[Overview of application control information (AIT)]
The application control information (AIT) of this embodiment is an application ( Hereafter, it may be referred to as a broadcast cooperation application.) and is information intended to instruct its control. In addition, the broadcast cooperation application is (1) a broadcast managed system that operates only in a broadcast reception state based on a control signal such as start/end contained in a broadcast signal, and is permitted to access broadcast resources based on the control signal. applications, (2) non-broadcast managed applications that are allowed to access broadcast resources based on means such as application authentication in an operation mode in which activation/termination, etc. are not controlled by broadcast signals, and (3) broadcast resources. It may be distinguished from other general applications for which access is not permitted.

AIT transmission methods include a method of transmitting AIT in section format or XML (eXtensible Markup Language) format by broadcasting waves using a data carousel (DC) method or the like, and a method of transmitting AIT files in section format or XML format over the Internet. 200 server device using http (Hypertext Transfer Protocol) or https (Hypertext Transfer Protocol Secure). Other methods may be adopted.

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

The application type 901 defines the application description method. In this embodiment, it is assumed that the description method of the application is HTML. The application identifier 902 is identification information composed of an organization identification for identifying a business and an application identification numbered for each business, for identifying an application unit. Note that an application unit is a set of HTML documents and their reference resources, each of which has an HTML document existing at a location specified by the application acquisition source information 905 as an entry document. The application control code 903 defines operation control for the target application, and describes one of (1) automatic activation, (2) operable, (3) termination, and (4) prefetch. . The application profile 904 is a value indicating the functions of the television receiver required by the application, and indicates a combination of functions that the television receiver has as options. Whether or not the application can be used is determined by referring to this value.

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

Activation priority 907 defines which of the data broadcast by the broadcast service and the broadcast managed application by the HTML document should be preferentially activated when they exist at the same time. unconditionally designating data broadcasting as top priority on the PMT, designating the startup priority of a specific application type on the PMT, and designating the startup priority of the target application with the startup priority 907; shall be possible. The cache information 908 is information used for cache control when holding application resources in preparation for reuse of the application. With this information, it is possible to cache application resources assuming reuse even after the application ends. 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 application control codes according to the setting of this parameter.

The operation of the broadcast receiving apparatus 100 of this embodiment will be described below.

[Operation sequence at application startup]
First, the process of activating the broadcast cooperation application based on the AIT transmitted by the broadcast wave in the broadcast receiving apparatus 100 of the present embodiment will be described. In the broadcast receiving apparatus 100 of the present embodiment, when the data broadcast by the broadcast service and the broadcast cooperation application exist at the same time, which one is prioritized 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 with

FIG. 7A is an operation sequence diagram showing an example of the operation sequence of the broadcast-linked application when it is specified that the broadcast-linked application should be preferentially activated. The figure shows a series of flows until the broadcast receiving apparatus 100 confirms the PMT and AIT as appropriate and activates a predetermined broadcast cooperation application.

When the tuner/demodulator 131 of the broadcast receiver 100 selects the channel desired by the user and acquires the TS, next, the main control unit 101 acquires the PMT data string separated by the first separator 132. (S101), the activation priority described in the PMT is confirmed. When it is confirmed in the process of S101 that the activation priority of the broadcast-linked application is high (S102), the application control unit 161 acquires the AIT data string separated by the first separation unit 132 (S103), and the acquired AIT The application control code 903 in the data string is confirmed (S104). In the process of S104, if the application control code 903 is "automatic start", furthermore, the application profile 904 of the acquired AIT data string is confirmed (S105), and execution of the broadcast cooperation application specified in the AIT is confirmed. When it is confirmed that it is possible, based on the information described in the application acquisition destination information 905, a transmission request for the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121. (S106).

Service provider server 400 that has received the transmission request of the broadcast cooperation application, based on the control of application management / distribution execution unit 4103, after performing authentication processing of broadcast receiving device 100 as necessary, in application storage area 4013 Distribution of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S107). Note that a known method may be used for the authentication process, and a detailed description thereof will be omitted. Next, under the control of the application control unit 161, 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. (S108).

FIG. 7B is an operation sequence diagram showing an example of the operation sequence of the broadcast cooperation application when it is specified that the data broadcast by the broadcast service should be preferentially activated. The figure shows a series of flows until the broadcast receiving apparatus 100 confirms the PMT and AIT as appropriate and activates a predetermined broadcast cooperation application.

When the tuner/demodulator 131 of the broadcast receiver 100 selects the channel desired by the user and acquires the TS, next, the main control unit 101 acquires the PMT data string separated by the first separator 132. (S201), the activation priority described in the PMT is confirmed. When it is confirmed in the process of S201 that the data broadcast by the broadcast service has a high activation priority (S202), the data broadcast reception processing unit 141 acquires the BML data string separated by the first separation unit 132 and converts it into a BML document. Play back (S203). When automatic activation of data broadcasting is set by the BML document, and when the user uses an operation terminal (portable information terminal 700, remote controller, etc.) to request activation of data broadcasting (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 process of S205 or simultaneously with the process 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). In the process of S207, when it is confirmed that the broadcast-linked application specified by the AIT can be executed, an entry button to the executable broadcast-linked application is displayed on the data broadcasting screen. The entry button may always be displayed, and the color scheme may be changed from the inactive color to the active color only when the broadcast cooperation application can be executed. By changing the shape, the entry button may be switched between an inactive state and an active state.

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

Service provider server 400 that has received the transmission request of the broadcast cooperation application, based on the control of application management / distribution execution unit 4103, after performing authentication processing of broadcast receiving device 100 as necessary, in application storage area 4013 Distribution of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S212). Next, under the control of the application control unit 161, 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. (S213).

FIG. 7C is an operation sequence diagram showing an example of the operation sequence of the broadcast cooperation application when no priority activation is specified. The figure shows a series of flows until the broadcast receiving apparatus 100 confirms the PMT and AIT as appropriate and activates a predetermined broadcast cooperation application.

When the tuner/demodulator 131 of the broadcast receiver 100 selects the channel desired by the user and acquires the TS, next, the main control unit 101 acquires the PMT data string separated by the first separator 132. (S301), the startup priority described in the PMT is confirmed. When it is confirmed in the process of S301 that the broadcast-linked application has a high activation priority (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 in the data string is confirmed (S304). In the process of S304, if the application control code 903 is "startable" instead of "automatic start", the display of the broadcast program is continued without starting neither the data broadcasting by the broadcasting service nor the broadcast cooperation application.

In the state after the processing of S304 is completed, when the user uses the operation terminal to request the activation of data broadcasting (S305), the acquisition of the BML data string and the processing of the BML Reproduction of documents, generation of data broadcasting screen information, etc. are performed (not shown). On the other hand, when the user uses the operation terminal to request activation of the broadcast-linked application launcher after the processing of S304 is finished (S306), the application control unit 161 separates the AIT data separated by the first separation unit 132. A string is obtained (S307), and the application profile 904 of the obtained AIT data string is confirmed (S308). Furthermore, the application control unit 161 displays a list of executable broadcast-linked applications as a broadcast-linked application launcher on the video display unit 173 (S309).

When the user selects a predetermined broadcast-linked application from the broadcast-linked application launcher displayed in S309 using the operation terminal (S310), the application control unit 161 separates the AIT data string separated by the first separation unit 132 into (S311), and confirms the application acquisition destination information 905 of the acquired AIT data string. Further, based on the information described in the application acquisition destination information 905 confirmed in S311, a transmission request for the broadcast cooperation application is transmitted to the predetermined service provider server 400 via the LAN communication unit 121 (S312).

Service provider server 400 that has received the transmission request of the broadcast cooperation application, based on the control of application management / distribution execution unit 4103, after performing authentication processing of broadcast receiving device 100 as necessary, in application storage area 4013 Distribution of the stored predetermined broadcast cooperation application is performed via the LAN communication unit 421 (S313). Next, under the control of the application control unit 161, 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. (S314).

In addition, in the activation sequence of the broadcast cooperation application described with reference to FIGS. 7A to 7C, an example of acquiring AIT from broadcast waves is described. Alternatively, the AIT file may be acquired from. Also, 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 AIT indicates a broadcast wave, the application control unit 161 transmits the HTML data string by the data carousel method or the like and is separated and output by the first separating unit 132. , and the application engine 162 executes the reproduced HTML document (broadcast-linked application).

It should be noted that if there is no information specifying the activation priority when the data broadcast by the broadcasting service and the broadcast cooperation application exist simultaneously on the PMT, the activation is performed only by information such as the application control code 903 and the activation priority 907 of the AIT. You may make it confirm a priority. Similarly, even if the acquisition of the information on the PMT fails, the activation priority may be confirmed only by information such as the application control code 903 of the AIT and the activation priority 907 . That is, regardless of the information on the PMT, the AIT is periodically checked, and if there is a broadcast-linked application specified by "automatic start" in the application control code 903 of the AIT, the broadcast-linked application Activation is prioritized, and if there is no broadcast-linked application designated by "automatic activation" in the application control code 903 of the AIT, activation of data broadcasting by the broadcasting service may be prioritized.

Further, when there is no response from the service provider server 400 for a predetermined period of time or more when the distribution request for the broadcast cooperation application is made in S106, S211, or S312, a message such as "Please wait for a while" is displayed on the video display unit 173. You may make it display. Alternatively, in this case, a message may be displayed asking the user to stop executing the broadcast cooperation application.

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

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

It is assumed that the cooperative control application is installed in the storage unit 710 of the mobile information terminal 700 in advance as the cooperative control program 7002 .

When the user instructs the activation of the cooperative control application on the portable information terminal 700 (S401), the cooperative control execution unit 7102 of the portable information terminal 700 searches for a television receiver capable of communication (cooperative operation) on the network ( S402), the search result is displayed on the display unit 741 as a television receiver list. If a communicable television receiver cannot be found, a message to that effect is displayed and the process ends. When the user selects an arbitrary television receiver (broadcast receiving device 100 of this embodiment) from the television receiver list, the cooperation control execution unit 7102 displays a login screen for connecting to the broadcast receiving device 100 on the display unit 741. do. When the user inputs authentication information (login name and password specified by the broadcast receiving apparatus 100, etc.) to the login screen via the operation unit 730 (S403), the cooperation control execution unit 7102 receives the input authentication information. is stored in the authentication information storage area 7012 and simultaneously transmitted to the broadcast receiving apparatus 100 (S404). The process of transmitting the authentication information to the broadcast receiving device 100 may be performed via the LAN communication unit 721 and the router device 210, or may be performed directly to the broadcast receiving device 100 via the NFC communication unit 723. .

FIG. 10 is a screen display diagram showing an example of an error display screen when it is determined that the application cannot be executed, when the description of the AIT is insufficient, or when acquisition of the AIT fails.

In the broadcast receiving apparatus 100 of the present embodiment, when it is determined that the broadcast cooperation application cannot be executed, the reason why the broadcast cooperation application cannot be executed, such as the confirmation result of the application profile 904, is It is displayed in the error message 173d1. For example, as a result of checking the application profile 904, if a predetermined optional function is lacking on the television receiver side, an error message 173d1 to that effect is displayed. It is also possible to display an error code and a guide (URL or the like) of the home page of the television receiver maker in which an explanation of the error code is described. Alternatively, when the broadcast-linked application is acquired from the network, the network connection status is of course confirmed in advance. If it is not possible, an error message 173d1 to that effect is displayed. Also, the error message 173d1 may be displayed when the broadcast cooperation application cannot be correctly acquired due to a bad error situation, even though the network connection is established. An error message 173d1 may be displayed when acquisition of a broadcast-linked application is being executed and the broadcast-linked application cannot be executed yet. In addition, the error message 173d1 is also displayed when the reception of the broadcast wave is unstable and the information such as AIT can be received at first, but the information such as AIT cannot be received halfway through. 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 condition of the broadcast wave is recovered.

Also, if the result of checking the application profile 904 is that the television receiver lacks a predetermined optional function, an error message 173d1 is displayed to the effect that confirmation or update of the latest firmware for the television receiver is recommended. You can do it. Alternatively, the confirmation or update of the latest firmware may be automatically performed by the broadcast receiving apparatus 100 . Alternatively, if the broadcast cooperation application can be executed by adding paid optional hardware or optional software to the television receiver, a guide for the paid optional hardware or optional software may be displayed. good. Note that the error message 173d1 may be displayed on the mobile information terminal 700 instead of the broadcast receiving device 100. FIG.

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 apparatus 100 and the mobile information terminal 700. FIG.

[EPG screen of broadcast receiving device]
FIG. 16A is a screen display diagram showing an example of an electronic program guide (EPG) display screen in the broadcast receiving apparatus 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. FIG. It is assumed that the EPG display screen 173e is displayed on the video display unit 173 by selecting the program guide key 741a7 on the basic screen 741a of the cooperative control application.

In this embodiment, the EPG display screen 173e is in a matrix form with the vertical axis representing time and the horizontal axis representing service IDs (channels). indicate. Detailed information 173e1 of each broadcast program is mainly composed of a title area 173e2 and a detailed description area 173e3, as shown in FIG. 16A.

The title area 173e2 displays the program title of each broadcast program, symbols representing attributes of each broadcast program, and the like. The symbols and the like representing the attributes of each broadcast program are, for example, a symbol that symbolizes "New" that means that it is a new program, a symbol that symbolizes "Replay" that means that it is a rebroadcast program, etc. Alternatively, a mark or the like that symbolizes "data", which means that data broadcasting by a broadcasting service is supported, may be used. Further, in the case of a broadcast program for which a broadcast cooperation application that can be executed by the broadcast receiving apparatus 100 of the present embodiment is prepared, a mark or the like that symbolizes "Linkage" to that effect may be used. The detailed explanation area 173e3 displays related information such as the contents of each broadcast program, the performers, the URL of the homepage introducing each broadcast program, and the like.

It should be noted that even if a broadcast cooperation application is prepared for the broadcast program, the mark or the like symbolizing the "Linkage" displayed in the title area 173e2 is displayed on the information display device as a result of checking the application profile 904. If execution by 100 is not possible, it may not be displayed. In addition, the mark symbolized by "Linkage", which is displayed in the title area 173e2 and indicates that the broadcast program is prepared with the executable broadcast-linked application, furthermore, the linked operation with the portable terminal device is possible. The color, shape, font, etc. may be changed depending on whether or not it is. If the linked operation with the portable terminal device is possible, the symbol symbolized "Mobile" may be displayed together with the symbol symbolized "Linkage".

The presence or absence of the mark symbolizing "Linkage" and the symbol symbolizing "Mobile" is indicated in advance in the EIT information including detailed information of each broadcast program. Whether or not the broadcast program has a broadcast cooperation application that can be executed by the broadcast receiving apparatus 100 of the embodiment, whether or not the executable broadcast cooperation application can perform cooperative operation with a mobile terminal device, It may be controlled by acquiring information such as. Alternatively, the information obtained from the program distribution information of the digital broadcast programs prepared in a predetermined server device on the Internet 200 is stored in an electronic program guide created based on the program information data string obtained from the broadcast waves of the digital broadcast service. You may make it add.

As described above, on the EPG display screen 173e, there is a symbolic mark of "Linkage" indicating that the broadcast program is prepared with an executable broadcast-linked application, and that linkage operation with a mobile terminal device is possible. By displaying a mark that symbolizes "Mobile" indicating , the user can easily grasp the correspondence status of each broadcast program in the broadcast receiving apparatus 100 to the broadcast-communication cooperation service. Needless to say, the marks obtained by symbolizing the predetermined characters representing the attributes of each broadcast program may be replaced with the characters themselves, sentences, 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 indicated. In addition, the symbolized mark of "Linkage" and the symbolized mark of "Mobile" are not usually displayed in the title area 173e2. It may be made to be displayed.

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

In the above-described process, if the broadcast program for which the viewing reservation and/or the recording reservation has been made is a broadcast program corresponding to the broadcast and communication cooperation service, the broadcasting is triggered by the viewing reservation and/or the recording reservation. 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 URL) designating the acquisition destination of the broadcast cooperation application is described in the EIT information including 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 at the time when the broadcast program is selected with the program selection cursor 173e4. Become. Therefore, the broadcast receiving apparatus 100 can start acquiring the broadcast cooperation application before the broadcast start time of the broadcast program.

In addition, if the broadcast program for which the viewing reservation and/or recording reservation has been made is a broadcast program compatible with the broadcast and communication cooperation service and is a broadcast program that can be operated in cooperation with the mobile terminal device, The broadcast cooperation application (terminal side) provided in the above may also start acquiring before the broadcast start time of the broadcast program by the same processing as described above. Also, as shown in FIG. 16B, a two-dimensional barcode 173e5 or the like indicating the information (location information such as URL) of the acquisition source of the broadcast cooperation application (terminal side) prepared for the mobile terminal device is displayed on the EPG display screen 173e. may be displayed to prompt the user to download the broadcast cooperation application (terminal side) prepared for the mobile terminal device.

In this way, if the broadcast receiving apparatus 100 refers to the acquisition destination information of the broadcast-linked application included in the EPG information and starts acquiring the broadcast-linked application before the broadcast start time of the broadcast program. , it becomes possible to distribute the load on the service provider server 400 that stores the broadcast cooperation application. Also, even if 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 broadcast program starts broadcasting. become.

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

While viewing a digital broadcast service, the main control unit 101 of the broadcast receiving device 100 acquires the program information data string output from the first separating unit 132 (S701). When the user uses the operating terminal to request activation of the EPG screen (S702), an EPG display screen 173e is displayed on the video display unit 173 (S703). When the user selects an arbitrary broadcast program using the operation terminal on the EPG display screen 173e to make a viewing reservation and/or 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 recording reservation has been made is confirmed (S706).

After the process of S706, the application control unit 161 transmits a transmission request for the broadcast cooperation application to the predetermined service provider server 400 via the LAN communication unit 121 based on the confirmed URL (S707). Service provider server 400 that has received the transmission request of the broadcast cooperation application, based on the control of application management / distribution execution unit 4103, after performing authentication processing of broadcast receiving device 100 as necessary, in application storage area 4013 Distribution of the stored predetermined broadcast cooperation application is performed 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, which is received via the LAN communication unit 121, in the RAM 104 or the storage 110 (S709).

According to the transmitting/receiving apparatus 100 of the present embodiment described above, it is possible to execute functions with higher added value.

A second embodiment of the present invention will be described below. It should be noted that the configuration and effects of this embodiment are the same as those of the first embodiment unless otherwise specified. Therefore, the differences between the present embodiment and the first embodiment will be mainly described below, and descriptions of common points will be omitted as much as possible to avoid duplication.

Although Embodiment 1 has also described an embodiment in which mobile information terminal cooperation processing (hereinafter referred to as terminal cooperation) is performed, a more detailed embodiment will be described.

When performing mobile information terminal cooperation, there are cases where it is desired to restrict the use of terminal cooperation to only mobile information terminal 700 in the same home as broadcast receiving apparatus 100 (this restriction is hereinafter referred to as same-home restriction). For example, in an application for using broadcast cooperation (hereinafter referred to as a broadcast cooperation application), when the display screen of the broadcast receiving device 100 and the display screen of the mobile information terminal 700 are closely related, or when the broadcast receiving device 100 This is the case, for example, when it is desired that the user of the mobile information terminal 700 certainly views the displayed advertisement video.

A point that must be considered as a procedure is a judgment as to whether or not the target broadcast-linked application imposes same-home restrictions. If it is assumed that all broadcast-linked applications are restricted within the same home, this determination is not necessary. will need to acquire and change operating procedures. The control information regarding the presence or absence of this restriction may be acquired from the broadcast signal (for example, described as an item of AIT) or may be acquired from a server designated by the broadcasting station.

In this embodiment, including the above procedure, the procedure for ensuring that the portable information terminal 700 and the broadcast receiving apparatus 100 are in the same home will be described.

Generally, devices existing in the same home exist on a local network connected to the same router device 210 . Therefore, it can be determined that the mobile information terminal 700 is connected to the same local network as the broadcast receiving apparatus 100, and that the mobile information terminal 700 exists in the same house. A well-known method may be used to determine whether or not the target device is connected to the local network, and a description thereof will be omitted.

Also, even if the portable information terminal 700 is not on the local network, it can be determined that it exists in the same home by directly communicating with the broadcast receiving apparatus 100 using NFC, BlueTooth, infrared communication, or the like. In this case, the communication for acquiring the broadcast-linked application or the like may be the above-described direct communication or mobile phone communication.

As described above, there are a plurality of possible methods for confirming the presence in the same home.

Furthermore, once it is confirmed that the portable information terminal 700 exists in the same home, it may be assumed that it exists in the same home until the end of the program. is assumed to exist in the same house, but if the valid time has passed, it is not assumed to exist in the same house unless a new confirmation is made. This valid time is described in AIT, for example, and read by the broadcast receiving apparatus 100 .

Furthermore, for example, an event signal may be set in the broadcast signal at an arbitrary point during program progress, and the presence of the portable information terminal 700 in the same home may be confirmed each time the event signal is received. can also

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

Next, a specific procedure for permitting terminal cooperation only to portable information terminals 700 existing in the same home will be described. In this embodiment, restrictions are set when the mobile information terminal 700 acquires a broadcast-linked application or acquires information used by the broadcast-linked application (hereinafter referred to as a broadcast-linked application and information used by the broadcast-linked application, specifically Typically, it is an HTML document, streaming video, etc., but they are collectively called broadcast link information). There are two methods for obtaining the broadcast linkage information: communication acquisition, which acquires from the broadcasting station server 300 or the provider server 400, and broadcast acquisition, which acquires from broadcast waves. In the case of communication acquisition, there are two methods: acquisition after the start of broadcast reception and acquisition before the start of broadcast reception. Furthermore, in the case of communication acquisition, when the broadcast receiving device 100 acquires once and the mobile information terminal 700 acquires from the broadcast receiving device 100, and when the mobile information terminal 700 acquires directly from the broadcast station server 300 or the operator server 400 There is There are various methods, but when viewed from the portable information terminal 700 , it can be roughly divided into two cases: acquisition from the broadcast receiving device 100 and acquisition from the broadcast station server 300 or the provider server 400 .

In this embodiment, a case where the mobile information terminal 700 acquires the broadcast cooperation information from the broadcast receiving apparatus 100 will be described, and a case where it is acquired from the server will be described in the next embodiment.

FIG. 18A shows the procedure of this example.

First, before performing terminal cooperation, a cooperation control application, which is an application for controlling terminal cooperation, is activated in each of the mobile information terminal 700 and the broadcast receiving apparatus 100 (S10001, S10002). In this state, the portable information terminal 700 makes a terminal cooperation request to the broadcast receiving apparatus 100 (S10003). Next, AIT is obtained from the broadcast signal (S10004). From this AIT information, it is determined whether or not the application for the target mobile information terminal has restrictions within the same home (S10006). Then, the process proceeds to step S10009, and it is determined whether or not the mobile information terminal 700 that requested terminal cooperation is in the same home as the broadcast receiver 100 (S10009). As a result of the determination, if it is determined that the device is not in the same home, a response of non-permission of cooperation is sent to the cooperation control application on the portable information terminal side, and the process ends (S10011).

Here, in the case of the premise that all broadcast cooperation applications have the same in-house restriction, the determination in S10006 is skipped without being performed. S10006 is determined when there are both applications with and without the same in-house restriction.

If it is determined that mobile information terminal 700 is in the same home, or if the application does not have same-home restrictions, the process advances to S10012 to perform broadcast-linked application-related services. 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). This broadcast cooperation information includes information received by the broadcast receiving apparatus 100 from a distribution server, which is the provider server 300 (S10014, S10015, S10016), information acquired from the broadcast signal (S10017), and information stored in the broadcast receiving apparatus 100. There are things that have been done. The reception of the broadcast cooperation information by the broadcast receiving device 100 (S10016, S10017) is not limited to the broadcast cooperation information delivery request (S10013) from the mobile information terminal 700, but the broadcast receiving device 100 autonomously obtains it, There may be cases where acquisition is based on occurrence of events from broadcast signals. Also, the distribution of the broadcast linkage information to the portable information terminal 700 (S10018) may be voluntarily performed by the broadcast receiving apparatus 100 side.

After a series of reception (acquisition) and distribution processing of the broadcast cooperation information is completed, it is determined whether or not the broadcast receiving apparatus 100 continues viewing the same program (S10019). A response of cooperation disapproval is sent to the cooperation control application, and the process ends (S10020).

If the viewing is continued, the procedure returns to S10005, and if there is an in-home restriction, it is checked whether the mobile information terminal 700 is in the same home (S10009). or whether there has been a confirmation request (S10007) from the broadcast signal or distribution server since the previous confirmation (S10008). Confirmation (S10009) is not performed, and execution of the next broadcast-linked application-related service (S10012) is performed via S10010. Here, it is described that the confirmation request (S10007) from the broadcast signal is obtained from the broadcast cooperation information, but here, the event message is also included in the broadcast cooperation information. Furthermore, this confirmation request may be written in the AIT.

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

Furthermore, the authentication information described in the AIT may be incorporated into the authentication key used for authentication in the distribution server (S10015). This makes it possible to confirm that the authentication request is legitimate. In addition, if the authentication information described in the AIT is changed as the program progresses, and if the delivery server does not perform authentication unless the authentication key incorporates information synchronized with the progress of the program, then the same program You can confirm that you continue to watch. In this case, the AIT information is appropriately read and updated (S10021). Note that the authentication information to be incorporated into the broadcast signal may be incorporated as broadcast cooperation information instead of 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-linked application-related service (S10012), the portable information terminal 700 receives the broadcast at each preset effective time, or at each broadcast signal or confirmation request from the distribution server. By confirming whether or not the device 100 is in the same home as the device 100, it is possible to appropriately execute broadcast-related applications with same-home restrictions. Furthermore, by using the authentication information embedded in the broadcast signal for authentication in the distribution server, it is possible to ensure the validity of the distribution request. You can also confirm that you are still watching.

According to the mobile information terminal linking technology according to the present embodiment described above, it is possible to implement the same home restriction for the mobile information terminal linked with the broadcast receiving apparatus.

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

FIG. 18B shows the procedure of this example.

First, before performing terminal cooperation, a cooperation control application, which is an application for controlling terminal cooperation, is activated in each of the mobile information terminal 700 and the broadcast receiving apparatus 100 (S10101, S10102). In this state, the mobile information terminal 700 makes a terminal cooperation request to the broadcast receiving apparatus 100 (S10103). Next, AIT is obtained from the broadcast signal (S10104). Information such as the URL of the distribution server is obtained from this AIT information, and the information is transmitted to the portable information terminal 700 (S10105). Next, the broadcast receiving apparatus 100 issues a time confirmation request to the distribution server (S10106), and based on this request, the distribution server transmits time information to the broadcast receiving apparatus 100 (S10107). As a result, the subsequent authentication key issuance (S10115) can be performed according to the time of the distribution server.

Thereafter, loop control indicated by an arrow in S10127 is entered.

First, portable information terminal 700 issues an authentication key issuance request or a broadcast cooperation information distribution request to broadcast receiving apparatus 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 the broadcast signal, and corresponds to the procedure of S10126 in the latter stage.

In any case, when the request of S10109 is issued from the portable information terminal, it is determined whether or not the broadcast collaboration application has restrictions within the same home (S10111). Skip to S10114. If all the broadcast cooperation applications have the same in-home restriction, the determination in S10111 is not performed, and the process proceeds to S10112. In S10112, it is determined whether or not the portable information terminal that has issued the request is in the same home, and if not, terminal cooperation is terminated (S10113). If it is 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. The procedure of S10126 is also described because acquisition from the broadcast signal may be performed in addition to the acquisition from the distribution server.

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

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

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

The valid time may be the same in one program, or may be changed according to the progress of the program. Also, if there is no valid time setting, once authentication is performed, the authentication may be valid while the program is being viewed.

Furthermore, the authentication information described in the AIT may be incorporated into the authentication key used for authentication on the distribution server (S10117). This makes it possible to confirm that the authentication request is valid. In addition, if the authentication information described in the AIT is changed as the program progresses, and if the delivery server does not perform authentication unless the authentication key incorporates information synchronized with the progress of the program, then the same program You can confirm that you continue to watch. In this case, the AIT information is appropriately read and updated (S10124). Note that the authentication information to be incorporated into the broadcast signal may be incorporated as broadcast cooperation information instead of 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 case, the URL is changed when the distribution server is the same but the entrance is different. In this case, the procedures of transmitting distribution server information (S10105), requesting time confirmation (S10106), and transmitting time information (S10107) are performed each time the change is made.

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

In this case, after confirming that mobile information terminal 700 is in the same home, broadcast receiving apparatus 100 acquires broadcast cooperation information from the broadcast signal (S10119), and then distributes the information to mobile information terminal 700. (S10120).

When the broadcast cooperation information is changed as the program progresses, a change notification may be issued from the broadcast signal (S10110), and the broadcast cooperation information may be acquired with the notification as a trigger. In this case, if it is acquired from the distribution server, the broadcast receiving apparatus 100 issues an authentication key to the portable information terminal (S10115) and notifies that there has been a change notification. If it is within the validity period, the issuance of the authentication key may be omitted and only the change notification may be sent. In the case of acquisition from a broadcast signal, the broadcast receiving apparatus 100 acquires information (S10119) and distributes it to the mobile information terminal (S10120). In addition, in the case of acquisition from a broadcast signal, it may be confirmed that the mobile information terminal 700 is in the same home for each change notification. I don't mind. Here, it is described that the notification of change from the broadcast signal (S10110) is obtained from the broadcast linkage information, but here it is described that the event message is also included in the broadcast linkage information. Furthermore, this change notification may be written in the AIT.

After a series of reception (acquisition) and distribution processing of the broadcast cooperation information is completed, it is determined whether or not the broadcast receiving apparatus 100 continues viewing the same program (S10121). A response of cooperation disapproval is sent to the cooperation control application, and the process ends (S10123). If viewing is continued, the process returns to S10108 to continue loop processing S10127.

In this way, by including the time information in the authentication key used for authentication of the distribution server and managing the validity period, it is possible to periodically confirm that the portable information terminal 700 is in the same home as the broadcast receiving apparatus 100. It is possible to appropriately execute the broadcast cooperation application with the same in-house restriction. Furthermore, by using the authentication information embedded in the broadcast signal for authentication in the distribution server, it is possible to ensure the validity of the distribution request. You can also confirm that you are still watching.

According to the mobile information terminal cooperation technology according to the present embodiment described above, even when the mobile information terminal that cooperates with the broadcast receiving apparatus acquires the broadcast cooperation information from the distribution server, it is possible to realize the same home restriction. .

In Embodiments 2 and 3, the procedure for realizing the intra-house restriction in terminal cooperation has been described, but depending on the broadcast cooperation application, use from outside the home may also be permitted. This embodiment will explain such a case. For example, when a program such as television shopping is publicity/advertisement, it is desirable for broadcasters to be able to use the broadcast cooperation application regardless of whether it is inside or outside the home. In the case of such a program, once registered in the broadcast receiving apparatus 100, use of the broadcast cooperation application may be permitted regardless of whether the mobile information terminal 700 is at home. In this case, if there is a broadcast cooperation application that converts the broadcast video itself into streaming data and distributes it from the broadcast receiving device 100 to the mobile information terminal 700 via the Internet, the convenience will be further enhanced. Streaming data may be encrypted in broadcast receiving apparatus 100 for copyright protection. Whether or not the broadcast cooperation application permits use from outside the home, including distribution of broadcast video outside the home, is described in data (for example, AIT) in the broadcast signal.

A specific procedure is shown in FIG. 18C. Since a part of the procedure is common to the second and third embodiments, the description of the parts overlapping with the second and third embodiments will be omitted. When there is a terminal cooperation request (S10203) from outside the home, if the application is permitted to be used outside the home, the broadcast receiving device 100 confirms whether the request source is a registered portable information terminal ( S10205) allows cooperation. If necessary, personal digital assistant 700 and broadcast receiver 100 may be authenticated for copyright protection of broadcast video and broadcast link information (S10207). At that time, the authentication may be authentication in the distribution server (S10207). Information on whether or not copyright protection is required and information on the authentication method for copyright protection are acquired from the broadcast signal (for example, described in AIT), and control is performed accordingly. If such information is not stored in the broadcast signal, a predetermined method predetermined in broadcast receiving apparatus 100 is followed. For example, predetermined copyright protection processing may be performed. Further, it may be determined in advance that the broadcast receiving apparatus 100 does not perform copyright protection processing when such information is not stored in the broadcast signal.

A specific example of authentication for copyright protection is shown below. Only one of each of the following authentications may be performed. Alternatively, a plurality of authentications exemplified below may be combined. Also, the authentication illustrated below may be combined with other authentication processing not illustrated below.

[Authentication by ID and password]
When the mobile information terminal 700 is registered with the broadcast receiving apparatus 100, an ID and password are issued, and the broadcast receiving apparatus 100 confirms the ID and password and permits cooperation.

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

[Use of distribution server]
A method in which a distribution server issues an encryption key for decrypting encrypted video data. Portable information terminal 700 transmits the ID and password to the distribution server and acquires the 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 by transmitting this location information from the broadcast receiving device 100 to the mobile information terminal 700, More safety. If the mobile information terminal 700 cannot obtain the encryption key, it cannot decrypt the video or the like. Authentication may be completed by notifying broadcast receiving apparatus 100 from 700 that the encryption key has been obtained. Note that billing may be performed by the distribution server.

[Mutual Authentication of Encryption Key]
The encryption keys possessed by the broadcast receiving apparatus 100 and the portable information terminal 700 are mutually authenticated, and copyright protection is authenticated by obtaining confirmation.

When information stored in a broadcast signal indicates that copyright protection is required by a prescribed method, terminal cooperation is not permitted if copyright protection cannot be authenticated by the prescribed method. Moreover, even if there is no designation in the broadcast signal and authentication is performed by the default method of the broadcast receiving apparatus 100, terminal cooperation is not permitted if copyright protection cannot be authenticated by the default method.

When terminal cooperation is permitted, it is not confirmed whether or not the mobile information terminal 700 exists in the same house thereafter, and the request from the mobile information terminal 700 (S10211), the autonomous control of the broadcast receiving apparatus 100, the broadcast signal In accordance with the request (S10210) from (S10210), broadcast cooperation information is distributed to the mobile information terminal 700 (S10217), and an authentication key for the distribution server is issued (S10212). In this case, it is not necessary to perform control in which the valid time is set. Portable information terminal 700 outside the home acquires the broadcast cooperation information from broadcast receiving apparatus 100 or the distribution server using the issued authentication key (S10215). Also, the authentication information obtained from the broadcast signal (for example, described in the AIT) is embedded in the authentication key issued by the broadcast receiving apparatus 100, and the distribution server uses the authentication key in which the authentication information obtained from the broadcast signal is embedded. If access is permitted if there is, it is possible to further optimize the use outside the home.

Furthermore, there are cases where it is better not to allow unlimited use of broadcast-linked apps, such as when discounting premiums for watching programs. After that, it is preferable to permit the use of the distribution server even if it is not in the same house. In this case, mobile information terminal 700 does not have to be registered with broadcast receiving apparatus 100 .

A specific procedure in this case is shown in FIG. 18D. Since this procedure is partly the same as that of FIG. 18C, the explanation of the overlapping parts is omitted. First, in a state where mobile information terminal 700 is in the same home as broadcast receiving apparatus 100, mobile information terminal 700 issues a terminal cooperation request to broadcast receiving apparatus 100. (S10305) and permits cooperation. If necessary, personal digital assistant 700 and broadcast receiver 100 may be authenticated for copyright protection of broadcast video and broadcast link information (S10307). At that time, the authentication may be performed by an external distribution server. Information on whether or not copyright protection is required and information on the authentication method for copyright protection are acquired from the broadcast signal (for example, described in AIT), and control is performed accordingly. If such information is not stored in the broadcast signal, a predetermined method predetermined in broadcast receiving apparatus 100 is followed. For example, predetermined copyright protection processing may be performed. Further, it may be determined in advance that the broadcast receiving apparatus 100 does not perform copyright protection processing when such information is not stored in the broadcast signal.

A specific example of authentication for copyright protection is shown below. Only one of each of the following authentications may be performed. Alternatively, a plurality of authentications exemplified below may be combined. Also, the authentication illustrated below may be combined with other authentication processing not illustrated below.

[Use encryption key]
While portable information terminal 700 is in the same home, broadcast receiving apparatus 100 transmits an encryption key for decrypting encrypted video data and the like to the portable information terminal. This encryption key may be acquired from a broadcast signal (for example, described in AIT). Authentication is achieved by handing over this encryption key within the same home. Furthermore, if the encryption key cannot be obtained from the broadcast signal until a certain point in the program, and the transfer of the encryption key to the portable information terminal 700 is limited to within the same home, the user must be in the same home at that time. Limits can be set and can be used to award premiums for viewing.

[Use of distribution server]
A method in which a distribution server issues an encryption key for decrypting encrypted video data. Portable information terminal 700 transmits the ID and password to the distribution server and acquires the 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 by transmitting this location information from the broadcast receiving device 100 to the mobile information terminal 700, More safety. If the mobile information terminal 700 cannot obtain the encryption key, it cannot decrypt the video or the like. Authentication may be completed by notifying broadcast receiving apparatus 100 from 700 that the encryption key has been obtained. 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 a certain point in the program. If the delivery of the content is limited to within the same home, it is possible to set a restriction that the user must be in the same home at that time, which can be used to give a premium to viewing. Note that billing may be performed by the distribution server.

[Mutual Authentication of Encryption Key]
The encryption keys possessed by the broadcast receiving apparatus 100 and the portable information terminal 700 are mutually authenticated, and copyright protection is authenticated by obtaining confirmation. This authentication may be performed inside the house or outside the house.

When information stored in a broadcast signal indicates that copyright protection is required by a prescribed method, terminal cooperation is not permitted if copyright protection cannot be authenticated by the prescribed method. Moreover, even if there is no designation in the broadcast signal and authentication is performed by the default method of the broadcast receiver 100, terminal cooperation is not permitted if copyright protection cannot be authenticated by the default method. The procedure after terminal cooperation is permitted is the same as the procedure in FIG. 18C, so the explanation is omitted.

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

In an actual usage situation, it is more desirable to easily know whether or not there is a terminal-linked application for each program and which terminal-linked application can be used. In this embodiment, a method for displaying the availability of terminal-linked applications will be described. A terminal cooperation application refers to a broadcast cooperation application used in terminal cooperation.

FIG. 19A is an example of the launcher screen (173b11) of the broadcast cooperation application when there is a terminal cooperation application. The broadcast-linked application is displayed as a framed character icon. Broadcast cooperation applications (173b12 to 173b14) for the broadcast receiving apparatus 100 and broadcast cooperation applications (173b15 to 173b17) for the portable information terminal, which are associated with the program being viewed, are displayed. In this example, the application status is indicated by the thickness of the border surrounding the character string and the color of the border. Main body applications A, B (173b12, 173b13) and terminal applications A, B (173b15, 173b16) are available, and main body application C (173b14) and terminal application C (173b17) are unavailable. . A state in which the terminal application cannot be used means that none of the mobile information terminals 700 that are in a state of being able to communicate with the broadcast receiving apparatus 100 have the function to execute the application.

FIG. 19B is a screen after terminal application A is selected in FIG. 19A. The state of each mobile information terminal 700 related to terminal application A is shown. The portable information terminals displayed on this screen are terminals that have been linked with or registered with the broadcast receiving apparatus 100 in the past.

Mobile terminal 1 (173b22) and mobile terminal 2 (173b23) whose icons have a solid line frame are in a state capable of communicating with the broadcast receiving apparatus 100, and mobile terminal 3 (173b24) whose icon frame has a dotted line. and mobile terminal 4 (173b25) are not in a state where communication with broadcast receiving apparatus 100 is possible. Mobile terminal 1 (173b22) and mobile terminal 3 (173b24) whose icon frames are white have the function of executing terminal application A, and mobile terminal 2 (173b23) and mobile terminal 4 whose icon frames are gray. (173b25) indicates that the terminal application A does not have the function to execute. Furthermore, if the app is already running on the device, you may use an icon with a design that indicates that.

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

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

In FIG. 19C, when the application cannot be used, a mark (in this case, a circle with diagonal lines) is displayed superimposed on the image of the device to indicate that the application is not available. Also, regarding the broadcast receiving apparatus 100, if the application is already running, a mark indicating that fact (in this case, a circle with a dot) may be superimposed and displayed. With this display, it is possible to prevent the unnecessary operation of advancing the launcher procedure even though it has already been executed. In the case of the portable information terminal 700, it is also possible to display a mark indicating that the application is being executed when the application is being executed on all terminals that are capable of communicating with the broadcast receiver and that can execute the application.

FIG. 19D is the screen (173b41) after selecting application C (173b34) in FIG. 19C. The state of the portable 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 function of executing the broadcast-linked application, if it is not in a state capable of communicating with the broadcast receiving device 100, or if the broadcast-linked application is already being executed, it is displayed. A mark representing the object is superimposed on the icon. In this example, a circle is marked with a slash (173b44, 173b46) if it does not have an execution function, a triangle is marked with an exclamation mark (173b45, 173b46) if communication is not possible, and a circle is marked 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 having to activate the launcher each time. For example, when the power is turned on, when the channel is changed, when the broadcast cooperation application is changed at the beginning of the program or during the program, there is a change in the communication state between the broadcast receiving device 100 and the portable information terminal 700. In this case, when the execution status of the application changes, the icon is displayed only for a predetermined time, and the status at that time is displayed.

FIG. 19E shows an example of such a case. When an icon indicating the type of each device is displayed, it indicates that there is a broadcast cooperation application corresponding to that type of device. In this case, a circle with a slash indicates that there are no devices of that type that are enabled to run the app. A dot in a circle indicates that the app is running on all enabled devices of that type.

FIG. 19F is a display screen (10401) on the portable information terminal 700. FIG. When requesting terminal cooperation from the portable information terminal 700, it is more convenient to use a list that shows which broadcast cooperation application can be used in which broadcast receiving device 100. FIG. FIG. 19F shows an example of the list (10402). This table shows which broadcast receiver 100 at home can use the broadcast cooperation application corresponding to the program to be checked. In addition, if the status of each broadcast receiving device 100 is also displayed, the convenience will be enhanced especially when the device is used from outside the home. This example shows display examples such as the program being received, another program being received, empty, and another program reserved (when recording of another program is reserved from the middle of the program). Here, if a plurality of tuners exist in the broadcast receiving apparatus 100, displaying the status for each of the plurality of tuners will further enhance convenience. In Table 10202, branch numbers indicate 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. FIG. In the case of terminal cooperation, if broadcast video and audio can be distributed as streaming data, there is no need to use the video unit of the broadcast receiving device 100, and if the tuner in the broadcast receiving device 100 can be used, broadcasting 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 indicating whether the application corresponds to the broadcast receiving apparatus 100 or what type of portable information terminal 700 the application corresponds to is required for each broadcast-linked application. must be Also, broadcast receiving apparatus 100 and mobile information terminal 700 require information for executing corresponding applications. These pieces of information can be obtained by the broadcast receiving apparatus 100 by describing them in the AIT, for example.

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

A broadcast receiving apparatus 100 according to a sixth embodiment of the present invention will be described below. It should be noted that the configuration and effects of this embodiment are the same as those of Embodiments 1 to 5 unless otherwise specified. Therefore, in the following, differences between this embodiment and Embodiments 1 to 5 will be mainly described, and descriptions of common points will be omitted as much as possible to avoid duplication.

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

FIG. 20 shows the concept of transition of a broadcast cooperation application and an HTML document. (a) of FIG. 20 shows an example of transition between documents within the application boundary 20201 of the broadcast cooperation application 20110 and the application boundary 20201 .

In (a) of FIG. 20, from the state (20000) in which the broadcast receiving apparatus 100 is receiving the image by the broadcast signal as described above, or in which the BML document is executed and the data broadcasting screen information is displayed, App1, which is the broadcast cooperation application 20110, is activated. Activation of the broadcast cooperation application 20110 is based on automatic activation by AIT or user's instruction. When the broadcast cooperation application 20110 is started, HTML1 which is the first HTML document 20111 which is the entry document is executed.

App1, which is the broadcast cooperation application 20110, is composed of HTML1 to HTML4, which are four HTML documents 20111 to 20114 shown in the figure. In (a), four HTML documents 20111 to 20114 form an application boundary 20201 of a broadcast cooperation application 20110. In FIG. An application boundary indicates a boundary of areas where transition is possible, and is set in the AIT as a collection of one or more areas. A region here is an HTML document.

Each HTML document is provided with a link to another HTML document, and the link enables transition between HTML documents. Solid arrows indicate transition links. A dashed arrow indicates an example of transition execution. In the example of (a), bi-directional transition is possible between all HTML documents. Without being 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 application boundary may change during application execution. Therefore, an HTML document that was within the application boundary at the start of execution may fall outside the application boundary due to a change in the application boundary during execution.

(b) of FIG. 20 shows an example of an application boundary 20202 after the application boundary is changed from the state of (a) and a transition related to the application boundary 20202 . The changed application boundary 20202 is composed of two documents, an HTML document 20111 and an HTML document 20112 . In the application boundary 20202, mutual transition is possible by a bidirectional link between two documents.

For example, during the execution of the HTML document 20113 in (a) of FIG. 20, the application boundary 20201 is dynamically changed to the application boundary 20202 in (b). In this case, the HTML document 20113 is out of the application boundary 20202 .

As an example of the dynamic change of the application boundary, a broadcast station changes the information of the content of the AIT of the broadcast signal so as to change the application boundary according to the content of the broadcast.

Since the user does not intend to change the application boundary as described above, the user does not know the timing of the change and the state of the application boundary after the change. Therefore, the broadcast receiving apparatus 100 of Example 6 has a function of controlling operations as follows.

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

When executing the HTML document of the broadcast cooperation application, broadcast receiving apparatus 100 first reads the HTML document (S20001), 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 the first to fifth embodiments described above.

From step S20002 onward, the features of the operation of the broadcast receiving apparatus 100 of the sixth embodiment are shown. After S20002, the broadcast receiving apparatus 100 according to the sixth embodiment performs processing for confirming the presence or absence of interrupt processing (S20003). The interrupt processing here includes termination of a broadcast-linked application, transition to another HTML document within the application boundary, execution of another broadcast-linked application, and the like. If there is an interrupt process (S20003-Yes), the broadcast receiving apparatus 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 is omitted.

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

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

Note that the process of S20004 may be performed periodically, for example, once every few seconds, or may be performed when the HTML document is updated.

FIG. 22 shows an example of mark display in S20005 above. FIG. 22 shows an overlay display of the broadcast cooperation application section 173c1, weather forecast in this example, on the broadcast program screen 173c by executing the HTML document of the broadcast cooperation application. These are displayed by the HTML document reading process (S20001) and execution process (S20002).

21, the broadcast receiving apparatus 100 causes the broadcast program screen 173c of FIG. Mark 20200 is displayed. In this example, a circle mark 20200 with an X mark is displayed on the OSD or the like at the lower right corner of the screen. By viewing the display of the mark 20200, the user can know that the HTML document of the broadcast-linked application being executed is out of the application boundary.

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

In the case of a broadcast-linked application, the HTML document often displays information related to the broadcast video, and the contents of the HTML document outside the application boundary may have less relevance to the broadcast video. Continued execution of such HTML documents may not be beneficial to the user. Therefore, in the sixth embodiment, the mark is used to notify the user of the state, and control is performed to transition from outside the application boundary to the HTML document within the application boundary.

In FIG. 21, in the sixth embodiment, step S20006 for detecting whether the mark is selected by the user is provided after step S20005 for displaying the mark. In this step, it is detected that the user has selected a mark 20200 by clicking with a 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. An example of the message is "Click to return to the application within the application boundary."

When the above mark is selected (S20006-Yes), broadcast receiving apparatus 100 determines that the HTML document executed earlier than the currently executed HTML document regarding the broadcast cooperation application and within the current application boundary Transition to the contained HTML document (S20007). If no mark is selected (S20006-No), the process returns to step S20003.

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

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

In addition, when the transition from the state outside the application boundary in S20007 returns to the display state by executing another HTML document, a mark, message, or the like indicating this may be displayed on the screen (S20009). An example of the message in that case is "Returned to the display of the application within the application boundary."

FIG. 23 shows an example of operations such as the transition described above, corresponding to the example of the broadcast cooperation application in FIG. The horizontal axis indicates time. In the vertical direction, broadcast wave AIT, application boundaries, user operations, executable documents, and displays are shown in relation to each other.

At time t1, it shows that a broadcast cooperation application, for example, App1 in (a) of FIG. 20, was 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 displayed according to HTML1. At this time, the application boundary 20201 of the broadcast cooperation application is HTML1 to HTML4.

At time t2, a document transition instruction 20221 was performed by a user operation. As a result, a transition is made from HTML1 to HTML2, and the state of display by HTML2 is entered. Also, at time t3, a transition instruction 20222 is performed by a user operation. As a result, a transition is made from HTML2 to HTML3, and the state of display by HTML3 is entered.

At time t4, it indicates that the application boundary was dynamically changed during execution of the broadcast cooperation application, that is, during broadcasting of the broadcast program. That is, the application boundary 20201 is changed to the application boundary 20202 . This change is described in AIT, for example. The application boundary 20202 is defined by two documents, HTML1 and HTML2.

At time t4, the document being executed is HTML3 and HTML3 is not included within the application boundary 20202 . Broadcast receiving apparatus 100 detects that HTML3 is out of application boundary 20202 (S20004 above), and displays mark 20200 on the screen from t4 (20230). This notifies the user that the HTML3 being executed is out of the current application boundary 20202 .

At time t5, the mark 20200 was selected (20223) by user operation. As a result, the broadcast receiving apparatus 100 stops displaying the mark 20200 and transitions to the HTML document executed earlier than HTML3 being executed at this time and included in the current application boundary 20202 . Here, since there are two documents (HTML1 and HTML2) as transition destination candidates that satisfy the conditions, one of them is selected. For example, according to the first method, the last executed HTML document, that is, HTML2, is determined as the transition destination. As a result, the state returns to the state of displaying by executing HTML2. In this case, the user will be able to see again the HTML2 state that was viewed immediately before, so that the user can easily recognize the situation.

When the second method is used, mark selection (20223) determines HTML1, which is the entry document executed first, as the transition destination. As a result, the state returns to the state of display by execution of HTML1. In this case, the user will see again the HTML1 state that was first seen at the time of activation, so that the user can easily recognize the situation.

At time t6, an end instruction (20224) for the broadcast-linked application is issued by user operation from the state of HTML2, thereby terminating the broadcast-linked application. Of course, the application may continue to be used, such as transitioning to another HTML document, without terminating the broadcast cooperation application.

In the above configuration, selection of a mark by a user operation is adopted as a means of returning the display state by transitioning to the HTML document within the range when the application boundary is changed. Without being limited to this, for example, the above-described transition may be performed by user operation of a predetermined button provided on the remote control of the broadcast receiving apparatus 100 and having a function corresponding to the above-described means set.

In the above configuration, the case where one broadcast-linked application is activated has been described, but the same is possible when a plurality of broadcast-linked applications are activated at the same time. When multiple broadcast-linked applications are launched simultaneously, the marks, messages, etc. on the screen are displayed, for example, in the vicinity of the display unit corresponding to the application outside the application boundary among the multiple broadcast-linked applications. .

In the above configuration, the transition destination document upon control to return to the state within the application boundary may be specified by information such as AIT. Also, in the above configuration, regarding the control method such as whether to return to the immediately executed document or the entry document as the transition destination, and the control method such as whether to transition based on the selection of the mark or to automatically transition. are set in advance as specifications of the broadcast receiving apparatus 100 . Further, the above control method may be designated by information such as AIT. In this case, the broadcast receiving apparatus 100 refers to information such as the AIT and recognizes the transition destination document and control method. Further, the above control method may be set to be selected by the user for the broadcast receiving apparatus 100 .

In the above configuration, if a new HTML document is added within the changed application boundary due to the dynamic change of the application boundary, the added document may be the transition destination candidate. FIG. 24 shows an example application boundary 20203 after such changes. The application boundary 20203 has HTML5 as the HTML document 20115 added to HTML1 and HTML2. The broadcast receiving apparatus 100 may set HTML5 as a transition destination when performing control to return from the state of HTML3, which is outside the range of the application boundary 20203, for example. In this case, the user will be able to see the state of the new HTML5 display, and will easily recognize the change in the application boundary.

As described above, according to the broadcast receiving apparatus 100 of the sixth embodiment, by displaying the mark 20200 on the video display unit 173, the user is notified that the HTML document being executed by the broadcast cooperation application is out of the application boundary. can know In addition, by a simple operation such as selecting a displayed mark or operating a button on a remote controller, the user can return to the HTML document state within the application boundary, which is convenient for the user.

As another example, when the document is out of the application boundary, the HTML document being executed may be immediately transitioned to another HTML document that satisfies the above conditions without displaying the mark. good. In other words, the state of the previous HTML document may be automatically restored by omitting the user's operation. In the case of this embodiment, the control is the flow without S20005 and S20006 in FIG. In this case, the broadcast receiving apparatus 100 may display a mark or a message representing the content of the control on the screen, for example, "Because the application is outside the boundary, the display has returned to the application within the boundary." (S20009). In the case of this embodiment, since mark selection or the like is not required, the user is less troublesome.

As another example, information including a list of documents (for example, HTML1, HTML2) that are candidates for the transition destination is displayed on the screen, a transition destination is selected from the list by user operation, and the selected document is displayed. It may be controlled to return to the display state. FIG. 25 shows an example of a display screen according to this embodiment. When the application boundary is exceeded, information such as 20300 is displayed in part of the screen. 20300 contains the message and the list above.
