For the DTT it is time again for a transition, after the switch-off of the analog signal in 2012: by 2022, in fact, the transmissions will pass to an advanced standard, capable of occupying less bandwidth, simultaneously guaranteeing a very high quality of vision . But how to check if the television in your possession is already compatible with the future system?
As already mentioned in a previous update, by 2022 all television transmissions will switch to the DVB-T2 standard, capable of guaranteeing a high resolution view – up to 8K – with low bandwidth consumption. The passage, established by law, will also be necessary to free up the 700 MHz frequencies, which will be used in the future for i 5G connections over long distances.
For the future switch off a calendar and, as happened in the past, the transition will be progressive to groups of regions:
- From September to December 2021: Valle d'Aosta, Piedmont, Lombardy, provinces of Trento and Bolzano, Friuli Venezia Giulia and Emilia Romagna;
- From January to March 2022: Liguria, Tuscany, Umbria, Lazio, Campania and Sardinia;
- From April to June 2022: Sicily, Calabria, Puglia, Basilicata, Abruzzo, Molise and Marche.
However, this is not all, since the transition to the DVB-T2 system will take place in two distinct phases. In fact, as early as 2020, the channels currently broadcast will pass by MPEG-2 encoding a MPEG-4 encoding – already in use for high definition – while by 2022 all the devices must be compatible with the HEVC standard, which significantly reduces the bandwidth occupied while simultaneously increasing the quality of vision.
Check your TV
As it happened for the previous one switch-off, the transition to the new DVB-T2 standard will lead many to almost forced purchase of new televisions or compatible devices, such as set-top-box is decoder. A necessary step to be able to take advantage of new transmissions, so much so that incentives and bonuses are provided for the less well-off families, so that they can carry out the transition without excessive bumps on their budget.
Fortunately, especially among those who bought a new TV recently, it is likely to be already compatible with the new standard:
- For the simple transition from MPEG-2 to MPEG-4, all the devices that are already able to reproduce will be compatible HD channels, which are based precisely on the MPEG-4 encoding;
- All TVs sold starting from 1st January 2017 they must be, by law, compatible with the DVB-T2 standard with HEVC coding.
To check your device, simply check the presence of the DVB-T2 sticker, usually pasted on the front or back of the device or, alternatively, on the box and in the instruction manual.
