Abstract :
Broadcasting satellite (BS) digital broadcasting of HDTV in Japan is laid down by the ISDB-S international standard. Since it has a unique transmission technique that can use a number of modulation schemes simultaneously in one RF carrier, the most suitable modulation scheme for the broadcast content can be selected even within one RF carrier. In addition, a hierarchical modulation technique that can mitigate rain attenuation can be introduced as an application of this transmission system. This paper shows how the transmission system establishes such a versatile function.
