Distributed Violin Duet

On November 9, 2001, a violin duet was performed over a wide area, high speed computer network in full-screen video as part of the RISQ 2001 Conference. To our knowledge, this marked the world's first demonstration of such a high quality and low-latency system, using internet protocol communications.

Although separated by several kilometres, the two performers were able to hear each other in "near-real-time," (approximately 20 ms delay) allowing them to synchronize their playing as if standing together on the same stage. A one-way video transmission from accompanied the audio -- problems with the second video card prevented this from being a bi-directional video demonstration.
