METHOD FOR CODING VIDEO BY MOTION PREDICTION USING ARBITRARY PARTITIONS AND APPARATUS THEREOF, AND METHOD FOR DECODING VIDEO BY MOTION COMPENSATION USING ARBITRARY PARTITIONS AND APPARATUS THEREOF

摘要

PROBLEM TO BE SOLVED: To provide video coding and video decoding by inter prediction using arbitrary shapes of partitions.SOLUTION: Disclosed is a method and an apparatus thereof of coding video, the method including: splitting video data into at least one maximum coding unit which is a coding unit of the maximum size; including inter prediction using partitions obtained by splitting the coding units according to arbitrary ratio; coding the video data of the maximum coding unit on the basis of depth-dependent coding units of hierarchical structures, according to at least one split region of the maximum coding unit; determining coding depth at which a coding result is to be output; and outputting a bitstream including the coded video data corresponding to the coding depth for the split region according to the maximum coding units, and also including information regarding the coding depth and coding modes.SELECTED DRAWING: Figure 1
