FIELD: video encoding.

SUBSTANCE: invention relates to means for video encoding. A syntaxis element is obtained from a bit stream. Information on the minimum size, MinQtSizeY, is obtained in brightness samples of a leaf brightness block obtained as a result of separation of a quadrant tree. The maximum size, MaxBtSizeY, is determined in brightness samples of a root brightness block, so that it can be separated using separation of a binary tree, based on MinQtsizeY information and the obtained syntaxis element. Moreover, the syntaxis element is an element of syntaxis of the difference between a logarithm of the base 2 of MinQtSizeY and a logarithm of the base 2 of MaxBtSizeY; or the syntaxis element is an element of syntaxis of the difference between MinQtSizeY and MaxBtSizeY, wherein the difference syntaxis element indicates the mentioned difference in a logarithmic form with the base 2. At the same time, the method additionally contains stages, at which: it is determined whether it is allowed for application of binary separation to an image block based on MaxBtSizeY; and an encoding block of the image block is obtained based on the result of determination.

EFFECT: increase in the efficiency of video encoding due to an increase in the efficiency of image separation.
