This could be done without too much effort. Several manufacturers,
notably National Semiconductor and Philips, make single-chip sync
separators which are commonly used in TVs and monitors and such. I've
never designed a circuit around one, but I can't imagine them being too
However, with one of those chips probably running at least $10 or so,
I'd say $50 isn't all that bad.
