We propose a digital transmission system for the satellite broadcasting using 12 GHz broadcasting satellite service (BSS) band. It is necessary for the system to provide the high quality and new digital services which have never emerged in the analog systems. In addition, it should take into account the improvement of the service grade to the current satellite broadcasting system since the current system has already more than ten million receivers. The new system introduces trellis coded 8PSK as a main modulation scheme to improve the spectrum efficiency for transmitting multi-channel HDTV, TMCC (Transmission Multiplex Configuration Control) signal as a flexible control to the modulation scheme, and a hierarchical transmission to secure the high service availability. Some necessary gate arrays for the demodulator suitable for the system have been developed.
