Chrominance
S-video contains two separate components, luminance and chrominance (also
known as Y and C signals respectively). The luminance signal contains
brightness, intensity, and signal timing information. This signal contains all
picture information except for color. The chrominance signal contains only the
color information. You can see the complete black and white image, without
the chrominance, by only feeding the luminance signal into a monitor.

VIDEO (Composite)

Composite video is a type of video signal in which all information – the red,
green, and blue (horizontal and vertical sync) signals are mixed together.
