本文提出了一种无线衰落信道中进行H.264视频传输的不等差错保护方案。这种方案通过对视频流的不同重要性的部分进行不同码率的删余卷积信道编码和一种特殊的重传机制来实现不等差错保护机制。仿真结果显示,该方案可以有效改善视频传输的性能,提高视频传输的鲁棒性。
This paper presents an unequal error protection scheme for H.264 video transmission in wireless fading channels. This scheme achieves Unequal Error Protection by puncturing convolutional channel coding with different code rates and a special retransmission mechanism on the different parts of the video stream. Simulation results show that this scheme can effectively improve the performance of video transmission and improve the robustness of video transmission.
