Abstract:
1. A method for filtering signals in a transmission medium having network signals coexisting with broadcast signals, comprising: (a) a filter control module controlling a filter coupled to a tuner, the filter switchably attenuating network and broadcast signals above a first frequency or network and broadcast signals above a second frequency greater than the first frequency; (b) the filter control module receiving an indication that the tuner will tune to a broadcast signal channel between the first frequency and the second frequency; and (c) the filter control module controlling the filter to switch to attenuating signals above the second frequency in response to receiving the indication; wherein the transmission medium is coaxial cable; the first frequency is an upper frequency bound for a first cable television broadcast system and the second frequency is an upper frequency bound for a second cable television broadcast system; and the frequency range between the first frequency and the second frequency overlaps with at least one MoCA channel.
