ABSTRACT:
A communication system and method of communicating signals to a plurality of different types of receivers is provided. The communication system includes at least one transmitter that transmits a high priority signal and a low priority signal that are hierarchically modulated and transmitted as a single frequency network. At least one satellite receives and re-transmits at least one of the high priority and low priority signals. At least one of the plurality of receivers include a processor that performs the steps of storing the hierarchically modulated signal, demodulating the high priority signal from the hierarchically modulated signal, decoding the demodulated high priority signal, re-encoding the high priority signal, and processing the stored hierarchically modulated signal based upon the re-encoded high priority signal.
