Color Television Composite Video Overlay Synchronizer

The MC1378 is a bipolar composite video overlay encoder and microcomputer synchronizer. The MC1378 contains the complete encoder function of the MC1377, i.e., quadrature color modulators, RGB matrix, and blanking level clamps, plus a complete complement of synchronizers to lock
a microcomputer–based video source to any remote video source. The MC1378 can be used as a local system timing and encoding source, but it is most valuable when used to lock the microcomputer source to a remotely originated video signal.
