I heard a rumor that someone demoed a system at xhibition that featured a window that displayed a real-time video signal. Does anyone have information about this? What sort of special hardware/software is required. Please repond directly to me. Thanks, Rob Hagens UW Madison Computer Science Dept.

It was Parallax that was demoing the live video system. The system uses Interactive Systems' 386/ix operating system with Interactive's X11 server which has specific extensions for the live video. The current "video card" that drives the monitor and accepts the video signal is actually a box with its own power supply that sits on top of the 386 pc and costs about $8000. So its really a video processing system with a 386 cpu as a peripheral. There is also a VME bus version of this (4 board set), but I don't know of any other servers which have the live video enhancements. devon@SSD.HARRIS.COM

Parallax Graphics (2500 Condensa St, Santa Clara, CA 408-727-2220) also makes 1280 graphics processors (with video) for the Qbus (Vax) and there are servers on the IBM RT (ACIS) and Vax (Ultrix) as well as the Sun/VME and 386 boxes you mention. The system with X is in use at MIT Project Athena and here at Bellcore, and has been shown at SIGGraph as well. There is a group putting together an X protocol extension for video. Parallax also does NEWS. [I am not a spokesman for any of these organizations -- just a PSA.] Eleazor bar Shimon, once and future Carolingian yba@sabre.bellcore.com

(or Boing Inc. or whatever) was at the Xhibition demonstrating X11 for the Amiga. One of his systems had the genlock attachment and was running live video underneath the root window. This was pretty amusing as his booth was right next to the one Parallax had.
