1. A reception method comprising:
a process of sequentially receiving an audio signal of a predetermined unit via a predetermined transmission line from a transmission side,
wherein the audio signal of the predetermined unit includes a mixed signal simultaneously received by mixing a compressed audio signal and a linear pulse code modulation (PCM) signal in each sub-frame of a plurality of sub-frames within at least one frame of the audio signal, and
wherein, following a preamble provided in each sub-frame, the compressed audio signal is arranged on an upper-order bit side, and the linear PCM signal is arranged on a lower-order bit side,
wherein identification information is added using a predetermined bit area of a channel status of each block that is configured for a predetermined number of the predetermined units, the identification information indicating that the audio signal of the predetermined unit includes the compressed audio signal and the linear PCM signal, and
wherein, in each sub-frame, the compressed audio signal is arranged on the upper-order bit side within 16 bits assigned to an area from a 12th bit to a 27th bit of the sub-frame and the linear PCM signal is arranged on the lower-order bit side within 8 bits assigned to an area from a 4th bit to an 11th bit of the sub-frame.
