The NTSC decoder is probably the most complicated part of a color TV.
For those of you interested, Philips reportedly makes a single chip to
do this job, the TDA3563. I have no literature on this thing (yet), but
obviously something like it exists, or we would not have pocket color TVs
such as the Casio, which run off batteries.
