FIELD: information technology.
SUBSTANCE: each nonzero coefficient of the enhancing layer coefficient vector is encoded without knowing any other subsequent coefficients. Encoding the enhancing layer in a single pass can avoid the need to perform a first pass for analysing the coefficient vector and a second pass for encoding the coefficient vector based on the analysis.
EFFECT: providing statistical encoding of the bit stream of an enhancing layer in one encoding pass, thereby simplifying encoding, reducing encoding delay and memory requirements.
