This paper presents a bandwidth sharing scheme for group video conferencing. The key features of the scheme are the monitoring of implicit user-hints and message passing, which are used by each client in order to identify and report their interest in other group members. Information about user interest is then used by each video sender in order to adjust their frame-rate, resolution, and ultimately bandwidth consumption in an attempt to satisfy the current interests of the receivers. A general framework and initial prototype are presented together with experimental results.
