摘要:

随着无线宽带网络的快速发展,以及高效的视频压缩技术的应用,流媒体的实时高效传输成为亟待解决的问题。本文从视频传输系统模型入手,分析了最新视频编码标准H.264在算法上的层次结构特点以及音、视频实时传送协议RTP的高效性。并且随着适合H.264流的RTP载荷格式的提出,基于RTP的H.264流媒体无线传输渐渐地得到应用。本文成功实现了一种基于RTP的H.264传输算法,实验通过了TD330无线3G模块测试,并且获得良好的图像质量,实现了低时延、较小丢包率的打包算法。

Abstract:

Along with the rapid development of wireless broadband networks, and the application of efficient video compression technology, realtime efficient transmission of streaming media becomes serious problems to be solved. The paper introduces a video transmission system model, and analyses the layer structure characteristics for algorithms and the efficient sound, video realtime transmission RTP protocols of the latest video coding standard H.264. And the RTP load format of the H2.64 video is put forward. The H.264 streaming media based on RTP wireless transmission gradually comes into use. This article successfully implementats the H.264 transfer algorithm based on RTP. Through the TD330 wireless 3G module, the experiment obtains good image quality testing, and realizes a packing algorithm of low delay, smaller packet loss.
