METHOD AND DEVICE FOR PROCESSING VIDEO SIGNAL BASED ON HISTORY-BASED MOTION VECTOR PREDICTION Russian patent published in 2023 - IPC H04N19/503 H04N19/105 

FIELD: encoding.

SUBSTANCE: invention relates to the encoding for performing inter-frame prediction using history-based motion vector prediction. Devices for encoding and decoding images are proposed. The devices perform video signal processing based on interframe prediction and comprise the steps of: configuring a list of merge candidates based on a spatial neighbour block and a temporal neighbour block of the current block; adding the current block based on the history of the merge candidate to the list of merge candidates; obtaining a merge index indicating a merge candidate that is used for inter-frame prediction of the current block in the merge candidate list; generating a prediction sample of the current block based on the motion information of the merge candidate indicated by the merge index; and updating the list of history-based merger candidates based on the traffic information.

EFFECT: providing a constraint on redundancy checking to improve prediction performance when adding an HMVP candidate to a merge candidate list (or AMVP candidate list).
