In 2005, DVB-S2 spec. was finalized. But with a large number of DVB-S receivers already installed, backwards compatibility may be required for a period of time, where old receivers continue to receive the same capacity as before, while the new DVB-S2 receivers could receive additional capacity broadcasts. To facilitate the reception of DVB-S serviced by DVB-S2 receivers, implementation of DVB-S in DVB-S2 chips is highly recommended. For the backward compatibility the system adapt the hierarchical modulation scheme. And the system has to meet system margin, so in this paper analyzes the effect according to the deviation angle and shows the BER performance. And finally this paper shows the result of the system implement using FPGA chip.
