[Overview of Application Control Information (AIT)]
The application control information (AIT) of this embodiment is an application (AIT) linked to a broadcast service with respect to a television receiver or the like (in this embodiment, the broadcast receiver 100) in the broadcast communication linkage function supported by the broadcast receiver 100. Hereinafter, it may be referred to as a broadcast cooperation application.) It is assumed that the information is intended to inform the existence of the existence and instruct its control. The broadcast cooperation application operates only in the broadcast reception state based on (1) a control signal such as start / end included in the broadcast signal, and access to the broadcast resource is permitted based on the control signal. Applications, non-broadcast managed applications that allow access to broadcast resources based on means such as application authentication in an operation mode in which the start / end is not controlled by the broadcast signal, and (3) broadcast resources. It may be distinguished from other general applications that are not allowed access.

As the transmission method of AIT, a method of transmitting AIT in section format or XML (XML (XML) Language) format by broadcast wave by a data carousel (Data Carousel: DC) method, and a method of transmitting the AIT file in section format or XML format on the Internet. Either a method of delivering data from the server device on the 200 by http (Hypertext Transmission Protocol) or https (Hypertext Transmission Protocol) may be used. Other methods may be adopted.

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

Application type 901 defines an application description scheme. In this embodiment, it is assumed that the description method of the application is HTML. The application identifier 902 is identification information for identifying an application unit, which is composed of an organization identification for identifying a business operator and an application identification numbered for each business operator. The application unit is a set of HTML documents and their reference resources whose entry documents are HTML documents existing at the location specified in the application acquisition destination information 905. The application control code 903 defines the operation control for the target application, and one of (1) automatic start, (2) operable, (3) termination, and (4) prefetch is described. .. 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. The availability of the application is determined by referring to this value.

The application acquisition destination information 905 is information for specifying the acquisition destination of the application, and is location information for acquiring 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 on a server device on the communication network, the location information specified in 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 specifies 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. To do. In addition, it is possible to set the access authority to a specific broadcasting resource in each area within the range of the document transition.

The activation priority 907 defines which of the data broadcasting by the broadcasting service and the broadcasting managed application by the HTML document is 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. Suppose it is 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. The television receiver may operate to stochastically delay the application of the application control code according to the setting of this parameter.

Hereinafter, the operation of the broadcast receiving device 100 of this embodiment will be described.

[Operation sequence when application starts]
First, the activation process of the broadcast cooperation application based on the AIT transmitted by the broadcast wave in the broadcast receiving device 100 of this embodiment will be described. In the broadcast receiving device 100 of this embodiment, which is prioritized when the data broadcasting by the broadcasting service and the broadcasting cooperation application exist at the same time based on the information on the PMT, the application control code 903 of the AIT, the activation priority 907, and the like. 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 started with priority. 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, the main control unit 101 then 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 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 enters the application storage area 4013. Distribution of the stored predetermined broadcast cooperation application is performed 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 the operation sequence of the broadcast cooperation application when it is specified to preferentially start the data broadcasting by the broadcast service. The figure shows a series of flow until the broadcast receiving device 100 appropriately confirms the PMT and the AIT and activates the 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, the main control unit 101 then 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, and when the user makes a data broadcasting start request 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, an entry button for the executeable broadcast cooperation application is displayed on the data broadcasting screen. The entry button may be displayed at all times, 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 of 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 broadcast receiving device 100 in the application storage area 4013. The stored predetermined broadcast cooperation application is distributed via the LAN communication unit 421 (S212). Next, the application engine 162 of the broadcast receiving 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 the AIT and activates the 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, the main control unit 101 then 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 start 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 after the processing of S304 is completed (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. Acquire (S311), and confirm 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 broadcast receiving device 100 in 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 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 on the PMT at the same time, 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 regularly 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, priority may be given to activation of data broadcasting by the broadcasting service.

If there is no response from the service provider server 400 for a predetermined time or more when a distribution request for the broadcast cooperation application is made in S106, S211, and 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 asking 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. For example, by installing an application (cooperation control application) prepared by the manufacturer of the television receiver, the mobile information terminal 700 can be used as a high-performance remote controller of the broadcast receiving device 100. 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 order to expand the functions by the cooperative operation of 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 advance in the storage unit 710 of the mobile information terminal 700 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 communicating (cooperation operation) on the network (S401). 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.

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 the broadcast cooperation application is acquired from the network, the network connection status is naturally confirmed in advance, but at this time, for example, the broadcast cooperation application is acquired 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, when the predetermined optional function is insufficient on the TV receiver side, an 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 represents 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, the program title of each broadcast program and symbols representing the attributes of each broadcast program are displayed. The symbols 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 checking 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 broadcasting cooperation application is prepared, can further cooperate 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".

It should be noted that the presence or absence of the display of the mark symbolizing "Linkage" and the mark symbolizing "Mobile" is described in advance in the EIT information including the 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 guide created based on the program information data string acquired from the broadcast wave of the digital broadcast service. It may be added.

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. In addition, 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 moved 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 process, when the broadcast program for which the viewing reservation and / or the recording reservation has been 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. In this way, 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 used 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 process 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 acquisition destination information (location information such as URL) of the broadcasting 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 the acquisition sequence of the broadcast cooperation application when the viewing reservation and / or the recording reservation of the broadcast program 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 broadcast receiving device 100 in 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 distributed from the service provider server 400 received via the LAN communication unit 121 in the RAM 104 or the storage 110 (S709).

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

Hereinafter, Example 2 of the present invention will be described. Unless otherwise specified, the configuration and effects of this example shall be the same as those of Example 1. 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 limitation). 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 to determine 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 apps 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, a 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, there are a plurality of methods for confirming the existence in the same house, but which method is 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 expired, 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.

Furthermore, 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 broadcasting cooperation application or the information used in the broadcasting cooperation application (hereinafter, the information used in the broadcasting cooperation application and the broadcasting cooperation application, specifically. These are HTML documents and streaming video, but these are collectively referred to as broadcast cooperation information). There are two types of methods for acquiring broadcast cooperation information: 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 or not the target mobile information terminal application has the same in-home restriction (S10006), and if there is a restriction, the procedure proceeds to S10008, and the first stage when the terminal cooperation request is made. Then, the process proceeds to step S10009, and it is determined whether or not the mobile information terminal 700 for which the terminal cooperation request has been made is in the same house as the broadcast receiver 100 (S10009). 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 broadcasting 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. In this service (S10012), the broadcast cooperation information distribution request (S10013) from the mobile information terminal 700 is processed, and the broadcast cooperation information is distributed 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 that the cooperation is not permitted is sent 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 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 mobile information terminal 700, and the entire distribution server in the section indicated by the arrow in 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 into 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 incorporated in 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 mobile information terminal 700 receives the broadcast every preset effective 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 restrictions. Furthermore, by using the authentication information incorporated 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 You can also confirm that you are continuing to watch.

According to the mobile information terminal cooperation technology 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 started.

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 latter 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 or not the application is a broadcasting cooperation application having the same in-home restriction (S10111), and if there is a restriction, the procedure proceeds to the next procedure S10112, and if not, the procedure of S10112 Skip to S10114. If all the broadcast cooperation apps 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 requesting mobile information terminal 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 cooperation 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 is requested to issue an authentication key 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 effective 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, once the authentication is performed, the authentication may be valid while watching the program.

Further, the authentication information described in the AIT may be incorporated into 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 incorporated in 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, a notification of the change may be issued from the broadcast signal (S10110), and the broadcast cooperation information may be acquired as a trigger. In that case, if the acquisition is 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 change notification may be notified. 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 ends (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 the authentication of the distribution server and managing the valid time, it can be confirmed that the mobile information terminal 700 is periodically in the same house as the broadcast receiving device 100. It is possible to appropriately execute a broadcast cooperation application that has the same in-home restrictions. Furthermore, by using the authentication information incorporated 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 You can also confirm that you are continuing to watch.

According to the mobile information terminal cooperation technology 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 the second and third embodiments, the procedure for realizing the same in-home restriction in the terminal cooperation has been described, but the use from outside the home may be permitted depending on the broadcasting cooperation application. In this embodiment, such a case will be described. For example, when a program such as TV shopping is publicity / 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, convenience is further enhanced 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 streaming data may be encrypted by the broadcast receiving device 100 for copyright protection. Whether or not the broadcast cooperation application permits the 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 there is a terminal cooperation request (S10203) from outside the home, the broadcast receiving device 100 confirms that 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 be authenticated 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 on 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, the broadcast receiving device 100 follows a predetermined method predetermined. 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 authentications may be performed. Alternatively, a plurality of authentications exemplified below may be combined. In addition, the authentication illustrated below may be combined 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 of encryption key]
In addition to the above-mentioned authentication using the ID and password, 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).

[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. 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 the authentication on the distribution server to authenticate the copyright protection, or the mobile information terminal. The authentication may be completed by notifying the broadcast receiving device 100 that the encryption key has been obtained from the 700. 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 copyright protection is required by a predetermined method, and if the copyright protection cannot be authenticated by the predetermined method, 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, 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 (S10210) from the above, the broadcast cooperation information is distributed to the personal digital assistant 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 the broadcast cooperation information from the distribution server by 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, once the authentication is performed with the mobile information terminal in the same house. 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.

The 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 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 be authenticated for copyright protection 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, the broadcast receiving device 100 follows a predetermined method predetermined. 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 authentications may be performed. Alternatively, a plurality of authentications exemplified below may be combined. In addition, the authentication illustrated below may be combined with other authentication processes not exemplified below.

[Use of 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 can only be obtained from the broadcast signal at a certain point in the program and the delivery 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. Limits 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. 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 the authentication on the distribution server to authenticate the copyright protection, or the mobile information terminal. The authentication may be completed by notifying the broadcast receiving device 100 that the encryption key has been obtained from the 700. 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 some 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 at home or outside the house.

If the information stored in the broadcast signal indicates that copyright protection is required by a predetermined method, and if the copyright protection cannot be authenticated by the predetermined method, 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 technology 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 depending on 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 broadcasting 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 application. 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 of being able to communicate 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 borders are solid lines are in a state where they can 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 of being able to 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 personal digital assistant 700. 173b32 and 173b33 are icons indicating the broadcast receiving device 100, 173b34 and 173b35 are icons indicating the smartphone type mobile information terminal 700, and 173b36 is an icon indicating the head-mounted display type mobile information terminal 700. Each app is for the device indicated by the icon.

In FIG. 19C, when the application cannot be used, a mark indicating the inability to use (in this case, a diagonal line mark in a circle) is displayed overlaid 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 it has already been executed. 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 to be represented is displayed over the icon. In this example, a circle with diagonal lines (173b44, 173b46) if it does not have the 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 one by one. For example, when the power is turned on, the channel is changed, the broadcast cooperation application is changed at the beginning of the program, or during the program, the communication state between the broadcast receiving device 100 and the mobile information terminal 700 changes. In that case, when the execution status of the application changes, the icon is displayed for a predetermined time and the state at that time is displayed.

FIG. 19E shows an example in that case. If an icon indicating the type of each device is displayed, it indicates that there is a broadcasting cooperation application corresponding to the device of that type. In this case, the diagonal slash mark in the circle indicates that there is no device of that type that is ready to run the app. A dot mark in the circle indicates that the app is running on all devices of that type that are available.

FIG. 19F is a display screen (10401) on the personal digital assistant 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. An example of the list is shown in FIG. 19F (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 are present 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. In addition, information for executing the corresponding application is required on the broadcast receiving device 100 and the mobile information terminal 700. This information can be acquired by the broadcast receiving device 100 by describing it in AIT, for example.

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

Hereinafter, the broadcast receiving device 100 of the sixth embodiment of the present invention will be described. The configuration and effects of this example shall be the same as those of Examples 1 to 5 unless otherwise specified. Therefore, in the following, the differences between the present embodiment and the first to fifth embodiments will be mainly described, and the common points will be omitted as much as possible to avoid duplication.

In the above Examples 1 to 5, the activation of the broadcast cooperation application has been mainly described, but the broadcast cooperation application is composed of, for example, one or more HTML documents as described above. That is, it is possible to make a transition between HTML documents by a link.

FIG. 20 shows the concept of transition of a broadcast cooperation application and an HTML document. FIG. 20A shows an example of the transition between documents in the application boundary 20101 of the broadcast cooperation application 20110 and the application boundary 20101.

In FIG. 20A, from the state in which the broadcast receiving device 100 is receiving the video by the broadcast signal as described above, or the state in which the BML document is executed and the data broadcasting screen information is displayed (20000). App1 which is a broadcasting cooperation application 20110 is started. The start of the broadcast cooperation application 20110 is automatically started by AIT or is instructed by the user. When the broadcast cooperation application 20110 is started, HTML1 which is the first HTML document 20111 which is an entry document is executed.

The broadcast cooperation application 20110, App1, is composed of HTML1 to HTML4, which are the four HTML documents 20111 to 20114 shown in the figure. In (a), the application boundary 20101 of the broadcast cooperation application 20110 is configured by the four HTML documents 2011 to 20114. The application boundary indicates the boundary of the region where the transition is possible, and is set in the AIT as an aggregate of one or more regions. Here, the area is an HTML document.

Further, each HTML document has a link to another HTML document, and the link enables a transition between each HTML document. The solid arrow indicates the transition link. The dashed arrow shows an example of performing a transition. In the example of (a), it is possible to make a bidirectional transition between all HTML documents. Not limited to this, there are cases where only a transition to a specific HTML document is possible, or a transition in only one direction is possible.

The above application boundary may be changed during application execution. Therefore, the HTML document that was within the range of the application boundary at the start of execution may be out of the range of the application boundary because the application boundary is changed in the middle.

FIG. 20B shows an example of the application boundary 2022 after the application boundary is changed from the state of (a) and the transition related to the application boundary 2022. The modified application boundary 2022 is composed of two documents, HTML document 20111 and HTML document 20112. In the application boundary 2022, bidirectional links between two documents allow transitions to each other.

For example, the application boundary 20201 is dynamically changed to the application boundary 2022 of (b) during execution of the HTML document 20113 of FIG. 20 (a). In this case, the HTML document 2013 is outside the scope of application boundary 2022.

An example of the dynamic change of the application boundary is to change the information of the AIT content of the broadcast signal so that the broadcasting station changes the application boundary according to the broadcast content.

Since the above change of the application boundary is not intended by the user, the user does not know the timing of the change or the state of the application boundary after the change. Therefore, the broadcast receiving device 100 of the sixth embodiment has a function of controlling the operation as follows.

FIG. 21 is a flowchart showing an operation sequence of the broadcast receiving device 100 of the sixth embodiment. This flowchart shows an operation when executing an HTML document (for example, HTML1 to HTML4) of the broadcast cooperation application 20110 of FIG. 20.

When executing the HTML document of the broadcast cooperation application, the broadcast receiving device 100 first reads the HTML document (S2001) and executes the read HTML document (S20002). That is, step S20002 is the execution of the broadcast cooperation application, which is the same operation as in Examples 1 to 5 described above.

After step S20002, the operation characteristics of the broadcast receiving device 100 of the sixth embodiment are shown. The broadcast receiving device 100 of the sixth embodiment performs a process of confirming the presence / absence of interrupt processing after S20002 (S20003). The interrupt processing referred to here is the termination of the broadcast cooperation application, the transition to another HTML document in the application boundary, the execution of another broadcast cooperation application, and the like. When there is an interrupt process (S20003-Yes), the broadcast receiving device 100 ends the main process of FIG. 21 and starts an operation corresponding to the interrupt process. Here, the description of the operation corresponding to the interrupt processing will be omitted.

When there is no interrupt processing (S20003-No), the broadcast receiving device 100 checks whether the HTML document being executed is within the range of the application boundary (S20004). When the HTML document being executed is not within the range of the application boundary, in other words, when it is outside the range of the application boundary (S2004-No), the broadcast receiving device 100 is not within the range of the application boundary on the video display unit 173. In other words, the mark 20200 indicating that it is out of the range is displayed (S20005).

If the application boundary is within the range of the application boundary in step S20004 (S20004-Yes), the mark 20200 is hidden (S20008), and the process returns to step S20003. The broadcast receiving device 100 continuously and repeatedly executes the check process of S20004 by the loop returning to S20003 during the execution of the HTML document of the broadcast cooperation application 20110.

The process of S20004 may be a periodic process, for example, a process executed once every few seconds, or a process executed when the HTML document is updated.

FIG. 22 shows an example of displaying the mark according to S20005. FIG. 22 shows an overlay display of the broadcast cooperation application unit 173c1 and, in this example, the weather forecast, on the broadcast program screen 173c by executing the HTML document of the broadcast cooperation application. These are displayed by the processing of reading the HTML document (S2001) and the processing of executing (S20002).

Then, the broadcast receiving device 100 indicates that the HTML document of the broadcast cooperation application being executed is out of the range of the application boundary in the broadcast program screen 173c of FIG. 22 of the video display unit 173 by the process of S20005 of FIG. The mark 20200 is displayed. In this example, the mark 20200 marked with a cross in a circle is displayed by OSD or the like at the position of the lower right corner on the screen. By observing the display of the mark 20200, the user can know that the HTML document of the broadcasting cooperation application being executed is out of the application boundary.

The display is not limited to the above mark 20200 or an icon, an image, or the like, and a text message or the like may be displayed. An example of a message is "Outside the application boundary." Both the mark and the message may be displayed.

In the case of a broadcast cooperation application, the HTML document often displays information related to the broadcast video, and the content of the HTML document outside the application boundary may be less related to the broadcast video. Continuing to execute such an HTML document may not be beneficial to the user. Therefore, in the sixth embodiment, the state is notified to the user by the above mark and notified, and the transition from outside the application boundary to the HTML document in the application boundary is controlled.

In FIG. 21, in the sixth embodiment, after the mark display step S20005, a step S20006 for detecting whether or not the mark has been selected by the user is provided. In this step, it is detected that the user selects the mark 20200 by clicking with the cursor or the like on the screen of FIG. 22, or a predetermined user operation corresponding to the mark selection. At this time, a message or the like prompting a predetermined user operation may be displayed on the screen. Examples of messages are "Click to return to the application in the application boundary." "Press the XX button to return."

When the above mark is selected (S20006-Yes), the broadcast receiving device 100 is an HTML document that was executed before the HTML document that is currently being executed with respect to the broadcast cooperation application, and is in the current application boundary. Transition to the included HTML document (S20007). If the mark is not selected (S20006-No), the process returns to step S20003.

The transition process of S20007 is realized by, for example, an instruction to transition to a predetermined HTML document, in other words, information specified by the HTML document of the transition destination, or the like. The instruction of this transition or the like is described by, for example, AIT. In S20007, the transition is made according to the instruction of the transition, the main process is terminated, the main process is started again, and in step S20002, the HTML document of the transition destination is executed.

When there are a plurality of HTML document candidates for the transition destination in the process of S20007, for example, the HTML document for the transition destination is determined by the following method. In the first method, the HTML document executed last among the candidates is set as the transition destination. In the second method, among the candidates, the HTML document executed first, for example, the entry document is set as the transition destination.

Further, when the state outside the application boundary is changed in S20007 and the state is returned to the display state by executing another HTML document, a mark or a message indicating that may be displayed on the screen (S20009). An example of a message in that case is "Returned to the display of the application in the application boundary."

FIG. 23 shows an example of the operation such as the transition corresponding to the example of the broadcast cooperation application of FIG. 20 in the broadcast receiving device 100 of the sixth embodiment. The horizontal axis shows time. In the vertical direction, the broadcast wave AIT, application boundary, user operation, execution document, and display are shown in relation to each other.

At time t1, it is shown that the broadcast cooperation application, for example, App1 in FIG. 20 (a), is activated by the AIT of the broadcast wave. When the broadcast cooperation application is started, the entry document HTML1 is executed, and the screen is in the state of being displayed by HTML1. At this time, the application boundary 20101 of the broadcast cooperation application is HTML1 to HTML4.

At time t2, the document transition instruction 20221 was issued by a user operation. As a result, the transition from HTML1 to HTML2 is achieved, and the display state is set by HTML2. Further, at time t3, the transition instruction 20222 was issued by a user operation. As a result, the transition from HTML2 to HTML3 is achieved, and the display state is set by HTML3.

At time t4, it is shown that the application boundary is dynamically changed during the execution of the broadcast cooperation application, that is, during the broadcast of the broadcast program. That is, the application boundary 20101 has changed to the application boundary 2022. This change is described, for example, in AIT. The application boundary 2022 is covered by two documents, HTML1 and HTML2.

At t4, the document being executed is HTML3, which is not included in the scope of application boundary 2022. The broadcast receiving device 100 detects that the HTML3 is out of the range of the application boundary 2022 (S20004 above), and displays the mark 20200 on the screen from t4 (20230). This notifies the user that the running HTML3 is outside the scope of the current application boundary 2022.

At time t5, the above mark 20200 was selected (20223) by a user operation. As a result, the broadcast receiving device 100 stops displaying the mark 20200, and transitions to the HTML document executed before the HTML3 being executed at this time and the HTML document included in the current application boundary 2022. Here, since there are two documents (HTML1 and HTML2) as candidates for the transition destination corresponding to the condition, they are selected from them. For example, according to the first method, the last executed HTML document, that is, HTML2 is determined as the transition destination. As a result, it returns to the display state by executing HTML2. In this case, since the user will see the state by HTML2 that was seen immediately before, it is easy to recognize the situation.

When the second method is used, the mark selection (20223) determines HTML1, which is the first executed entry document, as the transition destination. As a result, it returns to the display state by executing HTML1. In this case, since the user revisits the state by HTML1 that was first seen at the time of startup, it is easy to recognize the situation.

At time t6, a user-operated end instruction (20224) of the broadcast cooperation application was given from the state of HTML2, and the broadcast cooperation application was terminated by this. Of course, the broadcast cooperation application may not be terminated here, and may be continuously used, such as transitioning to another HTML document.

In the above configuration, the selection of the mark by the user operation is adopted as a means for transitioning to the HTML document within the range and returning the display state when the application boundary is changed. The transition is not limited to this, and the transition may be made by a user operation of a predetermined button for which a function corresponding to the above means provided in the remote controller of the broadcast receiving device 100 is set.

In the above configuration, the case where one broadcast cooperation application is started has been described, but the case where a plurality of broadcast cooperation applications are started at the same time is also possible. When multiple broadcast cooperation apps are started at the same time, marks, messages, etc. on the screen are displayed near the display unit corresponding to the application that is out of the application boundary among the multiple broadcast cooperation apps, for example. ..

With the above configuration, the transition destination document at the time of control to return to the state in the application boundary may be specified by information such as AIT. Further, in the above configuration, the control method such as returning to the document of the immediately preceding execution or returning to the entry document as the transition destination, and the control method such as whether to make a transition based on the selection of the mark or automatically make a transition Is preset as a specification of the broadcast receiving device 100. Further, the control method may be specified by information such as AIT. In that case, the broadcast receiving device 100 refers to the information such as the AIT and recognizes the transition destination document and the control method. Further, regarding the above control method, the user may be able to set the selection of the broadcast receiving device 100.

In the above configuration, when a new HTML document is added within the range of the changed application boundary due to the dynamic change of the application boundary, the added document may be a candidate for the transition destination. FIG. 24 shows Application Boundary 20203, which is an example after such a change. In the application boundary 20203, HTML5, which is HTML document 20151, is added to HTML1 and HTML2. The broadcast receiving device 100 may set HTML5 as a transition destination, for example, when controlling to return from the state of HTML3, which is outside the range of the application boundary 20203. In this case, the user sees the display status of the new HTML5, and can easily recognize the status of the change in the application boundary.

As described above, according to the broadcast receiving device 100 of the sixth embodiment, by displaying the mark 20200 on the video display unit 173, the user can tell that the HTML document in which the broadcast cooperation application is being executed is out of the range of the application boundary. You can know. In addition, simple operations such as selecting the displayed mark and operating the buttons on the remote controller can return to the state of the HTML document within the range of the application boundary, which is convenient for the user.

As another embodiment, when the application boundary is out of the above application boundary, the transition from the HTML document being executed to another HTML document corresponding to the above conditions can be controlled immediately without displaying the mark. Good. That is, the user operation may be omitted and the state may be automatically returned to the state according to the previous HTML document. In the case of this embodiment, the control is a flow in which S20005 and S20006 are eliminated in FIG. In this case, the broadcast receiving device 100 may display a mark or a message indicating the control content, for example, "Since it is an application outside the boundary, the display has returned to the display of the application inside the boundary." (S20009). In the case of this embodiment, since mark selection and the like are not required, the user has less time and effort.

As another embodiment, information including a list of documents (for example, HTML1 and HTML2) that are candidates for the transition destination is displayed on the screen, a transition destination is selected by user operation from the list, and the selected document is used. It may be controlled to return to the display state. FIG. 25 shows a screen example of the display according to this embodiment. When it is out of the application boundary, information such as 20300 is displayed in a part of the screen. 20300 includes the message and the above list. An example message is "Outside the application boundary. Please select a return destination." The list displays HTML1 and HTML2, which are documents included in the range of the current application boundary 2022 of the broadcast cooperation application App1, as transition destination candidates, and accepts an operation of selecting a transition destination document by the user. The user can return to the desired display state by selecting a document from the list.
