The main interface of mainstream set-top boxes (such as Xiaomi Box, Dangbei, etc.) is divided into modules such as movie and television, applications, and settings. Use the direction keys on the remote control to select and the confirmation key to enter. Some models support voice control (press and hold the microphone button on the remote control).

| cast screen | Make sure that the mobile phone and the set-top box are on the same network, open the video APP and click the "Cast Screen" icon | 
| Install app | Download the APK file via USB flash drive or built-in app store | 
| Image quality adjustment | Go to Settings-Display-Resolution and select 4K 60Hz (requires TV support) | 
3. Solutions to high-frequency problems
1. The remote control fails
Try changing the battery or re-pairing (the Bluetooth remote control requires long pressing the Home + menu button for 5 seconds). The infrared remote control needs to be pointed at the set-top box receiver.
2. Network lag
Check the Wi-Fi signal strength. It is recommended to use the 5GHz band or connect the network cable directly. Clear the cache in settings or restart the router.
3. Interface unresponsive
Press and hold the power button of the set-top box to force restart, or enter recovery mode to reset the system (different models operate differently, please refer to the manual).
4. Advanced skills and trends
Popular methods recently include: building a home audio and video library through Kodi, using the DLNA protocol to play across devices, and connecting an external game controller to transform into a game console. In addition, AI voice interaction and cloud gaming have become key features promoted by manufacturers.
