When it comes to buying a new TV, most people pay attention only to the quality of the transmitted image, as well as the technical characteristics on which it depends. The price of the device is also important. But the presence or absence of a digital tuner, as well as its type and quantity, is of little interest to anyone. Not many people pay attention to it. As a result, when there is a desire to connect and watch DTV for free, problems arise and you have to spend money to buy a DVB-T2 tuner separately.
Today we will look at what a digital tuner is, what it can be and how it works. This will allow you to approach the choice of a new TV more carefully and decide for yourself whether you need such a device built into the TV or not. Moreover, as already mentioned, a digital tuner can always be purchased separately.
What is DTV T2
Before considering the features and types of tuners that exist on TVs today, it is necessary to understand what this device is in principle and what it is for. A digital tuner is a receiver or, as it is also called, a decoder that allows the TV to directly receive various types of broadcast signals and decode them.
Many new TV models already have a built-in T2 digital receiver. In addition, there are divisions in which there are two tuners at once - T2 and S2. You can find out what type of device is built into your TV by looking at its technical specifications. If you have a built-in decoder that accepts a signal of a different format, then the necessary tuner can always be purchased separately.
External tuners are very popular today, since not many Russian citizens have the opportunity to spend a large amount of money on buying a new TV, and such a set-top box allows you to expand the capabilities of an existing device. The most popular are set-top boxes in the T2 format, which allow you to connect and watch, as well as the DVB-S2 set-top box. They buy it if they decide to install a satellite TV antenna, but there is no decoder of this type on the TV.
Broadcast standards
As already mentioned, the tuner built into the TV can receive one or more signals of different broadcast formats. Consider the most common options.
- DVB-T. Such a receiver can receive a digital television signal, which transmits a picture of a higher level of quality and clarity. To connect it, you need a regular TV antenna.
- DVB-T2. This is the second generation of DVB-T decoders, which differs from its predecessor in increased channel capacity, higher signal characteristics and its architecture. On the territory of Russia, this DTV signal format is mainly used. It is impossible to receive it through the DVB-T decoder, as these formats are incompatible.
- DVB-C. A very popular format that can decode a digital cable television signal. To start using it, you need to insert a provider card into the appropriate slot.
- DVB-S. With it, you can directly connect a satellite dish to your TV.
- DVB-S2. Like the T2, the S2 is the second generation of DVB-S receivers. S and S2 are also incompatible, so an appropriate decoder is needed to receive this type of signal. This format is distinguished by increased channel capacity and the use of new types of modulation.
When buying a TV, you should pay special attention to the labeling. So, you can see the inscription DVB-T2/S2. This means that the TV will be able to receive both terrestrial and satellite digital channels.
Features of DVB-S2 and DVB-T2
The built-in digital satellite TV tuner has certain features. In order to watch free available TV channels, it will not be enough for you to simply connect a satellite dish to your TV directly. You will also need to purchase an additional CAM module.
The fact is that without it you will not be able to view encrypted channels, but only those that are completely open. This is due to the fact that companies involved in the production of such TVs do not really think about this. In addition, it will be impossible to change the firmware or enter the code. External satellite tuners sold by us have firmware, in which all the necessary codes are already entered.

What is a digital media receiver. The principle of operation of the DVB-T2 digital set-top box. How to choose a digital media receiver for DVB-T2 and DVB-C? How to connect and set up the receiver. The best digital consoles.
A digital media receiver is a small device that receives a digital TV signal. After purchasing it, you will be able to watch digital channels on absolutely any TV.
Setting up a DVB-T2 on-air digital set-top box does not require special skills and efforts, which makes it even more convenient for consumers. There are two types of digital media receivers: home (stationary) and car. The former are needed to work indoors, the latter - in cars. Set-top boxes for DVB-T2 digital TV are functional, have a clear and user-friendly interface. The receivers support various video and audio formats, have a timeshift function that shifts the time of watching television programs.
The DVB-T2 terrestrial digital set-top box is a device for converting the signal that comes from a satellite dish and displaying it on a TV or PC screen. The main component for any digital media receiver is the central processing unit responsible for receiving, processing the signal, displaying the picture and writing data to the hard drive, which is the second important component for the receiver. Below is a block diagram for an on-air digital set-top box.
Let's consider it. At the first IF, the signal (range 950-2150 MHz) from the output of the LNA converter (LNV) is fed via cable to the SHF receiver (a unit designed to amplify and convert the signal to the second 480 MHz IF). Possible errors are corrected in the demodulator, the stream selected at the output is sent to the demultiplexer (it separates the total stream into video, audio and data) and decryption is performed.
In the MPEG-2 video decoder, video signals are decoded into decompressed digital signals, after which video signals are extracted in the form of such components: luminance (U), green (G), red (R), blue (B). The encoder of the color television system converts standards, which means that a television receiver can be connected to its output, which operates in one of three standards for analog television: PAL, SECAM or NTSC. An audio decoder can output both digital and analog signals. The microprocessor controls the demultiplexer - decoder and selects the signal in case of implementing an interactive communication system, and it also selects integrated data packets. As for the digital control module and the IR sensor, they provide the ability to remotely control the on-air DVB T2 digital set-top box.
How to choose a digital set-top box
Now on the market there are a lot of different digital set-top boxes DVB-T2 (terrestrial TV), DVB-C (cable TV), DVB-S2 (satellite TV). Receivers differ in functionality, price, and many want to make a choice in favor of the optimal device without overpaying money. Below is an overview of the criteria for selecting the best option.
First, let's talk about set-top boxes for terrestrial digital TV. As for standards, you should pay attention to set-top boxes that support the DVB-T2 standard (MPEG-4 encoding). If we talk about digital media receivers that support HDTV video and 3D capabilities, then you should not opt for such set-top boxes if your TV does not support such functions. Pay attention to whether the audio-video signal processing formats are supported: MPEG4 (AVC / H.264) SD / HD / MPEG-1 Layer I / II, MPEG-2 Layer II, MP4 and MP3, AAC, AVI, WAV, MKV, MPEG, JPEG, DivX, USB PVR.
Regarding the functions, it is worth making a choice in the direction of a set-top box that supports TimeShift, this makes it possible to watch TV programs on a delayed basis. The duration of the recording directly depends on the amount of memory of the storage device that can be connected via the USB port. It is important to have hardware buttons on the front panel to control the main functions so that your device does not turn into a useless brick due to the loss or breakdown of the remote control.
Pay attention to connectors. It is also best to opt for a set-top box that has a sufficient number of USB ports. If you need a receiver to watch TV in high definition, then it is desirable that the tuner has an additional HDMI connector, or at least a component (YPbRr).
If you use cable analog TV, then you should not buy a set-top box yourself. First, contact your provider. Find out the conditions and method of connecting cable TV. Usually the company itself connects everything and uses a receiver model specially stitched for a cable network.
How to connect and set up a digital receiver
To begin with, before setting up, you should connect the DVB-T2 set-top box to the TV. The diagram is shown below.
To set up the receiver requires a minimum of effort. The main thing to do is to set up channels. Go to the channel search menu and select auto search. Don't forget to set the country correctly. After a few minutes, the set-top box will find a certain number of channels. In the next menu item "Video" we set the necessary settings (mostly those that are by default are suitable). In the "Time" item, set the region and time zone. Next, set the menu language, subtitles and audio. In the "System" tab, you can set parental control and password. You can also choose to restore the factory settings, update the software, or read the information about the set-top box. In the "USB" item, you can select the playback format (music, photo, video) and configure PVR.
It is worth noting that each digital media receiver has its own setup features, the above is a general overview.

Digital television has taught us that picture and sound quality must be consistently high. Connecting to it is simple: for this you need DVB-T2 - a set-top box for digital television. It serves to receive a signal and transmit it to a TV without a built-in tuner, while an antenna must be used. Such a receiver may have different functionality and, accordingly, cost.
Which model to choose?
To buy a digital TV set-top box that meets your needs, and not overpay for extra features, pay attention to the following features:
- Support for HD formats. If you are going to watch high-definition digital TV (HD, Full HD), make sure that this support is available in your device.
- Recording of TV programs. In order not to miss your favorite TV show or movie, even if you were not at home at the time of the show, buy a receiver with a TV recording function.
- Connectors. A DVB-T2 digital set-top box for TV is usually equipped with standard inputs and outputs. However, before buying, it will not be superfluous to look at the list of connectors for the model you like. Make sure it has HDMI, which is popular today, through which the device connects to the TV.
- Additional functions. When choosing a particular model, keep in mind that the more functionality it has, the higher the price. So choose what is right for you. This can be a pause function during the broadcast, built-in radio, timer recording programs, TV guide and other options.

The introduction on the territory of Ukraine of terrestrial digital television of the DVB-T2 standard made it possible to significantly expand the zones of reliable reception of the signal from TV towers, in comparison with the analog signal. Also, the ease of setup and installation of T2 did their job, they have become much more popular than satellite TV with MFA channels.
Let's move on to the practical side and talk about the direct installation of all the equipment necessary to receive a digital DVB-T2 signal. Many modern TVs are already equipped with an integrated DVB-T2 receiver, in which case it is enough to find out the position of the repeater, point the antenna at it and scan the available channels using the TV. In the case of a simple TV, the installation and connection of T2 is somewhat different, we will discuss it now. To install T2 in the standard version, you will need:
- DVB-T2 digital receiver
, the form factor you need, for example, for hidden installation with a remote IR sensor, etc. The choice is now huge, 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.

- UHF Antenna , in practice, the so-called "Polish antennas" are often used, you can also purchase an antenna manufactured by Konvaliya, Margoon, etc., you just have to take into account that the antenna must be taken with a margin of gain, since it is possible to predict 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 be powered both from and from an external power supply.
- Cable, regular TV , almost anyone will do, but it is better to take with a percentage of filling with a braid of 50%.
- RCA or HDMI cable to connect receiver to TV may be included or must be purchased separately.
Connecting digital T2 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 anything here, I’ll just say follow the manufacturer’s recommendations, and at least first 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 the T2 digital receiver to the antenna will also not cause much difficulty, the manufacturer and standardization make this process simple and it is quite difficult to make a mistake here.
When connecting, it’s hard to confuse something, RCA - the cable is connected simply, 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 receiver model it is located on the left side. 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 power supply connector, for this model it is located on the side panel.
This completes the connection of the T2 receiver. Next, you need to turn on the TV and receiver. By pressing the “AV-TV” switch button on the TV remote control, we switch from the antenna jack to the “tulips”, on newer TVs we select the input to which the receiver is connected. The following should appear on the screen:
