How to select and connect a digital receiver for your TV

Televisions have become an integral part of the interior of any apartment, they create their own special, home atmosphere in the dwelling. With their help we entertain ourselves with long evenings, learn about the latest events in the world and relax together with the company of friends. And now, when there are LCD and plasma TVs, we can not just watch your favorite program, but enjoy it, thanks to the high-definition image.
However, not all "teleayaschiki" are able to please us with a clear picture. Even if you have a plasma or LCD device, you may need a receiver for the TV, without which you simply can not receive a digital signal. In this regard, it is quite obvious how to choose a receiver. To purchase did not disappoint you, you need to study all the nuances.

What is the receiver for?

Receiver is a multichannel amplifier with decoders of digital audio and video stream. Previously, when the most common were CRT TVs, the broadcast was analog - the information was transmitted from the nearest television tower. For such "teleallers" the signal quality was acceptable and sufficient to obtain a more or less high-quality image. Sense to improve the broadcast of audio and video stream using the receiver for the TV, was not, as to ensure better reproduction of the image was impossible. But today, with the advent of LCD and plasma TVs, everything has changed. Firstly, the diagonal of the screen increased, and the interference, those same gray-black bands that had previously been barely noticeable, seriously deteriorated the picture. Secondly, the information began to be represented in binary code - in figures 0 and 1. Hence the concept of "digital television". All this required the creation of a new technology for broadcasting - digital, which only the receiver is capable of perceiving.

How to choose a receiver?

Now the most popular and profitable is the digital receiver for TV of DVB-T2 format. In most modern "teletowners" already have built-in equipment of this type. Such models are marked with the appropriate logo - the abbreviation DVB-T2 on the device or on the box, or the image of a butterfly. In all other cases it is necessary to acquire additional equipment. When choosing a digital set-top box, the main thing is to indicate in its technical passport that it is receiving the DVB-T2 format, because there are several obsolete broadcasting technologies (DVB-C, DVB-T, DVB-S). In addition, make sure that the equipment supports MPEG-2 and MPEG-4 formats - the basic and progressive methods of presenting video information. These are the two most important nuances in which you need to make sure before buying.

Paid or free channels?

Today, television channels are divided into coded (available to the subscribed circle of persons) and free, for which any TV receiver is suitable. How to choose a prefix with support for paid channels? To do this, you need to make sure there is a card slot for a variety of encodings such as Viaccess, Conax, DRE Crypt and other providers. It must be remembered that a certain card gives access only to certain channels. If you plan to change the provider after some time and make other paid channels available for viewing, you should get a receiver equipped with a slot for the CI module. In this case, you do not have to change the prefix every time you subscribe to a new subscription. If you do not feel like paying money for watching closed TV channels, then purchase a digital receiver for a TV without such modules. The cost of such consoles is one or two thousand less.

Availability of interfaces

The presence of additional connectors, such as USB, E-sata, Sata or HDMI, allows you to significantly increase the functionality of the set you purchased. To determine whether you need more connectors, we suggest to study what they are used for:

• USB is used to connect flash cards, mobile phones and other devices via a USB cable directly to the receiver. As a rule, such consoles are able to play music, video and other files from your media.
• HDMI is used to connect the TV receiver to the TV to a laptop or PC, which will allow you to watch video without an intermediate link in the form of a flash card. In addition, this connector can be used to connect an additional screen to a computer.
• E-sata, Sata are required to connect a hard disk. A prefix with such an interface is advisable to buy when you plan to record TV broadcasts often.

In some cases, such interfaces are simply not necessary, for example, if you purchase an office receiver.

Additional Features

Some consoles can connect to the Internet. To get a similar digital TV-receiver for a TV is only if you are going to be engaged in card-sharing - gaining access to coded channels. In addition, that your "hacked" channel may stop broadcasting at any time, you may be subject to criminal prosecution. A common additional feature is video recording. Typically, such devices have a built-in USB or E-sata connector for connecting portable media.

Functional features

In addition to the remote control, the additional functions built into the receiver for the TV can be:

• Children's control - you will be able to block certain channels known only to you by a password.
• Delayed viewing - you will be able to "rewind" the broadcast to watch the transfer at another time.
• Pause mode - stop the broadcast and then continue it.
• TV Guide - you will receive a program schedule, as well as an announcement of any film and transfer.

Some devices can be equipped with a high-frequency modulator. This additional element in the set-up is used to view the same channels simultaneously on two TV sets.

Connecting the receiver to the antenna

There are a lot of ways to connect the console, and all thanks to a variety of connectors on the back of the device. They can also be used to connect the receiver for two TVs at the same time. But before that you need to connect the prefix itself to the antenna or satellite dish. Typically, this is done through a conventional television cable, in which there is a copper rod and a metal mesh.

This is done as follows:

• From the cable cut insulation with an indentation of 1-1.5 cm from the edge to completely release the copper rod.
• The metal mesh is bent and evenly distributed over the cable.
• To the prepared wire, fasten the f-nut.
• Connect the cable to the console.
• The reverse end of the cable is connected to the tuned antenna.

After that, you can assume that your receiver for the TV is ready for use. It remains only to connect it directly to the "teletowner".

Connecting a digital set-top box to a TV

To connect the receiver directly to the TV, you can use several methods. Most often, users resort to a SCART cable. Usually the set of wires goes in one box together with a prefix. The principle of combining devices is very simple - the plug is connected to the receiver, and the plugs are inserted into the connector on the TV. If both the receiver and the TV have an HDMI interface, they can be combined with the same cable. In this case, you must switch the TV box to the appropriate mode. Using both methods of connection simultaneously, you can use one receiver for 2 TV sets.

After the console is connected, you will see its interface on the screen. It is usually presented to users in the form of the inscription "No Signal". Do not be scared. If the antenna is tuned and you did everything correctly, then you only need to find the channels. To do this, go to the receiver's menu and select automatic search. After 5-10 minutes you can watch your favorite channels in digital format.
