DVB-T2 is the successor of DVB-T. It was published in 2009 and integrates a subset of the LDPC codes as defined in DVB-S2. Two LDPC codes (block length 16200, code rate 3/5 and block length 64800, code rate 2/3) were, however, replaced. While DVB-S2 uses LDPC and BCH coding only for payload data (so-called baseband frames, BBFrames), DVB-T2 uses two LDPC codes (16200 bits, rate 1/5 and rate 4/9) for the signalling of the current configuration of the DVB-T2 system.
