## Abstract

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.

## Claims

### Claim 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 broadcast 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 on basis of 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 apparatus via a network;
a video converter configured to convert the broadcast program video decoded by the broadcast video decoder into a high-quality video having a higher quality picture than the broadcast program video by a converting processing selecting among a plurality of processing including a first processing combining the decoded broadcast program video and the additional data acquired from the predetermined server apparatus by executing the acquired predetermined application and a second processing combining the decoded broadcast program video and an interpolation data generated by the broadcast receiving apparatus;
a display capable of displaying the high-quality video; and
a controller configured to control the video converter,
wherein the controller is configured to select the second processing as the converting processing when network traffic is congested between the broadcast receiving apparatus and the predetermined server apparatus and select the first processing as the converting processing when network traffic is not congested between the broadcast receiving apparatus and the predetermined server apparatus.

### Claim 2 (depends on 1)

The broadcast receiving apparatus according to claim 1, wherein
the broadcast receiving apparatus further comprises:
a billing processor 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 processor confirms that the user of the broadcast receiving apparatus has paid the charge for use of service to the predetermined service provider, the video converter converts the broadcast program video decoded by the broadcast video decoder into the high-quality video by use of the additional data acquired by the application processor.

### Claim 3 (depends on 1)

The broadcast receiving apparatus device according to claim 1, wherein
the additional data is differential data for increasing a frame rate of the broadcast program video decoded by the broadcast video decoder, and
the video converter converts the broadcast program video decoded by the broadcast video decoder into a high-quality video of a higher frame rate.

### Claim 4

A video display method in a broadcast receiving apparatus receiving a digital broadcast service which is capable of executing an application in cooperation with a broadcast program, the method comprising:
a broadcast receiving step of receiving a broadcast wave of the digital broadcast service;
a separation step of separating at least video information of a broadcast program and application-related information from the received broadcast wave;
a broadcast video decoding step of decoding the video information of the broadcast program;
an application acquisition step of acquiring a predetermined application on basis of location information acquired by referring to the application-related information;
an application execution step executing the acquired predetermined application to acquire additional data from a predetermined server apparatus via a network;
a video conversion step of converting the broadcast program video decoded in the broadcast video decoding step into a high-quality video having a higher quality picture than the broadcast program video by a converting processing selected among a plurality of processing including a first processing combining the decoded broadcast program video and the additional data acquired from the predetermined server apparatus by executing the acquired predetermined application and a second processing combining the decoded broadcast program video and an interpolation data generated by the broadcast receiving apparatus; and
a display step of displaying the high-quality video,
wherein the converting processing in the video conversion is selected based on the second processing as the converting processing when network traffic is congested between the broadcast receiving apparatus and the predetermined server apparatus and select the first processing as the converting processing when network traffic is not congested between the broadcast receiving apparatus and the predetermined server apparatus.
