Abstract

Claims (38)

1. A reproduction device comprising:

processing circuitry configured to:

receive a bit stream including encoded audio data and a plurality of pieces of zoom area information;

decode the encoded audio data;

select one or more pieces of zoom area information from among the plurality of pieces of zoom area information on the basis of information relating to the reproduction device; and

perform an audio converting process for the decoded audio data on the basis of the selected zoom area information,

wherein the audio data is an object-based audio, and

wherein the audio converting process includes moving a position of a sound source object.

2. The reproduction device according to claim 1 , wherein the received bit stream includes encoded video data and wherein the processing circuitry is further configured to:

decode the encoded video data; and

perform a trimming process for the decoded video data on the basis of the selected zoom area information.

3. The reproduction device according to claim 2 , wherein, in the plurality of pieces of zoom area information, the zoom area information designates an area for each specific video object is included.

4. The reproduction device according to claim 1 , wherein the information relating to the reproduction device indicates a type of the reproduction device.

5. The reproduction device according to claim 4 , wherein, in the plurality of pieces of zoom area information, the zoom area information designates an area for each type of reproduction target equipment is included.

6. The reproduction device according to claim 4 , wherein, in the plurality of pieces of zoom area information, the zoom area information designates an area for each rotation direction of reproduction target equipment is included.

7. The reproduction device according to claim 1 , wherein the processing circuitry is configured to select the zoom area information in accordance with a user's operation input.

8. The reproduction device according to claim 1 , wherein the processing circuitry is configured to select the zoom area information by using information representing a rotation direction of the reproduction device as the information relating to the reproduction device.

9. The reproduction device according to claim 1 , wherein the audio converting process includes changing a distance from the sound source object to a watching point.

10. A reproduction method executed by a reproduction device including processing circuitry, the reproduction method comprising:

receiving a bit stream including encoded audio data and a plurality of pieces of zoom area information;

decoding the encoded audio data;

selecting one or more pieces of zoom area information from among the plurality of pieces of zoom area information on the basis of information relating to the reproduction device; and

performing an audio converting process for the decoded audio data on the basis of the selected zoom area information,

wherein the audio data is an object-based audio, and

wherein the audio converting process includes moving a position of a sound source object.

11. The reproduction method according to claim 10 , wherein the received bit stream includes encoded video data, further comprising:

decoding the encoded video data; and

performing a trimming process for the decoded video data on the basis of the selected zoom area information.

12. A non-transitory computer readable medium containing instructions that, when executed by a reproduction device including processing circuitry, perform a reproduction method comprising:

receiving a bit stream including encoded audio data and a plurality of pieces of zoom area information;

decoding the encoded audio data;

selecting one or more pieces of zoom area information from among the plurality of pieces of zoom area information on the basis of information relating to the reproduction device; and

performing an audio converting process for the decoded audio data on the basis of the selected zoom area information,

wherein the audio data is an object-based audio, and

wherein the audio converting process includes moving a position of a sound source object.

13. The non-transitory computer readable medium according to claim 12 , wherein the received bit stream includes encoded video data and wherein the reproduction method further comprises:

decoding the encoded video data; and

performing a trimming process for the decoded video data on the basis of the selected zoom area information.
