Broadcast reception device and video display method
A broadcast reception device receives a digital broadcast service capable of executing an application cooperating with a broadcast program, and is provided with: a broadcast reception unit which receives broadcast waves of the digital broadcast service; a separation unit which separates video information relating to the broadcast program and application-related information from the received broadcast waves; a broadcast video decoding unit which decodes the video information relating to the broadcast program; 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 and acquires additional data from a server device; a video conversion unit which converts broadcast program video decoded by the broadcast decoding unit into high-quality video having a higher quality than the video using the acquired additional data; and a display unit which is able to display the high-quality video.
1. A broadcast receiving apparatus receiving a digital broadcast service which is capable of executing an application in cooperation with a broadcast program, comprising:
a receiver configured to receive a broadcast wave of the digital broadcast service;
a separator configured to separate at least video information of a broadcast program and application-related information from the received broadcast wave;
a broadcast video decoder configured to decode the video information of the broadcast program;
an application controller configured to acquire a predetermined application based on location information acquired by referring to the application-related information;
an application processor configured to execute the acquired predetermined application to acquire additional data from a predetermined server via a network;
a video processor configured to perform a high-quality video conversion processing for making video of the broadcast program decoded by the broadcast video decoder to have higher quality, using the additional data acquired by the application processor; and
a display configured to display the video subjected to the high-quality video conversion processing, wherein
the application controller acquires the predetermined application when determining, based on information contained in the application-related information, that the broadcast receiving apparatus can execute the high-quality video conversion processing using the additional data, and
in response to video viewing reservation and/or video recording reservation of a broadcast program performed by a user of the broadcast receiving apparatus, the application controller acquires the predetermined application cooperative with the broadcast program of the video viewing reservation and/or the video recording reservation having been performed by the user before a broadcast start time of the broadcast program of the video viewing reservation and/or the video recording reservation.
2. The broadcast receiving apparatus according to claim 1 , further comprising:
a billing process unit configured to confirm whether or not a user of the broadcast receiving apparatus has paid a charge for use of service to a predetermined service provider;
wherein in a case where the billing process unit confirms that the user of the broadcast receiving apparatus has paid the charge for use of service to the predetermined service provider, the video processor performs the high-quality video conversion processing on the broadcast program decoded by the broadcast video decoder using the additional data acquired by the application processor.
3. The broadcast receiving apparatus according to claim 1 , wherein
the additional data is differential data for improving a frame rate of the broadcast program decoded by the broadcast video decoder, and
the video processor converts the broadcast program decoded by the broadcast video decoder into a high-quality video of a higher frame rate.
4. The broadcast receiving apparatus according to claim 1 , wherein
the additional data is differential data for improving a quantization bit rate of the broadcast program decoded by the broadcast video decoder, and
the video processor converts the broadcast program decoded by the broadcast video decoder into a high-quality video of a higher quantization bit rate.
5. The broadcast receiving apparatus according to claim 1 , wherein
the additional data is differential data for improving a resolution of the broadcast program decoded by the broadcast video decoder, and
the video processor converts the broadcast program decoded by the broadcast video decoder into a high-quality video of a higher resolution.
6. A method of making video of broadcast program to have higher quality using an application cooperative with the broadcast program in a broadcast receiving apparatus, comprising:
receiving a broadcast wave of a digital broadcast service;
separating at least video information of a broadcast program and application-related information from the received broadcast wave;
decoding the video information of the broadcast program;
acquiring a predetermined application based on location information acquired by referring to the application-related information;
executing the acquired predetermined application to acquire additional data from a predetermined server via a network;
performing a high-quality video conversion processing for making video of the decoded broadcast program to have higher quality using the acquired additional data; and
displaying the video subjected to the high-quality video conversion processing, wherein
acquiring the predetermined application when determining, based on information contained in the application-related information, that the broadcast receiving apparatus can execute the high-quality video conversion processing using the additional data, and
in response to video viewing reservation and/or video recording reservation of a broadcast program performed by a user of the broadcast receiving apparatus, acquiring the predetermined application cooperative with the broadcast program of the video viewing reservation and/or the video recording reservation having been performed by the user before a broadcast start time of the broadcast program of the video viewing reservation and/or the video recording reservation.
