Abstract:
An automatic level controlled system for delivering satellite signals to at least one Integrated Receiver Decoder (IRD). The system includes a plurality of inputs, designed to receive a plurality of satellite signals, wherein the satellite signals are directed to the inputs based on an originating satellite for each of the satellite signals, an automatic level controller, coupled to the inputs, for adjusting a signal strength associated with each the satellite signals such that each of the signal strengths are within a predetermined range, a multiswitch, having a plurality of inputs and a plurality of outputs, wherein at least one input of the multiswitch is coupled to the automatic level controller, and an interface, wherein at least one of the outputs of the multiswitch provides a signal to the interface, such that at least one new IRD coupled to an output of the interface receives a portion of a satellite signal based on commands sent to the interface from the new IRD.
