Multimedia streams have increased dramatically over the wireless networks during the last few years. 3D video stream-based applications and movies will become significant contents of wireless network traffic in future Internet. This paper shows Quality of Experience (QoE) results based on transport network's Quality of Service (QoS) level degradation obtained from subjective tests which were carried out for 3D stereoscopic video files transporting through GPON-based transport network combined with IEEE802.11n standard based WiFi sub-networks on clients' side. Gathered information show that QoE level is influenced with more factors like: bandwidth limitation or channel interference in WiFi network and QoS parameters' values of transport network as well. In case of 3D contents quality of film shooting, size and resolution value of using display also take effect on perceived visual quality. Evaluation results were processed statistically IBM SPSS Statistics software-package.
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. Characterizing the necessary Quality of Service requirements is hard, since only a few empirical results are known about the user perceived 3D quality. In this paper a statistical analysis of subjective perception of 3D stereoscopic video Quality of Experience (QoE) are investigated with respect to network level QoS. The network is configured to demonstrate a real environment; thus, GPON-based aggregation is used. Our results show characteristics of QoE-QoS relationship in the case of 3D video playback. We also tackle the challenge by carrying out GPON-based transport network with IEEE802.11n standard based WiFi access measurements focusing the QoE of 3D content. And according to our results we propose cubic fitting function for modeling QoE-QoS relationship in the case of throughput degradation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
