METHOD FOR PADDING PROCESSING BY PARTS OF SUB-AREAS IN A VIDEO STREAM Russian patent published in 2023 - IPC H04N19/70 H04N19/46 H04N19/513 H04N19/80 H04N19/186 

FIELD: video coding.

SUBSTANCE: encoded syntax elements corresponding to the cyclic padding process are decoded based on the offset of the reference block by the reference cyclic padding width value, which is determined based on the locations of the luminance samples in the reference block. At least one coded current picture is restored using a cyclic padding process. The syntax elements indicate the offset value for loop processing; or information about the width of the left and right fill. The flag indicates whether syntax elements corresponding to the cyclic padding process are present in the parameter set. The position of a pixel for motion-compensated prediction in a reference image is determined by interpreting the syntax elements corresponding to the cyclic padding process with a clipping process.

EFFECT: increase in the efficiency of coding.
