Modern Xiaomi TVs with Android TV offer users a wide range of options for viewing content, but the basic feature of receiving terrestrial television remains a priority for many owners. The initial setup process can seem difficult due to the features of the PatchWall or Android TV interface, which are significantly different from the usual menus of older models.
In this article, we will discuss in detail the algorithm of actions necessary for successful frequency scanning, and consider the nuances that arise when using different types of antennas. It is important to understand that digital television requires more accurate adjustment of receiving equipment than analog signal. Even a small error in connecting a cable or choosing a region can lead to a missing image or a message about the absence of a signal.
Before you go to software settings, you need to make sure that the physical integrity of the connections is in place. The antenna cable must be tightly inserted into the corresponding connector on the back of the device, and the antenna itself is correctly directed towards the repeater. Ignoring this step often leads to the fact that automatic search does not find any channel, even if the TV firmware is fully functional.
Connecting antennas and preparing equipment
The first and most critical step is to physically connect the signal source. On the back of Xiaomi TVs, whether Mi TV series models or newer lines, there is usually a connector labeled ANT IN or RF Input. This is where you need to connect a coaxial cable coming from a room or an external antenna. Make sure that the cable has no bending and the plug sits tightly in the socket, since poor contact is the main cause of unstable reception.
If you are using an active antenna (amplifier), check if it is powered. In some Xiaomi TVs, there is an option to power the antenna through the antenna input, but most often a separate power supply or injector is required. Lack of power on the active antenna will cause the signal level to be critically low, and automatic adjustment will not be able to detect multiplexes.
⚠️ Warning: Never connect a satellite receiver or cable operator cable directly to the TV's antenna input unless the signal is passing through a standard modulator.
For users living in areas of insecure reception, it is recommended to use external antennas with a high gain, aimed strictly towards the nearest tower. Internal antennas are effective only in the immediate vicinity of the transmitter. The quality of the cable also plays a role: use a cable with a resistance of 75 Ohms and a high-quality shield to minimize signal loss on the way to the TV.
Automatic setup of digital channels
After checking the physical connections, you can go to the software part. The interface of Xiaomi TVs may differ depending on the installed version of the shell, but the logic of the actions remains similar. You need to get to the main menu of system settings. To do this, click the button with the image of the gear on the remote control or select the corresponding item in the upper right corner of the main screen.
In the menu that opens, find the TV section, which can be called Channels, TV or Broadcasts depending on the regional firmware, and within this section, select Channel Configuration or Channel Search. The system will suggest that you select the signal source: you specify the antenna (or DVB-T2) if you use on-air broadcasting, and not confuse this with a cable or satellite.
☑️ Checking before launching the search
Then you start scanning the frequencies, you'll see the progress bar and the current signal level, and the TV will consistently check the entire frequency range, trying to capture and decode the digital stream, and interrupting this process can lead to an incomplete list of available channels, so wait until you've finished the operation, even if it seems that the search is 99 percent frozen.
When the scan is complete, the system will suggest sorting the channels found or skipping the blank ones. It is recommended to agree to sorting the list of broadcasts by numbers, which will simplify navigation in the future. If the automatic search does not give results, move to manual settings that allow you to work with specific frequencies.
Manual frequency setting and list editing
Manual mode is required in cases where automatic search can not stable signal or misses some packets of channels. To switch to this mode, select the settings manual settings. Here you will need to enter specific parameters: channel frequency (in MHz) and bandwidth (usually 8 MHz for DVB-T2). These data can be found on the official website of digital television in your region, entering your address in a special coverage check service.
In manual mode, you can monitor the signal quality in real time. The screen displays the signal level and signal quality scales. Your task is to achieve maximum values, perhaps by rotating the antenna or changing its position. The green quality scale indicates that there are no errors in the data packet and the image will be broadcast without artifacts.
| Parameter | Value for DVB-T2 | Description |
|---|---|---|
| Signal type | Digital/Digital | Digital stream reception mode |
| Frequency | 474 - 858 MHz | Depends on the channel number and region |
| Strip width | 8 MHz | Standard broadcast channel width |
| Modulation. | QAM 64 / Auto | Signal encoding method |
Once you've successfully captured the frequency manually, you can add this channel to the general list, and in the channel editing menu, you can rename them, hide empty channels, or tag favorites, which is especially useful if you've lost radio stations or technical channels that are not of interest to view.
