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 adaption scheme used, and suggests applying a stochastic variable for the rate adjustment intervals rather than the fixed 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 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 great potential in improving QoE, while maintaining QoS.
