Android TV box
A small device that connects to a screen over HDMI and runs Android apps, turning an ordinary TV into a signage screen.
An Android TV box is a small device that plugs into a television's HDMI input and runs the Android operating system. It is one of the most affordable ways to turn a screen without smart features, or with outdated software, into a signage screen that can run apps. Televisions with Android TV or Google TV built in work the same way.
When choosing a box for signage, check its storage, its network connection (wired if possible), how it copes with heat and whether it switches itself back on after a power cut.
The MIA Player app
MIA offers the MIA Player app (APK) for Android TVs and boxes; an up-to-date WebView on the device is recommended. The app starts automatically when the device boots, runs full screen and keeps the screen awake. It stores videos and images on the device and keeps a copy of the player page, so it starts playing after a power cut even if the server is unreachable. It updates itself from your own server. See the guide to Android TV digital signage setup.
