"For AC3, you must use a demodulator, because the signal from the player is (analog?)"

It's a digital signal embedded in an analog carrier. FM modulation is added so that it can be stored on the laserdisc. Thus, it must be demodulated for playback.

The modulators people by to connect a DVD player to a TV that only has a RF input do the opposite. It adds FM modulation (usually for channel 3 or 4) to the composite or S-Video signal so that the television can receive it.
