【Abstract】 This paper proposes an improved approach that based on MPEG4 FGS, named IFGS Unlike the FGS scheme, the IFGS scheme provides much high quality prediction reference frames in enhancement layer coding, and eliminates the data redundancies by the correlation of the DCT residue coefficients Experimental results show the improved method is higher coding efficiency than that of the original FGS in MPEG4更多还原
