Abstract:
1. A method, comprising: receiving, by a system including a processor, by way of a first communications link, a down-converted satellite signal occupying a portion of an intermediate-frequency bandwidth; providing, by the system, the down-converted satellite signal to a decoder that decodes the down-converted satellite signal resulting in a decoded broadcast signal for distribution through a multimedia distribution network; receiving, by the system, by way of a second communications link, a redundant down-converted satellite signal occupying the portion of the intermediate-frequency bandwidth; detecting, by the system, for the first communications link, an unintended signal within the intermediate-frequency bandwidth; determining, by the system, for the unintended signal, an interfering signal; causing, by the system, the decoder to substitute the down-converted satellite signal with the redundant down converted satellite signal responsive to detecting that the interfering signal exceeds a threshold; and initiating, by the system, an alarm signal responsive to detecting the interfering signal exceeding the threshold.
