1. This system adapts DVB-S debugging mode, and transmits 4 frequency points in omni-direction and open circuit. Each frequency point can multiplex 12-15 sets of digital TV programs. It can transmitter a maximum of 60 sets of TV programs within 200M broadband.
2. Adapting entire encoded mode to process the program source, it is convenient for inserting advertisement and rolling caption, and can keep the rate of each program within 3-3.5 M.
3. QPSK modulating mode is suggested to adapt in practical project: QPSK modulating technology has strong anti-jamming ability. Compared with 16/64QAM, QPSK has a better BER(Bit Error Rate) Performance.
