Abstract

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