S-Video basically is component video (right audio, left audio, yellow video), at least in Australian PAL-land. S-Video is all 2*3=6 wires in one cable, rather than three. Because of this, it's supposedly slightly better quality.

I'm sorry, but I have a hard time following this line of logic.

Analog monitors are basically RGB, right? Well, if I want to carry a video signal a long way from a computer to a monitor (we have to do this in a few places at work) I'll use a distribution amplifier to boost the signal, then I'll adapt the VGA cable (all signal wires in one cable) to a five-wire, or RGBHV, cable. This separates the R, G, B signals, and carries two separate sync signals (horizontal and vertical), each in a separate cable. It is much thicker, insulated, and carries the signal a lot better over a distance.

What would lead you to believe that you'd get a higher level of quality by putting the signals together???

For example, see this thread.

Unfortunately, every single fact here is false (except maybe that Australia uses PAL).

  • S-Video is a composite signal that has b/w (luminance, sync, blanking) on one pair and the color carrier on another pair (core).
  • This makes it better than traditional composite, in that there is no aliasing between the color carrier and the b/w signal. This allows better color bandwidth and less interference between color and fine structures in the b/w (which, in turn, allows better b/w bandwidth).
  • It is significantly worse than RGB or component (YPbPr), as the color information is still being crammed into the color carrier.
  • There is no audio involved. This is on a separate cable (set of cables).
  • Hence, S-Video is 2-core (two coax lines, one for b/w and one for the color carrier).
  • If you combine the two signals (by shorting them together, in a severe pinch, or preferable capacitor-coupling the color carrier), you get back the traditional composite signal ("yellow video", which is *not* component video).
