VIDEO ENCODING METHOD, VIDEO DECODING METHOD, VIDEO ENCODING DEVICE, VIDEO DECODING DEVICE AND PROGRAM Russian patent published in 2020 - IPC H04N19/13 H04N19/91 H04N19/96 

FIELD: calculating; counting.

SUBSTANCE: invention relates to the computer equipment. Video encoding method using a block breakdown structure based on a quadtree and a binary tree, comprising a step of entropy coding a flag indicating, whether or not the block is broken based on the structure of the quadtree; a step of entropy encoding of the pass flag of the end node in the quadtree structure; a step of entropy encoding a flag indicating whether or not the end node block is broken in the quadtree structure based on the binary tree structure and the horizontal/vertical crushing direction flag indicating the crushing direction; and a step of multiplexing information indicating a minimum partition size based on the structure of the binary tree, into a bit stream, wherein in case the unit of size equal to the minimum size is additionally broken on the basis of the binary tree structure, the horizontal/vertical crushing direction flag in the node is not entropy coded.

EFFECT: technical result consists in improvement of compression efficiency.
