METHOD AND APPARATUS FOR VIDEO ENCODING CONSIDERING SCANNING ORDER OF CODING UNITS WITH HIERARCHICAL STRUCTURE, AND METHOD AND APPARATUS FOR VIDEO DECODING CONSIDERING SCANNING ORDER OF CODING UNITS WITH HIERARCHICAL STRUCTURE

摘要

A method for decoding a video is disclosed. The method includes: receiving and parsing a bitstream of an encoded video; extracting encoded image data of a current picture assigned to a maximum coding unit that is a coding unit with a maximum size, and information about a coding depth and an encoding mode of each maximum coding unit; and decoding the encoded image data of each maximum coding unit based on the extracted information about the coding depth and the encoding mode of each maximum coding unit in consideration of a raster scan order of the maximum coding units and a zigzag scan order of coding units by depth.
