Internet2-scale Video Wall
Wouldn't it be nice if we can see all 200 members of the Internet2 simultaneously? This idea was inspired by Dr. Dixon's pioneering work on
the Megaconference.
However, instead of using H323 equipments, we will use VSee, a software system designed to transform wireless
laptops into secure high-end videoconferencing systems.
Two years ago, at the Computer Science Department at Stanford, we built a
30-stream video wall.
At the
Fall 2003 Internet2 meeting, we would like to demonstrate a video
wall showing 50 high quality videos. Each video will have a visual
quality comparable to a high-end Polycom.
The video wall consists of five laptops and portable
projectors. The figure below shows the video wall.
5 by 25 foot video wall
The first screen shows live videos from around the world: Iceland, Brazil,
Sweden, China, Canada, ... The second screen shows VSee's integrated PowerPoint
viewer. The third screen shows a 720x480 video feed from a DV camera.
The fourth and fifth screens show students streamed from Stanford.

The figure below illustrates the video wall equipment diagram.
The aggregate network load on Internet2 is 20Gbps in an
all-to-all connection (200 sites * 200 videos / site * 0.5 Mbps per
video).
