How to connect a digital set-top box dvb-t2 to a TV
The rapid development of technical progress in the field of broadcasting provides great opportunities for digital television for better reception of television programs compared to outdated - analog. But, to be able to watch digital TV broadcasts, receiver connection required (special set-top box for TV. Before, how to connect a digital set-top box to a tv, you need to decide on the choice of receiving device - antenna. so, to watch digital terrestrial television without any problems (CETV), necessary:
- antenna;
- receiver (prefix);
- channel tuning.
Antenna
The type of antenna is selected depending on the distance to the transmitting TV tower. Therefore, you should install a room antenna or outdoor. But, regardless of the type of location, it must operate in the decimeter range, namely - to receive frequencies from 470 to 860 MHz. Indoor antenna will work well within the city, where the transmission tower is located.
At a distance from the TV to the TV tower more, than 15 km, you need to use an external antenna.
The antenna for the dvb t2 set-top box can be bought in those outlets, where the tuners themselves are sold. In this case, high-quality TV reception is guaranteed, as the receiver is designed specifically for the digital tuner.
If you are going to install a TV set and set up CETV, then before, how to connect a set-top box, it is recommended to consult with neighbors first. They can tell, what type of antenna you prefer to choose for this area.
Also when choosing an antenna for suburban accommodation, you should ask about the presence of a built-in amplifier, without which, at a great distance from the transmitter, by connecting a digital TV set-top box to the TV, good image quality you will not achieve. If it is not possible to buy an antenna, then you can make it with your own hands.
Prefix (receiver)
As already mentioned, for, to be able to view CETV, you need to buy a set-top box, which is also called a tuner or dvb receiver. The electronics market has such a wide selection of such devices, that it is easy to get confused and overpay extra money for unnecessary features in the device. It is recommended to choose the tuner model based on your needs, since they all catch the TV signal, in principle, equally. There may be a difference, unless, installed additional options.
Example, if the set-top box will be used not only as a CET receiver, and also as a media player for watching videos from a flash drive, that's exactly the model you need to buy. But if you don't need it, buy a simpler model. In the picture, for example, model of inexpensive bbk receiver shown.
More expensive digital TV tuner models have Scheduler and TimeShift options on board. These features allow you to record any broadcast at a specified time, your presence is optional. All you have to do is set the start time of the recording on the desired channel, and time, when recording should stop.
Rostelecom consoles are currently gaining popularity., which have a modern filling: large amount of RAM and powerful processor. The tuner from Rostelecom is connected to the TV in the same way, as well as other similar devices. A special remote control is included, which can be configured to control as a set-top box, and the TV itself.
If you are going to buy a TV, then look in the specifications, it supports DVB-T2. In most models of modern TV tuner for watching CTV is already built-in, and you won't need to buy a set-top box.
Types of connections
Connecting a dvb t2 to a TV is little different from connecting a satellite receiver or av receiver. There are several methods, how to connect t2, and they depend on the types of connectors, located on two connected devices. The tuner can be connected via:
- RCA cable (in the people, the interface is called "Tulip");
- HDMI connector;
- antenna cable.
The figure shows the general scheme of connecting the tuner to the TV.
RCA cable
This is the easiest and standard way to do it, how to connect a digital tuner to a tv. Image quality, Of course, will be different from connecting via HDMI, but the difference will be invisible on TVs with small diagonals.
so, before, how to connect a cable, both devices must be de-energized. After de-energization, insert the cable plugs into the socket on the set-top box. Because each plug has its own color, then they are inserted into the connector of the corresponding color. The cable with the yellow plug receives a video signal, and in white and red - 2 audio channels. Then an external or indoor antenna is connected to the tuner in the appropriate jack (it is indicated on the prefix, як «RF IN»).
There are cases, when there is no Tulip interface in the TV, but there is a SCART connector, which is popularly called "Comb". The figure below shows, how does he look like (Samsung is taken as an example).
How to connect the receiver to the TV in this situation? In this case, you need to buy a special adapter from RCA to SCART. So, you can also connect a satellite receiver.
HDMI connector
HDMI interface is capable of transmitting high quality signal. Example, the quality of the transmitted signal can be up to 1080p, and audio signal - 192 kHz. These features meet the highest standards in the field of multimedia content.
If you have a modern TV, and it has an HDMI connector, it will be more correct to connect the receiver to the TV through this interface. The same recommendations apply to the satellite tuner, to watch TV in high definition.
Antenna cable
This type of connection is used, to connect a digital receiver, if on a TV, in addition to the antenna input, no more connectors are provided. Example, this way you can connect the tuner to an old TV, inserting the cable into the socket, called RF OUT.
Before, how to connect a digital t2 tuner to a tv, you will need to purchase a cable, shown in the figure below.
This method of connecting to the receiver cannot give a good picture, and compare it with the image, transmitted connects via HDMI interface - not worth it. But given that, as an old TV - the image can be considered acceptable for this situation.
Channel settings
After connecting the receiver to the TV, it's time to think, how to set up tv channels. Many users, when connecting the receiver to a TV, the question arises: how many channels you can watch, if you set up a digital tuner? In reality, it all depends, whether you will use a paid package of services of a certain provider, or terrestrial television will be enough for you. About 20 free TV channels are available for CETV. If you don't have enough of 20 TV programs, then you need to buy a CAM module to watch encoded broadcasts, which is inserted into the TV.
And the CAM-module is inserted into the card of your chosen CETV provider. With this schedule, you get access to a huge number of TV channels for a certain subscription fee.
so, for, to start setting up CETV, you should turn on the TV (the set-top box must be connected), switch it to AV mode and go to the tuner menu.
Because the default prefix does not contain a list of TV channels in its memory, then you have to find them yourself. It is recommended to use "Auto Search".
After a while you will see, that the receiver found from 10 to 20 TV channels.
When the search is complete, the tuner will offer to save the list of found broadcasts, then you can start watching CETV. The detailed configuration algorithm is similar in different manufacturers, however, there are some nuances to setting up Samsung and Philips TVs.
As you can see from the above recommendations, connecting and setting up digital television is not such a difficult task, to cope with which under the power of any owner of a TV set and DVB-T2 set-top box.
