Reception apparatus, transmission apparatus, and data processing method
The present technology relates to a reception apparatus, a transmission apparatus, and a data processing method that permit downloaded reproduction of non-realtime content by reducing load associated with implementing resident applications. The reception apparatus acquires a first application, included in a digital broadcast signal, that handles a download of content reproduced in non-realtime, acquires metadata, included in the digital broadcast signal, that includes information for controlling the content download in response to operation of the first application, and handles the download of the content included in the digital broadcast signal by controlling the operation of the first application on the basis of the metadata. The present technology is applicable, for example, to a TV receiver.
1. A reception apparatus comprising:
receiver circuitry configured to receive a digital broadcast signal; and
processing circuitry configured to:
acquire a first application that handles a download of content reproduced in non-realtime, the first application included in the digital broadcast signal,
acquire metadata that includes information for controlling the content download in response to operation of the first application, the metadata included in the digital broadcast signal, and
control acquisition of the content reproduced in non-realtime by controlling the operation of the first application on the basis of the metadata, the content reproduced in non-realtime included in the digital broadcast signal.
2. The reception apparatus of claim 1 , wherein
the metadata includes at least
first information associated with the content,
second information associated with a second application that processes the content.
3. The reception apparatus of claim 2 , wherein
the second information includes information associated with the second application which is configured to refer to the content.
4. The reception apparatus of claim 2 , wherein
the first information includes path information which specifies a path where the content is delivered.
5. The reception apparatus of claim 4 , wherein
the path information specifies a Real-Time Object Delivery over Unidirectional Transport (ROUTE) session where the content is delivered.
6. The reception apparatus of claim 2 , wherein
the first application is acquired in response to first control information for controlling the first application, and
the second application is acquired in response to second control information for controlling the second application.
7. The reception apparatus of claim 2 , wherein
the first application is acquired in response to reservation operation of a third application that reserves the content.
8. The reception apparatus of claim 7 , wherein
the second application can perform the reservation operation.
9. The reception apparatus of claim 7 , wherein
the first application, the second application, and the third application are applications developed using a given markup language.
10. A data processing method of a reception apparatus, the data processing method comprising the steps of:
the reception apparatus receiving a digital broadcast signal;
the reception apparatus acquiring a first application that handles a download of content reproduced in non-realtime, the first application included in the digital broadcast signal;
the reception apparatus acquiring metadata that includes information for controlling the content download in response to operation of the first application, the metadata included in the digital broadcast signal; and
the reception apparatus controlling the acquisition of the content reproduced in non-realtime by controlling the operation of the first application on the basis of the metadata, the content reproduced in non-realtime included in the digital broadcast signal.
11. A transmission apparatus comprising:
processing circuitry configured to:
generate metadata that includes information for controlling a download of content reproduced in non-realtime,
generate a first application that handles the content download, and
send the metadata and the first application included in a digital broadcast signal.
12. The transmission apparatus of claim 11 , wherein
the metadata includes at least
first information associated with the content,
second information associated with a second application that processes the content.
13. The transmission apparatus of claim 12 , wherein
the second information includes information associated with the second application which is configured to refer to the content.
14. The transmission apparatus of claim 13 , wherein
the processing circuitry sends a third application that reserves the content.
15. The transmission apparatus of claim 14 , wherein
the first application, the second application, and the third application are applications developed using a given markup language.
16. The transmission apparatus of claim 12 , wherein
the first information includes path information which specifies a path where the content is delivered.
17. The transmission apparatus of claim 12 , wherein
the processing circuitry sends first control information for controlling operation of the first application and second control information for controlling operation of the second application.
18. A data processing method of a transmission apparatus, the data processing method comprising the steps of:
the transmission apparatus generating metadata that includes information for controlling a download of content to be reproduced in non-realtime;
the transmission apparatus generating a first application that handles the content download; and
the transmission apparatus sending the metadata and the first application included in a digital broadcast signal.
