A Packet-Layer Model with Content Characteristics for Video Quality Assessment of IPTV

Due to the lightweight measurement and no access to the media signal, the packet-layer video quality assessment model is highly preferable and utilized in the non-intrusive and in-service network applications. In this paper, a novel packet-layer model is proposed to monitor the video quality of Internet protocol television (IPTV). Apart from predicting the coding distortion by the compres‐ sion, the model highlights a novel loss-related scheme to predict the transmission distortion introduced by the packet loss, based on the structural decomposition of the video sequence, the development of temporal sensitivity function (TSF) simulating human visual perception, and the scalable incorporation of content characteristics. Experimental results demonstrate the performance improvement by comparing with existing models on cross-validation of various databases.
