Modern Xiaomi TVs based on Android TV or Google TV are powerful multimedia centers, but their basic functionality is often limited to streaming services. For many users, the ability to receive DVB-T2 terrestrial digital television without the use of additional consoles remains critical. The built-in tuner allows you to broadcast channels directly through the antenna cable, providing a stable high-definition image.
The setup process may seem complicated only at first glance, especially given the differences in interfaces between different versions of MIUI for TV firmware. The right antenna configuration and the right choice of scanning parameters ensure access to federal and regional channels in excellent quality. In this article, we will discuss in detail all the stages of connection, from hardware verification to fine-tuning the signal.
It should be borne in mind that the successful reception of the signal depends not only on the software settings, but also on the quality of the antenna cable itself and the location of the receiving device. DVB-T2 Supports models of the Mi series TV, Redmi TV and Mi Stick (when connected via USB-Adapters released after 2018: If your TV is from earlier generations or budget models without a built-in decoder, you'll need an external module.
Compatibility check and equipment preparation
Before you start any manipulations in the TV menu, you need to make sure that your equipment is physically able to receive a digital signal. Most modern Xiaomi models are equipped with an integrated DVB-T2 module, but some budget versions may only specify the DVB-C (cable) or DVB-S (satellite) standard. Checking the technical documentation or having an antenna connector on the back is the first step to success.
Image quality depends on the state of the antenna cable and the antenna itself. If you use a room antenna, make sure it has a signal amplifier, especially if you are far from the transmitting tower. For street antennas, it is important to check the integrity of the connections and the absence of oxides on the contacts, since even a small defect in the cable can lead to a complete absence of images or permanent artifacts on the screen.
Connection is via a standard RF Input or Antenna In connector, which is usually located in a group of main ports on the back or side panel of the case. The cable must be tightly inserted to a characteristic click or stop to ensure reliable electrical contact. After physical connection, you can go to the software part of the setup through the operating system interface.
β οΈ Warning: Don't try to insert the antenna cable by force.The connector is of a specific design, and excessive force can damage the TV's internal contact group, leading to costly repairs.
Digital TV is also important for a stable firmware version. Manufacturers regularly release updates that improve the operation of tuner drivers and signal encoding algorithms. Before setting up channels, you should go to Settings β About TV β System Update and check for new versions of the software.
Step-by-step instructions for automatic channel setting
The easiest and fastest way to access TV channels is to use automatic search mode, which is suitable for most users, because the system independently determines the broadcast frequencies and prescribes the channels found in the device's memory. To start the process, take the remote control and go to the main menu.
You need to find the partition responsible for the signal sources. Depending on the version of the Android TV or PatchWall interface, it can be called Channels, TV or Live TV. Once you log in, the system will suggest selecting the signal source where you want to specify "Antenna" or "DVB-T", and then the scanning process will start.
βοΈ Auto-setting algorithm
During automatic search, the TV will consistently go through all available frequencies in the UHF and VHF range. The screen will display the progress bar and the current execution rate. It is not recommended to interrupt this process, as this may lead to incorrect preservation of the channel list or skipping some frequencies.
Once the scan is complete, the system will suggest you sort channels or remove empty ones, agree to remove inactive channels to make navigation easier later, and if the search is successful, you will see a list of available channels, and switch between them will happen instantly without delay.
β οΈ Warning: If the automatic search found fewer than 10 channels or nothing at all, donβt jump to conclusions about the breakdown.
π‘
Use the "Refresh Channels" feature in the TV menu if individual channels are missing, which is faster than running a full scan again, and helps to recover the missing frequencies after changes to the broadcast towers.
Manual frequency setting and list editing
In situations where the automatic mode is not coping or catching channels with interference, manual adjustment comes to the rescue. This method allows you to specify the TV's exact frequency of broadcasting of a particular multiplex, which is especially true in areas of uncertain reception or when using directional antennas. To switch to manual mode, select "Manual search" in the channel settings menu.
You need to know the frequency of the nearest transmitting tower, and you can find this information on official repeater sites or special digital TV coverage maps. By manually entering the frequency, you force the Xiaomi tuner to look for the signal on this wavelength, ignoring the others.
The manual interface usually contains a frequency slider and a signal quality indicator, and your task is to slowly change the frequency or enter the exact value into MHz by watching the Level and Quality scales, and when both reach maximum values, you can start scanning only this range.
Once you've found channels successfully, you can edit their list, and it allows you to move your favorite channels to the top of the list, hide the unwanted ones, or rename them for convenience, and it creates a personalized TV feed that's tailored to your preferences.
- π Rename: Give channels clear names if the standard ones don't suit you.

Diagnostics of signal and image quality problems
Even after you set it up properly, you can have image quality issues. A DVB-T2 digital signal is different from an analog signal in that it's either there or it's not. If you don't have enough signal power, instead of ripples, you'll see a frozen image, a scattering of the picture into squares, or a full black field with the message, "No signal."
The main cause of problems is often insufficient antenna power or use of too long and poor quality cable. Each connection and each meter of cable causes signal attenuation. If the signal level in the diagnostic menu shows values below 50-60%, you should think about installing an active amplifier or replacing the antenna with a more powerful model.
Also worth looking at are possible sources of interference in the room: Microwave ovens, running Wi-Fi routers, and other electronic devices can create interference, especially if you use a room antenna without filtering. Try turning off nearby electronics and see if the reception quality changes.
For accurate diagnosis, use the TV's built-in tools. The channel menu often provides real-time technical level display, which allows you to position the antenna accurately to achieve maximum performance.
| Parameter | Normal value. | Critical significance | Action. |
|---|---|---|---|
| Signal level | 70-100% | Less than 40% | Replace the antenna/cable |
| Signal quality (BER) | High. | Low/Constant Errors | Direct the antenna more precisely. |
| Signal strength (dBΒ΅V) | 60-80 dBΒ΅V | Less than 45. dBΒ΅V | Install the amplifier |
| Stability | No horse racing. | Sharp falls | Check the contacts |
β οΈ Note: If the signal quality indicator jumps from 0% to 100%, this often indicates a re-reflected signal or interference. Try changing the position of the antenna or using an antenna with a different directional diagram.

The stability of a digital signal is more important than its peak power, and it's better to have a stable 60% of quality than a galloping 90% that causes images to freeze.
Use of an external tuner and USB-adapter
If your Xiaomi TV model doesnβt have a built-in tuner DVB-T2 or it's out of order, the only solution is to use external equipment. TV support the connection USB-This is true for older models and compact versions like the Mi Stick, which don't have a physical antenna socket.
When choosing an external adapter, it is important to pay attention to support for the DVB-T2 standard and compatibility with the Android TV operating system. Not all drivers are universal, so before buying it, you should make sure that the manufacturer claims support for your version of the OS. The connection is via a USB port, and the antenna cable is inserted directly into the adapter housing.
Once the device is connected to the system, the TV must automatically identify new hardware and offer to install the necessary drivers or app for watching TV. The Google Play store has many applications-players, such as Live Channels, TiviMate or specialized software from the manufacturer of the tuner, which allows you to manage the list of channels and reception settings.
The advantage of external tuners is their mobility and the ability to use on multiple devices. You can easily transfer the adapter to another TV or even use it with a tablet if it supports the OTG function. However, it is worth remembering that channel management will occur through the application interface, not the standard TV module.
- π Power: Some powerful tuners require additional power via Y-shaped cable USB.
- π‘ Compatibility: Make sure the adapter supports the codec H.265 (HEVC), which is used for broadcasting in high resolution.
- π± Appendix: It often requires installing a third-party app from the Play Market, as a standard player may not see the external module.
