The application profile 904 is a value indicating the function of the television receiver required by the application, and indicates a combination of the functions that the television receiver has as an option. By referring to this value, the availability of the application is determined.

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

The activation priority 907 specifies which of the data broadcasting by the broadcasting service and the broadcasting managed application by the HTML document are to be activated with priority at the same time. Unconditionally specify data broadcasting as the highest priority on the PMT, specify the startup priority of a specific application type on the PMT, and specify the startup priority of the target application with the startup priority 907. Shall be possible. The cache information 908 is information used for cache control when holding an application resource in preparation for reuse of an application. With this information, it is possible to cache application resources that are supposed to be reused even after the application is terminated. The server access distribution parameter 909 is a parameter set for distributing access for the purpose of reducing the load on the server where access is concentrated at the acquisition destination of the application or the like. The television receiver may operate to stochastically delay the application of the application control code according to the setting of this parameter.

It is possible to specify whether to start.

FIG. 7A is an operation sequence diagram showing an example of the operation sequence of the broadcast cooperation application when the broadcast cooperation application is specified to be preferentially started. The figure shows a series of flow until the broadcast receiving device 100 appropriately confirms the PMT and AIT and activates a predetermined broadcast cooperation application.

When the tuner / demodulation unit 131 of the broadcast receiving device 100 performs channel selection processing for the channel desired by the user and acquires the TS, then the main control unit 101 acquires the PMT data string separated by the first separation unit 132. (S101), the activation priority described in the PMT is confirmed. When it is confirmed that the activation priority of the broadcast cooperation application is high in the processing of S101 (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 of the data string is confirmed (S104). When the application control code 903 is "automatic start" in the process of S104, the application profile 904 of the acquired AIT data string is further confirmed (S105), and the execution of the broadcast cooperation application specified in the AIT is executed. When it is confirmed that it is possible, the transmission request of the broadcast cooperation application is transmitted 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. (S106).

The service provider server 400 that has received the transmission request of the broadcast cooperation application 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 area 4013. The stored predetermined broadcast cooperation application is distributed via the LAN communication unit 421 (S107). A known method may be used for the authentication process, and detailed description thereof will be omitted. Next, the application engine 162 of the broadcast receiving device 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400 received via the LAN communication unit 121 based on the control of the application control unit 161. (S108).

FIG. 7B is an operation sequence diagram showing an example of an operation sequence of a broadcast cooperation application when it is specified to give priority to data broadcasting by a broadcast service. The figure shows a series of flow until the broadcast receiving device 100 appropriately confirms the PMT and AIT and activates a predetermined broadcast cooperation application.

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

After the processing of S205 or at the same time as the processing of S205, the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S206), and confirms the application profile 904 of the acquired AIT data string. (S207). When it is confirmed in the process of S207 that the broadcast cooperation application specified in the AIT can be executed, the entry button to the executeable broadcast cooperation application is displayed on the data broadcasting screen. The entry button may be always displayed, and the color scheme may be changed from the inactive color to the active color only when the broadcast cooperation application can be executed. By changing the shape, the inactive state and the active state of the entry button may be switched.

When the user selects the entry button using the operation terminal (S208), the data broadcasting engine 142 ends the process of executing the BML document and generating the data broadcasting screen information (S209). Subsequently, the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S210), and confirms 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 the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 (S211).

The service provider server 400 that has received the transmission request of the broadcast cooperation application 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 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 device 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400 received via the LAN communication unit 121 based on the control of the application control unit 161. (S213).

FIG. 7C is an operation sequence diagram showing an example of the operation sequence of the broadcast cooperation application when none of the priority activations is specified. The figure shows a series of flow until the broadcast receiving device 100 appropriately confirms the PMT and AIT and activates a predetermined broadcast cooperation application.

When the tuner / demodulation unit 131 of the broadcast receiving device 100 performs channel selection processing for the channel desired by the user and acquires the TS, then the main control unit 101 acquires the PMT data string separated by the first separation unit 132. (S301), the activation priority described in the PMT is confirmed. When it is confirmed that the activation priority of the broadcast cooperation application is high in the processing of S301 (S302), the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S303), and the acquired AIT The application control code 903 of the data string is confirmed (S304). In the process of S304, when the application control code 903 is "startable" instead of "automatically started", the display of the broadcast program is continued without starting either the data broadcasting by the broadcasting service or the broadcasting cooperation application.

When the user makes a data broadcasting activation request using the operation terminal in the state after the processing of S304 is completed (S305), the acquisition of the BML data string and the BML are performed in the same manner as the processing after S205 in FIG. 7B. Documents are played back, data broadcasting screen information is generated, etc. (however, not shown). On the other hand, when the user makes a request to start the broadcast cooperation application launcher using the operation terminal in the state after finishing the processing of S304 (S306), the application control unit 161 separates the AIT data by the first separation unit 132. The 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 cooperation applications on the video display unit 173 as a broadcast cooperation application launcher (S309).

When the user selects a predetermined broadcast cooperation application from the broadcast cooperation application launcher displayed in S309 using the operation terminal (S310), the application control unit 161 selects the AIT data string separated by the first separation unit 132. Acquired (S311), and confirms 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 S311, a 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 of the broadcast cooperation application 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 area 4013. The stored predetermined broadcast cooperation application is distributed via the LAN communication unit 421 (S313). Next, the application engine 162 of the broadcast receiving device 100 activates the predetermined broadcast cooperation application distributed from the service provider server 400 received via the LAN communication unit 121 based on the control of the application control unit 161. (S314).

In the activation sequence of the broadcast cooperation application described with reference to FIGS. 7A to 7C, an example of acquiring AIT from the broadcast wave is described, but a predetermined server device specified by the information description of PMT or the like is described. You may try to get the AIT file from. Further, the acquisition of the broadcast cooperation application may be performed not from the server device (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 HTML data string transmitted by the application control unit 161 by the data carousel method or the like and separated and output by the first separation unit 132. The HTML document may be reproduced from the above, and the reproduced HTML document (broadcasting cooperation application) may be executed by the application engine 162.

If there is no information to specify the activation priority when the data broadcasting by the broadcasting service and the broadcasting cooperation application exist at the same time on the PMT, the activation is performed only by the information such as the AIT application control code 903 and the activation priority 907. You may want to check the priority. Similarly, even if 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 AIT and the activation priority 907. That is, the AIT is checked periodically regardless of the information on the PMT, and if the broadcast cooperation application specified by "automatic start" exists in the application control code 903 of the AIT, the broadcast cooperation application is used. Priority may be given to activation, and if the broadcasting cooperation application specified by "automatic activation" does not exist in the application control code 903 of AIT, the activation of data broadcasting by the broadcasting service may be prioritized.

If there is no response from the service provider server 400 for a predetermined time or more when a broadcast cooperation application distribution request is made in S106, S211, or S312, a message such as "Please wait" is sent to the video display unit 173. It may be displayed. Alternatively, in this case, a message inquiring the user to cancel the execution of the broadcast cooperation application may be displayed.

Further, it goes without saying that the activation sequence of the broadcast cooperation application is not limited to the above-mentioned three patterns, and may be activated by a different sequence.

[Operation sequence when linking mobile information terminals]
In the broadcast receiving device 100 of this embodiment, it is assumed that the function of the broadcasting communication cooperation service can be expanded by the cooperation operation between the broadcasting receiving device 100 and the mobile information terminal 700.

Further, the broadcast cooperation application can be executed on the mobile information terminal 700, and for example, a service linked to the broadcast program displayed by the broadcast receiving device 100 can be displayed on the mobile information terminal 700. In addition, in order to expand the function by the cooperative operation between the broadcast receiving device 100 and the mobile information terminal 700, it is desirable that the cooperative control application is started on the mobile information terminal 700 and operates on the mobile information terminal 700. It is assumed that the broadcast cooperation application to be operated is controlled by the cooperation control application.

FIG. 8A is an operation sequence diagram showing an example of an operation sequence when the cooperation control application is started on the mobile information terminal 700. The figure shows a series of flow (first time) until the mobile information terminal 700 performs the authentication process with the broadcast receiving device 100 and the cooperative operation becomes possible. It is assumed that the cooperation control application is installed in the storage unit 710 of the mobile information terminal 700 in advance as the cooperation control program 7002.

When the user instructs to start the cooperation control application on the mobile information terminal 700 (S401), the cooperation control execution unit 7102 of the mobile information terminal 700 searches for a TV receiver capable of communication (cooperation operation) on the network (S). S402), the search results are displayed on the display unit 741 as a list of television receivers. If a communicable TV receiver cannot be found, a message to that effect is displayed and the process ends. When the user selects an arbitrary TV receiver (broadcast receiving device 100 of this embodiment) from the TV receiver list, the cooperation control execution unit 7102 displays a login screen for connecting to the broadcast receiving device 100 on the display unit 741. do.

In the broadcast receiving device 100 of this embodiment, when it is determined that the broadcast cooperation application cannot be executed, the reason why the broadcast cooperation application cannot be executed, such as the confirmation result of the application profile 904, is explained. It is displayed in the error message 173d1. For example, as a result of checking the application profile 904, if the predetermined optional function is insufficient on the television receiver side, an error message 173d1 to that effect is displayed. The error code and the guide (URL, etc.) of the homepage of the television receiver manufacturer in which the explanation of the error code is described may be displayed. Alternatively, when acquiring the broadcast cooperation application from the network, of course, the connection status of the network is confirmed in advance, but at this time, for example, the acquisition of the broadcast cooperation application is performed due to an inadequate connection of the LAN cable or the like. If this is not possible, an error message 173d1 to that effect is displayed. Further, the error message 173d1 may be displayed even when the network connection is established but the broadcast cooperation application cannot be acquired correctly 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 broadcast cooperation application cannot be executed yet. In addition, the error message 173d1 is displayed even when the reception status of the broadcast wave is not stable and the information such as AIT cannot be received in the middle of the process even though the information such as AIT could be received at the beginning. good. In such a case, if the broadcast cooperation 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 restored.

In addition, as a result of checking the application profile 904, if the predetermined optional function is insufficient on the TV receiver side, the error message 173d1 is displayed to recommend checking or updating the latest firmware for the TV receiver. You may do so. Alternatively, the broadcast receiving device 100 may automatically check or update the latest firmware. Alternatively, if the broadcast cooperation application can be executed by adding paid optional hardware or software to the TV receiver, the information on the paid optional hardware or software may be displayed. good. The error message 173d1 may be displayed on the mobile information terminal 700 instead of the broadcast receiving device 100.

By operating the broadcast cooperation application (terminal side) on the mobile information terminal 700, it is possible to expand the function of the broadcast communication cooperation service by the cooperation operation between the broadcast receiving device 100 and the mobile information terminal 700.

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

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

In the title area 173e2, a program title of each broadcast program, a symbol representing an attribute of each broadcast program, and the like are displayed. The symbols and the like representing the attributes of each broadcast program are, for example, a mark symbolizing "New" meaning a new program, a mark symbolizing "Replay" meaning a rebroadcast program, and the like. And so on. Alternatively, it may be a mark or the like symbolizing "data" which means that it corresponds to data broadcasting by a broadcasting service. Further, in the case of a broadcast program for which a broadcast cooperation application that can be executed by the broadcast receiving device 100 of this embodiment is prepared, a mark or the like symbolizing "Linkage" indicating that fact may be used. The detailed explanation area 173e3 displays related information such as the program contents and performers of each broadcast program, the URL of the homepage introducing each broadcast program, and the like.

The mark or the like symbolizing the "Linkage" displayed in the title area 173e2 is an information display device as a result of confirmation of the application profile 904 even when the broadcast cooperation application is prepared for the broadcast program. If the execution at 100 is not possible, it may not be displayed. In addition, the mark that symbolizes "Linkage", which is displayed in the title area 173e2 and indicates that the program is a broadcast program for which the executable broadcast cooperation application is prepared, can be further linked with a mobile terminal device. The color, shape, font, etc. may be changed depending on whether or not. When the operation in cooperation with the mobile terminal device is possible, the mark symbolizing "Mobile" may be displayed together with the mark symbolizing "Linkage".

Whether or not the mark symbolizing "Linkage" or the mark symbolizing "Mobile" is displayed is described in advance in the EIT information including detailed information of each broadcast program, and each broadcast program is a book. Whether or not the broadcast program is provided with a broadcast cooperation application that can be executed by the broadcast receiving device 100 of the embodiment, and whether or not the executeable broadcast cooperation application can operate in cooperation with a mobile terminal device. It may be controlled by acquiring information such as. Alternatively, the information acquired from the program distribution information of the digital broadcast program prepared in the predetermined server device on the Internet 200 is added to the electronic program table created based on the program information data string acquired from the broadcast wave of the digital broadcast service. You may add it.

As described above, on the EPG display screen 173e, a mark symbolizing "Linkage" indicating that the program is a broadcast program for which an executable broadcast cooperation application is prepared, and cooperation operation with a mobile terminal device are possible. By displaying the mark symbolizing "Mobile" indicating "Mobile", the user can easily grasp the correspondence status of each broadcast program in the broadcast receiving device 100 to the broadcast communication cooperation service. Needless to say, the mark in which a 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 correspondence status of each broadcast program to the broadcast communication cooperation service may be shown. Further, the mark symbolizing "Linkage" and the mark symbolizing "Mobile" are not normally displayed in the title area 173e2, and pop up only when each broadcast program is selected by the program selection cursor 173e4. It may be displayed.

The broadcast receiving device 100 of this 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 by using the cursor key 741ac of the basic screen 741a of the cooperation control application, and an arbitrary broadcast program is used by the enter key 741ad. By selecting, the viewing reservation and / or the recording reservation of the selected broadcast program is performed.

In the above-mentioned processing, when the broadcast program for which the viewing reservation and / or the recording reservation is made is a broadcast program corresponding to the broadcast communication cooperation service, the broadcasting is triggered by the viewing reservation and / or the recording reservation. The acquisition of the broadcast cooperation 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 designating the acquisition destination of the broadcast cooperation application is described in the EIT information including the detailed information of each broadcast program. By doing so, the broadcast receiving device 100 can grasp the information of the acquisition destination of the broadcast cooperation application prepared for each broadcast program when the broadcast program is selected by the program selection cursor 173e4. Become. Therefore, the broadcast receiving device 100 can start the acquisition of the broadcast cooperation application before the broadcast start time of the broadcast program is reached.

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

In this way, if the broadcast receiving device 100 refers to the acquisition destination information of the broadcast cooperation application included in the EPG information and starts the acquisition of the broadcast cooperation application before the broadcast start time of the broadcast program. , It becomes possible to distribute the load of the service provider server 400 that stores the broadcast cooperation application. Further, even when the communication speed of the network between the service provider server 400 and the information display terminal 100 is insufficient, the broadcast cooperation application can be effectively used immediately after the start of broadcasting of the broadcast program. become.

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

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

After the process of S706, the application control unit 161 transmits a transmission request of the broadcast cooperation application to the 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 of the broadcast cooperation application 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 area 4013. The stored predetermined broadcast cooperation application is distributed 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 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 having higher added value.

Hereinafter, the second embodiment of the present invention will be described. The configuration and effects of this example shall be the same as those of Example 1 unless otherwise specified. Therefore, in the following, the differences between the present embodiment and the first embodiment will be mainly described, and the common points will be omitted as much as possible in order to avoid duplication.

Although the embodiment in the case of performing the mobile information terminal cooperation processing (hereinafter referred to as terminal cooperation) is described in the first embodiment, a more detailed embodiment will be described.

When linking mobile information terminals, it may be desired to limit the use of terminal linkage only to the mobile information terminal 700 in the same home as the broadcast receiving device 100 (hereinafter, this limitation is referred to as the same home restriction). For example, in an application for using broadcast cooperation (hereinafter referred to as a broadcast cooperation application), the display screen of the broadcast receiving device 100 and the display screen of the mobile information terminal 700 are closely related, or the broadcast receiving device 100. This is a case where the user of the mobile information terminal 700 is surely to watch the displayed advertisement video.

The point that must be considered as a procedure is the judgment of whether or not the target broadcast cooperation application imposes the same in-home restriction. This judgment is not necessary if it is assumed that all broadcast cooperation applications have the same in-home restriction, but if there is no restriction, the broadcast receiving device 100 provides control information regarding the presence or absence of the same in-home restriction. Needs to get and change the operating procedure. The control information regarding the presence or absence of this restriction may be acquired from a broadcast signal (for example, described as an item of AIT), or may be acquired from a server designated by a broadcasting station.

Including the above procedure, in this embodiment, the procedure for guaranteeing that the mobile information terminal 700 exists in the same house as the broadcast receiving device 100 will be described.

Usually, the devices existing in the same house exist on the local network connected to the same router device 210. Therefore, since the mobile information terminal 700 is connected to the same local network as the broadcast receiving device 100, it can be determined that the mobile information terminal 700 exists in the same house. Whether or not the target device is connected to the local network may be determined by using a known method, and the description thereof will be omitted.

Further, even if the mobile information terminal 700 is not on the local network, it can be determined that it exists 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 cooperation application or the like may be the above-mentioned direct communication or mobile telephone communication.

As described above, a plurality of methods for confirming the existence in the same house can be considered, but which method is to be used is described in, for example, AIT, and is read by the broadcast receiving device 100.

Further, once it can be confirmed that the mobile information terminal 700 exists in the same house, it may be regarded as existing in the same house until the end of the program, or a certain effective time (for example, 10 minutes) is set and within the effective time. Is considered to exist in the same house, but if the valid time has passed, it can be considered that it does not exist in the same house without new confirmation. This effective time is described in, for example, AIT, and is read by the broadcast receiving device 100.

Further, for example, an event signal is set in the broadcast signal at any time during the program, and each time the event signal is received, it is confirmed that the mobile information terminal 700 exists in the same house. You can also.

It is also possible to use the former two methods in combination.

Next, a specific procedure for permitting terminal cooperation only to the mobile information terminal 700 existing in the same house will be described. In this embodiment, restrictions are set when the mobile information terminal 700 acquires the broadcast cooperation application or the information used in the broadcast cooperation application (hereinafter, the information used in the broadcast cooperation application and the broadcast cooperation application, specifically. These are, for example, HTML documents and streaming video, but these are collectively referred to as broadcast cooperation information). There are two types of broadcasting cooperation information acquisition methods: communication acquisition acquired from the broadcasting station server 300 or the operator server 400, and broadcasting acquisition acquired from the broadcast wave. In the case of communication acquisition, there are two types, one is to acquire after the start of broadcast reception and the other is to acquire before the start of broadcast reception. Further, in the case of communication acquisition, there are cases where the broadcast receiving device 100 once acquires and the mobile information terminal 700 acquires from the broadcast receiving device 100, and cases where the mobile information terminal 700 directly acquires from the broadcasting station server 300 or the operator server 400. There is. There are various methods, but when viewed from the mobile information terminal 700, they can be roughly divided into two cases, one is to acquire from the broadcast receiving device 100 and the other is to acquire from the broadcasting station server 300 or the operator server 400.

In this embodiment, the case where the mobile information terminal 700 acquires the broadcast cooperation information from the broadcast receiving device 100 will be described, and the case where the mobile 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 terminal cooperation, each of the mobile information terminal 700 and the broadcast receiving device 100 activates a cooperation control application, which is an application for controlling terminal cooperation (S10001, S10002). In this state, the mobile information terminal 700 makes a terminal cooperation request to the broadcast receiving device 100 (S1003). Next, AIT is acquired from the broadcast signal (S10004). From this AIT information, it is determined whether the target mobile information terminal application has the same in-home restriction (S10006), and if there is a restriction, proceed to the procedure of S10008, and the first stage when the terminal cooperation request is made. Then, the process proceeds to the step of S1009, and it is determined whether or not the portable information terminal 700 for which the terminal cooperation request has been made is in the same house as the broadcast receiver 100 (S1009). As a result of the determination, if it is determined that they are not in the same house, a response of disapproval of cooperation is made to the cooperation control application on the mobile information terminal side, and the process is terminated (S10011).

Here, in the first place, if it is assumed that all the broadcast cooperation applications have the same in-home restriction, the determination of S10006 is not performed and the application is skipped. The determination of S10006 is performed when there may be both an application having the same in-home restriction and an application not having the same in-home restriction.

If it is determined that the mobile information terminal 700 is in the same home, or if the application has no restrictions in the same home, the process proceeds to S10012 to provide a broadcast cooperation application-related service. This service (S10012) processes the broadcast cooperation information distribution request (S10013) from the mobile information terminal 700, and distributes the broadcast cooperation information to the mobile information terminal 700 (S10018). The broadcast cooperation information includes information distributed by the broadcast receiving device 100 from the distribution server which is the operator server 300 (S10014, S10015, S10016), information acquired from the broadcast signal (S10017), and stored in the broadcast receiving device 100. There are things that have been done. The reception of the broadcast cooperation information (S10016, S10017) by the broadcast reception device 100 is not limited to the case of the broadcast cooperation information distribution request (S10013) from the mobile information terminal 700, but the broadcast reception device 100 autonomously acquires the information. It may be acquired based on the occurrence of an event from a broadcast signal. The distribution of the broadcast cooperation information (S10018) to the mobile information terminal 700 may also be voluntary from the broadcast receiving device 100 side.

After receiving (acquiring) and distributing a series of broadcast cooperation information, it is determined whether or not the broadcast receiving device 100 continues to watch the same program (S10019), and if not, the mobile information terminal side. A response of disapproval of cooperation is made to the cooperation control application, and the process is terminated (S10020).

If the viewing is continued, the procedure returns to S1005, and if there is a home restriction, it is confirmed whether the mobile information terminal 700 is in the same home (S10009), but the preset valid time has elapsed since the previous confirmation. It is determined whether the confirmation request (S10007) has been generated from the broadcast signal or the distribution server since the previous confirmation (S10008), and if none of the conditions are met, it is determined whether the user is in the same house. The confirmation (S10009) is not performed, and the next broadcast cooperation application-related service (S10012) is executed via S10010. Here, the confirmation request (S10007) from the broadcast signal is described so as to be acquired from the broadcast cooperation information, but 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 of S10022. The confirmation request of S10007 may be made at any timing in the loop.

Further, the authentication information described in the AIT may be incorporated in the authentication key used for the authentication (S10015) on the distribution server. This confirms that the authentication request is legitimate. Further, if the authentication information described in the AIT is changed as the program progresses and the distribution server does not perform authentication unless the authentication key incorporates the information synchronized with the progress of the program, the same program is used. You can confirm that you continue to watch. In this case, the AIT information is appropriately read and updated (S10021). The authentication information to be incorporated into the broadcast signal may be incorporated as broadcast cooperation information in addition to being described in the AIT. Furthermore, as a method of substantially changing the authentication information, it is also possible to use a method of changing the URL itself of the distribution server according to the progress of the program.

In this way, while executing the broadcast cooperation application-related service (S10012), the portable information terminal 700 receives the broadcast every preset valid time, or every time there is a broadcast signal or a confirmation request from the distribution server. By confirming whether or not the device 100 is in the same house, it is possible to appropriately execute a broadcast-related application having the same house restriction. Furthermore, by using the authentication information embedded in the broadcast signal for authentication on the distribution server, the validity of the distribution request can be ensured, and if the authentication information of the broadcast signal is changed as appropriate, the same program can be used. You can also confirm that you are continuing to watch.

According to the mobile information terminal cooperation technique according to the present embodiment described above, it is possible to realize the same in-home restriction for the mobile information terminal linked with the broadcast receiving device.

In this embodiment, a case where the mobile information terminal 700 acquires broadcast cooperation information from the distribution server will be described.

FIG. 18B shows the procedure of this embodiment.

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

After that, the loop control indicated by the arrow of S10127 is entered.

First, the mobile information terminal 700 issues an authentication key issuance request or a broadcast cooperation information distribution request to the broadcast receiving device 100 (S10109). The authentication key is used in the broadcast cooperation information distribution request to the distribution server in the subsequent stage (S10125). The broadcast cooperation 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 mobile information terminal, it is determined whether the application is a broadcast cooperation application having the same in-home restriction (S10111), and if there is a restriction, the process proceeds to the next procedure S10112, and if not, the procedure of S10112 is Skip to S10114. If all the broadcast cooperation applications have the same in-home restriction, the determination of S10111 is not performed and the process proceeds to S10112. In S10112, it is determined whether or not the mobile information terminal that issued the request is in the same house, and if not, the terminal cooperation is terminated (S10113). If they are in the same house, the requested procedure, acquisition of broadcast cooperation information from the distribution server (S10125), or acquisition of broadcast cooperation information from the broadcast signal (S10126) is performed. Since acquisition from the broadcast signal may be performed in addition to acquisition from the distribution server, the procedure of S10126 is also described.

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

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

The preset valid time may be held in the distribution server, or the broadcast receiving device 100 may acquire the valid time from the broadcast signal (for example, AIT) and incorporate the valid time information into the authentication key. The mobile information terminal 700 is notified in advance of the valid time information, and the issuance of the authentication key is requested before the valid time expires. Alternatively, the valid time is managed by the broadcast receiving device 100, and before the valid time expires, after confirming that the mobile information terminal 700 is in the same house, the broadcast receiving device 100 automatically shifts to the mobile information terminal 700. You may issue an authentication key for this.

The valid time may be the same in one program, or may be changed according to the progress of the program. Further, if the valid time is not set, the authentication may be valid while the program is being watched once the authentication is performed.

Further, the authentication information described in the AIT may be incorporated in the authentication key used for the authentication (S10117) on the distribution server. This confirms that the authentication request is legitimate. Further, if the authentication information described in the AIT is changed as the program progresses and the distribution server does not perform authentication unless the authentication key incorporates the information synchronized with the progress of the program, the same program is used. You can confirm that you continue to watch. In this case, the AIT information is appropriately read and updated (S10124). The authentication information to be incorporated into the broadcast signal may be incorporated as broadcast cooperation information in addition to being described in the AIT. Furthermore, as a method of substantially changing the authentication information, it is also possible to use a method of changing the URL itself of the distribution server according to the progress of the program. The URL change in this case is when the distribution server is the same but the entrance is different, but it may be changed to a new distribution server due to a change in the broadcasting cooperation application or the like. In this case, each time a change is made, the procedures of distribution server information transmission (S10105), time confirmation request (S10106), and time information transmission (S10107) are performed.

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

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

When the broadcast cooperation information is changed as the program progresses, the change notification may be issued from the broadcast signal (S10110), and the broadcast cooperation information may be acquired as a trigger. In that case, if it is acquired from the distribution server, the broadcast receiving device 100 issues an authentication key to the mobile information terminal (S10115) to notify 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 used. In the case of acquisition from a broadcast signal, the broadcast receiving device 100 acquires the information (S10119) and distributes it to the mobile information terminal (S10120). In the case of acquisition from a broadcast signal, it may be confirmed that the mobile information terminal 700 is in the same house for each change notification, and the confirmation is omitted if it is within the valid time as in the second embodiment. It doesn't matter. Here, the change notification (S10110) from the broadcast signal is described so as to be 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 a series of broadcast cooperation information, it is determined whether or not the broadcast receiving device 100 continues to watch the same program (S10121), and if not, the mobile information terminal side. A response of disapproval of cooperation is made to the cooperation control application, and the process is terminated (S10123). If the viewing is continued, the process returns to S10108 and the loop processing S10127 is continued.

In this way, by including the time information in the authentication key used for authentication of the distribution server and managing the valid time, it can be confirmed that the portable information terminal 700 is in the same house as the broadcast receiving device 100 on a regular basis. It is possible to appropriately execute a broadcast cooperation application that has the same in-home restrictions. Furthermore, by using the authentication information embedded in the broadcast signal for authentication on the distribution server, the validity of the distribution request can be ensured, and if the authentication information of the broadcast signal is changed as appropriate, the same program can be used. You can also confirm that you are continuing to watch.

According to the mobile information terminal cooperation technique according to the present embodiment described above, even when the mobile information terminal linked with the broadcast receiving device acquires the broadcast cooperation information from the distribution server, it is possible to realize the same in-home restriction. ..

In Examples 2 and 3, the procedure for realizing the same in-home restriction in terminal cooperation has been described, but depending on the broadcast cooperation application, use from outside the house may be permitted. In this embodiment, such a case will be described. For example, when a program such as TV shopping itself is a public relations / promotion, it is desirable for a broadcaster to be able to use a broadcast cooperation application regardless of whether it 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 cooperation application may be permitted regardless of whether or not the mobile information terminal 700 is in the house. In this case, if there is a broadcast cooperation application that converts the broadcast video itself into streaming data and distributes it from the broadcast receiving device 100 to the mobile 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 cooperation application permits use from outside the home, including the distribution of the broadcast video outside the home, is described in the data in the broadcast signal (for example, AIT).

The specific procedure is shown in FIG. 18C. Since some of the procedures are common to Examples 2 and 3, the description of the parts overlapping with Examples 2 and 3 will be omitted. When the broadcast receiving device 100 receives a terminal cooperation request (S10203) from outside the home, the broadcast receiving device 100 confirms whether the request source is a registered mobile information terminal if the application is permitted to be used outside the home (S10203). In S10205), the cooperation is permitted. Here, if necessary, the mobile information terminal 700 and the broadcast receiving device 100 may perform authentication in order to protect the copyright of the broadcast video and the broadcast cooperation information (S10207). At that time, the authentication may be the authentication in the distribution server (S10207). Information on the necessity of copyright protection and information on the authentication method for copyright protection are acquired from a broadcast signal (for example, it is described in AIT), and control is performed accordingly. When such information is not stored in the broadcast signal, a predetermined method predetermined in the broadcast receiving device 100 is followed. For example, a predetermined copyright protection process may be performed. Further, if such information is not stored in the broadcast signal, it may be determined in advance that the broadcast receiving device 100 does not perform the copyright protection process.

A specific example of certification for copyright protection is shown below. Only one of the following certifications may be performed. Alternatively, a combination of a plurality of authentications exemplified below may be performed. Further, the authentication exemplified below may be performed in combination with other authentication processes not exemplified below.

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

[Use of distribution server]
A method of issuing an encryption key for decrypting encrypted video data, etc. from a distribution server. The mobile information terminal 700 transmits an ID and a password to the distribution server, and acquires an encryption key. In this case, the location information (specifically, the URL) of the distribution server is acquired from the broadcast signal (for example, described in the AIT), and this location information is transmitted from the broadcast receiving device 100 to the mobile information terminal 700. It is more secure. Since the video or the like cannot be decrypted unless the mobile information terminal 700 can obtain the encryption key, the broadcast receiving device 100 may request authentication on the distribution server to authenticate the protection of writing rights, or the mobile information terminal. The authentication may be completed by notifying the broadcast receiving device 100 from the 700 that the encryption key has been acquired. Note that billing by the distribution server may be performed.

[Mutual authentication of encryption key]
The encryption keys of the broadcast receiving device 100 and the mobile information terminal 700 are mutually authenticated and confirmed to be copyright protection.

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

When the terminal cooperation is permitted, it is not confirmed whether or not the mobile information terminal 700 exists in the same house thereafter, but the request from the mobile information terminal 700 (S10211), the autonomous control of the broadcast receiving device 100, and the broadcast signal. In accordance with the request from (S10210), the broadcast cooperation information is distributed to the mobile information terminal 700 (S10217), and the authentication key for the distribution server is issued (S10212). In this case, it is not necessary to control the effective time. The mobile information terminal 700 outside the home acquires broadcast cooperation information from the distribution server using the broadcast receiving device 100 or the issued authentication key (S10215). Further, the authentication key issued by the broadcast receiving device 100 incorporates the authentication information acquired from the broadcast signal (for example, it is described in the AIT), and the distribution server uses the authentication key incorporating the authentication information acquired from the broadcast signal. If there is, if access is permitted, it is possible to further optimize the use outside the home.

In addition, there are cases where it is better not to allow unlimited use of broadcast-linked apps, such as when discounting as a premium for watching programs. In such cases, authentication should be performed once with a mobile information terminal in the same home. After that, it is preferable to allow the use of the distribution server even if it is not in the same house. In this case, the mobile information terminal 700 may not be registered in the broadcast receiving device 100.

A specific procedure in this case is shown in FIG. 18D. Since some of the procedures are the same as those in FIG. 18C, the description of the overlapping parts will be omitted. First, in a state where the mobile information terminal 700 is in the same house as the broadcast receiving device 100, the mobile information terminal 700 makes a terminal cooperation request to the broadcast receiving device 100, and the broadcast receiving device 100 has the mobile information terminal 700 in the same house. After confirming that it is in (S10305), the cooperation is permitted. Here, if necessary, the mobile information terminal 700 and the broadcast receiving device 100 may perform authentication in order to protect the copyright of the broadcast video and the broadcast cooperation information (S10307). At that time, the authentication may be authentication on an external distribution server. Information on the necessity of copyright protection and information on the authentication method for copyright protection are acquired from a broadcast signal (for example, it is described in AIT), and control is performed accordingly. When such information is not stored in the broadcast signal, a predetermined method predetermined in the broadcast receiving device 100 is followed. For example, a predetermined copyright protection process may be performed. Further, if such information is not stored in the broadcast signal, it may be determined in advance that the broadcast receiving device 100 does not perform the copyright protection process.

A specific example of certification for copyright protection is shown below. Only one of the following certifications may be performed. Alternatively, a combination of a plurality of authentications exemplified below may be performed. Further, the authentication exemplified below may be performed in combination with other authentication processes not exemplified below.

[Use encryption key]
While the mobile information terminal 700 is in the same house, the broadcast receiving device 100 transmits an encryption key for decrypting the encrypted video data or the like to the mobile information terminal. This encryption key may be obtained from a broadcast signal (for example, described in AIT). Authentication is performed by handing over this encryption key in the same house. Furthermore, if the encryption key cannot be obtained from the broadcast signal until a certain point in the program and the transfer of the encryption key to the mobile 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 it can also be used to give a premium to viewing.

[Use of distribution server]
A method of issuing an encryption key for decrypting encrypted video data, etc. from a distribution server. The mobile information terminal 700 transmits an ID and a password to the distribution server, and acquires an encryption key. In this case, the location information (specifically, the URL) of the distribution server is acquired from the broadcast signal (for example, described in the AIT), and this location information is transmitted from the broadcast receiving device 100 to the mobile information terminal 700. It is more secure. Since the video or the like cannot be decrypted unless the mobile information terminal 700 can obtain the encryption key, the broadcast receiving device 100 may request authentication on the distribution server to authenticate the protection of writing rights, or the mobile information terminal. The authentication may be completed by notifying the broadcast receiving device 100 from the 700 that the encryption key has been acquired. Access to the distribution server may be performed inside or outside the home, but the location information of the distribution server cannot be obtained from the broadcast signal until at a certain point in the program, and the location information is sent to the mobile information terminal 700. If the delivery is limited to the same house, it is possible to set a restriction that the user must be in the same house at that time, and it can also be used to give a premium to viewing. Note that billing by the distribution server may be performed.

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

If the information stored in the broadcast signal indicates that the copyright protection is required by the predetermined method, and the copyright protection cannot be authenticated by the predetermined method, the terminal cooperation is not permitted. Further, even if 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 default method, the terminal cooperation is not permitted. Since the procedure after permitting the terminal cooperation is the same as the procedure shown in FIG. 18C, the description thereof will be omitted.

According to the mobile information terminal cooperation technique according to the present embodiment described above, it is possible to realize the use of the mobile information terminal linked with the broadcast receiving device from outside the house while paying attention to copyright protection.

In the actual usage situation, it is more desirable to easily know whether or not there is a terminal cooperation application by the program and which terminal cooperation application can be used. In this embodiment, a method of displaying the availability status of the terminal cooperation application will be described. The terminal cooperation application refers to a broadcasting 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 cooperation application (173b12 to 173b14) for the broadcast receiving device 100 linked to the program being viewed and a broadcast cooperation application (173b15 to 173b17) for the mobile information terminal are displayed. In the case of this example, the thickness of the border surrounding the character string and the color inside the frame indicate the status of the app. The main body application A, B (173b12, 173b13) and the terminal application A, B (173b15, 173b16) are available, and the main body application C (173b14) and the terminal application C (173b17) cannot be used. .. The state in which the terminal application cannot be used means that none of the mobile information terminals 700 in a state in which communication with the broadcast receiving device 100 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 mobile information terminal 700 with respect to the terminal application A is shown. The mobile information terminal displayed on this screen is a terminal that has been linked with or registered with the broadcast receiving device 100 in the past.

The mobile terminal 1 (173b22) and the mobile terminal 2 (173b23) whose icon border is a solid line are in a state of being able to communicate with the broadcast receiving device 100, and the mobile terminal 3 (173b24) whose border is a dotted line. And the mobile terminal 4 (173b25) are not in a state where they can communicate with the broadcast receiving device 100. Further, the mobile terminal 1 (173b22) and the mobile terminal 3 (173b24) whose icon frame is white have a function of executing the terminal application A, and the mobile terminal 2 (173b23) and the mobile terminal 4 whose frame is gray. (173b25) indicates that it does not have the function of executing the terminal application A. Furthermore, if the app is already running on the device, you may use an icon designed to indicate that.

In addition, the icon is easier to understand visually by using a pattern, so an example is shown below.

FIG. 19C is an example of a launcher screen (173b31) showing a list of broadcast cooperation applications. In addition to the broadcast receiving device 100, icons are shown for each type of mobile information terminal 700. 173b32 and 173b33 are icons indicating the broadcast receiving device 100, 173b34 and 173b35 are icons indicating a smart phone type personal digital assistant 700, and 173b36 is an icon indicating a head-mounted display type personal digital assistant 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 diagonal line mark in a circle) is displayed on the pattern of the device. Further, regarding the broadcast receiving device 100, if the application is already running, a mark indicating that fact (in this case, a dot in a circle) may be superimposed and displayed. With this display, it is possible to prevent a useless operation of advancing the launcher procedure even though the execution has already been performed. In the case of the mobile information terminal 700, it is also possible to display a mark indicating that the application is being executed on all terminals that are in a state of being able to communicate with the broadcast receiving device and that the application can be executed.

FIG. 19D is a screen (173b41) after selecting the application C (173b34) in FIG. 19C. The state of the mobile information terminal 700 of the type corresponding to the application C is shown. On this screen, if the mobile information terminal 700 does not have the execution function of the broadcast cooperation application, if it is not in a state where it can communicate with the broadcast reception device 100, or if the broadcast cooperation application is already being executed, that is indicated. The mark that represents it is displayed on top of the icon. In this example, a circle with diagonal lines (173b44, 173b46) if it does not have an execution function, a triangle with an exclamation mark (173b45, 173b46) if it is not in a communicable state, and a circle with a dot if it is already running. Mark (173b43) is displayed.

Furthermore, it is desirable to have a display method that shows that there is a broadcast cooperation application when the situation changes without starting the launcher each time. For example, when the power is turned on, when the channel is changed, when the broadcast cooperation application is changed at the beginning of the program or in the middle of the program, there is a change in the communication state between the broadcast receiving device 100 and the mobile information terminal 700. In that case, when the execution status of the application changes, the icon is displayed for a predetermined time and the status at that time is displayed.

FIG. 19E shows an example in that case. If an icon indicating the type of each device is displayed, it indicates that there is a broadcast cooperation application corresponding to the device of that type. In this case, the diagonal slash mark in the circle indicates that none of the devices of that type that are ready to run can run the app. A dot mark in the circle indicates that the app is running on all devices of that type that are ready for use.

FIG. 19F is a display screen (10401) on the mobile information terminal 700. When requesting terminal cooperation from the mobile information terminal 700, it is convenient to know from a list which broadcast cooperation application can be used with 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 examined. Further, if the status of each broadcast receiving device 100 is also displayed, the convenience is further enhanced especially when the broadcast receiving device 100 is used from outside the house. In this example, a display example such as receiving the program, receiving another program, vacant, and having a reservation for another program (when recording of another program is reserved from the middle of the program) is shown. Here, when a plurality of tuners exist in the broadcast receiving device 100, it is more convenient if the status is displayed for each of the plurality of tuners. In Table 10202, the branch numbers indicate the distinction between 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 cooperation, if the broadcast video and audio can be delivered as streaming data, it is not necessary to use the video unit of the broadcast receiver 100, and if the tuner in the broadcast receiver 100 can be used, the broadcast can be used. Therefore, it is convenient to know the usage status of each tuner.

In addition, in order to perform the display described in this embodiment, information on whether the application is compatible with the broadcast receiving device 100 or what type of mobile information terminal 700 is supported for each broadcast cooperation application. Must be. Further, the broadcast receiving device 100 and the mobile information terminal 700 need information for executing the corresponding application. Such information can be acquired by the broadcast receiving device 100 by describing it in AIT, for example.

According to the mobile information terminal cooperation technique 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 mobile information terminal 700. It becomes.

Hereinafter, Example 6 of the present invention will be described. The configuration and effects of this example shall be the same as those of Example 1 unless otherwise specified. Therefore, in the following, the differences between the present embodiment and the first embodiment will be mainly described, and the common points will be omitted as much as possible in order to avoid duplication.

In this embodiment, the operation of the broadcast receiving device 100 in the following cases, in particular, will be described with reference to the activation process of the broadcast cooperation application based on the AIT transmitted by the broadcast wave. In this case, the broadcast cooperation application is a broadcast managed application, and the broadcast managed application is a broadcast cooperation application based on the information on the PMT and the information such as the application control code 903 of the AIT and the activation priority 907 (FIG. 6). This is the case when the application is specified and instructed to start automatically with priority. In the following, a broadcast managed application may be referred to as a "broadcast managed application".

The broadcast receiving device 100 of the sixth embodiment has a function of controlling the activation process of the broadcast cooperation application for which the automatic activation is specified in the digital broadcasting service according to the selection by the user. When the broadcast receiving device 100 of the sixth embodiment has the above-mentioned automatic activation provision or instruction, the broadcast cooperation application is not unconditionally automatically activated, but is subject to the following conditions (1) to (3). Control to start automatically only when applicable. (1) When automatic startup is set to be acceptable in the user settings of the broadcast receiver. (2) When a user who has a predetermined terminal linked to the broadcast receiving device is watching, in other words, when the user setting of the linked terminal is set to allow automatic activation. (3) When the user is confirmed to start each time and the confirmation is affirmed.

FIG. 20 shows a system configuration and a usage example including the broadcast receiving device 100 of the sixth embodiment. The broadcast receiving device 100 receives broadcast waves from the broadcasting station server 300 via the radio tower 300t, and separates the video of the 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 the automatic activation of the broadcast cooperation application linked to the broadcast program.

There is one or more mobile information terminals 700 that cooperate with the broadcast receiving device 100. For example, one broadcast receiving device 100 can be linked with and shared with each of the mobile information terminals 700 of two users. For example, there is a terminal A owned by the user A and a terminal B owned by the user B. Not limited to this, one user may use a plurality of mobile information terminals 700.

The broadcast receiving device 100 of the sixth embodiment has an application activation control means 2000 including a user selection means 2001. The user selection means 2001 is a means for selecting whether or not to allow the activation and execution of the broadcast cooperation application based on the user's operation of the broadcast receiving device 100 and the mobile information terminal 700. The user selection means 2001 is composed of, for example, an instruction input unit, a user setting unit, and the like in the broadcast receiving device 100 and the mobile information terminal 700. When the automatic start of the broadcast cooperation application is instructed by the AIT, the application start control means 2000 responds to the selection of whether or not the user and the user selection means 2001 are allowed to start and execute the broadcast cooperation application. Controls the launch of linked apps.

[For automatic startup of broadcast managed apps]
In the sixth embodiment, when the broadcast managed application is first specified to be automatically started with priority, the broadcast receiving device 100 appropriately confirms information such as PMT and AIT and starts the broadcast managed application. The operation sequence of the above is the same as the description using FIG. 7A of the first embodiment. In the example of FIG. 7A, it is confirmed whether the target broadcast managed application can be executed by the broadcast receiving device 100 by confirming the application profile 904 of AIT (S105). When the execution is confirmed, the broadcast managed application is always automatically started regardless of the user's selection of the broadcast receiving device 100.

However, it should be considered that the user of the broadcast receiving device 100 does not want to automatically start the broadcast managed application, for example, because he / she wants to concentrate on watching the broadcast program. The broadcast receiving device 100 of the sixth embodiment has an application activation control means 2000 as a control function in consideration of this possibility. That is, when the broadcast receiving device 100 of the sixth embodiment is instructed to automatically start the broadcast managed application priority based on the information such as PMT and AIT, and when it is confirmed that the broadcast managed application can be executed by the information such as AIT. Also, the activation of the application is controlled according to the user's selection of whether or not to activate the application. Hereinafter, an example in which whether or not the broadcast managed application can be automatically started will be controlled will be described.

[Operation sequence when the broadcast managed application is started (1)]
FIG. 21 shows the activation of the broadcast cooperation application when the broadcast managed application, which is the broadcast cooperation application, is specified to be preferentially started as the first configuration example and the processing example of the broadcast receiving device 100 of the sixth embodiment. An example of the operation sequence of time is shown. FIG. 21 shows a series of flows until the broadcast receiving device 100 appropriately confirms the information of PMT and AIT, and further controls whether or not the predetermined broadcast cooperation application can be automatically started according to the user's selection. In the first configuration example, the user setting in the broadcast receiving device 100 is used as the user selection means 2000.

In FIG. 21, the broadcast receiving device 100 acquires 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 device 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 device 100 confirms that the activation priority of the broadcast managed application, which is a broadcast cooperation application, is high in the processing of S1101 and S1102.

Upon confirmation of the above, the broadcast receiving device 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). .. When the application control code 903 is "automatic start" in the processing of S1103 and S1104, that is, when the automatic start of the broadcast cooperation application is specified, the broadcast receiving device 100 further applies the acquired AIT data string application. Check profile 904 (S1105).

The broadcast receiving device 100 confirms in S1105 that the broadcast receiving device 100 can execute the broadcast cooperation application specified in the AIT by confirming the information of the application profile 904. When the enablement is confirmed, the broadcast receiving device 100 further refers to the operation setting value stored in the storage unit 110 by the application control unit 161. As a result, the broadcast receiving device 100 confirms whether or not the automatic activation of the broadcast cooperation application is permitted in the user settings of the broadcast receiving device 100 (S1106).

The operation setting value indicating whether or not the broadcast cooperation application can be automatically started can be selected and set by the user according to his / her preference from the function setting menu of the broadcast receiving device 100 or the like. The broadcast receiving device 100 provides the user with a function setting menu on a screen or the like as the user selection means 2001. The user can make user settings related to various functions by operating the remote controller of the broadcast receiving device 100, the linked mobile information terminal 700, or the like in the function setting menu of the screen. The broadcast receiving device 100 stores the user setting information in the function setting menu as an operation setting value in the memory in the broadcast receiving device 100.

When the broadcast receiving device 100 confirms in the process of S1106 that the automatic activation of the broadcast cooperation application is not permitted (“No”), that is, the user does not desire the automatic activation of the broadcast cooperation application (S1107). -No), this process of FIG. 21 is terminated. That is, the application control unit 161 does not acquire or start the broadcast cooperation application designated by the AIT.

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

The service provider server 400 that has received the distribution request of the broadcast cooperation application of S1108 performs authentication processing of the broadcast receiving device 100 as necessary based on the control of the application management / distribution execution unit 4103 of FIG. 4, and then performs authentication processing. 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 process, and detailed description thereof will be omitted.

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

As a modification, the processing of S1106 to S1107 may be performed after the broadcasting cooperation application is acquired by the processing of S1108 to S1109.

As in the first configuration example of FIG. 21 described above, in the sixth embodiment, the broadcast cooperation application can be started when the user setting of the broadcast receiving device 100 confirms that the automatic start is acceptable.

[Operation sequence when the broadcast managed application is started (2)]
FIG. 22 is a second configuration example and a processing example of the broadcast receiving device 100 of the sixth embodiment, in which the broadcast managed application, which is a broadcast cooperation application, is specified to be preferentially started. An example of the operation sequence at the time of starting a different broadcast cooperation application is shown. FIG. 22 shows whether or not the broadcast cooperation application can be automatically started by referring to the operation set in cooperation with the broadcast receiving device 100, that is, the operation setting value stored in the mobile information terminal 700 that performs the terminal cooperation described above, that is, the user setting information. This is an example of confirming. In the second configuration example, the user setting on the mobile information terminal 700 is used as the user selection means 2000. The user selects and sets whether or not to allow the automatic activation of the broadcast cooperation application for the mobile information terminal 700.

In FIG. 22, the broadcast receiving device 100 first performs the processing of S1201 to S1205, which is the same as the processing of S1101 to S1105 in FIG. When the broadcast receiving device 100 confirms that the broadcast cooperation application specified in the AIT can be executed by checking the application profile 904 in S1205, the broadcast receiving device 100 then performs the process of S1206. In S1206, the broadcast receiving device 100 transmits a user setting confirmation request to the mobile information terminal 700 in the linked operation by the application control unit 161. Here, it is assumed that there is, for example, the terminal A of FIG. 20 as the mobile information terminal 700 in the state of being linked or in a state where the terminals can be linked.

The mobile information terminal 700 receives an operation setting value for the broadcast receiving device 100 stored in the storage unit 710 of FIG. 5A 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. Refer to. As a result, the mobile information terminal 700 confirms whether or not the broadcast cooperation application can be automatically started in the broadcast receiving device 100 in the user settings of the mobile information terminal 700 (S1207). The mobile information terminal 700 transmits the confirmation result of whether or not the automatic activation is possible to the broadcast receiving device 100 via the LAN communication unit 721 as the user setting confirmation result by the cooperation control execution unit 7102 (S1208).

The operation setting value for whether or not to automatically start the broadcast cooperation application on the broadcast receiving device 100, which is the user setting information of the mobile information terminal 700, can be set by, for example, the following means. That is, in the linked operation state of the broadcast receiving device 100 and the mobile information terminal 700, the user selects and sets the link function setting menu, which is one of the function setting menus of the mobile information terminal 700, according to the user's preference. can. The mobile information terminal 700 provides the user with the above-mentioned function setting menu on a screen or the like. The user selects the linkage function setting menu from the function setting menu. The linkage function setting menu is a menu that allows settings related to linkage operation. The user can set whether or not to automatically start the broadcast cooperation application on the broadcast receiving device 100 by selecting from the cooperation function setting menu. The mobile information terminal 700 stores the user setting information in the function setting menu as an operation setting value in the memory in the mobile information terminal 700.

The broadcast receiving device 100 is not allowed to automatically start the broadcasting cooperation application through the processes of S1206 to S1208, that is, the user who owns the mobile information terminal 700 automatically starts the broadcasting cooperation application on the broadcast receiving device 100. When it is confirmed that it is not desired (S1209-No), the main process of FIG. 22 is terminated. That is, the application control unit 161 does not acquire or start the broadcast cooperation application designated by the AIT.

On the other hand, the broadcast receiving device 100 is allowed to automatically start the broadcasting cooperation application, that is, the user who owns the mobile information terminal 700 wants to automatically start the broadcasting cooperation application on the broadcasting receiving device 100. If confirmed (S1209-Yes), the process proceeds to S1210.

In S1210, the broadcast receiving device 100 requests the predetermined service provider server 400 to distribute the broadcast cooperation application 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. To send.

The service provider server 400 that has received the distribution request of the broadcast cooperation application of S1210 performs the authentication process 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. The predetermined broadcast cooperation application stored in the area 4013 is distributed via the LAN communication unit 421 (S1211).

Next, the broadcast receiving device 100 activates a predetermined broadcast cooperation application distributed from the service provider server 400, which is received by the application engine 162 via the LAN communication unit 121 based on the control of the application control unit 161. S1212).

As in the second configuration example of FIG. 22 above, in the sixth embodiment, there is a mobile information terminal 700 linked to the broadcast receiving device 100, and it is confirmed by the user setting of the mobile information terminal 700 whether or not automatic activation is possible. If so, you can start the broadcast cooperation application.

As a modification, when the user setting is confirmed in FIG. 22, if the mobile information terminal 700 is not in the linked operation with the broadcast receiving device 100, S606 to S611 in FIG. 8C is performed before the processing of S1206 to S1208. May be processed. As a result, in this modification, the cooperation control application is started, the mobile information terminal 700 is started to cooperate with the broadcast receiving device 100, and the user setting is confirmed in this state.

Further, as a modification, in the following cases, an embodiment in which the Yes side is controlled to be selected in S1209 and an embodiment in which the No side is controlled to be selected in S1209 are possible. In this case, there is no mobile information terminal 700 to which the user setting confirmation request is transmitted in S1206, there is no response to the request, the user setting confirmation result cannot be correctly acquired in S1208, and the like. This case corresponds to a situation where there is no mobile information terminal 700 capable of terminal cooperation at that time, a situation where communication between the broadcast receiving device 100 and the mobile information terminal 700 is temporarily impossible, and the like. In the former embodiment, the permission to start by the user setting could not be confirmed, but the broadcast cooperation application is started. In the latter embodiment, since the permission for activation by the user setting could not be confirmed, the broadcast cooperation application is not activated. Which control operation is adopted in the above modification is defined by the specifications of the broadcast receiving device 100, or can be selected by the user.

Further, as a modification, the processing of S1206 to S1209 may be performed after the broadcasting cooperation application is acquired by the processing of S1210 to S1211.

[Operation sequence when the broadcast managed application is started (3)]
FIG. 23 shows a further different broadcast cooperation when the broadcast managed application, which is a broadcast cooperation application, is specified to be preferentially started as a third configuration example and processing example of the broadcast receiving device 100 of the sixth embodiment. An example of the operation sequence at the time of starting the application is shown. FIG. 23 is an example of confirming to the user in real time whether or not the broadcast cooperation application can be started by a message on the screen or the like each time. In the third configuration example, the instruction input from the mobile information terminal 700 to the broadcast receiving device 100 is used as the user selection means 2000.

In FIG. 23, the broadcast receiving device 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 device 100 confirms that the broadcast cooperation application specified in the AIT can be executed by checking the application profile 904 in S1205, the broadcast receiving device 100 then performs the process of S1306. In S1306, the broadcast receiving device 100 displays on the video display unit 173 a startability confirmation screen for allowing the user to select whether or not to allow the start of the broadcast cooperation application by the application control unit 161.

The user selects whether or not to activate the broadcast cooperation application by using the mobile information terminal 700, the remote controller, or the like, which is an operating means, on the activation availability confirmation screen displayed in S1306 (S1307). The broadcast receiving device 100 receives the information of the selection as an instruction input.

When the broadcast receiving device 100 does not select to start the broadcast cooperation application according to the result of the start enable / disable selection by the user of S1307, that is, when the user does not allow the start at this point (S1308-No), the broadcast receiving device 100 does not allow the start. This process of FIG. 23 ends. That is, the application control unit 161 does not acquire or start the broadcast cooperation application designated by the AIT.

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

The service provider server 400 that has received the distribution request of the broadcast cooperation application performs the authentication process of the broadcast receiving device 100 as necessary based on the control of the application management / distribution execution unit 4103, and then the application storage area 4013. The predetermined broadcast cooperation application stored in is distributed via the LAN communication unit 421 (S1310).

Next, the broadcast receiving device 100 activates a predetermined broadcast cooperation application distributed from the service provider server 400, which is received by the application engine 162 via the LAN communication unit 121 based on the control of the application control unit 161. S1311).

As a modification, the processing of S1306 to S1308 may be performed after the broadcasting cooperation application is acquired by the processing of S1309 to S1310.

As in the third configuration example of FIG. 23 described above, in the sixth embodiment, the user can be confirmed to start the application on the screen each time, and when the acceptance is confirmed, the broadcast cooperation application can be started.

In the example of FIG. 23, the mobile information terminal 700 is made to function as an operation means of the broadcast receiving device 100 by the terminal cooperation, and the activation possibility is selected. Not limited to this, there is also an embodiment in which the startability is selected by using a remote controller or the like provided in the broadcast receiving device 100 which is the main body.

[Startup availability confirmation screen]
FIG. 24 shows an example of a startability confirmation screen of the broadcast receiving device 100 displayed by the process of S1306 of FIG. In this embodiment, a message box 173f1 is displayed on the screen of the video display unit 173 of FIG. 24 as a startability confirmation screen. The message box 173f1 includes a message that the predetermined broadcast cooperation application can be used, and display of "Yes" and "No" buttons for selecting whether or not to start the broadcast cooperation application. An example of a message is "A broadcast cooperation application XXX can be used. Do you want to start the broadcasting cooperation application XXX?" Another example of the message is "The broadcast cooperation application XXX is specified to be started and can be started. Do you want to allow the start?"

In the state where the message box 173f1 shown in FIG. 24 is displayed, the user selects whether or not to start using the above operating means (S1307). For example, the user selects the above-mentioned "Yes" or "No" on the basic screen 741a of the cooperation control application of the mobile information terminal 700 of FIG. 10A by using the cursor key 741ac, the enter key 741ad, and the like. As a result, the user can select whether or not to allow the activation of the broadcast cooperation application presented in the message box 173f1 on the broadcast receiving device 100 according to his / her own convenience and situation at that time.

As a modification, instead of the message box 173f1, the icon 173b0 indicating the presence of the linked application as shown in FIG. 12A, or other marks, images, etc. are displayed on the screen so that the user can select the operation. May be good. In this case, the user presses, for example, 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. Further, if the linked application key 741a9 corresponding to the selection of the icon 173b0 is not pressed for a predetermined time or more, the display of the icon 173b0 may be controlled to be erased.

[Effects, etc.]
As described above, according to each configuration example of the broadcast receiving device 100 of the sixth embodiment, it has been confirmed that there are provisions and instructions for automatic activation of the broadcast managed application priority by PMT and AIT, and that the broadcast managed application by AIT can be executed. Even in this case, the activation of the broadcast managed application can be appropriately controlled according to the user's selection. That is, according to the broadcast receiving device 100 of this embodiment, it is possible to execute a function having higher added value.

It should be noted that which of the first to third configuration examples and various modifications to be adopted is specified as the specifications of the broadcast receiving device 100 or the like, or the user's selection setting for the broadcast receiving device 100 or the like is set. Make it possible. For example, in the configuration examples of FIGS. 21 and 22, the operation setting values set by the user are (a) "allowing the start of the broadcast managed application (possible)" and (b) "not allowing the start of the broadcast managed application (no). ) ”Can be selected from the two values. Not limited to this, as a modification, in addition to the above (a) and (b), multiple values including (c) "contact the terminal" and (d) "confirm on the screen each time" are included in the user settings. It may be possible to select from. The broadcast receiving device 100 of this modification performs a control operation according to the first to third configuration examples corresponding to the set value selected by the user. In the case of the setting (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 cooperation application according to the user's settings in advance for the broadcast receiving device 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 of displaying a menu for user setting on the screen of the broadcast receiving device 100. The menu 173f2 for user setting is displayed on the screen according to the operation of the remote controller or the like by the user. In the case of the first configuration example, the menu 173f2 has "allowing the activation of the broadcast managed application" as one of the setting items. The 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 the button on / off or the like in the setting item of the menu 173f2. The same function can be realized on the screen of the mobile information terminal 700.

In particular, in the second configuration example of FIG. 22, it is possible to set whether or not to automatically start the broadcast managed application for each user who owns the mobile information terminal 700, and further, broadcasting depending on the presence or absence of the mobile information terminal 700 that performs cooperative operation. 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. 20 described above. As a user setting in the mobile information terminal 700, the terminal A of the user A has the setting A, and the terminal B of the user B has a different setting B. For example, in setting A, the automatic start of the broadcast cooperation application is "possible", and in setting B, the automatic start of the broadcast cooperation application is "no". At the time of processing S1206 to S1209 in FIG. 22, for example, if only the terminal A of the user A is operating in cooperation, the result is that the terminal A is confirmed and the activation is permitted. If only the terminal B of the user B is operating in cooperation, the result is that the terminal B is confirmed and the activation is not permitted. In this way, it is possible to set whether or not to start the broadcast cooperation application for each user's mobile information terminal 700, and it is possible to start and use the broadcast cooperation application according to the presence or absence of the mobile information terminal 700 to be linked in the situation at that time. be.

Further, as a modification, it is possible to perform a control operation in consideration of a combination of the specifications or user settings of the broadcast receiving device 100 and the specifications or user settings of the mobile information terminal 700. For example, an embodiment in which the content of the user setting on the mobile information terminal 700 is prioritized over the user setting on the broadcast receiving device 100, and the content of the user setting on the broadcast receiving device 100 is prioritized over the user setting on the mobile information terminal 700. Any of the examples is possible.

Further, in the second configuration example, it may be possible to make a user setting regarding whether or not to inquire the mobile information terminal 700 to confirm whether or not the broadcast cooperation application can be started. In that case, the menu 173f2 for user setting in FIG. 25 is provided with a setting item corresponding to the "contact terminal" in (c) above.

In particular, in the third configuration example of FIG. 23, it is possible to control whether or not the broadcast managed application prepared for each broadcast program can be activated. The user can see the broadcast managed app and confirmation information presented on the screen and allow the app to start if he wants to start it at that time, and disallow it if he does not want to start the app at that time. ..

Further, in the third configuration example, it may be possible to make a user setting regarding whether or not to confirm whether or not to start the broadcast cooperation application on the screen each time. In that case, in the user setting menu 173f2 of FIG. 25, a setting item corresponding to the "confirm on the screen each time" of the above (d) is provided.

Other examples include: In another embodiment, the broadcast managed application is forced regardless of the set value even when the above (b) is selected and set in advance in the user settings in the configuration examples of FIGS. 21 and 22. Prepare an option to start the application. In this embodiment, for example, in the AIT data structure shown in FIG. 6, in addition to (1) to (4), the setting value of (5) "forced start" is prepared as the setting value of the parameter of the application control code 903. do. Alternatively, separately, an item of "forced start setting" may be prepared as one of the parameters of AIT (one of "other information" in FIG. 6). For these setting values, for example, "valid" and "invalid" can be selected.

Further, when the setting value of the application control code 903 is "forced start" in (5) above, or when the value of the item of the above "forced start setting" is "valid", the broadcast receiving device 100 receives the broadcast receiver 100. It is controlled as follows. That is, the broadcast receiving device 100 controls to forcibly start the broadcast managed application even when the operation setting value is set to No (b). In other words, the control of this embodiment is provided with forced activation as a higher-level and priority item than the above-mentioned user-selected item regarding automatic activation. In the case of an embodiment provided with the forced activation option as described above, there is a high need for display and provision of, for example, an application for displaying emergency information from the broadcasting station side or an application necessary for producing a specific CM. The application can be suitably displayed and provided to the user.

As another embodiment, when the broadcast cooperation application is pre-installed inside the broadcast receiving device 100, processing such as acquisition of the broadcast cooperation application for the service provider server 400 described above (for example, S1108 to S1110 in FIG. 21). ) Is no longer necessary.

The information included in the broadcast wave for controlling the broadcast cooperation application is applicable not only to PAT and AIT. For example, one of the AIT parameters (901 to 909) 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 preset in the device.

Hereinafter, Example 7 of the present invention will be described. The configuration and effects of this example shall be the same as those of Example 1 unless otherwise specified. Therefore, in the following, the differences between the present embodiment and the first embodiment will be mainly described, and the common points will be omitted as much as possible in order to avoid duplication.

Since the broadcast cooperation application, which is an application used in the broadcast communication cooperation system of this embodiment, is composed of HTML documents, it can be linked with other HTML documents on the network. The broadcast managed application is controlled to start / stop and the like based on the AIT application control code 903 and the like included in the broadcast signal of the broadcast wave. Operations such as start / end of non-broadcast managed applications and general applications are not controlled by the above-mentioned broadcast signal. Hereinafter, the non-broadcast managed application may be referred to as a “non-broadcast application”, and the general application may be referred to as a “general application”.

Since it is possible to link in the HTML document constituting the broadcast cooperation application, it is assumed that the transition from the broadcast managed application to the non-broadcast application or the general application is possible in the seventh embodiment. Further, in the seventh embodiment, it is also possible to directly activate the non-broadcast application or the general application from the above-mentioned broadcast cooperation application launcher screen or the like in response to a user's instruction operation. For example, a broadcasting station, a service provider, or the like includes information on a transition to another HTML document constituting a non-broadcasting application or the like by describing a link such as a URL in the HTML document of the broadcasting managed application. .. In such a case, a transition from the broadcast managed application to a non-broadcast application or the like may occur.

Since the operations such as start / end of the non-broadcast application and the general application are not controlled 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 executing the non-broadcast application or the like while watching the broadcast program, the activation of the broadcast managed application linked to the broadcast program may be further requested. The request includes, for example, an instruction to activate the AIT application control code 903 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. Although it is technically possible to execute multiple applications of different types in parallel in this way, it may not be desirable in terms of control and may be inconvenient for the user.

Therefore, the broadcast receiving device 100 of the seventh embodiment has a function of controlling duplication or parallel activation of the applications or activation and termination of each application so that the above situation can be appropriately dealt with. When the start and execution of the second application are requested while the first application is being executed, the function controls the operation including the start and end of those applications according to the user's selection. In particular, this function terminates the non-broadcast application or activates the broadcast managed application according to the user's instruction input or setting when a request to start the broadcast managed application arrives while the non-broadcast application is being executed. Control. In the seventh embodiment, an example of the control operation of the broadcast receiving device 100 in the above cases and situations will be described.

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

The means of user selection by the above function is as follows. (A) The above functions include information that informs the user of the status of a request to start a broadcast managed application other than the running non-broadcast application, etc., and an application that starts or terminates the above request. Alternatively, information for allowing the user to select the operation of the above control is displayed on the screen. The function accepts an operation of inputting a selection instruction by the user on the 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 above function accepts a user setting operation by the user in advance. When the above request comes, the function executes, for example, the content of the control selected from the above (1) to (3) according to the confirmation of the user setting information.

FIG. 26 shows a system configuration and a usage example including the broadcast receiving device 100 of the seventh embodiment. The broadcast receiving device 100 receives broadcast waves from the broadcasting station server 300 via the radio tower 300t, and separates the video of the broadcast program from information such as AIT. The broadcast receiving device 100 appropriately acquires a broadcast managed application, which is a broadcast cooperation application, from a service provider server 400 or the like based on information such as AIT. Further, the broadcast receiving device 100 appropriately acquires non-broadcast applications and general applications from the service provider server 400, other application servers 500, and the like. Further, there may be a mobile information terminal 700 that cooperates with the broadcast receiving device 100, and various applications are acquired and executed in the state of terminal cooperation between the broadcast receiving device 100 and the mobile information terminal 700. May be good.

The broadcast receiving device 100 of the seventh embodiment has a plurality of application execution control means 2600 including a user selection means 2601. The user selection means 2601 is a means for selecting the content of control such as operation including start and end of a plurality of types of applications, parallel execution, etc., based on the user's operation of the broadcast receiving device 100 and the mobile information terminal 700. .. The user selection means 2601 includes, for example, an instruction input unit for receiving and processing instruction input in the broadcast receiving device 100, the mobile information terminal 700, and the like according to the above (a). The user selection means 2601 includes, for example, a user setting unit related to the above (b) that accepts and processes user settings.

The plurality of application execution control means 2600 is based on the user and the user selection means 2601 when, for example, the user and the user selection means 2600 are instructed to start the broadcast managed application by the broadcast wave AIT while the non-broadcast application or the general application is being executed while watching the broadcast program. , Controls the termination of non-broadcast applications, the activation of broadcast managed applications, etc., according to the selection of the control operation corresponding to the case.

[Examples of multiple types of apps]
FIG. 27 shows an example of document configuration of a plurality of types of applications, activation of each application, transition between each application, and the like. 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 device 100 of the existence of the broadcast cooperation application and instructs the control such as activation and termination thereof. For example, the broadcast managed application 2011 is activated by the information of AIT included in the broadcast wave 2010.

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

In FIG. 27, the broadcast managed application 2011, App1, is composed of, for example, four documents, HTML11 to HTML14. The non-broadcast application 2012, App2, is composed of, for example, two documents, HTML21 to HTML22. App3, which is a general application 2013, is composed of, for example, two documents, HTML31 to HTML32. Each HTML document can be transitioned by the link indicated by the solid arrow. For example, it is possible to transition from HTML13 of App1 to HTML21 of App2 and HTML31 of App3. Dashed arrows show examples of transitions between HTML documents.

In FIG. 27, for example, in response to the user operation 2020 on the above-mentioned broadcast cooperation application launcher screen, the non-broadcast application 2012, Appp2, and the general application 2013, Appp3, can be activated. App2 is executed, for example, by reading HTML21, and App3 is executed, for example, by reading HTML31.

The following is an example of the case where each application is independently executed during the reproduction of a broadcast program (for example, broadcast program A) by the broadcast wave 2010. (A1) The AIT instructs to start the broadcast managed application 2011, and the app1 is started and executed. App1 is allowed access to the broadcast program A. Then, when the end of App1 is instructed by the same AIT, Appp1 is terminated.

(A2) Based on the operation of selection such as input of instructions by the user, the start of the non-broadcast application 2012, Appp2, is instructed by the broadcast cooperation application launcher screen, the link from HTL13 of App1, and the like, and App2 is started and executed. Will be done. App2 is allowed access to the broadcast program A. When the end of App2 is instructed, App2 is terminated. (A3) Similarly, based on the user's selection operation, the start of the general application 2013, Appp3, is instructed by the broadcast cooperation application launcher screen, the link from HPM13 of App1, and the like, and App3 is started and executed. .. App3 is not allowed access to broadcast program A. When the end of App3 is instructed, App3 is terminated.

[Operation sequence when the broadcast managed application is started]
FIG. 28 shows a control operation sequence in the broadcast receiving device 100 of the seventh embodiment when the start of the broadcast managed application is requested by the AIT of the broadcast signal or the like while the non-broadcast application is being executed while the broadcast program is being viewed. show. In the following, the case of a non-broadcast application will be described, but the same is possible for a general application. In FIG. 28, it is assumed that the start of the broadcast managed application priority is specified and instructed by the information on the PMT and the information such as the application control code 903 of AIT and the start priority 907.

In the broadcast receiving device 100, while the user is watching a broadcast program, for example, the user is instructed to start the non-broadcast application in response to an operation of selecting an arbitrary desired non-broadcast application from the broadcast cooperation application launcher screen. Then, the broadcast receiving device 100 superimposes and displays, for example, the execution screen of the non-broadcast application on the broadcast program screen (S1401). When the broadcast program is switched in the state of S1401, the contents of information such as PMT and AIT in the broadcast signal are updated. Even if the update is performed, the non-broadcast application is not controlled by the broadcast signal for operations such as start / end, so that the execution state is continued.

Next, the broadcast receiving device 100 acquires the PMT data string separated by the first separation unit 132 by the main control unit 101 (S1402), and confirms the activation priority described in the PMT (S1403). In the process of S1403, for example, it is confirmed that the activation priority of the broadcast managed application is high. Then, the broadcast receiving device 100 acquires the AIT data string separated by the first separation unit 132 by the application control unit 161 (S1404), and confirms the application control code 903 of the acquired AIT data string (S1405).
