METHOD FOR CODING VIDEO AND DEVICE FOR VIDEO CODING ON BASIS OF CODING UNITS DEFINED IN ACCORDANCE WITH TREE-LIKE STRUCTURE, AND METHOD FOR DECODING VIDEO AND DEVICE FOR DECODING VIDEO ON BASIS OF CODING UNITS DEFINED IN ACCORDANCE WITH TREE-LIKE STRUCTURE Russian patent published in 2018 - IPC G06T9/40 H04N19/96 H04N19/134 H04N19/119 

FIELD: data processing.

SUBSTANCE: invention relates to video encoding and decoding. This method for decoding video includes: receiving an encoded video bitstream; extracting information on the size of a coding unit from the received bit stream, which is a data unit for decoding an image of an encoded video, a variable depth of a coding unit, partitioning information and a coding mode regarding coding units having a tree structure of the image; determining the maximum size of a coding unit; splitting an image into one or more maximum coding units based on a specific maximum size; determining coding units having a tree structure based on the partitioning information; and decoding the image based on the encoding mode.

EFFECT: improving the efficiency of encoding and decoding video by using a hierarchical unit of coding.
