The TV needs to show digital channels. Digital terrestrial television, how to set up an antenna under different signal conditions
Features of CETV
Digital terrestrial television (DTTV) makes it possible to receive Federal TV channels and radio stations included in the first and second multiplex in the MPEG-4 standard. Below you can find a list of these channels.
The peculiarity of this type of television broadcasting is that you can watch the listed television channels in high quality. As you know, the previous generation of broadcasting - analogue terrestrial TV, is already outdated, since the broadcast picture has a low resolution, and on modern wide-screen TVs the image is of very low quality and blurry. The new format of television broadcasting opens up new dimensions, giving subscribers a high-quality, clear picture and high-quality stereo sound.
CETV broadcasting is carried out in principle, like regular broadcasting of UHF channels, only one channel includes 10 digital ones. There are only 2 such channels, they represent the first and second multiplex. To process the signal, you need a special digital terrestrial receiver - set-top box.
Equipment
Let's take a closer look at the set of equipment that is needed to receive digital terrestrial TV channels high definition.Necessary equipment:
- Antenna;
- Receiver (tuner);
- Amplifier;
- Coaxial cable;
- Cable for connecting the receiver to the TV.
To receive the CETV signal, you need a conventional decimeter antenna that receives channels in the frequencies 470–860 MHz. Antennas can be of two types: home (indoor) or external. The type of antenna must be selected in relation to the distance from the TV tower (repeater).
A home antenna is only suitable in cases where there is a TV tower in your city, at a distance of no more than 15 km from your home. In this case, you can get by with an indoor antenna. If your distance to the TV tower exceeds 15 km, then you must use an external antenna.
In the shop household appliances or radio electronics, decimeter antennas for DVB-T2 will definitely be available. Buy special antennas that are designed to receive UHF signal, they are designed according to all the rules of radio physics and will provide high-quality signal reception.
Talk to your neighbors, probably some of them watch CETV, find out what antenna they use and what the level and quality of the signal is.
If in doubt, buy an external antenna.
Receiver (tuner)
The first thing you need to do is choose a receiver. A receiver is a special set-top box for a TV., as mentioned earlier, which processes the signal and sends it to, setting up channels and switching them is also done through the receiver. Today there are enough on the market wide choose receivers for receiving DVB-T2 channels.
As for the choice, they are all almost identical and simple; choose a device based on availability additional functions: functionality and design of the menu, as well as the availability of connectors for connecting to a TV.
In some modern TVs, from the middle and premium segments, there are models with a built-in DVB-T2 tuner, thanks to which you do not need to buy a receiver, but simply connect the cable from the antenna to the appropriate socket and configure the channels.
If you have, then some models support installation CAM modules, including the DVB-T2 module. Thus, you only need to install the module in the receiver, connect the cable from the antenna to the second incoming socket, and you can watch digital terrestrial television channels along with satellite ones.
Amplifier
Most UHF antennas (both indoor and outdoor) include a built-in amplifier, the signal from which is amplified by the receiver, which is quite enough for confident reception, if the antenna type is selected correctly.
Let's consider cases when a separate signal amplifier is needed. Using a DVB-T2 receiver, you can check the signal level; to do this, you need to enter the settings and the corresponding scale will be displayed there. Connect the antenna to the receiver - if the signal level is around 75% and the picture quality is quite satisfactory, then an amplifier is not needed. When the signal level is lower and the picture is noisy, it is recommended to install an amplifier.
Coaxial cable
This is normal tv cable, which transmits the signal from the antenna to the receiver. We recommend purchasing a cable with a copper circuit and screen, as it is of the highest quality, which will ensure good transmission signal and long term cable operation. Pay attention to the cable braid; the stronger it is, the better, since the cable will be less susceptible to external influences: interference and destruction.
Cable for connecting the receiver to the TV
If the receiver you select includes HDMI connector, which is also available on the TV, it is better to use it for connection, since this type connection provides the best image quality. For this you will need HDMI cable, which can be purchased at any hardware or computer store.
If there are no HDMI connectors, which is somewhat bad, then use SCART, RCA and others connectors.
Installation and configuration
First, let's install the antenna. An indoor antenna is usually installed on a window. External antenna You can try installing it on a balcony or mounting it on a bracket near a window if you live near the TV tower. Lay the cable from the antenna to the receiver. If the signal is weak enough, or the TV tower is located in the other direction, the antenna must be installed on the roof of the house. Point the antenna towards the TV tower; to do this, just look at the direction of neighboring antennas.Unpack the receiver, connect the cable from the antenna to it, then connect the cable from the TV. Next, connect the receiver to power, turn it on and perform initial settings: language, time and time zone, etc.
If the model supports automatic channel scanning, then you can use it. If there is no automatic search, then manual mode need to choose necessary channels two multiplexes. These channels may differ in regions, most often these are channels 35 and 45.
Find the channel of the first multiplex and scan it, and then select the channel of the second multiplex and scan it too. The fact is that each of these channels contains its own package of 10 channels. By the way, it is in this menu settings, a signal level scale will be displayed. If the signal level is low, you can rotate the antenna, choosing its best direction, based on the scale indicators.
That's it, now you can enjoy watching terrestrial digital television.
In this article we will tell you how to properly connect digital television to the TV. Here we will talk only about connecting terrestrial and cable TV (setting up satellite broadcasting is beyond the scope of this material).
Attention! All cable connections described below should be made with the power to the devices turned off to avoid damage to them.
How to connect digital terrestrial television to your TV
Many modern Smart TVs have a built-in receiver for decoding digital signal. For example, a line in the characteristics of a DVB-T/C/S TV says that this model The TV supports reception of terrestrial, cable and satellite digital television without an additional set-top box. However, some standards are already outdated, so a TV with a built-in DVB-T module will not be able to receive digital channels the current DVB-T2 standard.
What is needed to connect digital television
- Antenna UHF waves (UHF) or a universal all-wave antenna designed for different bands.
- Digital tuner (receiver) DVB-T2 or TV with a built-in module of a similar standard.
- Connecting cables.
Separately, it should be said about the broadband Polish antenna, the so-called “grid” or “pole”. If you want to use it to receive digital television, you will need a little modification, namely replacing the standard amplifier with a balancer. This will allow you to cut off the unnecessary range and tune it exclusively to UHF waves. Or purchase a “Pole” with a symmetrizer already installed.
Since not all TVs have a built-in tuner, we will look at the connection diagram using a digital set-top box. Such instructions will be more universal and suitable in most cases.
1. Connect high frequency antenna cable To antenna input digital set-top box, designated by the letters IN or INPUT.
2. To connect digital set-top box to your TV, we recommend using HDMI. This interface is designed specifically for digital signal and provides the most high quality Images.
To connect a digital television set-top box to an old TV You can use the AV connectors for an RCA cable (tulip) or a coaxial connector. There are no other options for older TVs.
3. How to set up digital television channels on your TV
Connecting a TV with a built-in digital tuner follows a simplified scheme:
- Connect the RF antenna cable directly to the antenna input of the TV.
- Activate in the TV menu digital tuner.
- Produce automatic setup digital channels.
How to connect digital cable TV
To connect this type of TV, you need a digital cable or universal (hybrid) receiver. Unlike regular broadcast, it is equipped with a special PCMCIA slot for a CAM module with an access card that allows you to unlock paid package channels purchased from a cable television operator.
Many modern Smart TVs with a built-in digital receiver already have a PCMCIA slot, so there is no additional equipment in this case it is not required.
You can also use a special card reader to read CAM modules, but due to the large selection of hybrid digital receivers, these devices are used less and less.
Otherwise, to connect a digital television set-top box to your TV and configure digital TV channels, follow the instructions described above, since almost all connectors on the receivers are identical. Unless in in this case Instead of an HF antenna cable, the provider's cable is connected to the input of a digital set-top box or TV.
How to connect two or more TVs to a digital set-top box
Ideally, one digital receiver means connecting one TV to it, so the optimal, although not the cheapest, option would be to purchase a separate receiver for each TV. In this case, the RF antenna cable is connected to a splitter with two or more outputs, and then the signal goes separately to each receiver. The diagram of such a connection is shown in the figure:
You can also simply connect two TVs to one digital set-top box (receiver) using free connectors. For example, HDMI is for one, and tulips are for another. It should be remembered that in this case both TVs will receive the same decoded signal. Therefore, the image on the screens will be synchronous. In addition, you will need long cables to allow you to separate the TVs into different rooms.
Another way is to use an RF modulator, which will supply a separate decoded signal to each TV through a divider. But often the cost of such a device is several times higher than the price of a conventional digital terrestrial tuner.
Frequent connection problems
| Description of the problem | Possible causes and solutions |
|---|---|
| The TV does not see the digital set-top box. |
|
| Half of the channels are missing, there is image noise. | Probably the setting has gone wrong. Try running auto search again or make manual adjustments. |
| There are no 2-3 channels from the list. | Preventative work may be underway. You may also need to update the software of your TV or digital set-top box. |
| All channels are gone, retuning does not help. |

From January 2019, Tatarstan, together with the entire country, will finally say goodbye to the television “analog”. Specialists from the RTRS branch in Tatarstan told Tatar-inform correspondents about what needs to be done to switch to digital television.
On which TVs can you watch digital TV?
The republican branch of RTRS emphasized that for residents of the republic the costs of switching to digital broadcasting will be minimal. Default to free (without subscription fee- approx. T-i) and the public package will include 20 top Russian TV channels.
“It is important to understand that any television can be connected to digital terrestrial television, it’s just that the connection method may be slightly different for different devices,” noted specialists from the RTRS branch in Tatarstan.
If we talk in simple words- the newer your TV, the easier it will be to connect digital TV. The most questions arise from owners of common analog TVs that use a kinescope. Most of these devices were released long before the digitalization of domestic television. But even such old-timers can be transferred to “digital”, representatives of RTPC RT assured.
First of all, they advised getting an antenna (how to choose one is described below). Experts have divided all televisions into three types, depending on the generation.
The most modern models flat-panel TVs support the DVB-T2 signal transmission standard by default - all necessary equipment(receiver - approx. T-i) is already built into the body of the device. Therefore, to convert them to “digital” you just need to directly connect the antenna.
In older flat-panel TV models (produced before 2013), built-in digital receiver it may not turn out to be. To find out about this, just look at the device passport and find in it a mention of support for the DVB-T2 standard. If it is not there, you need a separate set-top box (receiver).
A separate receiver will definitely be required for older analog TVs with a picture tube. So that these and previous models devices worked with digital TV, you need to buy a set-top box-receiver with DVB-T2 support. On the one hand, you need to connect an antenna to the set-top box, and on the other, the TV itself.
When is an antenna not needed?
Antenna - necessary component when working with digital TV. Her separate installation not required in several cases. For example, if your house has a collective antenna. In this case, you need to find out from the management company of your home whether this antenna supports the DVB-T2 format. If yes, then you can safely connect such an antenna. If there is no “digital” support in the common house antenna, then you can write an application for its installation.
Another case when installing an antenna is not necessary is if you are a cable TV user. Such TV viewers have the right to enter into an agreement with the cable TV operator for free viewing of 20 public channels. If the operator refuses, then you can safely write a corresponding complaint to Roskomnadzor.
You also won't need an antenna if your satellite dish or simply there is no TV. In other cases, it is impossible to do without installing an antenna, concluded the RTPC RT specialists.
How to install an antenna for digital TV?
According to representatives of RTPC RT, there should not be any particular difficulties with installing the antenna. But there are several important points that need to be taken into account during the process. All of them are related to the distance to the nearest TV tower.
When the distance increases to 20 km, a more powerful one will be required outdoor antenna, though without an amplifier. It will be required if the nearest TV tower is located at a distance of 20 - 60 km from your home.
“The antenna must be UHF to receive digital terrestrial television. It is also allowed to use all-wave antenna, which will allow you to simultaneously watch regional analog channels and digital TV,” the RTPC explained to reporters.
At the same time, experts especially emphasized that there is no need to install a powerful antenna if you live next to a television tower. Due to the high signal strength, it will work worse than room temperature.
How to choose equipment in a store?
Before you go shopping for an antenna or digital set-top box, you should remember that sellers are obliged to accept the product back if for some reason it does not suit you. You can also talk to your neighbors on the landing - perhaps they have already switched to digital and will tell you suitable model antennas and attachments.
“Any attachment will do. The minimum price for them is now around 700 rubles,” specialists from the RTPC RT told reporters.
They added that more expensive receiver options will differ from budget models only in the presence of additional functions - watching video from a flash drive, recording TV programs and others. There will be no fundamental differences in the devices.
What to do when you have all the necessary equipment?
There are two options here. In the first case we're talking about about modern flat-screen TVs with DVB-T2 support (with a built-in set-top box - approx. T-i). After connecting to the antenna, you just need to press the auto-tuning button on your remote control. The electronics itself will find available digital channels.
If the TV is older, then you first need to connect the set-top box to it. This can be done in several ways - through a four-channel “tulip” cable, a SCART connector, or through a more modern HDMI connector - the type of connection will depend on specific model your TV. In older models, “tulip” is mainly used, in the most modern ones - HDMI.
After connecting the set-top box through one of these connectors, you need to click on the “auto search” button on it. In this case, the TV must be switched to AV mode (the corresponding button is located on the TV remote control). After this, the set-top box itself will scan the available TV channels and you will be able to watch digital television.
Discuss()
Digital terrestrial television is slowly but surely replacing analog television. In Ukraine, from the fall of 2018 to the spring of 2019, they plan to completely turn off analogue television. As far as I know, in Russia they also plan to turn off analogue TV at the beginning of 2019. And despite the fact that many people watch satellite TV, cable, or IPTV, many residents will have to look alternative options. Otherwise, the TV will simply stop working and receive a signal at one point. And instead of our favorite TV channel, we will see the hiss of the TV.
Of course, instead of analog television, digital terrestrial television has long been working well, which everyone can watch absolutely free (in Russia there seems to be a separate paid package). For free viewing all available popular channels which we looked at earlier. Moreover, there are more channels, and the picture and sound quality is much better. In connection with the transition to T2, many people have a question about what is needed to receive digital terrestrial television. How to receive a T2 signal and what devices are needed for this? What should a TV be like? Is it necessary to buy a T2 set-top box (tuner)? Which antenna will do? There are a lot of such questions. In this article I will try to answer the most popular of them.
Digital terrestrial television - what is it, what are the advantages and what is the difference?
I will try to explain everything in simple words. Terrestrial television is television that is transmitted using a signal that is broadcast using television towers.
Terrestrial television can be divided into:
- Analog. Old format, which is now being actively disabled in many countries. Including in Ukraine and Russia.
- Digital. A new format that allows you to receive and watch channels in best quality. Digital format less sensitive to interference. Can broadcast more channels.
Until recently, our TV using conventional antenna received analogue television (maybe they still accept it if it hasn’t been disabled in your country yet). As technology develops, analog television is simply outdated. Therefore, it began a long time ago smooth transition to digital television in DVB-T2 format.
DVB is a set of digital television standards. DVB-T is an outdated format. DVB-T2 is a new format.
Digital TV has many advantages over analogue. The first and very big plus is signal compression. Due to this, it increased maximum amount broadcast channels, which can be broadcast. At the same time, the quality of image and sound has improved, which is simply necessary for modern, large TVs. It also became possible to transmit information about a TV show, information about the following programs, etc.
Depending on the country, channel broadcasts are divided into packages. In Ukraine, for example, you can watch 32 channels for free digital quality. These are 4 packages (multiplex) of 8 channels. For example, because of bad signal catches only 2 packets (16 channels). In Russia there are two free packages. Each broadcasts 10 channels.
It's like there aren't many options. If we want to watch terrestrial television, then we will have to switch to T2. Or install a satellite dish, connect IPTV, or cable TV. In villages and small towns, most likely there are only two options left: satellite TV, or terrestrial T2. Which is better is up to you to decide. Perhaps later I will write an article on this topic.
What is needed to receive a DVB-T2 signal?
Let's return to the topic of the article - the equipment that is necessary to receive digital terrestrial television.
- Or a TV with DVB-T2 support.
- Or a special T2 set-top box (tuner).
- Antenna.
Everything is simple here. If we have old TV, which does not have a built-in tuner that supports the DVB-T2 format, then you need to buy a separate set-top box that will receive the T2 signal, process it and transmit the finished picture to the TV. The set-top box itself can be connected to almost any TV. Even to the "pot-bellied" one.
TV with DVB-T2 support
Your TV may be able to receive a T2 signal. In this case, you do not need to buy a separate set-top box. Or you can connect the antenna directly to the TV, start searching for digital channels and enjoy watching.
In our countries, TVs with DVB-T2 support began to appear sometime after 2012. Therefore, if your TV was purchased before 2012, then it is unlikely to have T2 support. You need to look at the specifications and check. Information about the availability of DVB-T2 support may be indicated on the box or in the documentation. If you didn’t find anything there, then simply enter your TV model in search engine, open some popular online store (or better yet, the official website of the manufacturer) and look what digital standards supports the tuner in your TV.
It looks something like this:
We look at the characteristics of the LG TV on the official website (broadcast system):
Or go to the settings of your TV and select channel settings (search) from the menu. He should ask you which channels to look for: digital, or digital and analog. Before doing this, you will most likely need to select the type of antenna: Cable (DVB-C), or Antenna (DVB-T).
Now, if there is something in the settings about searching for digital channels, then most likely there is support for T2.
It seems to me that it is possible that the TV only supports DVB-T, but not DVB-T2. Therefore, it is better to look at the characteristics of a specific model.
T2 set-top box for watching digital terrestrial television
If the TV cannot directly receive the T2 signal, you will have to buy a special set-top box. Many people call it a receiver. This is a small box that connects to the TV. An antenna is connected to the set-top box. Next, we perform a simple setup (search for channels) and watch digital TV.
There are a lot of such consoles. There are even separate online stores that sell only equipment for receiving the T2 signal. They even sell sets for receiving digital television (set-top box + antenna). The choice is very large, as well as the difference in price. And here you probably have a question: what is the difference between these consoles? The difference is in functionality, size, design, operating system, performance, etc.
- All these set-top boxes can receive a T2 signal. This seems to be their main task.
- In most receivers (even in the cheapest ones) There is a USB port into which you can connect a USB drive and watch videos, photos, or listen to music.
- Broadcast TV recording function.
- There are many models that can be connected to the Internet (via LAN or Wi-Fi, usually using a separate USB adapter). This makes it possible to watch videos on YouTube or other services. Watch IPTV, use a browser, etc.
- There are T2 set-top boxes that run on Android. All the functionality of this is already available there. operating system. With this device you can turn your regular TV in Smart TV.
There are a lot of differences. You should always carefully look and study the characteristics of a particular receiver. When I bought the T2 receiver, I didn’t understand all the nuances. Then, when I bought it, it turned out that the TV has a built-in T2 receiver. Well, nothing, later I connected it to another TV. By the way, I have a Strong SRT 8204. It seems to be one of the most budget ones. But nothing, it works.
This set-top box can be connected to almost any TV. If you have an old TV, you can connect the set-top box using a triple tulip cable. If your TV has HDMI, then of course you need to use an HDMI cable to connect. The image quality will be much better. An HDMI cable usually needs to be purchased separately.
Antenna for DVB-T2 reception
You can receive digital terrestrial television with almost any antenna. You don't need any special antenna for this. You can easily use the antenna that you have installed, through which you have previously watched analog television. Any decimeter antenna will work without problems. So-called " Polish antenna" will also work for T2.
Of course, it all depends on how far the tower is from you and what the terrain is like in your area. If you live in a city where a tower is installed, then most likely everything will work even without an antenna. But I think a piece of wire will be needed. In this case, you can use an indoor antenna without an amplifier.
If the tower is far away, then you will need an antenna with an amplifier. Or you will have to install an external one decimeter antenna for receiving digital terrestrial television. They also come without amplifiers or with amplifiers. When bad reception You may need to raise the antenna onto a mast.
Please note that if the antenna is powered, a power supply may not be needed as most T2 receivers can supply power to the antenna. Typically, this function is enabled in the receiver settings. You need to look at the specifications or instructions. Your receiver may not have this feature.
The antenna must be correctly connected and directed strictly towards the tower. You can easily find information on the placement of DVB-T2 signal transmitters in your country and region on the Internet.
conclusions
To start watching T2, you usually only need a receiver. Since you most likely already have an antenna. If your TV is not very old (especially if it has Smart TV), then you may not need to buy anything at all. Check if your TV supports DVB-T2. I have already told you how to do this.
If your TV does not have a T2 receiver, you will have to buy a set-top box. There is a large selection, I think you will find something. Well, then we connect the antenna and TV to the set-top box, and in the settings we start searching for channels. If the channels are not found, then check all the contacts on the antenna, point the antenna towards the tower (after looking at the location of the tower before). You may need more powerful antenna, or amplifier.
Be sure to leave comments. Share your experience and ask questions!
If we compare the quality of modern digital television and analogue, the latter is noticeably inferior. The use of digital channels and special signal coding allows you to transmit image and sound in excellent quality. Precisely because good characteristics pictures and stable signal transmission, more and more users are giving preference to digital television.
Plus, now each user has the opportunity to create a list of channels available for viewing. No more uninteresting channels “in the load”. Only the most necessary things. It should be mentioned that it is digital television that supports signal transmission high definition. Now HDTV content has become even more accessible. We will look in detail at how to connect digital television to a TV and what will be needed for this?
I would especially like to dwell on the equipment. First of all, you need to understand that there are several ways to connect. From specific method The equipment you need also depends.
The easiest way to enjoy digital on your TV is to use digital terrestrial television. From the equipment you will need a UHF antenna ( UHF antenna, external or internal), the TV itself and possibly the set-top box. One of the frequently asked questions is which TV is suitable for digital television, and are there certain technical requirements? Your TV must support the DVB-T2/MPEG-4 broadcast standard, that is, have a built-in digital tuner.
If your model does not meet these requirements, do not be discouraged. There are digital set-top boxes that connect to the TV using functional connectors and allow you to work with the DVB-T2 standard. It is worth noting that currently on the market there is big choice digital set-top boxes different price and with different characteristics. Therefore, you can choose as budget model, and a device with additional capabilities.
If your TV has a built-in digital tuner, simply connect a UHF antenna to it. After this procedure, start the channel search procedure. If you don't have a tuner, use a digital set-top box. Please note that it is best to connect the set-top box to the TV using HDMI or DVI connectors. Otherwise, you will not receive a signal in Full HD resolution. Using the appropriate cable, connect the connectors of the TV and set-top box. After this, connect the UHF antenna to the set-top box. The procedure is completed.
If you have the opportunity, you can connect digital cable television. To do this, you will need a cable receiver, as well as a specific access module. If the TV has a built-in digital cable receiver and a PCMCIA slot, then in order to use digital television, you just need to connect a special access module. Perform all operations with the equipment turned off. Insert the CAM access module into the slot PCMCIA TV. After this, insert the smart card into the CAM access module according to the instructions. It is the purchased smart card that provides full access To paid channels in digital quality.
Digital satellite television
This is perhaps one of the most time-consuming ways to connect digital television to a TV. To connect, you will need a satellite dish (in common parlance - a dish), a special bracket (we will use it to mount the antenna), a converter (it will irradiate the antenna), satellite receiver, as well as a cable for connecting the TV to the receiver and satellite dish to the TV. Such a solid set of equipment may cost more than cable digital television.
The whole difficulty of the connection lies in the fact that it is necessary to choose the correct antenna diameter and point it at the satellite. All procedures for installing and configuring the antenna are provided by the service provider, but if you wish, you can consult and perform all the manipulations yourself. The operator from whom you will order services for connecting digital satellite television will tell you the specific type of connection.
conclusions
We examined the technical aspects of connection. Do not forget that all manipulations must be carried out with the equipment turned off to avoid damage and short circuits. Let us remind you that it is very easy to find out whether your TV supports digital television. To do this, you need to study the instruction manual in detail and specifications Your model. Exist special designations, characterizing the TV’s ability to work with certain broadcast standards. So the designation DVB-T2 means that the TV can receive digital terrestrial television, DVB-C - cable, DVB-S - satellite. We really hope that this article helped you understand in detail the question of how to connect digital television to your TV? Good luck with your connections.
