Conversion of RGB to Composite signal can be done with a small amount of
circuitry.  I think there are IC chips that do most of the work.  You have
to construct luminance and chroma signals, which is just matrixing with
resistors, and then modulate the chroma signal on a 3.57945-MHz color
subcarrier and add it to the luminance to get the composite.  Or something
like that.  (I can get exact details for you if you wish.)
