ENCODING METHOD, ENCODING DEVICE AND COMMUNICATION SYSTEM PROVIDED WITH THE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an encoding device which executes encoding which can constitute a decoding device corresponding to an apparatus exclusively used for two-channel reproducing at a low cost. SOLUTION: This encoding device 110 receives a multi-channel sound signal and outputs encoded transmission data. The encoding device 100 includes a down mix circuit 120, which receives a multi-channel sound signal of 5 channels to output a two-channel reproduced signal, and an encoding processing circuit 130 which encodes a part of the multi-channel sound signal and the two-channel reproduced signal and outputs transmission data Yadd.
