| Abstract: | A framework for H.264 based fine granularity scalable video coder and the encoding method of residue coefficient in enhancement layer are analyzed.Then,an H.264 based real time FGS encoder is proposed.Test results indicate that the optimized FGS encoder can satisfy the real-time requirement,but compared with the original FGS encoder,its PSNR decreases and its coderate increases. |

| Keywords: | real time FGS bit-plane coding encoding method |
