Digital terrestrial corresponds to a series of technologies that belong to the television context, bringing the use of the appliance to a new dimension, new channels, better perceived quality and greater multimedia possibilities, on the other hand, since the first application of digital terrestrial, a form of constitutive update of televisions and decoders.
Digital terrestrial: here is the list of televisions that do not support it
The “first generation” of digital terrestrial, called DVB-T, began to be widespread in the first half of the 21st century and the whole process was completed within a few years.
At first the Italian state and then individual citizens had to progressively update the entire technological apparatus starting from the stations up to the repeaters and antennas. In detail, this has led to the “retirement” of all forms of devices that are not compatible with the new standard.
It ended in 2012 switch off which led to the switching off of the old analog channels to keep only the digital ones.
Something similar has happened, indeed is still happening, with the “passage” towards the second generation of digital terrestrial, this time necessary to “Free up” the frequencies useful for 5G. This time the changeover was less traumatic but still involved updating the devices with that of DVB-T2.
In 2023, everyone will gradually have to acquire a new TV equipped with the new standard, or a decoder compatible with the second generation Digital Terrestrial. Every TV sold from 2018 onwards is already “okay” from this point of view and will inevitably need to update the channels.
In all other cases it is sufficient to carry out a simple test to understand if our TV is already suitable for the new standard.
Just select a channel between number 100 and channel 200. If a white box appears on a blue background with the words “Test HEVC Main10” inside, there is no need for any new TV/decoder.
Otherwise (black screen) it will be necessary to fix it.
