Abstract:
1. A communications apparatus comprising: an interface for receiving from a communications network at least first and second signals in a first frequency band, the first signals containing programming material and occupying part of the first frequency band; a tunable bandpass filter coupled to said interface for passing signals in a first frequency sub-band, said first frequency sub-band being a portion of said first frequency band; a frequency translator device coupled to said tunable bandpass filter for translating one or more second signals from the first frequency sub-band to a portion of a second frequency band; a mechanism for converting the first signals to third signals, the third signals occupying the first frequency band in its entirety, wherein the third signals contain the same programming material as the first signals; a tunable stop-band filter coupled to said interface for blocking frequencies in said portion of the second frequency band to which said frequency translator device translates said one or more second signals; and a combiner coupled to said mechanism for converting the first signals to third signals, said frequency translator device, and said tunable stop-band filter for combining signals generated by said frequency translator and signals passed by said tunable stop-filter.
