QoE-oriented resource management strategy by considering user preference for video content

Abstract

The user's Quality of Experience (QoE) is an assessment of the human experience. It's not only influenced by Quality of Service (QoS) parameters but also influenced by user's preference for video content. This article studies user's preference for video content and how user's QoE changes on account of their biases. Through two experiments, it is concluded that the higher the user's preference score is, the higher the user rate MOS and the less MOS reduces when the resolution of video decrease. That is, the more user likes the video content, the more tolerant they will be to quality reduction of videos. Then a network resource management strategy is proposed based on the conclusion, and a web site platform is established for the test. Eventually we get the result that 87.0% of the participants have their MOS value increased after using the strategy.
