[Coco] Re: CoCo 3 to VGA

[Torsten Dittel]

Funny enough I had this idea of converting the CoCo3's RGB to VGA just a
few weeks before the discussion started here. I had a quick view on
what's on the market and how much this would cost. What I understand is
that there's a big interest in the beamer sector. People are using
VGA-beamers to produce high quality movie output from a video signal.
The problem with a video (e.g. TV) signal: there are two interlaced
pictures which leads (especially with movements in the picture) to some
effects you can see here

Most of the commercial SCANDOUBLERS have some "smart" DSP algorithms for
both digitized full "half images" to produce a better picture. I think
we don't need such "intelligence" for the CoCo3. A simple LINEDOUBLER
would be enough. Still haven't found a cheap solution, but I will keep
looking for it.
