METHOD AND APPARATUS FOR SCALABLE ENCODING AND DECODING

摘要

PURPOSE: A scalable video coding and decoding method and an apparatus using the same are provided to provide various video services in terms of time, space, and/or image quality according to the various demands or utility purpose of a user. CONSTITUTION: An encoding/decoding apparatus determines whether to apply an inter layer prediction to an enhancement layer or not(S1610). In case the inter layer prediction is applied, the apparatus performs prediction about the current block of the enhancement layer based on generalized reference information generated from the information of a reference layer(S1630). The apparatus restores or encodes the current picture of the enhancement layer(S1640).
