The fourth-generation smart box from Xiaomi can "enhance" the functionality of any television, regardless of whether it has a pre-installed SmartTV system or not.

Functional Interface

The device operates under the sixth version of the "green droid," offering access to a wide range of compatible applications in the Google Play Market. The proprietary PatchWall interface with artificial intelligence is layered on top of the Android OS — a virtual assistant that learns users' habits and suggests content recommendations based on their preferences. Additionally, it can recognize different voices, adjusting to various viewers.

Practical Remote

Interacting with the TV set-top box is facilitated by a functional remote control, which connects to the media player via a Bluetooth network. The remote has a built-in microphone for receiving voice commands, accurately recognizing user speech. Gaming joysticks and other compatible accessories can also be connected wirelessly to the set-top box. Meanwhile, the wired interfaces on the model include a USB 2.0 port, an HDMI socket, and a 3.5mm audio jack.

4K HDR

Inside the compact smart device case, there's powerful "hardware": an Amlogic S905L processor with four Cortex-A53 computing cores, 2 GB of RAM, and 8 GB of internal memory for storing user data. The "setup" ensures high-definition video playback (in 4K format) with a frame rate of up to 60 fps, and also in an extended dynamic range (HDR technology). Lags and delays in displaying 4K video on the television screen are eliminated.

Younger Brother

Combining so many "goodies" in one package, the set-top box is also reasonably priced. And if someone finds its price tag high, they can consider the younger version of the model, Xiaomi Mi Box 4c. It differs from the classic "four" by its black color (as opposed to white), reduced RAM volume (1 GB), lack of a Bluetooth module, and support for Dolby + DTS audio technology.
