    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.

    Abstract: Provided are a method and apparatus for encoding or decoding a coding unit on an outline of a picture. An image decoding method and apparatus according to an embodiment determine whether a current coding unit extends across an outline of a picture, by comparing a location of the current coding unit in the picture to at least one of a width and a height of the picture, split the current coding unit in at least one direction into a plurality of coding units based on a shape of the current coding unit upon determining that the current coding unit extends across the outline of the picture, obtain block shape information and split type information of the current coding unit from a bitstream and split the current coding unit into a plurality of coding units based on the block shape information and the split type information upon determining that the current coding unit does not extend across the outline of the picture, and decode a coding unit that is no longer split among the plurality of coding units.
