This paper proposes a satellite TV broadcast service system for the Asian and Oceanian regions, not as an alternative overseas satellite broadcast system to existing terrestrial overseas broadcasting systems, but as a system in which each country would have its own broadcast programs. First, the meaning of satellite broadcasting for developing countries and study examples are described. Second, the present broadcasting situation in the Asian and Oceanian regions is surveyed and analyzed, in conjunction with the size of population and national incomes in various countries. Third, the necessity for a satellite broadcast system to countries either without a TV broadcasting system or only limited TV broadcasting hours or having the insufficient penetration of TV sets is discussed. Fourth, the possibility of establishing a satellite broadcast system is studied. The broadcast countries are supposed to be 7 countries in the Asian region and 8 countries in the Oceanian region. The following system parameters are examined. Reception system: Community reception. Frequency band: 14/12.5 GHz band. Satellite geostationary location: 125 degrees east longitude. Finally, the parameters of a broadcast satellite, AOSAT, is presented.
