FIELD: video encoding.
SUBSTANCE: line of reference readings of the current block is defined. It is determined whether there is a candidate internal prediction mode that is the same as the internal prediction mode of the current block. The internal prediction mode of the current block is obtained based on the determination. Internal prediction is performed on the current block based on the reference sample line and the internal prediction mode. Additionally, it is determined whether the current block should be divided into a plurality of sub-blocks. When a current block is divided into a plurality of sub-blocks, the plurality of sub-blocks shares the same internal prediction mode. The horizontal direction transformation type and the vertical direction transformation type of the sub-block are determined based on the shape of the sub-block.
EFFECT: improved efficiency of video encoding.
