AGC is Automatic gain control. where a proportional part of the amplified signal from the tuner etc is fed back to the tuner to maintain a constant gain. Flywheel sync was method used where the synchronisation of the TV which is locked by transmitted pulses could withstand noise and missing pulses. The oscillator worked like a flywheel maintaining a nearly constant speed and only requiring a percentage of the transmitted pulses to regulate its speed.
