[sci.electronics] VGA to Sync-On-Green interface circuit

Could someone refer me to a good reference on video interfacing circuits?
(Especially one that spans the analog/TV/broadcast and the computer realms.)

I've looked at the standard specs for an RS-170 (?) video signal,
but haven't had any luck combining the H and V syncs (TTL) with the
analog video signal to produce an appropriate signal for an old CAD monitor.

My first inclination was to track down the output of the sync-extractor
and inject the H and V signals directly, but that was stymied by lack of
schematics (though not for lack of trying).  If it wasn't a large-screen
monitor I wouldn't bother...

thx, k(sup)2

Although it's old, Lancaster's book is a classic.  A newer edition
may perhaps be available by now.
