发明名称 NARROW BANDWIDTH SIGNAL DELIVERY SYSTEM
摘要 A bandwidth-limited system for delivering satellite video signals. The system comprises a receive antenna that includes at least one low noise block amplifier (LNB), and a module, coupled to and proximate the receive antenna, the module comprising a multiswitch, coupled to the LNB, for directing the satellite signal received by the LNB to an output of the multiswitch a tuner, coupled to the output of the multiswitch, for tuning to a specific portion of the satellite signal, the specific portion of the satellite signal selected based on commands received from a new Integrated Receiver Decoder (IRD), a demodulator, coupled to the tuner, for demodulating the specific portion of the signal into a plurality of demodulated signals, and an interface for delivering a specific demodulated signal to the new IRD, wherein the specific demodulated signal is selected based on the commands received from the new IRD, and the commands and the demodulated signal are carried on a single connection between the at least one IRD and the interface.
