Reception apparatus, transmission apparatus, and data processing method
The present technique relates to a reception apparatus, a transmission apparatus, and a data processing method that enable to execute a process according to delivery of resource files of an application associated with content. The reception apparatus receives content, acquires resource delivery information regarding delivery of one or a plurality of resource files that are part of an application associated with the content, the resource delivery information transmitted along with the content, and executes a process according to the delivery of the resource files on a basis of the acquired resource delivery information. The present technique can be applied to, for example, a television receiver that can receive digital broadcasting.

execute a process according to the delivery of the resource files on a basis of the acquired resource delivery information, wherein
video and audio data of the content is transmitted in a Real-time Object Delivery over Unidirectional Transport (ROUTE) session that is a protocol for transferring a streaming file, and
the resource delivery information is included in an Extended File Delivery Table (EFDT) transmitted in the ROUTE session, the EFDT specified by Service-based Transport Session Instance Description (S-TSID) that is control information of a ROUTE protocol.
2. The reception apparatus according to claim 1 , wherein
the resource delivery information includes delivery schedule information regarding a delivery schedule of each of the resource files.
3. The reception apparatus according to claim 2 , wherein
the delivery schedule information includes information regarding at least one of a size and delivery time of each of the resource files.
4. The reception apparatus according to claim 1 , wherein
the resource delivery information includes transfer control information regarding delivery of a specific resource file with a delivery schedule that has possibilities to be changed according to a time zone.
5. The reception apparatus according to claim 4 , wherein
the transfer control information includes information regarding at least one of a retransmission cycle and retransmission end time of the specific resource file.
6. The reception apparatus according to claim 2 , wherein
the delivery schedule information is included in an application manifest file packaged together with a startup package file transmitted in the ROUTE session.
7. A data processing method of a reception apparatus executed by the reception apparatus, the data processing method comprising:
acquiring resource delivery information regarding delivery of one or more resource files that are related to an application associated with content, wherein the resource delivery information includes a location of each resource file of the one or more resource files that are related to an application associated with the content; and
executing a process according to the delivery of the resource files on a basis of the acquired resource delivery information, wherein
video and audio data of the content is transmitted in a Real-time Object Delivery over Unidirectional Transport (ROUTE) session that is a protocol for transferring a streaming file, and
the resource delivery information is included in an Extended File Delivery Table (EFDT) transmitted in the ROUTE session, the EFDT specified by Service-based Transport Session Instance Description (S-TSID) that is control information of a ROUTE protocol.
8. The data processing method according to claim 7 , wherein
the resource delivery information includes delivery schedule information regarding a delivery schedule of each of the resource files.
9. The data processing method according to claim 8 , wherein
the delivery schedule information includes information regarding at least one of a size and delivery time of each of the resource files.
10. The data processing method according to claim 7 , wherein
the resource delivery information includes transfer control information regarding delivery of a specific resource file with a delivery schedule that has possibilities to be changed according to a time zone.
11. The data processing method according to claim 10 , wherein
the transfer control information includes information regarding at least one of a retransmission cycle and retransmission end time of the specific resource file.
12. The data processing method according to claim 8 , wherein
the delivery schedule information is included in an application manifest file packaged together with a startup package file transmitted in the ROUTE (Real-time Object Delivery over Unidirectional Transport) session.
13. A transmission apparatus comprising:
processing circuitry configured to
generate resource delivery information regarding delivery of one or more resource files that are related to an application associated with content, wherein the resource delivery information includes a location of each resource file of the one or more resource files that are related to the application associated with the content; and
transmit the resource delivery information, wherein
video and audio data of the content is transmitted in a Real-time Object Delivery over Unidirectional Transport (ROUTE) session that is a protocol for transferring a streaming file, and
the resource delivery information is transmitted in an Extended File Delivery Table (EFDT) transmitted in the ROUTE session, the EFDT specified by Service-based Transport Session Instance Description (S-TSID) that is control information of a ROUTE protocol.
14. The transmission apparatus according to claim 13 , wherein
the resource delivery information includes delivery schedule information regarding a delivery schedule of each of the resource files.
15. The transmission apparatus according to claim 14 , wherein
the delivery schedule information includes information regarding at least one of a size and delivery time of each of the resource files.
16. The transmission apparatus according to claim 13 , wherein
the resource delivery information includes transfer control information regarding delivery of a specific resource file with a delivery schedule that has possibilities to be changed according to a time zone.
17. The transmission apparatus according to claim 16 , wherein
the transfer control information includes information regarding at least one of a retransmission cycle and retransmission end time of the specific resource file.
18. The transmission apparatus according to claim 14 , wherein
the delivery schedule information is included in an application manifest file packaged together with a startup package file transmitted in the ROUTE session.
19. A data processing method of a transmission apparatus executed by the transmission apparatus, the data processing method comprising:
generating resource delivery information regarding delivery of one or more resource files that are related to an application associated with content, wherein the resource delivery information includes a location of each resource file of the one or more resource files that are related to the application associated with the content; and
transmitting the resource delivery information, wherein
video and audio data of the content is transmitted in a Real-time Object Delivery over Unidirectional Transport (ROUTE) session that is a protocol for transferring a streaming file, and
