摘要:
Methods and apparatus for frequency agile band-pass filtering of broadcast signals are disclosed. An example method to receive a broadcast signal for distribution to a plurality of reception sites disclosed herein comprises processing the broadcast signal with a frequency agile band-pass filter to receive the broadcast signal at a headend site for distribution to the plurality of reception sites, monitoring reception quality of the broadcast signal at an operating center separate from the headend site and included in the plurality of reception sites, and sending commands to the frequency agile band-pass filter from the operating center based on the monitored reception quality of the broadcast signal, the commands controlling at least a tuned operating frequency of and an attenuation provided by the frequency agile band-pass filter.
