The room has the following physical characteristics:
The room is painted in "white dove eggshell" paint manufactured by Benjamin Moore.
Two computers, one Sun and one PC, are placed in the podium desk for projecting slides and viewing network participants. Another Sun and PC control the booth hardware and digitize and encode the audio and video signals.
The podium console (lectern) has space for
Our console was custom-made by Hogg's Cabinet Shop (contact: Bill Dillon; 717.529.2522; fax: 717 529 6637), but there are off-the-shelf versions as well, including Nova, ($2200) or Mediatech Smart Lectern, KSI, SMARTdesk.
Presentations can be captured by an overhead camera, from an electronic whiteboard, from regular whiteboards, from transparencies via a light-box or through a scan converter.
All video signals are carried as Y/C (S-Video) for improved clarity, particularly when using the scan converter. A minimum resolution of 450 vertical lines is maintained throughout. CVN still uses composite video. A converter translates between the two formats.
Instead of a scan converter, it may be advantageous to use a graphics card with built-in NTSC output.
We use a fiber-optic security system manufactured by LightGuardian (see also Minatronics).
