To receive a modern digital signal on an analog TV, you need an antenna and called a digital receiver or decoder. Both the antenna and the set-top box have certain requirements, observing which you can get a modern high-quality picture and the same sound.
Prefix
Do not rush to buy this device if digital television broadcasting has not yet been organized in your area. It is worth waiting for the start of work to test the decoder right in the store. A receiver is a compact electronic device that receives a signal from an antenna, then converts it and sends it to a television receiver. When buying a set-top box, first of all ask about its compliance with Russian requirements on the CETV network; the device must be optimized for the DVB-T2 broadcasting standard, support MPEG4 video signal and Multiple-PLP mode.
But this is only a minimal set: if you expect to receive paid programs, then you need conditional access (in the form of a CAM module), and if you plan to record programs, then the device must have a USB port. It will not be superfluous to be able to receive channels broadcasting in HD mode, i.e. high definition. Additional features of the set-top box include the presence of an indicator of the strength of the received signal, which helps to determine the most optimal position of the antenna.
Antenna
This may be absent altogether if the reception is carried out in the immediate vicinity of a powerful television transmitter. But this option is not available to all citizens, so an antenna is still needed. When living in relative proximity to the TV tower, you can use an ordinary room antenna: if your TV confidently received an analog signal, then it will be good at receiving a digital one. The main requirement for an outdoor antenna is reliable reception in the decimeter wavelength range (or UHF). Owners of a private house can put an antenna-receiving device on the roof, residents of multi-storey city buildings can use a balcony or try to achieve reliable reception by fixing the antenna on a wall or even a ceiling.
When living in areas of uncertain reception of a TV signal, it is necessary to install an external antenna on a mast, as which it is recommended to use a metal pipe with a diameter of at least 4 cm (do not forget about grounding). Its height is determined by the distance of the TV tower and the terrain. Also, good results are obtained by the use of television amplifiers operating in the analogue broadcasting method.
In this article, we will show you how to properly connect digital television to your TV. Here we will only talk 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 supply disconnected to prevent damage to them.
How to connect digital terrestrial television to a TV
Many modern Smart TVs have a built-in receiver for decoding a digital signal. For example, a line in the characteristics of a DVB-T / C / S TV indicates that this TV model supports receiving terrestrial, cable and satellite digital television without an additional set-top box. At the same time, some standards are already outdated, so a TV with a built-in DVB-T module will not be able to receive digital channels of the current DVB-T2 standard.
What is needed to connect digital television
- Antenna of the decimeter wavelength range (UHF) or a universal all-wave antenna designed for different ranges.
- 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, a little modification is required, namely, replacing the standard amplifier with a balun. This will cut off the unnecessary range and tune it exclusively to decimeter waves. Or buy a "Polish" with an already installed symmetrizer.
Since not all TVs have a built-in tuner, we will consider a connection diagram using a digital set-top box... Such an instruction will be more universal and will work in most cases.
1. Connect the RF antenna cable to the antenna input of the digital set-top box marked with the letters IN or IN.
2. To connect the set-top box to your TV, we recommend using HDMI. This interface is specially designed for digital signal and provides the highest picture quality.
To connect a digital TV box to the old TV you can use either the AV connectors for an RCA (cinch) cable or a coaxial connector. There are no other options for older TVs.
3. How to tune digital TV channels on your TV
Connecting a TV with a built-in digital tuner follows a simplified diagram:
- Connect the RF antenna cable directly to the antenna input of the TV.
- Activate the digital tuner in the TV menu.
- Perform automatic tuning of digital channels.
How to connect digital cable TV
To connect this type of TV, you need a digital cable or universal (hybrid) receiver. Unlike the usual terrestrial one, it is equipped with a special PCMCIA slot for a CAM module with an access card, which allows you to unlock a paid package of channels purchased from a cable TV operator.
Many modern Smart TVs with a built-in digital receiver already have a PCMCIA slot, so no additional equipment is required in this case.
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 TV set-top box to a TV and set up digital TV channels, follow the instructions described above, since almost all receiver connectors are identical. Unless in this case, instead of an RF 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 (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 the other. It should be remembered that in this case, the same decoded signal will be received on both TVs. Therefore, the image on the screens will be synchronous. In addition, you will need long cables to space the TVs to different rooms.
Another way is to use an RF modulator, which, through a divider, will supply a separate decoded signal to each TV. 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 set top box. |
|
| Half of the channels are missing, image noise is present. | The setting is probably out of order. Try to start auto search again or do manual tuning. |
| There are no 2-3 channels from the list. | Probably, preventive work is underway. You may also need to update your TV or set-top box software. |
| All channels are gone, reconfiguration does not help. |

A couple of years ago, many doubted that digital would come into existence so quickly. However, it is already safe to say that it happened. High picture quality, reliable signal - now this is the prerogative of not only cable networks and satellite TV. And naturally many people have a question: "How to connect digital television."
People who have heard about the introduction of digital TV in the region and who want to connect it, have many questions: what kind of TV do you need, what kind of set-top box, what kind of antenna should be, how much the set-top box costs. Let's try to answer all the questions, including such frequently asked questions as: "Connecting a set-top box for digital television", "How to connect digital television of VGTRK" and so on.
To immediately clarify some issues, I will say that digital TV broadcasting is completely free and is being introduced instead of the outdated analog signal in the SECAM standard operating in Russia.
Connecting digital television from a set-top box
We all connected video tape recorders, a DVD player, so the question of how to connect a digital TV set-top box will not put you in difficulty. Installing the set-top box is extremely simple, you just need to connect the antenna from the TV to the set-top box and connect it to the TV using a cable, through standard SCART, HDMI or "tulip" connectors without overpaying for a wizard call and installation, as is the case with satellite or cable TV.
A cable for connecting digital television needs a completely ordinary one. The set-top box comes with a cord with tulip-type connectors (usually), but if you do not have this type of connection on your TV or it is busy, then there is the possibility of connecting through other inputs, since there are enough of them on the set-top box. Connecting digital television to a TV can be seen in the figure
How to connect digital TV
All that is required to connect digital television is the purchase of a set-top box - decoder, and if your TV receives a signal of the decimeter range (UHF), then no additional equipment is needed. If not, you will have to spend money on a UHF antenna.
As for the price for a set-top box, it is low compared to satellite or cable and starts at about 1000 rubles. and higher depending on the options in the STB. The purchase of an antenna is also inexpensive.
Watching on TV
If you are interested in how to connect digital television without spending money on a set-top box, then it is possible to purchase with an internal DVB-T2 tuner, which is even more convenient, control with one remote control, you do not need to allocate space for the receiver. Picture tube (CRT) TVs with this tuner are not available, they are built only into modern LCD TVs. In this case, the connection diagram is even simpler, the UHF antenna is directly connected to the TV. It can be both external.
Digital cable TV connection
Unlike terrestrial, cable will not be free, although cheaper than satellite. Connecting this type of service is advisable when receiving terrestrial TV is impossible or extremely difficult. For example, the house is in the lowlands.
In this case, you need to find out if it is possible to connect cable TV and contact your provider. They will provide the equipment or, if it is possible to view it on TV, a special smart card that is inserted into the CI slot on the TV.
Conclusion
It is up to you to decide whether to connect digital television, but there are plenty of advantages for choosing it, especially for setting the number to.
After purchasing a brand new device with a large screen, an excellent solution is to connect digital television to a TV. However, many users do not know how to do this. It would seem like a simple process that won't take long. It is important to observe safety measures, therefore it is recommended to make sure that all devices are disconnected from the mains. Some modern ones have such an element as a receiver. He is responsible just for decoding the digital signal. It is easy to find out about standards support by looking at the model specifications. For example, if there is an inscription DVB-T / C / S, it means that a TV without any set-top boxes can be quickly set up for satellite, digital and cable TV. It is important to understand that some of the standards are out of date. If you have a TV with DVB-T support, then it will not be able to receive a DVB-T2 signal if you want to.
Necessary equipment
Before making such a connection, you will need to prepare the following:
- Indoor antenna;
- Receiver of DVB-T2 standard;
- Connecting cables.
Sometimes a universal antenna is used to connect digital television. Many models are all-wave and operate on different bands. As mentioned earlier, if the TV has a built-in T2 module, then a digital tuner is not required. Many are trying to connect via a broadband Polish antenna. It is not possible to do this, since there is no symmetrizer there. If desired, the presented element can be installed independently, and the standard amplifier is removed.
Connection process
- Get a decoder prefix. Such an element is required if you have a regular TV with antenna input or low frequency input.
- Connect the set-top box to the TV. This does not require a specialist - you can do everything yourself by connecting the two devices with a cable. As for additional equipment, the type of TV is taken into account. You will also need to find out information on the provider. There are different types of receivers, so don't rush to buy. Modern models are most often connected to the cable directly. There are also modifications that work through a satellite dish or computer networks.
- Choosing a service provider. Now there are many providers who will always help you connect to digital television and enjoy the content of new channels. Companies offer different terms and prices, so think carefully before connecting digital TV to your TV. Many dealerships are ready to arrange a whole presentation specifically for the buyer, and clearly show all the benefits.
- Payment for a package of channels. The user has to pay for connecting digital television every month. Some companies provide equipment installation services, but you can save on this.
- Switch to AV input. Once the equipment is installed and connected, it doesn't take long to set up the TV. If the set-top box is installed via the AV input, then the corresponding item is selected in the menu. Also, the set-top box can be connected via HDMI. In this case, this input is selected. The TV signal source is selected in different ways. If we consider the standard model, then it usually has an AV or SOURCE button. If there are no such inscriptions on the remote control, you will have to clarify the information in the instructions for the TV. Next, it's worth deciding on channel switching and volume control. To do this, you will have to use the remotes. Channel switching can only take place through the attachment. At the same time, volume control is successfully carried out both from the console from the set-top box and from the remote control from the TV. There is another trick in this business, which concerns the viewing of analogue programs. To quickly switch to other channels, you can connect the antenna input to the Cable Out connector on the set-top box. On some models, it is called RF Out. Then there will be only. All this should be done strictly according to the TV instructions.
- Setting up a digital set-top box. In order for the set-top box to work correctly for receiving signals, it must be configured. For this purpose, the user can use various functions. However, the good news is that most STBs do not need to be configured at all. If necessary, you can change the menu language. By selecting System Setting, it will also be possible to adjust the sound or remove subtitles. To make it work, you should select Language Setting and click OK. Further, using the arrow buttons, the desired line is selected and OK is pressed again.
- We are looking for channels on the TV. All channels can be found in the menu, where there is an item "Search for channels". By clicking on OK, you will have to set the basic parameters, namely the frequency, connection type, and flow rate. After that, the user selects the network search. If a colored level indicator appears on the screen, then everything is done correctly. After completing the search for channels, press the Exit button.
- Installing an access card. When the set-top box is connected via the Digital In, an A / V cable is used. Then the card is inserted into the slot of the set-top box. Typically, it is located on the back of the device. Upon completion of the work, you need to supply power to the console.
- We set the time. The local time on the console is set manually. To do this, when connecting set-top boxes, you should refuse to search for channels. The user is obliged to select the item "No" and click on OK. Next, the message "Installing systems" will appear. During the transition, the line "Local time setting" will be visible. Here you should immediately turn off GMT, and for this use the arrow buttons on the remote. When the work is completed, it is worth choosing Exit.
How do I connect multiple TVs?
Some people think that multiple TVs cannot be connected to the receiver, but this is not the case. Do not forget that the devices have several outputs. Thus, the user can device through tulips as well as HDMI.
The user will not be able to watch different channels. The use of an RF modulator will solve this problem. This element is engaged in providing a decoded signal to devices. The RF modulator costs a lot, so it is recommended to think a few times before buying.
Conclusion
Above is detailed instructions on how to connect digital television to a TV. The main emphasis should be on choosing a quality provider so that the picture is clear and without interference. It is recommended to immediately use the auto search function. The user can also go to manual settings and double-check the information.
The development of technology does not stand still: terrestrial analog television is being replaced by digital. Digital television uses a method of transmitting signal and sound by encoding it. For encoding, the mpeg data compression standard is used. There are several ways to become a user of such television: by connecting to terrestrial television and radio broadcasting or to satellite television. Which type of connection to choose depends on personal preference and where the signal is received.
Connection to terrestrial television
There are several ways to connect to TV. Regardless of the method, one of the main attributes is the antenna. Transmission of digital terrestrial T2 channels, despite the format and quality used, is carried out at frequencies of the decimeter range.
Different types of antennas are used depending on the location of the received device, compared to a television tower:
If you have a TV with a digital tuner installed in it, you just need to connect an antenna to its input and start scanning channels. A TV tuner is required that supports the type of signal coding used. IN recent times the standard type T2 is used. The received signal can be open or closed. A closed signal implies its special encoding. In order to be able to watch it, a decoder called the CAM module is used.
This module is an electronic map. Its appearance resembles an ordinary bank card with a special chip. Installation is performed through the Common Interface slot or through a special CI adapter (included with the TV), which is connected to the back of the TV. The card with the module is available separately from your cable TV service provider. The installation itself is straightforward and should be described in the instructions. It is important to note that it is advisable to carry out all actions with a television device disconnected from the electrical network.
After connecting, using the TV menu, channels are scanned automatically. When finished, all searched channels are stored in memory. The setup is complete.
How to connect the receiver to a TV
If the TV receiver does not have the required tuner for connection, you will have to use a special device: a set-top box or receiver with DVB-T2 support.
The name comes from the English set top box (box in the machine). This equipment is designed to receive a digital signal with its subsequent decoding and conversion to analog type. These devices are often referred to as decoders due to the use of mpeg-2 or mpeg-4 signal compression technology. The undoubted advantage of the set-top box will be the availability of great connectivity options. The main connectors that may be present on the tuner are analog RCA (tulip) or SCART (legacy), as well as digital HDMI.
The receivers themselves are different not only in appearance, but also electronic components. The components used allow you to use additional features, such as watching IPTV, connecting various storage devices, online cinemas, YouTube, game mode, etc. For this, the device is equipped with an additional network connector, USB ports, Wi-Fi module, bluetooth. Prefixes are also distinguished by types:
So, having any kind of TV, digital tuner and antenna at home, you can set up a high-quality signal broadcast.
First of all, you need a physical connection between devices. Connection is made depending on the availability of the available input connectors on the set-top box and tuner. For this connectors the corresponding cable is inserted into one and the other device:
If suddenly the same connectors no, it can be connected using various adapters. The adapter can simply consist of a wire and connectors, or it can have a complex electronic circuit inside, a controller. It can be active or passive, for example, RCA-SCART, RCA-HDMI, DVI-HDMI, etc. Preference should be given to digital transmission of HDMI signal, it provides the best resolution and, accordingly, image quality.
After the physical connection of the set-top box with the TV, the antenna is connected to the receiver and only after that all the required devices are connected to the 220 V power supply network.
It happens that you need to connect a modern television to an old television that does not have any connectors other than an antenna, that is, a high-frequency (HF) input. In this case, you can use a conventional VCR. The VCR has an RF input and output. To do this, its output is connected to the antenna input of the TV, and the tape recorder itself, using RCA or another possible connection, is combined with the tuner.
The second stage will be software configuration. On the TV, using the remote control, you switch to the used interface. According to the instructions for the tuner, it starts scanning the frequency range. After a certain period of time, all available channels will be found and stored in the receiver's memory. In the future, navigation between channels, sound adjustment will be made using the remote control set-top box. The system is ready for use.
When using a VCR, you first need to find on the TV at what frequency its signal is transmitted. Usually this is the 36th channel with a frequency of about 600 MHz, and then carry out the steps described above.
The peculiarity of the connection will be the use of its own type of antenna and receiver with a tuner supporting the DVB-S / S2 standard. The signal can be encoded in HD format (high definition video) and in mpeg-4, the former is preferable.
The antenna is a kitconsisting of the following elements:
- Plate. It has a different diameter, depending on the location of the installation and the type of satellite used.
- Converter. Collects the reflected signal from the dish. It can have several outputs.
- Dissek. Used to connect several convectors.
- Antenna cable. Connects to the receiver using the F-connector.
When choosing an antenna, special attention should be paid to the diameter of the dish: the larger it is, the better the signal reception. The best material for a plate is aluminum. It is less susceptible to corrosion and is lightweight. Converter location - offset ... This will enable the installation several convectors on one plate, increasing the number of visible satellites.
A characteristic feature when choosing satellite television will be the ability to choose a program package yourself, using one or another satellite. Another advantage is that you can also get the Internet via satellite. For example, Tricolor TV will provide Internet access at speeds up to 40 Mb / s for incoming traffic and up to 12 Mb / s for outgoing traffic.
The receiver connects to the set-top box in the same way, as in the case of on-air reception.
Connection example
Let us have a standard indoor decimeter antenna, a BBK LED 2272FG TV, a BBK SMP 124HDT2 tuner. The receiver is a product using the Ali 3812 chipset. Supports the DVB-T / DVB-T2, mpeg-2 / mpeg-4 standard, as an add-on has a built-in media player and the ability to record the received signal. Recording occurs through a connection to the USB port of any media.
Connect the antenna with a coaxial wire to the Ant-in socket. So, the antenna is connected, then you need to connect the digital set-top box to the TV. For this we connect the receiver to the TV using an HDMI cable. We connect everything to the 220 V. We switch the TV to the HDMI interface and scan the channels using the remote control tuner. After a few minutes, all available channels will be found. For example, in Russia 20 channels are broadcast, divided into two packages in the DVB-T2 format, multiplex. Both are free. There are 32 free channels in Ukraine, including 10 HD channels.
As can be noted, connecting and configuring digital TV broadcasting is not such a difficult task. Any user of a TV receiver or DVB receiver and antenna can install it.
