Tuning frequency of digital channels dvb t2. Buy a DVB-T2 digital set-top box from China

Installing a TV antenna, accessible to all TV viewers, allows you to get digital television in Moscow, broadcasting is carried out in the dvb-t2 standard. The analogue broadcast system is becoming a thing of the past and will be completely switched off in the near future. The reason for this is the improvement of radio frequency technologies. If previously no more than 18 programs were broadcast from the Ostankino tower, then in 2016 there are already 30. The channels operate digitally and are grouped in groups of 10 on one frequency, this package is called “Multiplex”.

1. First multiplex Ostankino TVK 30, frequency 546 MHz
2. Second multiplex Ostankino TVK 24, frequency 498 MHz
3. Test third multiplex Ostankino TVK 34, frequency 578 MHz

For local repeaters, broadcast parameters may differ. The Decree of the Government of the Russian Federation provides for the widespread launch of twenty federal, free channels. You will find towers under construction and operating in the Moscow region in the right block of the current page.

Advantages of terrestrial digital television

Maintenance free

Television installed in compliance with all rules serves long time without service maintenance.

Can be connected to one antenna a large number of TVs with serial cable wiring.

Digital quality

Image without interference and distortion with the DVB-T2 digital transmission system and high-definition support.

Without subscription fee

Free TV shows everything federal channels, 20 programs have been officially launched and 10 are in test mode.

Reception of digital television in Moscow is possible on any televisions, with the difference that for older models you will need a dvb-t2 receiver. This is a small set-top box with a separate remote control through which it is controlled. The signal from the antenna is supplied to the receiver, and you can connect it to the TV using a “tulips” or “scart” cord. How to set up the receiver is described in the user manual. In new types of flat TV panels, the tuner is already built-in, look for dvb-t2 in the specifications and try to find digital channels. If it doesn’t work, check the cable connection and find out if your house has a normal cable TV.

The main part of the equipment set is the antenna; the quality of terrestrial television reception depends on its power. For Moscow, an antenna with an average gain is usually sufficient. In some cases, a more powerful option is required. This happens when a country cottage, a private house or the cottage is located in a lowland and surrounded by tall trees. The distance to the tower also plays an important role. Installation is desirable in the highest part of the house; installation is carried out on a small bracket or steel mast. The price of the work will vary depending on the complexity; the exact cost is calculated by the master according to the standard price list, taking into account current discounts and promotions. The connection is made to the existing cabling using an amplifier and dividers. The master can arrive the very next day after receiving the order.

Broadcasting began at the end of 2013 digital signal standard DVB-T2, but there are still a lot of questions about how to set up digital television on a TV. Below are steps that will help you set up a digital tuner to receive signals and clarify some questions on this topic.

1. It is important how far you are from the transmitting station, i.e. are you in rural areas or city to receive free digital television.

2. In most cases it is necessary to have outdoor antenna with an amplifier, and in the city, in houses on the 4th or 5th floor, you can use a “mustache” or “frame” antenna without an amplifier with the signal amplification option on the TV set-top box turned on (and also not turned on).

3. Go to the digital television website http://rtrs.ru and determine the digital television coverage, signal broadcast frequency or its number, according to your region.

4. Through the TV set-top box, select Menu - Manual channel tuning - Select frequency (first or second multiplex) or air channel number (for example, frequency 594 MHz corresponds to channel 36) - Observe the signal level on the screen (adjust to the maximum value).

5. If the signal is not stable (constantly changes its level) and has less than 30% of the full signal, even if the channels show, there is a high probability of their interruption, broadcast stop or temporary absence of signal. In this case, it is necessary to: strengthen the signal, raise the antenna higher, move the antenna from the reception restricted area.

6. Enjoy watching!

How to choose a digital set-top box

Let me explain right away when choosing a digital set-top box, you should understand that Russian market there are now a large number.

Price for broadcast consoles DVB-T2 standard in stores starts from about 1000-1200 rubles, this includes the simple functionality of the set-top box, i.e. on the tuner:

NO control buttons,

NO display,

AVAILABLE additional codecs for playing audio and video content from USB media, In some

NO cords for connecting to a TV,

NOT the fastest processor in the line of tuners from this company, plastic case,

Maybe ABSENT HDMI and analogue TV output on TV,

EAT control panel and also + compact body.

In my opinion, such a set-top box is suitable for those who are ready to “cut down” on the points stated above, and you can purchase a set-top box and not lose the quality of signal reception.

Now about digital set-top boxes that can be bought from 1800-2700 rubles. The price range is large, but buy digital set-top box for 1800 rubles, or maybe cheaper, so to speak, in the maximum configuration it is real. I mean that the digital set-top box is equipped with:

• channel control buttons, menu, On/Off.
• display (shows channel number, time)
• Great support for video and audio codecs
• RCA cable, batteries, remote control
• HDMI input
• analogue TV output to TV
• compact, metal body

Owners of set-top boxes who watch video content via USB on the set-top box often encounter such a problem as there is a video image, but there is no sound, but this problem does not occur with all video files. Many people think that the console is faulty. But everything is much simpler, the digital set-top box does not have an audio format codec "AC3" aka "Dolby Digital". To avoid disappointment in the future, I recommend purchasing with this format.

Digital terrestrial television

The main difference between digital terrestrial channels and analogue ones is high quality digital channels(no noise, interference and repetitions) and a clearer picture - high noise immunity. I install antennas on the window in houses, on the side opposite the Ostankino Tower. The data transfer protocol is designed so that the reflected signal is received without unnecessary data and you see an excellent quality picture.

Digital television DVB-T2 is ideal for large LCD and plasma TVs.

The list of digital terrestrial television channels in Moscow now includes 20 channels.

HOW TO WATCH DIGITAL TERRESTRIAL CHANNELS?

To receive digital terrestrial channels in Moscow and the region, it is necessary that the TV has a built-in digital tuner DVB-T2 standard (see technical specifications of the TV). Otherwise, you will have to buy an additional DVB-T2 receiver, which connects to any TV via HDMI or composite (tulips or scart) input.

Digital reception ethereal channels carried out on external antenna UHF range. In your apartment building cable home network (Akado, OnLime, etc.), most likely these digital TV channels will be on other (cable) TV frequencies that do not coincide with the terrestrial frequencies given in the table. You need to start auto-search for channels.

If the distance from the transmitter (Ostankino TV tower in Moscow and Moscow region) to the TV is less than or about 20 km, then reception is possible with an indoor UHF antenna. Otherwise, you will have to use an external UHF antenna, possibly with an amplifier. It all depends on the installation height of your antenna and the distance to the TV tower. With a good outdoor UHF antenna with a low-noise amplifier, reception of digital terrestrial channels is possible at a distance of more than 80 km from the television tower.

The modern world can no longer be imagined without digital TV. This signal transmission has been used for quite some time to broadcast television and radio channels in many countries in Europe, America and Asia. In Russia, the process of transition from analogue to digital TV has been delayed.

The digital signal arriving through the receiver antenna allows you to watch more TV channels throughout the country without loss of quality or interference. In this case, the signal itself can arrive either to an antenna that is attached to set-top box, and directly to the TV. It all depends on how modern model of this device you have.

With devices that support DVB-T2, everything is simple. In order to connect to digital TV, just insert the cable into the appropriate connector and do a simple task. If your TV is outdated and does not support receiving this type of signal, then in order to view it you should purchase a special set-top box. It is inexpensive, but some people may have problems connecting and setting it up, so today we will talk about how to do this.

What is needed for this

To connect digital TV you will need:

• TV;
• Set-top box (receiver);
• Antenna.

Your TV should have an input into which you can insert an antenna, a tulip-type connector, and an input with video output (scart). If you have a scart connector together hdmi input, then no need to worry. It is also suitable for connecting a receiver. It's just that your model is newer.

Before buying a receiver, you should figure out which one is better and find out what parameters you should pay attention to in order to choose the most optimal model. If you don't understand much about technology, and spend your free time If you don’t want to study all these nuances, you can contact a company that provides television broadcasting services in your city and get advice from their specialists. In addition, you can take advantage of promotional offers from the service provider. Often, if you connect to their services, you can receive a receiver as a gift.

A receiver is essentially an adapter that allows you to receive and transmit a signal to your device. He can receive it through the following sources:

• Satellite dish;
• Antenna;
• Through the Internet;
• Using other sources.

Connecting a digital set-top box

To connect the receiver directly, you should follow these steps:

1. Take the TV box out of the box and remove it from protective film. It is necessary to remove the film. Otherwise, the receiver may overheat and break.
2. Take the TV cable and cut off the protective sheath, thus exposing 1-15 millimeters of the cable on both sides. The sheath should be stripped very carefully so as not to damage the shielding film, which is designed to protect the center conductor.
3. Carefully peel back the shiny protective film and screw the f-connectors to the wires.
4. Connect the TV to the set-top box using a cable.
5. Insert the wires into the tulip-type connectors on the TV and set-top box.
6. . The antenna itself should be installed on the external wall of the house or on your balcony, if it is not glazed. At the same time, make sure that it is not touched by tree branches or power cables.

This completes the process of connecting the TV set-top box. Next, to watch the TV channels available in your region, you should configure it.

In our country, many people still use televisions that were produced back in the Soviet years or in the early 90s. Connecting a receiver to such devices is not so easy - they do not have tulip-type connectors. Additionally, some models have scart outputs, but these only accept component signals.

These problems can be solved in two ways:

• Find a circuit for an adapter from the A/V input to scart and solder it yourself;
• Purchase a special adapter from the store to which you can attach an RCA cable from the set-top box or an adapter cable.

There are even more ancient models of TVs of the “Electron” type that do not provide any inputs at all, except for an antenna connector. A modulated signal enters the TV through this connector. high frequency, therefore, in order to watch digital TV on a device of this type, you will need to additionally purchase a modulator that will be equipped with RCA connectors.

Receiver setup

In order to set up digital channels on your TV, after connecting the set-top box to it, you will need to perform the following steps:

1. On the remote remote control press the "Menu" button.
2. In the window that opens, go to the settings menu.
3. You need to select Russia as the country if it is not the default.
4. Now you need to select the signal standard. By default, DTV-T/DTV-T2 is installed, that is, analog and digital TV, respectively. If you leave it this way, the TV will search for both channels.
5. You will be prompted to perform automatic or manual setup. Select Automatic and press the “OK” button on the remote control.
6. Now you need to wait a while until all available free and pay TV channels will be discovered. When you complete your search, click “Save.”

This is one of the most simple ways set up digital TV at home. If the TV finds few channels or does not find them at all, then you should use manual tuning.

To do this, you need to delete all the channels that were found for this. After the channels are deleted, you should repeat the same steps as for automatic search, but instead of auto-tuning select manual search. A window will appear in front of you in which you should set the frequency on which digital channels are broadcast in your city. You can find out this frequency on the Internet or by contacting your service provider. You may also need to change the search range for the search to begin.

After the TV channels of the first multiplex have been found, you will need to find out the frequency for the second multiplex in your city and start the manual search again. Thanks to this, you will be able to watch more channels.

Checking the signal quality

To make sure that you did everything correctly and everything is working well, you should check the quality of signal reception. This is not difficult to do. The receiver must have a button called INFO. By clicking on it three times, a window will appear on the screen with information about signal quality, channel number, frequency and encoding. If two existing indicators above 60%, it means everything is fine and the signal level is quite acceptable.

Perhaps in your model of TV set-top box this button will be called something else. To find out what this button is called for you, look at the instructions and read the purpose of the buttons.

If your TV receives several multiplexes, be sure to check the signal quality on each of them. This is due to the fact that each of them is transmitted and received using different transmitters, so it is quite possible that the signal will be good in one multiplex, but not in the second.

Hello friends! In this post I will continue the topic of how to set up DVB-T2. Terrestrial digital TV, 20 channels for free, how to set up an antenna and enjoy a high-quality image.

If you are interested in what types of digital television there are and how to choose the right TV given this variety, then follow this link and

You can ask about how to choose the right antenna for digital television

Well, right now, about how to set up the antenna and equipment for digital channels.

A little general information for a better understanding of the matter.

Currently, terrestrial digital television offers 20 television programs, and to listening to 3 radio stations. Total 23 and these channels are included in two digital television packages.

But what’s interesting is that the user does not need to separately configure all 23 frequency channels on his TV or set-top box, but only two.

P.S. Residents of Moscow and the region can enjoy more; they are broadcasting a third package, which already includes 30 digital television programs and the need to tune in three frequency channels.

To make it clearer, let's remember how it works in analog signal? In this case, one TV channel is broadcast on one frequency channel, for example, in my region, Channel One was broadcast on frequency channel 6, the Rossiya TV channel was broadcast on channel 12, and NTV broadcasts were broadcast on channel 27 in the UHF range. And then further - One frequency channel = one television channel!

With coming digital broadcasting everything has changed!

And one of its advantages is that now not one TV channel is broadcast on one frequency channel, but ten or more at once, so to speak in a package. This is called “Package” or “Multiplex”. For example, from the television center in Belgorod on channel 43 of digital broadcasting 10 television channels and plus 3 radio stations is the first package, and on the 46 channel frequency another 10 TV channels are the second package. Thus, only two television frequencies are used, and not twenty-three. But keep in mind that if in Belgorod these are channels 43 and 46, then in another city these will be different frequencies.

There is only one thing that unites everyone, in any region these will be frequencies of the decimeter (UHF) range, and therefore an antenna is also needed for UHF. (ADDITION: Currently, some broadcasters are still broadcasting only one of the two packages, i.e. only ten channels.)

Find out on which channels Digital Terrestrial Television is broadcast in your region, where the transmitting towers are located and whether they operate in full mode, broadcasting two packets, This information can be extremely useful for the successful installation of the antenna.

So, if you decide to organize digital terrestrial TV channels You will need:

1. A TV with a built-in DVB-T2 tuner or, if it does not have one, then you will need a set-top box for digital television, also in DVB-T2 format.
2. And of course the antenna itself, UHF range. Indoor or outdoor, depends on the proximity to the translator and the quality of the signal in your area.
3. Television cable, antenna plug.
4. Sometimes it helps to have a helper, and it never hurts to have patience and persistence.

How to find out if my TV is capable of receiving Digital Terrestrial Television

First, let's find out whether your TV is capable of receiving DVB-T2 signals without a set-top box, the fact is that not all devices are able to do this, old, non-flat TVs don’t even need to be checked, but flat LCD TVs may or may not receive . But if you know exactly what your TV is capable of, feel free to skip this part.

There are several ways: 1) (Dreary) Get the technical passport from the TV and look in the “technical specifications” section to find the presence of DVB-T2 there. Why is it boring? Look at your passport!….. Although sometimes you get lucky.

2) (Simpler) There is a tag on the TV case, on its back, with the TV model written on it, write it down or take a photo. Next you need to enter the TV model into search bar browser and add the word “Characteristics”. See examples in the photo below.

The model has been determined, we type in the search engine…….

Upon entering the site, select “ Specifications» then “Advanced” And we get where we need to be.

As you can see, this model is capable of receiving DVB-T2; it does not need a set-top box. Further designations indicate: C - digital cable, S2 - digital satellite. But we are interested in DVB-T2 and it is present, otherwise we would have to purchase an additional set-top box for digital television.

How to set up your antenna and TV for digital TV under different signal conditions

Let's look at the simplest option first: You live in the good zone confident reception signal. We have decided on the antenna, an article about this will help you. We connected the antenna to the TV and turned on auto channel search; in some models, when we go to the settings menu, the TV may prompt you to select and configure analog channels or digital choose digital. If everything went well, the TV itself will save the caught channels. You can admire the excellent image quality.

Let's complicate the situation a little. On auto-search, the TV did not catch anything, or only a few channels that were snowing. If this is so, then these are not digital channels, but ordinary analogue ones; digital television cannot go with the snow. (the fact is that on auto search, the TV can scan the entire range, both digital and analog).

Your next steps: If the auto search did not help, then It will greatly simplify the situation by knowing which TV channels broadcast the first and second multiplexes in your area. And also where and in what direction the TV tower is located from you in order to correctly point the antenna. If you don’t know this, then you can also see the desired direction of the antenna by paying attention to where the neighbors’ antennas are “looking.” Just don’t take it as a guide satellite dishes, they are sent to the satellite.

If you know the channel number, then do the following - You need to find the mode in the TV menu manual settings, do not forget to select “Digital”; it may be designated as DTV. Next, your task is to dial from the remote control the channel number on which one of the multiplexes (packages) is broadcast. IN manual mode a scale will be displayed on the screen that visually shows the signal level received by the antenna. (Sometimes there may be two scales, for example “Level” and “Quality”, refer to the bottom one)

And now, on the scale, you can see whether there is a signal from the antenna, in some cases, if there is no signal, then the indicator on the scale may behave like this: It will jump, zero percent - one hundred percent - zero - one hundred ..... etc. d. This indicates there is no signal. By changing the position and direction of the antenna, visually determine the best signal level, and this level should be stable, and if it changes, it should be within small limits, not to zero.

IMPORTANT: Please note that the result from changing the antenna position will not be reflected immediately, after about 5 seconds. So look best position stages, each time taking a short pause, observing the signal level on the scale. If the antenna is located on the street, then it will be more convenient to work here with an assistant.

When we managed to find the antenna position at which the signal is stable, we give the command to search and save channels. We repeat the search and save procedure for the second multiplex, indicating its channel number (if there is broadcasting of two multiplexes, it is not everywhere yet)

And now completely a difficult situation: You live in an area with difficult television reception. This may be due to the distance from the transmitting tower, the complexity of the terrain (mountains, lowlands, wooded areas). High-rise buildings located quite close to you and at the same time standing on the way to the transmitting tower, your antenna directed at the tower seems to “rest” against the high-rise.

In these cases, the principle of the adjustment itself is the same as described above; you need to visually determine the best position of the antenna using a scale. But the antennas used and some methods differ.

Antennas in difficult reception conditions must be used active ones, i.e. with an amplifier, also structurally having a higher gain. Typically, the longer the antenna arm, the greater its own gain.

Methods include the following: Determine if there are other transmission towers in a more favorable position for you. And try to catch a signal from them (fortunately they will be built quite tightly)

Using masts and other heights is the task of raising the antenna higher. (Effective in lowlands and wooded areas)

In built-up areas that are not very far from the tower, it is not necessary to use powerful antenna, try to catch the reflected signal, point the antenna not at the TV tower, but in the opposite direction, at the building behind you or on the side. If it is possible to install an antenna on the roof of a high-rise building, this will give excellent results.

Antenna setup via digital set-top box

When using a digital set-top box, everything is the same as described above; it is better to set it up manually in order to see the signal level. The only difference is that the TV plays the role of a monitor connected to the set-top box via hdmi cable or RCA (tulips). This means that all settings need to be made in the set-top box, and not in the TV. Just don’t forget to switch the TV to the appropriate VIDEO or HDMI mode (depending on what connectors you used for connection)

To do this, you need to find the corresponding button on the TV remote control, in different models it can be indicated in different ways, here are some examples, separated by an asterisk: AV* AV/TV*VIDEO* SOURSE * HDMI * RECTANGLE ICON WITH ARROW IN* INPUT* In some SONY TVs The order is as follows - HOME - Settings - External inputs.

All further actions settings are made using the remote control from the set-top box, through manual or automatic search.

Do not forget that in this case we connect the antenna to the set-top box, and not to the TV.

Read about what you need to know when choosing a digital set-top box.

Well, I hope this article can help you in connecting digital broadcasting to your home.

P.S. I decided to add them below to this article as interesting cases related to tuning antennas become available. If you have any, write them in the comments and they will definitely appear in your feed.

1. In my practice, very rarely, but there were cases when the antenna did not receive the signal at all, but as soon as I moved it literally a meter to the left or right, everything went fine, we returned it a meter back, again everything disappeared.
2. Today I encountered another incident. I'll describe it in detail. The situation is this: An old TV is standing on the floor, it works fine through the set-top box, indoor antenna located on the windowsill nearby, the signal level is about 70-80%. In this case, there is the following task.

You need to set up the number on the new LG LCD. I put it on the windowsill, next to the antenna that I connect to it, so what? LG does not see a signal at all, not even an ounce. Maybe it doesn’t support DVB-T2, I thought! I checked the model, no, everything is supported in order. What's wrong with the antenna? No, the old TV works through a set-top box. I'm at a loss!

I connect a set-top box to the new LG (What if!)........ There is a signal through the set-top box, but below 10% - It’s some kind of mystery why everything is fine with the old TV, but with the new one, which, even when in monitor mode, is connected through the set-top box, - television signal falls completely. 😯

After a short “Dancing around and around” It turned out!

The power supply of this LG was external and it was connected to the socket there, on the windowsill (there was an extension cord tee there). So, the OH power supply emitted such radio interference that being next to the antenna completely jammed the signal.

It was worth smashing into different sides, a few meters, the antenna and the power supply of the LCD TV, and everything immediately returned to normal. Bringing it close to the antenna again, the signal disappeared!

3. If you use an indoor antenna and your window is covered with metal blinds, then they can also seriously interfere with the signal. Keep this in mind!
