METHOD AND APPARATUS FOR ENCODING AND DECODING FGS LAYER USING RECONSTRUCTED DATA OF LOWER LAYER

摘要

A method and apparatus for encoding and decoding a fine granularity scalable (FGS) layer using reconstructed data of a lower layer. The method includes encoding the FGS layer in a multilayer video signal includes reconstructing original data of the lower layer that corresponds to a low-pass frame represented by the FGS layer, obtaining a residual between original data of the enhancement layer and the reconstructed original data of the lower layer, and generating an FGS layer bitstream through the processes of quantizing the residual and performing an entropy coding of the quantized residual.
