DVB-S2
DVB-S2 is a newer specification of the DVB-S standard. Designers claim that DVB-S2 performance gains over DVB-S is circa 30%. Unlike DVB-S, it does not rely on MPEG2 encoding alone, but allows more advanced like H.264 (a.k.a. MPEG4 Part 10 or AVC) or DVB-S (intented for final consumers ) with QPSK, 8PSK (used in non-linear transponders near to saturation); 16APSK and FEC system based on concatenation of the Bose-Chaudhuri-Hocquenghem with a low density parity check. Performance should be 0.7 dB close to the Shannon limit.
