FIELD: physics, computer engineering.
SUBSTANCE: invention relates to video encoding and decoding. The method of encoding video involves determining encoding units having a tree structure, which include encoding units of encoded depths, and determining encoding modes for encoding units of encoded depths by encoding based on units for encoding according to depths. The units for encoding according to depths are obtained via hierarchical breakdown of the maximum encoding unit as the depth increases. Further, information is output, which indicates the order of the breakdown information and omission mode information which is selectively determined for units for encoding according to depths, and information relating to encoding modes for encoding units of encoded depths, which includes breakdown information and omission mode information arranged according to the order.
EFFECT: providing an optimum encoding mode based on characteristics of encoding units of different image sizes.
