Amiga genlocks are Amiga specific. One of the features of the Amiga
computer is that you can feed an outside timing pulse into the computer
to synchronize the bus and video to an outside source. This makes it
easy to support genlocks.
This is an unusual hardware feature, and means that genlocks designed
for other computers have more work to do. I'm not really that
knowledgeable on the subject, but I believe that IBM clone genlocks
are usually built into video boards, so that you buy a all in one
VGA board and genlock (and perhaps frame grabber).
You actually may find it cheaper to buy an Amiga 500 and genlock than
to equip your clone with one. (Again, I'm not very knowledgeable
here, I just seem to remember seeing ads for clone genlocks that cost
about $1000).
Perhaps other folks in this notesfile can make recommendations for
IBM clone genlocks, or at least recommend features found in Amiga
genlocks that you should add to your feature list.
By the way, your note asked about two very different capabilities. Being
able to overlay computer graphics on a video source is genlocking. Being
able to digitize a video signal so that it can be stored and manipulated
by the computer is frame grabbing. In the Amiga world, these usually
are different products, but not always. For example, the video toaster
and some of the other high end video cards perform both functions (as
well as others). When shopping for the card(s) you want for your clone,
make sure that you get both features if you want both features.
