THROUGH OPTICAL FIBER

Described a new optic-fiber audio/video signal transmission system for distributing the DBS programs to the displays/receivers in a local area where there is no enough space to install antennas for each receiver. A customer who has a DBS receiver but no space for setting an antenna can receive the DBS programs through the optical fiber system. A customer who has no DBS receiver can also receive the DBS programs by a video display through the optical fiber system. The DG/DP of the transmission system for a video signal was under 4 % and 3 degrees. The distortion factor for an audio signal was under 0.08 % in mode A and 0.02 % in mode B, respectively. The SNR of a video signal was above 40 dB (unweight) and SNR for an audio signal was above 60 dB in mode A and 70 dB in mode B.
