FIELD: data processing.
SUBSTANCE: invention relates to means for encoding an array of samples. Entropy coding of the current part of the predetermined entropy slice is based not only on the corresponding estimates of the probability of a predetermined entropy slice, that adapt using the previously encoded part of the predetermined entropy slice, but also on the probability estimates, that are used for entropy coding of spatially adjacent, orderly entropy slices of the previous entropy slice in its neighboring part. Thereby estimate of probability used for entropy coding are adapted to the actual statistical information of the symbol more approximate, thus reducing the reduction in coding efficiency, usually caused by lower delay concepts. Time correlations are used additionally or alternatively.
EFFECT: technical result is to reduce the delay in encoding the array of samples.
