FIELD: information technologies.
SUBSTANCE: video sequence is processed into combination of frames, besides each frame of multiple frames is processed into multiple macroblocks. Forecast of initial video signal, which is part of macroblock in current frame, is generated from video sequence. Differential signal is generated by subtraction of initial video signal forecast from original video signal in current frame. Conversion of initial signal is applied, besides multiple conversion ratios are quantised, symbol of at least one syntactic element, which determines characteristic of differential signal, is established. Symbols of at least one syntactic element of one and the same category are coded jointly.
EFFECT: increased efficiency of information coding and decoding.
