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 encoding a video using a transformation unit of a variable tree-structure, which performs transformation on a current area based on transformation units of a variable tree-structure generated based on a maximum division level of the transformation unit among transformation units hierarchically divided from a basic transformation unit of the current area for encoding the current area among video, and outputs transformation unit hierarchy structure information including encoding data of the current area and information of an encoding mode, and information of maximum size and minimum size of the transformation unit of the video.
