Abstract

A method, computer program, and reception apparatus, and information providing apparatus. The method includes receiving a trigger parameters table (TPT). The TPT is associated with a triggered declarative object (TDO) and includes at least one parameter associated with a trigger event. The TPT is stored in a first memory of the reception apparatus. The TDO is executed by a processor of the reception apparatus and is stored in a second memory of the reception apparatus. The reception apparatus receives a trigger associated with the trigger event. At least one parameter associated with the trigger event is retrieved from the TPT based on information included in the trigger. Further, a function is performed based on the retrieved at least one parameter.

Claims

1. A method of a reception apparatus for processing triggers, comprising:

receiving a trigger parameters table (TPT), the TPT being associated with a triggered declarative object (TDO) and including at least one parameter associated with a trigger event;

storing the TPT in a first memory of the reception apparatus;

executing, by a processor of the reception apparatus, the TDO stored in a second memory of the reception apparatus;

receiving a trigger associated with the trigger event;

retrieving the at least one parameter associated with the trigger event from the TPT based on information included in the trigger; and

performing a function based on the retrieved at least one parameter.

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

receiving content via at least one of a satellite broadcast, a cable television transmission, a terrestrial television broadcast, and the Internet, the content being associated with the TDO; and

displaying the received content on a display.

3. The method according to claim 1, wherein the step of receiving the TPT comprises:

receiving the TPT via a satellite broadcast, a cable television transmission, a terrestrial television broadcast, or the Internet.

4. The method according to claim 1, wherein the step of receiving the trigger comprises:

receiving the trigger associated with the trigger event via a satellite broadcast, a cable television transmission, a terrestrial television broadcast, or the Internet.

5. The method according to claim 1, wherein the step of executing comprises:

executing, by the processor of the reception apparatus, a DO Engine that executes the TDO stored in the second memory of the reception apparatus.

6. The method according to claim 5, further comprising:

extracting, by the DO Engine, the information from the received trigger; and

providing, by the DO Engine, the extracted information to the TDO, wherein

the information included in the trigger is a tag value.

7. The method according to claim 5, wherein the TPT does not include tag values reserved for commands executed by the DO Engine.

8. The method according to claim 1, wherein

the information included in the trigger is a tag value;

and

the TPT identifies an image associated with the tag value.

9. The method according to claim 1, wherein the information included in the trigger includes a TDO identifier and a tag value.

10. The method according to claim 1, wherein the information included in the trigger is a media time.

11. A non-transitory computer-readable storage medium having embedded therein instructions, which when executed by a computer, causes the computer to perform a method of a reception apparatus for processing triggers, the method comprising:

receiving a trigger parameters table (TPT), the TPT being associated with a triggered declarative object (TDO) and including at least one parameter associated with a trigger event;

storing the TPT in a first memory of the reception apparatus;

executing, by the computer, the TDO stored in a second memory of the reception apparatus;

receiving a trigger associated with the trigger event;

retrieving the at least one parameter associated with the trigger event from the TPT based on information included in the trigger; and

performing a function based on the retrieved at least one parameter.

12. A reception apparatus, comprising:

a first communication unit configured to receive a trigger parameters table (TPT), the TPT being associated with a triggered declarative object (TDO) and including at least one parameter associated with a trigger event;

a first memory configured to store the TPT;

a second memory configured to store the TDO;

a processor configured to execute the TDO stored in the second memory; and

a second communication unit configured to receive a trigger associated with the trigger event, wherein

when the second communication unit receives the trigger, the processor retrieves the at least one parameter associated with the trigger event from the TPT based on information included in the trigger and performs a function based on the retrieved at least one parameter.

13. The reception apparatus according to claim 12, further comprising:

a receiver configured to receive content via at least one of a satellite broadcast, a cable television transmission, a terrestrial television broadcast, and the Internet, the content being associated with the TDO; and

a display interface configured to display the received content.

14. The reception apparatus according to claim 12, wherein the first communication unit is configured to receive the TPT via a satellite broadcast, a cable television transmission, a terrestrial television broadcast, or the Internet.

15. The reception apparatus according to claim 12, wherein the second communication unit is configured to receive the trigger associated with the trigger event via a satellite broadcast, a cable television transmission, a terrestrial television broadcast, or the Internet.

16. The reception apparatus according to claim 12, wherein the processor is configured to execute a DO Engine that executes the TDO stored in the second memory.

17. The reception apparatus according to claim 16, wherein

the information included in the trigger is a tag value;

and

the TPT identifies an image associated with the tag value.

20. The reception apparatus according to claim 12, wherein the information included in the trigger includes a TDO identifier and a tag value.

21. The reception apparatus according to claim 12, wherein the information included in the trigger is a media time.

22. An information providing apparatus, comprising:

a memory configured to store a trigger parameters table (TPT), the TPT being associated with a triggered declarative object (TDO) and including at least one parameter associated with a trigger event; and

a communication unit configured to provide the TPT to a reception apparatus.
