Abstract

The present technology relates to a reception apparatus, a reception method, a transmission apparatus and a transmission method in which NRT service is provided in digital broadcasting using an IP transmission method. There is provided a reception apparatus including: a channel selection control unit that performs a channel selection control of channel-selecting digital broadcasting using the IP transmission method; an acquisition control unit that controls acquisition of an application delivered through broadcasting or communication in the digital broadcasting based on signaling information transmitted at a layer higher than an IP layer in a protocol layer of the IP transmission method; and an application execution unit that executes the application acquired. The present technology is applicable to a television receiver, for example.

First claim

The invention claimed is:

1. A reception apparatus, comprising:
circuitry configured to
select a channel of digital broadcasting using an IP (Internet Protocol) transmission method, the channel being identifiable by an IP address;
in response to control information received from the channel of the digital broadcasting for triggering acquisition of an application,
obtain application control information for the application from the channel of the digital broadcasting or from communication through a network, and
obtain signaling information for the channel from the channel of the digital broadcasting;

control acquisition of a whole or a portion of the application that is identified in the application control information using the digital broadcasting or the communication through the network as indicated in the signaling information after obtaining the application control information and the signaling information; and
execute the application after the application is acquired by the reception apparatus.

2. The reception apparatus according to claim 1 , wherein
the application is executed in conjunction with an AV content provided as a broadcasting service in the digital broadcasting.

3. The reception apparatus according to claim 2 , wherein
the application is provided as a service same as or different from the broadcasting service.

4. The reception apparatus according to claim 1 , wherein
the application includes a plurality of components respectively identified in the application control information, and
the circuitry is configured to control acquisition of the plurality of components delivered using the broadcasting or the communication through the network as respectively indicated in the signaling information.

5. The reception apparatus according to claim 1 , wherein
the signaling information includes information for acquiring another signaling information for another channel of the digital broadcasting when the application is to be acquired from the another channel of the digital broadcasting.

6. The reception apparatus according to claim 1 , wherein
the application is provided as an independent broadcasting service in the digital broadcasting.

7. The reception apparatus according to claim 1 , wherein
the application includes entry point information and one or more resources, and
the circuitry is configured to control acquisition of the one or more resources delivered using the broadcasting or the communication through the network based on location information of the one or more resources included in the entry point information and the signaling information.

8. The reception apparatus according to claim 7 , wherein
the signaling information includes a URL (Uniform Resource Locator) of the entry point information, and
the circuitry is configured to acquire the entry point information based on the URL of the entry point information.

9. A reception method for a reception apparatus, comprising:
selecting a channel of digital broadcasting using an IP (Internet Protocol) transmission method, the channel being identifiable by an IP address;
in response to control information received from the channel of the digital broadcasting for triggering acquisition of an application,
obtaining, by circuitry of the reception apparatus, application control information for the application from the channel of the digital broadcasting or from communication through a network, and
obtaining, by the circuitry of the reception apparatus, signaling information for the channel from the channel of the digital broadcasting;

controlling, by the circuitry of the reception apparatus, acquisition of a whole or a portion of the application that is identified in the application control information using the digital broadcasting or the communication through the network as indicated in the signaling information after obtaining the application control information and the signaling information; and
executing the application after the application is acquired by the reception apparatus.

10. The reception method according to claim 9 , wherein
the signaling information includes information for acquiring another signaling information for another channel of the digital broadcasting when the application is to be acquired from the another channel of the digital broadcasting.

11. A transmission apparatus, comprising:
circuitry configured to
generate a stream to be transmitted in a channel of digital broadcasting using an IP (Internet Protocol) transmission method, the channel being identifiable by an IP address, and the stream including control information for triggering acquisition of an application;
generate signaling information for the channel, the signaling information indicating whether a whole or a portion of the application that is identified in application control information for the application is to be delivered using the digital broadcasting or communication through a network after transmission of the application control information and the signaling information;
transmit the signaling information and the stream in the channel of the digital broadcasting identifiable by the IP address using the IP transmission method; and
transmit the whole or the portion of the application using the digital broadcasting when the signaling information indicates that the whole or the portion of the application is to be delivered using the digital broadcasting.

12. The transmission apparatus according to claim 11 , wherein
the application is executed in conjunction with an AV content provided as a broadcasting service in the digital broadcasting.

13. The transmission apparatus according to claim 12 , wherein
the application is provided as a service same as or different from the broadcasting service.

14. The transmission apparatus according to claim 13 , wherein
the signaling information includes information for acquiring another signaling information for another channel of the digital broadcasting when the application is to be delivered using the another channel of the digital broadcasting.

15. The transmission apparatus according to claim 11 , wherein
the application is provided as an independent broadcasting service in the digital broadcasting.

16. The transmission apparatus according to claim 11 , wherein
the application includes entry point information and one or more resources, and
the entry point information includes location information of the one or more resources.

17. The transmission apparatus according to claim 16 , wherein
the signaling information includes an URL (Uniform Resource Locator) of the entry point information.

18. The transmission apparatus according to claim 11 , wherein the circuitry is further configured to
transmit the whole or the portion of the application using the channel of the digital broadcasting.

19. A transmission method for a transmission apparatus, comprising:
generating, by circuitry of the transmission apparatus, a stream to be transmitted in a channel of digital broadcasting using an IP (Internet Protocol) transmission method, the channel being identifiable by an IP address, and the stream including control information for triggering acquisition of an application;
generating, by the circuitry of the transmission apparatus, signaling information for the channel, the signaling information indicating whether a whole or a portion of the application that is identified in application control information for the application is to be delivered using the digital broadcasting or communication thr
