摘　　要：手机视频业务与现有的互联网数据业务和语音业务相比,提出了对无线网络更高的要求。由于无线网络环境的复杂性,客观上很难长时间维持足够稳定的网络带宽,手机视频用户的视频实时播放质量会受到影响。因此实时监测到手机视频在各个环节的视频质量对于预警及用户投诉处理有相当重要的作用。本文根据手机视频业务的特点并深入分析手机视频流的特征,提出了手机视频质量监测技术和实现方法。设计视频质量监测分析系统可以实时分析手机视频业务的服务质量指标,同时根据网络的性能来判断业务质量受影响的程度,做到在用户的业务体验变差前及时发现问题,及时规避业务平台的可能出现瓶颈的问题,从运行维护和网络规划的角度确保手机视频业务的顺利发展和普及。Compared with the existing internet data and voice business,mobile video poses higher command for wireless network.Because of the complexity of wireless network environment,it is difficult to maintain sufficiently stable network bandwidth for a long time,thus adversely affecting the real-time broadcasting quality of mobile video users.Therefore,real-time surveillance of video quality in every link plays a key role in early warning and consumer complaint processing.This article analyzes characteristics of mobile video streams,and proposes technologies and realization methods of mobile video quality surveillance.The video quality surveillance analysis system analyses real-time QoS index of mobile video,and is able to detect problems before user experience worsens and avoid possible bottleneck problems in the business platform.This technology guarantees the smooth development and popularization of mobile video business from the perspective of operation and network planning.
