Modeling 3D video user experience forwireless networks

Abstract

Recently the entertainment industry, the multimedia content providers and the research community have been experiencing the decisive introduction and evolution of three-dimensional (3D) imaging. This far more complex and sophisticated than the traditional 2D technology raises the major problem of how users perceive quality of 3D video. This paper studies user experience for 3D video streaming that takes into account the spatial and temporal information of the video, the resolution, the quantization step size, as well as, wireless network related parameters from the physical, the data link and the network layers. The purpose of this study is to analyze the impact of each of these key performance indicators in order to efficiently model 3D video user experience in wireless networks. Such a model can be exploited by network selection algorithms so as to accurately predict user experience based on these indicators.
