A PC-based video conferencing system for a virtual seminar room is presented. The platform is enhanced with DSPs for audio and video coding and processing. A microphone array is used to facilitate audio based speaker tracking, which is used for adaptive beam-forming and automatic camera-control. Recently the system was demonstrated between two geographically separated universities in Denmark. The communication was based on the use of UDP/IP. Results are reported and an overview of the system is given.
