Abstract
A method and apparatus for decoding video and a method and apparatus for encoding video are provided. The method for decoding video includes: receiving and parsing a bitstream of encoded video; extracting, from the bitstream, encoded image data of a current picture assigned to a maximum coding unit of the current picture, information regarding a coded depth of the maximum coding unit, information regarding an encoding mode, and coding unit pattern information indicating whether texture information of the maximum coding units has been encoded; and decoding the encoded image data for the maximum coding unit, based on the information regarding the coded depth of the maximum coding unit, the information regarding the encoding mode, and the coding unit pattern information.
