DVB-T2 is a digital terrestrial transmission system developed by the DVB Project. It is the most advanced such
system in the world and introduces the latest modulation and coding techniques to enable highly efficient use
of valuable terrestrial spectrum for the delivery of audio, video and data services.
As with its predecessor, DVB-T2 uses OFDM (orthogonal frequency division multiplex) modulation, with a large
number of sub-carriers delivering a robust signal. DVB-T2 uses the same coding that was selected for DVB-S2.
LDPC (Low Density Parity Check) coding combined with BCH (Bose-Chaudhuri-Hocquengham) coding offers
excellent performance in the presence of high noise levels and interference.
Several options are available in areas such as the number of carriers, guard interval sizes and pilot signals, so
that the overheads can be minimized for any target transmission channel. A new technique, called Rotated
Constellations, provides significant additional robustness in difficult channels.
