Abstract:
1. A method of decoding a video, the method comprising: parsing a bitstream of encoded video data; determining at least one coding unit included in a maximum coding unit by using split information parsed from the bitstream; and determining partitions for performing inter prediction on a coding unit among the at least one coding unit, by using information about a partition type of the coding unit, parsed from the bitstream; performing motion compensation using the partitions of the coding unit, wherein: the partitions are rectangles obtained by splitting at least one of a height and a width of the coding unit according to a symmetric ratio of 1:1 or by splitting one of the height and the width of the coding unit according to an asymmetric ratio of 1:3 or 3:1, the image is split into a plurality of maximum coding units, according to information about a maximum size of a coding unit, the maximum coding unit is hierarchically split into one or more coding units of depths according to the split information, a coding unit of a current depth is one of rectangular data units split from a coding unit of an upper depth, when the split information indicates a split for the current depth, the coding unit of the current depth is split into coding units of a lower depth, independently from neighboring coding units, and when the split information indicates a non-split of the lower depth, the coding unit of the lower depth is split into the partitions.
