Abstract:
A frequency translation module for delivering satellite signals to Integrated Receiver Decoders (IRDs). The module comprises at least one input for receiving polarized satellite signals, wherein at least one input is coupled to at least one low noise block amplifier (LNB), at least one legacy output, the legacy output coupled to the input through a multiswitch, wherein each legacy output selects a polarization of a satellite signal based on a Legacy IRD command directly to the multiswitch, and at least one combined output, the combined output coupled to the multiswitch through an interface, wherein at least one new IRD selectively commands the frequency translation module such that each new IRD receives a portion of a satellite signal based on commands received from each IRD.
