We used two servers in our testbed: A 1.4-GHz Pentium 3 computer with 1 GB of RAM was our Web and streaming-media server, and a Dell PowerEdge 1650 with a 1.14-GHz Pentium 3 and 2 GB of RAM was used for video encoding and webcast management.
We ran Microsoft Windows 2000 Server SP4 with IIS and Windows Media Services enabled on the Web and streaming-media server. The second server ran Windows 2000 Advanced Server SP4. We used an Osprey 540 video-capture card and a Panasonic PV-DV952D digital camera. Our clients ran Windows 2000 Workstation with IE 6. Our camera, a standard consumer-class mini-DV unit, had Firewire, S-Video and RCA A/V outputs. We used Firewire and RCA when applicable.
We filmed one presenter in our Syracuse University Real-World Labs and included a 26-slide PowerPoint presentation filled with text and graphics in various sizes. We used a combination of audio and visual hand signals to note when a change-slide event occurred to verify video/PowerPoint synchronization.
