    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!

    There are 1 or 2 sources that do component on scart, most notably the Netgem freeview box. Some RPTV's can accept the signal on scart, I came across a Sony one that did. Otherwise, if you have one of these few sources, you get a scart-RGB on 3 or 4 phonos, and connect the appropriate ones. The YUV is on the actual RGB pins.

    S-video is a component signal Y/C but usually it is YUV/YPbPr that is reffered to as Component (RGsB, RGBS, and RGBHV are also flavours of component video) YUV/YPbPr is the norm and is based on the colous space which is different for RGB........signals
