# Composite video encoder

You use this information at your own risk.

This document contains the schematic (as drawn by Bruce Abbott), of the composite video encoder used by Amstrad in their MP1 modulator/power supply for the CPC464.

This circuit can generate a composite video signal, from the Amstrad's RGB video output suitable for the aerial input of a television.

In Bruce's own words: "The colour produced by this curcuit is a bit smeary, due to not having a luminance delay line. It uses the Motorola MC1377 encoder chip."
