基于RTP自适应分包的视频无线传输技术
Technology of Video Wireless Transmission Based on RTP’s Adaptive Packeting Algorithm
本文重点研究了MPEG-4码流的RTP分包问题。传输中的丢包率和RTP包的长度有关，为了在无线信道中降低丢包率，改善解码的效果，文章在RFC3016的基础上，提出了一种能够根据网络状态的变化调整RTP包的大小的自适应分包算法。最终在ARM系统上实现了高分辨率视频图像的采集、编码、无线发送等。实验结果表明，该方法能较好地改善大数据量视频信号的无线传输质量。
his paper focus on the RTP packeting problem of MPEG-4 streams. The packet-loss rate relates to the RTP packets’ length. In order to decrease the packet-loss rate and improve the decode effect when the signal is transmitted in wireless channel, this paper provided an adaptive algorithm which can adjust the RTP packet size automatically by the network condition, based on RFC3016.Finally the scheme has been implemented on ARM system including capturing and encoding high definition video picture, wireless transmission and so on. The experimental result has proved that the algorithm can improve the wireless transmission quality of video signal with big data size.
