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

摘要

FIELD: physics, video.SUBSTANCE: invention relates to video encoding and decoding. The method for encoding video includes: encoding the video data of the maximum coding unit based on deeper coding units of hierarchical structures according to at least one split region of the maximum coding unit, while performing inter-prediction using partitions obtained by splitting the coding unit according to arbitrary ratios, and determining coding depth; and outputting a bitstream including the coded video data corresponding to the coding depth according to the maximum coding unit and information regarding the coding depth and coding modes.EFFECT: high efficiency of compressing an image while simultaneously increasing the maximum size of a coding unit based on the image size.5 cl, 1 tbl, 21 dwg
