International Transmission of HDTV Signals

To confirm the feasibility of the international and domestic program transmission via satellites, international transmission experiments from Japan to Australia and from Korea to Japan using the MUSE signal were successfully carried out in 1988. The first transmission was conducted on three-hop basis using CS-2,- INTELSAT, and AUSSAT. The second transmission was the live-broadcasting of the Olympic Games in combination with INTELSAT and BS-2. In both transmissions, the CN ratio of about 17.5 dB, which corresponds to the limit of perception of the noise impairment was obtained. Excellent waveform transmission characteristics were also obtained by employing IF and baseband equalizers. Through these experiments, it was concluded that international and domestic transmission of HDTV can be done by existing satellites and earth stations without modifications as long as modulators and earth stations are connected by an IF signal.
