Features of CETV
Digital terrestrial television( CETTV) enables the reception of Federal TV channels and radio stations included in the first and second multiplex in the MPEG-4 standard. Below you can find a list of these channels.
List of channels CETV
The peculiarity of this type of broadcasting is that you can watch the listed TV channels in high quality. As you know, the past generation of broadcasting - analogue terrestrial TV, is already outdated, as the broadcast picture has a low resolution, and on modern widescreen TVs the image is of very poor quality and blurry. The new format of broadcasting opens new facets, giving subscribers a high-quality clear picture and high-quality stereo sound.
CETTV broadcasts in principle, as well as the usual broadcasting of decimetric channels, only one channel includes 10 digital channels. Such channels are only 2, they represent the first and second multiplex. To process the signal, you need a special digital terrestrial receiver - a prefix.
Equipment
Let's take a closer look at the set of equipment, which is necessary for receiving digital terrestrial television channels of high definition.
Equipment required:
- Antenna;
- Receiver( tuner);
- Amplifier;
- Coaxial cable;
- Cable for connecting the receiver to the TV.
Antenna
To receive a CETV signal, you need a conventional decimetric antenna that receives channels at frequencies 470-860 MHz. Antennas can be of two types: home( room) or external. The type of antenna should be chosen relative to the distance from the TV tower( repeater).
The home antenna is suitable only when there is a TV tower in your city, at a distance of no more than 15 km from your house. In this case, you can do with an indoor antenna. If your distance to the TV tower exceeds 15 km, then you need to use an external antenna.
In the store of home appliances or radio electronics necessarily in the presence will be decimeter antennas for DVB-T2.Acquire special antennas, which are designed to receive a decimeter signal, they are designed according to all the rules of radiophysics and will provide a high-quality signal reception.
Talk to neighbors, surely some of them are watching CETV, find out which antenna they are using and what is the level and quality of the signal.
If in doubt, buy an external antenna.
Receiver( tuner)
The first thing to do is select the receiver. The receiver is a special prefix to the TV , as mentioned earlier, which processes the signal and sends it to the TV, the channels are tuned and switched through the receiver. To date, the market has a wide choice of receivers for receiving DVB-T2 channels.
Regarding the choice, they are almost identical and simple, choose the device based on the availability of additional functions: functionality and design of the menu, as well as the presence of connectors for connection to the TV.
In some modern TVs, from the middle and premium segments, there are models with built-in DVB-T2 tuner, thanks to which you will not need to buy a receiver, but simply connect the cable from the antenna to the corresponding jack and make channel tuning.
If you have satellite TV, some models of satellite receivers support the installation of CAM modules, including the DVB-T2 module. Thus, you only need to install the module in the receiver, connect the cable from the antenna to the second input jack, and you can watch digital terrestrial television channels along with satellite ones.
Amplifier
Most decimeter antennas( both indoor and outdoor) include a built-in amplifier, the signal from which is amplified by the receiver, which is enough for a confident reception if the type of antenna is selected correctly.
Let's consider the cases when you need a separate signal amplifier. With the DVB-T2 receiver, you can check the signal strength by entering the settings and displaying the corresponding scale. Connect the antenna to the receiver - if the signal level is around 75%, and the quality of the picture suits you, the amplifier is not needed. When the signal level is lower and the picture is noisy, it is recommended to install the amplifier.
Coaxial cable
This is a normal TV cable that transmits a signal from the antenna to the receiver. It is recommended to purchase a cable with a copper circuit and a screen, since it is of the highest quality, which will ensure a good signal transmission and a long service life of the cable. Pay attention to the braid of the cable, the stronger it is, the better, since the cable will be less prone to external influences: interference and destruction.
Cable for connecting the receiver to the TV
If the receiver you selected includes an HDMI connector that is also on the TV, it is better to use it for the connection, since this type of connection provides the best picture quality. To do this, you will need an HDMI cable, which you can buy at any store of household or computer equipment.
If there are no HDMI connectors, which is a bit bad, then use SCART connectors, RCA connectors and others.
Installation and setup of
First, install the antenna. The indoor antenna is usually installed on the window. An external antenna can be tried on the balcony or fixed near the window to the bracket, if you live in the side of the location of the TV tower. Route the cable from the antenna to the receiver. In the case where the signal is weak enough, or the TV tower is in the other side, then the antenna must be installed on the roof of the house. Point the antenna towards the TV tower, just look at the direction of the neighboring antennas.
Unpack the receiver, connect the cable to it from the antenna, then connect the cable from the TV.Then turn on the receiver to power, turn it on and make the initial settings: language, time and time zone, etc.
If the model supports automatic channel scanning, then you can use it. If there is no automatic search, then in the manual mode you need to select the necessary channels of the two multiplexes. In the regions, these channels may differ, most often channels 35 and 45.
Find the channel of the first multiplex and scan it, and then select the channel of the second multiplex and also scan it. The fact is that each of these channels has its own package of 10 channels. By the way, it is in this setup menu that the signal strength scale will be displayed. If the signal level is low - you can turn the antenna, picking the best direction, based on the scale.
Everything, now you can enjoy viewing the terrestrial digital television.
