Paper Abstract

The choice of the right coding method is a critical factor in the development process of mobile 3D television and video. Several coding methods are available and each of these is based on a different approach. These differences lead to method specific artefacts - content and bit rate are as well important parameters for the performance. In our study,w e evaluated Simulcast,Multi View Coding,Mixed Resolution Stereo Coding and Video + Depth Coding. Therefore each method has been optimized at a high and a low bit rate using parameters typical for mobile devices. The goal of the study was to get knowledge about the optimum codign method for mobile 3DTV,but also to get knowledge about the underlying rationale of quality perception. We used Open Profiling of Quality (OPQ) for comparison. OPQ combines quantitative rating and sensory profiling of the content. This allowed us to get a preference order of the coding methods and additional individual quality factors that were formed into a quality model. The results show that MVC and V+D outperform the other two approaches,but content itself is still an important factor.
