The biggest tweak in the next-gen Apple TV operating system is platform-wide picture-in-picture. This means that users can continue playing Apple TV games or using fitness apps while also screening a movie, watching live sports or keeping tabs on the news.
HomeKit will now be baked more deeply into the Apple TV interface. That will make it easier to do things like check in on HomeKit-supported smart cameras or video doorbells in full screen on Apple TV.
In addition, Apple Arcade on Apple TV will support multiple users. That means Apple TV will be able to remember exactly where players left off with games. Apple additionally said Apple TV can now be paired with Xbox Elite Series 2 and Xbox Adaptive controllers.
Another update is the ability to support 4K streaming of video from the Photos app on iOS or iPad OS. YouTube will be capable of streaming in 4K on Apple TV, too.
Finally, Apple said its streaming video service will arrive on Vizio and Sony smart TVs later in 2020. According to Apple, this will make Apple TV+ available for close to 1 billion users, split between iOS, streaming media players and smart TVs.
