Controlled vs. Uncontrolled Degradations of QoE: The Provisioning-Delivery Hysteresis in Case of Video
Responsible organisation
2010 (English)Conference paper (Refereed) Published
Abstract [en]

This paper applies the recently proposed provisioning-delivery hysteresis for Quality of Experience (QoE) to the case of video. The study is based on evaluations using the Structural Similarity Metric (SSIM) for different versions of a video in terms of resolution on one hand, and suffering from different packet loss ratios on the other hand. Upon translation of the SSIM into MOS, the QoE plotted versus the effective throughput shows the predicted behaviour: a controlled quality and throughput reduction leads to a better user perceived quality than the quality degradation due to packet loss. The results clearly quantify the necessity to control quality, instead of "getting hit" in an uncontrolled way.
