DEVICE AND METHOD FOR VIDEO ENCODING AND VIDEO DECODING Russian patent published in 2023 - IPC H04N19/119 H04N19/176 H04N19/70 

FIELD: video encoding/decoding.

SUBSTANCE: invention relates to means for video encoding and decoding. A number of blocks to be assigned in sections is determined, which is one of the following: a width of an image in coding tree units (hereinafter – CTU), a height of an image in CTU, a number of CTU rows in a tile. A number of sections of an explicitly set size to be assigned is specified. Sizes of sections of an explicitly set size or a number of blocks in them are specified. A number of sections of an equal size to be assigned is logically obtained. The mentioned logical obtainment of the number of sections of an equal size to be assigned includes: determination of a number of blocks still to be assigned in sections by subtracting a number of blocks in sections of an explicitly set size from a number of blocks to be assigned in sections; assignment of sections to be sections of an explicitly set size in accordance with sizes or a number of blocks in sections of an explicitly set size and in accordance with a preset or specified scanning order, and assignment of sections to be sections of an equal size by dividing blocks still to be assigned in sections by a number of sections of an equal size in accordance with the preset or specified scanning order.

EFFECT: increase in the efficiency of video encoding.
