Thanks to those who have taken the time to explain RGB video output to me! I still don't understand as much as I would like, but (excuse the following...) I'm trying to find out if it is possible to send an RGB (1K x 1K interlaced, 60Hz) signal to distances of up to 2 kilometers. People have suggested fiber optics--is this because none of us understand it or is there an existing technology? I've called Black Box and was told the only thing they do with fiber optics is RS232. Where to next? Thanks. -- John Campbell ...!arizona!naucse!jdc unix? Sure send me a dozen, all different colors.

Yes -- the technology exists to transmit RKB at your rates your required distance. There's a place in Massachusetts that specializes in 3270 multiplexors and link extenders, and their video grew from that. I once evaluated this technique for a former customer, and we transmitted 1280 x 1024 x 256 over about a mile in test. No problem. I believe they also had enough bandwidth to piggyback 2 channels of 19,2 kbps serial digital, for mice & digitizers, etc. The name escapes me -- something like Abel (?). (My references are at another site...) But the upshot is yes, fiber is the hot setup for this application and it has been shipping for at least 18 months.
