Packet Loss Pattern and Parametric Video Quality Model for IPTV

This paper proposes a packet-layer parametric quality of experience (QoE) oriented model for IPTV service over next generation communication system. It is a model that based on the ITU-T G.1070 video quality model, whose video quality parameters can be adjusted for IPTV applications. In the paper, three metrics for evaluation of the packet loss burst are introduced for the enhancement of ITU G.1070 model. The experiment results show that the proposed model, T-model, correlates quite well with subjective opinion of IPTV video quality, and the results also prove that T-model, by considering packet loss pattern of the network, is more accurate for estimate of the video quality than standard ITU-T G.1070 video model.
