Hi,
I found a schematic for S-Video to Composite, and it works fine, but,
I want to split up the Composite into S-Video. Is it possible, and if
so, what do I need to make it happen? Thanks, Bill Garber from
GS-Electronics http://www.garberstreet.com

Unfortunately it's not so easy. Combining the parts of an S-Video
signal to produce a composite signal is just a few resistors, but
taking it apart again requires some filtering. You need a band pass
filter to peel off the chrominance and a band stop filter to remove the
chrominance from the luminance.

Much better to buy one. http://www.datapro.net/techinfo/CSV-900.html

Be aware that even when you have taken a composite signal apart you
will not get the S-Video quality as the cross-colour and
cross-luminance components will still be present.
