It means to take two video signals and combine them into a single image,
possibly using one of the two as a "time base" against which to correct
the other.

Give such a device a PAL signal and an NTSC signal, for example, and the
Genlock will decide which of the two to use as it's time base, and combine
the two streams into one output, at whatever synch rates it chose based on
it's inputs.

It's also possible that the Genlock could be generating it's own synch
signals, combining both video inputs into one, at the chosen time base.
