Digital satellite direct broadcast system

The satellite radio broadcasting system (10), can be used for program playing position to assemble the main rate wing part, capacity assembly brackets (100). A frame (100) is divided into each marks, the back dmuxes are multiple main of channels (110). The host of channels (110) is dmuxes to corresponding number and frequency (21) is used to transmit the satellite (25) and method. The machine dmux (144) uplink signal separated for time-division multiplexing mark stream (154). Phase-shift keying demodulator (146) symbols for demodulation digital baseband data. The satellite payload uses two relapses to the contact with the buffer (156) and a route switch (172) into a symbol and time-division multiplex data stream. The receiver (29) is service control first (23,24) is provided by a radio station for processing data stream and managing system for time-division multiplexing of the frame comprises program and control channel of satellite (25) is provided is used to manage the satellite (25) and a control radio station (23,24).
