How to set up terrestrial TV on your digital TV

In order to view terrestrial TV without connecting a receiver, you must have a tuner inside the TV. It is easier to tune the channels when using an external antenna. This is due to the fact that in many regions the signal level will be low. At a great distance from the source automatic search or manual mode will not bring the proper result. The coverage area of most transmitters is only 30 km. Large objects reduce this value.

Tuning digital TV channels without a set-top box

You can tune any TV to receive terrestrial broadcasts by yourself. To do this:

  • Install the external antenna so that the signal is not in the way of large objects or trees;
  • Open the TV settings and select automatic channel search.

In most cases, the TV itself assigns a channel number after finding the channels. If the signal is weak, the device will skip it. You can add channels with an average level of reception in manual mode.

What is DVB-S/S2, DVB-T/T2, DVB-C?

Choosing a satellite or terrestrial receiver, many customers paid attention to the presence of one or more logos DVB-T, DVB-T2, DVB-C, DVB-S, DVB-S2, or for some receivers even DVB-S2X on the front panel of the device or on the package.

Most people don’t think about the meaning of such markings, assuming that it’s just another marketing trick by the manufacturer, wrapped up in a beautiful logo of additional functionality, affecting the quality of picture or sound, which is never useful. Those who are more attentive to the choice of digital receivers, quickly understand that the prefix DVB stands for Digital Video Broadcasting and indicates that the device belongs to the class of digital television receivers.

What is digital TV?? How it differs from analog television? Is it worth the extra cost?? These questions we often get from buyers, we’ll try to explain a little.

As stated by Wikipedia digital television is a modern technology for encoding video and audio signals using MPEG compression standards, used to transmit television picture and sound. And the term DVB (Digital Video Broadcasting) refers to the family of digital television standards developed by the international consortium DVB Project. Initially, the signal in this form was broadcast only from a satellite, so the first standard appeared DVB-S, where S is the first letter of the word Satellite, indicating ownership of satellite television. Over time, digital television, due to much better picture and sound quality and greater functionality, has supplanted analog television not only on satellite, but also on the airwaves and cable networks. All of the above mentioned channels to deliver content to viewers had different frequency channels, modulation, etc.п., so they were labelled differently:

  • DVB-S, indicates satellite TV;
  • DVB-T, indicates that it belongs to terrestrial TV;
  • DVB-C, indicates cable TV.

As mentioned above digital television has several advantages over analog. In addition to better picture and sound quality, it is possible to get both HD and 4K UltraHD picture and surround sound. Various auxiliary information is also added to the stream, such as several audio tracks, EPG TV guide, etc.д.


DVB-S and DVB-S2 are two generations of digital satellite TV broadcasting, DVB-S appeared in mid 90s of last century and DVB-S2 was developed in 2003 and finally approved in 2005. The presence of such logos on a receiver or TV indicates the ability to receive satellite TV.

It is generally believed that if your satellite receiver has the DVB-S2 logo, then such a device belongs to the HD receivers (HDTV tuner). This is true for household satellite tuners, but not always for professional equipment.

The mere presence of such a logo, of course, does not guarantee signal reception from the satellite, you must additionally install a satellite dish, tune it to the desired satellite, if the signal is encoded, then perform its decoding. You can read about it in detail in the article Self-installation and adjustment of the satellite dish.

Most modern satellite tuners are already equipped to support DVB-S2 standard modification. DVB-S2X. This modification is an extension of the DVB-S2 standard, aimed at improving performance and adding new features. DVB-S2X appeared due to new broadcasting requirements that appeared more than 10 years after DVB-S2 was released.

The modern DVB-S2X modification is characterized by improved spectral efficiency of signal-to-noise ratio (C/N), with support for low C/N values, up to.10 dB for mobile applications.


DVB-T and DVB-T2. two generations of over-the-air digital TV standards. In Ukraine the on-air television massively changes from analog to digital just in DVB-T2, because it is modern, more functional than DVB-T.

DVB-T2 logo on the receiver or TV set will indicate that the given device is capable to receive digital terrestrial TV signal. But, as in the case of the satellite, the receiver itself is not enough, you need to select and configure the right aerial, for this with the article Selecting the aerial for terrestrial television.


With DVB-C and DVB-C2 the situation is slightly different. The former is actively used by cable operators and if you are connected to digital cable TV, your TV or receiver supports DVB-C. All modern televisions support DVB-C, and if you have a TV from previous generations, you’ll need a DVB-C cable tuner to receive a digital signal.

Many providers encode cable signal, so you need conditional access cards for decoding. To work with these cards, cable tuners are equipped with a card reader or have a slot for a CI Conditional Access Module. TVs usually support CI module.

Main difference between DVB-C2 and DVB-C is using in second generation standard OFDM instead of one QAM-modulated carrier. DVB-C2 exists more on paper, it has not found mass practical application in home networks.

If several logos are present at the same time, for example DVB-S/S2, DVB-T/T2 and DVB-C on the TV set or receiver it indicates several tuners for receiving signals from different sources. If the receiver has several different tuners, it is called a combined or hybrid. Such devices allow the owner to receive a signal with all available channels, and, given that modern receivers are capable of connecting to the Internet, it adds the ability to access IP-TV. In this case the number of channels can easily exceed 1000, and it can be not only public channels but also niche channels. sports, scientific, educational, movie, adult.

Is it necessary to buy, when and who needs to do it?

The main criterion for which people buy an external tuner is the lack of a built-in receiver. Sometimes your TV set has an older-generation tuner that can’t work with modern digital formats. In this case, buying a set-top box is a justified decision.

Receiver is required for those users who want to access a large number of channels in good quality. You will need, at a minimum, a TV with a high resolution screen.

Also, the tuner will be of no use if you live in a remote area where there is virtually no over-the-air signal, no cable TV, and no way to install a satellite dish.

Beginning in 2019, analog terrestrial broadcasting will be switched to a digital standard. This does not mean that the analog signal will disappear completely. Just the state will stop subsidizing the main federal channels. Some have already confirmed that they will independently provide an analog signal to their viewers. Full transition to digital broadcasting is planned for 2021.

Do you need a set-top box if you have cable TV

When considering the problem of buying and installing a device that receives digital TV on “older” models of TV receivers, users often ask, “Is a digital set-top box necessary and how to connect it to an “ancient” TV?” Let’s try to understand the problem.

Features of cable TV

In order to clarify this question, it is first necessary to understand how this kind of transmission reception is done. This method of broadcasting is gradually planned to replace analogue television, which has been a pain in the ass with constant interference on TV screens. How it differs from its predecessor?

First, this broadcasting system transmits television signals in a closed form. Secondly, it is broadcast via fiber-optic channels. As a result, the TV signal is much more resistant to interference than analog TV. Currently cable TV has two broadcast formats. DVB-C or DVB-C2. first and second generation (with more TV channels).

In the early days of cable TV, signal transmission was carried out in the image and likeness of analog TV. An antenna cable connected to the antenna socket on the TV was connected to the panelboard, which, when connecting several apartments of the riser instead of the central antenna located on the roof, was lowered and connected to a special amplifier in the basement. As a result, poorly shielded from the environment signal was perceived by TV receivers with a lot of interference, which was very bad for watching your favorite TV programs.

That’s why telecom specialists first started supplementing analog signal transmission and then gradually replacing it with digital technology.

Why you don’t need a set-top box to watch cable TV

In a cable system, the signal is received from satellites by special equipment in the transmitting center, and then is transmitted to fiber-optic and cable channels equipped with repeaters and amplifiers. The subscriber’s TV set already had a TV tuner for decoding, converting and transmitting the signal to the receiver.

If over-the-air television becomes digital, it won’t have any effect on the cable broadcasting system. A set-top box (DVB-T2) is only needed for those who don’t use cable TV.

It should be recalled that if the user is planning to refuse the services of cable dealers, he can not do without an additional set-top box (DVB-T2) to enjoy watching “digital”.

What happens when you switch from cable to digital TV

Whether to save the subscription? Or leave it as is? It’s up to the subscriber to make this decision. To make the best choice for you.

To make a decision about switching from cable TV to digital terrestrial broadcasting, you need to consider the following nuances:
