An identification of correlation between network QoS and video quality index for IPTV service

Importance of perceptual quality has arisen as one of the major issues to successfully deploy IPTV services. Therefore, guaranteeing a certain level of network QoS is well and widely understood, but it is much more important to notice perceptual quality as perceived by the user. In this paper, we seek to identify relationship between video quality index and network QoS parameters so that we can ultimately figure out video QoE assessments with network QoS for IPTV service. We conduct simulations for seeking the impact of networking events on perceptual quality and how the events are correlated with video artifacts.
