They are two related technologies, and there's nothing that keeps you
from implementing them both in one box. As Nate said, genlocking is
the process of combining two video signals -- in this case it's the
graphics generated by the computer together with a video source.
Chroma keying is when you replace areas of a certain colour with
another video source.
