METHOD AND APPARATUS FOR PROCESSING A VIDEO SIGNAL BASED ON A HISTORY-BASED PREDICTION OF THE MOTION VECTOR Russian patent published in 2022 - IPC H04N19/503 H04N19/105 

FIELD: data encoding.

SUBSTANCE: invention relates to the field of encoding for performing inter-frame prediction using a history-based prediction of the motion vector. Proposed is a method for processing video signals based on an inter-frame prediction, including the stages of: configuring a list of candidates for merging based on the spatial adjacent block and the temporal adjacent block of the current block; adding a history-based candidate for merging of the current block to the list of candidates for merging; obtaining a merge index indicating the candidate for merging, used to make an inter-frame prediction of the current block, in the list of candidates for merging; forming a sample of prediction of the current block based on the information about the movement of the candidate for merging, indicated by the merge index; and updating the list of history-based candidates for merging based on the information about the movement.

EFFECT: provided limitation on the redundancy check in order to increase the efficiency of prediction when adding an HMVP candidate to the list of candidates for merging (or the list of AMVP candidates).
