You can modulate any combination of vision polarity and AM/FM sound using intercarrier methods. It's simple. Just modulate the sound on to the difference frequency between S and V carriers, then add it to the vision signal ready to be modulated on the RF carrier. It places more stringent linearity requirements on everything after the signals are added.
