Receiving device and method, transmitting device and method, and program
View Patent ↗The present disclosure provides a receiving device including, a receiver that receives AV content, a detector, an acquirer, a tentative reservation registering part, and a definitive reservation registering part.
1. A receiving device comprising:
circuitry configured to
receive AV content;
detect trigger information that is transmitted together with the AV content to be received and relates to control of an application program to be run in conjunction with the AV content;
acquire the application program for allowing selection of AV content for which download reservation is possible and that is transmitted in non-real time, based on the detected trigger information;
register the AV content selected based on the acquired application program as a tentative reservation; and
register the tentatively reserved AV content as a definitive reservation when an identifier of the AV content for which download reservation is possible, included in download information that is periodically transmitted together with the AV content and relates to download of the AV content transmitted in non-real time, is identical to an identifier of the tentatively reserved AV content.
2. The receiving device according to claim 1 , wherein
the circuitry is configured to register the selected AV content as a tentative reservation when the download information is not recorded.
3. The receiving device according to claim 2 , wherein
the application program provides an interface for allowing the selection of AV content for which download reservation is possible and that is transmitted in non-real time based on a list.
4. The receiving device according to claim 3 , wherein
the circuitry is configured to control acquisition or activation of the application program or termination of the application program that is running, in accordance with a command indicated by the detected trigger information.
5. A receiving method of a receiving device that receives AV content, the method comprising:
receiving the AV content;
detecting trigger information that is transmitted together with the AV content to be received and relates to control of an application program to be run in conjunction with the AV content;
acquiring the application program for allowing selection of AV content for which download reservation is possible and that is transmitted in non-real time, based on the detected trigger information;
registering, by a processor of the receiving device, the AV content selected based on the acquired application program as a tentative reservation; and
registering, by the processor of the receiving device, the tentatively reserved AV content as a definitive reservation when an identifier of the AV content for which download reservation is possible, included in download information that is periodically transmitted together with the AV content and relates to download of the AV content transmitted in non-real time, is identical to an identifier of the tentatively reserved AV content.
6. A non-transitory computer-readable storage medium storing a program for control of a receiving device that receives AV content, the program causing a computer to execute processing comprising:
receiving the AV content;
detecting trigger information that is transmitted together with the AV content to be received and relates to control of an application program to be run in conjunction with the AV content;
acquiring the application program for allowing selection of AV content for which download reservation is possible and that is transmitted in non-real time, based on the detected trigger information;
registering, by the computer, the AV content selected based on the acquired application program as a tentative reservation; and
registering the tentatively reserved AV content as a definitive reservation when an identifier of the AV content for which download reservation is possible, included in download information that is periodically transmitted together with the AV content and relates to download of the AV content transmitted in non-real time, is identical to an identifier of the tentatively reserved AV content.
7. A transmitting device comprising:
circuitry configured to
generate trigger information relating to control of an application program run in conjunction with AV content in a receiving device;
transmit the generated trigger information together with the AV content; and
generate download information relating to download of the AV content transmitted in non-real time, wherein
the circuitry periodically transmits the generated download information together with the AV content.
8. The transmitting device according to claim 7 , wherein
at least one of commands to control acquisition or activation of the application program for allowing selection of AV content for which download reservation is possible and that is transmitted in non-real time or termination of the application program that is running is included in a command indicated by the trigger information.
9. The transmitting device according to claim 7 , wherein
the circuitry multiplexes the trigger information into a transport stream corresponding to the AV content and transmits the trigger information.
10. The transmitting device according to claim 7 , wherein
the circuitry stores the trigger information in an adaptation field of a packet in a transport stream corresponding to the AV content and transmits the trigger information.
11. A transmitting method of a transmitting device that transmits AV content, the method comprising:
generating, trigger information relating to control of an application program run in conjunction with the AV content in a receiving device;
transmitting the generated trigger information together with the AV content; and
generating, by a processor of the transmitting device, download information relating to download of the AV content transmitted in non-real time, wherein
the generated download information is periodically transmitted together with the AV content by processing of the transmitting step.
12. A non-transitory computer-readable storage medium storing a program for control of a transmitting device that transmits AV content, the program causing a computer to execute processing comprising:
generating trigger information relating to control of an application program run in conjunction with the AV content in a receiving device;
transmitting the generated trigger information together with the AV content; and
generating, by the computer, download information relating to download of the AV content transmitted in non-real time, wherein
the generated download information is periodically transmitted together with the AV content by processing of the transmitting step.
13. The receiving device according to claim 1 , wherein
the circuitry is configured to receive a digital television broadcast signal including the AV content and the identifier of the AV content for which download reservation is possible.
14. The transmitting device according to claim 7 , wherein
the application program is configured to allow by the receiving device selection of the AV content transmitted in non-real time for which download reservation is possible; and
when a selected one of the AV content transmitted in non-real time is registered as a tentative reservation, the tentative reservation is registered as a definitive registration when the download information includes an identifier of the selected one of the AV content transmitted in non-real time that is registered as the tentative reservation.
