摘要:

本文提出了一种面向RTP视频流媒体的视频感知不等差错保护(ULP)系统,用于在突发丢包网络中保护RTP视频流。考虑到帧的相关性、信道状态以及保护比特流的比特率约束,我们的算法通过前向纠错(FEC)技术实时选择最合适的帧进行保护。该系统得益于一种明智的RTP封装方式,使其能够在帧级别工作,而无需除解析RTP头部之外的任何进一步处理。这使得我们的系统简单且快速,非常适合集成到商业视频流媒体服务器中。仿真结果表明,我们的技术优于其他已提出的ULP方案。

英文摘要:

A video-aware unequal loss protection (ULP) system for protecting RTP video streaming in bursty packet loss networks is proposed. Considering the relevance of the frame, the state of the channel, and the bitrate constraints of the protection bitstream, our algorithm selects in real time the most suitable frames to be protected through forward error protection (FEC) techniques. It benefits from a wise RTP encapsulation that allows working at a frame level without requiring any further process than that of parsing RTP headers. This makes our system straightforward and fast, perfectly suitable to be included in commercial video streaming servers. Simulation results show how our technique outperforms other proposed ULP schemes.
