METHOD OF ENCODING VIDEO AND DEVICE FOR ENCODING VIDEO BASED ON CODING UNITS DEFINED ACCORDING TO TREE STRUCTURE, AND METHOD OF DECODING VIDEO AND DEVICE FOR DECODING VIDEO BASED ON CODING UNITS DEFINED ACCORDING TO TREE STRUCTURE Russian patent published in 2016 - IPC G06T9/40 H04N19/169 

Abstract RU 2597471 C2

FIELD: information technologies.

SUBSTANCE: invention relates to encoding/decoding video. Method of decoding video comprises steps of receiving a bit stream relative to the encoded video and its syntactical analysis; receiving data of coding units structure indicating the size and variable depth of a coding unit, and information relative to encoded depth and encoding mode relative to the coding units having a tree image structure; determining the coding units having a tree structure based on data of coding units structure and information relative to encoded depth and encoding mode and decoding the image based on the coding units; herewith the data of coding units structure contains information relative to the minimum size of the coding unit and information on change of the coding unit depth.

EFFECT: higher efficiency of compressing and decoding images.
