Abstract:
1. A method of decoding a video, the method comprising: parsing asymmetric partition information indicating whether partition types include asymmetric partition types, from a bitstream of an encoded image; determining at least one coding unit included in a maximum coding unit by using split information parsed from the received bitstream; 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 the determining at least one prediction unit comprises: when the asymmetric partition information indicates that the partition types include the asymmetric partition types, 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, 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.
