Digital TV. Television standards DVB-T2, DVB-S2 and DVB-C. What you need to know about the DVB-T2 digital set-top box
Today I decided to tell the guys what DVB-T2 is, one of my readers asked a question in. Many people do not understand what it is and do not see the advantages of using this digital broadcast format, but in vain! After all, using this format, you can watch for free digital television Russia. In our city there are 20 channels + 3 radios. According to rumors, the number of channels will only increase in the near future. In general, the format is needed, read on and I’ll tell you everything...
As usual, let's start with the definition.
DVB- T2 ( Digital Video Broadcasting Second Generation Terrestrial) – This is a terrestrial format of digital terrestrial television. PrefixT2 stands for the second generation of this format, designed to increase throughput signal 30 - 50% at the same equipment power.
Now in simple words. Guys, this is really a new broadcasting format. Previously, television worked on analogue networks, that is, there was a television tower and it transmitted analog signal to the consumer (TV). And the further you were from the tower, the worse the channel reception was, there was interference, etc.
Everything is different now. There is also a tower, only it transmits a digital signal. Something like cell tower, the consumer either has a signal or does not (just like on cell phone)! Moreover, if there is a signal on the TV, then the image is very clear and without interference. Even over long distances. If there is no signal, then the TV simply will not show, here you need to take a more powerful antenna, or use a television signal amplifier.
It should be noted that now almost all new TVs support the DVB-T2 format. Just connect the antenna, turn on the TV, select the DVB-T2 format (or digital format, maybe more digital reception signal) and that’s it, the TV itself will find digital channels. Everything is easy and simple. But old TVs are not designed to receive such channels, so they cannot receive DVB-T2, but there is a way out.
How to catch digital television on old TVs
ON old TVs or LED TVs that do not support the DVB-T2 format, you need to install a special digital set-top box. It picks up the digital format and then transmits it to the TV. It is connected either to HDMI connectors or to analog connectors (the well-known “tulips”). The cost of such set-top boxes now ranges from 1000 to 2500 rubles. The set-top box has a separate remote control, which is what you will use to switch digital channels.
Thus, it is even possible old TV turn into a receiver of the new digital signal(DVB-T2).
Guys, the most important thing is that this television is free, that is, you don’t need to spend money on cable or satellite TV. Also the image quality on high level, and the reception is much better!

In general, this is a real leap forward, you won’t regret connecting.
