摘要
对于HLS视频点播模型,定义了评价视频QoE的KPI.对于VoD这种包含用户播放行为的复杂应用场景,采用TCP流回播来分析视频的QoE.通过设计模拟包含跳播和回播的用户场景,进行仿真实验来评估出了视频点播的QoE情况.实验数据表明,该思路对于评估视频点播的QoE是有效的.
In this paper,the KPI for evaluating the video QoE is defined for the HLS video-ondemand model. For Vo D,a complex application scenario that includes user play behavior,TCP flows back to sow is used to analyze the QoE of video. By designing a simulation of user scenarios that include both jump and replay,simulation experiments are conducted to evaluate the QoE situation of video on demand. Experimental data show that this method is effective for evaluating QoE of video on demand.
