Abstract

The present invention provides a digital broadcast receiver capable of executing functions having higher added values. The broadcast receiver receives a broadcast wave of a digital broadcast service, controls an operation including activation and end of an application that is in cooperation with a broadcast program based on application-related information, and selects control relating to reactivation of the application based on a user's operation. If activation of the application is requested after the end of the application, the broadcast receiver controls the reactivation or non-reactivation of the application in accordance with the selection of control by the user.

Claims (26)

1. A broadcast receiving apparatus, comprising:

a tuner configured to receive, via a broadcast wave, first video image information of a broadcast program and application-related information relating to applications capable of being executed in cooperation with the broadcast program;

a first decoder configured to decode the first video image information of the broadcast program of a selected channel included in the broadcast wave received by the tuner to generate a first video image of the broadcast program;

an application processor configured to acquire the application-related information from the broadcast wave received by the tuner, acquire an application based on location information included in the application-related information, and execute the acquired application in the broadcast receiving apparatus to acquire second video image information of a video content via a network;

a second decoder configured to decode the second video image information acquired via a network by executing the acquired application to generate a second video image of the video content on the network;

a video processor configured to superimpose the first video image generated by the first decoder and the second video image generated by the second decoder;

a display configured to display the first video image and/or the second image; and

a controller,

wherein

the controller is configured to:

in a case where the location information specifies that an application is to be acquired from a broadcast wave, acquire an application via the broadcast wave based on the location information;

control the video processor such that a state transitions from a first display state in which the first video image is displayed on the display, to a second display state in which the display displays the first and second video images superimposed by the video processor; and

in the second display state, change the size of the first video image or the size of the second video image.

2. A video image presentation method using an application in a broadcast receiving apparatus, comprising the steps of:

receiving first video image information of a broadcast program and application-related information relating to applications capable of being executed in cooperation with the broadcast program via a broadcast wave;

decoding the first video image information of the broadcast program of a selected channel included in the broadcast wave to generate a video image of the broadcast program;

acquiring application-related information from the broadcast wave;

acquiring an application based on location information included in the application-related information via the broadcast wave, when the location information specifies acquiring an application from the broadcast wave;

executing the acquired application in the broadcast receiving apparatus;

acquiring second video image information of a video content via a network by executing the acquired application;

decoding the second video image information to generate a second video image of the video content on the network;

superimposing the first video image and the second video image;

controlling a display to be in a first display state in which the first video image is displayed;

controlling the display to be in a second display state in which the superimposed image of the first video image and the second video image are displayed;

transitioning a state of the display from the first display state to the second display state according to a user operation; and

changing, in the second display state, the size of the first video image or the size of the second video image.
