SCALABLE VIDEO ENCODING AND DECODING METHOD AND APPARATUS USING SAME

摘要

An interlayer prediction method according to the present invention comprises: a step of determining the position of a reference criteria sample corresponding to an enhancement criteria sample in a reference layer on the basis of the position of an enhancement criteria sample that belongs to an enhancement layer; a step of determining at least one reference layer block in the reference layer on the basis of the position of the reference criteria sample; and a step of predicting the current block that belongs to the enhancement layer on the basis of the movement information of said at least one reference layer block.
