METHOD AND APPARATUS FOR ENCODING VIDEO BY MOTION PREDICTION USING ARBITRARY PARTITION, AND METHOD AND APPARATUS FOR DECODING VIDEO BY MOTION PREDICTION USING ARBITRARY PARTITION

摘要

An apparatus for decoding a video by 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.

1. An apparatus for decoding a video, the apparatus comprising:a processor which is configured for:
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:
when the asymmetric partition information indicates that the partition types include the asymmetric partition types, the processor 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 processor 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.
