Abstract

A method, non-transitory computer-readable storage medium, and reception apparatus for processing one or more triggers associated with audio/video (A/V) content, and an information providing apparatus for providing the one or more triggers. The method includes receiving by the reception apparatus the A/V content and a first trigger associated with the received A/V content. Further, the reception apparatus retrieves a trigger parameters table (TPT), associated with the A/V content, from a TPT server identified in the received first trigger. The TPT defines at least one event associated with the A/V content and defines, for each of the at least one event, a parameter used to perform a process and corresponding to the respective event.

Claims

1. A method of a reception apparatus for processing one or more triggers associated with audio/video (A/V) content, the method comprising:

receiving by the reception apparatus the A/V content;

receiving a first trigger associated with the received A/V content; and

retrieving by the reception apparatus a trigger parameters table (TPT), associated with the A/V content, from a TPT server identified in the received first trigger, the TPT defining at least one event associated with the A/V content and defining, for each of the at least one event, a parameter used to perform a process and corresponding to the respective event.

2. The method according to claim 1, wherein the first trigger includes a current media time of the received A/V content, and the method further comprises:

determining an elapsed media time of the received A/V content based on the current media time included in the first trigger.

3. The method according to claim 2, wherein the first trigger includes a location of the TPT server, a location of the TPT in the TPT server, and the current media time.

4. The method according to claim 1, further comprising:

receiving a second trigger associated with the received A/V content and identifying an event defined in the TPT; and

performing the process using the parameter corresponding to the event defined in the second trigger when the reception apparatus receives the second trigger.

5. The method according to claim 4, wherein

the second trigger includes a location of the TPT server, a location of the TPT in the TPT server, and an identifier of the event defined in the TPT.

6. The method according to claim 1, further comprising:

receiving a second trigger associated with the received A/V content and identifying an event defined in the TPT and an event time, the event time identifying a future time of the identified event defined in the TPT; and

scheduling performance of the process using the parameter corresponding to the event identified in the second trigger to occur when an elapsed media time of the AN content equals the event time defined in the second trigger.

7. The method according to claim 6, wherein

the second trigger includes a location of the TPT server, a location of the TPT in the TPT server, an identifier of the event defined in the TPT, and the event time.

8. The method according to claim 1, further comprising:

receiving a second trigger including one or a combination of a location of the TPT server, a location of the TPT in the TPT server, a current media time, an identifier of an event defined in the TPT, an event time identifying a future time of a specified event defined in the TPT, and diffusion timing information.

9. The method according to claim 1, wherein

each trigger received by the reception apparatus includes a universal resource locator (URL) of the TPT server and one or a combination of a current media time, a trigger event id identifying an event defined in the TPT, an event time identifying a future time of a specified event defined in the TPT, and diffusion timing information.

10. A non-transitory computer-readable storage medium storing a program which when executed by a computer causes the computer to perform a method of a reception apparatus for processing one or more triggers associated with audio/video (A/V) content, the method comprising:

receiving by the reception apparatus the A/V content;

receiving a first trigger associated with the received A/V content; and

retrieving by the reception apparatus a trigger parameters table (TPT), associated with the A/V content, from a TPT server identified in the received first trigger, the TPT defining at least one event associated with the A/V content and defining, for each of the at least one event, a parameter used to perform a process and corresponding to the respective event.

11. A reception apparatus, comprising:

a first receiver configured to receive audio/video (A/V) content;

a second receiver configured to receive a first trigger associated with the received A/V content; and

a processor configured to retrieve a trigger parameters table (TPT), associated with the A/V content, from a TPT server identified in the received first trigger, the TPT defining at least one event associated with the A/V content and defining, for each of the at least one event, a parameter used to perform a process and corresponding to the respective event.

12. The reception apparatus according to claim 11, wherein

the first trigger includes a current media time of the received A/V content, and

the processor is configured to determine an elapsed media time of the received A/V content based on the current media time included in the first trigger.

13. The reception apparatus according to claim 12, wherein the first trigger includes a location of the TPT server, a location of the TPT in the TPT server, and the current media time.

the processor is configured to schedule performance of the process using the parameter corresponding to the event identified in the second trigger to occur when an elapsed media time of the A/V content equals the event time defined in the second trigger.

17. The reception apparatus according to claim 16, wherein
