Experience on operating a DBS system (BS-2) in Japan

In Japan, the direct broadcasting satellites BS-2a and BS-2b were launched in 1984 and 1986, respectively by NASDA (National Space Development Agency of Japan). Using the BS-2s, NHK (Japan Broadcasting Corporation) is gaining experience with direct broadcasting satellite service including high-definition TV coverage of the Seoul Olympics in 1988. The second generation satellite, BS-3a, is planned for launch in the summer of 1990. The authors discuss their four years of experience with operating satellite broadcasting carried out by NHK in collaboration with TSCJ (Telecommunication Satellite Corporation of Japan) and NASDA. Future plans are also outlined.<
