NTRODUCTION
Ideally, one digital receiver means connecting one
TV to it, so it would be optimal to buy a separate
receiver for each TV, although not the cheapest
option. In this case, the RF antenna cable is
connected to a splitter with two or more outputs,
and then the signal goes to each receiver
separately [1,2]. Such a connection scheme is
shown in the figure 1:

Figure 1. Connection scheme
In addition, you can connect two TVs to one
digital set-top box (receiver) using free
connectors. For example, HDMI belongs to one,
tulips belong to another. It should be
remembered that in this case both TVs receive the
same decoded signal. Therefore, the image on the
screen will be synchronized. Also, you need long
cables to place TVs in different rooms [2-7].
Another method is to use an RF modulator, which
sends a separately decoded signal to each TV
through a splitter. But often the price of such a
device is several times higher than the price of a
traditional terrestrial tuner.

Table 1. Frequent connection problems
Description of the problem
Possible causes and solutions
The TV does not see the set-top box.
- damaged or incorrectly connected cables;
- the desired signal source is not selected in
the TV settings.
Half of the channels are missing,
there is picture noise.
Maybe the setting is not working. Try
restarting the automatic search or performing
a manual adjustment.
2-3 channels are missing from the
list.
Perhaps preventive measures are being taken.
You may also need to update your TV or set-
top box software.
All channels are missing, resetting
does not help.
- Defective digital set-top box;
- there is no signal from the TV tower;
- preventive works are being carried out.
It is difficult to imagine life in our world of
information technologies such as the Internet,
television and telephone. They are firmly
established in society and are an important
attribute of comfort. However, not all users know
how to connect to digital TV at home, so they often
face certain difficulties in setting up the device [8-
15].
General information
Recently, the popularity of digital television has
increased. Unlike traditional analog systems, this
type of television has many advantages, which
ensures the maximum quality of image and
sound.
And when it comes to connecting the "digital" to
the TV, many people think that it is a very difficult
process that requires professional help. But in
fact, everything is solved in a short time and does
not require much effort. It should be noted that
there are two types of digital television on the
market:
1. Cable.
2. Important.

Figure 3. Digital television
The first type is connected through a special TV
cable, and the second implies the presence of a
special antenna. If your TV does not have a digital
receiver, you will need to purchase one
separately. In stores, these devices are sold as a
special application [16-20].
If your home TV is already equipped with a digital
receiver, then it is enough to install a digital TV
smart card with the services of the provider for
connection. Then the device automatically
searches for a list of channels and stores them in
memory.
If you don't have a receiver, you need to buy a set-
top box. If your TV has an HDMI output, that's
great because it transmits the best picture and
sound.
Advantages of modern digital television systems
Despite the development of digital television
systems, many people still use cable television... It
also gives a good picture and unlimited
opportunities in choosing channels. However, for
such a TV you have to pay a subscription fee,
which, unfortunately, is constantly increasing. As
for digital equipment, then it has the following
advantages:

Figure 4. Signals in digital television systems; choosing the right recipients
To successfully launch digital television in a
private home, you need to purchase a special
device - a digital signal receiver. A device that
works according to the DVB-T2 standard is used
in its capabilities. As mentioned above, many
modern TV models are already equipped with a
built-in digital TV module, so the task can be
greatly simplified.
The capabilities of the device are determined by
its price range. Most receivers do not support
additional functions, and more expensive devices
have a small amount of memory and are able to
work with flash drives. In addition, some models
have the ability to record streaming video to
removable media.
Given the variety of digital receivers, choosing the
right option can be problematic. But if you follow
some tips and tricks, such a task can be solved
without much difficulty.

1.
If you ignore the technical aspects and
complex radio-mechanical features of
digital tuner models available on the
market, it remains to study their aesthetic
features and set of tasks. This approach
simplifies the selection of a quality device
and makes it successful.
2.
When you want to buy a digital receiver,
you need to decide in advance what
functions you need for the TV and what
you can give up. The most important and
necessary functions include:
3.
Ability to watch TV channels in DVB-T2
format.Tyunerdan audio fayllarni ishga
tushirish, tasvirlar va boshqa tarkibni
ko'rish uchun media pleer sifatida
foydalanish imkoniyati.
4.
Access to the global network (some
models are able to work with YouTube
media services, IPTV, online cinemas,
weather and news sources, etc.).
If the receiver model supports the above
functions, it remains to deal with some visual
features. When choosing the material of the case,
it is advisable to give preference to devices made
of high-quality metal or plastic. It is known that
these materials provide maximum reliability and
long service life.
On the front panel of the tuner there should be
various control buttons indicator lights... On the
back there should be USB inputs and other high-
tech interfaces.
