Features of CETV
Digital terrestrial television (TsETV), makes it possible to receive Federal TV channels and radio stations included in the first and second multiplex in the MPEG-4 standard. Below you can find a list of these channels.
The peculiarity of this type of TV broadcasting is that you can watch the listed TV channels in high quality. As you know, the past generation of broadcasting - analog terrestrial TV, is already outdated, since the broadcast picture has a low resolution, and on modern widescreen TVs the image has a very low quality and is blurry. The new broadcasting format opens up new facets, giving subscribers a high-quality clear picture and high-quality stereo sound.
CETV broadcasting is carried out in principle, like ordinary broadcasting of decimeter channels, only one channel includes 10 digital ones. There are only 2 such channels, they represent the first and second multiplex. To process the signal, you need a special digital terrestrial receiver - a set-top box.
Equipment
Let's take a closer look at the set of equipment that is required to receive high-definition digital terrestrial TV channels.Necessary equipment:
- Antenna;
- Receiver (tuner);
- Amplifier;
- Coaxial cable;
- Cable for connecting the receiver to the TV.
To receive the CETV signal, an ordinary decimeter antenna is needed, which receives channels in the frequencies of 470-860 MHz. Antennas can be of two types: indoor (indoor) or outdoor. The type of antenna must be selected relative to the distance from the TV tower (repeater).
A home antenna is suitable only when there is a TV tower in your city, no more than 15 km from your home. In this case, you can get by with a room antenna. If your distance to the TV tower is more than 15 km, then you need to use an external antenna.
In the shop household appliances or radio electronics, there will be decimeter antennas for DVB-T2. Purchase special antennas that are designed to receive a decimeter signal, they are designed according to all the rules of radio physics and will provide high-quality signal reception.
Talk to your neighbors, for sure some of them watch DTV, find out what kind of antenna they use and what is the level and quality of the signal.
When in doubt, buy an external antenna.
Receiver (tuner)
The first thing to do is to choose a receiver. The receiver is a special set-top box for the TV, as mentioned earlier, which processes the signal and sends it to, channel tuning and switching is also done through the receiver. Today on the market there is a fairly wide selection of receivers for receiving DVB-T2 channels.
As for the choice, they are all almost identical and simple, choose a device based on the availability of additional functions: functionality and menu design, as well as the availability of connectors for connecting to a TV.
In some modern TVs, from the middle and premium segment, there are models with a built-in DVB-T2 tuner, thanks to which you will not need to buy a receiver, but simply connect the cable from the antenna to the appropriate jack and tune the channels.
If you have, then some models support the installation of CAM modules, including the DVB-T2 module. Thus, you just need to install the module in the receiver, connect the cable from the antenna to the second input jack, and you can watch digital terrestrial television channels along with satellite ones.
Amplifier
Most decimeter antennas (both indoor and outdoor) include a built-in amplifier, the signal from which is amplified by the receiver, which is quite enough for reliable reception, if the antenna type is chosen correctly.
Consider the cases when you need a separate signal amplifier. Using the DVB-T2 receiver, you can check the signal level, for this you need to enter the settings and the corresponding scale will be displayed there. Connect the antenna to the receiver - if the signal level is around 75% and the picture quality suits you, then the amplifier is not needed. When the signal level is lower and the picture is noisy, it is recommended to install an amplifier.
Coaxial cable
This is a regular TV cable that transmits the signal from the antenna to the receiver. We recommend purchasing a cable with a copper loop and screen, as it is of the highest quality, which will provide good gear signal and long term operation of the cable. Pay attention to the cable sheath, the stronger it is, the better, since the cable will be less exposed to external influences: interference and destruction.
Cable for connecting the receiver to the TV
If your selected receiver includes hDMI connector, which is also available on the TV, it is better to use it for connection, since given type connectivity provides best quality Images. For this you will need HDMI cable, which can be bought at any hardware or computer store.
If there are no HDMI connectors, which is somewhat bad, then use SCART, RCA and others.
Installation and setup
First, we install the antenna. An indoor antenna is usually installed on a window. External antenna you can try to install it on the balcony or fix it near the window on a bracket if you live in the side where the TV tower is located. Route the cable from the antenna to the receiver. In the case when the signal is weak enough, or the TV tower is in the other side, then the antenna must be installed on the roof of the house. Direct the antenna towards the TV tower, for this it is enough to look at the direction of the adjacent antennas.Unpack the receiver, connect the cable from the antenna, then connect the cable from the TV. Next, turn on the receiver to the power, turn it on and make initial settings: language, time and time zone, etc.
If the model supports automatic channel scanning, then you can use it. If automatic search no, then in manual mode you need to select desired channels two multiplexes. In the regions, these channels may differ, most often they are channels 35 and 45.
Find the channel of the first multiplex and scan it, and then select the channel of the second multiplex and scan it too. The fact is that each of these channels contains its own package of 10 channels. By the way, it is in this settings menu that the signal level scale will be displayed. If the signal level is low, you can rotate the antenna, choosing its best direction, based on the scale values.
That's it, now you can enjoy watching digital terrestrial television.
Let's consider step by step the procedure for setting up digital television on modern TV models with built-in DVB-C, DVB-T2 (T1) tuners. We do not consider connecting and setting up digital television using receivers (NTV +, Tricolor) in this article.
1) First of all, make sure your TV is capable of watching digital channels. To do this, you need to open specifications your model and find the parameters DVB-C, DVB-T1 (DVB-T2): (find your model by the manufacturer's name or by writing it in the search bar in the upper right corner of the site).
If your TV has built-in tuners digital signal (DVB-C, DVB-T1 (DVB-T2)), then, subject to the availability of TV companies broadcasting in digital format, you will be able to set up digital TV.
2) The second step is to decide the type of antenna that will receive the signal. The most common option at the present time is cable TV, connected to the TV by coaxial cable, with payment for services once a month. Another option is to take an antenna of the "spear" type (previously supplied with TVs), or another type of antenna that receives an analog broadcast signal. NO special antennas for digital TV reception (we are not talking about satellite dishes Tricolor, etc.), so if they try to sell you something futuristic under the heading “for reception digital TV broadcasting"- don't waste your money. The frequency range of digital television broadcasting is quietly covered by an ordinary antenna installed on any multi-storey building from the times of the USSR. A detailed description of why you should not buy special antennas: http://rem-tv.net/publ/8-1-0-102
3) Suppose the antenna is selected. There are now two ways to set up digital TV: fast and long.
a) The quick method is to find the website of the TV company that broadcasts in your area (Yandex will help you here). As a rule, if a TV company broadcasts TV channels in digital, then the website contains information about this and settings that need to be entered into your TV for quick and accurate searches.First, you should turn on the "Cable TV" reception mode and set the parameters, for example, like this: 3 packet (frequency 634000 MHz, speed 6750 Ksymbol / s and modulation 256 QAM. If the TV company is broadcasting digital channels, occupied the frequency, but the broadcasting is temporarily not conducted, then the TV will display black screens instead of the image (this is a question for the TV company).
b) A long method, but sometimes giving unexpectedly pleasant results, is to search for digital channels in everything accessible TV range (shown in the photo below).
With the advent of the digital terrestrial television era, many cable and satellite subscribers are increasingly thinking about connecting free broadcasting... Indeed, according to the FTP, on the development of the digital broadcasting network, in open access will appear more than twenty television channels in excellent quality absolutely free. Which includes mandatory federal television channels.
The question arises - how to connect digital terrestrial television at home?
This is not difficult. To receive digital terrestrial television, you will need any subscriber equipment of the standard DVB-T2 / MPEG-4 with mode support Multiple PLP and decimeter antenna ( UHF) range. The antenna can be either collective (installed on the house, also called common in the house) or individual, installed directly in your house or apartment. Depending on the distance to the transmitting center, the correct antenna must be selected. They are divided into active (with an amplifier) \u200b\u200band passive. When buying an antenna, you can first check the power of the transmitting equipment installed in your area and the distance to the transmitting center. Based on the data received, select an antenna.
Approximate coverage radius of transmitting stations:
10 watts - about 3 km;
50 watts - about 5 km;
100 watts - about 15 km;
500 watts - about 25 km;
1 kW - about 30-35 km;
2 kW - about 35-40 km;
5 kW - about 40-50 km.
Let's go directly to the equipment for receiving. Three main groups can be distinguished: TVs with a built-in DVB-T2 tuner, set-top boxes of the same standard and digital computer DVB-T2 tuners. Their setup is similar, if not the same.
Check if your TV can receive DVB-T2 signal
Video: how to set up digital terrestrial television DVB-T2
It is best to connect a digital terrestrial set-top box according to the manufacturer's instructions, it is almost impossible to make a mistake there. Also, you can watch the official video from RTRS:
Several recommendations, also from RTRS:
connect the plug antenna cable and, if necessary, digital set-top box to the TV;
connect autosearch of channels - the TV will tune to the corresponding digital terrestrial channel, when tuning to a channel in manual mode, you must specify the channel frequency (for example, 35 TV channel, 685 MHz);
in most digital TVs (and in consoles) there is a built-in indicator of the signal level and quality, which will optimally tune your antenna to receive digital broadcast signal (see the operating instructions for the TV).
On TVs with a built-in DVB-T2 tuner, all manipulations are carried out through the TV menu. Difficulties should not arise there either.
We recommend updating the software of your subscriber equipment to the most current one. This can be done in specialized services, or yourself (if you are confident in your abilities). Software can usually be downloaded from the manufacturer's official websites.

TV), it's time to move on to the most important part - setting up digital television... How to set up digital TV with your own hands? Read on for more details.
I will show using the example of a receiver Mystery MMP-71DT2and like me, his software is exactly the same as Rolson's. If you have a different set-top box, the principle will be the same, but you may have to look at the instructions.
How to connect everything
First, we connect antenna to the receiver, and the receiver to the TV... Preferably via an HDMI cable, so the image quality will be as clear as possible. If there is none, then through the usual "tulips", they come complete with a prefix, as a rule. We look at the connectors in the instructions, you get something like that. If the antenna is with an amplifier, first turn it off, then you can always turn it on.
We launch all this economy, set-top box, antenna, TV. We select the required video input. If everything is done correctly, then you will see a start menu of this type:
How to set up digital TV via autosearch
By default, the set-top box is not configured for anything, and you yourself will need to catch the channels that are transmitted in your region. The easiest way is to start autosearch.
After launching autosearch, the set-top box will think for a long time, and must find something in the end. Important: since everyone is transmitted on the same frequency, then you will catch channels not one by one, but immediately in batches of ten. So be patient. If in analog TV channels are caught one by one, then it may take several minutes, and the set-top box will search. But then all 10-20 channels will immediately pop up.
After the search is over, the STB will offer you to add the found channels. If you find all 20 pieces - congratulations, the process is complete!
List of tuned channels, function "TV Guide"
How to check the signal quality when setting up digital TV
Check that the signal is strong enough and everything is set up well.
It's very easy to do. You must have an INFO button on your STB, triple tap displays data on the quality and intensity of the signal. Look in the instructions, it may have a different name, but it will do the same:
The higher the signal, the better. Optimally - from 60% onwards
If both indicators are high, above 60%, everything is fine.
Check it out on both multiplexes, say on Channel One and TNT.
Since different multiplexes are transmitted, you can catch the first one well, and the second one bad, or vice versa. Your task is to turn the antenna so that both are well caught.
But in practice it happens a little differently. For example, you can catch takes. When the same channels will occupy several places at once. It seems not critical, but annoying. How to treat me.
What to do if you caught takes, or nothing was caught
The second option is when not everything was caught, or nothing was caught. Here will help us fine tuning and manual mode. We read about it. However, if you live in a city, and there are towers near you, then in 90% of cases autosearch is enough for you.
Summarizing
As you can see, setting up digital tv dvb t2 with your own hands is not a complicated business. And you certainly shouldn't call a master who will do the same for you for a thousand rubles)
