Abstract

Disclosed herein is a transmitting device including an audio encoder and a transmitter. The audio encoder is configured to generate an encoded audio stream in which trigger information relating to control of an application program to be executed in conjunction with content in a receiving device is buried. The transmitter is configured to transmit the generated encoded audio stream to the receiving device.

Claims

1. A transmitting device comprising:

an audio encoder configured to generate an encoded audio stream in which trigger information relating to control of an application program to be executed in conjunction with content in a receiving device is buried; and

a transmitter configured to transmit the generated encoded audio stream to the receiving device.

2. The transmitting device according to claim 1, further comprising:

a controller configured to supply metadata in which the trigger information is stored and size information for burying the metadata in a user data area of the encoded audio stream, and carry out control so that the metadata be buried in the user data area.

3. The transmitting device according to claim 2, wherein

the audio encoder encodes an audio stream by an audio code number 3 system to generate the encoded audio stream, and

the metadata is inserted in an area of auxiliary data in a frame structure of the audio code number 3 system.

4. The transmitting device according to claim 2, wherein

the audio encoder encodes an audio stream by an advanced audio coding system to generate the encoded audio stream, and

the metadata is inserted in an area of data stream element in a frame structure of the advanced audio coding system.

5. The transmitting device according to claim 1, further comprising:

a video encoder configured to encode a video stream to generate an encoded video stream; and

a multiplexer configured to multiplex the encoded audio stream and the encoded video stream to generate a multiplexed stream,

wherein the transmitter transmits the generated multiplexed stream.

6. The transmitting device according to claim 1, wherein

type information indicating a type of information is added to the metadata.

7. The transmitting device according to claim 1, wherein

a plurality of kinds of information distinguished by an information identifier are included in the metadata.

8. A transmitting method of a transmitting device that transmits content, the method comprising:

generating an encoded audio stream in which trigger information relating to control of an application program to be executed in conjunction with content in a receiving device is buried; and

transmitting the generated encoded audio stream to the receiving device.

9. A program for controlling a transmitting device that transmits content, the program causing a computer of the transmitting device to:

generate an encoded audio stream in which trigger information relating to control of an application program to be executed in conjunction with content in a receiving device is buried; and

transmit the generated encoded audio stream to the receiving device.

10. A receiving device comprising:

a receiver configured to receive an encoded audio stream in which trigger information relating to control of an application program to be executed in conjunction with content is buried, the encoded audio stream being transmitted from a transmitting device;

an audio decoder configured to decode the received encoded audio stream; and

a controller configured to control processing relating to the application program executed in conjunction with the content in response to the trigger information obtained by decoding the encoded audio stream.

11. The receiving device according to claim 10, wherein

the audio decoder acquires the trigger information stored in metadata from an area of auxiliary data in a frame structure of the encoded audio stream encoded by an audio code number 3 system.

12. The receiving device according to claim 10, wherein

the audio decoder acquires the trigger information stored in metadata from an area of data stream element in a frame structure of the encoded audio stream encoded by an advanced audio coding system.

13. The receiving device according to claim 10, further comprising:

a demultiplexer configured to demultiplex a received multiplexed stream; and

a video decoder configured to decode an encoded video stream demultiplexed from the multiplexed stream,

wherein the audio decoder decodes the encoded audio stream demultiplexed from the multiplexed stream.

14. A receiving method of a receiving device that receives content, the method comprising:

receiving an encoded audio stream in which trigger information relating to control of an application program to be executed in conjunction with content is buried, the encoded audio stream being transmitted from a transmitting device;

decoding the received encoded audio stream; and

controlling processing relating to the application program executed in conjunction with the content in response to the trigger information obtained by decoding the encoded audio stream.

15. A program for controlling a receiving device that receives content, the program causing a computer of the receiving device to:

receive an encoded audio stream in which trigger information relating to control of an application program to be executed in conjunction with content is buried, the encoded audio stream being transmitted from a transmitting device;

decode the received encoded audio stream; and
