VIDEO ENCODING METHOD AND APPARATUS, AND VIDEO DECODING METHOD AND APPARATUS Russian patent published in 2014 - IPC H04N19/122 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to video encoding and decoding. Disclosed is a video encoding method which comprises steps of: dividing a current picture into at least one maximum coding unit, determining encoded depth to derive the final encoding result according to at least one division region obtained by dividing the maximum the region of the maximum coding unit according to depths, by encoding at least one division region based on depth which is increased in proportion to the number of times the region of the maximum coding unit is divided; and outputting image data constituting the final encoding result according to at least one division region, and encoding information on encoded depth and a prediction mode according to at least one maximum encoding unit.

EFFECT: encoding and decoding an image based on a hierarchical encoding unit of a different size.
