Network Packet Level Based Video Quality Assessment Metric

The paper analysis the influence of the network packet on the video transmission quality, i.e. video transmission quality, the specific performance of packet loss and jitter. For packet loss, this paper analyzes the packet loss rate, packet loss and loss affects the length of the video packet type, the use of linear neural network evaluation model, for jitter, mainly with the jitter buffer size for the normalization process, and then together with the video bit rate as a parameter, the use of BP neural network evaluation model. Finally, the establishment of a transport network simulation platform, WANem WAN simulator simulates network packet loss and jitter phenomenon occurs simultaneously video transmission quality evaluation model, due to the influence of nonlinear parameters for video, still use BP neural network algorithm, models better, with some reference value.
