Low coding delay alternating coding predictive and coding by transformed

摘要

The present invention relates to a method of coding of a digital signal, comprising the steps of coding (e601) of a preceding frame of samples of the digital signal in a predictive coding, of encoding (e603) of a current frame of samples of the digital signal according to a coding by transform. The method is such that a first part of the current frame is also encoded (e602) by a predictive coding restricted with respect to the predictive coding of the preceding frame. The present invention also relates to a corresponding decoding method of the method of coding described. It relates to an encoder and decoder using the methods of encoding and decoding described.
