| Research Abstract |
We have studied cross-layer control technologies for multimedia applications in NGN(Next Generation Network) in order to enhance and maximize QoE(Quality of Experience) explicitly. We have improved the efficiency of the video output scheme SCS. Also, in bandwidth guaranteed audiovisual IP communications, we have clarified the optimum bandwidth allocation between audio and video, and identified the optimum pair of the video encoding bit rate and the playout buffering time. Furthermore, we have proposed a QoE enhancement scheme for haptic-audiovisual communications.
