METHOD, APPARATUS AND DEVICE FOR ENCODING AND DECODING Russian patent published in 2023 - IPC H04N19/119 H04N19/513 

FIELD: video image encoding and decoding.

SUBSTANCE: separating, if the characteristic information of the current block meets the given conditions, the current block into the first triangular subblock and the second triangular subblock; building a motion information list for the current block, the motion information list including a plurality of candidate motion information items; obtaining the first target motion information for the first triangular subblock and the second target motion information for the second triangular subblock from the list of motion information, the first target motion information being different from the second target motion information; performing motion compensation on the first triangular subblock based on the first target motion information to obtain a prediction value for the first triangular subblock; and performing motion compensation on the second triangular subblock based on the second target motion information to obtain a prediction value for the second triangular subblock.

EFFECT: increasing video encoding efficiency.
