Useful Tips

Comrades tearfully ask you help advice on how to connect a digital tv set-top box


The state program for a phased transition to the digital broadcasting standard DVB T2 is approaching the final stage - a gradual reduction in the number of analog repeaters. This suggests that the time has come to get involved in new technologies and switch to the "digital". We will talk about the equipment necessary for receiving a television signal in a new format, as well as how to properly connect a digital set-top box (receiver) to a TV or monitor.

Necessary equipment

To watch digital broadcasting, unlike analog broadcasting, you need a receiver that decodes the signal. Many modern TV models (Philips, Samsung, Sony, Toshiba, LG, Panasonic, etc.) are equipped with such a unit. To verify this, refer to the user manual, this brief instruction is attached to each product. At the same time, check whether the built-in tuner supports the DVB-T2 format, if not, you will need to purchase a receiver.

Receiver Supra

Depending on the set of functional capabilities, the cost of such a device can vary between 800 - 3000 rubles. Note that many providers of digital cable television provide subscribers with receivers for rent.

In addition, we will need to receive a digital signal. In cities and large settlements with this problem will not arise, it is enough to contact local providers. Residents of rural areas will need to install a decimeter band antenna or satellite dish. The latter is preferable, since it is not a fact, your house is in the coverage area of ​​the nearest digital repeater. In addition, the satellite dish option provides a wider selection of television channels.

Standard set-top box

Consider what is included in the standard kit for the receiver, this information may be useful when it is connected to a television receiver.

Standard set-top box

We list what is shown in the figure:

  • A - user manual, we recommend that you carefully read this manual to get a complete picture of all the functionality of the device and its connection to the TV and antenna.
  • B - Tulip cable (RCA) with characteristic connectors, allows you to connect the console to almost all modern models of television receivers.
  • C is a device for decrypting and converting a digital signal into an analog (receiver).
  • D - packing box.
  • E - remote control for remote control of the device.
  • F - batteries for the remote control.
  • G - network adapter for connecting the device to a household electrical outlet.
  • H - warranty service coupon.

The basic equipment may slightly differ from that shown in the photo (for example, “Tulip” is replaced by an HDMI cable).

Connectors and their purpose

On the back of the device there are various connectors, briefly tell you what they are for.

Figure 3. SDT-96 receiver connectors from the SUPRA range

Explanation of the figure:

  1. Antenna Output
  2. A connector for connecting a satellite dish, a decimeter antenna, or a local provider's cable.
  3. A jack for an HDMI cable allows you to connect a monitor or TV equipped with this input (digital output can transmit sound and image).
  4. Sockets for the Tulip cable (transmits an analog video signal, as well as stereo sound).

Some devices can be additionally equipped with a SCART connector, a TV, VCR or DVD player with video recording function is connected to it.

Receiver with SCART connector

In addition, there may be devices where instead of an HDMI jack, D-SUB or DVI outputs are installed.

Please note that such interfaces do not transmit sound, so an additional connection with the help of "tulips" will be required to transmit it.

The process of connecting a digital set-top box to a new TV is step by step

Important! All manipulations must be done with the equipment turned off. If you connect working equipment, there is a high probability of its failure.

We will describe the order of our actions:

  1. You must select the interface for connecting the console to the TV. It can be analog (tulips, D-SUB, SCART) or digital (HDMI, DVI). The choice is made depending on the specific TV model. Despite the fact that many FULL HD class television receivers have an analog input, it is better to feed them a “digit”, since double signal conversion will negatively affect the quality of the “picture”.
HDMI input on TV

This interface allows you to transmit video and sound, so the connection can be made with a single cable.

If the TV does not have a digital input, it is connected by any analog interface, the easiest way to do this is with tulips. In the case when the device has only a bulky SCART connector, you can purchase an adapter for the tulip for it. In this way, you can connect almost any model, except for very ancient ones.

  1. We check the availability of the cable necessary for connecting, it can go bundled with the receiver or television receiver. If you could not find one, you will need to purchase it.
  2. We remove the protective film from the set-top box (if any), install it in the chosen place and connect it to the TV. The cables are made in such a way that it is physically impossible to insert them into the connector not intended for this purpose. The exception is tulips, they can be confused. But, to prevent this, manufacturers make nests for them in the corresponding color.
Standard colors for RCA connectors (tulips)

As you can see, the colors of the connectors coincide with the colors of the sockets (4 in Fig. 3).

  1. We connect power to the console. If the power adapter is built-in, we simply plug the plug into a power outlet, and we pre-connect the external power supply to the corresponding socket on the receiver.
  2. We connect the provider's cable, decimeter antenna or satellite dish to the antenna input (2 Fig. 3).
  3. We insert the batteries into the remote control, turn on the console and the TV.

This completes the connection procedure, and you can begin to configure the channels. If your TV does not have the above interfaces, do not worry, we will tell you how to get out of this situation.

Connection via RCA cable

RCA sockets were equipped with televisions to work in tandem with video consoles, VCRs and video players.

Before you begin, you must turn off the power of the TV and set-top box. After that, we insert the wires into the sockets located on the back of the receiver one by one. Each wire has its own color marking, so at this stage there should not be any difficulties. White and red wires are responsible for the left and right channel of the audio signal, yellow (for video) is also connected to the corresponding color socket.

Next, you need to make the same connection for the TV and connect an external or indoor antenna to the console.

At the next stage, turn on the power and configure the TV channels. To do this, select “AV input” in the TV menu.

Connection via antenna (coaxial) cable

This type of connection is more suitable for very old TV models that do not have a video input. In this case, the prefix is ​​connected via a standard antenna cable. To do this, turn off the power and connect the antenna to the console. After that, you can configure the channels.

Important! Not all consoles have the necessary antenna output, so consider this point when buying a receiver.

It is worth noting that this method is not the best, because when connected through a simple antenna you will not get the desired image and sound quality.

Channel setup

To view the standard free TV package included in the first and second multiplexes (10 channels each), you can configure it immediately after installing and connecting the set-top box. If you plan to view an extended list of channels that are broadcast in encoded form, you will need additional equipment to decode them. You will have to buy a CAM module and a special decoding card. In addition, a fee for the selected channel package should be paid to the card balance.

If you need 20 channels of free digital broadcasting, then after connecting the receiver and cable, you must scan them. Most models of TVs and set-top boxes carry out this function in automatic mode, in some it must be done manually. In any case, there should not be any difficulties. In the TV menu, select manual scanning and run it, at the end you will see all the channels included in both multiplexes.

If you decide to use the extended list of channels, for example, from NTV + or any other provider, you will first have to purchase a CAM module and a card. It must be placed in the conditional access module and then in the CAM device, which is inserted into the TV itself. After that, you can turn on the TV and scan channels manually or automatically.

The cost of additional equipment depends on the selected service provider. Some providers provide an extremely complete package of equipment, which means that it will not be possible to buy only a CAM-module and an additional access card. The standard set includes a prefix module and a card, the cost of which can be in the range from 4000 to 9000 rubles. Some providers provide equipment for rent, in which case the cost will be much less.

Advice! For the best video playback, it is best to set the frequency to 114,000 kHz.

Connection without a prefix

If your TV is equipped with a built-in tuner DVB-T2, then there is no need to buy a set-top box. To connect such a TV, only a decimeter antenna will be enough, which can be immediately connected to the antenna input and start scanning digital channels. In addition, control in this case will be carried out from one remote control, which is much more convenient.

Goldstar PD-10A12

Comrades, I tearfully ask you to help me with advice on how to connect the digital TV set-top box D2 to the PD-10A 12. The outputs are available on the set-top box D2 and on a portable DVD-player in the photo.

Sincerely, Vasily.

Unfortunately, I have already tried several wires (sinned on a faulty wire). Therefore, it was more desperate for me to stick it in AV, and in the dividend in AV IN. The signal does not pass. The digital prefix is ​​100% working, I checked it on the TV using the tulip inputs on the TV. Is it possible to connect - in a digital set-top box with ashdimiai output, and in DVD in AV IN? Are there such adapters in nature, or can you tell me how to solder?

Connect to an old TV

The signal converter can work even with old models of television receivers when connecting them to the antenna output (1 in Fig. 3). To do this, you need a piece of antenna wire of the appropriate length and two antenna plugs. In order not to trouble yourself with soldering, you can take special F-connectors, the procedure for mounting them on a cable is shown in Figure 8.

Installation on the cable F-plug


  1. Remove the insulation from the antenna cable, carefully so as not to damage the braid (just clean 15 mm).
  2. We bend the braid, as shown in the picture.
  3. Carefully remove the insulation from the central core.
  4. It is necessary to expose 10 mm of the central wire.
  5. Screw the connector clockwise.
  6. We do this until the central core protrudes 2 mm from the connector.

Using the cable made, we connect the antenna input of the TV to the corresponding output of the console. In this way, you can connect any TV, whether it be Horizon 101 or the legendary KVN.

How to connect 2 TVs to a digital set-top box

Two television receivers can be connected via the antenna output, for this you need a special adapter with one to two cables (splitter).

Double splitter

Since the set-top box is intended for only one device, two televisions will work simultaneously, that is, show the same channel.

The set-top box is configured in the same way as a TV, namely:

  • The menu is called up using the button of the same name on the remote control.
  • Select the appropriate command that starts the channel scan.
  • When the scan is finished, we save the list of detected channels, if desired, they can be grouped in a certain way, give a name, etc.

Detailed instructions and a description of the functionality can be found in the user manual. In most cases, the menu interface is intuitive, so setting up the receiver is as simple as connecting a digital set-top box to the TV.
