DVB-S2 is the second-generation specification for satellite broadcasting developed by the DVB Project in 2003 and needs to be seen in conjunction with the world-famous DVB-S specification which was finalized in 1993. It benefits from more recent developments in channel coding (LDPC codes) combined with a variety of modulation formats (QPSK, 8PSK, 16APSK and 32APSK). When used for interactive point-to-point applications like IP-based service navigation, it may implement adaptive coding and modulation (ACM), thus allowing the transmission parameters to be optimized for each individual user, dependent on path conditions. Backwards compatible modes are available, allowing existing DVB-S services and Set Top Boxes (STBs) to continue working during any transitional period.
