Abstract:
An apparatus comprising:a connector that is configured to connect said apparatus to an antenna device comprising an antenna capable of receiving a signal from a satellite;a tuner that is configured to receive a satellite signal from said connector and to perform tuning on the satellite signal;a demodulator that is configured to receive the tuned satellite signal from said tuner and to perform demodulation on the tuned satellite signal, thereby outputting a demodulated data stream, wherein the demodulation is performed in accordance with control by a computer;a forward error corrector that is configured to receive the demodulated data stream from said demodulator and to perform forward error correction on the demodulated data stream, thereby outputting a corrected data stream;an address filterer that is configured to receive the corrected data stream from said forward error corrector and to perform address filtering upon frames within the corrected data stream, thereby outputting frames selected in accordance with the address filtering; andan interface that is configured to receive the selected frames from said address filterer and to output the selected frames to the computer.
