Try it, then tell us how well it worked with a low sample rate and a
slow processor.


You guys are so complicated... :-)

A pic12508 running on it's internal 4MHz clock + an lm1881 sync
separator does the job just fine.
There's no need to digitize the video information. You just have to
clamp the undesired signals to black level, you do this by counting
lines and syncing(sp?) to the vertical sync, this happens at most at
15625Hz for the pal people, slow enough for a pic. With a discrete
sync separator and running the pic at 10MHz you could skip the lm1881.
