Abstract
The simultaneous transmission and reproduction of a compressed audio signal and a linear PCM signal is satisfactorily achieved. An audio signal of a predetermined unit is sequentially transmitted via a predetermined transmission line to a reception side. The audio signal of the predetermined unit is a mixed signal of a compressed audio signal and a linear PCM signal. For example, the audio signal of the predetermined unit is an audio signal of a sub-frame unit. In this case, for example, in the audio signal of the sub-frame unit, 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.
Claims18
