Abstract

Disclosed herein is a reception apparatus for receiving transmitted AV (Audio/Video) content, including: an extractor configured to extract trigger information associated with control of an application program to be executed in conjugation with the AV content; and a controller configured, in response to a command indicated by the extracted trigger information, to control execution of the application program and, if a video of the AV content is switched, execute any one of continuation and termination of the application program that is active.

Claims

1. A reception apparatus for receiving transmitted AV (Audio/Video) content, comprising:

extraction means for extracting trigger information transmitted with said AV content and associated with control of an application program to be executed in conjugation with said AV content; and

control means for controlling, in response to a command indicated by said extracted trigger information, execution of said application program and, if a video of said AV content has been switched, executing any one of continuation and termination of said application program that is active.

2. The reception apparatus according to claim 1, wherein, if a video of said AV content is switched on the basis of execution continuation information corresponding to an application program, said control means executes any one of continuation and termination of said application program that is active.

3. The reception apparatus according to claim 1, wherein said execution continuation information includes any one of:

ES-bound in which a continuation scope of execution of said application program that is active with a video of AV content switched is within a same ES (Elementary Stream);

service-bound in which a continuation scope of execution of said application program that is active with a video of AV content switched is within a same service;

provider-bound in which a continuation scope of execution of said application program that is active with a video of AV content switched is within a same broadcasting organization; and

un-bound in which a continuation scope of execution of said application program that is active with a video of AV content switched is not arranged.

4. The reception apparatus according to claim 2, wherein said execution continuation information is included in said trigger information.

5. The reception apparatus according to claim 2, wherein said execution continuation information is included in said application program.

6. The reception apparatus according to claim 1, wherein said control means further controls acquisition and launching of said application program, event firing in said application program that is active, suspension of said application program that is active, and termination of said application program that is active in accordance with a command indicated by said extracted trigger information.

7. A reception method for a reception apparatus for receiving transmitted AV (Audio/Video) content, comprising the steps of:

extracting, by said receiving apparatus, trigger information transmitted with said AV content and associated with control of an application program to be executed in conjugation with said AV content;

controlling execution, by said reception apparatus, of said application program in response to a command indicated by said extracted trigger information; and

controlling any one of continuation and termination of execution, by said reception apparatus, of said application program that is active if a video of said AV content has been switched.

8. A program for controlling a reception apparatus for receiving transmitted AV content, said program making a computer of said reception apparatus execute processing comprising the steps of:

extracting, by said receiving apparatus, trigger information transmitted with said AV content and associated with control of an application program to be executed in conjugation with said AV content;

controlling execution, by said reception apparatus, of said application program in response to a command indicated by said extracted trigger information; and

controlling any one of continuation and termination of execution, by said reception apparatus, of said application program that is active if a video of said AV content has been switched.

9. A transmission apparatus for transmitting AV content, comprising:

transmission means for transmitting, along with said AV content, trigger information associated with control of an application program to be executed in a reception apparatus in conjugation with said AV content, wherein

said trigger information includes execution continuation information for determining, if a video of said AV content is switched when said application program is active in said reception apparatus, any one of continuation and termination of execution of said application program that is active.

10. The transmission apparatus according to claim 9, wherein, in said reception apparatus, said execution continuation information includes any one of

ES-bound in which a continuation scope of execution of said application program that is active with a video of AV content switched is within a same ES (Elementary Stream);

service-bound in which a continuation scope of execution of said application program that is active with a video of AV content switched is within a same service;

provider-bound in which a continuation scope of execution of said application program that is active with a video of AV content switched is within a same broadcasting organization; and

un-bound in which a continuation scope of execution of said application program that is active with a video of AV content switched is not arranged.

11. The transmission apparatus according to claim 9, wherein a command indicated by said trigger information includes at least one of commands for controlling acquisition and launching of said application program, event firing in said application program that is active, suspension of said application program that is active, and termination of said application program that is active.

12. A transmission method for a transmission apparatus for transmitting AV (Audio/Video) content, comprising the step of:

transmitting, by said transmission apparatus, along with said AV content, trigger information associated with control of an application program to be executed in a reception apparatus in conjugation with said AV content;

wherein

said trigger information includes execution continuation information for determining, if a video of said AV content is switched when said application program is active in said reception apparatus, any one of continuation and termination of execution of said application program that is active.

13. A program for controlling a transmission apparatus for transmitting AV (Audio/Video) content, said program making a computer of said transmission apparatus execute processing comprising the step of:

transmitting, by said transmission apparatus, along with said AV content, trigger information associated with control of an application program to be executed in a reception apparatus in conjugation with said AV content;

wherein

said trigger information includes execution continuation information for determining, if a video of said AV content is switched when said application program is active in said reception apparatus, any one of continuation and termination of execution of said application program that is active.

14. A broadcasting system comprising:

a transmission apparatus for transmitting AV (Audio/Video) content; and

a reception apparatus for receiving said transmitted AV content, wherein

said transmission apparatus has

transmission means for transmitting, along with said AV content, trigger information associated with control of an application program to be executed in a reception apparatus in conjugation with said AV content; and

said reception apparatus has

extraction means for extracting trigger information transmitted with said AV content and

control means for controlling, in response to a command indicated by said extracted trigger information, execution of said application program and, if a video of said AV content has been switched, executing any one of continuation and termination of said application program that is active.
