Title:
ENCODING DEVICE AND ENCODING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/009082
Kind Code:
A1
Abstract:
This encoding device is able to encode an S signal efficiently in MS prediction encoding. An M signal encoding unit (106) generates first encoding information by encoding a sum signal indicating a sum of a left channel signal and a right channel signal that constitute a stereo signal. An energy difference calculation unit (101) calculates a prediction parameter for predicting a difference signal indicating a difference between the left channel signal and the right channel signal by using a parameter regarding an energy difference between the left channel signal and the right channel signal. An entropy encoding unit (103) generates second encoding information by encoding the prediction parameter.
