Title:
チャネル間位相差パラメータ符号化方法および装置
Document Type and Number:
Japanese Patent JP7439152
Kind Code:
B2
Abstract:
This application discloses an inter-channel phase difference parameter encoding method, including: obtaining a reference parameter used to determine an inter-channel phase difference IPD parameter encoding scheme of a current frame of a multi-channel signal; determining the IPD parameter encoding scheme of the current frame based on the reference parameter, where the determined IPD parameter encoding scheme of the current frame is one of at least two preset IPD parameter encoding schemes; and processing an IPD parameter of the current frame based on the determined IPD parameter encoding scheme of the current frame. The technical solutions provided in this application can improve encoding quality of the multi-channel signal.
