System program Broadcast on Xiaomi: functions and configuration

Owners of Xiaomi, Redmi and Poco smartphones often notice a system process called Translation in the list of installed applications or in notifications. Many users immediately become worried that it is a virus, spyware or junk that only consumes battery power. MIUI or hyperos.

In fact, Broadcast is a critical system component that provides wireless multimedia content, and without it, you can't display images from your phone to your TV, use the Second Screen feature to work with your PC, or stream videos to a smart speaker, and shutting down the service can cause unstable interfaces and loss of wireless connectivity.

In this article, we will discuss in detail what role this application plays in the Android architecture, why it can consume resources and how to properly configure it for comfortable use, you will learn how standard broadcasting differs from third-party solutions and whether it is worthwhile to interfere with the operation of system processes at all.

What is a System Application Translation

The Broadcast app is a native component of the Android operating system that smartphone makers including Xiaomi integrate into their shells. Its primary task is to implement wireless data protocols such as Miracast, DLNA, and proprietary Xiaomi Share technologies. When you click the “Translate” button in the YouTube app or “Plug” button in the notification curtain, this is the background process that starts.

It's important to understand that it's not just a player or a browser, it's a bridge between your smartphone's GUI and the external display, and it encodes the video stream in real time, compresses the audio track, and sends packets of data over Wi-Fi or Wi-Fi Direct, which is why when you use it, it can get hot -- the processor does the hard work of encoding the image.

Many people confuse this application with the Wireless Projection function, which is in the curtain. In fact, these are two sides of the same coin: the widget in the curtain is the control interface, and the system application is the engine that does the technical part of the work. Without the Translation package installed and running, the button in the curtain will either be missing or give an error when pressed.

⚠️ Note: Attempt to remove the system application "Translation" through ADB or third-party utilities can lead to the disappearance of the screen control button, malfunctions in Bluetooth headsets with the audio transfer function and errors in applications such as Google Home.

Main functions and capabilities of the protocol

The feature of the built-in streaming on Xiaomi devices goes far beyond just duplicate screen. Modern versions of the MIUI shell offer advanced multimedia and work capabilities. First of all, it is support for high resolution. Mid-range and flagship smartphones are able to transmit images in 1080p and even 4K resolution with a compatible TV and stable network.

The second important feature is the background, and unlike some cheap ones, the system broadcast allows you to fold the source app, for example, you can run the navigator on your phone, display the map on your TV, and then you can safely chat in the messenger, and the system will divide the streams, although in some scenarios the sound can switch to the speaker of the phone.

And it's also worth noting that it supports audio tracks, and it allows you to stream not only video, but also audio from any application, including browsers that don't have a built-in "Cast" button, and it turns your smartphone into a universal remote control for your home audio system, so you can run a podcast or an audio book on your phone, and the sound will go through the powerful speakers of your TV.

• 📺 Screen Duplication: Full copy of the image from the smartphone to the large display in real time.
• 🎮 Game mode: Minimize latency for cloud gaming or running mobile games on TV.
• 🔊 Audio casting: Transmitting only sound stream to save battery power and use TV as Bluetooth speakers.
• 🖥️ Presentation Mode: Ability to hide notifications or individual windows when displaying an image on an external screen.

How to turn on and configure the broadcast on Xiaomi

Activating a function doesn't usually require complex manipulations, as it's built deep into the system. The standard launch path is this: unlock the device and lower the top notification curtain. Find an icon called Translation, Wireless Projection, or Cast. If there's no icon, tap on a pencil or three dots to edit the Quick Access panel and drag the desired item to the visible area.

Once pressed, the system will start searching for available devices within Wi-Fi range. Make sure your TV or set-top box is on and on the same network as the smartphone. Xiaomi uses device detection technology, which can take anywhere from 3 to 10 seconds. If a device is found, just tap its name on the list.

To fine-tune the image quality, you can use the hidden developer settings, although for most users, standard values will work. In some firmware, codec settings and resolutions are available through the Settings menu → Connected devices → Translation. Here you can choose the priority: image quality or response speed.

There is also an alternative way to run through settings. Go to Settings → Connect and Sharing → Broadcast. In this menu, you'll see a more detailed list of options, including your device name that others see and connection history. This is especially useful if you often connect to different projectors in the office.

Technical requirements and compatibility of devices

There are a number of specifications that need to be met to make it work properly, including the operating system and hardware version, and almost all Xiaomi smartphones released after 2016 support the Miracast standard at the hardware level, but the software implementation may vary depending on the Android version.

Connection type is critical. High-quality video (Full HD and higher) requires support for 5GHz. In the 2.4GHz bandwidth is often insufficient for streaming video without delay, leading to image artifacts and audio desynchronization. If your router is dual-band, make sure both devices are connected to a 5GHz network.

Older TVs may not support the current compression codecs used by newer Xiaomi smartphones, in which case the system may suggest lowering the broadcast quality or using an external adapter, such as a Chromecast or MI TV Stick, which will take over the signal decoding.

💡

If you're twitching, try temporarily disabling the "Smart Connect" feature on your router, which connects 2.4 and 5 GHz networks into one. Force your phone to connect to a 5 GHz network.

Problem Solving: Advertising and Connection Errors

One of the most common complaints of Xiaomi users is the appearance of banner ads in the interface of the Translation app or when searching for devices.This is a really annoying aspect of free firmware, but it can be eliminated.

To get rid of ads, you need to turn off personalization in system services. Go to Settings → Passwords and security → Access to personal data. Find the "msa" list (MIUI System Ads) and turn off the slider. Wait 10 seconds and confirm the shutdown. This action blocks the loading of ad modules in many system applications, including broadcast.

The second common problem is the "failed to connect" error or the persistent disconnection of the connection, often not with the phone, but with the router settings. Broadcast protocols are sensitive to IGMP Snooping settings and AP Isolation. If you have a complex home network with multiple routers, make sure that the phone and TV are in the same network segment.

⚠️ Note: If the function stopped working after the firmware update, do not rush to reset the settings. Often the problem is solved by cleaning the Translation app cache through the Applications menu» → «All applications» → Show system-based → Broadcasting → Clean up.

Another nuance is the conflict with VPN. If the smartphone is activated VPN-tunnel, Android security system can block local data transmission, considering it potentially unsafe. VPN You must temporarily disable or configure exceptions for local addresses.

Differences from Third-Party Analogues and Alternatives

Users often ask why you need a system broadcast when you have applications like Web Video Caster or TeamViewer. The main difference is the level of access to the system. Third-party applications run in a sandbox and do not have direct access to the video output, so they either stream only content from the browser or create a virtual display, which is a lot of load on the processor.

Xiaomi’s system solution works at the level of display drivers, which provides minimal input lag, which is critical for games. Third-party programs often give a delay of 200-500 ms, making dynamic games unplayable, whereas native broadcasting can be in 50-80 ms on good screens.

In addition, system broadcasting is better optimized for energy saving, it can aggressively lower bitrate when the screen is static, or turn off the video stream if only audio is broadcast. Third-party applications often keep the screen and processor active all the time, which leads to a rapid battery drain.

💡

Xiaomi’s native broadcasting provides better performance and less power consumption compared to third-party counterparts, as it has direct access to the device’s hardware codecs.
