The version of the TV-optimized operating system builds on the many new features introduced for Android 11, but also adds performance and privacy improvements, new features tailored for the TV, and updated developer tools.
One of the notable TV-related improvements in Android 11 includes HDMI 2.1’s Auto Low Latency Mode (ALLM) which allows the latency setting to be automatically established depending on the applications, as for instance, many games require the lowest possible latency, while it’s not really an issue for movies and videos.
Android 11 on Android TV also adds low latency media decoding, a new Tuner Framework with updated Media CAS support, extensions to the HAL implementation of HDMI CEC, extended gamepad support, silent boot mode for system updates, inactivity prompts, and OEM configurable wake keys. A new framework functionality for managing System LEDs and physical microphone mute buttons also facilitate integrations for far-field microphone enabled devices.
App developers may also find the new version of Android TV to be easier to work with thanks to the addition of a test harness mode on Android TV and Play Store support in the Android TV Emulator.
Android 11 is already available on ADT-3 devices today, and Android TV OEMs are expected to upgrade existing devices or launch new Android 11 TV boxes over the coming months. More details may be found on the developer page.
