Video signals contain horizontal and vertical sync pulses. In an NTSC signal, the vertical sync pulses are around 60 Hz, and they are of a higher amplitude than the signal, contributing a significant 60 Hz component in the frequency domain.

The horizontal sync pulses, typically at 15750 Hz, also contribute to the spectrum.
