<chomp> A while ago I posted a query to the net regarding driving the RGB input of my pc monitor from the composite output of my VCR. There were a few requests to summarize the results to the net. Follows is the only response I got. >What you need is a subset of any color TV, since broadcasts >are composite and ALL color CRTs are RGB. >You need a little box containing a chroma demodulator IC >and a "matrix" of resistors (usually part of the IC these >days) and a DC power source for it. You'd think by now >somebody would sell such a beast. Look for it; >you'll get a hell of a picture! mike k I asked an analog hack what the previous meant and then did some looking around... couldn't find a chip that had the matrix onboard but there are plenty of chroma demodulators. Unfortunately it doesn't look like it is quite as easy as wiring up a digital clock (my only ever piece of hardware experience). Anyway, does anyone out there in net land have any further comments on this? Is there such a box ready made? How about even a schematic? Some of the app notes associated with the chips I looked at seemed to indicate that just the chip and a DC supply wouldn't quite be adequate to do the job. Any ideas? thanks in advance... ... uw-beaver!{tikal, teltone} david m chinn !{tikal,teltone} box 2249 !dataio!butler!chinn kirkland, wash 98083
