FIELD: means for video encoding.
SUBSTANCE: reconstructed discrete sample of the current block and prediction-related information for the current block are generated. At the same time, a list of potentially suitable variants of the intra-prediction modes of the current block is constructed, including the DC intra-prediction mode, based on the intra-prediction modes of neighbouring blocks relative to the current block. The intra-prediction mode of the current block is retrieved based on the list of potentially suitable variants of intra-prediction modes. A discrete prediction sample of the current block is retrieved based on the intra-prediction mode. The intra prediction types include a first intra prediction type using an intra prediction reference line adjacent to the current block, a second intra prediction type using an intra prediction reference line not adjacent to the current block, and a third intra prediction type, to which the mode based on intra-subsegments is applied.
EFFECT: increase in efficiency of image encoding.
