Improving Fairness in QoS and QoE domains for Adaptive Video Streaming

Authors:
Bjørn J. Villa
Poul E. Heegaard

Keywords: Video Streaming; Fairness; QoE/QoS

Abstract:
This paper presents an enhancement to a category of Adaptive Video Streaming solutions aimed at improving both Quality of Service (QoS) and Quality of Experience (QoE). The specific solution used as baseline for the work is the Smooth Streaming framework from Microsoft. The presented enhancement relates to the rate adaptation scheme used, and suggests applying a stochastic or fixed/unique setting of the rate adjustment intervals rather than the default fixed/equal approach. The main novelty of the paper is the simultaneous study of both network oriented fairness in the QoS domain and perception based fairness from the QoE domain, when introducing the suggested mechanism. The method used for this study is by means of simulations, measurements and numerical optimization. Perception based fairness is suggested as an objective QoE metric which, requires no reference to original content. The results show that the suggested enhancement has potential of improving fairness in the QoS domain, while maintaining perception based fairness in the QoE domain.
