Abstract

A broadcast receiver is configured to receive a broadcast wave of a digital broadcast service; separate at least a video image related to a broadcast program, electronic program guide information, and application-related information from the received broadcast wave; reproduce the video image related to the broadcast program; form an electronic program guide screen based on the electronic program guide information; acquire an application based on location information by referring to the application-related information; execute the application and outputs an application execution video image; and display the video image related to the broadcast program, the electronic program guide screen, or the application execution video image. The electronic program guide screen indicates information relating to applications to be executed in cooperation with the broadcast program.

Claims (18)

1. A broadcast receiver for receiving a digital broadcast service that enables an application to be executed in cooperation with a broadcast program, the broadcast receiver comprising:

a tuner configured to receive a broadcast wave of the digital broadcast service which includes at least a video image related to the broadcast program, electronic program guide information, and application-related information;

processing circuitry configured to:

separate at least the video image related to the broadcast program, the electronic program guide information, and the application-related information from the received broadcast wave received by the tuner;

reproduce the video image related to the broadcast program;

generate an electronic program guide indication based on the electronic program guide information;

acquire a predetermined application based on location information acquired by referring to the application-related information; and

execute the acquired predetermined application and output an application execution video image; and

a display configured to display the video image related to the broadcast program, the electronic program guide indication, or the application execution video image, wherein:

the digital broadcast service which is received by the broadcast receiver sets whether or not an application to be executed in cooperation with the broadcast program is provided with the broadcast program and whether or not a cooperative operation is further possible between the application and a portable information terminal, for each of the broadcast programs,

the processing circuitry generates the electronic program guide indication, which indicates a title of the broadcast program together with a first mark indicating that the application is provided with broadcast programs, each of which is set as providing the application, by the digital broadcast service,

the processing circuitry generates the electronic program guide indication, which indicates a title of the broadcast program together with the first mark and/or a second mark indicating that the cooperative operation is possible between the application and the portable information terminal, for broadcast programs each of which is set as being further possible for the cooperative operation between the application and the portable information terminal,

the display displays the electronic program guide indication,

the application-related information contains an application profile information that indicates a function requested to execute the application,

the processing circuitry refers to the application profile information, and determines whether the broadcast receiver has a function regarding the cooperative operation requested for executing the application or not,

the processing circuitry generates at least one of the first mark or the second mark for the broadcast program with which the application is provided in a case where it is determined that the broadcast receiver has the function requested for executing the application, and

the processing circuitry does not generate the first mark and the second mark, even though the broadcast program is provided with the application, in a case where it is determined that the broadcast receiver does not have the function requested for executing the application.

2. The broadcast receiver according to claim 1 , wherein, in a case where the broadcast program is a broadcast program capable of performing a cooperative operation between the application and the portable information terminal, the processing circuitry generates the electronic program guide indication, which indicates the title of the broadcast program, the first mark, and the second mark, together with a two-dimensional bar code that can be read by the portable information terminal and includes URL information of an acquisition source of the application provided to the portable information terminal.
