DVB-T2 is the next development of the Digital Video Broadcasting - Terrestrial standards. It builds on the technology and on the success of DVB-T to provide additional facilities and features in line with the developing DTT or Digital Terrestrial television market.

Although some may see DVB-T2 as a competitor to the existing DVB-T standard, this is not the case,. It is planned that the two standards will co-exist for many years, with DVB-T2 allowing additional features and services.

The new DVB-T2 specification provides the facility to select a variety of different options to match the requirements of the network operator.

For error correction technology, that used for DVB-S2 has been incorporated. This comprises LDPC (Low Density Parity Check) coding combined with BCH (Bose-Chaudhuri-Hocquengham) coding. The combination of these two techniques has been proved to provide excellent performance in the presence of high noise levels and interference.

As before, several options are available in areas such as the number of carriers, guard interval sizes and pilot signals, so that the overheads can be minimised for any given transmission channel.
