Question

What is a s-video cable, and what does it do??

Answer 1

Short answer is that it carries video signal.

Longer answer is that s-video is a cable standard to carry an analog video signal with separate chrominance (color) and luminance (intensity) lines.  It is generally considered "better" than composite (standard "RCA video") but not as good as component video.  All of these are analog standards and should not be confused with digital standards such as HDMI and DVI.

In general order of best to worst:

HDMI/DVI

Component (RGB or YPbPr)

S-Video

Composite ("yellow RCA")
