the user registration means 13.
