- Currently we are in the phase of Transition from DVB-T1 to DVB-T2 Standard. DVB-T2 enables a very efficient coding (H. 265) of the video signal, many channels in relatively little bandwidth to accommodate.
- About the middle of 2019, all broadcasts will be switched off in the DVB-T1 Format.
- A new antenna do not need to install them in most cases. One of the core ideas of the new Standards was that the old antennas have to be for the most part, compatible.
- Your age DVB-T1 Receiver is not compatible to DVB-T2, which is why you have a new Set-Top Box or a television with integrated Decoder need. In almost all current TV models, this is already the case. When buying, make sure the DVB-T2 Logo.

- Here it is so that the HD channels are usually transmitted via DVB-S2 and the SD channels via DVB-S. DVB-S2 has been in terms of HD content developed and offers a better error protection as well as optimized video coding (H. 264).
- Exceptions confirm the rule. For example, WDR HD Aachen or WDR HD Wuppertal are still on the old DVB-S Standard.
- For you as a customer this means that you should have a Receiver that supports both Standards.
- Most modern televisions have a Tuner for both Standards, because it is not certain how long it parallel broadcasts via DVB-S(1) will give. Otherwise you need an external Receiver.
