QoE Assessment for Broadcast Audio Contribution over IP (ACIP)

Broadcasters will increasingly use audio contribution over Internet protocol (ACIP). So far, no dedicated Quality of Experience (QoE) prediction framework exists. In this paper, we present a novel non-intrusive parametric QoE rating framework for such a professional broadband audio communication using Voice over IP (VoIP) technology, based on the extended E-model for telephone networks (ITU-T Rec. G.107). For this, we propose an R-factor scale extension to a maximum value of 157, instead of 129 as is used for wideband. Finally, our QoE rating model provides separated impairment factors for the delay, loss, coding and bandwidth impairment. The model was developed based on our proposal for instrumental evaluation as well as subjective experience by experts.
