Abstract

A broadcast receiving apparatus which can change the operation of a Java application depending on whether a broadcast is being viewed or recorded content is being reproduced. Control information, including first control information which controls startup of the Java application at the time of broadcasting and second control information which controls startup of a Java application that has been recorded into a secondary storage unit, is acquired from a broadcast signal; an AM controls startup of the Java application in accordance with the first control information at the time of broadcasting, and controls startup of the Java application in accordance with the second control information in the case of executing a Java application stored in the secondary storage unit.

Claims

1. A broadcast receiving apparatus comprising:

a receiving unit operable to receive a broadcast signal that includes a broadcast service, the broadcast service including video and audio information, an application program, and control information for controlling startup of the application program;

a video and audio reproduction unit operable to reproduce the video and audio information included in the broadcast service;

an application extraction unit operable to extract the application program, the application program being executed in synchronization with the video and audio information reproduced by said video and audio reproduction unit;

an application execution unit operable to execute the application program included in the broadcast service in accordance with the control information included in the broadcast service;

a secondary storage unit which has an area that stores information even when the power source to said broadcast receiving apparatus is cut off; and

a recording unit operable to record the broadcast service including the video and audio information and application program into said secondary storage unit,

wherein said control information includes first control information for controlling startup of the application program at the time of broadcasting, and second control information for controlling, after the application program has been recorded into said secondary storage unit, startup of the recorded application program;

said application execution unit is operable to control startup of the application program associated with the first control information in accordance with the first control information, at the time of broadcasting; and

said application execution unit is operable to control startup of the application program in accordance with the second control information associated with the application program, in the case of executing an application program that has been recorded into said secondary storage unit.

2. The broadcast receiving apparatus according to claim 1,

wherein, during reproduction by said video and audio reproduction unit, in the case where said application extraction unit extracts the application program recorded into said secondary storage unit, said application extraction unit is operable to extract the application program for which the second control information, which is included in the control information recorded into said secondary storage unit, indicates the application is to be started automatically.

3. The broadcast receiving apparatus according to claim 1,

wherein, during reproduction by said video and audio reproduction unit, in the case where said application extraction unit extracts the application program recorded into said secondary storage unit, said application extraction unit is operable to extract the application program for which the second control information and the first control information, which are included in the control information recorded into said secondary storage unit, indicate the application is to be started automatically.
