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.
