FIELD: information systems.
SUBSTANCE: invention refers to video coders using adaptive weighing of master images. The video decoder for decoding data from video signal for the image, having multiple motion boxes, containing: the master image weighting coefficient module for accepting, at least, one master image index, thereat each one from the mentioned master image indexes is intended for independent indication not using any other indexes, one of the multiple master images, used for prediction of current motion box and weighting coefficient from the set of weighting coefficients for current mentioned one from mentioned multiple motion boxes.
EFFECT: increase of efficiency in predicting master images.
