METHOD AND APPARATUS FOR ENCODING AND DECODING VIDEO BY USING PATTERN INFORMATION IN HIERARCHICAL DATA UNIT

摘要

Video encoding using pattern information of a hierarchical data unit includes performing encoding that is accompanied by transformation based on at least one transformation unit of every coding unit for at least one depth, for regions reduced by hierarchically splitting maximum coding units according to depths, with respect to each of the maximum coding units, determining a coding unit of at least one coded depth to output an encoding result, and outputting pattern information indicating whether texture related information is encoded based on a hierarchical structure of the maximum coding units, the coding units, and the transformation units.
