Media synchronization between voice and movement of avatars in networked virtual environments

摘要

This paper studies media synchronization control between voice and movement of avatars constructed by computer graphics (CG) in networked virtual environments. For the control, we adopt the virtual-time rendering (VTR) media synchronization algorithm, which the authors previously proposed. In the VTR algorithm, we choose the voice as the master stream and the movement of an avatar as the slave stream. By carrying out an experiment in which we interactively move both arms of the avatar synchronously with the voice, we assess the media synchronization quality and demonstrate the effectiveness of the media synchronization control.
