S-Video signals are generally of higher quality than analog composite video
signals. Composite video signals combine the black and white (monochrome)
signals together with color information on a single coaxial cable. S-Video
signals, however, use two signal wires to keep the luminance (black and white)
and chrominance (color information) signals separated.
CONNECTOR TYPE
. . . . . . . . . AND PINOUTS
Quadra uses the standard 4-pin mini-DIN connector allowing the use of
standard, commercially available cables. The pinout for the standard S-Video
connector is shown in the figure below:

The 4-pin mini-DIN connector has the following signals:
S-VIDEO CABLE
. . . . . . . . . LENGTH
S-Video cables tend to have higher loss than the standard coaxial cables (that
are used for composite video). Therefore, for best results, cable lengths should
be kept to a minimum. S-Video cables are available commercially.
