2. Introduction
2.1 Description
S-Video is a form of video found on most consumergrade VCRs, camcorders, and televisions. It is also a
video output on some PC video cards. S-Video is made
up of the Luminance component (also known as “Y”)
and the Chrominance component (also known as “C”).
S-Video can normally be run only over 50 feet or so of
S-Video Cable before the signal degrades so badly that
it’s of little use. To run S-Video over a longer distance
(as is common), you can put the components that make
up S-Video on two separate co-axial cables. To do this,
use the S-Video Breakout, a passive bi-directional
breakout device. Two models are available: The BNC
model lets you run your S-Video signal from one 4-pin
female mini-DIN connector to two 75-ohm BNC
connectors. The RCA model lets you run your S-Video
signal from one 4-pin female mini-DIN connector to
two gold RCA connectors.

3. Installation
NOTE
You must use two S-Video Breakouts to complete
installation (one at the S-Video source and one a
S-Video termination).
1. Connect your S-Video source’s output (VCR,
camcorder, distribution amplifier, etc.) to the
Breakout’s 4-pin female mini-DIN input.
2. Connect one coaxial cable to each output (the
connector type is determined by the breakout you
have). It is helpful to mark the cables as “Y” and
“C” respectively.
3. At the terminating end of the cable run, connect
the “Y” cable to the “Y” input connector and the
“C” cable to the “C” input connector.
4. Finally, connect an S-Video cable to the 4-pin
female mini-DIN.
