Abstract(in English) | The direct satellite broadcasting (DSB) through communication satellites (CS) is now monopolized by the company SkyPerfecTV and the transmission sites are located only in Tokyo area. This narrow transmission side of the system may have caused premature saturation of the market. The DSB system herein proposed enables direct transmission of independent signals from multiple sites in remote areas toward a satellite transponder which is shared by those stations in TDMA modes and the combined signal can be received by existing DSB receivers. In another words, it realizes a truly direct satellite broadcasting system for the transmission sides as well as the receive sides. The system enables the local broadcasting stations expand their coverage areas from prefecture to nationwide scales at minimal investment additional to the vast ongoing digitalization cost. The direct flow of information from any local areas to the whole national region will then create new business opportunities for local industries and contribute to the well balanced development of the nation. |
