基于IP网络的视频传输质量评测方法的实现
首发时间:2009-02-26
摘要:IP电视业务是IP网络上发展出来的新兴业务,它提供组播、点播等视频功能,而且结合通讯技术,使用户互动地参与视频节目。本文对IP视频传输的相关协议和MDI(Media Delivery Index)媒体传输质量指标进行了解析,并详细介绍了在实际应用中计算Delay Factor和Media Loss Rate的实现方法。实验结果证明了方法的有效性。为研发基于MDI的网络视频传输监测系统提供了理论基础。

A Realization of Video over IP Quality Measuring Method
Abstract:Video over IP is a new network value-added service developed with IP network, which provides linear broadcast and video on demand services, with the communication technology, users could interact with the TV programs. This paper interprets the relative protocols of video on IP, and explains the theory of MDI, a realization of how to compute Delay Factor and Media Loss Rate is also given. This method has been shown to be effective by the experiment. The foundation of developing a video on IP quality monitoring system has been provides.
