METHOD OF USING INTERPOLATION FILTERS TO PREDICT MOTION VECTOR BASED ON HISTORY Russian patent published in 2024 - IPC H04N19/117 

FIELD: methods; devices; systems for video processing.

SUBSTANCE: maintaining, prior to conversion between the current video block of video and the encoded video representation, at least one history-based motion vector prediction (HMVP) table, wherein the HMVP prediction table contains one or more positions corresponding to motion information of one or more previously processed blocks; and performing a conversion using the at least one HMVP prediction table; wherein the motion information for each position is configured to include interpolation filter information for said one or more previously processed blocks, wherein the interpolation filter information indicates interpolation filters used to interpolate prediction blocks for said one or more previously processed blocks.

EFFECT: increasing video encoding efficiency.
