The broadcasting of the Ostankino tower has finally switched to the new DVB-T2 standard - digital channels are no longer shown in DVB-T format. Residents of the city of Moscow and the Moscow region have turned off broadcasting since January 15, 2015, the analog range continues to broadcast as usual. The loss is associated with the program "Development of TV and Radio Broadcasting in the Russian Federation for 2009-2015", signed by Dmitry Medvedev back in 2009. The bottom line is the transition to a digital system from an analog one, this will make it possible to receive high-quality broadcast in all regions of Russia. Most television viewers from the provinces do not show more than one or two programs, and if they do, the picture quality leaves much to be desired. The transition program will be implemented in stages and until more than 95 percent of the viewers are ready to accept the figure, complete shutdown no analogue will happen. TVs that only support DVB-T will not be able to receive 10 channels in digital. Those who have lost digital channels will need a built-in DVB-T2 tuner or a digital set-top box to watch terrestrial television. The previously installed antenna does not require replacement.

Digit broadcasting in DVB-T disappeared

What to do if digital channels are missing? It is not necessary to change the TV set, especially since most often it was bought not so long ago. You need to buy a special tuner and connect it to your blue screen using an HDMI or RCA cable (tulips, bells). It's bad that there will be an additional device next to the TV and you will have to use two remotes, but it's still cheaper than buying a new one. Digital channels are not shown on old-style tuners, please note that DVB-T2 is indicated in the characteristics. The number of major federal programs has reached twenty, and their number will increase in the future.

At the beginning of 2015, it has been consistently showing 20 channels, of which two are broadcast as high resolution HD - First HD and Russia HD. To view HD, the connection must be made with an HDMI cable, not RCA (tulips) or SCART (comb). Another 10 channels are being received in test mode. Total - in Moscow and the Moscow region shows 20-30 digital channels, disappeared only in DVB-T... should be carried out by specialists with professional instruments and equipment. You can call the master from us, the service area is Moscow and the Moscow region.

Even as a child, living in the village, I always tried to tune the TV to a good reception. a large number channels. The only option that I figured out for myself, from these attempts, the higher the antenna is, the better quality channels and more. But there is a limit to the height of the antenna mast. Therefore, some of the channels were always shown well, some were not shown very well, and some were not shown at all. Now, living in the city, you do not experience problems with the number and quality of the TV channels provided, but when visiting the village, sometimes you want to turn on the TV and switch channels choosing an interesting program. But in the village, time flows more slowly and modern technologies come there with a delay, and sometimes do not come at all.

In this regard, I set myself the goal of setting up as many television channels in the village as possible. To begin with, I propose to consider what options are available today to get a high-quality signal and picture on the TV:

1Cable TV- television, in which the signal is transmitted through tv cable that connects directly to every TV

Pros: high-quality TV.

Cons: Subscription fee, available only in major cities.

2 Satellite television. Satellite TV broadcasts by means of a satellite "suspended" in near-earth orbit. The signal is received by viewers on an individual "dish" antenna.

Pros: high-quality TV.

Cons: Cost of equipment, subscription fee.

3 Terrestrial television... Terrestrial television broadcasts a signal using terrestrial repeater stations, in order to receive this signal it is necessary to use an antenna.

Pros: minimum costs.

Cons: often low level signal, display and quality of channels depends on the weather, distance from the tower, mast height, etc.

You can also say that TV channels can be watched over the Internet, but in this article I would like to talk about watching channels without using a computer / laptop, and even more so the Internet.

Of all the methods described, only the use of satellite TV was suitable for me, but I really did not want to spend money on the purchase of equipment, and then pay a subscription fee. Having rummaged through the Internet, I found an alternative way- terrestrial digital television... The essence digital television in the next, the transmission of television images and sound occurs using digital coding of the video signal and sound signal using digital channels. Digital coding, unlike analog, ensures signal delivery with minimal loss, since the picture and sound are not affected external factors(interference). From the nuances of using digital television, I will note the following - for a television channel in digital television, there are two provisions, it will either work in good quality either won't work at all. Unlike analog TV, there is no borderline state and interference, the only exception is if the channel has very poor communication quality, it can slow down, turn off and turn on again, in order to avoid this, you need to use another antenna, raise the existing one higher or turn towards the TV tower ...

What you need to watch digital TV:

TV antenna;

TV or Set Top Box with tuner DVB-T2(namely DVB-T2, outdated DVB-T will not work), support for the MPEG4 video compression standard and the Multiple PLP mode.

You do not need to buy an additional antenna, just use the antenna to analog signal... But the antenna itself is not enough, to watch digital TV you need a set-top box with a DVB-T2 tuner (some modern TVs do not need such a set-top box, since it is built into the TV, this information can be obtained from the documentation for the TV or on the manufacturer's website, in which a similar case is considered ). Set-top boxes are not expensive on average from 1500 to 2000 rubles. In fact, you don't need to buy anything other than this set-top box. Another plus is that you do not need to pay a subscription fee for digital terrestrial television.

It is important to note that digital TV allows you to watch a limited number of channels, at the time of this writing, there were 20 of them (perhaps less depending on the region of residence).

Digital television is not tuned according to the principle - the higher it is raised, the more it is caught. You can only tune these 20 channels, plus you can add more analog channels that your antenna will catch (if your DVB-T2 set-top box or your TV has such a function). You can get more detailed information about the number of channels and the possibility of using digital television in your region by phone hotline RTRS: 8-800-220-20-02 (free call within Russia) or on the website: www.rtrs.rf.

So, I propose to move from theory to practice. In my case, the usual TV antenna, which was very popular 15 years ago. On this antenna, I managed to catch about 3 analog channels in good quality, 2 in satisfactory and a couple more channels appeared in poor quality in good weather.

I purchased a DVB-T2 set-top box. Regarding the choice of consoles, I did not rack my brains, because technically they are all alike as two drops of water. Most of them have two outputs - tulip (some have SCART) and HDMI, there is a USB connector for viewing the contents of USB media. I got the impression that they are all made at the same Chinese factory, only equipped with different boxes and labels. When buying, pay attention to the control panel of the set-top box, since you will use it constantly (switch channels, make the volume quieter, higher, etc.).

I connected the antenna to the DVB-T2 set-top box, and with the help of a tulip (it usually comes with the set-top box) I connected it to the TV.

Tulip - RCA connectors for video and stereo sound. Yellow is for video, white is for monaural or left channel for stereo two-channel audio, red is for right channel for stereo two-channel audio.

I'll make a reservation right away that I connected the set-top box to an outdated CRT TV, so I chose a tulip cable, if you have an LCD or plasma TV with HDMI output, then you should connect with a nominal HDMI cable (it must be purchased separately), since the image quality will be much higher.

I switched the TV to AV mode and got to the interface of the DVB-T2 set-top box. Setting up the set-top box requires a minimum of effort, all default settings will suit most users. The main thing that needs to be done is to configure the channels. To do this, I went to the channel search menu and selected Auto search.

A few minutes later, the DVB-T2 prefix found the same 20 channels + 3 radio stations. But after a few days from 11 to 20 channel disappeared, on the website rtrs.ru I saw that the towers to which I connected did not support 2 multiplexes (channels 11 to 20), and the fact that they worked for a couple of days was most likely tests. As a result, for viewing all 20 channels, I purchased a high-quality, "strong" antenna. Test video below.

Antenna test video ANT-T2-MAX

In order to understand the capabilities and settings of this set-top box, I offer a photo of each of the menu items (I apologize for the low quality of the photo).

A digital set-top box, as I wrote earlier, can play files from a USB flash drive. To do this, insert the USB device into the set-top box, go to the menu, select "USB" - "Multimedia", select the format to be played (music, pictures, video).

Besides, digital set-top boxes have the ability to record an image from a TV to a USB flash drive. To do this, it is enough to press the "Rec" button on the DVB-T2 control panel of the set-top box, after which the recording will go to the USB device.

To summarize, I am very pleased with the quality and number of digital TV channels (of course, you can more channels, but not all at once). In my opinion, for remote places, summer cottages, villages, settlements where people are not ready to spend 10,000 rubles to purchase satellite TV + pay a subscription fee, I think this option is the most suitable.

Quite a lot of people are faced with such a very unpleasant situation when they buy a new TV, and that one does not catch digital channels. But digital television broadcasting is the technology of the future, and very soon all TV channels in our country will only switch to this modern format. Do not be alarmed that your TV turned out to be unsuitable for receiving digital television, since most of the problems due to which the TV does not pick up these channels can be eliminated. Let's consider them in more detail.

  • You are not using a cable or satellite box. Don't worry that without this device you won't be able to watch digital channels. You can, but first you need to find them. To do this, first of all, you need to make sure that antenna cable connected to the TV. We go to the TV menu, and select the channel search item, which is usually located in the configuration folder. The TV starts searching for digital channels to be added to the analogue channel list.
  • The signal from the antenna may be too weak. You need to purchase another antenna that is more powerful.
  • It is possible that your TV does not support the broadcast format adopted in Russia (this happens especially often with TVs that are not intended for the domestic market). In this case, you need to contact specialists who can determine exactly whether it is possible to reflash this TV model so that it can receive Russian digital channels.
  • Your TV does not support the new digital TV format. This is directly related to the fact that the Russian government decided to postpone the start of broadcasting digital terrestrial TV in the DVB-T2 format to 2012. Thanks to this decision, in those regions of the country where DVB-T2 was not introduced in parallel with DVB-T, but replaced it, televisions of almost all manufacturers stopped receiving digital terrestrial TV. In order to watch TV in DVB-T2 format, you need to purchase an appropriate receiver. However, for example, residents of Moscow were not affected by this problem, since the Moscow authorities found an opportunity to keep broadcasting in DVB-T format in parallel with DVB-T2.
  • Your TV's firmware is outdated, and even though you can watch digital TV, it cannot cope with this function. To fix the situation, you need to reflash the TV. You can do this both yourself, by downloading the firmware from the manufacturer's website, and from specialists who repair TVs. Trying to save money at the risk of breaking your TV or trusting professionals is only yours.

In fact, there are a lot of reasons why the TV does not pick up such channels, and we have given only the most common of them. Therefore, if your TV does not want to catch digital channels, then it is best for you to contact the TV Service Center company. This is really the optimal solution, since our masters will help you in any situation, they will carry out accurate diagnostics and eliminate the malfunction of your TV as soon as possible. And you do not need to take your TV anywhere - specialists will come to your house.

Set-top boxes for receiving terrestrial digital TV format dvb-t2 allow you to watch TV in excellent quality with good picture, sound and no interference. Moreover, all this is pleasure without any monthly fee. In addition, they can be connected to old TVs via a regular audio / video input or hdmi (if the TV set is more modern). Or even a computer. But for this, in some cases you will need an adapter from hdmi to vga.

Despite the fact that coverage of terrestrial digital TV in Russia is carried out almost everywhere, in some cases there is no reception of channels. In this regard, people have a question: why the set-top box for digital television dvb-t2 does not find TV channels, and the inscription "no signal" is lit on the screen. There may be several reasons for this. Let's figure it out. Let's start with the simplest reasons.

First of all, check if you correctly connected the set-top box to the TV and whether the antenna is connected to the dvb-t2 receiver itself. It would seem that they are banal simple things, but it still happens that at this stage something is done wrong.

And if everything is connected correctly, then you need to find your locality, and see how far the nearest TV tower is from it. It is also important to pay attention to whether it is active or only under construction. Although, most likely, the first multiplex is already being broadcast. The very same problem in the absence of TV signal reception may be that the tower is far from you. Because of this, the receiver does not find channels. Signal too weak. And here you need to arm yourself with an active external antenna (which is with an amplifier), or build an antenna called a biquadrat. There are many videos on YouTube on how to make a biquadrat correctly.

Part of the problem may be related to the fact that a weak receiver is installed in the receiver itself. The more expensive dvt-t2 set-top boxes use more powerful components.

In any case, if the TV tower is at a distance greater than the line-of-sight distance, you will have to experiment with the antenna. But, as a rule, repeaters are built in such a way as to cover as many settlements as possible.

Another commonplace reason for the absence of a TV signal may be that some preventive work and it's just disabled. If it is off, then the red light is off. Although this can only be noticed at night.

Another frequently asked question: why does it show only 10 digital channels, and not 20? And the answer is very simple: in your region, this moment only the first multiplex, which includes the first ten federal channels, has been launched and is operating, and the second multiplex with the second ten is just being built. In this case, you just need to wait a while.

Today it is difficult to imagine life without television broadcasting. No signal is a fairly common problem that most TV owners face sooner or later. There may be several reasons why this malfunction may occur. These include, first of all:

  • hardware problems;
  • preventive work;
  • external factors.

The most common reasons why your TV is not receiving a stable signal from this category tend to be:

  • defect in the connecting cable;
  • malfunction of the satellite dish or antenna;
  • failure of the satellite converter.

A problem with connecting cable can be a very obvious answer to the question of why there is no signal on the TV. If the antenna or satellite dish has a poor connection with the device due to damage to the cable, this situation is quite justified. Check the plugs and the wire itself for defects. By the way, the quality of the wire itself also affects the transmitted signal, so it will not be superfluous to know.

If you use a satellite dish to receive a TV signal, you need to make sure that it is in correct position(below we will give a tip on how to do this) If the satellite receiver is covered with a layer of dust, ice or dirt, it is not surprising that it does not work. In this case, carefully clean the surface.

Malfunction satellite converter is a fairly common reason why there is no satellite signal on the TV. The converter acts as a regulator that lowers the frequency of the satellite signal to reduce signal transmission losses. In order to solve the problem, replace the faulty converter with a new one.

Important: if you are not sure that you know how to perform such manipulations with satellite dish- entrust this business to an experienced master. Otherwise, you risk causing irreparable damage to the device.

Preventive work

If your TV says “no signal” in extremely rare cases, it is possible that your operator is carrying out preventive work to eliminate delays and other problems in TV signal broadcasting. The only way out of this situation is to wait until the preventive work comes to an end. It is quite simple to distinguish one reason for the absence of a signal from another:

  • take the remote control from the receiver;
  • enter the system menu;
  • check if there is an inscription "no signal" in the receiver menu.

If the device starts to write about the absence of a signal in its system menu, it means that the problem lies in the satellite of your operator... In some cases, the set-top box may "hang" (for cable TV subscribers). Try to reboot the device: disconnect it from the network, and after 30 seconds, turn it on again. Perhaps the problem will go away. The same actions can be done for.

In any case, it will not be superfluous to contact your digital TV provider to find out what to do in this situation.

External factors

How to set up a satellite dish yourself

To make the setting satellite dish with your own hands, you must:

  • go to the operator's website and find an angle calculator;
  • enter the coordinates of the satellite and find out your location;
  • aim the antenna at the satellite using the data obtained earlier.

Define your current location can be done using a regular smartphone. As a rule, their accuracy is sufficient to select the optimal direction of the tray.

If you often have problems with no signal, then information on methods will come in handy. This may require. In any case, this is a solvable problem, both for old TVs and for new ones.
