Title: CODING DEVICE AND CODING METHOD
Abstract:
An interchannel correlation calculation unit (102) calculates an interchannel correlation between a left channel and a right channel using a left channel signal and a right channel signal that constitute a stereo signal. A DMA stereo coding unit (104) and a DM stereo coding unit (105) code the left channel signal and the right channel signal, respectively, using a common coding mode if the interchannel correlation is greater than a threshold value, and code the left channel signal and the right channel signal, respectively, using coding modes determined individually for the left channel signal and the right channel signal if the interchannel correlation is equal to or smaller than the threshold value.
