A SNR Scalability Scheme Based on  the H.264/AVC Video Coding Standard

Abstract:  This paper proposes  an efficient SNR  scalable  extension  for  the  H.264/AVC  video  coding standard.  The  coder  consists  of  two  motion compensated  sub-coders  generating  the  base  and  the enhancement  layers. The  base layer is  fully H.264 compatible while the enhancement layer  bitstream has been  modified. The enhancement layer coder uses the information  of both layers  in  order to improve the coding efficiency
