  • a multiswitch, each input of the multiswitch receiving a satellite signal;

    a plurality of tuners, each tuner coupled to a frequency translation module output of the multiswitch, wherein each tuner accepts the satellite signal and tunes to a specific frequency band of the satellite signal to deliver a selected transponder signal, each tuner receiving commands based on tuner commands from at least one Integrated Receiver Decoder (IRD);

    a plurality of demodulators, coupled to the plurality of tuners in a respective fashion, for demodulating the selected transponder signal into a plurality of demodulated signals, each demodulated signal comprising a plurality of packets; and

    an interface for delivering the demodulated signals to the at least one IRD, wherein at least the demodulated signals and the tuner commands are carried on a single connection between the at least one IRD and the interface.
