How to catch the reflected signal of digital television. How I set up terrestrial digital television. The state of digital television in Russia

Even as a child, living in the country, I always tried to tune the TV to good welcome a large number of 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 much, and some were not shown at all. Now, living in the city, you don't experience problems with the quantity and quality of the TV channels provided, but when visiting the village, sometimes you want to turn on the TV, switch channels by choosing 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:

1 Cable TV- television, in which the signal is propagated through a television cable that directly connects to each television

Pros: quality TV.

Cons: Subscription fee, available only in major cities.

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

Pros: quality TV.

Cons: Cost of equipment, subscription fee.

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

Pros: minimum costs.

Cons: often a low signal level, the 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, it worked for me only- use satellite TV, but I really didn't 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 of digital television is as follows - the transmission of television images and sound occurs by digital coding of a video signal and a sound signal using digital channels. Digital coding, in contrast to analog, ensures signal delivery with minimal loss, since the picture and sound are not affected by external factors (interference). From the nuances of using digital television, I will note the following - a television channel in digital television has two provisions, it will either work in good quality, or it will not 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 above 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 don't 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 similar case). 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 console. Another plus - no 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 the DVB-T2 set-top box or your TV has such a function). You can get more details 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, since technically they are all alike as two peas. Most of them have two outputs - tulip (some SCART) and HDMI, there is a USB connector for viewing uSB content carriers. 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 be using it constantly (switch channels, make the volume quieter, higher, etc.).

I connected the antenna to the DVB-T2 set-top box, and using 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 mono 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, 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 from 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 to do 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 channels 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, to watch all 20 channels, I purchased a high-quality, "strong" antenna. Test video below.

ANT-T2-MAX Antenna Test Video

In order to understand the capabilities and settings of this console, 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 with USB stick... To do this, insert USB device into the set-top box, go to the menu, select "USB" - "Multimedia", select the format to play (music, pictures, video).

In addition, digital set-top boxes have the ability to record images from the 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, more channels are possible, 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.

Thanks to the development of digital terrestrial television in Russia, almost all residents of the country today have the opportunity to watch 10 federal TV channels for free. And about 65% of Russians “catch” 20 channels on their TVs for free. The list of channels of terrestrial digital television includes: Channel One, Russia 1, Russia K, Russia 24, OTR, TV Center, NTV, REN-TV, TV-3, Channel Five "," Match TV "," Carousel "," Muz-TV ", STS, TNT," Friday "," Domashny "," Spas "," Mir "and" Zvezda ".

Digital terrestrial television can be connected on TVs supporting the DVB-T2 standard, as well as on older models using a special set-top box, for example, Wifire. The device can be rented for 99 rubles a month or bought for 3900 rubles. It's easy to set up, has no extra wires as it connects via Wi-Fi, and is compact and you can easily find a place for it.

The installation of a TV antenna available to all viewers makes it possible to receive digital television in Moscow, broadcasting is carried out in the dvb-t2 standard. The analogue broadcasting system is a thing of the past and will be completely disabled in the near future. The reason for this is the improvement of radio frequency technologies. If earlier there were no more than 18 programs from the Ostankino tower, then in 2016 there are already 30. The channels work digitally and are grouped by 10 at one frequency, such a package is called "Multiplex".

1. The first multiplex Ostankino TVK 30, frequency 546 MHz
2. Second multiplex Ostankino TVK 24, frequency 498 MHz
3. Test third multiplex Ostankino TVK 34, frequency 578 MHz

For local repeaters, the broadcast parameters may differ. The decree of the Government of the Russian Federation assumes the widespread launch of twenty federal, free channels... Towers under construction and operating in the Moscow region can be found in the right block of the current page.

Pros of terrestrial digital television

Maintenance free

Television, installed in compliance with all the rules, serves for a long time without service maintenance.

A large number of TVs can be connected to one antenna with a daisy-chained cable.

Digital quality

Image without interference and distortion with digital system DVB-T2 transmission and support high resolution.

No monthly fee

Free TV shows all federal channels, 20 programs are officially launched and 10 are in test mode.

Reception of digital television in Moscow is possible on any TV, with the difference that older models will need a dvb-t2 receiver. This is a small attachment with a separate remote control through which control is carried out. The signal from the antenna is fed to the receiver, and you can connect it to the TV with a tulip or scart cord. How to set up the receiver is described in the user manual. In newer types of flat panel TVs, the tuner is already built-in, look for the dvb-t2 in the specifications and try to find digital channels... If it does not work, check the cable connection and find out if you have a usual cable TV.

The main part of the set of equipment is the antenna, the quality of terrestrial television reception depends on its power. For Moscow, usually, an antenna with a medium gain is enough. In some cases, a more powerful option is required. This happens when a country cottage a private house or the cottage is located in a lowland and surrounded by tall trees. The distance to the tower also plays an important role. Installation is desirable in the highest part of the house, installation is carried out on a small bracket or steel mast. The price of work will vary depending on the complexity, the exact cost is calculated by the master using the standard price list, taking into account current discounts and promotions. Connection is made to existing cabling using an amplifier and dividers. The master can arrive the next day after receiving the order.

Do you want to watch your favorite TV channels in high quality for free? Use the service of digital terrestrial television DVB T2. In many countries, this standard has already become the main one over the past few years. Unfortunately, in Russia it is just beginning to gain popularity. Today, 20 of the most popular Russian channels are already available, and in the near future the organization responsible for the development of technologies promises to add another package of channels.

If for cable TV you need to pay a regular monthly subscription fee, then the benefits of digital terrestrial television are obvious - having paid only once for a set of equipment, after about a year its cost is fully paid off and in the future you watch TV for free. In addition, you rarely need the entire package of channels that are provided by cable or satellite providers.

In today's article, we will tell you in detail what features the DVB T2 digital terrestrial television service has, as well as what is needed for self installation and equipment settings. Once armed with the knowledge, the installation of terrestrial antennas will be very simple and you can save significant money by not calling the master. So let's get started.

More recently, terrestrial television was associated with poor image quality, a large number of various interference, and a minimal set of channels. It was necessary to manually tune each frequency separately, while different channels could operate in different ranges, which led to the fact that it was necessary to install several antennas or one multiband. In some cases, and along with the signal, additional Information, for example, teletext, when it was possible to receive information about a TV program or various entertainment content directly on the TV screen. Today, in the era of the Internet, such additional services have lost their relevance, but in the era of high-quality video and high-resolution screens, a high-quality television picture has become more in demand than ever. Therefore, a digital television standard was developed.

It was the use of digital technologies that made it possible to reach a completely new level quality. If earlier for this it was necessary to use exclusively satellite television, which entailed additional installation difficulties, and the set of equipment was not affordable for everyone, now it is enough to install and configure an almost ordinary decimeter antenna, in some cases an amplifier, as well as a TV set-top box. And if you consider that many modern TVs already have a built-in DVB T2 receiver, you can get by with just one inexpensive antenna.

Let's take a closer look at the advantages and disadvantages of T2 digital terrestrial television.

Benefits:

Despite the huge number of advantages, there are a number of certain disadvantages:

The state of digital television in Russia

In a way, Russia has lagged behind other European countries. Their television format DVB T2 long ago became a generally accepted standard and in many places analogue broadcasting is not conducted at all. In Russia, today there is a transitional stage, when everyone realizes the need to abandon analog televisionbut the digital infrastructure is underdeveloped yet. In general, in most large cities you can easily catch the number, but if you live in very remote regions, you will either have to be content with one multiplex, or just be patient. Fortunately, there are practically no such places left, the signal covers by and large all settlements.

Now let's talk about filling channel packages or, as they are officially called, multiplexes. Today there are 2 multiplexes broadcasting 10 channels each. In the coverage area of \u200b\u200bdigital terrestrial television DVB T2, reception of the first multiplex is guaranteed, while the second is not yet available everywhere. There are talks about the launch of the third package, but due to the lack of frequency resources and the need to free up frequencies for it by disabling analog broadcasting, the launch date is still unknown.

What channels are included in each of the packages? At the beginning of May 2017, their composition is as follows:

Please note that the content of multiplexes is not constant and changes from time to time. This has happened several times over the past few years. In any case, the set is quite diverse and channels are provided for every taste and for every audience.

Necessary equipment

So, what equipment do you need to purchase to watch digital terrestrial television DVB T2? Depending on the equipment you already have and the distance from the transmitting center, you may need the following set:

Antenna installation

It is almost impossible to list all the special cases and conditions of admission in one article. Therefore, we will give only general recommendations that should be taken into account when installing an antenna for digital television DVB T2.

Room

Place the antenna on a windowsill and turn it towards the transmitting tower. Make sure there are no radio signal sources nearby, such as a Wi-Fi router. The distance between them should be at least several meters.

Outdoor

Outdoor antennas also need to be turned towards the tower and securely fastened so that wind or other weather conditions cannot disrupt its position. It is best to first install a reliable bracket and attach it to the wall or roof of the house, and then attach the antenna to it. This will allow you to vary the position of the device. When installing, be sure to note that for fine tuning you will have to rotate it, so do not fix it immediately, it is better to do this after the complete installation is complete.

• Don't rush to use the amplifier. Try experimenting without it at first. Twisting the antenna or moving it slightly to the side can sometimes help a lot. If all else fails, only then use the amplifier.
• If you plan to use several TVs, the antenna must be outdoor. By the way, in this article you can find out how to connect multiple TVs to one antenna.
• Minimize situations where the signal is shielded or blocked. For example, do not place the antenna under a metal roof or near a multi-storey building that blocks a tower, as well as high-voltage lines. True, in some cases, you can use the signal reflected from a tall structure and amplify it with an amplifier.

Fine-tuning the signal quality

You can, of course, accurately catch a signal of proper strength and quality yourself, without the use of additional equipment. Nevertheless, in conditions of difficult reception, it is best to use a special device for tuning terrestrial antennas. What is such a device? This is usually a small box with a mechanical dial or LCD display that displays the signal strength. On the one hand, the power is connected, and on the other, an input for connecting the antenna cable is provided. Since tuning the antenna according to the visual perception of the image on the screen is not the most reliable, such a device will greatly simplify your task.

1. Take the device and connect to it antenna cable, and also supply power either from the built-in batteries or from an external battery pack.
2. Turn the antenna towards the receiver. In the case of correct directionality, the device will immediately begin to emit sound signal, and on the scale, numbers or an arrow run in.
3. If the device shows insufficient signal strength, change the position of the antenna by turning to the side, raising it higher or lowering it lower. Maximize your signal performance.
4. Turn off the device, fix the antenna and you can start setting up the equipment.

Connecting the antenna to the TV

With a built-in DVB T2 receiver

1. Find a dedicated connection port on your TV external antenna... He is usually signed by Ant In.
2. Connect the cable from the antenna to this connector. During this time, the TV must be turned off for safety reasons.
3. Turn on the TV and activate the digital tuner in the settings.
4. Execute automatic search channels.
5. Enjoy watching.

When using a digital set-top box tuner

1. Connect the cable from your antenna or amplifier to antenna input on a set-top box.
2. Connect your TV box to your TV. Ideally this should be an HDMI cable as it provides the highest video quality. If this interface is not available, connect the two devices using traditional analog connectors, called tulips. There should be 3 of them, they are indicated different colors... These are usually yellow, red and white. Two of them are audio connectors, while the third is video. Most often, the connectors on both the TV and the set-top box have the same color designation, so it is rather difficult to confuse them.
3. Turn on the TV and using the remote remote control select the external signal source to which the tuner is connected. It can be either HDMI or AV. It all depends on the connection method.
4. Search for TV channels automatically or tune each one manually.

Conclusion

We showed you a detailed step by step guidehow to install and configure digital television DVB T2. Now you can easily watch up to 20 free channels. If you still have questions, or something does not work out, ask in the comments or contact our masters.

Tuning antennas, one of the stages of the installation process. It concerns how satellite equipmentand digital. In the previous article, I wrote what equipment you need and how to install it correctly. We have already determined in which direction the nearest digital television repeater is from us. Now I will tell you how to set up an antenna using a TV or dvb-t2 set-top box.

Getting started setting up

After you have installed the antenna approximately directed it towards the TV tower, mounted the equipment and made the cable routing around the house, we proceed to set up terrestrial antenna... For this we need parameters broadcasting, in other words, look at which TVK number or frequency the package of TV channels is transmitted from your repeater.

There is nothing special to write about the methods of receiving digital TV, I will only remind you that outside the city we mainly catch a straight line, but in the city you can also catch a reflected signal. This will not change the setting principle.

Tuning using a TV or set-top box

To set up a TV antenna, we need a TV with a built-in dvb-t2 receiver or a set-top box for digital terrestrial television. Connect the cable coming from the divider, amplifier, TV outlet to the antenna socket of the TV, turn on the TV and go to the manual search for digital stations (channels). In approximately the following way (for example, a sony TV receiver is taken), but the search principle is similar on other TVs:

Press the MENU or HOME button on the remote control - installation - channel setup - digital configuration - digital setting - manual search for digital stations. As a result, the scales appear for the level and quality of the signal.

Using digital set-top box from dvb tuner t2 the principle of tuning the antenna for digital TV does not change. Insert the TV cable into the receiver's jack, and connect it to the TV in turn.

Turn on the equipment, remember to switch the TV to the input jack of the receiver. To do this, find the button on the remote control:

• SOURCE;
• INPUT;
• AV / TV;
• TV / VIDEO.

If there is no such name, then we are looking for a button with the image of a circle or rectangle with an arrow inward. On the remote control from the console, press the menu button on the screen, the receiver menu should appear. For more details about connecting the set-top box, read on our website. Next, go to manual search as on the TV.

It's easier to press on the console. Menu - search - manual search.

On some TV models, decoders in manual search, we need to set the UHF (UHF) range and the channel number on which the repeater is broadcasting. If everything is done correctly, a signal will appear on the scales. Now we need to make fine tuning (adjustment) of the signal quality.

If you set up a TV antenna to receive digital TV yourself and do not have a tuning device, then you may have to pull the equipment to the antenna to see the scales on the TV. In order not to lug equipment, call someone for help. In this case, you leave the assistant to observe the scales on the screen, and you yourself climb to the antenna and begin to turn it to the right or left. We keep in touch with the assistant by phone. We turn the antenna slowly, as the scale on the screen will be displayed with a slight delay. After you achieve the maximum signal quality on the set-top box or TV, fix the antenna in this position and search for channels on the equipment.

Possible mistakes

The signal rises smoothly and then drops to zero - there is not enough signal strength.

• We try to raise the antenna slightly higher or shift it to the right or left.

There is no signal on the scales.

• We check all connections.
• If an amplifier has been installed, check to see if it is plugged in.

When using a prefix, there is no signal on the screen.

• Check the set-top box is matched with the TV. (even if you have not plugged the antenna plug into the receiver, you should still see the menu).
