Very true! Oscillators cover a range of different configurations. Not just sine wave types. Scanning waveforms are basically generated by charging a capacitor and rapidly discharging it once a certain voltage is reached. This process can free run but in a television the discharge is triggered by the synch pulses taken from the received signal.
