1. An aerial surveillance apparatus for processing an analog video signal, the aerial surveillance apparatus comprising:

  • a first input configured to receive an analog video signal from a video camera;

    a processor coupled with the analog video signal and configured to filter and digitize the analog video signal to form a de-emphasized digital signal; and

    an output configured to couple to an FM video transmitter and to communicate the de-emphasized digital signal to the FM video transmitter, wherein;

    the filtering of the processor decreases amplitudes of higher frequencies within a band of frequencies more than amplitudes of lower frequencies within the band of frequencies, andthe FM video transmitter filters the de-emphasized digital signal using a pre-emphasis filter that counteracts the filtering of the de-emphasis filter.
