Connecting the DVB-T2 set-top box to modern and old TVs


I want to say right away that I am far from a specialist in satellite television. All I can boast of is the independent firmware of the Orton 4050c tuner 🙂

Not so long ago, I had to choose a TV. Opted for LG 32LN575U. Well, of course, as probably everything, read reviews, looked at online stores, and noticed in his description the presence of a digital tuner DVB-S2.

Googled a little, and realized that the presence of a digital tuner DVB-S2 allows you to directly connect a satellite dish to the TV, and watch satellite TV without a receiver. In simple terms, the DVB-S2 is a satellite tuner built into the TV. Since I have satellite TV, it became interesting to me.

A lot of LG TVs (and not only LG) are equipped with a DVB-S2 standard digital tuner. This can be seen in the description of a specific model. Here is an example description of the characteristics of the LG 32LN575U TV on the official website:

After the purchase, I certainly tested the operation of this digital satellite receiver, which is built into the TV. But, everything was not as rosy as you probably think. If you watch approximately 70-80 “of our” channels through a satellite receiver (for free), then simply connecting the plate to the TV, you can watch only fully open, not encoded channels. Among which, I did not find either Ukrainian or Russian (although I didn’t really look for it).

The thing is that the firmware of our satellite receivers has already introduced keys that allow you to watch encoded satellite channels. On the TV, these keys, of course, are not wired. And somehow leading them there, or changing the firmware, there is no possibility. Companies that produce these televisions do not need this at all.

You ask, why then in general this DVB-S2? To watch open channels that nobody needs? No, not at all. I think that all TVs that have a digital tuner of the DVB-S2 range support SAM modules. This is such a module into which a satellite pay-TV card is inserted, and which, in turn, is inserted into the TV, into the connector PCMCIAthat looks like this:

The scheme is as follows: You immediately connect a satellite dish to the TV, buy a starter pack of some kind of satellite television with a CAM module, and insert the card with the module into the PCMCIA connector of the TV. You start a channel search on the TV (on the satellites that your provider indicates to you), and watch the paid, closed channels that open using this very card from the provider, which is inserted into the PCMCIA connector of your TV.

This method has several significant advantages. For example, you do not need a receiver to watch satellite TV. And it turns out one remote control, you will control the channels from the remote control from the TV. It's comfortable.

If you will be connecting some kind of paid satellite TV, be sure to check with support if their SAM modules work on TVs with DVB-S2. And you can specify specifically on LG TVs, or by model.

As far as I know, for example, Lybid TV digital television satellites (Ukraine), works fine on LG TVs, without a separate tuner. I saw a promotion in some online store where the “Lybid TV” starter pack comes with LG TVs (it is with the CAM module, not the receiver). The module itself is called “EXSET CІ CAM“.

Configuring Satellite Channels (DVB-S2) on an LG TV

I did not connect pay-TV, and I do not have a CAM module to show the setting in such an example. But, I have a regular antenna for three satellites: Amos, Sirius and Hotbird. This whole thing works, of course, through a separate receiver.

But, I connected the satellite dish directly to the TV (recall, I tested on the LG 32LN575U TV). Started the search for channels on satellites. The TV found all the open channels, and showed it perfectly. Now I will show everything with an example. Maybe someone will come in handy, and it will be interesting.

Standard set-top box

  • user's manual,
  • RCA cable ("tulip") with characteristic connectors, allows you to connect consoles to almost all modern TV models,
  • a device for decrypting and converting a digital signal into an analog (receiver),
  • remote control (PU),
  • batteries for PU,
  • network adapter.

For different brands and different device models, the basic configuration may have different variations (for example, instead of a “tulip” there may be an HDMI cable), but in general the kit consists of just such elements.

There are connectors on the rear panel:

  • antenna input
  • connector for connecting a satellite dish, DMV antenna or cable of a local operator,
  • HDMI cable socket, designed to connect a monitor or TV,
  • jacks for the cable "tulip".

Some devices may optionally be equipped with a Scart connector, which connects a TV or DVD player with video recording function.

The process of connecting a DVB-T2 set-top box to a TV is in many ways similar to the procedure for connecting a satellite receiver or AV receiver. There are several different ways how to connect a t-2 console, how to connect a monitor to a console. Each of them depends on the type of connector, which are located on two paired devices. You can connect the tuner via an RCA cable (which is usually called simply a “tulip”), through an HDMI connector, through an antenna cable.

This is the easiest and most standard way to connect a digital tuner to a TV. The picture quality in this case is very different from the connection via HDMI, but the differences are not so significant on televisions with a large diagonal.

Before connecting, it is necessary to disconnect both devices from electricity. After that, insert the cable plugs into the sockets on the console. Each plug has its own color, so you need to insert them into the connectors of the corresponding color. A yellow signal is a video signal, white and red - 2 channels of audio. After that, the outdoor or indoor antenna is connected to the corresponding socket (on the console it is indicated as “RF IN”).

It happens that a set of wires does not include a “tulip”, but there is a “SCART” connector, which is popularly called a “comb”. In this case, you will need a special adapter from RCA to Scart. In the same way, you can connect a satellite receiver.

HDMI connector

The HDMI interface is capable of transmitting high quality signal. For example, the quality of the video signal can be up to 1080p, and the audio signal can be up to 192 kHz. It meets the highest standards in multimedia content.

If you have a modern TV, and it has an HDMI connector, it will be advisable to connect the receiver through this interface. The same can be recommended for a satellite tuner to watch high-definition television.

Channel setup

The number of channels depends on whether you will use a paid package of services of any one operator, or whether you will need normal broadcasting. About 20 free TV channels are available for regular TB. If this is not enough for you, then to view the encoded broadcasts, you will need to purchase a CAM module that is built into the receiver. A provider card is inserted into the CAM-module, which for a fee opens access to a large list of digital TV channels.

Setting: turn on the TV (if the prefix is ​​already connected), put the TV into "AV" mode, go to the tuner menu.

By default, the set-top box does not have a list of digital TB channels, so you will have to search for them yourself. To do this, it is recommended to use "Auto Search", which will independently find 10-20 channels. If the tuner can find them, he will offer to save the list. The whole setup algorithm is similar for different device models, but each has its own nuances.

Connecting the console to the TV

Before connecting the digital set-top box to the TV, you need to decide on the choice of the receiving device - the antenna.

Antennas come in many types and types. When choosing the right one, they are usually guided by several criteria, the main of which is the distance to the transmitting TB tower. The antenna can be either indoor or outdoor. For the DVB-T2 standard, the antenna should be in the decimeter range (UHF), namely, it should receive frequencies from 470 to 860 MHz. Indoor antenna will work well only in the city, in which there is a transmitting tower.

It happens that DVB-T2 does not find channels. This may occur for the following reasons:

  • the antenna does not receive digital terrestrial television signal (does not accept the UHF range),
  • hardware software is not relevant,
  • equipment does not support DVB-T standard

Most often, those people who try to connect through a house antenna are faced with a lack of signal. Here you can’t guess in advance whether such an antenna receives a signal in the UHF range or not. To do this, you need to call the company that services the antenna and specify. But it’s best to have your own antenna.

Connecting the console to old TVs

The method of connecting via an antenna cable is used in cases where there are no other connectors on the TV other than the antenna input (on older TVs). In this way, you can connect the tuner to the old TV by plugging the cable into the jack called “RF OUT”. In this case, the image quality will be much worse than when connected via HDMI. But given the fact that the TV is old, such an image can be considered quite acceptable.

To cable a digital TB to an old TV, you will need a piece of antenna wire of the appropriate length, as well as two antenna plugs. In order not to resort to the help of a soldering iron, you can use special F-connectors. To do this, clean the insulation from the antenna cable (very carefully so as not to damage the shielding braid). It is necessary to strip the end with a length of about 1.5 cm. After that, bend the braid, remove the insulating material from the central core. Strip 10 mm from the center wire. Screw the connectors clockwise until the central core protrudes 2 mm from the connector. Using the cable received, connect the antenna input of the TV to the corresponding output of the set-top box.

A TV with integrated satellite receiver has some advantages.

Corner of the story!

Yes, so I wrote in 2013. year! In a word, a few lyrical memories, or with what they worked not so long ago.

  • No need for a separate receiver.
  • No need HDMI-HDMI connection cable
  • No need for a separate remote control.

But you can forget about Aunt Shara, which is not a drawback for owners of official access cards.

But if the TV has a built-in digital tuner with support for the DVB-S2 standard, this means that the TV will receive (if the antenna is correctly tuned to the satellite) a satellite channel signal.
