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; and
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.

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.
