1. A method of detecting potential video traffic interference at a video head-end of a video distribution network, the method comprising:

  • detecting, at a video head-end, a signal populating an ultra high frequency (UHF) white space frequency;

    determining that a strength of the signal is equal to or greater than a threshold signal strength; and

    sending an alert from the video head-end to a network management system, wherein the alert indicates that the UHF white space frequency is populated by a signal having a potential to interfere with video traffic delivered via the video head-end.
