ABSTRACT:
A method of processing an LNB power supply output signal comprising providing an LNB selection signal to select a first of the plurality of LNB signals as the input signal, superimposing a tone onto the LNB selection signal to select a second of the plurality of LNB signals as the input signal, providing a first transponder selection voltage to select a first set of transponders within the input signal, providing a second transponder selection voltage to select a second set of transponders within the input signal, and activating an adaptive load to preserve the tone if the second of the plurality of LNB signals is selected.
