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.

Remote Mode

Local Mode

The incoming remote video signal (Pin 24) supplies all

synchronizing information. A discussion of the function of the

phase detectors helps to clarify the lockup method:

The MC1378 and a video system combine to provide a fully

synchronized standard signal source. In this case, composite sync

must be supplied by the video system or other time base system.

In the MC1378 the phase detectors operate as follows:

PD1

locks the internally counted–down 4 MHz horizontal VCO

to the incoming horizontal sync. It is fast acting, to follow

VCR source fluctuations.

PD1

locks the internally counted–down 4 MHz horizontal VCO

to a Horizontal Sync signal (at Pin 40) from the video

system (counted down from 36 MHz)

PD2

PD3

PD4

locks the 36 MHz clock VCO, which is divided down by

the video system, to the divided down horizontal VCO.

PD2

PD3

not used in LOCAL MODE.

is a gated phase detector which locks the 14 MHz crystal

oscillator, divided by 4, to the incoming color burst.

PD4

active, but providing an arbitrary phase shift setting

between the color oscillator and the output burst phase.

controls an internal phase shifter to assure that the

outgoing color burst is the same phase as incoming burst

at PD3.

PD5

locks the 36 MHz clock VCO (which is divided down by

the video system) to the 14 MHz (crystal) color oscillator.

The 14 MHz is, therefore, the system standard in LOCAL

MODE, and is not DC controlled.

PD5

not used in REMOTE MODE

Vertical lock is obtained by continuously resetting the sync

COMPOSITE VIDEO GENERATION

generator in the video system with separated vertical sync from the

MC1378, Pin 38. This signal is TTL level vertical block sync,

negative going. The horizontal sync from the video system to Pin 40

is also TTL level with sync negative going. The local/remote switch,

Pin 1, is in local mode when grounded, remote mode when taken

to 5.0 V. The overlay control, Pin 25, has an analog characteristic,

centered about 1.0 V, which allows fading from local to remote.

The color encoding at the RGB signals is done exactly as in

the MC1377. Composite chroma is looped out at Pins 18 and 20

to allow the designer to choose band shaping. Luminance is

similarly brought out (Pins 17 and 22) to permit installation of

the appropriate delay.

Composite sync output, Pin 39, and burst gate output, Pin 5,

are provided for convenience only.
