Claim Text:
1. An apparatus for decoding a video, the apparatus comprising at least one processor which implements: a parser configured for parsing asymmetric partition information indicating whether partition types include asymmetric partition types, from a bitstream of an encoded image, and a coding unit determiner configured for determining at least one coding unit included in a maximum coding unit by using split information parsed from the received bitstream, a predictor configured for determining at least one prediction unit of a coding unit among the at least one coding unit, by using the asymmetric partition information and information about a partition type of the coding unit parsed from the received bitstream, and performing motion compensation using the prediction units for the coding unit, wherein: when the asymmetric partition information indicates that the partition types include the asymmetric partition types, the predictor is configured for determining the at least one prediction unit according to a particular type among the partition types including asymmetric partition types and symmetric partition types, by using information about a partition type of the coding unit; and when the asymmetric partition information indicates that the partition types do not include the asymmetric partition types, the predictor is configured for determining the at least one prediction unit according to a particular type among the partition types including symmetric partition types by using the information about a partition type of the coding unit.
