摘要: A method and computing device that provides a tunable RF filter for two-way communication system. The receives downstream video signal, filters the signal into at least one bandwidth band, each band related to desired upstream/downstream splits. performs an energy detection on determines lowest frequency of said contains content. sets diplex cutoff maximum upstream does not conflict with
