The RGB Encoder (aka Video Encoder), straddling regions B4 and B5 of the jwdonal schematic
The RGB Encoder, as it is called in the official Super Nintendo development manual [1], converts analog RGB signals (pins 20, 21, and 22) from the Darlington triad to composite video output for Multi-Out. It also outputs to the RF Modulator.
