SYSTEM AND METHOD FOR SCALABLE ENCODING AND DECODING OF MULTIMEDIA DATA USING MULTIPLE LAYERS

摘要

A method of processing multimedia data being associated with multiple layers is disclosed. The method may include determining a base layer residual and performing interlayer prediction to generate an enhancement layer residual if at least one of a number of non-zero coefficients of the base layer residual or a number of zero coefficients of the base layer residual meets a first selected condition. A method of decoding a multimedia bitstream may include receiving a multimedia bitstream having a base layer and an enhancement layer and decoding the base layer to determine whether the enhancement layer should be decoded using intralayer prediction or interlayer prediction.
