We have spoken on other occasions of the importance of DVB-T2 when buying a television. It is the call to replace the DVB-T that we currently use and that for the uninitiated is not more than the standard that gives us access to DTT that we have in Spain and in other markets.
But the arrival of the improvement in the image with UHD resolution and improvements like the HDR have made it useless. Hence, the DVB-T2 is the future and when buying a TV it is interesting to verify that among its specifications offers this possibility. A standard that offers more quality in the image thanks to a better compression of the data used.
However for the DVB-T2 to be a reality we will still have to wait . We must wait until the frequency division is changed and the 700 MHz band is released for the use of 5G in telephony. In fact we will go until almost 2022 to see the DVB-T2 in Spain.
Something that contrasts with other countries in our environment ; markets like Finland, Italy (of which we once spoke), Romania or the Czech Republic that have already begun to test the DVB-T2 in a period of adaptation. In the case of the Czech Republic, the last one to sign up for this club, the adaptation period will go from January to March 2018, to reach 95% of the population in June 2018, and the entire process must be completed in June 2020.
It draws attention so that in countries like Spain the DVB-T is still used and it is not yet clear when it will bet on the DVB-T2. In total, 19 countries that use the DVB-T that are expected to be reduced in the year 2022, when 16 countries will already have the DVB-T2 operational.
A DVB-T2 in which the bet will be for the H.265 codec or HECV (High Efficiency Video Coding) of which we have already spoken and that among other improvements will allow to reduce in half the bandwidth necessary for the transmission of video and all without the dreaded loss of quality that we do find in other market alternatives like the current H.264.
A year in which it is expected that more than 72% of European households have DVB-T2 compared to the 30% that currently enjoy it thanks to the arrival of powerful markets that make use of this technology (without detracting from the current ones ).
A year in which in theory, in Spain we should have this system for which the televisions will have to adapt their emissions and users will have to adapt antennas and in many cases buy new televisions (or in their absence external tuners DVB-T2) if they do not have a model prepared for the DVB-T2 (they are still sold, few yes, models that do not offer this compatibility).
