Search for digital television channels dvb t2. Multiplexes of digital terrestrial television dvb-t2
The center for consulting support of the population on issues of connecting digital terrestrial television often receives questions from TV viewers about the timing of connecting the second multiplex in the southern regions of the Tyumen region.
The Ural-Siberian Regional Center draws the attention of television viewers to the fact that RTRS was forced to put a number of already built network facilities of the second multiplex into standby mode due to the request of broadcasters. At the initiative of the TV channels included in the second multiplex and the Ministry of Communications and Mass Communications of the Russian Federation, adjustments were made to the order of commissioning of broadcasting facilities of the RTRS-2 package of digital TV channels. It is expected that until 2018, RTRS will launch transmitters of the second multiplex in cities with a population of more than 50 thousand people. And after 2018, the remaining objects will be included. The decision to commission each transmitter of the second multiplex in a particular locality is made directly by the broadcasters, i.e. by the owners of TV channels that are part of the multiplex, and is only executed by RTRS branches.
The broadcast of the RTRS-2 package has been temporarily suspended at the following sites: Armizonskoye, Aromashevo, Berdyuzhye, Bunkovo, Vikulovo, Zavodoukovsk, Kolesnikovo, Malinovka, Novoberezovka, Shabanovo, Bolshoye Sorokino, Abatskoye, Vagai (Ulyanovka), Isetskoye, Kazanskoye, Krotovo, Nagorny, Nizhnyaya Tavda, Novoaleksandrovka, Sladkovo, Chernoe, Yurginskoye, Yalutorovsk, Yarkovo. Information about the resumption of broadcasting of the second multiplex will be communicated additionally.
The installation of a TV antenna, available to all TV viewers, allows you to receive 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”.
- First multiplex Ostankino TVK 30, frequency 546 MHz
- Second multiplex Ostankino TVK 24, frequency 498 MHz
- 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
A television installed in compliance with all rules will serve for a long time without service maintenance.
A large number of TVs can be connected to one antenna when the cable is laid in series.
Digital quality
Image without interference and distortion with the DVB-T2 digital transmission system and high-definition support.
No monthly fee
Free television shows all 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 you have regular cable TV in your home.

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, private house or 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.

First digital multiplex (RTRS-1)
The first digital multiplex or the first package of digital channels of the Russian Television and Radio Broadcasting Network (RTRS-1) is a package of all-Russian, publicly accessible and free television and radio resources for the population.
The list of all-Russian channels that should be available throughout the country was approved by the decree of the President of Russia “On all-Russian mandatory public television and radio channels” on June 24, 2009. The decree noted that the list of channels was compiled to preserve the general information space of Russia, as well as to provide citizens of the country with socially significant information. The law emphasizes that all radio and television channels on this list must be available to all Russians completely free of charge.
The State Commission on Radio Frequencies approved the frequency-territorial plan of RTRS-1 in 2009. Broadcasting of the digital package in Russia is carried out in the decimeter range from 470 to 862 MHz.
In 2012, the Russian government determined that the optimal broadcast standard for the RTRS-1 digital package is DVB-T2, the format is SDTV standard definition. It should be noted that before 2012, some regions had already been transferred to digital broadcasting, but in a different format. As a result, it was decided to transfer all subjects of Russia to one DVB-T2 standard.
The terrestrial digital package is broadcast free of charge and cannot be encrypted because the multiplex must be accessible to everyone.
For commercial or non-terrestrial broadcasting, the concept of RTRS-1 is not defined, but the law states that all operators are required, at their own expense, to broadcast public channels on their networks without making changes to them.
In Moscow, the first multiplex is broadcast on 30 TVCs at a frequency of 546 MHz in the DVB-T2 standard.

The second Russian digital television multiplex (RTRS-2)
The second digital multiplex or the second package of digital channels of the Russian Television and Radio Broadcasting Network (RTRS-2) is the next package of all-Russian, but not obligatory digital TV channels. The list of channels in the second package was compiled based on the results of a Roskomnadzor competition. If the TV resources of the first RTRS-1 are required to be distributed free of charge in all networks, then commercial operators decide on their own whether to distribute the second package for free.
In 2009, the State Commission on Radio Frequencies assigned the decimeter range from 470 to 862 MHz to the second digital TV package. Broadcasting is carried out by Federal State Unitary Enterprise RTRS, the standard is DVB-T2, the format is SDTV standard definition.
The second multiplex, like the first, is distributed free of charge and its signal is also not encrypted. All channels of the second package are known to subscribers of satellite, cable and IP television. The channels did not receive any special advantages when they were included in the RTRS-2 list, since these resources are not mandatory. In addition, analogue broadcasting of most of these resources is already present on the air in large cities. Operators provide subscribers with access to these channels in the cheapest subscription fee package or free of charge.
In Moscow, the second multiplex is broadcast on 24 TVCs at a frequency of 498 MHz in the DVB-T2 standard.

The third digital television multiplex in Russia
The third digital multiplex is just a planned package, which will include federal and regional TV channels. The decree on the formation of RTRS-3 was signed by the President of Russia in 2013.
Currently the Ministry of Communications and Mass Communications of the Russian Federation.
After the advent of digital television, many users wanted to switch to its reception. It's not just about frequent discussions and the desire to try something new. The signal quality is an order of magnitude higher, and ease of access increases attractiveness. It is possible to connect digital TV to both outdated CRT models using additional devices and to modern TVs.
Methods for receiving a digital signal
There are several ways to connect a high-quality signal to your TV:
- Cable TV. Reception is carried out via a common cable. The disadvantage is the subscription fee and not universal availability;
- Satellite television. The signal is transmitted via satellites, and received using an individual dish. A subscription fee plus the purchase of special equipment is also required;
- Terrestrial television. The digital TV signal is distributed from terrestrial repeaters and can be received from an indoor or outdoor antenna. This is a completely free method of watching TV shows in a modern format. It has disadvantages: the signal level is often low, the picture quality can be affected by the weather, the location of the tower, etc.
The least expensive method is to receive digital television through an antenna installed and configured by the user.
How digital television works
The transmission of pictures and sound for digital television is accomplished by encoding the video signal and sound over digital channels. Digital coding differs from analogue in its immunity to interference (external obstacles). Blurred, fuzzy picture, stripes are impossible here. The image is either clear or completely absent.
If the reception is uncertain, then perhaps the picture will disintegrate into squares, disappear from time to time and reappear. It depends on how you set up the antenna. Alternatively, you can install a different antenna or raise and deploy the existing one, pointing it at the TV tower.
Required equipment for viewing
- Antenna;
- A separate set-top box with a DVB T2 tuner that supports the MPEG 4 standard and can operate in Multiple PLP mode.
You can use a regular analog antenna. If the TV was released relatively recently, then it may have a built-in tuner of the required format (the outdated DVB T format is no longer supported). Then you don't need to buy anything else.
To find out whether there is a built-in DVB T2 tuner, you can look at the data in the data sheet. It’s even easier to find a TV model on the Internet and get a comprehensive answer.
Selecting a digital tuner
At first glance, all set-top boxes are the same. The main thing is not to make mistakes in the basic technical characteristics. But there are other features that affect the further operation of the equipment and the breadth of functions covered:
- The lack of buttons on the external panel of the set-top box will require you to use it only using the remote control, which is not always convenient;
- If the tuner does not have a USB port, this equipment cannot be used as a media player. If available, you can record TV shows and play back photos and videos.
Important! A good choice is a set-top box with a separate power supply. Usually it is built inside. The most common cause of tuner failure is a faulty power supply. If it breaks, you need to repair or replace the entire set-top box, and the remote power supply must be replaced separately without any problems.
Many people hang the TV on the wall, and quite high. Then it is inconvenient to use the usual design of the console. There are equipment modifications - compact set-top boxes that are attached to the back of the TV with tape. The strength of the fastening needs to be considered. Such a receiver is controlled by a remote control through a separate sensor attached to the same tape on the external panel of the TV. Power is supplied via a wire from the TV's USB port.
The set-top box can also be used in conjunction with a computer monitor (if there is an HDMI port). Then you can watch digital television from a regular antenna. If the built-in television tuner fails, it can be easily replaced using the receiver.
What channels are available for viewing?
To watch free digital channels through a regular antenna, the 2017 list contains two multiplexes:
- first RTRS 1 – frequency 546 MHz, channel 30;
- second RTRS 2 – frequency 498 MHz, channel 24.
Technical data is valid for Moscow and the region. They may differ in other regions. A total of twenty television channels and 3 more radio programs are available.
Important! The TV does not receive additional channels. Antenna settings will not affect the number of received channels, but only their quality.
How to locate a TV tower
Users living in the city, in the signal reception area from the TV tower, are not puzzled by such questions. But for residents of remote towns and villages, the information is relevant. What knowledge is needed for the best selection and correct configuration of the antenna:
- The exact location of the tower and the distance to it;
- Technical parameters (channels and broadcast frequencies), using which you can catch a digital signal in a given area. This is necessary so that the user can configure TV channels on the set-top box manually;
- Is the entire list of channels available for reception? There may be one or two packages.
Full information about TV towers is on the official RTRS website. There are maps where you need to enter the name of a specific locality in the search bar. A map of the given area will immediately open, on which all transmitting television towers are indicated (green - operating, black - under construction). If you click on the cursor hovered over the selected village, information will be available about where and how many kilometers away operating transmitters are installed, channel numbers (TVCs), broadcast frequency, number of packages).
The active menu includes a function, using which you can find out the coverage areas of individual repeaters.
Now, armed with knowledge, you need to determine whether it is enough to install an indoor antenna or whether you will need an outdoor, more powerful one.
Antenna types
The analog signal is received by the MV antenna. DVB antennas are more compact. There are combined samples capable of receiving both ranges. From such a combined design, you can remove unnecessary elements, and you will get an excellent UHF antenna. For example, if long whiskers (an element for the MV signal) are present, they can be removed.
All antennas are divided into:
- active;
- passive.
Active are those whose devices use amplifiers. The antenna with amplifier must be connected to a power source. If a receiver is used, 5-volt power for the amplifier is supplied through it. This is done in the menu settings. The option is called “Antenna Power”.
An amplifier does not always mean the best reception, in some cases its use can even be harmful:
- In an area near a TV tower, turning on the amplifier may lead to a complete loss of reception due to the signal being too strong;
- The amplifier is the weakest element of the antenna and often fails. Plus a power supply and additional wires, which also require repairs and replacements;
- The intensity of the TV signal itself is provided by the design of the antenna. And the amplifier simultaneously increases the level of noise and interference;
- If you want to connect another TV to a passive antenna, this is easier to do.
Passive designs do not have additional amplification and are usually used in areas with a stable signal.
Antenna selection and installation
An old antenna may be suitable for receiving a digital signal if it consists of short elements or a combination. If you have working, serviceable antennas, all that remains is to find out whether they will effectively catch “digital” in local conditions.
The UHF signal does not have a wide coverage area. Therefore, to distribute it, it is necessary to build a network of transmitters. The quality of the signal is greatly influenced by the surrounding landscape, the presence of high-rise buildings, mountains, forests, and the power of the repeater. Antenna installation must take into account all these factors.
Reliable reception area
The zone of a stable and reliable signal is considered to be an area within a radius of no more than 10 km from the television tower. Here, a simple indoor antenna will do an excellent job of reception. If you have an amplifier, you don't have to use it.
If the signal disappears, the image is torn, then you need to connect the existing amplifier through the set-top box by using the corresponding menu item. Power will be supplied via the antenna cable.
Multi-storey buildings can become a problem due to the reflection of decimeter waves. But this same reflection can be used. Let's say the antenna does not receive reception when it is oriented towards the TV tower. Direct it at nearby tall buildings; reception of the reflected signal may be much more effective.
It is necessary to check the presence of electrical appliances (third-party power supplies, etc.) near the indoor antenna, as well as metal blinds on the windows. They can significantly weaken the signal.
Short circuit
There are times when the set-top box suddenly stops responding to the use of the remote control or buttons, the image and sound disappear, and “Antenna short” is displayed on the screen. The problem does not mean that digital television is not working. There is simply a short circuit in the antenna cable or in the receiving device itself.
Why did the short circuit happen? There may be several reasons:
- The presence of a short circuit in the cable due to careless installation, most likely at the connection points. The antenna plug can only be damaged due to a manufacturing defect;
- The active receiving device is in operation, power is supplied to the amplifier. The amplifier is sensitive to lightning and can be damaged during bad weather;
- The passive antenna is connected, and the amplifier power is turned on in the receiver menu. Passive devices are often short-circuited.
In the latter case, you need to disconnect the receiver from the network, separate the antenna from it, then apply power again, on the connected tuner in the menu settings, set “Antenna power” to the “Off” position.
Important! Finding and eliminating the causes of the short circuit is carried out after separating the set-top box from the power supply.
Area remote from the TV tower
Far distance is considered to be more than 30 kilometers from the repeater. If there is a powerful transmitter and line of sight, we install a small receiving device such as a wave channel or log-periodic. You need to point the antenna at the TV tower. In such conditions, it is even possible to use a room device with an amplifier.
With increasing distance and when a populated area is located in low places, the requirements for the antenna increase. More powerful samples are needed. A good receiving device must include an amplifier, and its boom is long enough. There are examples with several arrows, but they will only be needed under extremely bad conditions.
Many users have the Polish antenna, as in the recent past it was popular due to its affordable cost. Another name for it is lattice. Can this design be adapted for digital television?
It is quite functional, but a number of changes are required. The antenna amplifier does not contribute, but interferes with signal reception. Therefore, he must be taken out of work. Simply unplugging the power supply is often ineffective. It is more reliable to remove the television cable from the amplifier board and connect it there to the two upper bolts: to one - the central core, to the other - the shielding braid. Thus, the amplifier is excluded from the circuit, and the antenna becomes passive.
Antenna and TV setup
There are several ways to properly configure a digital signal. The choice depends on the reception conditions.
Auto search
This method is the simplest, but it requires a strong, stable signal. The equipment is installed, turned on, digital channels are selected in the settings menu, and auto search is turned on. The TV automatically finds and stores the entire list of channels.
Manual mode
Let's say the TV cannot catch anything in auto search mode. Or channels with interference were found. These images are not digital. Perhaps the TV at the same time went through the entire frequency range and picked up several analog channels.
Now it will be useful to know the numbers of TV channels (TVCs) through which the signal is transmitted for each multiplex. Information about the location of the television broadcaster will also be useful for pointing the antenna in the right direction. If the house is surrounded by other residential buildings, you can navigate by neighboring receiving devices, but not by satellite dishes that “look” at their satellite.
- In the menu you need to enter manual settings by first selecting DTV (digital television);
- Enter the channel number or its frequency by dialing from the remote control;
- At the bottom of the menu, two indicators will appear showing the intensity of the television signal and its quality. Sometimes there is one indicator;
- If even a slight signal is present, you can begin to rotate and move the antenna to amplify it. You should not expect an instant reaction when changing the position of the receiving device. It will appear in a few seconds. The search must be carried out step by step, with pauses. When the antenna is external, it is difficult to do this alone; it is better to take an assistant;
- Immediately after the appearance of a stable signal with a good level, you can begin searching for channels and saving;
- The channels of the second multiplex are configured in the same way, if its reception is technically possible in the given area.
Important! If the signal disappears, then appears again with the scale filled to 100%, and so on one by one, this means there is no reception.
Complete lack of signal reception
This situation is typical for particularly unfavorable conditions, in low places, closed by mountains, near high-rise buildings, with low-power towers located far away.
Searching for a television signal must be done manually. At the same time, for its initial display on indicators, you need to show patience and endurance, having tried different methods:
- Purchase a powerful active antenna;
- If there are other towers nearby, you can sometimes try manual searching on a TV set to alternative repeaters. Perhaps the signal conditions will be better;
- Raising the antenna to a height using a mast gives a good effect;
- When the TV tower is located close, and the house is located in the center of a densely built-up area with high-rise buildings, you should not rush to buy an expensive, powerful receiving device. It is better to experiment with the reflected signal, alternately pointing the antenna in different directions at neighboring buildings or placing it on the roof.
Setup via receiver
Old TVs, models without built-in tuners with DVB T2 support, require configuration through the receiver.
CRT TVs are connected to a digital set-top box using tulip cables (RCA), LCD models are connected to an HDMI cable. In the first case, when setting up, the AV mode is selected, in the second - HDMI. The mode is selected from the television remote control. On remote controls, the mode selection is located under different buttons: INPUT, SOURCE, VIDEO, just a rectangle with an arrow.
Subsequent configuration is performed using auto search or manual using the add-on remote control. The antenna must be connected to the set-top box.
Receiving a digital television signal with a regular antenna is an easy way to ensure yourself viewing a high-quality picture, requiring minimal financial costs and physical effort. With the development of the network of television towers, signal reception conditions will improve.
