DVB-T2 HD is the new generation of antenna-based television. The abbreviation stands for Digital Video Broadcasting – Terrestrial, 2nd generation. The new distribution channel combines the DVB-T2 broadcasting standard with the new and improved HEVC video codex, allowing for the distribution of more programmes with improved video quality (up to full-HD) at a lower cost.
Why DVB-T2 HD?
The rapid developments in audio-visual end device technology, the reallocation of the frequency spectrum and the increasing mobility of consumers require an improved method of programme distribution. The picture quality should be higher, the data rates smaller and the transmission path more stable. As a result of the changeover to DVB-T2, it will be possible for these requirements to be met since not only are the distribution path and frequency changed when switching from DVB-T to DVB-T2 but, at the same time, the video codex is changed to HEVC as well.
The following advantages result for viewers:
Picture quality: DVB-T2 HD enables the possibility of HD television via antenna. In most cases even in full-HD (1080/p50).
Programme diversity: On the same basis, DVB-T2 HD offers the possibility of expanded programming: around 40 channels will be possible in metropolitan areas at the official launch in Germany.
Mobility: The stable distribution path allows for large-scale portable use and even mobile use in cars.
When will DVB-T2 HD be launched?
The first introduction stage began at the end of May with a test operation in Germany. On 29 March 2017 regular operations will be launched with 6 HD multiplexes in each of 18 metropolitan areas and a total of 40 TV channels. From that point forward, all channels will gradually switch over to DVB-T2 HD until the beginning of 2019.
What do viewers have to be aware of?
DVB-T2 HD devices have been available on the European market for some time now. In Germany, the HEVC video codex is new; therefore, consumers have to make sure that the devices carry the green DVB-T2 HD logo when making a purchase.

What does the IRT do for DVB-T2 HD?
By the time broadcasting switches over to DVB-T2 HD in 2017, the IRT will have already done a lot of work behind the scenes. The encoders and decoders from the various manufacturers have been tested with different broadcast formats, and comprehensive transmission tests, also with regard to mobile reception, were done in cooperation with BR in the test transmitter network. For mobile Android devices, a DVB-T2 HD app was developed in cooperation with WDR. And, of course, the negotiation results from the World Radio Conference WRC-15 were important for preserving the frequency spectrum for the further development of broadcasters. The IRT participated in the WRC and supports the broadcasters with frequency planning and regulation.
