T2 How to set frequencies for all channels. How to set up a DVB-T2 digital TV set

After the advent of digital television, a large number of koristuvachs were saved by the transition to a modern format. What are the reasons? Crazy, try the novelty in the countryside, as well as in frequent discussions, which is a richer signal. Vidpovidno tse improve the quality of the picture. Ease of access also attracts new coristuvachiv.

Digital TV can be connected to kinescope models. For whom it is necessary to vicariously add additional accessories. І extremely modern models building televisions to catch this reception.

Near the Moscow region and the capital, the television and radio station "Ostankino" is propagating for critical access anonymous air channels. Tse allows you to receive a signal without additional registration and pay for Russian TV programs. The reception is available on individual antennas, roztashovani in the room, and so on.

Also, there are paid channels, for which there is a lot of money. How many channels are there today for digital TV in 2019? What is necessary to receive this signal? About the price.

How to receive a digital signal

Іsnuє chotiri options for connecting cost-free and pay TV channels:

• Cable. AT to this particular type reception of the signal is behind the auxiliary cable. The main minus is the subscription fee. This method is not available everywhere.
• Suputnikov. Here, the signal transmission is carried out through a satellite, with the help of a personal dish. There is a specific subscription fee. It is necessary to have a possession, recognized for satellite TB.
• Efirne (DVB TV channel). Terrestrial repeaters broaden the signal, which can be received by indoor or outdoor antenna. This connection option does not require additional financial investments. Manual way for watching TV programs in the format of daily movement.

Catch digital prefix(Dvb T2) channels are not as described above. The value of the signal is low. Take it easy with different rascals, as well as distant roztashuvannya on TV.

The lowest price is the reception of digital TV for an additional antenna, as it is installed and fixed independently. You can add different channels.

What is multiplex

Multiplex - the whole package in one digital package of different TV channels with digital telecom, which are combined before transmission over the channel and are distributed at the final receiving element (subscriber's receiver) with 1 or 2 TV channels.

Digital TV broadcasting in Russia in DVB T2 format offers 20 TV channels, which are divided into 2 packages, and are called multiplexes. Cost-free for revisiting digital channels - a subscription fee is charged every day. Koristuvachevi need only a TV set; a prefix with a decoder that accepts the DVB T2 frequency range (as such a decoder is available on TV) and an antenna.

Package No. 1 - the whole group of informational, new and developing channels (Russia 1 and 2, 1 and 5 channels and others).

This package is functional on a skrіz, de є digital TV broadcasting. At a glance, as if nearby, there is a working TV channel for digital format, you can choose all 10 channels. Koristuvach can be evil either all 10 times, or not one. The reason for this is that 1 channel is transmitted to the multiplex at the same frequency. The movement is carried out at a frequency of 546 MHz due to DVB-T2 jamming.

Drink frequently at this package The warehouse of channels is being changed. Competitions are held among the programs, after which the list can be reviewed. Frequency 498 MHz with DVB prefix.

Package No. 3 is being rolled out, but wine will be paid. Cheaper i simple option you need to speed up the cable and take over 100 channels for 200 rubles per month.

This package is practical for the test mode. It is also possible for someone to know the programs for maximum HD clarity.

What is needed for a review

To show digital TV channels, you need special equipment:

• Antenna;
• Set-top box for digital TV or TV set with DVB T2 tuner. The device can support the MPEG 4 standard and the functionality of the Multiple PLP mode.

If you want an antenna, you can select the antenna to a standard analog one. If you have a new model TV, you may also be able to integrate a digital tuner. At this time, there is no need to buy a prefix.

If you don't know what digital TV tuner your model has, take a look at the data sheet. As an option, enter at poke system name of the model.

Use two types of antenna attachments:

1. Active - if vicorous are connected, they are connected to the power supply. When the receiver is different, 5V is supplied through the new one. It is possible to fix it through the adjustment in the menu - "Antenna life". Do not start any active experiment, I will build a correct solution. Oskіlki with a close roztashuvannі bіla a good signal can reappear.
2. Passive - there are no additional additives here. Zadіyanі most often in zones with a stable signal. This option is the easiest for connecting a large TV.

Let's take a look at the features of choosing a digital tuner. Whoever sticks with such adjuncts in the past thinks that all prefixes are identical. Golovna Umova the right choiceє no pardons will be allowed in the key technical characteristics.

Іsnuyet and іnshі moments, yakі zdatnі infuse at a distance the functioning of the latitude of the functional warehouse:

• I don’t have any buttons on the outer panel, I’ll add it - I don’t need to goobov’yazu koristuvacha pratsyuvati more than with the remote control. Don't get practical.
• Like the tuner has a daily USB port, you can't play as a media player. For the obviousness of such a technique, you can put on the recording of TV programs, look at photographs and video clips.

Bring respect, which is a rozkishny variant - a prefix with an okrem block of life. Most often, this element is in the middle. Samoi common cause if the work of the tuner is concerned, the malfunction of the live block is important. At the time of the exit from the fret tsієї robili can be brought to service center or replace the new prefix. And the axle is an okremy block - it is possible to replace the components without any particular problems.

To improve the reception of the DVB-T2 signal, ring to request fahіvtsіv. But be a technically literate person, you can work independently. For whom do you need to know the frequencies digital channels DVB-T2.

Digital television broadcasting (CETV) is a special technology for transmitting images and sound for help digital coding signal from the selected digital channels. The main advantage of digital coding over analog is that which digitally secures the delivery of a signal with minimal costs. The video image of that sound is in some way protected from the influx of any external factors (reshkod).

Also an important advantage of the digital signal is the increase bandwidth channels to receive data. Digital data can be squeezed, after which we can transmit a large number of television channels at the best quality and with additional information (subtitles, audio tracks). DETV technologies include interactivity (possibility zvorotny zv'azku from gazers). The TV audience can not only look at the content, but also take part in the experiments, vote for anyone in some contests.

The transition to CETV is carried out in rich countries of the world. Residents of the most distant and sparsely populated villages and farms, who previously had little ability to watch only 1-2 channels, can now receive 15 or more channels on their TVs from a higher quality.

Digital terrestrial radio-television stations are put into operation according to the new European standard DVB-T2. To fight within the framework of a wild project for the transition from analog to digital on-air movement. In the krains of the SND (Russia, Kazakhstan and others), it is necessary to fight for special sovereign inquiries.

The main advantages of achieving digital modular radio and television stations to the DVB-T2 standard:

• increase the stability of the transmission paths and the recording of the signal to a different type of transition;
• change in tightness of gears;
• increase in the number of TV programs that are broadcast in the same range;
• raising the brightness of the image and the sound in televisions;
• creation of TV-systems with new image standards (high-definition television broadcasting);
• development of interactive TV systems;
• archive and recording of TB-programs;
• transmission of additional information from the TB-signal.

Private businesses, who want to work on paid rich TV programs, can use the service of receiving stations of digital terrestrial TV broadcasting "PID key". The technical capabilities of one station of medium intensity allow broadcasting a signal with a winder 20-50 km, tobto. near the zone of ohoplennya podpadaє place from the population of 50-100 yew. osib. Tse garniy option commercial solution for small cable TV operators, because there is no need for folding and expensive robots to lay the cable to the subscriber's apartment.

When DTTB is connected, subscribers will have access to more than 20 cost-free channels, as well as fixed-language federal channels.

Nalashtuvannya

For the reception of the TsETV, it is necessary to subscribe to the DVB-T2 / MPEG-4 standard, which supports the “Multiple PLP” mode, and turns on the UHF antenna. The antenna can be both collective and individual. Anteni boom different types and different tightness, they are to be selected in a fallow way before the transfer.

Clear radius of hoaxing of transmission stations:

• 10 W - 3 km;
• 50 W - 5 km;
• 100 W - 15 km;
• 500 W - 25 km;
• 1 kW - 30-35 km;
• 2 kW - 40 km;
• 5 kW - 40-50 km.

The possession for the receiving signal can be mentally subdivided into 3 types:

• televisions, which may be used by the DVB-T2 tuner;
• TV sets and set-top boxes (receiver) to the DVB-T2 standard;
• computer tuners to the same standard.

Nalashtuvannya, whether it be s variantіv possessing a few chimneys in others. For customization, you can ask a specialist, or you can work on your own by reading instructions on the Internet.

1. Connect the plug of the antenna cable and set-top box to the TV.
2. Launch auto-push channels - the TV itself will tune in to the current digital broadcast channel. If you manually set the time, you will need to enter the frequency of the DVB-T2 digital television (for example - 35 TB, 685 Hz).
3. Larger TVs and set-top boxes may have an indicator of the level and strength of the signal. This gives you the opportunity to optimally adjust the antenna. In quiet TVs, which may have a DVB-T2 tuner, everything is connected through the TV menu.

It is recommended to update software security subscriber's possession to the most current. You can work either in services or at home, so you can ask a specialist. PZ can be obtained from the official website of the maker.

Singingly, richly Russian koristuvachiv, like chirping to ethereal TV broadcasts, already chuli about step-by-step transition to digital movement all over the country. A lot of TV viewers do not suspect that it is necessary to work for the transition to digital TV, which is necessary to get additional equipment. For this material, I will write reviews on all power sources, as I plan to win digital TV on my TVs, even digital standard television broadcasting information technologies transform to a new service for the peephole.

The advantages of digital TV and the shortcomings of analog

The main shortfall of the analog signal is a weak overshoot, as well as a wide range of radio frequency spectrum, the movement of one channel is necessary. Therefore, on air, we were surrounded by a maximum of two dozens of color channels, and in cable lines, the average was 70. analog signal To do it smoothly, it is necessary for the service operator to work hard (for example, to implement the possibility of a quick connection and the inclusion of packets in the channels). In addition, analog TV needs to transmit a high tension over a large territory of hoarseness.

Digital signal of consolation tsikh nedolіkіv. The main advantage of digital TV broadcasting lies in the fact that the signal can be captured using the help of modern algorithms (for example, MPEG). For rahunok squeezing the signal frequency range One analog TV channel can hold up to ten digital channels with approximately the same picture quality. Those, how to encode and squeeze the signal, are the same standard. Today in Europe and Russia, the main family of standards is DVB - a product of the international consortium DVB Project. The family includes standards for satellite, terrestrial, cable and mobile television broadcasting, which are controlled by the level of compression, transient protection and other parameters (deposit from the vicorous medium of transmission).

The benefits of digital TB

• zavadostiykist, mozhlivist constraint;
• image brightness improvement (digital signal is less sensitive to overshoot, lower analog signal);
• a greater number of ethereal channels for analog channels.

Light standards of digital TV

In America, the ATSC standard is expanded by the Advanced Television Systems Committee, in Japan ISDB (Integrated Services Digital Broadcasting) is rapidly developing, Russia has gone the European way, adopting the DVB (Digital Video Broadcasting) standard as a basis.

Let's go digital

The mass transition to digital standards of television movement in the world was on the cob of the 2000s. In our country, the state-owned broadcasting channels have decided to switch to digital from 2009 as part of the federal program "Development of television and radio broadcasting in the Russian Federation for 2009-2015". As the only standard for digital traffic DVB-T2, which allows more digital channels to be placed on the frequency smuz, the lower DVB-T front end, but does not mean an increase in the distribution of the broadcast picture. HD-quality in the air is less than a check for a remote future one. Today, DVB-T2 transmissions are already available all over the country. Here, only the first multiplex (a package of 10 digital channels) is still included, in other areas another one is already available. Tse means that for the presence of a viable TB or a supplementary set-top box, you can freely receive and marvel at 20 channels at a decent level and mayzhe without a change. The program for the development of digital television transmission in Russia transmits an update of only a rozpodіlnogo and transmission setup. The viewers have to think about replacing the receivers on their own, even if it is necessary for the receiving signal of the terrestrial digital TV broadcaster. TV tuner DVB-T2, and such a transfer is less in . In order to receive a signal with old devices, TV viewers have to come and install a TV set-top box at home.

Video compression format in DVB standard

DVB standard- tse povene described the format of digital TV broadcasting, and the method of specific implementation of broadcasting. Within the framework of this standard, different video encoding systems (MPEG-1, MPEG-2, MPEG-4, etc.) can be changed, but not all stinks are summed. The widest compression format is MPEG-2 ( Krascha Yakist pictures) and MPEG-4 (may with the greatest grip). The Russian digital TV will have MPEG-4 compression. Televisions that support the MPEG-4 standard can also work with MPEG-2, but not the same way, MPEG-2, in its own right, is beaten by cable operators, not obmezheniem in the frequency mix and the picture, squeezed by the codec, is obviously clear.

Analogue antenna or satellite dish?

Robotic principle satellite dish . You need to buy and install a set of receiving signals: a “dish”, an access card to satellite channels and a set-top box (satellite receiver), which will ensure the transformation of the digital signal that is received into an analog TV. satellite receiver- ce attachment, which ensures the transformation of the DVB signal ( different systems decoded) in a format that is accepted by a TV set. To such a set-top box, you can connect the wire of a cable operator or a terrestrial television antenna. You may or may not need the former, but the shards of a lot of modern TV sets support the standard DVB-T, which means the confusion with MPEG-4 compression, and the receiving digital signal does not require a special antenna.

Sob do not change the TV, there is an alternative - CAM module. Vіn є svoєridnoy expansion card that is inserted into the TV set and gives it the functionality of the set-top box, but for this component the TV is to blame for the mother CAM-interface. Report about the CAM-module, I'll tell you about the digital cable TV.

Satellite platforms, which are officially used in Russia, are based on DVB-S and DVB-S2 standards. For the receiver, the antenna is correctly installed (the diameter of which should be based on the geographic location of the subscriber and the selected satellite), the receiver with a remote access card and the TV.

DVB-T2 - the new digital TV standard

DVB-T2 standard– all other generations of the European standard for terrestrial digital motion DVB-T. Increase the capacity of television services by at least 30% compared to DVB-T for the same infrastructure and frequency resources.

Advances to the DVB-T2 standard:

• increase in the number of channels of the broadcast package;
• the possibility of organizing a "massive" movement;
• the possibility of developing high-definition television;
• vivilnennya ethereal frequencies.

The adoption of the DVB-T2 standard in subscriber facilities creates a technological basis for this through the digital terrestrial television services and HDTV services. In the future, it is possible to introduce new interactive technology, and the possibility of a voice TV to become an analogue of Smart TV. Also, when buying a TV set, pay attention to support the DVB-T2 standard.

Different image building in digital television

Zvichayny TV signal maє "standard readability" ( Standard Definition,SD), as well as the variant of the reduced signal strength ( "promoted clarity") - 480p, 576p, 480i or 576i. The number denotes the number of pixels per height, and the type of scaling - through row (i) or progressive (p). The number of pixels across the width to lie in the difference between the sides of the picture, which causes more differences in the signal of increased clarity. Modern analog TVs have lesser options for SD. As long as your TV can support DVB-T, there will be no problems with confusion. Cable and satellite operators, as a rule, promote the other version of the “improved clarity” image. AT present moment DVB-T standard is getting old, and I'm going to replace DVB-T2. In Russia, the digital movement is on the air in DVB-T2 standardsіz pіdtrimkoyu standard vіsnennya video signal MPEG4 and mode Multiple PLP.

High definition television (High Definition TV, HDTV) – the best quality at the moment. HDTV is available in two versions - 1080i and 720p. The 720p format can be divided into 1280x720 pixels and progressively expanded, while the 1080i format can be divided into 1920x1080 pixels with a progressive expansion. Formally, the number of dots in a 720p double image is smaller, lower at 1080i, but in 720p one frame is formed in one pass, and in 1080i half. 1080i is more suitable for a video sequence with a minimum of disruption and a maximum of details, and 720p - on the other hand, for reasons not to be shown.

Digital cable television

In parallel with the reorganization of the terrestrial television broadcasting about the optimization of the frequency spectrum and the development of services, cable operators have also begun to work. In the field of cable TV broadcasting, a typical option for the development route is the launch of traffic in the DVB-C format (the version of the DVB standard for cable networks is reduced by a lower level of compression and a smaller change in the air standard, which is generally acceptable in the "cable"). When switching to “digital”, operators limit the possibility of gnuchka keruvannya content, for example, seeing packets of channels, blocking access to them for short-lived people. To decrypt the coded channels on the side of the subscriber, the so-called access cards are called. The skin coding system has its own stench, but the standard has a universal socket for connecting to a TV set or a CAM-module prefix for a single type of coding, in which an access card is installed.

Like DVB-T2, the cable version of digital TV is streamed in high definition (HD). But turn on some HD-channels at your own company, the skin operator will do it on his own. Significantly, that there are a lot of cable networks in Russia, where digital television has been launched, to promote HD channels. Dehto Navit by experimenting with 3D channels.

Setting for DVB-T2 and DVB-C receivers

For the review of the digital signal of cable lines, it is necessary to have it, as it accepts a valid standard. TV sets and set-top boxes with DVB-C support appeared for sale in 2007, so even though the rest of the years changed the TV receiver, then support for the cable version of the DVB standard is better for you, є. Ideally, to connect to a cable digital TV box, the owner of such a TV set needs to get a CAM module from the operator and insert an access card there. Ale oskolki kozhen the operator himself determines the policy of the work of the service, the CAM-modules are not propagated for an hour, and even then the subscribers need to add an intermediary attachment - a prefix with a smart access system (SUD), which is victorious by the operator. In most cases, such attachments are "imprisoned" only for one COURT.

If a cable operator broadcasts HD channels, then for their review, they can also receive HD channels. For a wild type of DVB-C (DVB-T/T2) subtrim, it does not mean Full HD subtrim (it allowed images of 1920 × 1080 pixels for both TVs and set-top boxes). A similar situation is with 3D channels.

The fact that the TV set supports the cable version of the DVB standard does not mean that it decodes and broadcasts the digital version. The delivery of the DVB-T2 support to our country has only started in 2012. So you can safely say that if your TV was purchased earlier, then the DVB-T2 standard is not clear. Cable boxes rarely accept DVB-T2. As if your TV device does not allow you to accept the ethereal "digit" for the mind, do not obligately change yoga. You can buy a set-top box for DVB-T2. Digital TV tuners which standard available from other vicons, including compact accessories for tablets and computers with USB sockets.

TV broadcast over the Internet

For transmission of a digital television signal between the operator, a link and a TV viewer will be connected to an Internet channel. Global TV projects can be shared on IPTV and OTT. If you want OTT - a different type of IPTV, call them to see how different services are. It is accepted that IPTV is a service in the middle of the operator, that it provides broadcasting of channels in real time mode, and OTT (Over The Top) is some kind of video service (not only broadcasting channels, but also a cinema, then rely on the Internet. A lot of broader operator platforms offer offensive options within the framework of one service, so it’s not possible to talk about the zhorst part of IPTV and OTT.

Setting for IPTV or OTT

To this day, TV makers have not yet come up with a single IPTV (OTT) service standard. For now, for the time being, those who look at the noise are picking up the available options for revisiting TB via the Internet:

• - Operators give supplements for the connection of the service. It's important that you can't speed up here third party solutions: the only one who can issue such a program for this particular company is an operator who provides a service.
• – the ability to connect to an IPTV TV depends on the availability of sockets for connecting a set-top box. The variety of such extensions, the truth, the thing, is lower in the ethereal prefixes. Іsnuyu navіt universalny aparaty, scho pratsyuyut at merezhakh different operators(reconnection can mean changing the firmware of the gadget, but if you don’t want to buy a new one), as well as playing the role of a home media center (for example, Dune HD).
• looking through channels on a computer Most of the "computer" package is smaller and there you can more easily stream HD-channels.
• television broadcasting on mobile attachments.

It is significant that HD, 3D channels can be broadcast in IPTV. But for their reconsideration, a prefix and a TV set are needed, yakі pіdtrimuyut і standard that allowed.

TV broadcasting on mobile devices

The idea of ​​a mobile TV tower became wider with the rise of a high-width mobile Internet and IPTV. It is possible to receive a TV signal potentially not only on specially broadcasting devices, but also for help, be it mobile annex, including smartphone or tablet. This time, there are a lot of call operators, who previously fired up IPTV (OTT) projects. For work with encoded content, operators link up with programs for mobile gadgets. Moreover, often such programs allow you to sign a subscription to a channel or a home set-top box. In the rest of the hour, anonymous projects appeared, which did not involve any call operator or provider, but rather to promote video content for short-range smartphones and so, like Amediateka, without IVI and others.

I am convinced that now you understand the difference between different types of digital TV: cable, Internet TV, satellite and broadcast.

Equipment for digital TV - all those you can buy in our shop. Our company has been working on the ethereal and satellite market since 2003 and most of our clients, we already know in guise.

We hope that in the online store of digital TV you can spend a minimum amount of time to get the necessary equipment.

The federal program handed over the coverage of digital television stations in the territory of Russia until 2015. Even today, many districts in our country can enjoy high-definition TV broadcasts in HD format. But the satisfaction is not accessible to everyone (everyone can marvel, but not everyone can dance))).

How to find out if your area is covered by a DVB T2 signal

Too simple! For whom we are going to the official website of the federal project, we have distributed the “Map of Cooling Merezhi”. You get an interactive map, so you can know your location or the closest population point, having entered them in a row of jokes, and choosing from prompts, what to drop:

At first glance, nothing folding, ale th here there are some nuances ( robbed on the knees and did not explain how the chim ) . Beastly respect for the right upper cut digital TV cards and wonder what is there.

For locking, the checkbox “ Puncti of the movement» - In essence, the TV channels are broadcasting in the DVB T2 format, and package of TV channels RTRS-1. Tse, then the first ten information channels of digital television. To marvel at you, take you to the TV motion zone, check the box “Motion zone”, as well as “TVK, frequency”, the card is turned out for fun colors:

"Zeleni" vezhi - robot workers. Immediately the frequency is the number of the channel on which the signal is transmitted

If it’s your district of farming, and nearby there is a “green” vezha, then everything is fine. Take the first ten channels and you will definitely get it. You will need the frequency of the turns at , so remember її, or rather write down, like the number of the channel on which you have to move the “number”.

But still not all.

On the right, the first and the other multiplex are transmitted by different waves and at different frequencies.

Tse means that, for example, the first ten channels you can already work on, and the axis of the other ten - more will be hanging and so often. It's easy to convert, go to the "RTRS-2 channel package" tab:

Another multiplex - yak bachimo, "green" cherries became less rich

They will show us again, and, moreover, better for everything, not all stench will be green, like a first-timer. So like the first vezh were for the first multiplex, then the stench has long been awakened and broadcast the first ten channels. And the axis іz is another multiplex higher. Vtіm, as there are no "green" cherries in your order, do not be embarrassed, click on the sіrih, there will be information about the stages of everyday life and the introduction to the day.

W special certificate I will say that the mother in the region has the first multiplex arriving from the port for 10 km, and the other axis - from the suidny region, for 45 km from the house. Well, it’s true, here the sound of the “dryer” antenna with a pidsiluvach on a high step is victorious. Obviously, without a pidsiluvach, you can’t catch anything.

We take the report information from fresh. Prinymnі vzhe already prompted, it means that the launch is coming soon!

Jump for a while. Frizi". However, judging by the picture, the order will be next to another multiplex, so soon everything will be wonderful.
