Abstract
A processing load at a receiving side is reduced in a case where a plurality of classes of audio data is transmitted. A predetermined number of audio streams including coded data of a plurality of groups is generated and a container of a predetermined format having this predetermined number of audio streams is transmitted. Command information for creating a command specifying a group to be decoded from among the plurality of groups is inserted into the container and/or the audio stream. For example, a command insertion area for the receiving side to insert a command for specifying a group to be decoded is provided in at least one audio stream among the predetermined number of audio streams.
Claims18
An information processing apparatus, comprising:
- circuitry configured to
- receive a container of a predetermined format including a predetermined number of audio streams, wherein the audio streams include a preset group in which a plurality of the groups are grouped together, each group having a plurality of object coded data including a preset group ID that is an identifier identifying the preset group;
- integrate the predetermined number of audio streams and output an integrated audio stream;
- perform a process of obtaining audio data for driving a speaker system by performing a decoding process on the integrated audio stream;
- and
- process the obtained audio data, and output the processed audio data to the speaker system.
An information processing method, comprising:
- receiving a container of a predetermined format including a predetermined number of audio streams, wherein the audio streams include a preset group in which a plurality of the groups are grouped together, each group having a plurality of object coded data including a preset group ID that is an identifier identifying the preset group;
- integrating the predetermined number of audio streams and outputting an integrated audio stream;
- performing a process of obtaining audio data for driving a speaker system by performing a decoding process on the integrated audio stream;
- and
- processing the obtained audio data, and outputting the processed audio data to the speaker system.
A non-transitory computer-readable medium storing instructions that, when executed by circuitry, cause the circuitry to perform:
- receiving a container of a predetermined format including a predetermined number of audio streams, wherein the audio streams include a preset group in which a plurality of the groups are grouped together, each group having a plurality of object coded data including a preset group ID that is an identifier identifying the preset group;
- integrating the predetermined number of audio streams and outputting an integrated audio stream;
- performing a process of obtaining audio data for driving a speaker system by performing a decoding process on the integrated audio stream;
- and
- processing the obtained audio data, and outputting the processed audio data to the speaker system.
