    Gee, when I used to be a tech in Video, Genlock was a box
that locked up on a master oscilator or any video source and
regenerated the H and V sync pulses for cameras and synced up
VTRs so you could do things like switching between sources
without loss of sync.  
     I think what you want is a frame grabber.  Some sort of
high speed A to D flash converter.
