An Impact of Packet Loss Locations on QoE in IPTV Services

There have been much of works on the impact of QoS parameters such as packet loss, etc on the user perceived quality. However, the perceived video quality may vary according to the location of packet losses rather than the degree of packet losses in IPTV services. In this paper, we analyzed the impact of packet loss locations and patterns on the user perceived video quality. For the experiment, we made test sequences by applying the domestic standard for IPTV services. And, we used the two international standards such as DSCQS and ACR for the evaluation of subjective quality.
