FIELD: information technologies.
SUBSTANCE: parametres of coding, such as tables of end of block (EOB) shift and selection of dictionary of VLC-coding may be stored as internal conditions instead of their sending with coded data of series of serial macroblocks of video. Records of tables may periodically be updated on the basis of statistics collected in process of coding stage. Table of special EOB shift may adapt position of symbol of special EOB in set of symbols to probability of significant coefficients with absolute value, more than 1, for condition of coding, such as cycle of coding. Units of colour signal may be coded independently on blocks of brightness signal with the help of separate table of EOB shift tables, shift of special EOB and selection of VLC-coding dictionary.
EFFECT: increased efficiency of adaptive coding with alternating length.
