METHOD AND APPARATUS FOR VIDEO ENCODING USING TRANSFORMATION UNIT IN VARIABLE TREE-STRUCTURE, METHOD AND APPARATUS FOR VIDEO DECODING USING TRANSFORMATION UNIT IN VARIABLE TREE-STRUCTURE

摘要

Disclosed is a method for video encoding using transformation units of a variable tree-structure, for encoding a current area among a video, performing transformation of the current area based on transformation units of a variable tree structure generated based on a maximum division level of the transformation units, and outputting transformation unit level hierarchy information including information of encoding data of the current area and an encoding mode, and information of maximum size and information of minimum size of the transformation units of the video.
