How to connect digital TV to TV. How to set up digital channels on a Samsung TV. Cable digital television

Digital television is increasingly winning the hearts of people all over the world. The familiar analog signal will be replaced by a wide-format digital signal. What's the difference between them? The first transmits data continuously at the maximum values of the amplitude of wave oscillations, which creates a large scatter, which is fraught with interference on the screen. The second signal is transmitted according to the rules of a discrete function, that is, oscillations only receive certain values. This improves the signal quality, there is no interference on the screen and the data is protected from outside influence or interception.

Digital television has made it possible to watch programs in a new format, the image quality is several times better than analogue television. Some modern channels transmit video in HD quality.

What is a digital tuner

To receive digital video on your TV, you need to install additional equipment:

special antenna (maybe satellite dish), which will take digital signal or cable (fiber optic, twisted pair);
a receiver (tuner) that decrypts digital data and transmits it to the TV (can be built into the TV).

A TV tuner is a special receiver designed to receive and decode a data signal into various formats, with information displayed on the screen. Can capture video and radio digital waves. Available as a separate device or a microcircuit built into a TV or computer.

Receivers are classified according to a number of parameters:

to support television signal standards;
by the method of connection to a PC or TV;
on interaction with operating systems.

The tuner accepts several digital stream formats (data are given for Russia):

DVB-T, DVB-T2 works with broadcasting.
DVB-C is intended for cable television.
DVB-S, DVB-S2 - designed to receive a signal via a satellite dish.

There are many models of digital set-top boxes on the market. They differ in cost, functionality, and design. Yet the main task receiver - to receive data in DVB-T2 format; all devices fulfill this purpose.

Each receiver has a USB port (the number of connectors depends on the cost). This makes it possible to connect storage devices (removable hard disks, flash drives, mobile devices) and watch videos directly from them.

In more expensive models, it is possible to record information from terrestrial television to storage devices.

There are also tuners with the ability to work via the Internet. The connection is made via a twisted pair cable or via a Wi-Fi radio signal. This expands the possibilities of viewing channels that are available in World Wide Web(eg YouTube).

IN latest models tuners have the function of working with operating Android systems. This allows you to broadcast Smart-TV (technology for connecting to a network of televisions via mobile devices or PCs).

To select a set-top box for viewing programs (in Russia there are 20 free channels digital broadcasting), you need to decide on the functionality of the receiver. What actions should the tuner perform, what signal will the device receive? Does the cost of the set (set-top boxes and antenna) affect the choice of item?

It is important to remember which signal will be broadcast and processed by the device. Mostly television programs are received in MPEG-4 quality, but some large companies switch to HD format.

There are receivers built into the TV. They have the same functions as an external decoder.

What kind of TV is needed for digital television? In Russia digital television appeared relatively recently, so citizens rarely think about the possibility of purchasing equipment with some additional functions. You can purchase a screen model with a built-in receiver so as not to buy additional equipment.

There are undoubted leaders in the global TV market that produce models with a built-in decoder card. They work independently, therefore additional equipment not required to watch digital television.

The most popular companies whose models after 2015 have a built-in decoding chip:

Samsung;
Sony;
Philips;
Apple;
Panasonic;
Toshiba.

There are other manufacturers, but availability additional features needs to be clarified.

IMPORTANT: besides Apple, which are compatible only with equipment of their own brand, other companies produce universal TVs. These brands can work with devices from any other company (excluding Apple).

Which TVs have a digital tuner? Developers annually try to make life easier for users. The more modern the model, the more programs and opportunities she has.

Which TV models support digital television? The presence of a built-in tuner does not guarantee viewing of over-the-air broadcasts. When choosing, you need to clarify the data transmission standards (for a simple antenna, satellite or cable TV).

Do all TVs support digital television?

What should a TV be like for digital television? It should be noted that not all TVs can receive a digital signal, even modern models. Old screens equipped with a kinescope or ray tube are accepted only analog signals. They will not receive a digital signal without a receiver.

IMPORTANT: Before purchasing external equipment for older models, you should make sure that the connector matches modern standards. In simple words, after purchasing a set-top box, the cable may not fit into the receiving holes in the TV. This rarely happens because the slot for a regular antenna is used.

Which TVs support digital television without a set-top box? Opportunity to work with digital video has been developed since 1990, but the first TV models with digital support appeared in 2004. They were very rare and expensive.

Which TVs receive digital television without a set-top box? Plasma and liquid crystal models began to be mass produced complete with decoders later than 2010. In Russia, similar screens appeared later than 2013.

Today, almost every screen supports the ability to receive digital data. Exceptions are inexpensive models with minimum set functions.

IMPORTANT: it is necessary to remember that there are a number of countries in which terrestrial digital TV is broadcast in different bands than in Russia. For example, in America it is ATSC, in Japan and South America- ISDB-T, and in neighboring China - DTMB. IN European countries The broadcast channel is in DVB-T (an outdated format, but there are companies that broadcast on it) and DVB-T2 formats. Russia uses DVB-T2 frequency.

When buying a TV outside Russia, you must choose a model with DVB-T2 support.

How to tell if your TV has DVB-T2

Which TVs accept digital signals without a set-top box? When choosing a TV (or checking an existing TV for the presence of a tuner), you need to look at the parameters in the instructions for the device. It is also possible to find a description of the model on the Internet. For example, on official resource manufacturer. For this manipulation you need to find the make and model of the TV. On the device, the model is indicated on the back of the screen.

IMPORTANT: identify the label correctly. If you choose a TV that supports DVB-T, which DVB format-T2 will not work. An error in one number can become an unpleasant discovery in the future.

There are differences in the decoder itself: will it work from satellite dish(these are waves with a characteristic - DVB-S or DVB-S2). For cable digital television, you must have a tuner that decodes DVB-C information. Or the consumer will be content with regular broadcasting on the DVB-T2 wavelength.

In specialized stores, the main parameters are indicated on the price tag, and information can also be clarified with a consultant.

In the case when all identification marks and the instructions itself are lost, then you can check the presence of the receiver by scanning the channels. For this you need an antenna. Distinguish digital broadcasting from analog it is easy: the first excellent quality, shows the name of the channel, as well as the previous and subsequent channels.

Which TVs don't need a set-top box? Some before purchasing digital kit television people are wondering: which is better - a built-in tuner or an external set-top box. The embedded microcircuit has a number of advantages:

The signal is processed faster. The video sequence does not “stick”, the pictures do not jump. There is no interference that occurs in the cable between the set-top box and the TV.
Quick channel setup. To work, you need to go to the TV settings, connect the antenna, and start scanning. With a peripheral tuner, you need to configure the connection to the TV.
One remote control is used instead of two. On the receiver, channels are switched with its own remote control, which is not entirely user-friendly. The sound is controlled by the TV remote control. Eat universal devices, but this is an additional expense.
No extra wires. The external tuner uses an additional socket.
The external decoder must be located within the range of the remote control. For example, if the screen is mounted on the wall, then you need to install the console not far from it (sometimes an additional shelf is required).
If you buy a TV and an external receiver, it will cost more than a screen with a built-in tuner.

It is profitable to buy a set-top box when you already have a TV itself, but without the support of a digital decoder.

IMPORTANT: you should not buy a microcircuit in order to integrate it into your TV. It is impossible to do this without special equipment and knowledge.

Of course, there are advantages to an external decoder. For example, it powers the antenna itself.

In this article we will tell 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 to the devices turned off to avoid damage to them.

How to connect digital terrestrial television to your 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 says that this model The TV supports reception of terrestrial, cable and satellite digital television without additional console. However, some standards are already outdated, so a TV with a built-in DVB-T module will not be able to receive digital channels the current DVB-T2 standard.

What is needed to connect digital television

Antenna of the decimeter wave range (UHF) or a universal all-wave antenna designed for different bands.
Digital tuner(receiver) DVB-T2 or a 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, you will need a little modification, namely replacing the standard amplifier with a balancer. This will allow you to cut off the unnecessary range and tune it exclusively to UHF waves. Or purchase a “Pole” with a symmetrizer already installed.

Since not all TVs have a built-in tuner, we will look at the connection diagram using a digital set-top box. Such instructions will be more universal and suitable in most cases.

1. Connect high frequency antenna cable to the antenna input of the digital set-top box, indicated by the letters IN or INPUT.

2. To connect your digital set-top box to your TV, we recommend using HDMI. This interface is designed specifically for digital signal and provides the highest image quality.

To connect a digital television set-top box to an old TV you can use the AV connectors for RCA cable(“tulip”) or coaxial connector. There are no other options for older TVs.

3. How to set up digital television channels on your TV

Connecting a TV with a built-in digital tuner follows a simplified scheme:

Connect the RF antenna cable directly to the antenna input of the TV.
Activate the digital tuner in the TV menu.
Produce automatic setup digital channels.

How to connect digital cable TV

To connect this type of TV, you need a digital cable or universal (hybrid) receiver. Unlike regular broadcast, it is equipped with a special PCMCIA slot for a CAM module with an access card that allows you to unlock paid package channels purchased from a cable television 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.

Also for reading CAM modules you can use a special card reader, but due to large selection Hybrid digital receivers, these devices are used less and less.

Otherwise, to connect a digital television set-top box to your TV and configure digital TV channels, follow the instructions described above, since almost all connectors on the receivers are identical. Unless in in this case Instead of an HF 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 with two or more outputs, and then the signal is coming separately for 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 another. It should be remembered that in this case both TVs will receive the same decoded signal. Therefore, the image on the screens will be synchronous. In addition, you will need long cables to allow you to separate the TVs into different rooms.

Another way is to use an RF modulator, which will supply a separate decoded signal to each TV through a divider. 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 digital set-top box.	cables are damaged or incorrectly connected; The required signal source is not selected in the TV settings.
Half of the channels are missing, there is image noise.	Probably the setting is wrong. Try running auto search again or make manual adjustments.
There are no 2-3 channels from the list.	Preventative work may be underway. You may also need to update the software of your TV or digital set-top box.

So, you want to connect digital television. What needs to be done for this, and what to pay attention to? I will answer all your questions. I’ll say right away that we're talking about about terrestrial digital TV(set-top box, antenna, air), about cable - this is not here)

How to connect digital TV? It's actually very simple!

I suggest you simple algorithm, following which, you can easily connect and configure 10 or 20 digital channels on your TV. But, since each step has its own nuances, I wrote separate articles on them. Carefully study everything that is written here, and you will be happy - free digital television in your home. All links open in a new window.

So, let's go.

The first three steps when connecting digital TV, or “Where to start”?

Read this brief introduction on a topic written by me. This way you will get a rough idea of the issue in general.
Watch it using terrestrial digital TV. Maybe you expected more or something different? If you are not satisfied with what is broadcast there, you can close this site and continue with your business)
Make sure that there is a digital TV nearby that operates in the DVB T2 format, and that you are within the broadcast area of one of them.

If the first three points did not discourage you, then let’s continue. More likely, next steps will require money, so check the coverage area well and think about whether you are doing all this in vain.

All you need is a TV (I paid for 1100) and (with an amplifier I charged 700 rubles). In total, the issue price is 1,800 rubles, which pays for itself in a year of cable TV subscription. And if you don’t buy an antenna, then that’s great. And the TV may well already have a built-in receiver for connecting digital TV.

Further steps to connect the “digital”

If something didn’t work out and we didn’t catch anything, then don’t despair.
If nothing helps, then call or write an email to the local customer support center. I wrote, and they actually answered my questions from there. Well done!

Connecting digital television is not launching a ship into space, and I think that it is available to everyone who has such a desire and very little money)

Here is a short manual with a bunch of pitfalls. I hope you found it helpful.

In most apartments and even private houses within any small town problems with reception quality TV signal now there is almost none, since it has been carried out almost everywhere cable TV. In the majority apartment buildings Cities with over a million people may have several cable TV operators, which gives residents a pretty good choice.

But as you move away from the city center, the availability of cable TV High Quality gradually “reduces to nothing.” And outside the city, as a rule, cable TV completely absent.

Therefore, most summer residents are content to watch at most a few channels of terrestrial television, which they can catch on. Moreover image quality often leaves much to be desired. Especially if the summer cottage is located far from the emitting terrestrial television station, then on the TV screen you can see a lot of interference from "snow" to "streaks" and black and white image instead of a color picture.

In most of Russia, terrestrial television is still transmitted to analog format. This method of signal transmission has one significant drawback: the signal-to-noise ratio drops significantly with distance from the emitter.

With distance from the television center, noise (interference) begins to dominate more and more over the main signal. This is precisely what manifests itself in the appearance of “snow” on the screen. If the cottage or village is very far from the transmitting station, then the noise will eventually interrupt the signal completely, and It becomes impossible to watch a TV channel at all.

Now the country is introducing the transmission of TV signals in digital format, and over time it is planned to completely abandon the transmission television programs in analog format.

What is the advantage of digital TV over analogue?

Transmission of a signal “encoded in digital” compared to direct transmission in analog format gives several advantages:

Increasing the noise immunity of transmission and recording paths of television signals.
Reducing transmitter power.
Significant increase in the number of TV programs transmitted in the same frequency range.
Improving image and sound quality in TV receivers.
Creation of TV systems with new standards of image decomposition (high-definition television).
Creation of interactive TV systems, when using which the viewer has the opportunity to influence the transmitted program (for example, video on demand).
Function "To the beginning of transmission".
Archive of TV programs and recording of TV programs.
Transmission of various additional information in a TV signal.
Select a language (more than the usual two) and subtitles.
Extension functionality studio equipment.
Possibility of adding radio to multiplexes

But there are also some flaws:

Freezing and scattering of the picture into “squares” when insufficient level received signal, the data is either received with 100% quality or restored, or received poorly with the impossibility of restoration.
Almost complete signal fading during thunderstorms.
Even a transmitter with a power of 10 kW and a transmitting antenna height of 350 m provides reliable reception at a distance of 50 km, and as a result, the need for a larger number of transmitting centers than with analog TV (more frequent placement of transmitting antennas).

Since we are discussing from the point of view of an ordinary user mainly only image quality, then we can highlight only one main feature of digital terrestrial TV over outdated analogue:

Digital TV is very resistant to interference. To do this, the signal is encoded with some redundancy. The digital tuner will output perfect picture even if there is large quantity interference And it will do this until the signal-to-noise ratio drops to a minimum, when the signal arrives at the very edge of the equipment’s capabilities.

That is, in analogue broadcasting As the signal level drops, you will see the picture worse and worse. In digital broadcasting, you won't notice the signal drop until the tuner is no longer able to recover the lost pieces of the image, and it "disintegrates into squares" and then disappears completely.

Types of digital television

Based on the transmission channel, digital TV can be divided into four types:

Cable (DVB-C)
Terrestrial (DVB-T2)
Satellite (DVB-S)
Internet TV (IP TV)

We will not consider cable TV and IP television in the country due to their great rarity. But satellite and terrestrial digital television broadcasting in the countryside is relevant.

Moreover, satellite DTV has been used by consumers for quite some time, and in particularly remote areas there are no alternatives to it at all. We will look at it in our separate article.

But on-air DTV began to enter the lives of gardeners and summer residents relatively recently. Let's talk about him in more detail today.

Terrestrial digital television in the country

On-air network digital television broadcasting in the Russian Federation still in the process of construction and currently available mainly near large cities. But it already covers a significant part of the dacha areas. Therefore, the issue of connection becomes very relevant in Lately.

How to connect to terrestrial DTV?

If you want to try connecting digital television to your dacha, first you need to determine does your site fall within the coverage area of one of the DTV transmitting antennas?. The location of the site will determine how your TV receiver will pick up the digital signal.

Most reliable way Find out by asking your neighbors summer cottage, perhaps some of them are already watching TV channels in digital form. Then you can be completely sure that “the signal is reaching you.”

If no one in the area has yet heard of digital TV, then you need to try to find out whether your site falls within the boundaries broadcast radius of a local emitting DTV station.

Coverage area

The broadcast radius of a DTV station usually lies within 20-50 km, depending on the terrain and building density. On average about 30 km is reliable reception zone.

Each region has its own local organization - DTV operator, which is responsible for building and maintaining the network. On their website you can usually see the locations of broadcast stations and even coverage maps. Or you can get information from them by phone or written request.

The DTV network in the Russian Federation is being built by the Federal State Unitary Enterprise Russian Television and Radio Broadcasting Network.

Each region has a division of this organization.

You can call and find out everything by phone numbers in your region from the page.

If you are lucky and you find out that your dacha is located in the digital broadcast zone, then it’s time to decide necessary equipment for DTV reception.

Equipment

So, you already have a TV in your dacha, a plot in the DTV broadcast zone. Let's start installing digital television at the dacha. What else is needed to receive a signal? At a minimum you need an antenna.

Antenna for digital television reception

Universal HF/UHF antenna for digital TV reception

If a digital TV tower is nearby, then it is enough indoor antenna . I will say even more, I personally confidently caught a DTV signal in the city of Ufa on a meter-long piece of wire.

If the signal level is not so ideal, then you will need to install an antenna at your dacha to receive digital channels. Nowadays, most antennas on sale are well suited for this, since they support reception of signals in the decimeter range (UHF/UHF).

For example, you can install the antenna “GAL”, “Locus”, “Zenith”, “Meridian”, “Ether”, etc. I bought my antenna in Auchan for 1000 rubles.

If you know the exact location of the DTV tower, then everything is simple: point the antenna on her and that's it. Usually this is enough to catch a signal and watch digital TV without problems.

If the exact direction is not known, then you need to gradually rotate the antenna until you find the most better position. Most digital set-top boxes have signal level and quality indicator, which is displayed on the TV screen and from which you can find the best antenna position. This is usually done by two people: one person rotates the antenna, the second monitors the signal level.

When you have found the maximum possible signal level and the antenna is installed in the desired direction, you need to search for channels on the set-top box.

Setting up digital television at the dacha

The easiest way is to find the “Auto search for channels” item in the set-top box menu, and then the set-top box will do everything itself: it will find all available digital channels and number them in order.

List of digital terrestrial television channels

Now the interesting part: what channels does digital television show for free??

Since my dacha is in the suburbs of Ufa, and I am writing from my own experience, it means that I am considering digital terrestrial television in Ufa. But as far as I understand, list of channels throughout Russia will be the same with rare exceptions, so the information will be useful to everyone, not just residents of Bashkortostan.

At our dacha the DTV shows 20 channels: 10 at each multiplex.

List of digital television channels

Here full list channels in Ufa:

1	"First channel"
2	"Russia 1"
3	"Match TV"
4	"NTV"

I hope I helped you understand all the nuances of digital TV. If you have any questions, write, I will definitely try to help you.

From January 2019, Tatarstan, together with the entire country, will finally say goodbye to the television “analog”. Specialists from the RTRS branch in Tatarstan told Tatar-inform correspondents about what needs to be done to switch to digital television.

On which TVs can you watch digital TV?

The republican branch of RTRS emphasized that for residents of the republic the costs of switching to digital broadcasting will be minimal. Default to free (without subscription fee- approx. T-i) and the public package will include 20 top Russian TV channels.

“It is important to understand that any television can be connected to digital terrestrial television, it’s just that the connection method may be slightly different for different devices,” noted specialists from the RTRS branch in Tatarstan.

If we talk in simple words- the newer your TV, the easier it will be to connect digital TV. Most of the questions arise from owners of common analog TVs using a kinescope. Most of these devices were released long before the digitalization of domestic television. But even such old-timers can be transferred to “digital”, representatives of RTPC RT assured.

First of all, they advised getting an antenna (how to choose one is described below). Experts have divided all televisions into three types, depending on the generation.

The most modern flat-panel TV models support the DVB-T2 signal transmission standard by default - all necessary equipment(receiver - approx. T-i) is already built into the body of the device. Therefore, to convert them to “digital” you just need to directly connect the antenna.

In older flat-panel TV models (produced before 2013), built-in digital receiver it may not turn out to be. To find out about this, just look at the device passport and find in it a mention of support for the DVB-T2 standard. If it is not there, you need a separate set-top box (receiver).

A separate receiver will definitely be required for older analog TVs with a picture tube. So that these and previous models devices worked with digital TV, you need to buy a set-top box-receiver with DVB-T2 support. On the one hand, you need to connect an antenna to the set-top box, and on the other, the TV itself.

When is an antenna not needed?

Antenna - necessary component when working with digital TV. Her separate installation not required in several cases. For example, if your home has collective antenna. In this case, you need to find out management company your home, does this antenna support the DVB-T2 format. If yes, then you can safely connect such an antenna. If there is no “digital” support in the common house antenna, then you can write an application for its installation.

Another case when installing an antenna is not necessary is if you are a cable TV user. Such TV viewers have the right to enter into an agreement with the cable TV operator for free viewing of 20 public channels. If the operator refuses, then you can safely write a corresponding complaint to Roskomnadzor.

An antenna is also not required if you have a satellite dish or simply do not have a TV. In other cases, it is impossible to do without installing an antenna, concluded the RTPC RT specialists.

How to install an antenna for digital TV?

According to representatives of RTPC RT, there should not be any particular difficulties with installing the antenna. But there are several important points that need to be taken into account during the process. All of them are related to the distance to the nearest TV tower.

When the distance increases to 20 km, a more powerful one will be required outdoor antenna, though without an amplifier. It will be required if the nearest TV tower is located at a distance of 20 - 60 km from your home.

“The antenna must be UHF to receive digital terrestrial television. It is also allowed to use all-wave antenna, which will allow you to simultaneously watch regional analogue channels and digital TV,” the RTPC RT explained to journalists.

At the same time, experts especially emphasized that there is no need to set powerful antenna, if you live near a TV tower. Due to the high signal strength, it will work worse than room temperature.

How to choose equipment in a store?

Before you go shopping for an antenna or digital set-top box, you should remember that sellers are obliged to accept the product back if for some reason it does not suit you. You can also talk to your neighbors on the landing - perhaps they have already switched to digital and will tell you suitable model antennas and attachments.

“Any attachment will do. Minimum price they now cost around 700 rubles,” specialists from the RTPC told reporters.

They added that more expensive receiver options will differ from budget models only by the presence additional functions- watching videos from a flash drive, recording TV programs and others. There will be no fundamental differences in the devices.

What to do when you have all the necessary equipment?

There are two options here. In the first case we are talking about modern flat screen TVs with DVB-T2 support (with a built-in set-top box - approx. T-i). After connecting to the antenna, you just need to press the auto-tuning button on your remote control. The electronics itself will find available digital channels.

If the TV is older, then you first need to connect the set-top box to it. This can be done in several ways - through a four-channel “tulip” cable, a SCART connector, or through a more modern HDMI connector - the type of connection will depend on specific model your TV. In older models, “tulip” is mainly used, in the most modern ones - HDMI.

After connecting the set-top box through one of these connectors, you need to click on the “auto search” button on it. In this case, the TV must be switched to AV mode (the corresponding button is located on the TV remote control). After this, the set-top box will scan itself available TV channels and you will be able to watch digital television.
