Apple today released tvOS 17, the latest version of the tvOS operating system that runs on the Apple TV 4K models and the Apple TV HD.
tvOS 17 can be downloaded using the Settings app on the Apple TV. Go to System > Software Update to get the new software. Apple TV owners who have automatic software updates activated will be upgraded to tvOS 17 automatically.
In tvOS 17, Apple has added a FaceTime app for FaceTime calls on a larger screen. The feature works through an iPhone or iPad running iOS 17/iPadOS 17, with the iOS device serving as the camera and the TV serving as the display. With a Split View option, you can place your FaceTime call on one side of the TV and a TV show or game on the other side for SharePlay experiences.
