A digital tuner is an important component, without which it is impossible to receive most modern channels. For the uninitiated, the choice of such a device becomes a big problem. Within the framework of this article, recommendations will be given regarding its choice, as well as connection and configuration. There really are many nuances that not everyone knows about, including the seller in the store.
Views
The digital tuner can be structurally presented in three versions:
- separate device;
- additional module installed in the TV receiver;
- expansion card for PC or laptop.
The first option is the most widespread so far. It allows you to set the DVB-T2 broadcasting standard not only on new TVs, but also on old ones that have SCART or tulip connectors. In the second case, this is a module installed in a special TV expansion slot. By default, most new devices are already equipped with them. But in order to open encrypted channels, you need this module. Not a very convenient solution that can beapply only on modern TV models. In the latter case, everything is clear anyway - you can watch the channels on a stationary PC or laptop. So far, this practice has not become widespread, and its prospects are rather vague. Therefore, the expression "digital tuner" today means a separate device for receiving an encoded signal, which stands next to the TV.
How to choose?
Before visiting the store, you need to study in detail the interfaces for connecting a TV. Now the most commonly used for switching such devices is a "tulip" (aka RCA). Less common is "SCART". Perhaps soon there will be models that will be equipped with "HDMI", but there are none yet. Well, since not every TV has the first type of socket, when choosing, you need to clarify what types of connections the digital tuner supports. It is important that its output and TV input are the same. The second important factor when choosing such a device is the equipment. It would be better if all the necessary wires are included in the assembly. The next point to consider is the presence of an information indicator on the front panel. In some cases, the information on it is irreplaceable. It is not recommended to buy immediately. It is better to study the reviews about it after the preliminary selection. If positive, then you can buy. But in the opposite case, it is better to continue the search.
Connection and setup
All digital tuners are connected as follows. One wire is power. It connects a 220 volt socket and a socketreceiver. The second is needed to connect the TV and tuner. It can be "SCART" or "tulip". A wire from the antenna is connected to a special socket. Next, you need to turn on the power switch on the back of its case. After that, the remote control gives a command to turn on. After downloading, you need to find the "Auto search" item in the menu and run it. The receiver will then start searching for channels. If its software version is not the latest, then all the latest updates will be downloaded via the digital broadcasting network. After completing all the above procedures, the receiver will turn on the first found channel. Then, by switching channels with the remote control, it will be possible to view everything that he found.
Conclusion
A digital TV tuner is an important component, without which it is impossible to imagine its work. The recommendations given for selection, connection and configuration will greatly simplify the launch of the device.
