The Czech Republic is currently preparing itself to switch terrestrial digital television broadcasting from the present DVB-T system to the more frequency-effective DVB-T2 system. The new system will allow viewers to receive high definition channels, further broaden the range of channels on offer and at the same time free up part of the radio frequencies for further development of mobile electronic communication networks used for high-speed Internet access.
The method of terrestrial digital television broadcasting currently used, DVB-T, should come to an end, following on from prior concurrent broadcasting using the DVB-T and DVB-T systems, roughly in 2020. Concurrent broadcasting over a larger geographic area is expected during 2017 at the latest.
In this regard, the Czech Telecommunication Office warns the general public, when buying a new television set, to pay heightened attention to the technical parameters of the new set. The use of a modern system of encryption termed H.265 or HEVC is expected for DVB-T2 terrestrial digital television broadcasting in the Czech Republic. However, this system of encryption is generally not found in the television sets available on the market at this time. The television sets currently sold on the market for DVB-T2 reception are usually only equipped with the MPEG-4 codec. However, such sets will be unable to process the prepared DVB-T2 broadcasting with HEVC encryption.
When buying a set for reception via cable television, CTU recommends asking for information from your cable television network operator.
