Abstract

Disclosed herein is a receiving device including: a receiver that receives AV content; a trigger information acquirer that acquires trigger information adapted to identify control information to control operation of an application program run in conjunction with the AV content; a table acquirer that acquires a table in which the control information identified by the trigger information is stored in response to first version information that is included in the trigger information and indicates a version of the table; and a control section that controls the operation of the application program in response to the control information that is identified by the trigger information and is stored in the table.

Claims

1. A receiving device comprising:

a receiver that receives audio/video content;

a trigger information acquirer that acquires trigger information adapted to identify control information to control operation of an application program run in conjunction with the audio/video content;

a table acquirer that acquires a table in which the control information identified by the trigger information is stored in response to first version information that is included in the trigger information and indicates a version of the table; and

a control section that controls the operation of the application program in response to the control information that is identified by the trigger information and is stored in the table.

2. The receiving device according to claim 1,

wherein second version information indicating the version of the table is stored in the table, and

the table acquirer acquires the table if the first version information included in the trigger information is different from the second version information stored in the table.

3. The receiving device according to claim 2,

wherein the trigger information is transmitted by a broadcast together with the audio/video content,

the table is delivered via a network,

the trigger information acquirer extracts the trigger information from data of the audio/video content, and

the table acquirer acquires the table delivered via the network.

4. The receiving device according to claim 2,

wherein the audio/video content is transmitted by a broadcast,

the table is delivered via a network,

the receiving device further includes a feature extractor that extracts a feature from data of the audio/video content,

the trigger information acquirer acquires the trigger information corresponding to an identification result of the audio/video content identified by using the feature, and

the table acquirer acquires the table delivered via the network.

5. The receiving device according to claim 1,

wherein an action indicating the operation of the application program is associated with time at which the action should be executed in the table, and

the control section controls the operation of the application program in response to the action identified from the table based on time information included in the trigger information.

6. A receiving method of a receiving device, the method executed by the receiving device, comprising:

receiving audio/video content;

acquiring trigger information adapted to identify control information to control operation of an application program run in conjunction with the audio/video content;

acquiring a table in which the control information identified by the trigger information is stored in response to first version information that is included in the trigger information and indicates a version of the table; and

controlling the operation of the application program in response to the control information that is identified by the trigger information and is stored in the table.

7. A transmitting device comprising:

a trigger information generator that generates trigger information that is adapted to identify control information to control operation of an application program run in conjunction with audio/video content and includes version information indicating a version of a table in which the control information identified by the trigger information is stored; and

a transmitter that transmits the trigger information together with the audio/video content.

8. A transmitting method of a transmitting device, the method executed by the transmitting device, comprising:

generating trigger information that is adapted to identify control information to control operation of an application program run in conjunction with audio/video content and includes version information indicating a version of a table in which the control information identified by the trigger information is stored; and

transmitting the trigger information together with the audio/video content.
