FIELD: information technology.
SUBSTANCE: scalable video signal encoder includes an encoder for encoding a block in an enhancement layer of a picture by applying a same weighting parametre to an enhancement layer reference picture as that applied to a lower layer reference picture used for encoding a block in a lower layer of the picture. The block in the enhancement layer corresponds to the block in the lower layer, and the enhancement layer reference picture corresponds to the lower layer reference picture.
EFFECT: high efficiency of weighted prediction for scalable coding and decoding a video signal with possibility of storing different sets of weighting parametres for the same reference picture in the enhancement layer.
