Abstract

This paper describes the architecture and protocols for integrating real-time audio and shared windows in computer-supported cooperative work (CSCW) environments. Such applications require that actions on shared windows be synchronized with accompanying audio. We give a characterization of this synchronization problem and propose an architecture for handling audio-enhanced cooperative work. We present a protocol for synchronizing the audio stream and window-event streams and evaluate its performance.
