Abstract

Abstract: The quality of experience for video files is significantly affected when packet loss occurs.A simulated transport test bed EvalVid is carried out to analyze the correlations.Then the mapping model between packet loss rate and QoE are established by regression analysis.This effective model is easy to operate.The model is correct and able to detect impact of the packet loss on user experience in real-time.

Key words: quality of experience, EvalVid, regression analysis, packet loss, mapping model

摘要： 网络传输过程中发生丢包会降低用户对视频的体验质量。使用EvalVid仿真传输测试床来深入分析丢包率及不同位置丢包对用户体验的影响，并根据回归分析法建立了映射模型。用户使用该模型可以很方便地得出用户的体验质量。经理论分析证明该模型正确、易于操作，可实时检测丢包对视频的影响。
