【摘要】 随着多媒体应用的发展,有线和无线网络上的实时流媒体传输技术已成为研究热点。本文首先介绍了基于RTP的H．264传输模型,在此基础上提出了适用于H．264实时视频流传输的RTP组包算法 HMP。该算法针对H．264NAL视频流特点,在考虑到视频流关联性的同时加入了对重要信息的保护。实验结果证明,HMP算法在网络丢包率较大的情况下仍能获得良好视觉质量。更多还原

【Abstract】 With the development of multimedia application, real-time video streaming over wired/wireless network has become a focus of research. This paper describes a H.264 real-time transmission module based on RTP, and puts forward a RTP packetization algorithm for H.264 video which is called Hybrid Mode Packetization (HMP). HMP considers video stream content correlation and unequal protection of important information with H.264 NAL video features. Simulation results show that HMP can achieve good perceptual picture quality for H.264 video under packet-loss network conditions.更多还原
