Android 12 til TV-enheder er frigivet, melder Google, men det kommer til at tage noget tid før det rammer din Android TV- eller Google TV-enhed. Her er de nye funktioner.
Nyhederne i Android TV 12
Den vigtigste nye funktion i Android 12 til TV er 'refresh rate switching', der sikrer videoafspilning af 24fps, 25fps, 50fps, 60fps uden hak. De individuelle streamingtjenester skal dog også sikre, at deres app understøtter det.
- "Vi har tilføjet yderligere tilpasninger i Android 12 med henblik på at forbedre oplevelsen og kompatibiliteten på TV-enheder. Nogle af højdepunkterne, der kommer med Android 12 til TV, er forbedringer af medieafspilning, mere raffinerede brugerfladefunktioner samt forbedringer af privatlivets fred og sikkerhed. Derudover introducerer vi bedre standardunderstøttelse og forbedringer til HDMI og tunere," sagde Google.
Android 12 åbner konkret for brugerflade i 4K-opløsning (1080p i dag) og andre brugerflade-justeringer såsom sløring/fokus, indikatorer for mikrofon og kamera så brugeren ved om enheden kigger/lytter med samt understøttelse af HDMI CEC 2.0 så tilsluttede HDMI-enheder bedre kan snakke sammen.

Chromecast, Nvidia Shield, TV?
Der er frigivet særskilte versioner af Android 12 til hhv. Android TV og Google TV. Den nye Chromecast (med Google TV) virker som en oplagt kandidat til at få Android 12, men Google har ikke kommenteret på planerne. Chromecast kører stadig Android 10.
Det står i skarp kontrast til Apple TV, som får nyeste version af tvOS med det samme.
Vi forventer heller ikke, at Nvidia Shield (kører stadig Android 9) eller TV-skærme fra Sony, Philips, TCL, Xiaomi og andre mærker får Android 12 i nærmeste fremtid. Nye funktioner kan dog introduceres uden at Android-systemet opdateres, f.eks. brugerprofiler og huskelister. Herudover åbner Google for 'Play as you download' i app-butikken, så brugerne kan starte nye spil før hele pakken er downloadet.
På nuværende tidspunkt kan Android 12 TV kun installeres på Googles udviklerboks (ADT-3).
Android 12 til TV – nye funktioner
| Med Googles egne ord:
Media
At the heart of the TV experience is beautiful and seamless media playback. In the US, users are spending well over 4 hours a day watching media on TV, and are always asking for the highest resolution playback possible. With Android 12, we are releasing three new features to better support ever-improving picture quality.
- Refresh Rate Switching Settings: For a smoother viewing experience, Android 12 now supports seamless and non-seamless refresh rate switching. Apps can now integrate these settings for playback of content at optimal frame rates. The Match Content Frame Rate user setting has been added to allow users to control this feature, and apps can call Display.getMode to know if a user’s device supports seamless rate switching.
- Better display mode reporting: We are improving how TV devices report display modes and making hotplugging behavior more consistent. App developers no longer need to use workarounds for accurately detecting display modes or for handling HDMI hotplug events.
- Tunnel Mode Updates: Updates to Android’s tunnel mode are making it even easier for app developers to support consistent and efficient playback across devices by reducing media processing overhead in the Android Framework.
User Interface
A beautiful media experience needs an equally stunning user interface to match. Android TV brings two new additions to the UI that help developers provide users with a richer visual experience on high performance devices.
- Background blurs: Background blurring using RenderEffect (for in-app blurs) and WindowManager (for cross-window blurs) can now be used to easily enhance the visual separation of different UI layers.

- 4K UI support: For added visual fidelity, Android TV OS now officially supports UI rendering at 4k resolution on compatible devices. 4K UI resolution can be tested in the upcoming Android 12 emulator for TV to allow app developers to prepare their app for devices with the higher resolution.
Privacy and Security
With Android 12, we’re continuing to focus on giving users more transparency and control while keeping their devices and data secure. Beta 3 for TV includes many of the new privacy features from the Android framework.
- Microphone and camera indicators: Users will now see any time apps are accessing the microphone or camera by showing an indicator on the TV screen. For better visibility of recent app accesses to microphone and camera, users can visit their privacy settings on TV.

- Microphone and camera toggles: Two new global privacy settings are now available, allowing the user to easily toggle access to the microphone or camera. When those toggles are disabled, apps will be unable to access microphone audio and camera video.
