METHOD AND APPARATUS FOR ENCODING VIDEO BASED ON SCANNING ORDER OF HIERARCHICAL DATA UNITS, AND METHODS AND APPARATUS FOR DECODING VIDEO BASED ON SCANNING ORDER OF HIERARCHICAL DATA UNITS

摘要

A video decoding method and apparatus and a video encoding method and apparatus based on a scanning order of hierarchical data units are provided. The decoding method includes: receiving and parsing a bitstream of an encoded video; extracting from the bitstream encoding information about a coded depth and an encoding mode for coding units of the picture; and determining a hierarchical structure of the maximum coding unit and the coding units into which the picture is divided according to depths, and decoding the picture based on the coding units, by using the encoding information about the coded depth and the encoded mode.
