Abstract

A receiving apparatus includes: a reception portion configured to receive audio-visual content being transmitted; a trigger extraction portion configured to extract trigger information for controlling an application program for execution either by the receiving apparatus proper or by an external device connected thereto in conjunction with the audio-visual content, the application program being transmitted along with the audio-visual content; an apparatus proper control portion configured such that if a command indicated by the extracted trigger information is destined for the receiving apparatus proper, the apparatus proper control portion controls performance of the application program in accordance with the command; and an external device processing portion configured such that if the command indicated by the extracted trigger information is destined for the external device, the external device processing portion transfers the command to the external device.

Claims

1. A receiving apparatus comprising:

means for receiving audio-visual content being transmitted;

means for extracting trigger information for controlling a downloaded application program for execution either by said receiving apparatus or by an external device connected thereto in conjunction with said audio-visual content;

means for determining a destination of a command, which is indicated by the extracted trigger information, based on a destination attribute associated with the command;

means for controlling performance of said downloaded application program in accordance with said command when the destination is determined to be said receiving apparatus; and

means for transferring said command to said external device when the destination is determined to be said external device, wherein said external device controls performance of said downloaded application program in accordance with said command.

2. A receiving apparatus comprising:

circuitry to

receive audio-visual content being transmitted,

extract trigger information for controlling a downloaded application program for execution either by said receiving apparatus or by an external device connected thereto in conjunction with said audio-visual content,

determine a destination of a command, which is indicated by the extracted trigger information, based on a destination attribute associated with the command,

when the destination is determined to be said receiving apparatus, control performance of said downloaded application program in accordance with said command, and

when the destination is determined to be said external device, transfer said command to said external device, wherein said external device controls performance of said downloaded application program in accordance with said command.

3. The receiving apparatus according to claim 2, wherein, when said application program executed by said external device is different from the application program currently executed by said receiving apparatus, said circuitry allows said receiving apparatus to continue executing the currently executing application program.

4. The receiving apparatus according to claim 2, wherein said circuitry exercises control so that said receiving apparatus does not execute the same program as said application program currently executed by said external device.

5. The receiving apparatus according to claim 2, wherein said command indicated by said trigger information includes destination information for designating a specific device or part of or all of the devices that may be targeted by said command.

6. The receiving apparatus according to claim 2, wherein said trigger information includes one of the commands to acquire, register, start, fire an event in, suspend, and terminate a predetermined application program.

7. The receiving apparatus according to claim 6, wherein, in accordance with each of the commands, said circuitry exercises control so as to acquire, register, or start said application program;

or to fire an event in, suspend, or terminate the currently executing application program.

8. The receiving apparatus according to claim 6, wherein said circuitry transfers to said external device the command to acquire, register, or start said application program;

or to fire an event in, suspend, or terminate the currently executing application program.

11. The receiving apparatus according to claim 2, wherein, when said application program executed by said external device is the same as the application program currently executed by said receiving apparatus, said circuitry terminates said application program currently executed by said receiving apparatus.

12. The receiving apparatus according to claim 2, wherein the circuitry

determines whether the command indicated by the extracted trigger information is destined for said receiving apparatus or said external device based on the determined destination,

when the command indicated by the extracted trigger information is determined to be destined for said receiving apparatus, controls performance of said application program in accordance with said command, and

when the command indicated by the extracted trigger information is determined to be destined for said external device, transfers said command to said external device.

13. The receiving apparatus according to claim 2, wherein the circuitry receives a digital television broadcast signal including the audio-visual content.

14. The receiving apparatus according to claim 2, wherein said application program is transmitted along with said audio-visual content.

15. The receiving apparatus according to claim 2, wherein the circuitry receives the command and the destination attribute from an external source.

9. A receiving method for use with a receiving apparatus, said receiving method comprising:

causing circuitry of said receiving apparatus to receive audio-visual content being transmitted;

causing said circuitry of said receiving apparatus to extract trigger information for controlling a downloaded application program for execution either by said receiving apparatus or by an external device connected thereto in conjunction with said audio-visual content;

causing said circuitry of said receiving apparatus to determine a destination of a command, which is indicated by the extracted trigger information, based on a destination attribute associated with the command;

when the destination is determined to be said receiving apparatus, causing said receiving apparatus to control performance of said downloaded application program in accordance with said command; and

when the destination is determined to be said external device, causing said receiving apparatus to transfer said command to said external device, wherein said external device controls performance of said downloaded application program in accordance with said command.

10. A non-transitory computer-readable storage medium storing a program which when executed by a computer causes the computer to perform the method according to claim 9.
