Analysis of the relationship between quality of experience and service attributes for 3D future internet multimedia

Abstract

Provisioning 3D video stream-based services online in an acceptable quality, even in a wireless access environment, is a big challenge for Future Internet service providers. Only few empirical results are known about the user perceived quality of these kinds of services. In this paper we describe a statistical analysis of the relationship between Quality of Experience and service attributes for active 3D live streaming, which was carried out in a real home scenario via an IEEE 802.11n standard based Wi-Fi access available for transferring data at the customer side. 90 participants took part in this investigation who watched 20 test cases of the full reference based subjective quality test suffering Quality of Service degradations, Wi-Fi TX-Power value changing and existence of secure and not secure (i.e., with and without IPsec) 3D video delivery. QoE was also affected by human factors like acceptance rate of 3D technology by the participants and their prior technical knowledge and experience, which could cause dissonant states of cognitions. The investigation presented here could help in the design of future QoE-aware 3D video streaming systems.
