End-to-end video quality analysis and modeling for video streaming over IP network

We derive an analytical end-to-end video quality prediction and control model for video streaming over an IP network. This model maps the quality of service (QoS) parameters defined at the connection level to actual video presentation quality at the receiver end. Specifically, we provide an analysis on the effects of packet loss on the decoded video quality and relate the packet loss ratio, one of the most important QoS parameters at the connection level, to the actual video quality. The model also characterizes the rate-distortion (R-D) behavior of the encoder at the video sequence level, predicting the average encoding quality for a given channel bandwidth. Our experimental results demonstrate the accuracy of the proposed video quality model.
