Abstract
A processing load of a reception side is reduced when a plurality of types of audio data is transmitted. A predetermined format container is transmitted having a predetermined number of audio streams including a plurality of group encoded data. For example, the plurality of group encoded data includes either or both of channel encoded data and object encoded data. Attribute information indicating an attribute of each of the plurality of group encoded data is inserted into a layer of the container. For example, stream correspondence information indicating an audio stream including each of the plurality of group encoded data is further inserted into the layer of the container.
Claims18
A transmission device comprising:
- a transmission unit for transmitting a predetermined format container having a predetermined number of audio streams including a plurality of group encoded data;
- and
- an information insertion unit for inserting attribute information indicating an attribute of each of the plurality of group encoded data, into a layer of the container.
A transmission method comprising:
- a transmission step for transmitting a predetermined format container having a predetermined number of audio streams including a plurality of group encoded data, from a transmission unit;
- and
- an information insertion step for inserting attribute information indicating an attribute of each of the plurality of group encoded data, into a layer of the container.
A reception device comprising:
- a reception unit for receiving a predetermined format container having a predetermined number of audio streams including a plurality of group encoded data, attribute information indicating an attribute of each of the plurality of group encoded data being inserted into a layer of the container;
- and
- a processing unit for processing the predetermined number of audio streams included in the container received, on the basis of the attribute information.
A reception method comprising:
- a reception step for receiving a predetermined format container having a predetermined number of audio streams including a plurality of group encoded data, by a reception unit, attribute information indicating an attribute of each of the plurality of group encoded data being inserted into a layer of the container;
- and
- a processing step for processing the predetermined number of audio streams included in the container received, on the basis of the attribute information.
A reception device comprising:
- a reception unit for receiving a predetermined format container having a predetermined number of audio streams including a plurality of group encoded data, attribute information indicating an attribute of each of the plurality of group encoded data being inserted into a layer of the container;
- a processing unit for selectively acquiring predetermined group encoded data on the basis of the attribute information from the predetermined number of audio streams included in the container received, and reconfiguring an audio stream including the predetermined group encoded data;
- and
- a stream transmission unit for transmitting the audio stream reconfigured in the processing unit to an external device.
A reception method comprising:
- a reception step for receiving a predetermined format container having a predetermined number of audio streams including a plurality of group encoded data, by a reception unit, attribute information indicating an attribute of each of the plurality of group encoded data being inserted into a layer of the container;
- a processing step for selectively acquiring predetermined group encoded data on the basis of the attribute information from the predetermined number of audio streams included in the container received, and reconfiguring an audio stream including the predetermined group encoded data;
- and
- a stream transmission step for transmitting the audio stream reconfigured in the processing step to an external device.
