FIELD: physics.
SUBSTANCE: method includes restoring a group of possible intra-frame prediction modes of the colour component prediction unit by excluding the intra-frame prediction mode of the colour component prediction unit, which is the same as the intra-frame prediction mode of the luminance component prediction unit from the group of possible intra-frame prediction or replacement mode embodiments of the colour component prediction unit, which is the same as the prediction mode of the luminance component, for another intra-frame prediction mode, and coding the intra-frame prediction mode of the colour component prediction unit by using the reduced group of possible embodiments the intra-frame prediction mode.
EFFECT: improving the quality of images by increasing the efficiency of encoding and decoding video signals in the intra-frame prediction mode.
