Hmm, I picked up an old VGA downscaler from an old plasma TV (got to love electronics junk bins). I was going to just reverse engineer it a bit and harvest the parts (it sports some very nice nichicon capacitors), however if we have fun things like this as an option I might have to look into actually doing something with it.

That's a pretty cool project. I've been trying to buy s-video cables for everything, but it just doesn't make that big of a difference. Keep it up!

S-video was great, I was using that for almost everything from SNES up until I got an HDTV with no S-video (damn cheaping out). I mean, I've never had RGB to compare it to, but looking at S-video vs 480i component, I agree with whoever it was way up in the thread that said the jump between them was less significant than the jump between composite and S-video. Which itself was generally not as significant as going from rf to composite. Man, rf was the worst.

Not exactly. Sync pulses happen between the lines of the image, so they can be mixed onto any channel losslessly. Component and S-Video mix it on Y, on RGB you can mix it onto the green channel. SCART does not do so, though, it uses the dedicated composite line to carry the sync pulses, often as part of a complete composite signal.

I forgot about that. PS2 moves sync to green, when running games at 480p or above, technically fixing the issue.
But I'm not aware of a TV who supports sync on green RGB from RCA jacks.

Relevant, I'm lazily working on building this, supposed to very nicely convert RGB to YUV (usable on almost all Component inputs). Supposed to be a lot nicer than S-Video, obviously straight RGB would be the way to go but that's not feasible for most people.

Edit - would help if I provided the schematic. http://i.imgur.com/kei1oan.png

Edit 2 - also, source thread, some absolutely phenomenal information in all of it. http://www.sega-16.com/forum/showth...Component-converter-design-using-the-BA7230LS
Nice, I may give this a go also.

edit: Well I've now ordered everything needed, I'll be installing this on a genesis, maybe also a snes since I ordered enough to make 2-3 :grog:
