S-video transmits the luminance and chroma portions of a composite video
signal separately. A lot of the artifacts visible on TV screens are due
to filtering stages that separate the chroma/luma signals. Assuming that
you have a high-quality source (a laserdisc player is one) you might get
a slightly better signal using a S-video rather than a composite cable.
Many people notice no difference.

S-video is not confined to any particular country, brand, or type of
video source.
