There is a nice chip recently introduced by Motorola which will convert
RGB analog into composite video for you.  It takes the video
at 1.0V p-p, with a 10K input impedence, and a sync signal, and
produces composite output, either PAL or NTSC, depending on the
crystal you use, and a strap.  The part number is MC1377, and I
think that it's only a couple of bucks.  The data sheet I have
includes the application circuit, as well as one showing an interface
to an RF modulator.  Sooooo, if you can get it from digital to
analog RGB, this will get it to composite.
