Abstract

[Object] The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method capable of limiting use of broadcast resources by a predetermined application. [Solving Means] There is provided a reception apparatus including: a control information obtaining unit that obtains first control information for controlling an operation of a first application, the first application being capable of requesting use of a broadcast resource transmitted via a digital broadcasting signal; and an application controller that controls, when the first application requests use of the broadcast resource, the use of the broadcast resource by the first application on the basis of the first control information.

Claims

1. (canceled)

2. A reception apparatus, comprising:

circuitry configured to;

receive first broadcast resource, application control information, and a first application which uses the first broadcast resource, via broadcast communication or broadband communication;

display the first application with the first broadcast resource;

determine, in response to a change of a first broadcast service related to the first broadcast resource, whether the first application is to be terminated or not, based on the application control information; and

terminate the first application when the first application is determined, in response to the change of the first broadcast service based on the application control information, to be terminated.

3. The reception apparatus according to claim 2, wherein

the change of the first broadcast service is performed based on a channel selection by the first application.

4. The reception apparatus according to claim 2, wherein

the circuitry is further configured to receive a second broadcast resource via the broadcast communication, and

the change of the first broadcast service corresponds to changing from the first broadcast service to a second broadcast service related to the second broadcast resource.

5. The reception apparatus according to claim 4, wherein

the first application is determined, in response to the change of the first broadcast service based on the application control information, to be terminated, and

the circuitry is further configured to:

receive a second application, which uses the second broadcast resource, via the broadcast communication or the broadband communication; and

launch the second application when the first application is terminated.

6. The reception apparatus according to claim 4, wherein

the application control information includes permission information which indicates whether the first application is permitted to use the second broadcast resource.

7. The reception apparatus according to claim 4, wherein

the application control information includes at least a first trigger parameter table (TPT) for the first application, and

the circuitry is further configured to determine whether the first application is permitted to use the second broadcast resource based on comparison between the first TPT for the first application and a second TPT for another application which is permitted to use the second broadcast resource.

8. The reception apparatus according to claim 2, wherein

the first broadcast resource is displayed on a portion of a screen, and

the first application is displayed on a margin of the screen.

9. The reception apparatus according to claim 8, wherein

the first application is displayed in a manner that the first application on the margin of the screen is adjacent to at least two sides of the portion of the screen on which the first broadcast resource is displayed.

10. The reception apparatus according to claim 2, wherein

the application control information indicates one or more attributes which are used for preferential cache of the first application in a cache memory.

11. A reception method of a reception apparatus, the method comprising:

receiving first broadcast resource, application control information, and a first application which uses the first broadcast resource, via broadcast communication or broadband communication;

displaying the first application with the first broadcast resource;

determining, by circuitry of the reception apparatus in response to a change of a first broadcast service related to the first broadcast resource, whether the first application is to be terminated or not, based on the application control information; and

terminating, by the circuitry of the reception apparatus, the first application when the first application is determined, in response to the change of the first broadcast service based on the application control information, to be terminated.

12. A transmission apparatus comprising:

circuitry configured to

generate application control information corresponding to a first application, the first application being capable of using a first broadcast resource; and

transmit the application control information via broadcast communication or broadband communication,

wherein

the application control information includes information to

cause display of the first application with the first broadcast resource,

cause determination, in response to a change of a first broadcast service related to the first broadcast resource, of whether the first application is to be terminated or not, and

cause termination of the first application when the determination, in response to the change of the first broadcast service based on the application control information, indicates that the first application is to be terminated.

13. The transmission apparatus according to claim 12, wherein

the change of the first broadcast service corresponds to a channel selection by the first application.

14. The transmission apparatus according to claim 12, wherein

the change of the first broadcast service corresponds to changing from the first broadcast service to a second broadcast service related to a second broadcast resource.

15. The transmission apparatus according to claim 14, wherein,

the application control information includes information to, when the determination, in response to the change of the first broadcast service based on the application control information, indicates that the first application is to be terminated:

cause reception of a second application, which uses the second broadcast resource, via the broadcast communication or the broadband communication; and

cause launch of the second application when the first application is terminated.

16. The transmission apparatus according to claim 14, wherein

the application control information includes permission information which indicates whether the first application is permitted to use the second broadcast resource.

17. The transmission apparatus according to claim 14, wherein

the application control information includes at least a first trigger parameter table (TPT) for the first application to cause determination of whether the first application is permitted to use the second broadcast resource based on comparison between the first TPT for the first application and a second TPT for another application which is permitted to use the second broadcast resource.

18. The transmission apparatus according to claim 12, wherein

the application control information includes information to

cause display of the first broadcast resource on a portion of a screen, and

cause display of the first application on a margin of the screen.

19. The transmission apparatus according to claim 18, wherein

the application control information includes information to

cause the display of the first application in a manner that the first application on the margin of the screen is adjacent to at least two sides of the portion of the screen on which the first broadcast resource is displayed.

20. The transmission apparatus according to claim 12, wherein

the application control information indicates one or more attributes which are used for preferential cache of the first application in a cache memory.

21. A transmission method for a transmission apparatus, the method comprising:

generating application control information corresponding to a first application, the first application being capable of using a first broadcast resource; and

transmitting the application control information via broadcast communication or broadband communication,

wherein

the application control information includes information to

cause display of the first application with the first broadcast resource,

cause determination, in response to a change of a first broadcast service related to the first broadcast resource, of whether the first application is to be terminated or not, and
