ABSTRACT:
An audio data transmitting device with a varying channel count which on the transmission side includes, data of n channels divided into blocks each defined for m channels where n≦m. In addition, prior to a transmission of the audio data, a transmitted-data stream matching a predetermined transmission format is generated to include determination information used for determining which portions of each block is allocated to which portions of each block containing no valid data. On the reception side, the determination information included in the received transmitted-data stream matching the predetermined transmission format is used to identify the unused channels not assigned to valid data in each of the blocks composing the transmitted-data stream which allows data of the valid channels to be extracted from the stream.
