13. A reception method comprising:
receiving, by reception circuitry of a reception device, a container, the container including a plurality of audio streams for carrying a plurality of groups of encoded data and a configuration descriptor,
each audio stream of the plurality of audio streams including one or more groups from the plurality of groups of encoded data, and
the configuration descriptor including a plurality of pieces of group information, each piece of the pieces of group information being processed in a for loop and indicating a correspondence between a corresponding group of encoded data from the groups of encoded data and an audio stream of the plurality of audio streams that includes the corresponding group, by including
(i) a group identifier identifying the corresponding group of encoded data from the plurality of groups of encoded data,
(ii) an audio stream identifier identifying the audio stream of the plurality of audio streams in which the corresponding group of encoded data is included, and
(iii) an audio sub-stream identifier;
acquiring, by processing circuitry of the reception device, a collection of groups of encoded data on the basis of the configuration descriptor from the plurality of audio streams included in the received container;
generating, by the processing circuitry, an output audio stream including the collection of groups of encoded data; and
transmitting, by transmission circuitry of the reception device, the generated output audio stream to an external device.
