【摘要】 随着无线通信技术的发展,大屏智能手机的普及,越来越多用户喜欢在手机上用客户端在线观看网络视频,因此对用户视频体验的研究就显得尤为重要。初始缓冲时延和视频播放过程中的卡顿占比是移动用户在视频体验上的两个关键指标。研究了这两个关键指标与网络侧变量之间的函数模型,并建立可以通过网络侧变量估计终端用户视频体验得分的回归决策树模型。更多还原

【Abstract】 With the developmentof wireless communication technology, the popularity of large-screen smart phones, more and more users like to watch online video on the mobile phone, so the research on user video experience is particularly important. The initial buffer delay and the Catton ratio in the video playback process are the two key indicators of mobile users’ video experience. This paper studies the function model between these two key indexes and the network side variables, and establishes a regression decision tree model which can estimate the end-user video experience score by the network side variables.更多还原
