| Abstract: | Principle of scalable coding is introduced firstly in this paper. In addition, based on the analysis of several typical fine granularity scalability (FGS) methods, an H.264 FGS codec has been proposed and the transport performance of FGS bit streams over IP networks is minutely analyzed. The proposed scheme has been proved with good performance by simulation results. |
