DVB-T2 is the next generation in digital terrestrial HD transmission. Building on the foundations of the successful DVB-T system, the current standard for transmitting DTT broadcasts (known as Freeview in the UK), DVB T2 introduces the latest modulation and coding techniques to optimise the efficiency with which the terrestrial spectrum is used to deliver video, audio and data services.
DVB T2 has been introduced to deliver Freeview HD in the UK. A new video compression standard: MPEG-4 AVC has also been introduced to create sharper and more detailed high definition pictures. These new techniques give DVB-T2 software a huge 50% increase in efficiency over any other DTT system in the world.
