A Study on Architectures for Multimedia Multidimensional QoE Control

点击翻译按钮获取中文摘要

This study has made multidimensional quantitative assessment of QoE (Quality of Experience) in audiovisual-haptic interactive IP communications as well as audiovisual ones. It has also done fundamental researches on network architectures that enable QoE enhancement/guarantee. Furthermore, we designed and implemented a multidimensional QoE monitoring system with QoE estimation in real time. In addition, we investigated methods for QoE enhancement of the QoE-based video output scheme SCS (Switching between error Concealment and frame Skipping) in audiovisual communications. An idea of user-assisted management of QoE has been proposed, and it has been implemented in audiovisual interactive communications as an adaptive playout buffering scheme with GUI which achieves high QoE.
