Abstract

This paper presents results of an experiment in which plural video and voice streams transmitted over a network are output synchronously in networked virtual environments. We propose an adaptive QoS (quality of service) control scheme for video and voice traffic. According to the importance of each media object, CPU load and network load, the scheme adjusts the rendition rate of a 3D virtual space and the video resolution as well as the accuracy of media synchronization; also it can display a CG object instead of a less-important video object. In addition, the paper quantitatively examines the effect of the adaptive QoS control on the performance
