| 摘 要： | 提出了一种针对H.264可分级编码(H.264 SVC)的自适应前向纠错编码保护方案.通过比较不同的纠错方案,提出了划分丢包率区间的概念,并根据不同区间的丢包率自适应地选择最佳的纠错方案.仿真结果表明,与单一保护方法相比,所提自适应方法能够取得更好的保护效果,更适于在无线信道中进行视频传输.

| Abstract: | A novel adaptive forward error correction(FEC) protection scheme for H.264 scalable video coding(H.264 SVC) was proposed.After proposing and comparing several FEC error protection schemes,we classified the wireless channel into different intervals in terms of packet loss ratio,and chose the optimal protection scheme in each interval.Simulation results show that the proposed adaptive scheme has better performance than other single protection schemes,thus it is more suitable for wireless video transmission. |
