FIELD: data processing.
SUBSTANCE: invention relates to means of samples array coding. Entropy coding of the current part of a predetermined entropy slice is based not only on corresponding estimates of probability of predetermined entropy slice, which adapt using previously encoded part of the predetermined entropy slice, but also on the estimates of probability, which are used at entropy coding of spatially adjacent, by the order number of entropy slices, previous entropy slice in its adjacent part. Therethrough, the estimations of probability used at entropy coding are adapted to actual statistical information of a symbol more closely, thus reducing the coding efficiency reduction usually caused by concepts of lower delay. Time correlations are used additionally or alternatively.
EFFECT: possibility of reducing delay when coding arrays of samples.
