The state program for a phased transition to the digital broadcasting standard DVB T2 is approaching the final stage - a gradual reduction in the number of analog repeaters. This suggests that the time has come to get involved in new technologies and switch to the "digital". We will talk about the equipment necessary for receiving a television signal in a new format, as well as how to properly connect a digital set-top box (receiver) to a TV or monitor.

Necessary equipment

To watch digital broadcasting, unlike analog broadcasting, you need a receiver that decodes the signal. Many modern TV models (Philips, Samsung, Sony, Toshiba, LG, Panasonic, etc.) are equipped with such a unit. To verify this, refer to the user manual, this brief instruction is attached to each product. At the same time, check whether the built-in tuner supports the DVB-T2 format, if not, you will need to purchase a receiver.

Depending on the set of functional capabilities, the cost of such a device can vary between 800 - 3000 rubles. Note that many providers of digital cable television provide subscribers with receivers for rent.

In addition, we will need to receive a digital signal. In cities and large settlements with this problem will not arise, it is enough to contact local providers. Residents of rural areas will need to install a decimeter band antenna or satellite dish. The latter is preferable, since it is not a fact, your house is in the coverage area of \u200b\u200bthe nearest digital repeater. In addition, the satellite dish option provides a wider selection of television channels.

Consider what is included in the standard kit for the receiver, this information may be useful when it is connected to a television receiver.

We list what is shown in the figure:

• A - user manual, we recommend that you carefully read this manual to get a complete picture of all the functionality of the device and its connection to the TV and antenna.
• B - Tulip cable (RCA) with characteristic connectors, allows you to connect the console to almost all modern models of television receivers.
• C is a device for decrypting and converting a digital signal into an analog (receiver).
• D - packing box.
• E - remote control for remote control of the device.
• F - batteries for the remote control.
• G - network adapter for connecting the device to a household electrical outlet.
• H - warranty service coupon.

The basic equipment may slightly differ from that shown in the photo (for example, “Tulip” is replaced by an HDMI cable).

Connectors and their purpose

On the back of the device there are various connectors, briefly tell you what they are for.

Explanation of the figure:

1. Antenna Output
2. A connector for connecting a satellite dish, a decimeter antenna, or a local provider's cable.
3. A jack for an HDMI cable allows you to connect a monitor or TV equipped with this input (digital output can transmit sound and image).
4. Sockets for the Tulip cable (transmits an analog video signal, as well as stereo sound).

Some devices can be additionally equipped with a SCART connector, a TV, VCR or DVD player with video recording function is connected to it.

In addition, there may be devices where instead of the HDMI jack, D-SUB (Fig. 5) or DVI outputs are installed.

Please note that such interfaces do not transmit sound, so an additional connection with the help of "tulips" will be required to transmit it.

The process of connecting a digital set-top box to a new TV is step by step

Important! All manipulations must be done with the equipment turned off. If you connect working equipment, there is a high probability of its failure.

We will describe the order of our actions:

1. You must select the interface for connecting the console to the TV. It can be analog (tulips, D-SUB, SCART) or digital (HDMI, DVI). The choice is made depending on the specific TV model. Despite the fact that many FULL HD class television receivers have an analog input, it is better to feed them a “digit”, since double signal conversion will negatively affect the quality of the “picture”.

This interface allows you to transmit video and sound, so the connection can be made with a single cable.

If the TV does not have a digital input, it is connected by any analog interface, the easiest way to do this is with tulips. In the case when the device has only a bulky SCART connector, you can purchase an adapter for the tulip for it. In this way, you can connect almost any model, except for very ancient ones.

1. We check the availability of the cable necessary for connecting, it can go bundled with the receiver or television receiver. If you could not find one, you will need to purchase it.
2. We remove the protective film from the set-top box (if any), install it in the chosen place and connect it to the TV. The cables are made in such a way that it is physically impossible to insert them into the connector not intended for this purpose. The exception is tulips, they can be confused. But, to prevent this, manufacturers make nests for them in the corresponding color.

As you can see, the colors of the connectors coincide with the colors of the sockets (4 in Fig. 3).

1. We connect power to the console. If the power adapter is built-in, we simply plug the plug into a power outlet, and we pre-connect the external power supply to the corresponding socket on the receiver.
2. We connect the provider's cable, decimeter antenna or satellite dish to the antenna input (2 Fig. 3).
3. We insert the batteries into the remote control, turn on the console and the TV.

This completes the connection procedure, and you can begin to configure the channels. If your TV does not have the above interfaces, do not worry, we will tell you how to get out of this situation.

Connect to an old TV

The signal converter can work even with old models of television receivers when connecting them to the antenna output (1 in Fig. 3). To do this, you need a piece of antenna wire of the appropriate length and two antenna plugs. In order not to trouble yourself with soldering, you can take special F-connectors, the procedure for mounting them on a cable is shown in Figure 8.

Procedure:

1. Remove the insulation from the antenna cable, carefully so as not to damage the braid (just clean 15 mm).
2. We bend the braid, as shown in the picture.
3. Carefully remove the insulation from the central core.
4. It is necessary to expose 10 mm of the central wire.
5. Screw the connector clockwise.
6. We do this until the central core protrudes 2 mm from the connector.

Using the cable made, we connect the antenna input of the TV to the corresponding output of the console. In this way, you can connect any TV, whether it be Horizon 101 or the legendary KVN.

How to connect 2 TVs to a digital set-top box

Two television receivers can be connected via the antenna output, for this you need a special adapter with one to two cables (splitter).

Since the set-top box is intended for only one device, two televisions will work simultaneously, that is, show the same channel.

Customization

The set-top box is configured in the same way as a TV, namely:

• The menu is called up using the button of the same name on the remote control.
• Select the appropriate command that starts the channel scan.
• When the scan is finished, we save the list of detected channels, if desired, they can be grouped in a certain way, give a name, etc.

Detailed instructions and a description of the functionality can be found in the user manual. In most cases, the menu interface is intuitive, so setting up the receiver is as simple as connecting a digital set-top box to the TV.

The modern world is impossible to imagine without digital TV. Such signal transmission has long been used for broadcasting television and radio channels in many countries of Europe, America and Asia. In Russia, the process of transition from analogue to digital TV was delayed.

The digital signal coming through the receiver’s antenna allows you to watch more TV channels across the country without loss of quality and interference. The signal itself can then come both to the antenna, which is attached to the set-top box, and directly to the TV. It all depends on how modern the model of this device you have.

With devices that support DVB-T2, everything is simple. In order to connect to a digital TV, just insert the cable into the appropriate connector and perform a simple one. If your TV is outdated and does not support reception of this type of signal, then in order to view it you should purchase a special set-top box. It is inexpensive, but some people may have problems connecting it and setting it up, so today we’ll talk about how to do it.

What is needed for this

To connect a digital TV you will need:

• TV set;
• Prefix (receiver);
• Antenna.

At the same time, your TV should have an input into which you can insert an antenna, a tulip-type connector, as well as an input with a video output (scart). If together you have a scart connector hdmi input, then do not worry. It is also suitable for connecting the receiver. Just your model is newer.

Before buying a receiver, you should understand which one is better and find out which parameters you should pay attention to in order to choose the most optimal model. If you don’t understand much about technology and don’t want to spend your free time studying all these nuances, you can contact a company that provides broadcasting services in your city and get advice from their specialists. In addition, you can take advantage of promotional offers from a service provider. Often, provided you connect to their services, you can receive the receiver as a gift.

The receiver, in fact, is an adapter that allows you to receive and transmit a signal to your device. He can receive it through the following sources:

• Satellite dish;
• Antenna
• Through the Internet;
• Using other sources.

Connecting a digital set-top box

In order to connect the receiver directly, you should do the following:

1. Take the TV box out of the box and remove the protective film from it. Film must be removed. Otherwise, the receiver may overheat and break.
2. Take a TV cable and cut off the protective sheath, thus exposing 1-15 millimeters of cable on both sides. The shell should be cleaned very carefully so as not to damage the shielding film, which is designed to protect the center conductor.
3. Gently peel back the shiny protective film and screw the f-connectors to the wires.
4. Connect the TV to the set-top box with a cable.
5. Insert the wires into the tulip connectors on the TV and set-top box.
6.   . In this case, the antenna itself should be installed on the external wall of the house or on your balcony if it is not glazed. At the same time, make sure that it is not touched by tree branches or power wires.

This completes the process of connecting a TV set-top box. Next, to watch the available channels in your area, you must configure it.

In our country, many people still use televisions, which were produced back in the Soviet years or in the early 90s. Connecting a receiver to such devices is not so easy - they do not have “tulip” connectors. In addition, some models have scart outputs, but they only accept component signals.

There are two ways to solve these problems:

• Find the circuit for the adapter from the input A / V to scart and solder it yourself;
• Buy a special adapter in the store, to which you can connect the RCA cable from the console or the adapter cable.

There are even more ancient models of televisions of the type "Electron" in which no inputs are provided at all, except for the antenna connector. Through this connector, a modulated high-frequency signal is supplied to the TV, so in order to watch digital TV on this type of device you will need to purchase an additional modulator that will be equipped with RCA connectors.

Receiver Setup

In order to configure digital channels on the TV, after connecting to the set-top box, you will need to perform the following steps:

1. On the remote control, press the "Menu" button.
2. In the window that opens, go to the settings menu.
3. As a country you need to choose Russia, if it is not by default.
4. Now you need to select a signal standard. By default, DTV-T / DTV-T2 is set, that is, analog and digital TV, respectively. If you leave it like this, the TV will search for both these and these channels.
5. You will be prompted to perform automatic or manual tuning. Select Automatic and press the OK button on the remote control.
6. Now you need to wait a while until all available free and paid TV channels are discovered. At the end of the search, click "Save."

This is one of the easiest ways to set up digital TV at home. If the TV found few channels or did not find them at all, then you should use manual tuning.

To do this, you need to delete all the channels that were found for this. After the channels are deleted, you must repeat the same steps as for automatic search, but instead of automatic tuning, select manual search. You will see a window in which you should set the frequency at which digital channels are broadcast in your city. You can find out this frequency online or by contacting your service provider. It may also be necessary to change the search range in order for the search to begin.

After the TV channels of the first multiplex are found, you will need to find out the frequency for the second multiplex in your city and start the manual search again. Thanks to this, you can watch more channels.

Signal Quality Check

To make sure that you did everything correctly and everything works well, you should check the signal reception quality. Make it easy. There should be a button on the receiver with the name INFO. By clicking on it three times, a window appears with information on signal quality, channel number, frequency and encoding. If the two existing indicators are above 60%, then everything is fine and the signal level is quite acceptable.

Perhaps, in your model of TV set-top box, this button will be called differently. To find out how this button is called with you, look at the instructions and read the purpose of the buttons.

If your TV catches several multiplexes, do not forget to check the signal quality on each of them. This is due to the fact that each of them is transmitted and received using different transmitters, so it is very possible that in one multiplex the signal will be good, and in the second - not.

TV), it's time to go to the most important part - setting up digital tv. How to set up digital TV do-it-yourself? Read about it later.

I will show on the example of the receiver Mystery MMP-71DT2, and like me, his software completely coincides with Rolson. If you have a different prefix, the principle will be the same, but you may have to look into the instructions.

How to connect everything

To start, we connect the antenna to the receiver, and the receiver to the TV. Preferably through, so the image quality will be as clear as possible. If not, then through the usual "tulips", they come complete with a prefix, as a rule. We look at the connectors in the instructions, it will turn out something like that. If the antenna is with an amplifier, first turn it off, then you can always turn it on.

We start all this economy, the prefix, the antenna, the TV. Select the desired video input. If everything is done correctly, then you will see the start menu, like this:

How to set up digital television through "auto search"

By default, the prefix is \u200b\u200bnot configured for anything, and you yourself will need to catch the channels that are transmitted in your area. The easiest way is to start auto search.

After launching the auto search, the prefix will think for a long time, and should find something in the end. Important: since each is transmitted on the same frequency, you will not catch channels one at a time, but immediately in packs of ten. So be patient. If the channels are caught one at a time in an analog TV, then several minutes may pass and the set-top box will search. But then all 10-20 channels will jump out immediately.

After the search is over, the prefix will offer you to add the found channels. If you find all 20 pieces - congratulations, the process is complete!

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 is very easy to do. You should have an INFO button on the set-top box, a triple press displays data on signal quality and intensity. Look in the instructions, it may be called differently, but it will do the same:

The higher the signal, the better. Optimal - from 60% onwards

If both indicators are high, above 60%, all is well.

Check on both multiplexes, say, on Channel One and on TNT.

Since different multiplexes are transmitted, you can catch the first well and the second bad, or vice versa. Your task is to twist 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 caught doubles or nothing was caught

The second option is when not everything is caught, or nothing is caught. Here, fine tuning and manual mode will help us. We read about it. However, if you live in a city and there are towers near you, then in 90% of cases auto search is enough for you.

Summarizing

As you can see, setting up a dvb t2 digital television with your own hands is not any complicated matter. And certainly you should not call a master who will do the same for a thousand rubles)

A channel package broadcast on a single frequency is called multiplex. The number of channels in one multiplex can be from 1 to 10. The composition and number of channels is determined by the broadcaster, for example, the state.

There are 3 multiplexes working in Crimea so that they do not interfere with each other, as in analog broadcasting, in each region broadcasting is carried out at different frequencies (CHANNELS).

DVB-T2 broadcasting in Russia, Ukraine and a number of other countries is carried out only in the decimeter frequency range - these are from 21 to 69 UHF channels.

List of transmitters and frequency channels broadcasting in Crimea

Alupka - 21, 30, 43 (Lenin St. 64)

Alushta - 30, 32, 56 (13 Sergeeva-Tsensky St.)

Annovka (Belogorsky district) - 22, 32, 41

Belogorsk - 36, 37, 58 (33a Nizhnegorskaya St.)

Yalta - 26, 35, 37 (South Coast Highway 55)

To receive DVB-T2, you need (preferably) an external decimeter television antenna without an amplifier with a modern cable with minimal signal attenuation in it. Use of all-wave antennas is possible. More often, an antenna with a good cable receives a signal better than an antenna with an amplifier and an old cable. The use of the Soviet cable RK-75 is not allowed, such a cable was not designed to receive signals in the UHF range, therefore, it has large signal attenuation.

It also happens that in the same village, for example, Nikolaevka, Zuya, depending on the place of reception, reception can be carried out from different directions. So, on one side of the Zuya lowland, the signal can only be received from Simferopol, and on the other side of the settlement only from Belogorsk.

If reception is carried out outside the line of sight of the direction to the transmitter, then the maximum signal is possible even in the opposite direction from the transmitter. In this case, a reflected signal is received. To determine the ideal orientation of the receiving antenna, select the manual channel search mode on the TV or set-top box, then enter one of the channels (preferably with a lower number from the list above) from the transmitter from which you want to receive the signal. Now you can see the scale of the level of the received signal and orient the antenna along it.
Turn the antenna 5-10 ° in any direction, count to 10 in your mind, write down the signal level. Turn the antenna 5-10 ° in the same direction
(further) and again count to 10 and record the level of the received signal. Thus, rotate the antenna a full revolution around its axis 360 °.
After that, you will see from your notes which direction the maximum signal is coming from.

With the advent of the digital terrestrial television era, many cable and satellite network subscribers are increasingly thinking about connecting free broadcasting. Indeed, according to the Federal Target Program, the development of a digital broadcasting network will appear in the public domain 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 nothing complicated. To receive digital terrestrial television, you will need any standard subscriber equipment DVB-T2 / MPEG-4   with mode support Multiple PLP   and decimeter antenna ( Dmv) range. The antenna can be either collective (installed on the house, also called common house) or individual, installed directly in your house or apartment. Depending on the distance to the transmitting center, you need to select the desired antenna. They are divided into active (with amplifier) \u200b\u200band passive. When buying an antenna, you can first clarify the power of the transmitting equipment installed in your region and the distance to the transmitting center. Based on the data obtained, pick up the 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.

We proceed directly to the equipment for reception. Three main groups can be distinguished: televisions with a built-in tuner DVB-T2, set-top boxes of the same standard and digital computer tuners DVB-T2. Their setup is similar, if not the same.

Video: how to set up DVB-T2 digital terrestrial television

It’s best to connect a digital terrestrial set-top box according to the manufacturer’s instructions; there’s practically no mistake there. You can also watch the official video from RTRS:

A few recommendations, also from RTRS:
   connect the plug of the antenna cable and, if necessary, the digital set-top box to the TV;
   connect the auto search of channels - the TV will tune to the corresponding digital air channel, when tuning to the channel in manual mode, you must specify the channel frequency (for example, 35 TV channel, 685 MHz);
   most digital TVs (and set-top boxes) have a built-in indicator of signal level and quality, which will allow you to optimally configure your antenna to receive digital broadcast signals (see the operating instructions for the TV).

In televisions with a built-in tuner DVB-T2, all manipulations are carried out through the TV's menu. There should not be any difficulties there either.

We recommend updating the software of your subscriber equipment to the most current one. This can be done in specialized services, or by yourself (if you are confident in your abilities). Software can usually be downloaded from the manufacturer’s official websites.

When a new level of data transmission quality appeared, the digital television network DVB-T2 was launched. Digital television provides high picture quality and excellent transmission signal. But in order to configure a connection to this network, you need to have the necessary knowledge, choose the right receiver and configure it well.

How to connect a T2 module and configure it will be described below.

How to connect the T2 prefix to the TV

The T2 tuner is easy to connect to the TV. If you had the experience of connecting players, antennas and other devices to the TV, then it will not be difficult to connect the receiver.

We connect the antenna to the receiver, and from it we connect the wires to the TV. This can be done using standard HDMI wires, tulips or SCART. Most importantly, you won’t have to pay for calling the wizard. However, if the master can connect the set-top box to the TV for free, then it is worth giving the case to him.

How to connect DVB-T2 to a TV without a set-top box

To connect the TV directly to the DVB-T2 network without buying a receiver, you can immediately purchase a TV with a built-in DVB-T2 tuner. This saves space, time and cost. Among other things, it will be possible to control T2 channels with one remote control from the TV, while there will be two remote controls with the receiver.

Today, almost all LCD TVs have a built-in tuner, which makes connecting easier. Simply insert the antenna into the desired socket.

How to set up DVB-T2 using the receiver

After installing and connecting the receiver, you must configure the television. To do this, we perform simple steps:

• We go to the prefix menu.
• Click "Quick Setup".
• If the default is another country, then install "Russia".
• Then you must select the standard “DVB T2”. It often stands in the field of the DVB T / DVB T2 standard, which leads to the fact that the receiver is looking for DVB T quality channels, and only then DVB T2. We need DVB T2 and its excellent quality.
• Then we press "Auto tuning" and everything will be done automatically.
• After finding the channels, you can also see detailed information on the quality of communication by clicking the "Info" button.

Thus, you can configure the receiver to receive all the necessary channels. But not always tuning goes smoothly. Sometimes, problems arise.

What to do if DVB T2 setup does not occur

There are several options why the configuration does not occur:

• The problem is in the receiver;
• The problem is in the antenna;
• The problem is in the TV.

To get started, try tuning with a different antenna. If it helped, then the problem is in the antenna, and if not, then the receiver is to blame.

If the antenna is to blame, then only a specialist will help. If the receiver, then several options are possible. Firstly, the receiver may have the wrong firmware. Then you need to reflash the prefix. To do this, go to the manufacturer’s website, download the new firmware, write to the USB flash drive and insert it into the receiver. It will update itself and the problem will be fixed.

If updating the firmware does not help, then the point is most likely in electronics. In this case, it is better to hand over the prefix to the service or change it under warranty.

You can also check the TV itself. To do this, use the set-top box on another TV, and if it works, then it may be in the TV settings. In this case, you should contact the manufacturer. There they will be able to tell you how to correctly set the TV settings for connecting the receiver.

How to choose a prefix for DVB-T2

The choice among the receivers is quite large. Here are the most popular receivers recommended to buy:

• Trimax TR-2012HD
• Strong SRT-8500
• Strong SRT-8502
• Thomson tht702
• Trimax TR-2012HD PVR (TR-2013HD PVR)

Their price starts from 1000 rubles and higher depending on the functions. More expensive receivers have more subtle settings, a better reception signal, more different inputs for connecting additional devices, and they also work faster. Compared to satellite set-top boxes, the DVB-T2 receiver is inexpensive.

You can also go to any hardware store and there, on the spot, choose a new receiver, after consulting with a specialist.

The introduction of the DVB-T2 standard digital terrestrial television in Ukraine has significantly expanded the areas of reliable reception of TV tower signals, in comparison with the analog signal. Also, the simplicity in setting up and installing T2 did the trick, they became much more popular than satellite television with MFA channels.

Let's move on to the practical side and talk about the direct installation of all the equipment necessary for receiving DVB-T2. Many modern televisions are already equipped with an integrated DVB-T2 receiver, in this case it is enough to find out the position of the repeater, point the antenna at it and scan available channels using the TV. In the case of a simple TV, the installation and connection of T2 is somewhat different, we will now discuss it. To install T2 in the standard version you will need:

1. DVB-T2 digital receiver , the necessary form factor, for example, for a hidden installation with a remote IR sensor and so on. The choice is huge now, there is practically no significant difference, everyone can choose for their needs. Practice shows that it is worth buying in a reliable store with a guarantee, we suggest you buy a receiver from our partners who will provide you with service, warranty and repair.

1. UHF Antenna , in practice, the so-called “Polish antennas” are often used, you can also purchase an antenna manufactured by Konvalia, Margoon, etc., you just need to take into account that the antenna must be taken with a gain margin, since it is predicted how the signal will be received in a particular case hard to say. It is also desirable that it has an amplification board that can receive power both from and from an external power supply.
2. Cable, ordinary television , almost any one will do, but it’s better to take it with a braid filling percentage of 50% or more.
3. RCA or HDMI cord for connecting the receiver to a TV may be included or must be purchased separately.

Digital T2 connection using the World-Vision T38 receiver as an example

First you need to install the antenna, if it has not been installed before. It’s probably stupid to advise here, I’ll just say that follow the manufacturer’s recommendations, and at least turn it in the necessary direction. In which direction to direct the antenna, you can find out by looking at neighboring antennas or calculate the direction, for example, using Google or Yandex maps.

Connecting a T2 digital receiver to the antenna will also not cause much difficulty, the manufacturer and standardization makes this process simple and it is quite difficult to make a mistake here.

When connecting it is difficult to confuse something, the RCA cable is simply connected, just follow the color on the plug and on the socket, yellow to yellow, white to white, red to red. The antenna connector will also not allow you to connect other plugs to it, in this model of the receiver it is located on the left edge. It is also possible to connect via HDMI, everything is simple here, the COAX connector is used to connect a digital audio signal amplifier and is practically not used in standard configurations.

After all the cords are in place, we connect the last one - the connector of the power supply unit, in this model it is on the side panel.

On this, the connection of the T2 receiver is almost complete. Next, turn on the TV and receiver. By pressing the “AV-TV” toggle button on the TV remote control, we switch from the antenna jack to “tulips”, in newer TVs we select the input to which the receiver is connected. The following should appear on the screen:

The receiver will restart and a menu will appear with a search for channels and setting the initial parameters of the receiver:

We select the parameters and click "Auto Search", the receiver will scan and display the channels found.

If not all the channels were found or they are not at all, adjust the antenna and repeat the search from the receiver menu until the number of channels and the reception quality satisfy you. Enjoy watching!

After the advent of digital television, many users wanted to switch to its reception. It is not only a matter of frequent discussions and the desire to try a new product. Signal quality is an order of magnitude higher, and ease of access increases attractiveness. It is possible to connect digital TV to obsolete kinescope models using additional devices, and to modern TVs.

Digital reception methods

There are several ways to connect a high-quality signal to a TV:

1. Cable TV. Reception is carried out via a common cable. The disadvantage is the monthly fee and not widespread availability;
2. Satellite television. The signal is transmitted via satellites, and reception - using an individual dish. A monthly fee plus the purchase of special equipment is also required;
3. Broadcast TV. The digital TV signal is distributed from terrestrial repeaters; it can be received from an antenna, indoor or outdoor. This is a completely free method of watching TV in a modern format. It has drawbacks: often a low signal level, weather, the location of the tower, etc. can affect the image quality.

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

How does digital television work?

The transmission of picture and sound for digital television is accomplished by encoding the video signal and sound over digital channels. Digital coding differs from analog in immunity to interference (external obstacles). 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 small squares, from time to time disappear and reappear. It depends on how to set up the antenna. Alternatively, you can install another antenna or raise and deploy an existing one, pointing to the TV tower.

Necessary equipment for viewing

1. Antenna;
2. A separate set-top box with a DVB T2 tuner that supports MPEG 4 and can operate in Multiple PLP mode.

You can use the antenna with the usual analog. If the TV was released relatively recently, then it may have a built-in tuner of the required format (the outdated DVB T format is no longer supported). Then nothing more needs to be acquired.

To find out if there is a built-in tuner DVB T2, you can see the data in the data sheet. It’s even easier to find a TV model on the Internet and get an exhaustive answer.

Choosing a Digital Tuner

At first glance, all set-top boxes are the same. The main thing is not to make a mistake in the main technical characteristics. But there are other features that affect the further operation of the equipment and the breadth of the functions covered:

1. The lack of buttons on the external panel of the console will oblige you to use it only with 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. Usually it is built in. The most common cause of a tuner failure is a power supply failure. If it breaks down, you need to repair or replace the entire console, and the remote power supply must be replaced separately without problems.

Many hang the TV on the wall, and high enough. Then use the usual design of the console is inconvenient. There are modifications of the equipment - compact consoles, which are attached to the back of the TV with tape. The strength of the attachment must be considered. Such a receiver is controlled by the remote control through a separate sensor mounted on the same tape on the external panel of the TV. Power is supplied by wire from the TV's USB port.

The prefix can also be used in conjunction with a computer monitor (if there is an HDMI port). Then you can watch digital television from a conventional antenna. If the built-in television tuner fails, it is easy to replace it with the receiver.

What channels are available for viewing

To watch free digital channels through a regular 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. In other regions, they may vary. In total, twenty television channels and 3 more radio programs are available.

Important!   The TV does not catch additional channels. Tuning the antenna will not affect the number of received channels, but only on their quality.

How to locate a TV tower

Users living in the city, in the reception area of \u200b\u200bthe signal 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 necessary for a better choice and proper tuning of the antenna:

1. The exact place where the tower is located and the distance to it;
2. Technical parameters (channels and broadcast frequencies), using which you can catch a digital signal in a given area. This is necessary in order for the user to configure the TV channels on the console in manual mode;
3. Is the entire list of channels available for reception? There may be one or two packages.

Full information on TV towers is on the official website of RTRS. There are maps where you need to enter the name of a specific settlement in the search line. A map of the area will immediately open, on which all the 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 installed working transmitters, channel numbers (TCEs), broadcast frequency, number of packets).

The active menu includes a function, by using which you can find out the coverage areas of individual repeaters.

Now, armed with knowledge, it is necessary to determine whether it is enough to install a room antenna or if a street, more powerful one is required.

Antenna Types

An analog signal is received at the MV antenna. DVB antennas are more compact. There are combined samples that can take both ranges. Unnecessary elements can be removed from such a combined design, and an excellent UHF antenna will be obtained. For example, if a long mustache is present (an element for an MV signal), they can be removed.

All antennas are divided into:

• active;
• passive.

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

An amplifier does not always mean better reception, in some cases its use will even harm:

1. In the area near the TV tower, turning on the amplifier may lead to complete loss of reception due to too strong a signal;
2. An amplifier is the weakest element of an antenna, often failing. Plus a power supply and additional wires that also require repair and replacement;
3. The intensity of the television signal itself is provided by the design of the antenna. And the amplifier simultaneously 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.

Selection and installation of the antenna

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

The decimetric signal does not have a wide 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, and repeater power strongly affect the signal quality. Antenna installation should be carried out taking into account all these factors.

Reception Area

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

If the signal disappears, the image breaks, then you must connect the existing amplifier through the console, using the appropriate menu item. The power will come over the antenna cable.

Multi-storey buildings may become a problem due to the reflection of decimeter waves. But the same reflection can be used. Suppose the antenna does not catch when it is oriented to the TV tower. Direct it to neighboring tall buildings, the reception of the reflected signal may be much more effective.

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

Short circuit

There are times when the console suddenly stops responding to the use of the remote control, buttons, the image and sound disappear, and “Antenna short” is displayed on the screen. The problem does not mean that digital television does not work. There is simply a short circuit in the antenna cable or in the receiving device itself.

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

1. The presence of a short circuit in the cable associated with sloppy installation, in all likelihood, at the connection points. The antenna plug can only be damaged during manufacturing defects;
2. In operation, an active receiving device, power is supplied to the amplifier. The amplifier is sensitive to lightning discharges and may be damaged during bad weather;
3. A passive antenna is connected, and amplifier power is turned on in the receiver menu. Passive devices are often short-circuited.

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

Important!   Search and elimination of the causes of a short circuit is performed after separating the console from the mains.

Remote area from the TV tower

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

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

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

It is fully functional, but a number of 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 inefficient. More reliable, on the amplifier board, dismantle the television cable and connect it there to the two upper bolts: to one - the central core, to the other - a shielding braid. Thus, the amplifier is excluded from the circuit, and the antenna turns into a passive one.

Antenna and TV settings

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

Auto search

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

Manual mode

For example, in auto search mode, the TV can’t catch anything. Or channels with interference are found. Such pictures are not digital. Perhaps the TV at the same time went through the entire frequency range and caught several analog channels.

Now useful is the knowledge of the numbers of television channels (TCEs), through which a signal is transmitted for each multiplex. Useful information about the location of the repeater to direct the antenna in the right direction. If the house is surrounded by other residential buildings, you can navigate by neighboring receiving devices, but not by satellite dishes that “look” at their satellite.

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

Important!   If the signal has disappeared, then it appears again with a full scale of 100%, and so it continues in turn, this means no reception.

Complete lack of signal reception

This situation is characteristic of particularly adverse conditions, in low places, closed by mountains, next to high-rise buildings, with far-reaching low-power towers.

Search for a television signal must be manual. At the same time, for its initial display on indicators, patience and endurance must be shown, having tried different methods:

1. Buy a powerful active antenna;
2. If other towers are nearby, you can sometimes try manual search on a TV set up for alternative repeaters. Perhaps the conditions for the passage of the signal will be better;
3. A good effect is given by raising the antenna to a height using the mast;
4. When the TV tower is located close, and the house is located in the center of a densely built-up area of \u200b\u200bhigh-rise buildings, one should not rush to buy an expensive powerful receiver. It is better to experiment with the reflected signal, alternately directing the antenna in different directions to neighboring buildings or position it on the roof.

Setup via receiver

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

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

Subsequent adjustment is performed using auto search or manual using a console. The antenna must be connected to the console.

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

Video

When a new level of data transmission quality appeared, the digital television network DVB-T2 was launched. Digital television provides high picture quality and excellent transmission signal. But in order to configure a connection to this network, you need to have the necessary knowledge, choose the right receiver and configure it well.

How to connect a T2 module and configure it will be described below.

How to connect the T2 prefix to the TV

The T2 tuner is easy to connect to the TV. If you had the experience of connecting players, antennas and other devices to the TV, then it will not be difficult to connect the receiver.

We connect the antenna to the receiver, and from it we connect the wires to the TV. This can be done using standard HDMI wires, tulips or SCART. Most importantly, you won’t have to pay for calling the wizard. However, if the master can connect the set-top box to the TV for free, then it is worth giving the case to him.

How to connect DVB-T2 to a TV without a set-top box

To connect the TV directly to the DVB-T2 network without buying a receiver, you can immediately purchase a TV with a built-in DVB-T2 tuner. This saves space, time and cost. Among other things, it will be possible to control T2 channels with one remote control from the TV, while there will be two remote controls with the receiver.

Today, almost all LCD TVs have a built-in tuner, which makes connecting easier. Simply insert the antenna into the desired socket.

How to set up DVB-T2 using the receiver

After installing and connecting the receiver, you must configure the television. To do this, we perform simple steps:

• We go to the prefix menu.
• Click "Quick Setup".
• If the default is another country, then install "Russia".
• Then you must select the standard “DVB T2”. It often stands in the field of the DVB T / DVB T2 standard, which leads to the fact that the receiver is looking for DVB T quality channels, and only then DVB T2. We need DVB T2 and its excellent quality.
• Then we press "Auto tuning" and everything will be done automatically.
• After finding the channels, you can also see detailed information on the quality of communication by clicking the "Info" button.

Thus, you can configure the receiver to receive all the necessary channels. But not always tuning goes smoothly. Sometimes, problems arise.

What to do if DVB T2 setup does not occur

There are several options why the configuration does not occur:

• The problem is in the receiver;
• The problem is in the antenna;
• The problem is in the TV.

To get started, try tuning with a different antenna. If it helped, then the problem is in the antenna, and if not, then the receiver is to blame.

If the antenna is to blame, then only a specialist will help. If the receiver, then several options are possible. Firstly, the receiver may have the wrong firmware. Then you need to reflash the prefix. To do this, go to the manufacturer’s website, download the new firmware, write to the USB flash drive and insert it into the receiver. It will update itself and the problem will be fixed.

If updating the firmware does not help, then the point is most likely in electronics. In this case, it is better to hand over the prefix to the service or change it under warranty.

You can also check the TV itself. To do this, use the set-top box on another TV, and if it works, then it may be in the TV settings. In this case, you should contact the manufacturer. There they will be able to tell you how to correctly set the TV settings for connecting the receiver.

How to choose a prefix for DVB-T2

The choice among the receivers is quite large. Here are the most popular receivers recommended to buy:

• Trimax TR-2012HD
• Strong SRT-8500
• Strong SRT-8502
• Thomson tht702
• Trimax TR-2012HD PVR (TR-2013HD PVR)

Their price starts from 1000 rubles and higher depending on the functions. More expensive receivers have more subtle settings, a better reception signal, more different inputs for connecting additional devices, and they also work faster. Compared to satellite set-top boxes, the DVB-T2 receiver is inexpensive.

You can also go to any hardware store and there, on the spot, choose a new receiver, after consulting with a specialist.
