Looking at my SCART connections and cables, I see that SCART caters for RGB, and for composite, and also for 'Luminance' and 'Chrominance' (one pin for each). I thought Component was a three-wire system - luminance and two colour difference channels. So what is this? Is it two difference channels PAL-coded or something, but with Luminance kept separate? Is this something we should avoid? A related question ... can SCART cater for full component (YUV style)? I know it's only a piece of wire, so the question is really do kit manufacturers use SCART for this, or is YUV always on BNCs/RCAs? Yours, confused!
