Broadcast receiving device
A broadcast receiving device is provided with: a broadcast receiving unit which receives a digital broadcast signal including broadcast program video and application-related information; a storage unit which stores the received broadcast program video and application-related information; a video decoding unit which decodes the video; an application acquisition unit which acquires an application on the basis of location information included in the application-related information; an application execution unit which executes the acquired application; an output unit which is able to output the video; and a control unit for reproducing and decoding the broadcast program video from the storage unit, reproducing the application-related information from the storage unit, acquiring the application on the basis of the location information included in the reproduced application-related information, and executing the acquired application.
1. A broadcast receiving device which is capable of executing an application in cooperation with a broadcast program and capable of receiving a digital broadcast signal of a digital broadcast, comprising:
a broadcast receiver that receives the digital broadcast signal including a broadcast program video and application-related information;
a storage that stores application expiration time limit information and location information included in the application-related information;
a video decoder that decodes the broadcast program video;
an application acquisition processor configured to acquire a predetermined application from a server, on a network, on the basis of the location information;
an application execution processor configured to execute the acquired predetermined application to generate an application-executed video; and
a controller configured to control the application acquisition processor to acquire the predetermined application on the basis of the location information reproduced from the storage, control the video decoder to decode the broadcast program video, and control the application execution processor to execute the acquired predetermined application,
wherein the controller is further configured to control output of a decoded video of the broadcast program video or of the application-executed video, and
wherein the controller is further configured to control the application execution processor to not execute the predetermined application upon determining that the predetermined application has already been acquired and an expiration time limit indicated in the application expiration time limit information has already expired, and to control the application acquisition processor to not acquire the predetermined application from the server upon determining that the predetermined application has not been acquired and the expiration time limit indicated in the application expiration time limit information has already expired.
2. The broadcast receiving device according to claim 1 ,
wherein the application expiration time limit information is information indicating a time limit within which the application already acquired can be executed.
3. The broadcast receiving device according to claim 1 , wherein the controller is further configured to control the output of the decoded video of the broadcast program video or of the application-executed video to a display device.
4. The broadcast receiving device according to claim 1 , wherein the application expiration time limit information is information indicating the expiration time limit within which the predetermined application can be acquired.
