PURPOSE: A decoding method of a coded video signal is provided to decode a set of video signals comprising a base layer signal and one enhancement layer signal, and to supply a decoded output signal with higher quality. CONSTITUTION: A decoding method for decoding a set of the video signals comprising a base layer signal(302) and at least one enhancement layer signal(304) and for supplying the decoded output signal includes a first decoding step(301) for decoding the base layer signal and supplying the decoded base layer signal, a second decoding step for decoding the enhancement layer signals and supplying the decoded enhancement layer signals, and a combining step for combining the decoded base layer signal and the decoded enhancement layer signals to supply the decoded output signal. The first decoding step is associated with a compensation step(305) for motion compensation of a reference image. The decoding method comprises a selection step for selecting, as a function of a selection signal, the signal from which the reference image is taken. The selection is made from the decoded base layer signal and the decoded output signal. |
