Abstract RU 2780422 C1

FIELD: encoding.

SUBSTANCE: invention relates to video encoding tools. The encoded information of the coding block (CB) is decoded in an image from the bitstream of the encoded video, wherein the encoded information indicates the width of the CB equal to W counts and the height of the CB equal to H counts. The CB is divided into sub-processing units (SPU) with a width and height, wherein the width of a SPU is equal to the minimum value from W and K, or the height of a SPU is equal to the minimum value from H and K. At least one of the width W and height H for the CB herein is greater than the size K of the processing data unit. The partitioning structure for the additional partitioning of the SPU is determined based on the width and height of the SPU and the maximum size of the transformation unit (TU), constituting M samples, wherein at least one from the width and height of the SPU is greater than M. Each of the SPU is divided into TUs with the dimensions M×M based on the determined partitioning structure.

EFFECT: increase in the efficiency of video encoding.
