Abstract

Disclosed herein is a reception apparatus for receiving AV content, including: a receiver configured to trigger information for controlling processing associated with an application program to be executed in conjugation with a progress of the AV content; a holder configured to hold the application program; and a controller configured to control a state of a first application program depending on whether first trigger information for specifying processing associated with the first application program held in the holder as a subject of control has been received in synchronization with a predetermined reception timing.

First claim

What is claimed is:

1. A reception apparatus for receiving audio/video (AV) content, comprising:
reception means for receiving first control information listing an application to be executed in interlocked relation with a progress of said AV content and receiving, after receiving the first control information, second control information listing at least one application to be executed in interlocked relation with a progress of the AV content;
control means for
determining whether said application listed by said received first control information is listed in the second control information;
in response to a determination that said application listed by the first control information is not listed in the second control information, terminating said application listed in the first control information
in response to a determination that said application listed by the first control information is listed in the second control information, performing processing associated with said application listed by the first control information.

2. A reception method for a reception apparatus for receiving audio/video (A/V) content, comprising:
receiving, by circuitry of said reception apparatus, first control information listing an application to be executed in interlocked relation with a progress of said AY content and receiving, after receiving the first control information, second control information listing at least one application to be executed in interlocked relation with a progress of the AV content: and
determining, by said circuitry, whether said application listed by said received first control information is listed in the second control information;
in response to a determination that said application listed by the first control information is not listed in the second control information, terminating said application listed in the first control information; and
in response to a determination that said application listed by the first control information is listed in the second control information, performing processing associated with said application listed in the first control information.

3. A non-transitory computer-readable storage medium storing a program for controlling a reception apparatus for receiving audio/video (A/V) content, said program causing a computer of said reception apparatus to execute processing comprising;
receiving first control information listing an application to be executed in interlocked relation with a progress of said AV content and receiving, after receiving the first control information, second control information listing at least one application to be executed in interlocked relation with a progress of the AV content; and
determining whether said application listed by said received first control information is listed in the second control information
in response to a determination that said application listed by the first control information is not listed in the second control information, terminating said application listed in the first control information
in response to a determination that said application listed by the first control information is listed in the second control information, performing processing associated with said application listed in the first control information.

4. A transmission apparatus for transmitting audio/video (AV) content, comprising:
transmission means for transmitting to a reception apparatus said first control information listing an application to be executed on said reception apparatus in interlocked relation with a progress of said AV content and transmitting to the reception apparatus, after transmitting the first control information, second control information Listing at least one application to be executed in interlocked relation with a progress of the AV content
wherein said reception apparatus
determines whether said application listed by said first control information is listed in the second control information
in response to a determination that said application listed by the first control information is not listed in the second control information, terminates said application listed in the first control information;
in response to a determination that said application listed by the first control information is listed in the second control information, performs processing associated with said application listed in the first control information.

5. A transmission method for a transmission apparatus for transmitting audio/video (AV) content, comprising:
transmitting to a reception apparatus, by circuitry of said transmission apparatus, first control information listing an application to be executed on said reception apparatus in interlocked relation with a progress of said AV content and transmitting to the reception apparatus, after transmitting the first control information, second control information listing at least one application to be executed in interlocked relation with a progress of the AV content,
wherein reception apparatus determines whether said application listed by said first control information is listed in the second control information
in response to a determination that said application listed by the first control information is not listed in die second control information, terminates said application listed in the first control information and
in response to a determination that said application listed by the first control information is listed in the second control information, performs processing associated with said application listed in the first control information.

6. A non-transitory computer-readable storage medium storing a program for controlling a transmission apparatus for transmitting audio/video (AV) content, said program causing a computer of said transmission apparatus to execute processing comprising: transmitting to a reception apparatus first control information listing an application to be executed on said reception apparatus in interlocked relation with a progress of said AV content and transmitting to the reception apparatus, after transmitting the first control information, second control information listing at least one application to be executed in interlocked relation with a progress of the AV content,
wherein said apparatus determines whether said application listed by said first control information is listed in the second control information;
in response to a determination that said application listed by the first control information is not listed in the second control information, terminates said application listed in the first control information; and
in response to a determination that said application listed by the first control information is listed in the second control information, performs processing associated with said application listed in the first control information.

7. A broadcasting system comprising: a transmission apparatus for transmitting AV content, and
a reception apparatus for receiving said transmitted AV content;

wherein said transmission apparatus includes
a transmitter configured to transmit first control information listing an application to be executed on said reception apparatus in interlocked relation with a progress of said AV content and to transmit after transmitting the first control information, second control information listing at least one application to be executed in interlocked relation with a progress of the AV content; and
said reception apparatus includes
a receiver configured to receive said first control information listing said application to be executed is interlocked relation with said progress of said AV content and to receive, after receiving the first control information, the second control information listing the at least one application to be executed in interlocked relation
