Abstract:
Provided are a method and apparatus for encoding a video and a method and apparatus for decoding a video. The encoding method includes: splitting a picture of the video into one or more maximum coding units; encoding the picture based on coding units according to depths which are obtained based on a partition type determined according to the depths of the coding units according to depths, determining coding units according to coded depths with respect to each of the coding units according to depths, and thus determining coding units having a tree structure; and outputting data that is encoded based on the partition type and the coding units having the tree structure, information about the coded depths and an encoding mode, and coding unit structure information indicating a size and a variable depth of a coding unit.

Claim (Index 7):
A non-transitory computer-readable storage medium storing a bitstream, the bitstream comprising:\n coding unit structure information about a size of coding units, wherein the coding units are data units for encoding a picture of a video; information about a variable depth of the coding units, wherein a maximum coding unit is hierarchically split into the coding units according to depths in the variable depth; and information about a coded depth to indicate whether a coding unit of a depth, among the coding units, is not split into smaller coding units, wherein:\n a prediction unit is determined from the coding unit of the coded depth which is no longer splint into smaller coding units, \n when prediction is performed in a skip mode, a prediction unit having a same size as the coding unit of the coded depth is used for prediction on the coding unit of the coded depth, \n when prediction is performed in an intra mode, a prediction unit including at least one square block is determined from the coding unit of the coded depth and used for prediction on the coding unit of the coded depth, and \n when prediction is performed in an inter mode, a prediction unit including one of a partition, symmetric partitions and asymmetric partitions, is determined from the coding unit of the coded depth, and used for prediction on the coding unit of the coded depth, wherein the symmetric partitions are obtained by symmetrically splitting at least one of a height and a width of the coding unit of the coded depth, and the asymmetric partitions are obtained by asymmetrically splitting one of the height and the width of the coding unit of the coded depth.
