A Refined MDI Approach Based on Frame Classification for IPTV Video Quality Evaluation

Internet Protocol Television (IPTV) is defined as a digital television broadcast service through IP packets over broadband network. The acceptance from users can only be obtained and maintained by utter high video quality outperforming traditional TV which is based on cable or satellite technology. This paper proposes a refined measurement based on MDI (Media Delivery Index) which gives an indication of the real-time video quality perceived by the end users´ Quality of Experience (QoE). The refined Media Delivery Index (FC-MDI) takes Frame Classification into account to improve the performance of the MDI measurement. The results of experiments demonstrate that when two videos of different qualities have a same number of total dropped-packet, the traditional MDI measurement cannot tell the difference between them, while FC-MDI possesses a distinguishing feature.
