The name HD (High-Definition) is familiar to almost every person. Today, the definition of “high resolution” applies to everything that is in any way related to the broadcast of video material - smartphones, cameras, displays and even smart glasses. But most often we hear this concept together with television broadcasting - HDTV.
Modern transmission of television signals is carried out using digital coding, and in order for the picture to be displayed on the screen, a special converter is needed - a receiver for the TV. What kind of equipment is this? What are the broadcasting standards? And how to choose the best device? Let's try to figure it out.
Do you need an attachment?
When analog TV was cancelled, many users began to ask whether a set-top box was needed to watch digital television? If you want to watch channels in high quality, you cannot do without this device. The fact is that an indoor antenna does not provide good reception and transmission of a TV signal. In addition, it only picks up a few channels, usually 2-3. In addition, you have to walk around the entire room. Only in some places it is possible to catch at least some signal.
There are no such problems with the console. If you use it without a provider, you are guaranteed to receive 20 free channels approved by the President of the Russian Federation. If the connection is made, for example, through MTS or Rostelecom, the package will be expanded. The cost of the service in this case depends on the operator’s conditions.
In addition, the device can be placed anywhere. No need to carry the device around the room. It will provide a high-quality signal, regardless of the installation location. Therefore, to watch high-quality television, you cannot do without a set-top box.

How to choose the right receiver
Before purchasing a particular tuner model, study the main parameters by which you can choose the appropriate option. What should you consider when purchasing?
There are several basic characteristics:
- Resolution and broadcast type. In Russia, there are three types of broadcasting that are supported by set-top boxes. This is DVB-S/DVB-S2 (satellite broadcasting). The tuner connects to a satellite dish, DVB-C, broadcasting channels from the package of a regional provider. DVB-T2 - receives terrestrial digital broadcasting. Also, check the standards supported by your TV. It is important that the receiver and TV set are compatible.
- Multimedia format. Since the set-top box also serves as a player for other media files, pay attention to the formats that it supports. Of course, the best choice will be a receiver with the maximum number of them, but if you don’t want to overpay, think about which formats you use the most.
- Control. Before purchasing, make sure that operating the device will be comfortable for you and that you will not have to use several buttons to perform a simple action.
- Interface. Most devices have a standard interface, but more expensive models have additional slots or other advantages.
- Additional functions. It is better to choose the option whose functionality fully meets your needs. You shouldn't overpay for unnecessary features, but you shouldn't give up the opportunity, for example, to pause a program to watch later.
Connecting to a TV
How to connect and configure a digital receiver is described in the following video:
The digital receiver works in conjunction with a TV. Therefore, the first thing to do is to connect the devices. The procedure does not require special knowledge and skills. You can perform the operation yourself, without the help of specialists.
Instructions for connecting the set-top box to the TV:
- connect the receiver and antenna using the cables that are included in the set of equipment for displaying TV;
- connect the set-top box to the TV;
- plug the adapter into a power outlet.
And here are the most complete instructions that will help you switch to digital.
Please note that the connection can be made in several ways:
- Via HDMI connector. This is the easiest way to establish a connection. This connector provides good signal quality. The main thing is to use the correct cable. A cheap Chinese-made wire will not be able to connect devices well, which means the signal will constantly disappear, which will negatively affect the quality of television viewing.
- Connecting equipment using “tulips” is not the best option. The fact is that such wires do not provide a high-quality connection with the satellite and display the image on the screen. As a result, various interference will occur regularly. In addition, such wires cannot withstand high temperatures, so their use in private housing construction is not recommended.
- The USB-to-USB technology connection option is only suitable for certain models. The main advantages of this connection method are its affordable price. As for the quality of the output image, you should not count on a clear, stable picture.
As for how to use a set-top box for watching digital television, there is nothing complicated about it. Using the remote control, go to settings and start searching for channels in automatic mode.
After a few minutes, all available channels will be detected. You can switch them using the console remote control.

Criterias of choice
The capabilities of modern AV receivers produced by the largest manufacturers these days are quite difficult to highlight. That is why different models do not have obvious advantages that could be decisive when choosing a particular device. In any receivers, it is better to identify distinctive features that could be based on when choosing the optimal model.
Multichannel audio decoder
When selecting a receiver, you need to pay attention to the support, since the volumetric spatial effect of movie audio will largely depend on this. A good receiver must process all existing audio coding standards, otherwise the operation may not be correct
For example, if the decoder does not have the ability to contact the DTS signal, you simply will not be able to watch movies recorded in this format. This can only be done if you purchase an optional outdoor DTS decoder. That is why, when purchasing an AV receiver for a home theater, you should pay attention to the presence of decoders for standard digital formats.
Interfaces
The HDMI interface is considered universal; today it is a standard and is available on almost all models. The HDMI receiver provides multifunctional, full-fledged connection to the following types of ports:
- Blu-ray player;
- DVD player;
- game console;
- satellite receiver;
- PC or laptop.
This will significantly simplify the connection, as well as further broadcasting of multimedia files from any mobile devices.
Coaxial and optical connectors provide effective switching for a CD player, as well as a computer audio card.
Don’t forget about popular network interfaces, such as Wi-Fi, as well as the Internet and DLNA, which provide maximum freedom in organizing a multi-community.
Useful features
The vast majority of receivers allow you to process the incoming video signal: both analog and digital, including 3D. This option will be useful if you intend to play 3D content from devices connected to the receiver. Don't forget that all existing devices support the HDMI version.
These days, almost any setup offers HDMI 2.0 connectivity with 3D support at 4K resolution, can convert video to digital, and upscale to 4K. This feature is called upscaling, it allows you to watch low-resolution videos on a high-resolution display.
For novice users, an AV receiver model that provides its own sound auto-tuning system using a measuring microphone will certainly be useful.
No less useful when operating the AV receiver will be the presence of a graphical user menu, which is displayed on the display, as well as a learning remote control, which has its own memory for macro commands.
Amplifier
Here the principle of operation is very simple: the greater the power consumption, the more efficient the amplifier will operate. However, do not forget that too high power parameters are just as dangerous as insufficient ones. A suitable value for a room of 20 square meters. m will be considered a receiver of 100 W per channel; for small halls you can limit yourself to compact mini-receivers of low power
The perception of the audio largely depends on the output characteristics of this device; it is important that the power is distributed equally across all channels
Possible faults
Most often, the consoles work without interruption. Even if the connection was made by a person without experience or special skills, there should be no problems with the work. If you cannot establish a connection, there may be several reasons:
- The console is malfunctioning. If the device does not work, it is recommended to take it to a service center, however, in some cases it is more advisable to purchase a new device.
- Damage to any cable. You can try changing the wires and finding the channels again. If the search is successful, then the problem has been resolved.
- Problems with the operation of operator equipment. In this case, an icon indicating an IP address error will appear on the screen. To resolve the problem, it is recommended to contact your provider's technical support.
A set-top box for watching digital TV is a device that provides high-quality reception from a satellite and its transmission to a TV. Thanks to this, users have access to watch their favorite channels in high quality. Even a beginner will have no problems setting up the equipment.

Owners of modern digital TVs hardly think about why they need a set-top box. But for those who still have analog TV, it is necessary. Modern television broadcasting transmits digital signals that provide higher picture and sound quality than analogue ones. The TV receiver supports this standard on older TVs by converting the signal.
For people who are faced with the need to purchase such equipment for the first time, its installation and configuration may seem complicated. At the same time, you still need to choose the right model. We will examine all these questions in the article.
