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 6):
A method of encoding a video, the method comprising:\n determining coding units that are data units for encoding a picture of the video; generating coding unit structure information about a size of the coding units, and information about a variable depth of the coding units; and generating information about a coded depth, and an encoding mode indicating one among prediction modes including skip mode, inter mode and intra mode, wherein a coding unit of the coded depth, among the coding units, is encoded in the encoding mode, wherein the determining the coding units comprises:\n determining a plurality of maximum coding units by splitting an image according to the size of the coding units and the variable depth of the coding units; \n hierarchically splitting a maximum coding unit, among the plurality of maximum coding units, into coding units according to depths; and \n determining the coding unit of a current depth by dividing a height and width of a coding unit of an upper depth by two, \n wherein the generating the information about the coded depth, and the encoding mode comprises:\n when the coding unit of the current depth is split into coding units of a lower depth, independently from neighboring coding units, generating the information about the coded depth to indicate a split for the current depth; \n when the coding unit of the current depth is not split into the coding units of a lower depth and prediction is performed on the coding unit of the current depth, generating the information about the coded depth to indicate a non-split of the current depth; \n when prediction is performed in the skip mode using a prediction unit having a same size as the coding unit of the current depth, generating the encoding mode to indicate the skip mode; \n when prediction is performed in the intra mode using a prediction unit including at least one square block determined from the coding unit of the current depth, generating the encoding mode to indicate the intra mode; and \n when prediction is performed in the inter mode using a prediction unit including one of a partition, symmetric partitions and asymmetric partitions, determined from the coding unit of the current depth, generating the encoding mode to indicate the inter mode, wherein the symmetric partitions are obtained by symmetrically splitting at least one of a height and a width of the coding unit of the current depth, and the asymmetric partitions are obtained by asymmetrically splitting one of the height and the width of the coding unit of the current depth.
