Android application package for 电视家 (Dianshijia), a Chinese live TV streaming app, version 2.13.28, labelled as an ad-free VIP build intended for older television sets and set-top boxes. The 13.8 MB APK installs directly on Android TV boxes or smart TVs via USB stick or sideloading. It is not repair data and contains no schematic or firmware. Modified builds of this kind come from unofficial sources, so scan the package before installing it on a customer device and expect it to stop working when the service changes."}
