1. A broadcast method comprising:transmitting, via one or more broadcast transmitters, a broadcast signal over a desired radiofrequency (RF) band, wherein the broadcast signal comprises encoded broadcast media content and encoded return channel information;
transmitting, via the one or more broadcast transmitters, a beacon signal to a receiver, and the beacon signal identifies one or more modifications to a center frequency, a bandwidth, or a modulation type of the broadcast signal transmission that will be subsequently implemented in a modified broadcast signal;
transmitting, via the one or more broadcast transmitters, the modified broadcast signal over the desired RF band, wherein the modified broadcast signal is in accordance with the one or more modifications;
transmitting, via the broadcast signal and the one or more broadcast transmitters, the encoded return channel information, wherein the encoded return channel information indicates a return channel;
transmitting a return channel window, a portion of a spectrum, or both, via the one or more broadcast transmitters, to be used by the receiver for the return channel for interaction with the broadcast media content, wherein the portion of the spectrum is based at least in part upon the beacon signal, and wherein the return channel window is spaced apart from another return channel window by a delay; and
receiving a return signal via the return channel during the return channel window, over the portion of the spectrum, or both.
