For S Video the normal "Composite" video signal that contains.. frame & line
"Syncs" + the black & white "Luminance" Video + the "Chromanance" colour
signal, is split into 2 components:- Luminance & sync, & a Chromance.
The purpose of having 2 separated signals is to negate the need for filtering
which always comes with some definition loss, & to stop cross colour problems
caused by sharp edges & gratings in the Luminance Jamming the colour signal.
