Modern TVs Xiaomi Mi TV redmi TV These are powerful multimedia centers, but their basic functionality without a tuned TV often seems limited to users. After the first switch on and Wi-Fi connection, many owners are faced with the question of how to activate the reception of on-air broadcasts to watch news and movies in high resolution without delay. HD.
The process of scanning frequencies on Android TV or PatchWall may be different from the usual algorithms of older TVs, due to updated interfaces and the integration of smart features that sometimes hide the classic settings menu. In this article, we will discuss in detail all the steps necessary for your screen to broadcast a quality video stream.
It's worth noting that the success of the operation depends on the quality of the antenna connected and the right choice of the signal source in the device menu. Whether you use a room antenna in the apartment or an outdoor antenna in the country, the software part of the setup remains similar for most models of the brand. Let's move on to the direct preparation of the equipment.
Preparation of equipment and connection of antenna
Before diving into the settings menu, you need to physically connect the signal source. The digital tuner built into Xiaomi TVs supports the DVB-T2 standard, which is the main standard for broadcasting in many countries. You will need an antenna with an F or IEC connector that connects to the corresponding socket on the back of the case.
If you live in a sensitive reception area, the use of an active signal amplifier can be a crucial factor. Passive antennas (without an amplifier) only work well in the vicinity of the transmitting tower. Satellite-Broadcast (DVB-S2) models will require a cable connection from a satellite dish, however, most budget and mid-range Redmi TV models have only an on-air tuner.
⚠️ Warning: Make sure the antenna cable is tightly inserted into the connector before the characteristic click.A backlash or poor contact will result in permanent signal loss and artifacts on the screen, even if the settings are done correctly.
After you physically connect the cable to the TV, turn on the device and wait for the desktop to load. If you're using an active antenna, make sure it's also connected to the power source, if the design provides it. Only after checking all the connections can you go to the software part.
💡
Use a double shield cable if the wire is longer than 5 meters to minimize signal loss and interference.
Automatic setup of digital channels
The easiest and most common way to get a broadcast list is to use automatic search, which allows the system to independently scan the entire frequency range and save the streams found. To start the procedure, you need to go to the main menu and find the settings section, often indicated by the gear in the upper right corner of the screen.
In the menu that opens, select Channels or Television, and then search for Channel Search. The system will suggest selecting a signal source: specify an antenna (DVB-T) for broadcasting, and then start the scanning process, which can take from 2 to 10 minutes depending on the number of frequencies available in your region.
- 📺 Click the Menu button on the remote for quick access to sources.
- 🔍 Select “Autosearch” in the tuner settings window that appears.
- 📡 Make sure you choose Digital mode, not analog mode.
- ✅ Wait for the progress bar to be completed and save the changes.
The scanning process can display the current frequency and signal strength, and if you see that the signal level is critically low at some frequencies, it may indicate problems with the antenna or the direction of its installation, and when the process is complete, the TV will suggest you sort the channels or switch to the first one you find.
☑️ Checking before auto search
Manual tuning and working with frequencies
In situations where automatic search does not find all available channels or finds them with decoding errors, you have to resort to manual adjustment, this is especially true for remote areas where the signal is broadcast at specific frequencies that the automation may miss.
You're going to need to know the exact frequency of multiplexes in your area, and you can find that data on official relay site, and you're going to manually type in the frequency, and you're going to check out the TV to check that range, which is often what you can pull out where you can't find the search.
| Parameter | Description | Recommended value |
|---|---|---|
| Frequency | Channel number or MHz | Depends on the region (e.g. 538 MHz) |
| Modulation. | Type of signal encoding | 64 QAM or 256 QAM |
| Bandwidth | Channel width | 8 MHz |
| Code FEC | Correction of errors | Auto or 3/4 |
When manually adjusting, it is important to specify the modulation parameters correctly. Most digital terrestrial television uses QAM-64 or QAM-256 modulation. If the signal quality scale remains empty after entering the frequency, try changing the modulation type or checking the direction of the antenna.
What to do if the quality scale jumps?
Set up IPTV and online cinemas
Owners of Xiaomi TVs with Android operating system TV They have the unique ability to watch television over the Internet, bypassing the traditional antenna. IPTV It allows you to broadcast hundreds of channels in high quality using only a Wi-Fi connection or a high-quality channel. LAN-To do this, you need to install a specialized application from the Google Play store.
There are many IPTV watchers, such as Peers.TV, Lime HD TV, or universal players like OTT Navigator. Once you install the app, you'll need to enter your ISP's data or use the free playlists available online, which is a great option for a summer cottage or office where you can't install an antenna.
Internet connection speed is critical to IPTV stability. It is recommended to use a wired connection via a LAN port, as the Wi-Fi signal can be unstable when streaming high-resolution video. If you are using a wireless network, make sure that the router supports the 5 GHz band.
⚠️ Note: When using free of charge IPTV-Keep in mind the security and instability risks of broadcasting, official ISP applications provide a more reliable data stream.
Solving Signal and Image Quality Problems
Even after a successful setup, users may face problems: the picture falls apart into squares, the sound lags behind the video, or the channels periodically disappear. The first step in diagnosis is to check the signal level in the TV information menu. Press Info button or call the status menu to see the current readings.
A common cause of problems is overloading the tuner with a too powerful signal, which often happens when using active amplifiers near the tower. In such cases, it may be necessary to attenuate the signal or turn off the power of the amplifier. It is also worth checking the integrity of the cable: bending, contact oxidation or insulation damage can completely disrupt the data transmission.
If the problem is only seen on certain channels, the broadcast tower may be performing preventive work or have temporary failures. In the case of complete absence of channels after resetting, try to perform a complete reset of the TV to factory settings, but save the account data beforehand.
- 🔌 Reconnect the antenna cable by checking the plug for oxides.
- 🔄 Perform a second automatic search after rebooting the TV.
- 📡 Change the position of the antenna to improve direction.
- ⚙️ Update your TV software to the latest version.
💡
The image quality is 90% dependent on the state of the antenna cable and the correctness of its connection, not just the settings of the TV.
Update and work with firmware
Xiaomi TV operating system receives updates periodically, which may include fixes for the built-in tuner and improve the stability of applications. It is recommended to regularly check for updates in the Settings → About TV → System Update. New firmware versions often optimize the work with codecs and broadcast protocols.
Sometimes, after a major update, channel settings may get lost or require recalibration, which is normal for the system to change the software base, and in rare cases, users encounter bugs when the channel list becomes empty, in which case cleaning the cache of the TV application through the application management menu helps.
For advanced users, there is the possibility of installing third-party firmware, but this carries the risk of loss of warranty and can lead to incorrect operation of regional tuner settings. Official global versions of Xiaomi TV firmware are the most stable for working with international broadcast standards. Use only proven sources for updating.
