FIELD: physics, video.
SUBSTANCE: invention relates to means of encoding and decoding video. The method includes determining a first most probable intra-prediction mode and a second most probable intra-prediction mode for a current block of video data based on a context for the current block; performing a context-based adaptive binary arithmetic coding (CABAC) process to determine a received codeword, corresponding to a modified intra-prediction mode index; determining the intra-prediction mode index; selecting the intra-prediction mode.
EFFECT: high efficiency of signalling an intra-prediction mode used to encode a data block by providing relative saving of bits for an encoded bit stream.
