Abstract  Abstract

The invention encodes a digital signal comprising encoding (E601) a previous frame of samples of the digital signal according to a predictive coding process, and encoding (E603) a current frame of samples of the digital signal according to a transform encoding process. It relates to a method for doing so. The method further limits the prediction encoding of the previous frame by reusing at least one parameter of the prediction encoding of the previous frame and encoding only the parameters of the first portion of the current frame that have not been reused. Is implemented to be encoded (E602) by the predictive encoding. The invention also relates to a decoding method corresponding to the described encoding method. The present invention further relates to an encoder and a decoder which respectively implement the encoding and decoding methods described above.
