MAINTAINING TABLES FOR STORING CANDIDATES FOR PREDICTION OF MOTION VECTOR BASED ON HISTORY Russian patent published in 2023 - IPC H04N19/52 H04N19/119 H04N19/513 

Abstract RU 2808631 C2

FIELD: video encoding/decoding.

SUBSTANCE: video processing method is proposed, comprising: determining, during conversion between a first block of visual media data and a corresponding encoded representation of the visual media data, a first block encoded in a geometric partitioning mode; determining, based on at least one table storing history-based motion vector prediction (HMVP) candidates that include motion information based on previously encoded blocks, motion information of at least one sub-part of the first block; transforming the first block using certain motion information.

EFFECT: increase in the efficiency of encoding/decoding.
