Abstract

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.

Claims

1. A receiving device comprising:

a receiver that receives AV content;

a detector that detects trigger information that is transmitted together with the AV content to be received and relates to control of an application program for being run in conjunction with the AV content;

an acquirer that acquires an 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;

a tentative reservation registering part that registers AV content selected based on the acquired application program as tentative reservation; and

a definitive reservation registering part that registers the tentatively reserved AV content as definitive reservation if an identifier of 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 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 tentative reservation registering part registers selected AV content as tentative reservation if the download information is not recorded.

3. The receiving device according to claim 2, wherein

the application program is content for allowing 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, further comprising

a controller that controls acquisition or activation of the application program or stop 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 for being run in conjunction with the AV content;

acquiring an 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 AV content selected based on the acquired application program as tentative reservation; and

registering the tentatively reserved AV content as definitive reservation if an identifier of 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 AV content transmitted in non-real time, is identical to an identifier of the tentatively reserved AV content.

6. 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 for being run in conjunction with the AV content;

acquiring an 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 AV content selected based on the acquired application program as tentative reservation; and

registering the tentatively reserved AV content as definitive reservation if an identifier of 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 AV content transmitted in non-real time, is identical to an identifier of the tentatively reserved AV content.

7. A transmitting device comprising:

a trigger information generator that generates trigger information relating to control of an application program run in conjunction with AV content in a receiving device;

a transmitter that transmits the generated trigger information together with the AV content; and

a download information generator that generates download information relating to download of the AV content transmitted in non-real time,

wherein

the transmitter 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 an application program for allowing selection of AV content for which download reservation is possible and that is transmitted in non-real time or stop 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 transmitter 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 transmitter stores the trigger information in an adaptation field of a packet configuring 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 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 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 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.
