How does a digital TV set-top box work?

Most owners of modern televisions are switching to digital television, which is more suitable for new models both in format and in the transmitted signal quality. All of them are capable of supporting a digital signal. But users of older models have to deal with the need to install a digital set-top box. But not everyone knows exactly what functions it performs and how to choose it correctly. Having studied all the parameters and indicators that characterize these devices, you can choose the ideal model that is right for you.

What is a digital set-top box and how does it work?

A digital set-top box or receiver is a device with which the analog signal entering the TV is converted to digital. This allows you to enjoy all the benefits of digital TV not only on smart devices, but even on the earliest models of TV receivers, which eliminates the need for additional expenses on purchasing modern gadgets.

In most cases, receivers also perform other additional functions that make the operation of the device as comfortable as possible. In order to connect the set-top box, you do not need to have any special skills. You just need to use a few wires and install it in the right place, for example, even on the TV itself, if it is of the right width.

IMPORTANT! Please note that the functionality and capabilities of the device vary depending on the manufacturer and the specific model. That is why you should be very careful when choosing and consult with the seller before purchasing.

TV receiver functions

Despite the fact that sometimes the capabilities of set-top boxes vary significantly, there is one common set of functions that almost every model has. Of course, the main function remains converting the signal to digital from analog, improving image quality and gaining access to more channels, but there are other advantages:

1. The presence of an HDMI connector, through which the highest quality signal is transmitted.
2. Possibility of connecting a hard drive. This comes in handy if you can't watch a program on schedule or just want to save it for later.
3. Having a browser to access the Internet - this way you can search for any information in a full-fledged browser, watch or download movies on the big screen, and even communicate on social networks.
4. Possibility of video compression in MPEG-4 format.
5. Several USB connectors to which you can connect a flash drive, for example, to view photos or videos taken by the camera.

And these are not all the possible functions that can be provided by console manufacturers. But the benefits of purchasing a receiver are obvious.

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:

1. 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.
2. 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.
3. 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.
4. Interface. Most devices have a standard interface, but more expensive models have additional slots or other advantages.
5. 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.

The principle of setting up a TV tuner

After connecting the set-top box, some users have questions about how to configure it and get more channels. To do this, you will need to go to the settings menu, select the country and signal standard, and then start an automatic channel search. After this, a search will begin for all available channels that are available in your region.

If the number of channels found is too small, you can try manual tuning. To do this, repeat the previous steps, but instead of automatic search, select manual. Before doing this, be sure to delete previously found channels. Then you will need to indicate the search frequency for your city, which can be found on the Internet or checked with your provider. After the search is completed, save the data.

IMPORTANT! If you are not sure that you can configure and connect the receiver correctly, it is better to contact professionals who will quickly and efficiently carry out all the work.

Now you know what a digital set-top box is, what it is needed for and how to choose the right model. Once connected, you will be able to enjoy your favorite programs or series in the highest quality possible, while acquiring many additional pleasant features.
