When the switch to digital broadcasting happened in 2009, many people probably wondered about what is a digital tuner for TV. However, to understand what it is, you have to understand what digital TV is and why it became some of the top-rated TVs. Additionally, it can be helpful to know whether a TV has a digital tuner.
- Digital tuners allow the TV to receive digital television signals broadcast over the air.
- TVs often include labels that indicate whether a digital tuner is present.
- Many digital tuners still require an antenna to be used.
What Does a Digital TV Tuner Do?
Because of this, many TV manufacturers exclusively make a digital tuner that enables the TV to receive television broadcast over-the-air by local stations in the digital television format. You should now know what a digital TV is and if your TV is one. As of June 12, 2009, the Federal Communications Commission (FCC) requires all full-power broadcast stations to transmit their content digitally. You can read our article about when TV went digital to learn more about this. In addition, as of July 13, 2021, low-power broadcast stations now must follow digital TVs (DTVs.) Many channels can be watched using a TV with a digital tuner and an antenna. Additionally, these DTVs can be used with a streaming device, such as a Roku or Amazon Fire Stick. Furthermore, set-top boxes that connect to streaming services should also work with a digital TV. Finally, all smart TVs are capable of processing digital signals. However, digital TVs do not always have digital tuners. If you do not have a smart TV but want the functionality of one, you can check out the LG Smart TV Upgrader.
How Do I Know If My TV Has a Digital Tuner?
If you purchased your TV after March 2007, it’s likely that it contains a built-in digital tuner; however, because some stores sold older TVs from existing inventory after that date, it’s not a guarantee. However, there are some additional ways you can determine whether your TV has a digital tuner.
When you buy a TV, some labels indicate that the TV has a digital tuner. Owners may find these labels on their TV or in the owner’s manual. These labels include:
- Integrated digital tuner.
- Digital receiver.
- Digital tuner.
If the TV displays specific labels, the TV does not have a digital tuner. These TVs would need an additional digital converter and antenna to receive the broadcasts from local channels. Retailers also sell external digital tuners that can be used with an antenna and TVs that do not have an internal one. Some of these external tuners have an antenna included, but make sure this is the case for the one you are looking at if you do not have an antenna. These indicators include:
- Digital monitor.
- HDTV monitor.
- HDTV ready.
What Requires a Digital TV Tuner?
Viewers wishing to watch over-the-air broadcast channels need a digital TV tuner, as well as an antenna, to receive the signal. However, many local stations broadcast over the air, and owners with an indoor or outdoor antenna can tune in to these stations for free. However, many cable or satellite services include these channels in their subscriptions. The FCC has an option for searching by location for digital signals broadcast over the air. Channels sometimes change their frequency, requiring users to rescan for the signal.
Digital TV tuners interpret the digital signals received by an antenna. So, TV users who want to watch digital over-the-air broadcasts require a built-in tuner, external tuner, or converter box, as well as an antenna. The user also may need to connect their antenna with the device that distinguishes channels to use these items. For some external scanners, users simply plug them into the USB port because they include an antenna. An additional antenna is unnecessary if you have cable or satellite since these stations are typically available through your service provider. It should be noted, however, that this may cause your TV to appear fuzzy, and you can learn more about why this is in our article on why is my TV fuzzy. You may not need a digital TV tuner if you know what a smart TV is and you have one.
How do I use my digital tuner with my TV?
To use the digital tuner, you will need an antenna that can receive digital signals. Furthermore, you will need a coax cable to connect the antenna and your TV or the antenna and the external digital tuner or converter box.
Do I need an antenna if my TV has a built-in digital tuner?
Yes, because the TV still needs something to receive the over-the-air signal. If you do not want to watch local over-the-air channels and only want to stream or watch something using a different device, you do not need an antenna.
Do smart TVs have built-in digital antennas?
Many smart TVs have digital tuners, but they do not have antennas. TospecificIn order to watch over-the-air TV, you will need an antenna.
STAT: If you purchased your TV after March 2007, it’s likely that it contains a built-in digital tuner; however, because some stores sold older TVs from existing inventory after that date, it’s not a guarantee. (source)

Varieties of TV tuners
Only digital TV tuner can be found in stores, because analog types have gone out of use, and before they were designated by NTSC, PAL, SECAM formats. Set-top boxes differ in terms of broadcast standard, type of connection to a TV or computer, and operating system support.
Digital tuner receives TV signal and decodes it depending on broadcast standards, including:
- is an obsolete digital terrestrial broadcast format that is not used today;
- – on-air digital broadcasting, an improved version of the previous format. The bandwidth is increased, as is the resistance to interference, which allows you to transfer the image to the screens in HD quality;
- DVB-C – digital cable TV reception. The format is more common in the CIS, Asia and Europe;
- DVB-S – satellite digital broadcasting;
- DVB-S2 is an improved version of the previous broadcast with more bandwidth and resistance to interference.
By type of outlets
The equipment differs by the type of connection. In stores, you can find models of TV tuners with different outputs.
Built-in for PC:
External for PC:
- USB is a common output that every personal computer is equipped with. Such a TV tuner can also be connected to a laptop or car radio. True, set-top boxes with a USB connection are too demanding on processor performance;
- PC Card – bus for connecting to portable computers;
- Express Card is the laptop standard that replaced the PC Card. The difference from the previous model is the increased speed of information transfer.
- PC Card
- Express Card
External for TVs:
- HDMI – a modern port that allows you to transfer the image to the TV in the best quality;
- RCA – two wires transmit audio (left, right), one – video;
- SCART – digital connector for video signal transmission, often found on old technology;
- S-Video – an outdated type of connection, but transmits a picture in better quality than RCA;
- – connector with 15 pins. This is an obsolete type that has been supplanted by digital interfaces;
- SPDIF – designed to transmit an audio signal to electronic equipment.
Based on operating system support
When choosing a TV tuner, consider its compatibility with the installed operating system. If the tuner is connected to a PC, then manufacturers make sure that the devices are compatible with the Windows platform, but you can also find options with Linux and MacOS.
What to look for when choosing an external tuner
When choosing the right set-top box, consider the following:
- Connectors. You need to select those that are present on your home computer or TV, otherwise you will have to additionally look for adapters. In order for the monitor to receive an image in high quality, it is important to have an HDMI port.
- PVR function available. If the tuner supports this extension, then it will be able to record any broadcasts from the TV at the appointed time. The user will independently decide how long this file needs to be stored in the equipment’s memory. Thus, it is possible to carry out delayed viewing.
- USB port available. Often people want to use the tuner not only to connect to digital television, but also to watch movies that can be downloaded to the TV via a USB flash drive.
- DVB-T2 support. You should not buy a model with DVB-T preceding it. This is a waste of money, because in the territory of the Russian Federation.
These functions are enough for the average user for comfortable viewing.
Software is the most important thing in tuners
The installed firmware is the most important part of the device, because it is the one that ensures the functioning of the device. Standard software is installed on each TV tuner, thanks to which the device will perform various functions:
- automatically record specific programs at a specified time;
- adjust image quality;
- display an image on several screens at the same time.
If you need additional features, you will have to look for more expensive tuners with advanced functionality.
Built-in TV tuner
Most of the latest TVs (except the very low end ones) have a built-in TV tuner, so there is no need for an external one.
The built-in decoder can be used to receive several broadcast standards. You will need an external device if you already have a TV, but the installed tuner does not support the required standards.
Professionals recommend buying TVs with only if it supports the desired format (terrestrial, cable, satellite – depending on the chosen operator). This way you can avoid additional costs for the purchase of external equipment.
Which brands are the most reliable
To buy a quality TV tuner, you need to pay attention to popular brands. Their reliability has been tested by time. You can look for models from manufacturers that were active back in the era of DVD players. They felt at ease on the market, and therefore tuners produce high-quality and at an affordable price.

- AVerMedia Technologies;
- World Vision.

Set-top boxes a
On April 15, 2019, the Russians said goodbye to analog television. Now everyone has the opportunity to watch 20 channels of digital television in good quality for free. To do this, you need to purchase only a tuner and a decimeter antenna.
What is a digital set-top box
A digital set-top box, also known as a TV tuner, also known as a DVB T2 receiver, is a device that allows your TV to receive and broadcast free digital TV channels. Simply put, the receiver receives a signal from the RTRS towers through a decimeter antenna and broadcasts it on your TV in analog or digital quality (depending on how modern it is).
Combs, tulips, HDMI?
How to choose a set-top box based on the capabilities of the TV? To do this, simply study which connectors are hidden on the back of your TV.
Modern televisions manufactured after 2015 mostly have a built-in receiver. They can receive digital channels on their own, so there is absolutely no need for a set-top box. To find out if there is a receiver, use the instructions for the TV or enter its model in the browser search engine. On the official website of the manufacturer you will definitely find detailed technical specifications of your model.
Less newer TVs have an HDMI (ash-di-um-ai) connector. This means that the prefix must have an appropriate slot.
Older TVs have either a “comb” (scart connector) or “tulips” – three slots in white, red and yellow (AV connectors). For successful collaboration, you will need a set-top box with a slot of the second type. To use the set-top box with a TV with a comb, simply buy an adapter.
How to choose
First, the choice of digital set-top box should be based on your needs and the capabilities of the TV. The wide functionality of an expensive receiver runs the risk of remaining inexhaustible due to the failure of the TV. But it’s not worth saving on a prefix.
For an analog TV (with “tulips”), it is worth considering simple TV tuners with a convenient remote control, good signal and, preferably, control buttons on the set-top box itself.
For digital and smart TVs, the requirements for set-top boxes are increasing markedly. The TV tuner may also have a slot for memory cards for recording programs or movies, as well as for viewing videos and photos. It is possible to connect the Internet via cable or wi-fi adapter. Then, with the help of TV, you can visit sites and watch videos online, download games and make video calls.
Secondly, look at the quality of the set-top box itself. Experts advise choosing a heavier receiver, because here, as elsewhere, the amount of metal is important.
Country of origin. Almost all TV tuners presented in Russia are made in China. If you don’t find a European model, don’t be discouraged, the Chinese factory assembly is almost in no way inferior to Europe.
We select an antenna
To receive a digital TV signal, you will need a decimeter antenna. Unlike the meter, its elements are much shorter – 15-40 cm. Such an antenna is also called a broadband one.
Home or street?
It directly depends on how far the transmitting center is from you. This can be found on the website of the Russian Television and Radio Broadcasting Network (see number.rf). If you live no further than 15 km from the tower, on a high floor, then feel free to take an indoor antenna. If the tower is located far away, your house is surrounded on all sides by tall buildings or forests, you should consider a more serious antenna.
Connecting and setting up the set-top box
As you have already understood from the above, the set-top box is connected to the TV through the slots available on the TV. To do this, you additionally need special cables such as “tulip”, “tulip-comb” or HDMI.
Set the TV to AV mode and go to the receiver settings. We click on automatic search, and in a few minutes we can enjoy twenty free TV channels in digital quality. For any questions regarding digital television setup, you can contact the direct line RTRS – 8-800-220-20-02.
