Abstract:
Example frequency agile band-pass filtering methods disclosed herein include monitoring reception quality of a media broadcast signal received at a headend including a frequency agile band-pass filter to receive the media broadcast signal, sending a first set of commands to cause the frequency agile band-pass filter to tune to and attenuate a first channel included in the media broadcast signal, the first set of commands being sent in response to determining that the first channel is experiencing a degradation of reception quality determined to be caused by a first type of channel interference, and sending 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 in response to determining that the degradation of reception quality is caused by fading in addition to the first type of channel interference.
