Could be but I like Corey's idea better. The above is a scan converter.
Corey does not convert the scan but has the computer produce the right
timings for television. His circuit just does "coordinate
transformation RGB->YPbPr and NTSC composite modulation (colorburst,
3.58MHz crystal, etc)".
This seems a better idea. Process the signal as little as possible.
That's what I thought. I'm happy with the results, but the
annoyance of getting everything right is definately beyond the scope of
what most people are willing to deal with. It was also pointed out to me
a few months ago that my circuit wasn't completely accurate. I use a
3.58Mhz crystal to generate the color subcarrier, but in reality it should
be line-locked to the horizontal sweep frequency. That's one of the
modifications I'd like to do (with all my free time... hahaha!)
