How to connect DVB-T2 digital television?

You need an antenna (indoor or outdoor), set-top box or TV with a built-in tuner. In apartment buildings, there is most often no common antenna. The signal in the home network is provided by cable operators; DVB-T2 is not included.

Why is there no signal on the TV?

Provided that it was there before, it is necessary to check the connecting cords for damage, turn the equipment off and on, and perform an automatic channel scan.

What antenna is needed for digital television?

Broadcasting is carried out in the UHF range, so any antenna will do. When purchasing a new antenna, pay attention to the DVB-T2 mark and the gain.

What is the difference between an active and passive antenna?

On active antenna A standard amplifier is installed, power is supplied from the power supply, which is located next to the TV, which is convenient for one TV. You can connect a separate amplifier to a passive antenna, and after it divide the signal into several points.

How to connect digital terrestrial television through an indoor antenna?

The use of an indoor antenna is possible only in the area of ​​reliable coverage of the repeater, most often within the direct line of sight of the tower.

Is it possible to connect two TVs to one set-top box?

Technically, this is possible. Either directly or through an external RF modulator. But such a scheme is extremely inconvenient; both TVs will simultaneously show the same program and channels must be switched directly on the set-top box. It is more convenient to install an additional receiver.

Why does the digital terrestrial television signal disappear?

Insufficient signal level leads to periodic broadcast interruptions. In such cases, a more powerful antenna and reinstallation at a higher point are necessary.

What cable should I use for TV wiring?

Coaxial cable with a resistance of 75 Ohms, it is advisable not to buy a cable thinner than 6 mm. The manufacturer can be any. Remember - “Good things don’t come cheap.” If the cable is laid for life, it is better not to save.

Why are the channels encrypted?

Some channels' broadcasts may be encrypted for broadcast testing purposes. At the beginning of 2018, there are no paid DVB-T2 channels.

Our company’s specialists connect and configure free tv channels analogue and digital terrestrial television transmitted by the Russian Television and Radio Broadcasting Network from the Ostankino TV tower. Connection and setup are carried out on televisions and television receivers - terrestrial TV tuners (set-top boxes). We provide service to all districts of Moscow and the nearest districts of the Moscow region. Organized for the convenience of users.

Terrestrial television. How to watch TV channels for free.

To the territory of Moscow and the Moscow region from the Ostankino television tower of the Russian Broadcasting Network rtrs.rf are transmitted free terrestrial television channels: 19 analog and three packages of digital TV channels (10 channels in each package), which allows you to receive without any subscription fee for individual indoor or outdoor programs of Russian television. You can even use a piece of wire one to two meters long as a receiving antenna. Broadcasting is carried out in the range of meter and decimeter waves; transmitted TV channels can be watched for free.

We bring to your attention a list of frequencies of free television channels on terrestrial television, designed to streamline your TV setup. Specifying the broadcast frequency of a specific TV channel speeds up setting up TVs that do not have an automatic TV channel sorting function. It also allows you to tune television channels to older models of televisions, in which, as a result of changes in circuit parameters, the automatic frequency adjustment system of the APCG local oscillator does not work properly.

The table shows the analog frequencies required to watch TV channels for free on TV.

Initially, digital broadcasting was carried out by the company rtrs.rf in the DVB-T system. In some regions it still works, but will soon be completely replaced by broadcasting on the new digital terrestrial television broadcasting system DVB-T2, which has been adopted as a standard. Televisions and set-top boxes released with a DVB-T tuner do not allow you to watch television programs they will not work in the new television broadcasting system.

How many channels does the digital set-top box 2019 show?

How many channels does a digital set-top box show? DVB-T2 terrestrial television?
Using an on-air digital set-top box, you can configure three multiplexes: RTRS-1, RTRS-2 and RTRS-3 with ten channels each, as well as 12 channels of the “fourth multiplex”, for a total of forty-two. So, the list of free digital terrestrial TV channels received in Moscow and the Moscow Region consists of three packages of ten channels each and a package of twelve channels.

The first multiplex of digital television in Russia RTRS-1

IN first multiplex includes a set of 10 free TV channels, broadcast on the frequency of the 30th TV channel 546 MHz using the DVB-T2 digital terrestrial television system.
Moscow terrestrial television can be downloaded on our website.

The second multiplex of Russian digital television RTRS-2

In second multiplex includes a set of television channels received on the 24th frequency channel 498 MHz in the DVB-T2 system. Unlike television programs included in first multiplex included in second multiplex TV channels are not required for free distribution by satellite and cable television operators.

The third multiplex of digital television of Russia RTRS-3

Third multiplex broadcast in 2019. Third multiplex digital terrestrial television is transmitted in test mode on the vacant frequency of television channel 34, on which broadcasting was previously carried out in an outdated system digital television DVB-T. Ten digital package positions are distributed among television program creators, who share broadcast time among themselves. Among them there are terrestrial TV channels high definition- IQ HD and HD Life.

TV channel Hunting and Fishing. TV channel Drive

When automatically scanning digital terrestrial television bands, in addition to those described above, at a frequency of 562 kHz, 12 programs are detected: 10 channels of the first multiplex, as well as TV channel Hunting and Fishing And TV channel Drive.
Sometimes these 12 television channels are called the fourth multiplex in Moscow. The quality of the transmitted signal from the channels of the fourth multiplex is much worse than on the first three: 8K instead of 32K, and the signal level is almost half as much. Therefore, channels are played back in worse quality and with image fading. The first ten channels after auto-tuning can be deleted.

And leave the next two channels, because today, digital channels frequencies 562 kHz - the only possibility free viewing the popular TV channel for hunters and fishermen "Hunting and Fishing", as well as the TV channel "Drive" for fans of cars and motor sports.
When choosing a receiving antenna for terrestrial digital television, you should focus on the acceptable quality of reception of these very weaker TV channels, Hunting and Fishing and Drive.

What to do if digital channels on your TV disappear

Why digital channels disappeared on a tuned television receiver? Nowadays, when terrestrial digital television is just beginning to explore the Russian expanses, the question of the disappearance of one, several channels or a whole dozen multiplexes is sometimes asked by all owners of digital terrestrial receivers.
The Russian TV and Radio Broadcasting Network RTRS, which is changing broadcast parameters, knows exactly why and where digital television channels are disappearing.
In order for the missing channels to reappear on your receivers, you should re-automatically or manually search for channels on an external terrestrial receiver, or on a TV with a built-in digital receiver of DVB-T2 terrestrial channels.

Answers to questions on free-to-air television

Double image from indoor antenna

Our TV doubles, as if it were in 3D mode, we can’t set it up.

Dual image appears when watching analogue terrestrial television, when the antenna receives direct and reflected signals from the television tower. The signal reflected from high-rise buildings arrives with a slight delay, which leads to a ghosting effect. It is necessary to use an antenna with a good radiation pattern, preferably an external one, and orient it in the best possible way towards the television center.

TV Erisson 43ULEA99T2SM does not find a single DVB-T channel

I can’t watch channels via DVB, I bought a separate antenna, I turn on the auto search, it doesn’t find a single channel, I’ve already changed the region from Russia to Germany, and manual search. What to do? 10.30.2018, Moscow, Chertanovo district.

To set up digital terrestrial channels on your TV, as on any other TV, you must, without changing the country of residence, set the option of digital terrestrial (terrestrial) channels DVB-T2 in the Menu, connect your own external antenna and enable auto-tuning.
Two points are significant: To watch free-to-air TV channels simultaneously on several TVs, you need to connect to a special splitter - a splitter, which divides the input television signal from the antenna into several outputs independent of each other. Any splitter, or as they also say “crab,” weakens the level of the TV signal. Therefore, you may need to install a special one that is powered from an electrical outlet. To obtain an image best quality, the antenna amplifier should be located in close proximity to the antenna.

This question is very relevant now, because analogue television broadcasting is promised to be switched off in Russia this year.
There is no need to be afraid of this; you can set up digital television on a DVB-T2 set-top box. How to configure - by turning on automatic search programs. And it is not necessary to change the receiving antenna; radio waves can be received using an already installed and oriented analog one. Unless you want to get rid of the heavy and bulky old antenna and instead accept and tune digital television to a small-sized UHF range.

Broadcasting digital terrestrial television of the DVB-T2 standard covers almost the entire territory of the Russian Federation. As we already know, you can check the availability of airwaves on the map. If broadcasting is carried out in a given region, then for reception you will only need subscriber equipment of the required standard, in our case - DVB-T2.

But the following may happen. You bought reception equipment (or already had it), but you can’t set up digital terrestrial channels. What could it be problem? The most common are:

The antenna is not intended for receiving digital terrestrial television (does not receive the UHF range);
Your hardware software is not up to date;
The equipment does not support the DVB-T2 standard.

Not all antennas are capable of receiving digital terrestrial television signals. Most often, people who connect their equipment to their home antenna encounter a lack of signal. There is no way to guess whether this antenna supports UHF reception. You need to call the organization servicing the house and find out. You can immediately buy an antenna and enjoy digital television reception. Let us remind you that there are no There are no special antennas for digital TV . If you are close to the transmitting equipment, then you can.

If your equipment is outdated software, then it may also not receive a digital terrestrial television signal. This problem can be solved either by reflashing the device yourself, or by taking the device to a service center.

If you decide to update the software of your device yourself, then download the firmware from the manufacturer’s official websites.

Well, of course, if your equipment does not support the DVB-T2 standard, it will not receive the signal.

Also, even with the correct equipment settings, the image may “scatter into squares.” Most often this is due to a low-power antenna or a large distance from the transmitting station. In this case, a more powerful UHF antenna will help you.

When setting up the equipment, point the antenna to the side and turn it to the maximum value of the “quality” scale on the set-top box/TV.

Everyone who lives in the age of high technology is sure that these technologies are designed to make life easier. This is true, although there are situations that can contribute to nervous tension rather than relaxation. For example, when some of your favorite TV channels disappear. Naturally, this is far from the best experience, especially when you want to watch TV, but it throws up similar, not very pleasant surprises.

If you also encounter a similar problem, then there is no need to rush to a television repairman, especially since this may take some time. If you wish, you can try to restore digital channels on the TV yourself. Of course, a 100% return of their broadcast cannot be guaranteed, but, as a rule, independent manipulations help.

Reasons for missing channels

As a rule, the TV shows two dozen standard digital channels. But sometimes even they disappear, if not completely, then partially. Considering that they are free, problems with broadcasting can be associated with many reasons, but the main ones can still be identified:

Problems with the program;

Problems with the signal receiving equipment.

Both the first and second situations can be solved, but they require completely different manipulations. If it's a hardware issue, then attempts regular user They don’t always help, and can even cause harm. If there is a problem with the TV channel itself, then this happens with one, maximum, two programs, but not with half of the broadcast channels at once.

Let's figure out what the number represents before doing any manipulations related to recovery processes. So, the advantages of digital television channels are improved signal reception, cooler sound, picture and other characteristics, compared to other free systems. But only 20 channels are free, which are periodically switched off and changed, so in a situation where some TV channels have disappeared, there is nothing surprising.

A paid channel symbol appeared on the screen. This is a sign that the subscription to services is ending. If you didn’t pay for the digital price on time, the answer to the question why the channels on digital set-top box, obvious. You need to top up your account and then they will start working again, of course, if this message does not pop up on free channels. In this case, it is better to contact your provider for clarification;

There may also be difficulties with the software, or more precisely, its compatibility. If this is a GS-HD receiver, then you need to go to the menu and press the “Restore channel list” button. If the new software is not suitable, then on the same receiver you need to: find the TV/RADIO and CHANNEL buttons on the remote control, and also press the same buttons on the receiver panel in parallel. But it is very important to do this at the same time. Then press the STANDBY button on the remote control;

The inscription “No signal”. This is already a standard sign of problems with the antenna. If the antenna does not work as it should, it is not surprising that dozens of channels began to disappear. If the device is new, then it may not have configured programs, so this fact should be clarified. But if the programs worked before, but disappeared in an instant, you should still go outside and see if the antenna has moved due to strong wind or something like that;

Sometimes the connection between the antenna and the cable, or the cable and the set-top box, is disrupted. If such suspicions arise, you need to make sure that the cable is connected to the LNB IN socket.

When none of the above list helps, there is only one way out - call for help. The master will definitely figure out what’s wrong and return your favorite programs.

Why are only 10 out of 20 digital channels shown?

Over the past two or three years, digital television users have often complained that after updating channels, half of the programs that were shown before disappear. Since then, people have a logical question: why did 10 channels disappear if they used to work and were free?

They are trying to find out the answer to this question on many forums, which is why different versions are put forward. For some, the channels of the first multiplex do not work, for others, the second. This suggests that the reasons for these troubles lie in various signal reception difficulties associated with technical work or features of the functioning of digital television.

Perhaps after some time the channels will restore their broadcasting, so you shouldn’t worry in advance about where ten popular channels have disappeared at once. RTRS clarifies that for now the work is being carried out in test mode, so for some regions such difficulties will become the norm. Sometimes searching for channels again or reflashing the set-top box helps, but if this is not your case, you can use analog or satellite television, where the signal works without such significant interruptions.

Note.

Many people face a problem when, after purchasing, their TV does not receive channels. Don’t immediately get upset and rush to return the product back to the store. Often, most problems can be solved on your own.

Digital broadcasting is a technology in which pictures and sound are transmitted using compressed encoded signals. This transmission method has many advantages compared to analog:

• excellent quality of transmitted picture and sound;
• immunity from interference;
• the ability to transmit a large number of channels;
• simple and quick setup;
• Internet access.

Reasons for the problem

In fact, there are many reasons why the TV does not find channels. Let's look at the most common of them:

1. Wrong UHF antenna type. It is possible that the antenna you have installed is not suitable for digital channels.
2. Incorrect direction of TV antenna. This problem may occur due to the location of the antenna in the opposite direction from the main broadcast station.
3. The receiver is disabled or faulty. This option is not excluded. It is worth carefully checking that the receiver is connected correctly, as well as its functionality.
4. Very weak signal reception. If, after checking all the previous reasons, you do not find any problems, it is worth checking your receiving device. It is possible that its signal is not enough to find channels.
5. Old firmware version. Outdated TV firmware can also create this problem. You can update the firmware yourself by downloading and installing required file from the official website of your TV model. If you have Samsung equipment, then you need to go to Samsung.com. However, we advise you to leave this matter in professional hands by contacting a service center.

How to fix the problem?

If you still don’t know why your TV doesn’t find digital channels, we’ll try to explain in detail the solution to this issue.

Connection methods

It is quite possible that this problem occurs due to incorrect connection method digital broadcasting. Each method has advantages and disadvantages. However, before you start searching for channels, you must connect the equipment correctly. Let's consider these options:

• Using a decimeter antenna. In this case, you need to connect the TV antenna and amplifier to your signal receiver, then connect it to the TV. Next, select auto search and wait for the result.
• Via cable. A large number of providers provide digital television services. Almost all modern TVs There are built-in signal cards. In this case, to receive a signal, just plug the cable into the socket and turn on automatic channel search. Of course, such a service is paid.

Search settings

It is possible that the problem lies in incorrect setting search. The setup scheme is almost the same on all TVs, so you should not have any difficulties. In this case, we recommend performing the following manipulations to ensure that the settings are correct:

1. Enter the “Settings” or “Broadcast” section.
2. Find the "Search for Channels" option.
3. Click on "Auto search" or "Auto setup".
4. Select your connection type (described above).
5. Select the Full search mode and the type of channels you want to search (analogue or digital).
6. Click Search or Scan.
7. Sort the found ones.

After that correct setting the search will be completed. If you are unable to receive more than one channel, we recommend reading the factory instructions for your TV or receiver. Perhaps you will find a solution to this problem there. As a last resort, you need to contact television setup specialists who will find and fix the problem.
