| 1. A signal distribution system for distributing a plurality of low noise amplifier and block converter (LNB) signals from a satellite outdoor unit (ODU) over a coaxial cable to an integrated receiver decoder (IRD) comprising: a signal selector that receives a plurality of broadband LNB signals comprising a plurality of transponder signals and digitizes the received broadband LNB signals, the signal selector is responsive to transponder select information transmitted by an IRD and selects a plurality of transponder signals in the digital domain from at least one broadband LNB signal based on the transponder select information;
a frequency translator coupled to the signal selector that is [capable of shifting] configured to shift the selected transponder signals to new carrier frequencies and a converter configured to convert the shifted selected transponder signals to produce RF signals; and
a signal combiner communicatively coupled to at least one frequency translator [capable of combining ], the combiner configured to combine at least two of the shifted selected RF signals to produce a composite signal;
wherein the modulation of the composite signal is the same as the modulation of the broadband LNB signals and wherein the composite signal is transmitted on the coaxial cable;
whereby the composite signal is transmitted to the IRD.
