METHOD AND APPARATUS FOR VIDEO ENCODING CONSIDERING HIERARCHICAL CODED BLOCK PATTERN, AND METHOD AND APPARATUS FOR VIDEO DECODING CONSIDERING HIERARCHICAL CODED BLOCK PATTERN

摘要

PURPOSE: A method for video encoding and decoding considering hierarchical coded block pattern is provided to notify whether the textual information of the encoding unit was encoded or not in consideration of hierarchicals depth. CONSTITUTION: A video decoding method comprises a step(1210) in which bitstream about a encoded video is received and performed parsing, and a step(1220) for extracting encoded video data of the picture allocated in the maximum encoding unit, information about the maximum encoding unit coding depth and encoding mode, and pattern information which shows whether the textual information of the maximum encoding unit was encoded or not, and a step(1230) for decoding a encoded video data by the maximum encoding unit depth, and encoding mode information.
