The specification is designed primarily for fixed reception to roof-top antennas and has frequency spectrum channel characteristics that are compatible with with Geneva 2006 Agreement. DVB-T has been published as an ETSI standard, EN 300 744. It is built on top of MPEG standards for aiudio/video coding and multiplexing, which are used according to the MPEG guidelines technical specification ETSI TS 101 154. DVB-T transmits compressed digital audio, video and other data in an MPEG transport stream, using COFDM modulation. The transmission mechanism, which is based on data symbols, uses Multiple Carrier Frequencies. OFDM works by splitting the digital data stream into a large number of slower digital streams, each of which digitally modulate a set of closely spaced adjacent carrier frequencies. In the case of DVB-T, there are two choices for the number of carriers known as 2K-mode or 8K-mode. Within each frequency, DVB-T offers three different modulation schemes (QPSK, 16QAM and 64QAM) which choice is made depending on a robustness versus data rate compromise. One of the main advantages of OFDM is that it allows the receiver to cope with strong multipath situations. DVB-T also allows single frequency networks (SFN) operation within a given geographical area, where two or more transmitters carrying the same data operate on the same frequency.

A draft PSI/SI (program and system information) specification document was also agreed with the DVB-TM-GBS group. Prototype receivers were shown in September IBC 2008 and more recent version at the IBC 2009 in Amsterdam. A number of other manufacturers demonstrated DVB-T2 at IBC 2009 including Albis Technologies, Arqiva, DekTec, Enensys Technologies, Harris, Pace, Rohde & Schwarz, Tandberg, Thomson Broadcast and TeamCast. As of 2012, Appear TV also produce DVB-T2 receivers, DVB-T2 modulators and DVB-T2 gateways. Other manufacturers planning DVB-T2 equipment launches include Alitronika, CellMetric, Cisco, Digital TV Labs, Humax, NXP Semiconductors, Panasonic, ProTelevision Technologies, Screen Service, SIDSA, Sony, ST Microelectronics and T-VIPS. This system transmits compressed digital audio, video, and other data in "physical layer pipes" (PLPs), using OFDM modulation with concatenated channel coding and interleaving. The higher offered bit rate, with respect to its predecessor DVB-T, makes it a system suited for carrying HDTV signals on the terrestrial TV channel (though many broadcasters still use plain DVB-T for this purpose). In June 2006, a formal study group named TM-T2 (Technical Module on Next Generation DVB-T) was established by the DVB Group to develop an advanced modulation scheme that could be adopted by a second generation digital terrestrial television standard, to be named DVB-T2.
