FIELD: video coding and decoding.
SUBSTANCE: method is proposed for entropy decoding of video data, which includes the steps of: retrieving a predefined initialization value for a context from a plurality of contexts that are used in a context-adaptive entropy encoding process to entropy encode a value for a syntax element for an independently encoded unit of video data; determining, based on the predetermined initialization value and in a linear domain, an initial probabilistic state of the context; and entropically decode, from the bit stream and based on the initial probabilistic state of the context, a value bin for the syntax element.
EFFECT: increase of efficiency of encoding/decoding.
