 Yes, I believe that is correct. The video is AM and the sound is FM. The colour carrier is quadrature amplitude modulated with a suppressed carrier. See Wiki for more details: http://en.wikipedia.org/wiki/NTSC

| TV was invented a very long time ago so they used AM modulation for the video luminance. Colour was added a lot later. Then stereo sound.
