Interactive map of digital television. Ways to receive a digital signal

federal program It is planned to cover the entire territory of Russia with digital television by 2015. Already today, many regions of our country can enjoy high-definition television in HD format. But this pleasure is not available to everyone (everyone can watch, but not everyone sees))).

How to find out if your area has DVB T2 signal coverage

Very simple! To do this, go to the official website of the federal project, in the section " Map of network coverage". You get an interactive map where you can find your location or the nearest settlement by entering them into the search bar and selecting from the drop-down tips:

At first glance, nothing complicated, but there are some nuances did on the knee and did not explain how to use it ) . Let's focus on the right upper corner digital TV cards, and see what's there.

By default, the checkbox " Broadcast points"- in fact, these are the TV towers that broadcast in DVB T2 format, and package of TV channels RTRS-1. This, that is, the first ten information channels digital television. To see if you are in the broadcasting zone of the TV tower, check the box “Broadcasting zones”, as well as “TVK, frequency”, the map will be painted in cheerful colors:

"Green" towers are working. Here is the frequency and channel number on which the signal is transmitted

If your area is painted, and there is a "green" tower nearby, then everything is probably fine. By at least, you will definitely catch the first ten channels. The frequency of the towers will come in handy when, so remember it, or rather write it down, like the channel number on which your “number” is broadcasting.

But that is not all.

The fact is that the first and second multiplex are transmitted by different towers and at different frequencies.

This means that, for example, the first ten channels can already work for you, but the second ten - the tower is still being built, and this often happens. It is easy to check this, go to the "RTRS-2 channel package" tab:

The second multiplex - as you can see, there are much fewer "green" towers

We will be shown the towers again, and, most likely, not all of them will be green, as in the first case. Since the first towers were built for the first multiplex, they have been built for a long time and broadcast the first ten channels. But with the second multiplex worse. However, if there are no "green" towers near you, do not despair, click on the gray ones, there will be information about the stage of construction and approximate commissioning.

From personal experience I will say that the mother in the region has the first multiplex arriving from the tower 10 km away, but the second one arrives from the neighboring region, 45 km from her house. Indeed, it uses outdoor antenna"dryer", with an amplifier, on a high pole. Naturally, without an amplifier, she does not catch anything.

We get detailed information along the tower. At least it's already built, which means it's about to launch!

At times they slip friezes". However, judging by the map, a tower with a second multiplex is being built nearby, so everything will be fine soon.

I hope now you have figured out how to determine the coverage area of ​​digital television, and have learned how to correctly interpret the digital TV map on the official website of the project. It's time to move on to the next step.

Moscow is one of the first cities in Russia where terrestrial television broadcasts began in digital format. Until 2015, Muscovites could receive a TV signal in DVB-T format. Now you can watch on-air "figure" only if you have equipment that supports the DVB-T2 standard. The network of RTRS transmitting stations provides reception of the first 10 channels (the 1st multiplex) practically throughout the entire territory of the Moscow Region. Broadcasting of both multiplexes (20 channels) is carried out for 2016 only from a few TV towers: the Ostankino TV tower and towers in the cities of Shatura, Aleksandrov and Obninsk.

frequency map

Traditionally for the RTRS network, digital broadcasting in the Moscow region is divided into many single-frequency zones. This means that within each zone multiplexes broadcast on the same frequency. On the frequency map, you can indicate the broadcast frequencies of the first multiplex in different parts Moscow region. For information about the frequencies of the second multiplex, you can use the interactive map of digital television. Using the map, you can not only find out the frequency of the transmitter, but also the distance to it from a specific place and the direction of the antenna.

Coverage area of ​​the second multiplex in Moscow

As mentioned above, as of 2016, all 20 channels were broadcast from only four repeaters. Understanding the desire of viewers to watch as many TV channels as possible, we have placed on the website the calculated coverage areas of the TV towers, which broadcast both digital multiplex DVB-T2. Despite the fact that the accuracy of the calculation is quite high and takes into account the terrain, the actual coverage pattern may differ from the calculated one. You can also use the height profile building service. With its help, you can determine the terrain from the TV tower to a specific reception point with high accuracy.

Third multiplex in Moscow

Peculiarity digital broadcasting in Moscow is the broadcast of the third multiplex digital TV channels since January 15, 2015. Like the first two, the multiplex consists of ten DVB-T2 TV channels. Of the channels "Sport 1", "Lifenews" and "Our Football" occupy permanent positions, and on the remaining seven channels, numerous thematic projects share the air. The third multiplex is also broadcast without the use of the system conditional access and any pay-per-view. Thus on this moment this is the only opportunity to watch "Our Football" for free. The package of channels is broadcast only from the Ostankino TV tower on the 34th frequency channel.

After the advent of digital television, many users wanted to switch to its reception. It's not just about frequent discussions and the desire to try something new. Signal quality is an order of magnitude higher, and ease of access increases attractiveness. It is possible to connect digital TV to outdated kinescope models with the help of additional devices, and to modern TVs.

Ways to receive a digital signal

There are several ways to connect quality signal for TV:

1. Cable TV. Reception is carried out via a common cable. The downside is the subscription fee and not ubiquitous availability;
2. Satellite television. Signal transmission is carried out through satellites, and reception is carried out using an individual dish. You also need a monthly fee plus the purchase of special equipment;
3. Broadcast television. The digital TV signal is distributed from terrestrial repeaters, you can receive it from an antenna, indoor or outdoor. It's perfect free method watching TV shows in a modern format. It has disadvantages: often a low signal level, the quality of the picture can be affected by the weather, the location of the tower, etc.

The least expensive way is to receive digital television through an antenna installed and configured by the user.

How digital television works

The transmission of picture and sound for digital television is carried out by encoding the video signal and sound over digital channels. Digital encoding differs from analog in immunity to interference (external obstacles). A blurry, fuzzy picture, stripes are impossible here. The image is either clear or completely absent.

If the reception is uncertain, then perhaps the picture will break up into squares, disappear and reappear from time to time. It depends on how you set up the antenna. Alternatively, you can install a different antenna or raise and deploy the existing one, pointing at the TV tower.

Required viewing equipment

1. Antenna;
2. A separate set-top box with dvb tuner T2, which supports the MPEG 4 standard and can operate in Multiple PLP mode.

Antenna can be used conventional analog. If the TV was released relatively recently, then it may have a built-in tuner desired format(outdated DVB format T is no longer supported). Then you don't need to buy anything else.

To find out if there is a built-in DVB T2 tuner, you can look at the data in the data sheet. It is even easier to find a TV model on the Internet and get a comprehensive answer.

Selecting a digital tuner

At first glance everything set-top boxes are the same. The main thing is not to make mistakes in the main technical specifications. But there are other features that affect further work equipment and breadth of functions covered:

1. No buttons on outer panel set-top boxes will oblige to use it only with the help of the remote control, which is not always convenient;
2. If the tuner does not have a USB port, this technique cannot be used as a media player. If available, you can record TV shows and play photos, videos.

Important! A good choice is a set-top box with a separate power supply. It is usually built in. The most common cause of tuner failure is a power supply failure. If it breaks, you need to repair or replace the entire prefix, and the remote power supply must be replaced separately without problems.

Many hang the TV on the wall, and quite high. Then it is inconvenient to use the usual design of the prefix. There are equipment modifications - compact set-top boxes that are attached to the back of the TV with adhesive tape. The strength of the attachment must be considered. Such a receiver is controlled by a remote control through a separate sensor attached to the same adhesive tape on the outer panel of the TV. Power comes from the TV's USB port.

The set-top box can also be used in conjunction with a computer monitor (if there is an HDMI port). Then you can watch digital TV from a conventional antenna. If the built-in TV tuner fails, it can be easily replaced using the receiver.

What channels are available to watch

To view free digital channels via a conventional antenna, the 2017 list contains two multiplexes:

• the first RTRS 1 - frequency 546 MHz, channel 30;
• the second RTRS 2 - frequency 498 MHz, channel 24.

Technical data are valid for Moscow and the region. They may differ in other regions. A total of twenty television channels and 3 more radio programs are available.

Important! TV does not pick up additional channels. Antenna tuning will not affect the number of received channels, but only their quality.

How to locate a TV tower

Users living in the city, in the signal reception area from the TV tower, are not puzzled by such questions. But for the inhabitants of remote towns and villages, the information is relevant. What knowledge is needed to best choice And correct setting antennas:

1. The exact location of the tower and the distance to it;
2. Technical parameters (channels and broadcasting frequencies), using which you can catch a digital signal in a given area. This is necessary for the user to manually tune TV channels on the set-top box;
3. Is the entire list of channels available for reception. There may be one or two packages.

Full information about the TV towers is on the official website of RTRS. There are maps where you need to search string enter the name of a specific locality. A map of the area will immediately open, on which all transmitting TV towers are indicated (green - operating, black - under construction). If you click on the cursor hovering over the selected village, information will be available on where and for how many kilometers operating transmitters are installed, channel numbers (TVK), broadcast frequency, number of packages).

The active menu includes a function that allows you to find out the coverage areas of individual repeaters.

Now, armed with knowledge, it is necessary to determine whether it is enough to install an indoor antenna or whether an outdoor, more powerful one is required.

Antenna types

The analog signal is received at the MV antenna. DVB Antennas are more compact. There are combined samples capable of receiving both ranges. From such a combined design, one can remove unnecessary elements, and you get an excellent UHF antenna. For example, if there is a long whisker (an element for the MV signal), they can be removed.

All antennas are divided into:

• active;
• passive.

Active devices are those in which amplifiers are used. The antenna with the amplifier must be connected to a power source. If a receiver is used, the 5V power for the amplifier is supplied through it. This is done in the menu settings. The option is called Antenna Power.

Amplifier does not always mean best reception, in some cases its use will even hurt:

1. In the area next to the TV tower, turning on the amplifier can lead to the complete disappearance of reception due to too strong a signal;
2. The amplifier is the weakest element of the antenna, often failing. Plus a power supply and additional wires, which also require repair and replacement;
3. The intensity of the TV signal itself is provided by the design of the antenna. And the amplifier in parallel increases the level of noise and interference;
4. If you want to connect another TV to a passive antenna, this is easier to do.

Passive structures do not have additional amplification, they are usually used in areas with a stable signal.

Antenna selection and installation

An old antenna may be suitable for reception digital signal, if it consists of short elements or combined. If there are working serviceable antennas, it remains only to find out whether they will effectively catch the "figure" in local conditions.

The decimeter signal does not have an extensive coverage area. Therefore, for its distribution, it is necessary to build a network of transmitters. The surrounding landscape, the presence of high-rise buildings, mountains, forests, the power of the repeater greatly affect the quality of the signal. Antenna installation must take into account all these factors.

Reception zone

A stable and reliable signal zone is an area within a radius of no more than 10 km from the television tower. Here, a simple indoor antenna will do a great job of receiving. If you have an amplifier, you can not use it.

If the signal disappears, the image breaks, then you need to connect the existing amplifier through the set-top box, using the appropriate menu item. Power will be supplied via the antenna cable.

Multi-story buildings can become a problem due to the reflection of decimeter waves. But the same reflection can be used. Let's say the antenna does not catch when it is oriented towards the TV tower. Point it at nearby tall buildings, the reception of the reflected signal will probably be much more effective.

It is necessary to check the presence of electrical appliances near the room antenna (third-party power supplies, etc.), as well as metal blinds on the windows. They can significantly weaken the signal.

Short circuit

There are times when the set-top box suddenly stopped responding to the use of the remote control, buttons, the image and sound disappear, and the screen displays “ Antenna short". The problem does not mean that digital television does not work. There is just a short circuit in antenna cable or in the receiver itself.

Why did the closure happen? There may be several reasons:

1. The presence of a short circuit in the cable associated with careless installation, in all likelihood, at the connection points. The antenna plug can only be damaged by manufacturing defects;
2. The active receiver is in operation, power is supplied to the amplifier. The amplifier is sensitive to lightning and can be damaged during bad weather;
3. Connected passive antenna, and the amplifier's power is turned on in the receiver's menu. Passive devices are often short-circuited.

IN last case you need to disconnect the receiver from the network, separate the antenna from it, then turn on the power again, on the connected tuner in the menu settings, turn the "Antenna Power" to the "Off" position.

Important! Finding and eliminating causes short circuit made after the attachment is separated from the mains.

Remote area from TV tower

Distance is considered to be more than 30 kilometers from the repeater. With a powerful transmitter and direct visibility, we install a small receiving device such as a wave channel or a log-periodic one. You need to direct the antenna to the TV tower. In such conditions, it is even possible to use an indoor unit with an amplifier.

With increasing distance and when a settlement is located in low places, the requirements for the antenna increase. More powerful samples are needed. A good receiving device necessarily includes an amplifier, and its arrow is long enough. There are samples with several arrows, but they will only be needed under extremely poor conditions.

Many users have a Polish antenna, since in the recent past it was popular because of its affordable cost. Its other name is the lattice. Can this design be adapted for digital television?

It is quite functional, but some changes are required. The antenna amplifier does not contribute, but interferes with signal reception. Therefore, it must be taken out of work. Simply disconnecting the power supply is often ineffective. More reliable - dismantle on the amplifier board tv cable and connect it in the same place to the two upper bolts: to one - the central core, to the other - the shielding braid. Thus, the amplifier is excluded from the circuit, and the antenna becomes passive.

Antenna and TV setup

There are several ways to properly set up a digital signal. The choice depends on the conditions of admission.

Auto search

This method is the easiest, but it requires a strong steady signal. The equipment is installed, turned on, digital channels are selected in the settings menu, and auto search is turned on. TV in automatic mode finds and saves the entire list of channels.

Manual mode

Suppose, in the auto-search mode, the TV cannot catch anything. Or found channels with interference. These pictures are not digital. Perhaps the TV went through the whole frequency range and caught a few analog channels.

Now it will be useful to know the numbers of TV channels (TVK), through which the signal is transmitted for each multiplex. Information about the location of the TV transmitter will also come in handy to direct the antenna in the right direction. If the house is surrounded by other residential buildings, you can navigate by neighboring receivers, but not by satellite dishes that "look" at their satellite.

1. The menu must be entered manual setting, after selecting DTV (digital television);
2. Enter the channel number or its frequency by typing from the remote control;
3. Two indicators will appear at the bottom of the menu, displaying the intensity television signal and its quality. Sometimes there is one indicator;
4. In the presence of even a slight signal, you can begin to turn and move the antenna in order to achieve its amplification. An instant reaction when changing the position of the receiving device is not worth waiting for. It will show up in a few seconds. The search should be carried out stepwise, with pauses. When the antenna is outdoor, it is difficult to do it alone, it is better to take an assistant;
5. Immediately after the appearance stable signal from good level you can start searching for channels and saving;
6. Channels of the second multiplex are tuned in the same way, if its reception is technically possible in the given area.

Important! If the signal disappears, then reappears with the scale filled to 100%, and this continues in turn, this means that there is no reception.

Complete lack of signal reception

This situation is typical for particularly unfavorable conditions, in low places, closed by mountains, next to high-rise buildings, with low-power towers located far away.

The search for a TV signal must be manual. At the same time, for its primary display on the indicators, you need to show patience and endurance, having tried different methods:

1. Purchase a powerful active antenna;
2. If there are other towers nearby, you can sometimes try manual search on a TV set to alternate repeaters. Perhaps the signal passing conditions will be better;
3. A good effect is to raise the antenna to a height using a mast;
4. When the TV tower is located close, and the house is located in the center of a densely built-up area with high-rise buildings, one should not rush to buy an expensive powerful receiving device. It is better to experiment with the reflected signal, alternately pointing the antenna at different sides on neighboring buildings or place it on the roof.

Tuning via receiver

Old TVs, models without built-in tuners with DVB support T2 require tuning through the receiver.

CRT TVs are connected to digital set-top box cinch cables (RCA), LCD models - HDMI cable. In the first case, the AV mode is selected during setup, in the second, HDMI. The mode is selected from the TV remote control. On the remotes, the choice of modes is located under different buttons: INPUT, SOURCE, VIDEO, just a rectangle with an arrow.

Subsequent setting is carried out using auto-search or manually using the set-top box. The antenna must be connected to the set-top box.

Receiving a digital television signal on a conventional antenna is an easy way to provide yourself with a high-quality picture, requiring minimal financial costs and physical effort. With the development of the network of TV towers, the signal reception conditions will improve.
