FIELD: physics.
SUBSTANCE: invention relates to means for receiving and transmitting audio data. Container of preset format having specified number of audio streams containing multiple elements of group encoded data is transmitted from transmission unit. Inserting into the container layer attribute information indicating an attribute for each of the plurality of group encoded data elements. At the data insertion step, addition information is additionally inserted into the container layer, corresponding to the flow indicating the audio stream containing each of the plurality of group encoded data elements, wherein the thread compliance information is information indicating the correspondence between the group identifier for identifying each of the plurality of group encoded data elements and the stream identifier for identifying each audio stream from the predetermined number of audio streams. Additionally, information on stream identifiers is inserted into a container layer, which indicates a stream identifier for each audio stream from a given number of audio streams.
EFFECT: technical result is higher efficiency of processing on receiving side when transmitting audio data of several types.
