How to set up broadcast from phone to tv box?

Question

Android

There is a Beelink set-top box connected to the TV via HDMI and a Huawei smartphone.
How can I start broadcasting from the smartphone screen to the TV box?
Is it also possible to broadcast the laptop screen to the set-top box?
All hardware is in the same wi-fi network.

Answer 1

If the set-top box supports something like modern Miracast implementations. Windows 10 has built-in support, but is physically dependent on the chipset.

Answer 2

I have a Beelink R89 and a Xiaomi phone.
A similar feature worked on stock firmware with the Press Center application.
If the TV fox is on the Rockchip process, then the RKRemoteControlGeneralCastV2.0.4.apk application is installed on the phone and you broadcast anything from it to the set-top box.
