Modern Xiaomi Mi TVs are powerful multimedia centers based on the Android TV operating system. Despite the abundance of streaming services and applications, many users still prefer traditional terrestrial broadcasting. DVB-T2 digital TV provides high quality picture and sound, as well as stable reception without ripples. However, the initial setup can cause difficulties for those who are faced with the MIUI for TV interface for the first time.
The activation process depends on several factors: the type of connection, the availability of a built-in tuner and the version of the software. Owners of models released for the global market usually do not have problems, since their devices are fully adapted to European broadcast standards. At the same time, versions for the Chinese market may require additional manipulation or use of an external console.
In this guide, we will take a look at all the steps of connecting an antenna, finding channels, and fixing common bugs. You will learn how to adjust frequencies correctly, check signal strength, and optimize playlist. Quality tuning will allow you to enjoy your favorite transmissions in Full HD or even 4K resolution if the broadcast content supports high detail.
Compatibility check and equipment preparation
The first step before setting up is to carefully check the specifications of your device. Not all Xiaomi TVs are equipped with an integrated module for receiving an air signal. This is especially true for some budget models or devices designed exclusively for use with external media players. The presence of a DVB-T2 tuner is a prerequisite for connecting a conventional indoor or outdoor antenna directly to the socket on the back.
If your Mi TV Stick or Mi Box specifications don't include DVB-T2 support, you'll need a separate set-top box. Built-in tuners usually support not only digital but also analog broadcasting, but the relevance of the latter is rapidly declining. Make sure you have a serviceable antenna with a signal amplifier if you're in a troubled area. Also prepare a remote control, as it is the one that navigates the menu.
For good reception, distance to the transmitting tower is critical: in urban settings, a room antenna is often enough, whereas in rural areas, a directional roof structure may be required, the coaxial cable must be intact, without clamping or insulation damage, and the connectors must fit tightly to the sockets.
⚠️ Attention: Using an antenna amplifier without need (in the zone of confident reception) can lead to overload of the tuner and deterioration of image quality, causing the effect of "digital cubes".
Before you go to the software part, make sure that the TV is connected to the power grid and the antenna cable is securely inserted into the ANT IN or DVB-T connector. It is not recommended to switch cables while the device is on to avoid potential voltage surges, although modern models have protection. After the physical connection, you can move to the software configuration.
Physical connection of antenna cable
The image quality is directly dependent on the reliability of the physical connection. On the back of the Xiaomi Mi TV, and sometimes on the side, there is an antenna jack. It can be signed as Antenna, RF In or have a standard socket designation. Put the antenna cable plug to the end. If you use an active antenna with a separate power supply, remember to connect it to the socket.
In some cases, users are faced with a situation where the standard plug is not suitable or the socket is located in a difficult place, in such situations, you can use an angle adapter or an extension cord, the main thing is to ensure that the central vein of the cable is tightly contacted with the contact inside the TV socket. Poor contact often causes periodic signal loss or complete absence of channels.
☑️ Connection check
If you use a system of multiple TVs through a splitter, make sure that the signal level on each device is sufficient.Separating the signal weakens it, so a more powerful amplifier may be needed.After checking all connections, turn on the TV using a button on the case or remote.
Initial setting and region selection
When you turn on your Xiaomi TV, you need to get to the main menu. If you're launching your device for the first time, you're welcomed by the original setup wizard. At this point, it's critical to choose the right country and language. Regional settings determine the list of available frequencies and the order of sorting channels. For Russia and CIS countries, the appropriate country or option is usually selected./Europe", if there is no exact match.
In the initial configuration, the system may suggest connecting to a Wi-Fi network. Although the Internet is not required for terrestrial TV, its presence will allow the TV to automatically update the frequency database and program modules of the tuner. Go to the Settings section (the gear icon in the upper right corner) to check the relevance of the date and time. The wrong time can knock down the electronic program guide (EPG).
Android TV interfaces can vary depending on the firmware version. In newer models, the settings menu is placed in a separate unit, while in older versions of PatchWall it is integrated into a shared feed. Find the channel or broadcast item. It can be called Channels, Translation or Live TV. If you missed the setup step on the first turn on, all settings can be changed manually through the menu.
It is important to note that changing the region after the initial setup may require resetting all channel settings, so it is better to set the correct settings right away. If the TV was purchased in China (Global Version), make sure that the settings select a region other than China to activate the global frequency grids.
Automatic search for digital channels
The easiest and most recommended way to set up is to start an automatic search. To do this, go to the settings menu and select Channels or Broadcast. In the menu that opens, find Channel Configuration or Channel Search. The system will suggest choosing a signal source: select Antenna or Etheric TV, so as not to search for satellite or cable signals.
The TV will then suggest you select the search mode. Auto Search is the optimal option. In this mode, the scanner will sequentially check all frequencies in the DVB-T2 range, save the found video streams and audio tracks, and try to download the channel names. The process can take from 3 to 10 minutes depending on the number of multiplexes available and the speed of the TV processor.
The scan shows the progress bar and the current signal level. Interrupting the process may lead to an incomplete list of channels. If the search is complete but 0 channels are found, check the antenna connection again and repeat the procedure. In some cases, reconnecting the cable directly during the search helps, although this is not a standard recommendation.
| Parameter | Description | Recommended value |
|---|---|---|
| Tuner type | Broadcasting standard | DVB-T2 / DVB-C |
| Search mode | Method of scanning | Automatic. |
| Type of channel | What to look for | All (TV + Radio) |
| Network | Signal source | Antenna (Ether) |
Once the scan is complete, the TV will suggest you sort the channels or skip this step. It is recommended to sort to remove empty or technical channels from the list. Save the changes, and you can switch between channels using volume buttons or a separate Channels button on the remote.
Manual Frequency and Multiplex Adjustment
In situations where automatic search is not yielding results or not finding all channels, you need to resort to manual adjustment. This is true for remote areas or places with complex terrain, where only specific frequencies receive the signal. First, you need to know the frequencies of the nearest transmitting towers. This information can be found on the official digital mapping website by entering your address.
In the channel settings menu, select Manual Search. You will need to enter a channel number or frequency in MHz. In Russia, digital TV is broadcast in packets (multiplexes). The first multiplex usually includes 10 main channels, the second one - 10 more, and the third one depends on the region. When entering the frequency, monitor the indicator Signal Level and Signal Quality. If the scales are filled, click "Search" or "OK" to scan a specific frequency.
What if only a part of the canals are caught?
Manual mode also allows you to adjust the modulation parameters if the standard values do not work. 99% In some cases, it is enough to leave the default parameters: bandwidth 8 MHz, modulation QAM64 or QAM256, coding FEC 2/3 or 3/4. This data is standard for broadcasting DVB-T2.
⚠️ Note: When manually configured, do not delete the automatically found channels until all frequencies are checked, otherwise you may lose access to live broadcasts.
Once you successfully manually add the frequency, the channels will be on the list, repeat the procedure for all multiplexes available in your area, which is a more time-consuming process, but it ensures that the signal is found even in the most difficult reception conditions.
Configuring cable television (DVB-C)
If you connect a Xiaomi TV not to an antenna, but to the provider’s cable network, the procedure differs in the choice of the signal source. In the channel settings menu, select the cable connection type or DVB-C standard. Unlike on-air broadcasting, it often requires additional authorization or the introduction of specific network parameters that the provider provides.
In most cases, providers use automatic diffusion. Select Automatic search in cable TV mode. The TV scans the frequency range typical of cable networks (usually from 48 to 860 MHz). If the provider uses encryption, you may need an access module. CI+ (CAM-module) inserted into the Common Interface slot on the back of the TV.
Insert the provider's access card into the module, then the module into the TV slot. Then activate the CI module in the settings menu. Without this card, even if there is a signal, the channels will be encoded, and you will see only a message about the lack of access rights or a black screen. Make sure that the module is inserted on the correct side, as indicated on the diagram next to the slot.
💡
If the cable provider does not provide CAM-Module, see if it has its own Android app TV. Installation of such an application can eliminate the need to purchase additional equipment and use the slot. CI+.
Network settings for cable TV, such as network frequency and streaming speed, are usually determined automatically, but if the search does not yield results, request this data from the provider's technical support and enter it in the appropriate fields in the manual setting menu of DVB-C.
Elimination and tips for signal improvement
Even after the right setup, users can face problems: the image crumbles into squares, the sound lags behind the video or the channels periodically disappear. Most often the cause lies in a weak signal or interference. Check whether the antenna is near powerful sources of electromagnetic radiation, such as routers, microwaves or power supplies. Electromagnetic interference can significantly impair the quality of reception of a digital signal.
If the signal level is low, try to change the position of the antenna or replace the cable with a better, shielded one. Long cables (more than 20 meters) without an amplifier can also weaken the signal. In this case, installing an active amplifier closer to the antenna will help. It is also worth checking the contacts in the connectors: oxidation or dust can disrupt data transmission.
In rare cases, the problem may be with the TV software. Make sure your Android TV system is updated to the latest version. Manufacturers regularly release patches that improve tuner performance and connection stability. Go to Settings → About TV → System Update and check for new versions.
💡
The stability of the digital signal depends not only on the antenna, but also on the quality of the cable, the absence of interference and the relevance of the TV firmware.
If none of these methods worked, try resetting the channel settings completely and running the search again. Sometimes the tuner's memory accumulates errors that interfere with the correct operation, resetting the broadcast parameters back to factory values and eliminating programming conflicts.
