In a article previous we found that soon we should change the TV and the decoder. In this we will deepen how to know if you can still use your TV because the switch off is approaching.
Switch has now become a common term which means the definitive transition from an old transmission system to a new one
The switch off approaches
For ten months now, DTT channels have abandoned the MPEG-2 encoding standard, to switch to MPEG-4. The change took place in January of this year and, thanks to luck, it was quite easy to see if your TV was able to support the new standards. In fact, it was enough to tune the TV and access any HD channel, such as Rai Uno HD and Canale 5 HD.
If the format was supported in both video and audio versions, then we wouldn’t have had any problems. Things will not be so simple for the switch off scheduled for June 21, 2022. On that date, two new transmission technologies will be adopted, the HEVC and DVB-T2 standards.
L’HEVC (High Efficiency Video Coding) is a video compression standard and offers viewers a higher level of fidelity.
DVB-T2 (Digital Video Broadcasting – Terrestrial Second Generation) will instead act against noise and interference.
How to know if you can still use your TV because the switch off is approaching
Checking if your TV supports DVB-T2 and HEVC is quite complex. If you have lost your TV manual you may have problems. In fact, it is only by looking at the manual and the list of technical characteristics of the TV that we can know if our device supports the two new technologies or not.
There is no need to worry too much though! In fact, since 2017, there is the obligation to sell only TVs capable of supporting HEVC and DVB-T2. You may therefore only have problems if you bought a new TV before this date.
