FIELD: video data coding.
SUBSTANCE: invention relates to the field of video data coding. A method for decoding video data is proposed, including receiving, from a bitstream of encoded video data, a syntax element associated with the current coding block, which is divided into the first part and the second part along the edge of the division for prediction in the geometric separation mode, and determining the weight index at the reference position of the current block coding. The stored motion vector type for the first motion storage unit in the motion field of the current coding block is determined based on the motion index of the first motion storage unit. The weight index at the reference position of the current coding block is used as the motion index of the first motion storage unit. The motion field of the current coding block may be stored based on the stored motion vector type determined for the first motion storage unit in the motion field of the current coding block.
EFFECT: improving coding efficiency.
