Help needed
Does anyone have a simple PIC / video sync / genlock circuit for on screen
display or video overlay of some small graphics and text overlaid on NTSC
video or (RS-170). There are commercial IC's from Maxim, ST micro, TI, but
most are obsolete. I know this can be done, just need the source code and
schematics, any help appreciated.

IIRC, that device is quite expensive. If you can live with pretty bad
resolution, look up something called pictock.
