In this paper, the authors study the problem of video quality prediction over the wireless 4G network. Video transmission data is collected from a real 4G SCM test-bed for investigating factors that affect video quality. After feature transformation and selection on video and network parameters, video quality is predicted by solving as regression problem. Experimental results show that the dominated factor on video quality is the channel attenuation and video quality can be well estimated by their models with small errors.
