Patent ID: 7123875

Claim:
A satellite digital audio radio multipoint distribution system comprising: a satellite antenna for receiving a satellite digital audio radio signal; a terrestrial repeater connected to said antenna for decoding said satellite signal and recoding said signal into an XM radio terrestrial intermediate frequency (IF) multi-carrier modulated satellite radio terrestrial broadcast format signal, said repeater including: a receiver and demodulator for down-converting the satellite digital audio radio signal to a TDM bitstream, a de-interleaver and reformatter for re-ordering the TDM bitstream for a terrestrial waveform, a terrestrial waveform modulator coupled to said de-interleaver and reformatter, and means for recording the output of said modulator to an IF frequency; a system for distributing said recoded IF signal, and plural satellite digital audio radio service receivers adapted to receive said recoded IF signal from said distributing system and provide an audio or visual output signal in response thereto.
