| Abstract: | MPEG provides scalable solution that can fit for MPEG-4 standard. The problem is that the coding efficiency of FGS is a low,so it is necessary to improve it. This paper analyzes various improvement schemes based on FGS such as Macroblock- based improved FGS and motion compensation FGS. Various coding schemes are studied and compared. |

| Keywords: | MPEG-4 scalability FGS macroblock-based improved FGS motion-compensation FGS |
