Abstract:
1. A media broadcasting system comprising: a headend comprising a frequency agile band-pass filter to receive a media broadcast signal comprising a plurality of channels for distribution to a plurality of reception sites; and an operating center to monitor reception quality of at least some of the plurality of channels included in the media broadcast signal and to send a first set of commands over a communication network to the frequency agile band-pass filter to tune to and attenuate a first channel when the first channel is determined to be experiencing a degradation of reception quality determined to be caused by at least one of co-channel or adjacent channel interference, the operating center to remotely command a switch at the headend to replace a first output signal from a first receiver providing the first channel for distribution to the plurality of reception sites with a second output signal from a second receiver processing an output of the frequency agile band-pass filter, the operating center to send a subsequent second set of commands over the communication network to the frequency agile band-pass filter to override attenuation processing invoked by the first set of commands and cause the attenuation processing by the frequency agile band-pass filter to be bypassed to receive the first channel when the degradation of reception quality is further determined to be caused by fading in addition to the at least one of co-channel or adjacent channel interference.
