Prefix dvb t2 what perfeo. Correct connection and setup of DVB-T2 set-top boxes. As a conclusion

The modern world can no longer be imagined without digital TV. Such signal transmission has been used for a long time for broadcasting TV and radio channels in many countries of Europe, America and Asia. In Russia, the process of transition from analog to digital TV has been delayed.

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

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 If your TV is outdated and does not support reception of this type of signal, then in order to watch digital channels, you should purchase a special set-top box.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

What is needed for this

To connect digital TV you need:

• TV set;
• Prefix (receiver);
• Antenna.

At the same time, your TV must have an input into which you can insert an antenna, a cinch connector, and an input with a video output (scart). If you have an hdmi input together with the scart connector, then don't 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 in technology, and you don't want to spend your free time studying 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 a service provider. Often, if you connect to their services, you can get a receiver as a gift.

A receiver, in fact, is 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

The receiver can be connected either directly to a TV, or via a DVD or monitor, however, for the latter two options, you will most likely need to purchase a special adapter.

In order to connect the receiver directly, you should follow these steps:

1. Take the TV box out of the box and remove the protective film from it. It is imperative to remove the film. Otherwise, the receiver may overheat and break.
2. Take a TV cable and cut off the protective sheath, thus exposing 1-15 millimeters of the cable on both sides. The sheath should be peeled off very carefully so as not to damage the shielding film that 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 cinch connectors on the TV and set-top box.
6. Connect the antenna to your TV. In this case, the antenna itself should be installed on the outer wall of the house or on your balcony, if it is not glazed. When doing this, make sure that no branches of trees or power wires touch it.

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 in the Soviet years or in the early 90s. It is not so easy to connect a receiver to such devices - they do not have tulip-type connectors. In addition, some models have scart outputs, but they only accept component signals.

There are two ways to solve these problems:

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

There are even more ancient models of TVs of the "Electron" type in which there are no inputs at all, except for the antenna connector. A modulated high-frequency signal is fed to the TV through this connector, so to watch digital TV on this type of device, you will need to additionally purchase a modulator that will be equipped with RCA connectors.

Setting up the receiver

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

1. Press the Menu button on the remote control.
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. The default is DTV-T / DTV-T2, that is, analog and digital TV, respectively. If left this way, the TV will search for both those and these channels.
5. You will be prompted for automatic or manual configuration. Select Automatic and press the "OK" button on the remote control.
6. Now you need to wait for a while until all available free and pay TV channels are found. After completing the search, click "Save".

This is one of the easiest ways to set up digital TV in your home. If the TV found few channels or did not find them at all, then you should use manual tuning.

To do this, you need to delete all channels that were found for this. After the channels have been deleted, 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 in order for the search to begin.

After the TV channels of the first multiplex are found, you will need to find out the frequency for the second multiplex in your city and start manual search again. This allows you to watch more channels.

Signal quality check

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

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

If your TV has multiple 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 very possible that in one multiplex the signal will be good, and in the second it will not.

Note.

A small overview of a miniature device for watching TV in digital format DVB-T2.

We already have TVs and a digital TV tuner at home, but we got a Perfeo PF-T2-1 receiver in the store at a very attractive price, only 600 rubles! Double intrigue - diminutiveness and price played a decisive role in choosing this device.
In principle, modern receivers (they are also tuners) have little functionality in terms of functionality. Standard outputs are tulips and HDMI. Scheduled recording, Timeshift, currently 2 operating multiplexes (20 TV channels and 3 radio).
The main differences between the devices of this rapidly growing army are the dimensions, convenience of the remote control and navigation buttons.
on the menu, as well as the speed of switching channels. The latest models increasingly support the AC3 codec, which is required to play sound in movies downloaded from the Internet. However, all tuners that I came across had raw software without the possibility of updating the firmware. In other words, to a greater or lesser extent, every tuner and TV has glitches, not working or malfunctioning functions.

Distinctive features of the Perfeo PF-T2-1 receiver

As already mentioned, the functionality of Perfeo PF-T2-1 standard. The main
the features are in the connectors and the connected wires:

• The wire with "tulips" is connected to the device using the plug included in the kit.
• The infrared receiver for operation with the remote control is not built into the case, but is connected separately.
• The receiver has an external power supply, and the 5-volt adapter is not included in the package.
• To connect a USB flash drive, you will also have to buy an adapter.

It is important to note that the so-called "OTG connector" has a non-standard format. Why this was done - God only knows. Take a look at the photo above. See the left connector labeled "USB"? You somehow need to connect a USB flash drive to it. You will not stick any flash drive and any fashionably called "OTG adapter" there. With the same success Perfeo engineers could solder some kind of RS-232 or LPT connector, which could not be implemented during the period of demand. The only way out is to buy separate connectors and solder the adapter yourself.

The power socket is round, if you do not plan to connect a USB flash drive, a 5 Volt 1 Ampere power supply will do. If you want to connect a USB flash drive, then you need a 5 Volt 2 Ampere unit. You can use mobile phone charging, since the adapter for connecting to the charger is included.

The external sensor of the IR remote control is attached with a double-sided Velcro strap in a place convenient for you. Also inside it there is a red-blue indicator that displays the operating mode of the receiver.

And now, all the wires are connected, the remote control is charged with batteries. Turn on autosearch of channels! The first channel was caught…. We are waiting ... Nothing changes on the screen for a long time, there is no reaction to the remote control either.
Blue screen - this is how the test of our Perfeo PF-T2 receiver ended. Neither re-switching nor dancing with a tambourine could bring him back to life. Out of curiosity, I took it apart, see what happened there ???

I think there is nothing more to write about - Perfeo has exceeded all expectations!

As a conclusion

… .. If the old basin were stronger, my story would be longer. (c)

Seriously, if you buy a 2-amp power supply and an ingenious "OTG" cable for a flash drive, there will be no gain at the price, but how long will the receiver itself last?

How to connect Perfeo PF-T2-1?

After writing the article, I was asked to explain how this receiver is connected. Indeed, the instructions for the device are rather meager, I did not come across the Perfeo PF-T2-1 connection diagram on the Internet, and I already handed over my copy. But I found a video (it is at the end of the article), where they show not ours, but a very similar model.

Video Notes:

1) At the beginning of the video, the USB connector (flat one, if anyone does not know) is stuck into the TV. I do not recommend doing this. More precisely, you can check the performance at the very beginning and in this way. Then I advise you to buy a charger. It looks something like this, the color and shape do not matter, the main thing is that there is such a rectangular connector as in the photo, and the current was 1.5 or 2 amperes. In extreme cases, you can also 1 amp.

2) "Tulips" (three multi-colored connectors) connect to the TV input. But old TVs may not have a red connector, then connect only white and yellow. If the TV has more than three tulip sockets, include in those with the inscription "INPUT" or "IN".

3) The infrared receiver (video time 1:45) of the Perfeo PF-T2-1 has a completely different connector - round and thin. It connects to the "IR IN" jack. Be sure to insert it all the way, you may need to press harder. If you don't insert it all the way, nothing will work!
The infrared receiver should face the dark red side towards us, and should not be tucked behind the TV. Any objects on the way to the remote control will interfere with channel switching and tuning.

After turning on the TV and receiver, press the "menu" button on the remote control and select the channel setting on the screen, usually this item is called "Automatic program search".

The video is not Perfeo PF-T2-1, but everything is connected in the same way.

Allowing to watch digital television. Digital TV has many more advantages than conventional TV, which is why many are switching to it. And, of course, you need to start by choosing a receiver. In this case, it is necessary to take into account the manufacturer's brand, functionality, quality and, of course, price. Finally, having purchased a digital receiver, you need to prepare it for use. But how to do that? In this article, you will learn how to connect and configure DVB-T2 digital television. Let's figure it out together.

If you want to know how to set up a TV box, then this article is for you.

The first step is to connect all the elements together. There is nothing difficult in this, see for yourself. Connect the antenna to the receiver and the receiver to the TV. That's it - you're done! Recommended connect the set-top box via HDMI cable , of course, provided that the devices have the appropriate inputs and connectors. If HDMI is not supported, please connect using regular tulips. With any model of the set-top box, there is an instruction in the kit, which clearly shows what and with what needs to be connected.

The functionality of the RF IN and Rf LOOP connectors should be noted separately. The cable coming from the TV antenna is connected to the “RF IN” connector, and “Rf LOOP” is the output of the signal received from the “RF IN” connector for its further transmission to other devices, that is, it can be called a replacement for “tees”.

Let's start connecting the device

Please note that the setup process is the same for all digital receiver models, so it doesn't matter which brand your set-top box is. Of course, the design of windows and some names of menu sections may differ slightly, but the general essence does not change.

First, the connection method is selected

After connecting the device, turn on the TV and set-top box. On the TV, you need to select the video input to go to the receiver menu. If everything was done correctly, then on the screen you will see a welcome window in which you will need to select the language, region, image mode and format, as well as the search mode. Set the required parameters using the console's remote control. You can leave the settings unchanged and leave them as default. Click "OK" to go to the next window.

The first dialog box on the screen

If “DVB-T + DVB-T2” is displayed in the “Search mode” section, then the receiver will immediately find all channels available for your region on its own. But this method will only work if you already have a working antenna pointing in the right direction. When auto search is finished, you can close the menu and enjoy watching. Other users need to position the antenna. There is nothing difficult in this, all that is needed is to make several settings in the receiver menu.

The list of available channels is loaded manually or automatically

In case you did not have an antenna before and it appeared only now, together with the DVB-T2 set-top box, being in the welcome window, press the button to call the menu on your remote control. Go to the “DVBT Setting” section and select “Channel Search”. In the window that opens, set the "Search mode". Here you can set both "by channel" and "by frequency". There is no big difference here - choose what you like best. Next, set the search bar "UHF".

To simplify the channel search process, visit a dedicated site with information on frequency channels for your specific city. In principle, this is not necessary, you can do without it, but this approach will facilitate and speed up the setup process. Select the desired value in the "Frequency channel" item. If the direction was chosen correctly, then after a couple of seconds you will see the filled scales "Signal intensity" and "Signal quality" at the bottom of the window. If the level of the scales is good, then click "Search". The receiver will then tune in the specified frequency channel.

In the event that you do not know the desired direction of the antenna, take it and smoothly rotate it, observing the intensity and quality scales. Once they are filled to an acceptable level, secure the antenna and search. Once tV channel tuning process is completed, you can exit the menu and start watching.

Most models provide the ability to simultaneously connect via both RCA and HDMI connectors

If you are connected via both Tulips and HDMI at the same time, you can switch from one cable to another while watching. It is better to look through HDMI, since in this case the image quality will be much higher.

Now you can easily perform DVB-T2 yourself. As you can see, it is not difficult to understand this issue. Write in the comments if this article helped you and ask questions if some points remain unclear.

There is no need to buy a new TV to take advantage of digital sound and picture quality both in the city and in the countryside - all DVB-T2 set-top boxes Perfeo you can even connect to the "old" analog! All models are equipped with a USB port, can work as a media player and record terrestrial TV programs in digital quality on external media (PVR function), and also support the "delayed viewing" mode (TimeShift function) - now you can simply press the "Pause" button, and then continue watching TV from the same place.

In models PF-168-1 and PF-168-3 there is a built-in media player with support for all popular video formats, as well as a codec AC3 when playing media files with Dolby Digital sound. Both models are available in two versions: with an internal or external power supply.

Series of similar capabilities compact DVB-T2 set-top boxes Perfeo consists of models PF-120-1, PF-120-2 (both on Novatek 78336 processor) and PF-120-3 (based on MStar 7T01 processor) equipped with external power supplies. At very attractive prices, compact set-top boxes lack support for the AC3 codec, which will not prevent you from enjoying your favorite TV shows with an MP3 audio track. Two models - PF-120-1 and PF-120-3 - provide wall mount holes.

Ultra-compact prefixes PF-T2-1 and PF-T2-2 use the MStar 7T01 processor and are not inferior in functionality to their larger brothers. The PF-T2-2 version is powered by a USB connector (if there is no one on the TV, you can use an optional USB adapter), and the overall dimensions of the PF-T2-1 are only 83 x 46 x 18 mm, which allows you to hide this set-top box behind the TV case, mounted on a wall mount.
