  However, in the above-described conventional configuration, since the cooperation program for linking a plurality of devices is executed only by one electronic device, it is determined which of the plurality of interconnected electronic devices the cooperation program is executed. The configuration to do is not realized.

  Moreover, in the said conventional structure, it becomes the structure which performs a cooperation program in response to the some electronic device having been mutually connected, and the determination whether to perform a cooperation program is not performed.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an electronic device that can appropriately determine whether to execute the cooperation program in the own device or the counterpart device, and the electronic device. And a control method for the electronic device.

  In order to solve the above-described problem, an electronic device according to the present invention is an electronic device that can be communicably connected to a counterpart device that is another electronic device, and includes status information indicating the status of the counterpart device. And a link program for functionally linking the own device and the partner device based on the status of the device and the status of the partner device indicated by the status information received by the receiver. It is characterized by comprising determining means for determining whether or not to execute in its own device, and program execution means for executing the linkage program in accordance with the determination by the determining means.

  In order to solve the above-described problem, a control method according to the present invention is a method for controlling an electronic device that can be communicably connected to a counterpart device that is another electronic device, and includes status information indicating the status of the counterpart device. Based on the receiving step received from the counterpart device, the status of the counterpart device, and the status of the counterpart device indicated by the status information received in the reception step, for functionally linking the counterpart device and the counterpart device It includes a determination step for determining whether or not to execute the cooperation program in its own device, and a program execution step for executing the cooperation program according to the determination in the determination step.

  According to said structure, a receiving part receives the status information which shows the state of the said other party apparatus from the other party apparatus connected so that communication was possible. And a determination means determines whether a cooperation program is performed in an own apparatus based on the state of an own apparatus, and the state of an other party apparatus. The program execution means executes the cooperation program when the determination means determines that the cooperation program is to be executed in its own device.

  The link program is a program that links the own device and the counterpart device in a functional manner. For example, the link program is a recording reservation program that displays a screen for recording reservation and allows the user to input information regarding the recording reservation. In this case, the electronic devices are a mobile terminal and a television.

  When deciding whether to run the linkage program on the own device or on the other device, the status of each device (for example, whether the device is in the operating state or standby (standby) state) is used as the criterion for cooperation. There is a high possibility that a preferred electronic device for executing the program can be determined.

  Therefore, with the above configuration, the cooperation program can be executed in an electronic device that is preferable for executing the cooperation program.

  Moreover, it is preferable that the said determination means performs the determination which does not run the said cooperation program in an own apparatus, when an own apparatus is not an operation state.

In other words, at least that the own device is in an operating state is set as a necessary condition for executing the cooperation program in the own device. When a plurality of conditions for executing the cooperation program in the own device are set, the cooperation program is executed in the own device when all of the plurality of conditions are satisfied.

  When the own device is in an operating state, there is a high possibility that the user has selected the own device as an operation target. Therefore, by automatically executing the cooperation program in the own device when the own device is in the operating state, the operation of the user intentionally selecting the electronic device on which the cooperation program is executed can be omitted.

  Moreover, it is preferable that the said receiving part is a radio | wireless communication part connected so that communication with the said other party apparatus is possible, when the positional relationship of an own apparatus and the said other party apparatus satisfy | fills a predetermined condition.

  According to said structure, when the positional relationship of an own apparatus and an other party apparatus satisfy | fills a predetermined condition, both apparatuses are automatically connected by radio | wireless communication. Therefore, even when the user does not intend to interconnect the two devices, the two devices are connected to each other if the distance between the two devices is equal to or less than a predetermined distance. Even in this case, when the device is not in an operating state, the linkage program is not executed.

  Therefore, it is possible to reduce the possibility that the cooperation program is executed when the user does not intend.

  Moreover, it is preferable that the said determination means performs the determination which performs the said cooperation program in the electronic device designated beforehand, when an own apparatus and the said other party apparatus are an operation state.

  According to said structure, when all the electronic devices connected so that communication is possible, a cooperation program is performed in the electronic device designated beforehand. Therefore, since all the electronic devices are in the operating state, even when the device that executes the cooperative program cannot be determined based only on the operating state, the device that executes the cooperative program can be determined.

It is preferable to determine whether or not to execute the cooperation program.

  According to said structure, a display part displays the screen regarding operation | movement or operation of an own apparatus. The screen relating to the operation of the own device is, for example, a screen indicating that the cooperation program has been started and a screen indicating functions realized by the started cooperation program. Further, the screen related to the operation of the own device is, for example, a screen for prompting the user to input information necessary for executing the cooperation program, and a screen for the user to input the information.

  The determination unit determines whether or not to execute the cooperation program in the own device based on the state of the display unit included in the own device and the state of the display unit included in the counterpart device. The state information is information indicating whether or not the display unit is in an operating state. For example, the state information is information indicating whether the display unit is in an operating state, a stop state, or a pause (standby) state.

  Therefore, it is possible to determine whether or not to execute the cooperation program in the own device based on whether or not the display units of the own device and the counterpart device are in the operating state. Therefore, the cooperation program can be executed by a device preferable for executing the cooperation program.

  According to said structure, a determination means performs the determination which performs a cooperation program in an own apparatus, when the execution part which commands execution of a cooperation program from an other party apparatus is received in a receiving part. The program execution means executes the linkage program according to the determination by the determination means.

  Therefore, even when the counterpart device is a device that cannot execute the linkage program, the linkage program can be executed in the own device in response to a request from the counterpart device. Therefore, it can be executed in a device preferable for executing the cooperation program.

  Further, the receiving unit receives status information indicating the status of the counterpart device from the counterpart device, and the determination unit is inactive while the cooperation program is being executed in the own device. When the reception unit receives state information indicating that the state has changed to the operation state, it is preferable to determine to stop the execution of the cooperation program.

  According to the above configuration, when the receiving unit receives state information indicating that the counterpart device has changed to the operating state while the cooperation program is being executed in the own device, the determination unit executes the cooperation program. Make a decision to stop.

  When the state of the counterpart device changes from the non-operating state to the operating state, there is a high possibility that the user has performed another operation on the counterpart device. Therefore, with the above-described configuration, it is possible to give priority to an operation newly performed by the user by stopping execution of the cooperation program.

As shown in the figure, the state information includes a transmission header, device attribute data, display attribute data, and a priority flag.

  In the transmission header, an ID (identifier) of a transmission source device, an ID of a transmission destination device, and a packet type are recorded.

  The device attribute data is information indicating whether the state information transmission source device is a main device or a sub device. “1” is displayed when the transmission source device is the main device, and “0” is displayed when the transmission source device is the sub device.

  The display attribute data is information indicating whether the display 11 included in the transmission source device is in an operating state (ON), a paused state or a stopped state (OFF), and is state information in a narrow sense. “1” is displayed when the display 11 is on, and “0” is displayed when the display 11 is off. Note that the sleep state (or standby state) is a state in which the display 11 is not completely turned off and its luminance is lower than that in the normal state. The stop state is a state in which the display 11 is completely turned off.

  The priority flag is information indicating whether or not the own device is prioritized over the partner device with respect to the execution of the recording reservation program. This priority flag is information for deciding on which device the recording reservation program is to be executed when the display 11 is on for both the own device and the partner device. When the recording reservation program is preferentially executed in the own device, “1” is indicated, and “0” is indicated otherwise.

  FIG. 4 is a diagram illustrating an example in which the controller 4 determines a device that executes the recording reservation program from the combination of priority flags. As shown in the figure, when the priority flag of any one device is “1”, the recording reservation program is executed in the device having the priority flag “1”. When both priority flags are “1”, the recording reservation program is executed in the device with the lower ID. When both priority flags are “0”, the automatic activation of the recording reservation program is invalidated. Such a determination method is merely an example, and other determination methods may be used.

  The device ID, device attribute data, and priority flag are set in advance by the user or when the product is shipped, and are stored in the storage unit 13.

(Processing flow in the cooperation system 50)
Next, an example of a processing flow in the cooperation system 50 will be described. FIG. 5 is a flowchart illustrating an example of a processing flow in the cooperation system 50. Here, the mobile terminal 1 will be described as an operation subject. A similar process is performed in the liquid crystal television 20, but the description of the process in the liquid crystal television 20 is omitted.

  First, when the mobile terminal 1 and the liquid crystal television 20 are closer than a predetermined distance, communication between both devices is established by the short-range communication unit 17 (S1).

  When communication is established, the controller 4 requests the display state management unit 2 for display attribute data indicating the on / off state of the display 11 at that time. The display state management unit 2 detects the state of the display 11 in response to the request, and outputs the result to the controller 4 as display attribute data.

  The controller 4 generates state information using the received display attribute data and the device ID, device attribute data, and priority flag acquired from the storage unit 13, and transmits the generated state information via the short-range communication unit 17. Transmit to the LCD TV 20. In this way, the controller 4 also functions as state information generating means.

  Similar processing is also performed on the liquid crystal television 20, and the status information of the liquid crystal television 20 is transmitted from the short-range communication unit 17 of the liquid crystal television 20. This state information is received by the short-range communication unit 17 of the mobile terminal 1 (receiving step). Through these operations, the state information is exchanged (S2).

  When the status information is received from the liquid crystal television 20, the controller 4 of the mobile terminal 1 determines whether or not to execute the recording reservation program on the own device from the combination of the display attribute data of the own device and the display attribute data of the liquid crystal television 20. (Decision step) (S3 to S5).

  If the display 11 of the own device is on (YES in S3) and the display 11 of the liquid crystal television 20 is off (NO in S4), the controller 4 determines to execute the recording reservation program on the own device. Do.

  Controller 4 refers to the priority flag when display 11 of its own device is on (YES at S3) and display 11 of liquid crystal television 20 is on (YES at S4). If priority has been given (YES in S5), the own device decides to execute the recording reservation program. On the other hand, if the own device is not prioritized (NO in S5), the process is terminated. In other words, the controller 4 determines to execute the cooperation program in the electronic device designated in advance when both the display units of the own device and the counterpart device are in the operating state.

  When both the own device and the liquid crystal television 20 are prioritized (priority flag is “1”), the controller 4 refers to the ID of the own device and the liquid crystal television 20, and the ID value of the own device is the liquid crystal. When the value is smaller than the ID value of the television 20, the own device decides to execute the recording reservation program.

  Moreover, the controller 4 complete | finishes a process, when the display 11 of an own apparatus is OFF (it is NO at S3). In this case, the recording reservation program is executed in the liquid crystal television 20 when the display 11 of the liquid crystal television 20 is on, and the recording reservation program is executed in any device when the display 11 of the liquid crystal television 20 is off. Not. Even if the display 11 is off, the communication connection operation is possible as long as the power of the device main body is on.

  When it is determined that the recording reservation program is to be executed by the own device, the controller 4 displays a dialog prompting the user to input an instruction permitting the execution of the recording reservation program (referred to as a cooperation function use confirmation dialog). Is output to the dialog presenting unit 3.

  Upon receiving this command, the dialog presenting unit 3 displays a cooperation function use confirmation dialog on the display 11 (S6). This cooperation function use confirmation dialog includes, for example, a message “Do you want to cooperate with the partner device?”. However, the process of displaying the cooperation function use confirmation dialog is not essential and can be omitted.

  Thereafter, when an instruction to execute the program is obtained from the user via the input unit 12 (S7), the controller 4 outputs an instruction to execute the recording reservation program to the program execution unit 5.

  In response to this command, the program execution unit 5 executes the recording reservation program (program execution step) (S8). At this time, if the recording reservation program is not stored in the storage unit 13, the program execution unit 5 outputs a command for acquiring the recording reservation program to the program acquisition unit 6.

  Upon receiving this command, the program acquisition unit 6 acquires a recording reservation program from the server 30 via the network communication unit 16.

  The program execution unit 5 executes the recording reservation program acquired by the program acquisition unit 6. Specifically, the program execution unit 5 displays a screen for inputting information information necessary for executing the recording reservation program on the display 11, and information related to the recording reservation (recording start time, recording end time, recording target and the like). Information for identifying the program to be acquired) from the user. Thereafter, the acquired information related to the recording reservation is transmitted to the liquid crystal television 20 via the short-range communication unit 17.

  FIG. 6 is a diagram illustrating an operation pattern in the mobile terminal 1 and the liquid crystal television 20. The operations in the portable terminal 1 and the liquid crystal television 20 corresponding to the on / off combination of the display 11 are summarized as shown in FIG. The cooperation function use confirmation dialog is displayed on a device on which the cooperation program is executed.

(Effect of cooperation system 50)
As described above, the cooperation system 50 is a cooperation system including the mobile terminal 1 and the liquid crystal television 20 as a counterpart device of the mobile terminal 1. The portable terminal 1 and the liquid crystal television 20 are a short-range communication unit 17 as a transmission unit that transmits state information indicating the state of the own device to the counterpart device, and a reception unit that receives status information about the counterpart device from the counterpart device. The near field communication unit 17, the controller 4 that determines whether or not to execute the cooperation program in the own device based on the state of the own device and the state of the counterpart device indicated by the status information received by the near field communication unit 17; And a program execution unit 5 that executes the linkage program according to the determination of the controller 4.

  Therefore, based on the state of each device, the cooperation program can be executed in a device preferable for executing the cooperation program.

(Example of change)
In the above description, the state information is information indicating whether the display 11 is in an operating state, but may be information indicating other states of the own device and the counterpart device. That is, the state information may be any information that indicates whether at least one device (for example, main power supply, display device) included in the own device and the counterpart device is in an operating state or a non-operating state. For example, the state information may be information indicating whether the own device and the counterpart device are in an operation state or a hibernation state (standby state).

  Moreover, although the recording reservation program has been described as an example of the cooperation program, other programs may be used as the cooperation program.

  In addition, the device that executes the cooperation program may acquire the cooperation program from the counterpart device instead of from the server 30. In this case, the cooperation program is stored in the storage unit 13 of the counterpart device, and the device that executes the cooperation program may transmit a signal requesting the cooperation program to the counterpart device.

  Also, there may be a plurality of counterpart devices for one electronic device. That is, two or more main devices may be connected to one main device.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIGS. In addition, about the member similar to Embodiment 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted. In the present embodiment, a mobile phone 60 and a liquid crystal television 20 will be described as examples of the electronic apparatus of the present invention. The mobile phone 60 is a sub device that cannot execute the cooperation program in its own device. In this embodiment, an incoming call waiting program will be described as an example of the cooperation program. This incoming call waiting program is a program (application) for displaying a message to that effect on the liquid crystal television 20 and outputting a ringtone from the liquid crystal television 20 when the mobile phone 60 receives an incoming call.

(Configuration of cooperation system 70)
The mobile phone 60 and the liquid crystal television 20 constitute a linkage system 70 for executing an incoming call waiting program that is a linkage program. FIG. 7 is a schematic diagram illustrating a configuration of a cooperation system 70 including the mobile phone 60 and the liquid crystal television 20 according to the present embodiment. As shown in the figure, the linkage system 70 includes a server 30 as a linkage program providing device that provides an incoming call waiting program to the liquid crystal television 20 in addition to the mobile phone 60 and the liquid crystal television 20. The liquid crystal television 20 can obtain the incoming call waiting program from the server 30 when the device does not have the incoming call waiting program.

(Configuration of mobile phone 60)
FIG. 8 is a schematic diagram showing the configuration of the mobile phone 60. As shown in the figure, unlike the mobile terminal 1, the mobile phone 60 includes a main control unit 31 including a controller (decision unit) 32 and a program execution request unit (request generation unit) 33. The main control unit 31 does not include a program execution unit and a program acquisition unit.

  The controller 32 controls each functional block of the main control unit 31. In particular, the controller 32 determines whether to generate a request (program execution request) for executing an incoming call waiting program for the liquid crystal television 20 based on the state of the device itself or the state of the device itself and the liquid crystal television 20. decide. More specifically, the controller 32 requests the program execution based on the display state of the display 11 of the own device or the display state of the display 11 of the own device and the liquid crystal television 20 (in other words, the operation state of the display 11). Determine whether to generate. Details of the processing in the controller 32 will be described later.

  The program execution request unit 33 generates a program execution request according to the determination of the controller 32 and transmits the program execution request to the liquid crystal television 20 via the short-range communication unit 17. Therefore, the short-range communication unit 17 functions as a transmission unit that transmits a program execution request.

(Configuration of LCD TV 20)
The configuration of the liquid crystal television 20 is basically the same as the configuration shown in FIG. 1, but the contents of the processing are partially different.

  The short-range communication unit 17 receives state information indicating the state of the mobile phone 60 (specifically, whether the display 11 is in an operating state) and an execution request for instructing execution of the incoming call waiting program from the mobile phone 60. To do.

  When the controller 4 receives an execution request from the mobile phone 60, the controller 4 determines to execute the incoming call waiting program in its own device. Further, the controller 4 displays a screen relating to the execution of the incoming call waiting program on the display 11 of the own device based on the status information about the display 11 provided in the own device and the status information of the display 11 provided in the mobile phone 60. Decide whether or not. Details of the processing in the controller 4 will be described later.

  The program execution unit 5 executes the incoming call waiting program according to the determination of the controller 4.

(Data structure of program execution request)
FIG. 9 is a schematic diagram showing a data structure of a program execution request. As shown in the figure, the program execution request includes specification information that can specify a transmission header and an incoming call waiting program. This specific information is shown as “application URI (uniform resource identifier)” in FIG. This URI is information indicating the location of the incoming call waiting program to be executed on the Internet, and is information required when the incoming call waiting program is acquired from the server 30. When an incoming call waiting program is stored in the storage unit 13 of the liquid crystal television 20, information that can identify the incoming call waiting program only needs to be included in the program execution request.

(Processing flow in cooperation system 70)
Next, an example of a processing flow in the cooperation system 70 will be described. FIG. 10 is a flowchart illustrating an example of a process flow in the mobile phone 60. FIG. 11 is a flowchart illustrating an example of a processing flow in the liquid crystal television 20. FIG. 12 is a schematic diagram illustrating an example of a processing flow in the cooperation system 70. First, processing in the mobile phone 60 will be described.

  First, when the mobile phone 60 and the liquid crystal television 20 are closer than a predetermined distance, communication between both devices is established by the short-range communication unit 17 (S11).

  When communication is established, the controller 32 requests the display state management unit 2 for display attribute data indicating the on / off state of the display 11 at that time. The display state management unit 2 detects the state of the display 11 in response to the request, and outputs the result to the controller 32 as display attribute data.

  The controller 32 generates state information using the received display attribute data and the device ID, device attribute data, and priority flag acquired from the storage unit 13, and transmits the generated state information via the short-range communication unit 17. Transmit to the LCD TV 20. Thus, the controller 32 also functions as state information generating means.

  Similar processing is also performed on the liquid crystal television 20, and the status information of the liquid crystal television 20 is transmitted from the short-range communication unit 17 of the liquid crystal television 20 (S22). This state information is received by the short-range communication unit 17 of the mobile phone 60. The state information is exchanged by these operations (S12).

  When the status information is received from the liquid crystal television 20, the controller 32 of the mobile phone 60 determines whether to generate a program execution request from the combination of the display attribute data of its own device and the display attribute data of the liquid crystal television 20 (S13-). S14). In other words, the controller 32 determines whether to generate an execution request based on the state of the display 11 included in the device itself and the state of the display 11 included in the liquid crystal television 20.

  If the display 11 of the own device is on (YES in S13) and the display 11 of the liquid crystal television 20 is off (NO in S14), the controller 32 determines to generate a program execution request (FIG. 12 (b)).

  Then, the controller 32 outputs a command for displaying a dialog (cooperation function use confirmation dialog) prompting the user to input an instruction permitting execution of the incoming call waiting program to the dialog presenting unit 3 of the own device. That is, the controller 32 determines whether or not to display a screen related to the execution of the cooperation program on the display 11 of the own device based on the state of the display 11 included in the own device and the state of the display 11 included in the liquid crystal television 20. To do. Specifically, when the display 11 of the own device is on and the display 11 of the liquid crystal television 20 is off, the controller 32 determines to display a screen related to the execution of the cooperation program on the display 11 of the own device. .

  When receiving the above command, the dialog presenting unit 3 displays the cooperation function use confirmation dialog 36 (see FIG. 12) on the display 11 (S15). This cooperation function use confirmation dialog includes, for example, a message “Do you want to cooperate with the liquid crystal television?”.

  Thereafter, when a program execution instruction is acquired from the user via the input unit 12 (S16), the controller 32 outputs an instruction for generating a program execution request to the program execution request unit 33.

  Upon receiving the command, the program execution request unit 33 generates a program execution request for instructing the liquid crystal television 20 to execute the incoming call waiting program, and the generated program execution request is sent to the liquid crystal via the short-range communication unit 17. It transmits to the television 20 (S17).

  On the other hand, when the display 11 of the own device is on (YES in S13), the display 11 of the liquid crystal television 20 is on (YES in S14), and the display 11 of the own device is off. In the case (NO in S13) (FIG. 12 (c)), the series of processes is terminated. In these cases, no program execution request is generated.

  Next, processing in the liquid crystal television 20 will be described. Since steps S21 to S22 in FIG. 11 have already been described, the steps after transmitting / receiving the state information will be described.

  When the status information is received from the mobile phone 60, the controller 4 of the liquid crystal television 20 determines whether or not to execute the incoming call waiting program from the combination of the display attribute data of the own device and the display attribute data of the mobile phone 60.

  If the display 11 of the own device is on (YES in S23), the controller 4 determines to execute the incoming call waiting program (FIG. 12 (a)). In this case, the controller 4 outputs a command to display the cooperation function use confirmation to the dialog presentation unit 3 of the own device.

  Upon receiving this command, the dialog presenting unit 3 displays the cooperation function use confirmation dialog 35 on the display 11 (S24). This cooperation function use confirmation dialog includes, for example, a message “Do you want to cooperate with a mobile phone?”.

  After that, when a program execution instruction is acquired from the user via the input unit 12 (S25), the controller 4 outputs an instruction to execute the incoming call waiting program to the program execution unit 5.

  In response to this command, the program execution unit 5 executes the incoming call waiting program (S26). At this time, if the incoming call waiting program is not stored in the storage unit 13, the program execution unit 5 outputs an instruction for acquiring the incoming call waiting program to the program acquisition unit 6.

  Upon receiving this command, the program acquisition unit 6 acquires an incoming call waiting program from the server 30 via the network communication unit 16.

  Then, the program execution unit 5 executes the incoming call waiting program acquired by the program acquisition unit 6. Specifically, the program execution unit 5 displays a dialog 37 (see FIG. 12) indicating that there is an incoming call to the mobile phone 60 on the display 11 of the liquid crystal television 20 and from a speaker (not shown) of the liquid crystal television 20. Output ringtone.

  On the other hand, controller 4 transmits a program execution request from mobile phone 60 when display 11 of its own device is off (NO at S23) and display 11 of mobile phone 60 is on (YES at S27). It is waited for (S28).

  When the program execution request is transmitted from mobile phone 60 (YES in S28), controller 4 outputs an instruction to execute the incoming call waiting program to program execution unit 5. In response to this command, the program execution unit 5 executes the incoming call waiting program (S29). At this time, the controller 4 turns on the display 11 of its own device.

  On the other hand, when display 11 of the own device is off (NO in S23) and display 11 of mobile phone 60 is off (NO in S27), controller 4 ends the series of processes.

  FIG. 13 is a diagram showing an operation pattern in the mobile phone 60 and the liquid crystal television 20. The operations in the cellular phone 60 and the liquid crystal television 20 corresponding to the on / off combination of the display 11 are summarized as shown in FIG. The cooperation function use confirmation dialog is displayed on the display 11 of the device in which the display 11 is in an operating state. If the displays 11 of both the devices are in an operating state, a cooperation function use confirmation dialog may be displayed on the display 11 of the liquid crystal television 20 which is the main device. In addition, when the displays 11 of both devices are in an operating state, a cooperation function use confirmation dialog may be displayed on a device designated in advance by the user.

(Another example of processing in the linkage system 70)
Next, another example of processing in the cooperation system 70 will be described. Here, a description will be given of a flow of processing for displaying a cooperation function use confirmation dialog in a device designated in advance by the user when the displays 11 of both devices are on. FIG. 14 is a flowchart showing another example of the process flow in the mobile phone 60. FIG. 15 is a flowchart showing another example of the processing flow in the liquid crystal television 20.

Only parts different from the processing flow in the mobile phone 60 shown in FIG. 10 will be described with reference to FIG. When the display 11 of the own device is on (YES in S33) and the display 11 of the liquid crystal television 20 is on (YES in S14), a cooperation function use confirmation dialog is displayed on the sub device (cell phone 60). When the setting to be performed is made by the user (YES in S38), the controller 32 outputs a command to display the cooperation function use confirmation dialog in the own device to the dialog presenting unit 3 (S35).
The subsequent processing flow is the same as steps S15 to S17.

  On the other hand, when the setting for displaying the cooperation function use confirmation dialog on the main device (liquid crystal television 20) is made by the user (NO in S38), the controller 32 ends the series of processes. In this case, a cooperation function use confirmation dialog is displayed on the liquid crystal television 20 as described later.

  Only parts different from the processing flow in the liquid crystal television 20 shown in FIG. 11 will be described with reference to FIG. When display 11 of the own device is on (YES in S43) and display 11 of liquid crystal television 20 is on (YES in S44), a cooperation function use confirmation dialog is displayed on main device (liquid crystal television 20). When the setting to be performed is made by the user (YES in S45), the controller 32 outputs a command for displaying the cooperation function use confirmation dialog in the own device to the dialog presenting unit 3 (S46). The subsequent processing flow is the same as steps S24 to S26.

  On the other hand, when the setting for displaying the cooperation function use confirmation dialog on the sub device (mobile phone 60) is made by the user (NO in S45), the controller 32 ends the series of processes.

  As described above, when the displays 11 of both the devices are on, the user's convenience can be improved by displaying the cooperation function use confirmation dialog on the device designated in advance by the user.

(Another example of processing in the linkage system 70)
Next, still another example of processing in the cooperation system 70 will be described. Here, processing in the liquid crystal television 20 when the display state (operation state) of the display 11 of the mobile phone 60 changes from off to on when the incoming call waiting program is executed in the liquid crystal television 20 will be described. FIG. 16 is a flowchart showing still another example of the processing flow in the mobile phone 60 and the liquid crystal television 20.

  First, when the display state of the display 11 of the mobile phone 60 is turned on when the user operates the mobile phone 60 while the incoming call waiting program is being executed on the liquid crystal television 20 (S61), the display state management unit 2 The display attribute data indicating that the display 11 is turned on is output to the controller 32. The display state management unit 2 may monitor the display state of the display 11 continuously or at predetermined time intervals, and output display attribute data to the controller 32 when the display state of the display 11 changes.

  Upon receiving the display attribute data, the controller 32 generates state information using the received display attribute data and the device ID, device attribute data, and priority flag acquired from the storage unit 13, and the generated state information is It transmits to the liquid crystal television 20 via the distance communication part 17 (S62).

  When the liquid crystal television 20 receives this state information at the short-range communication unit 17 (S71), the controller 4 outputs a command for displaying a cooperation cancellation confirmation dialog to the dialog presenting unit 3. This cooperation cancellation confirmation dialog is a screen for inquiring the user whether or not to cancel the execution of the cooperation program.

  When the above command is received, the dialog presenting unit 3 of the liquid crystal television 20 displays a cooperation cancellation confirmation dialog on the display 11 (S72).

  When an instruction to stop execution of the cooperation program is acquired from the user (YES in S73), controller 4 outputs an instruction to stop execution of the cooperation program (incoming call waiting program) to program execution unit 5.

  Upon receiving this command, the program execution unit 5 stops the execution of the incoming call waiting program (S74). At this time, the liquid crystal television 20 displays, for example, a message “cancel cooperation” on the display 11 or outputs the message as voice (see FIG. 12D).

  Thus, when the display state of the display 11 of the mobile phone 60 changes from off to on, the execution of the cooperation program in the liquid crystal television 20 may be stopped. When the display state of the display 11 of the mobile phone 60 changes from off to on, there is a high possibility that the user is performing another operation on the mobile phone 60. Therefore, the convenience of the user can be improved by automatically terminating the cooperation program in such a case.

  Further, such a configuration may be applied to the mobile terminal 1 and the liquid crystal television 20 of the first embodiment. That is, the controller 4 of the mobile terminal 1 determines to stop the execution of the cooperation program when the display unit of the counterpart device changes from the non-operation state to the operation state while the cooperation program is being executed in the own device. May be.

(Effect of cooperation system 70)
As described above, the cooperation system 70 is a cooperation system including the liquid crystal television 20 as a main device and the mobile phone 60 as a sub device.

  The display device 20 executes a short-range communication unit 17 as a transmission unit that transmits state information indicating the state of the own device to the mobile phone 60, and a cooperation program for functionally linking the own device and the mobile phone 60. A short-range communication unit 17 serving as a receiving unit that receives an execution request for commanding from the mobile phone 60; and a program execution unit 5 that executes a cooperation program when the execution request is received from the mobile phone 60. ing.

  The mobile phone 60 is based on the short-range communication unit 17 as a receiving unit that receives state information about the liquid crystal television 20 from the liquid crystal television 20, and the state of the liquid crystal television 20 indicated by the state and state information of the device itself. A controller 32 that determines whether to generate an execution request, a program execution request unit 33 that generates an execution request according to the determination of the controller 32, and a transmission unit that transmits the execution request generated by the program execution request unit 33 to the liquid crystal television 20 As a short-range communication unit 17.

  Therefore, the linkage program can be executed by the main device in an appropriate situation determined from the state of the own device and the state of the main device.
