1. A method for reducing power consumed by tuner operation, said method comprising:
- extracting, from an input signal, a first signal comprising a plurality of content channels and a second signal comprising a plurality of data channels;
transmitting said first signal to an in-band tuner operable to receive said first signal comprising a plurality of content channels and further operable to extract information from a selected content channel;
transmitting said second signal to an out-of-band tuner operable to receive said second signal comprising said plurality of data channels and further operable to extract information from a selected data channel; and
receiving said extracted second signal comprising said plurality of data channels at an amplifier, said amplifier operable to amplify said second signal and communicate said second signal to said out-of-band tuner.

Abstract
A method for processing an input signal is disclosed. The method includes receiving an input signal. The method also includes applying a first transfer function to the input signal to produce a first signal, wherein the first transfer function exhibits a high pass characteristic. The method further includes applying a second transfer function to the input signal to produce a second signal, the second transfer function exhibiting a low pass characteristic.
