The detailed explanation area 173e3 displays related information such as the program contents and performers of each broadcast program, the URL of the homepage introducing each broadcast program, and the like.

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

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

As described above, on the EPG display screen 173e, a mark symbolizing "Linkage" indicating that the program is a broadcast program for which an executable broadcast cooperation application is prepared, and cooperation operation with a mobile terminal device are possible. By displaying the mark symbolizing "Mobile" indicating "Mobile", the user can easily grasp the correspondence status of each broadcast program in the broadcast receiving device 100 to the broadcast communication cooperation service. Needless to say, the mark in which a predetermined character representing the attribute of each broadcast program is symbolized may be replaced with the character itself, a sentence, or the like. By changing the background color of the detailed information 173e1 of each broadcast program, the correspondence status of each broadcast program to the broadcast communication cooperation service may be shown. In addition, the mark symbolizing the above "Linkage" and "Mobile"
Normally, the mark or the like symbolized with "e" is not displayed in the title area 173e2, and may be displayed in a pop-up only when each broadcast program is selected by the program selection cursor 173e4.

The broadcast receiving device 100 of this embodiment has a function of making a viewing reservation and / or a recording reservation for each broadcast program from the EPG display screen 173e. For example, while the EPG display screen 173e is displayed, use the cursor key 741ac on the basic screen 741a of the cooperation control application to E.
Move the program selection cursor 173e4 on the PG display screen 173e, and enter key 741ad.
By selecting an arbitrary broadcast program, a viewing reservation and / or a recording reservation of the selected broadcast program is made.

In the above-mentioned processing, when the broadcast program for which the viewing reservation and / or the recording reservation is made is a broadcast program corresponding to the broadcast communication cooperation service, the broadcasting is triggered by the viewing reservation and / or the recording reservation. The acquisition of the broadcast cooperation application prepared for the broadcast program may be started without waiting for the broadcast start time of the program. That is, information (location information such as a URL) for designating the acquisition destination of the broadcast cooperation application is described in the EIT information including the detailed information of each broadcast program. By doing so, the broadcast receiving device 100 can grasp the information of the acquisition destination of the broadcast cooperation application prepared for each broadcast program when the broadcast program is selected by the program selection cursor 173e4. Become. Therefore, the broadcast receiving device 100 can start the acquisition of the broadcast cooperation application before the broadcast start time of the broadcast program is reached.

If the broadcast program for which viewing reservation and / or recording reservation has been made is a broadcast program corresponding to the broadcast communication cooperation service and can be operated in cooperation with the mobile terminal device, it is for the mobile terminal device. The broadcast cooperation application (terminal side) prepared in the above may also be started to be acquired before the broadcast start time of the broadcast program by the same processing as described above. Further, as shown in FIG. 16B, information on the acquisition destination of the broadcast cooperation application (terminal side) prepared for the mobile terminal device (terminal side).

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

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

While viewing the digital broadcasting service, the main control unit 101 of the broadcast receiving device 100 acquires the program information data string output from the first separation unit 132 (S701). When the user makes a request to start the EPG screen using the operation terminal (S702), the EPG display screen 1 is displayed on the video display unit 173.
73e is displayed (S703). When the user selects an arbitrary broadcast program on the EPG display screen 173e using the operation terminal to make a viewing reservation and / or a recording reservation for the broadcast program (S704), the main control unit 101 performs the first separation. The program information data string acquired from the unit 132 is confirmed (S705), and further, the location of the acquisition destination of the broadcast cooperation application linked to the broadcast program for which the viewing reservation and / or the recording reservation is made is confirmed (S706).

After the process of S706, the application control unit 161 transmits a transmission request of the broadcast cooperation application to the predetermined service provider server 400 via the LAN communication unit 121 based on the confirmed URL (S707). The service provider server 400 that has received the transmission request of the broadcast cooperation application performs authentication processing of the broadcast receiving device 100 as necessary based on the control of the application management / distribution execution unit 4103, and then stores the application storage area 4013. The stored predetermined broadcast cooperation application is distributed via the LAN communication unit 421 (S708). Subsequently, the application control unit 161 RAs the predetermined broadcast cooperation application delivered from the service provider server 400 received via the LAN communication unit 121.
It is cached in M104 or storage 110 (S709).

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

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

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

When linking with a mobile information terminal, the mobile information terminal 70 in the same house as the broadcast receiving device 100
There are cases where you want to limit the use of terminal linkage to only 0 (hereinafter this restriction is called the same in-home restriction).
.. For example, in an application for using broadcast cooperation (hereinafter referred to as a broadcast cooperation application), the display screen of the broadcast receiving device 100 and the display screen of the mobile information terminal 700 are closely related, or the broadcast receiving device 100. For example, when the user of the mobile information terminal 700 is surely to watch the displayed advertisement video.

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

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

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

Even if the mobile information terminal 700 is not on the local network, NFC and Blue
By directly communicating with the broadcast receiving device 100 by eTooth, infrared communication, or the like, it can be determined that they exist in the same house. In this case, the communication for acquiring the broadcast cooperation application etc. is
The above-mentioned direct communication may be used, or mobile telephone communication may be used.

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

Further, once it can be confirmed that the mobile information terminal 700 exists in the same house, it may be regarded as existing in the same house until the end of the program, or a certain effective time (for example, 10 minutes).
However, if the effective time has passed, it is not considered to be in the same house unless a new confirmation is made. This effective time is described in, for example, AIT, and is read by the broadcast receiving device 100.

Further, for example, an event signal is set in the broadcast signal at any time during the program.
It is also possible to confirm that the mobile information terminal 700 exists in the same house each time the event signal is received.

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

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

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

FIG. 18A shows the procedure of this embodiment.

First, before linking the terminals, each of the mobile information terminal 700 and the broadcast receiving device 100
Start the linkage control application, which is an application that controls terminal linkage (S1000).
1, S10002). In this state, the mobile information terminal 700 makes a terminal cooperation request to the broadcast receiving device 100 (S1003). Next, acquire AIT from the broadcast signal (S1000)
4). From this AIT information, it is determined whether the target mobile information terminal application has the same in-home restriction (S10006), and if there is a restriction, proceed to the procedure of S10008, and the first stage when the terminal cooperation request is made. Then, the process proceeds to the step of S1009, and it is determined whether or not the mobile information terminal 700 for which the terminal cooperation request has been made is in the same house as the broadcast receiver 100 (S10).
009). As a result of the determination, if it is determined that they are not in the same house, a response of disapproval of cooperation is made to the cooperation control application on the mobile information terminal side, and the process is terminated (S10011).

Here, in the first place, if it is assumed that all terminal cooperation applications have the same in-home restriction, S
The determination of 10006 is not performed and is skipped. The determination of S10006 is performed when there may be both an application having the same in-home restriction and an application not having the same in-home restriction.

If it is determined that the mobile information terminal 700 is in the same home, or if the application has no restrictions in the same home, the process proceeds to S10012 to provide a broadcast cooperation application-related service. This service (S100
In 12), 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 delivered by the broadcast receiving device 100 from the distribution server (S10014, S1001).
5, S10016), what was acquired from the broadcast signal (S10017), broadcast receiver 100
There are things that I remember in. Reception of broadcast cooperation information by the broadcast receiver 100 (S100)
16, S10017) is a broadcast cooperation information distribution request (S1001) from the mobile information terminal 700.
Not only the case according to 3), but also the case where the broadcast receiving device 100 autonomously acquires or the case where the acquisition is based on the occurrence of an event from the broadcast signal may be performed. And the mobile information terminal 70
The distribution of the broadcast cooperation information to 0 (S10018) may also be voluntary from the broadcast receiving device 100 side.

After receiving (acquiring) and distributing a series of broadcast-related information, it is determined whether or not the broadcast receiving device 100 continues to watch the same program (S10019), and if not, the mobile information terminal side. Responds to the cooperation control application that the cooperation is not permitted, and ends the process (S100).
20).

If the viewing is continued, the procedure returns to S1005, and if there is a restriction in the house, it is confirmed whether the mobile information terminal 700 is in the same house (S10009), but the preset valid time has elapsed since the previous confirmation. It is determined whether the confirmation request (S10007) has been generated from the broadcast signal or the distribution server since the previous confirmation (S10008), and if none of the conditions are met, it is determined whether the home is in the same house. No confirmation (S10009) was performed.
The next broadcast cooperation application-related service (S10012) is executed via S10010. Here, the confirmation request (S10008) from the broadcast signal is described to be acquired from the broadcast cooperation information, but here, the event message is also described as being included in the broadcast cooperation information. Further, this confirmation request may be described in the AIT.

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

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

In this way, while executing the broadcast cooperation application-related service (S10012), the portable information terminal 700 receives the broadcast every preset valid time, or every time there is a broadcast signal or a confirmation request from the distribution server. By checking if it is in the same house as the device 100,
It is possible to appropriately execute broadcast-related applications that have the same in-home restrictions. Furthermore, by using the authentication information embedded in the broadcast signal for authentication on the distribution server, the validity of the distribution request can be ensured, and if the authentication information of the broadcast signal is changed as appropriate, the same program can be used. You can also confirm that you are continuing to watch.

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

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

FIG. 18B shows the procedure of this embodiment.

First, before linking the terminals, each of the mobile information terminal 700 and the broadcast receiving device 100
Start the linkage control application, which is an application that controls terminal linkage (S1010).
1, S10102). In this state, the mobile information terminal 700 makes a terminal cooperation request to the broadcast receiving device 100 (S10103). Next, acquire AIT from the broadcast signal (S1010).
4). Information such as a URL related to the distribution server is acquired from this AIT information, and the information is transmitted to the mobile information terminal 700 (S10105). Next, the broadcast receiving device 100 issues a time confirmation request to the distribution server (S10106), and based on this request, the distribution server transmits time information to the broadcast receiving device 100 (S10107). As a result, the authentication key issuance (S10115) in the subsequent stage can be performed according to the time of the distribution server, but it may be omitted if there is no problem with the time lag.

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

First, the mobile information terminal 700 issues an authentication key issuance request or a broadcast cooperation information distribution request to the broadcast receiving device 100 (S10109). The authentication key is used in the broadcast cooperation information distribution request to the distribution server in the subsequent stage (S10125). The broadcast cooperation distribution request in S10109 is a distribution request for information acquired from a broadcast signal, and corresponds to the procedure of S10126 in the subsequent stage.

In any case, when the request for S10109 is issued from the mobile information terminal, it is determined whether or not the application is a broadcast cooperation application having the same in-home restriction (S10111), and if there is a restriction, the next procedure S1011
If not, the procedure of S10112 is skipped and the process proceeds to S10114. If all the broadcast cooperation applications have the same in-home restriction, the determination of S10111 is not performed and the process proceeds to S10112. In S10112, it is determined whether or not the mobile information terminal that issued the request is in the same house, and if not, the terminal cooperation is terminated (S10113). If they are in the same house, the requested procedure, acquisition of broadcast cooperation information from the distribution server (S10125), or acquisition of broadcast cooperation information from the broadcast signal (S10126) is performed. Since acquisition from the broadcast signal may be performed in addition to acquisition from the distribution server, the procedure of S10126 is also described.

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

First, the broadcast receiver 100 issues the authentication key requested by the information linkage terminal 700. At this time, the authentication key includes the time information at the time of issuance within a predetermined time (for example, 1).
It is valid only (0 minutes). The distribution server confirms the authentication information including whether or not the authentication key is within the valid time, and if the authentication is OK, the distribution of the broadcast cooperation information is permitted. After that, the distribution of information is permitted if it is within the valid time, but the distribution is stopped when the valid time has passed. For example, streaming video cannot be viewed after the valid time.

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

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

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

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

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

When the broadcast cooperation information is changed as the program progresses, the change notification may be issued from the broadcast signal (S10110), and the broadcast cooperation information may be acquired as a trigger. In that case, if it is acquired from the distribution server, the broadcast receiving device 100 issues an authentication key to the mobile information terminal (S10115) to notify that there is a change notification. If it is within the valid time, the issuance of the authentication key may be omitted and only the notification of the change notification may be used. In the case of acquisition from a broadcast signal, the broadcast receiving device 100 acquires the information (S10120) and distributes it to the mobile information terminal (S10120). In the case of acquisition from a broadcast signal, it may be confirmed that the mobile information terminal 700 is in the same house for each change notification, and the confirmation is omitted if it is within the valid time as in the second embodiment. It doesn't matter. Here, the change notification from the broadcast signal (S101)
10) is described so as to be acquired from the broadcast cooperation information, but here, the event message is also described as being included in the broadcast cooperation information. Further, this change notification may be described in the AIT.

After receiving (acquiring) and distributing a series of broadcast-related information, it is determined whether or not the broadcast receiving device 100 continues to watch the same program (S10121), and if not, the mobile information terminal side. Responds to the link control application that the link is not permitted, and ends the process (S101).
23). If the viewing is continued, the process returns to S10108 and the loop processing S10127 is continued.

In this way, by including the time information in the authentication key used for authentication of the distribution server and managing the valid time, it can be confirmed that the portable information terminal 700 is in the same house as the broadcast receiving device 100 on a regular basis. It is possible to appropriately execute broadcast-related applications that have the same in-home restrictions.
Furthermore, by using the authentication information embedded in the broadcast signal for authentication on the distribution server,
The legitimacy of the distribution request can be ensured, and if the authentication information of the broadcast signal is changed as appropriate, it can be confirmed that the same program is being continuously viewed.

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

In Examples 2 and 3, the procedure for realizing the same in-home restriction in terminal cooperation has been described, but depending on the broadcast cooperation application, use from outside the house may be permitted. In this embodiment, such a case will be described. For example, when a program such as TV shopping itself is a public relations / promotion, it is desirable for a broadcaster to be able to use a broadcast cooperation application regardless of whether it is inside or outside the house. In the case of such a program, once registered in the broadcast receiving device 100, the use of the broadcast cooperation application may be permitted regardless of whether or not the mobile information terminal 700 is in the house. In this case, the broadcast video itself is converted into streaming data, and the broadcast receiver 1
Convenience will be further enhanced if there is a broadcasting cooperation application that distributes from 00 to the mobile information terminal 700 via the Internet. The streaming data may be encrypted by the broadcast receiving device 100 for copyright protection. Whether or not the broadcast cooperation application permits use from outside the home, including the distribution of the broadcast video outside the home, is described in the data in the broadcast signal (for example, AIT).

The specific procedure is shown in FIG. 18C. Since some of the procedures are common to Examples 2 and 3, the description of the parts overlapping with Examples 2 and 3 will be omitted. When the broadcast receiving device 100 receives a terminal cooperation request (S10203) from outside the home, the broadcast receiving device 100 confirms whether the request source is a registered mobile information terminal if the application is permitted to be used outside the home (S10203). In S10205), the cooperation is permitted. Here, if necessary, authentication may be performed between the mobile information terminal 700 and the broadcast receiving device 100 in order to protect the copyright of the broadcast video and the broadcast cooperation information (the mobile information terminal 700 and the broadcast receiving device 100 may be used for authentication).
S10207). At that time, the authentication may be authentication on the authentication server (S).
10207). Information on the necessity of copyright protection and information on the authentication method for copyright protection are acquired from a broadcast signal (for example, it is described in AIT), and control is performed accordingly. When such information is not stored in the broadcast signal, a predetermined method predetermined in the broadcast receiving device 100 is followed. For example, a predetermined copyright protection process may be performed. If this information is not stored in the broadcast signal, the broadcast receiver 1
It may be stipulated in advance that the copyright protection process is not performed at 00.

Specific examples (1) to (4) of certification for copyright protection are shown below. Only one of the following certifications may be performed. Alternatively, a combination of a plurality of authentications exemplified below may be performed. Further, the authentication exemplified below may be performed in combination with other authentication processes not exemplified below.

(1) Authentication by ID and Password When registering the mobile information terminal 700 in the broadcast receiving device 100, an ID and a password are issued, and the broadcasting receiving device 100 permits cooperation by confirming the ID and the password.

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

(3) Use of authentication server A method of issuing an encryption key for decrypting encrypted video data, etc. from the authentication server.
The mobile information terminal 700 transmits an ID and a password to the authentication server, and acquires an encryption key. In this case, the location information (specifically, URL) of the authentication server is used as a broadcast signal (for example, A).
By acquiring from (described in IT) and transmitting this location information from the broadcast receiving device 100 to the mobile information terminal 700, the safety is further enhanced. Since the video and the like cannot be decrypted unless the mobile information terminal 700 can obtain the encryption key, the broadcast receiving device 100 may request the authentication by the authentication server to authenticate the writing right protection, or the mobile information terminal. The authentication may be completed by notifying the broadcast receiving device 100 from the 700 that the encryption key has been acquired. It is also possible that the authentication server charges the user.

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

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

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

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

A specific procedure in this case is shown in FIG. 18D. Since some of the procedures are the same as those in FIG. 18C, the description of the overlapping parts will be omitted. First, in a state where the mobile information terminal 700 is in the same house as the broadcast receiving device 100, the broadcast receiving device 10 is sent from the mobile information terminal 700.
A terminal cooperation request is made to 0, and the broadcast receiving device 100 permits the cooperation after confirming that the mobile information terminal 700 is in the same house (S10305). Here, if necessary,
In order to protect the copyright of broadcast video and broadcast cooperation information, authentication may be performed between the mobile information terminal 700 and the broadcast receiving device 100 (S10307). At that time, the authentication may be authentication on an external authentication server. Broadcast signal (for example, it is assumed that it is described in AIT) about the necessity of copyright protection and information about the authentication method of copyright protection.
It is obtained from and is controlled accordingly. When such information is not stored in the broadcast signal, a predetermined method predetermined in the broadcast receiving device 100 is followed. For example, a predetermined copyright protection process may be performed. Further, if such information is not stored in the broadcast signal, it may be determined in advance that the broadcast receiving device 100 does not perform the copyright protection process.

Specific examples (5) to (7) of certification for copyright protection are shown below. Only one of the following certifications may be performed. Alternatively, a combination of a plurality of authentications exemplified below may be performed. Further, the authentication exemplified below may be performed in combination with other authentication processes not exemplified below.

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

(6) Use of authentication server A method of issuing an encryption key for decrypting encrypted video data, etc. from the authentication server.
The mobile information terminal 700 transmits an ID and a password to the authentication server, and acquires an encryption key. In this case, the location information (specifically, URL) of the authentication server is used as a broadcast signal (for example, A).
By acquiring from (described in IT) and transmitting this location information from the broadcast receiving device 100 to the mobile information terminal 700, the safety is further enhanced. Since the video and the like cannot be decrypted unless the mobile information terminal 700 can obtain the encryption key, the broadcast receiving device 100 may request the authentication by the authentication server to authenticate the writing right protection, or the mobile information terminal. The authentication may be completed by notifying the broadcast receiving device 100 from the 700 that the encryption key has been acquired. The access to the authentication server may be performed inside or outside the house, but the location information of the authentication server cannot be acquired from the broadcast signal until at a certain point in the program, and the location information is sent to the mobile information terminal 700. If the delivery is limited to the same house, it is possible to set a restriction that the user must be in the same house at that time, and it can also be used to give a premiere to viewing. It is also possible that the authentication server charges the user.

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

If the information stored in the broadcast signal indicates that the copyright protection is required by the predetermined method, and the copyright protection cannot be authenticated by the predetermined method, the terminal cooperation is not permitted. Even if the broadcast signal is not specified and authentication is performed by the default method of the broadcast receiver 100,
If copyright protection cannot be authenticated by the default method, terminal cooperation will not be permitted. Since the procedure after permitting the terminal cooperation is the same as the procedure shown in FIG. 18C, the description thereof will be omitted.

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

In the actual usage situation, it is more desirable to easily know whether or not there is a terminal cooperation application by the program and which terminal cooperation application can be used. In this embodiment, a method of displaying the availability status of the terminal cooperation application will be described.

FIG. 19A shows the launcher screen (173b1) of the broadcast cooperation application when there is a terminal cooperation application.
This is an example of 1). The broadcast cooperation application is displayed with a framed character icon. A broadcast cooperation application (173b12 to 173b14) for the broadcast receiving device 100 linked to the program being viewed and a broadcast cooperation application (173b15 to 173b17) for the mobile information terminal are displayed. In the case of this example, the thickness of the border surrounding the character string and the color inside the frame indicate the status of the app. Main unit applications A and B (173b12, 173b13) and terminal applications A and B (173b15, 173)
b16) is in a usable state, and the main body application C (173b14) and the terminal application (173) are available.
b17) is in an unusable state. The state in which the terminal application cannot be used means that none of the portable information terminals 700 in a state in which communication with the broadcast receiving device 100 has a function of executing the application.

FIG. 19B is a screen after selecting the terminal application A in FIG. 19A. The state of each mobile information terminal 700 with respect to the terminal application A is shown. The mobile information terminal displayed on this screen is a terminal that has been linked with or registered with the broadcast receiving device 100 in the past.

Mobile terminal 1 (173b22) and mobile terminal 2 (173) whose icon border is a solid line
b23) is in a state where it can communicate with the broadcast receiving device 100, and the mobile terminal 3 (173b24) and the mobile terminal 4 (173b25) whose border is a dotted line are not in a state where they can communicate with the broadcast receiving device 100. Shows. In addition, the mobile terminal 1 (173b2) whose icon frame is white.
2) and the mobile terminal 3 (173b24) have a function to execute the terminal application A, and the mobile terminal 2 (173b23) and the mobile terminal 4 (173b25) whose frame is gray do not have a function to execute the terminal application A. It is shown that. Furthermore, if the app is already running on the device, you may use an icon designed to indicate that.

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

FIG. 19C is an example of a launcher screen (173b31) showing a list of broadcast cooperation applications. In addition to the broadcast receiving device 100, icons are shown for each type of mobile information terminal 700. 17
3b32 and 173b33 are icons indicating the broadcast receiving device 100, and 173b34 and 1
73b35 is an icon indicating a smart phone type mobile information terminal 700, and is 173b36.
Is an icon indicating the head-mounted display type personal digital assistant 700. Each app is for the device indicated by the icon.

In FIG. 19C, when the application cannot be used, a mark indicating that the application cannot be used (in this case, a diagonal line mark in a circle) is displayed on the pattern of the device. Further, regarding the broadcast receiving device 100, if the application is already running, a mark indicating that fact (in this case, a dot in a circle) may be superimposed and displayed. With this display, it is possible to prevent a useless operation of advancing the launcher procedure even though the execution has already been performed. In the case of the mobile information terminal 700, it is also possible to display a mark indicating that the application is being executed on all terminals that are in a state of being able to communicate with the broadcast receiving device and that the application can be executed.

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

Furthermore, it is desirable to have a display method that shows that there is a broadcast cooperation application when the situation changes without starting the launcher 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 mobile information terminal 700. In that case, when the execution status of the application changes, the icon is displayed for a predetermined time and the status at that time is displayed.

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

FIG. 19F is a display screen (10401) on the mobile information terminal 700. Mobile information terminal 70
When requesting terminal cooperation from 0, it is convenient to know from a list which broadcast cooperation application can be used with which broadcast receiving device 100. An example of the list is shown in FIG. 19F (104).
02). This table shows which broadcast receiving device 100 in the home can use the broadcast cooperation application corresponding to the program to be examined. Further, if the status of each broadcast receiving device 100 is also displayed, the convenience is further enhanced especially when the broadcast receiving device 100 is used from outside the house. In this example, while receiving the program,
A display example such as receiving another program, being vacant, and having another program reserved (when recording of another program is reserved from the middle of the program) is shown. Here, when a plurality of tuners exist in the broadcast receiving device 100, the convenience is further different if the status is displayed for each of the plurality of tuners. Table 102
In 02, the branch number indicates the distinction between the tuners in the same device. For example, receiver B
-1, The receiving device B-2 is a tuner in the same broadcast receiving device 100. In the case of terminal cooperation, if the broadcast video and audio can be delivered as streaming data, the broadcast receiver 10
It is not necessary to use the video unit of 0, and if the tuner in the broadcast receiving device 100 can be used, the broadcast can be used, so it is convenient to know the usage status of each tuner.

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

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