Owners of modern Xiaomi Smart TVs often encounter a confusing message on the screen, where the system notifies that the content is “encrypted” or cannot be played, this error usually occurs when trying to watch movies from an external drive or through an HDMI cable, and it is associated with the protection of digital rights of the DRM or file system.
The main reason is that Android TV, which runs the TV shell, has strict restrictions on reading certain file formats and protecting the video stream. If you see an encryption message, it means that the media player does not have the rights to decode the signal or can not read the disk structure.
In this article, we will discuss in detail all possible scenarios of error, from problems with the problem of the problem. USB-You'll learn how to bypass the limitations of the file system and adjust the output settings to work correctly. HDCP protocol.
Reasons for the Encryption Report
The first thing to understand is that the nature of the message "encrypted" can be different, most often it is about multimedia files that the TV refuses to open, the Widevine content protection system or PlayReady can block playback if it believes that the connection is not secure, this is standard practice for streaming services and licensed content.
The second common reason is the file system of an external hard drive or flash drive. Xiaomi TVs by default read FAT32 format perfectly, but with it there is a limit to file size to 4GB. If you try to run a movie in high quality that weighs more, the system can issue an access error, interpreting the inability to read as an encryption or format problem.
You also need to consider the human factor and the settings of the signal source. When you connect a laptop or console via an HDMI cable, the TV may not receive the correct handshake signal, which confirms that copy protection is available. Without this confirmation, the image may not be displayed, and a black background or error message will appear on the screen.
- 🛑 Incompatibility of the file system of the drive (NTFS against exFAT)
- 🔒 Blocking Content with Protection Protocols DRM (HDCP 2.2/2.3)
- ⚙️ Incorrect resolution or frame rate settings at the signal source
It is important to note that some files can be protected by a digital key that is tied to a particular device or account, in which case simply copying a file to another medium will not help, but when it comes to personal video archives, the problem almost always lies in the codec or file container, which the built-in MI TV player does not support.
Problems with external storage and file system
The most common scenario is connection USB-If your hard drive is formatted into NTFS, Xiaomi TVs usually read it without problems, but sometimes there can be access rights conflicts, especially if the drive was previously used on a PC with BitLocker encryption enabled.
The exFAT file system is more modern and supports large files, but older TV models may not have drivers to work with it, so the user sees the connected device, but when you try to log in to the folder, you get an error message or encryption, and checking the disk format is the first step in diagnosis.
⚠️ Attention: Formatting a disk will delete all data on it!Be sure to copy important files to your computer before changing the file system.
To solve the problem, you need to connect the disk to a Windows computer. Go to disk management and check the status of the volume. If you mark "Encrypted", you will need to remove BitLocker protection. If the problem is in the format, you need to format the disk into a compatible file system, selecting NTFS for maximum compatibility with large files.
☑️ Verification USB-storage
Another nuance: nutrition USB-Powerful 3.5-inch hard drives may require additional power, and if the TV doesn't have enough current to spin the disk, it may misidentify its structure by sending out erroneous messages. USB-hub.
Setup of video playback and codecs
Xiaomi’s built-in TV media player supports basic formats, but not all. If you downloaded a movie in a rare container or with the latest HEVC (H.265) 10-bit codec, the standard player may not be able to handle decoding, reporting file inaccessibility, which is often perceived by users as an encryption error.
The solution is to install third-party software. The Google Play app store on your TV allows you to download powerful players like VLC or MX Player. These apps have their own codecs and are independent of the system limitations of Android TV, allowing you to open almost any video file.
You also have to pay attention to subtitles. Sometimes a video file opens, but the encryption message appears when you turn on the subtitle track, if it's in a complex format or encoding, and disabling the subtitles in the player settings helps diagnose this narrow problem.
Which codecs are best supported?
If you use Network Storage (NAS) or stream video from your phone over DLNA, make sure the server doesn't require authorization that the TV can't provide.In some cases, the router may block streams of certain formats if parental controls or firewall features are enabled.
Errors when connecting via HDMI
When a TV writes "encrypted" or shows a black screen when you connect a laptop, game console or TV set-top box via HDMI, it is associated with the HDCP (High-bandwidth Digital Content Protection) protocol, which is copy protection, which checks the chain of devices. If at least one link (cable, adapter, port) does not meet the standard, the signal is blocked.
Often the problem arises when using cheap adapters, such as HDMI-to-VGA or older versions of cables that do not support the required bandwidth for 4K HDR content. In this case, the Android TV receives a signal, but can not decrypt it to output the image.
If the computer is giving a signal with a refresh rate that the TV does not support in a given color format (for example, RGB 4:4:4 at 60 Hz), there may be a conflict.
| Type of connection | Probable cause of error | Decision |
|---|---|---|
| HDMI (Laptop) | HDCP inconsistency | Replace the cable with High Speed |
| USB (Flash drive) | NTFS/exFAT file system | Formatting or third-party player |
| Online cinema | Obsolete application software | Update via Google Play |
| Satellite receiver | Problem with the CI+ module | Reconnect the smart card |
On Xiaomi TVs, some HDMI ports can be optimized for different features (for example, one port supports eARC or has version 2.1).
Failures in the work of applications and online services
If the “encrypted” error appears inside apps like YouTube, Netflix or online cinemas, it indicates a problem with digital certificates. Services protect content from piracy, and if the system time on the TV is shot down or the security certificate has expired, access is blocked.
First, check the date and time in the settings → The device → Date and time. Set up automatic synchronization over the network. Even a slight deviation in the dates can cause you to have a problem with the timing. SSL-Certificates will be considered invalid and the data flow will be interrupted.
The second step is to clear the cache of the problem application. Go to Settings → Apps → All applications, find the service you want, and select Clear Cache and Erase Data, which will return the application to its original installation state by deleting any conflicting temporary files.
💡
If the application data reset didn’t help, try to completely uninstall the app and reinstall it from the Google Play Store.This ensures the latest compatible version is downloaded.
In some cases, ISPs may block access to update servers or services themselves. Try handing out the Internet from a mobile phone (via a Wi-Fi router) and see if access is available. If mobile Internet is working, the problem is on the provider's side or on the other side. DNS-server.
CI+ Access Card and Digital TV
A separate category of issues is related to the built-in DVB-T2 digital tuner and the CI+ access module. If you use an operator card to view pay channels, an encryption message may mean that the TV cannot authorize the card.
Make sure the card is inserted on the correct side and all the way. The card and slot contacts should be clean. Sometimes it helps to clean the card contacts carefully with soft dry cloth. Also check if the card is activated by the operator - often new cards require activation via the site or call.
The TV menu in the Channels or CI+ section may require updating the channel or authorization key list. Find Update or Map Activate in the digital TV settings. Without this procedure, even the working card will not give access to the encrypted broadcast.
⚠️ Attention: Do not remove the card CI+ when updating the channel list or the module firmware, this can damage the data on the map and completely block access to the operator's services.
If the TV says the module is undefined or the card is not readable, try removing the card, turning the TV off the socket for 1-2 minutes, then turning on, inserting the card again and waiting for the system to boot.The full reboot cycle often resets the slot's power controller errors.
Radical methods: Resetting and flashing
If none of the software methods worked, it could be that the system has accumulated critical file errors or damaged the system libraries responsible for decoding video, in which case the effective method is a complete reset to factory settings.
To do this, go to Settings → Device → Reset. Remember, this action will delete all installed apps, accounts and settings. Once reset, the TV will be like new, and you will need to reconfigure Wi-Fi and install applications. This often resolves deep-seated software conflicts.
💡
Factory Reset eliminates 95% of software errors associated with codec and system libraries conflicts, unless the problem is caused by a hardware malfunction.
In extreme cases, when even a reset doesn’t work (for example, problems with specific HDMI ports after a failed update), you may need to flash the TV via USB. Official firmware can be found on the Xiaomi support website.The process requires accurate follow-up instructions, as interrupting the firmware record can turn the TV into a “brick”.
