METHOD AND APPARATUS FOR VIDEO ENCODING BY MOTION PREDICTION USING ARBITRARY PARTITION, AND METHOD AND APPARATUS FOR VIDEO DECODING BY MOTION COMPENSATION USING ARBITRARY PARTITION

摘要

Disclosed are a method and an apparatus for encoding a video. The method for encoding a video comprises splitting video data into at least one maximum coding unit which is a coding unit of a maximum size; encoding the video data of the maximum coding unit based on hierarchical coding units according to depths of the split region of the maximum coding unit, including inter prediction using partitions obtained by splitting the coding unit at an arbitrary ratio; determining a coding depth at which an encoding result is to be output; and outputting a bit stream including the encoded video data corresponding to the coding depth of each split region and information about the coding depth and an encoding mode of each maximum coding unit.
