Although strangely not mentioned in Apple's WWDC keynote, tvOS 13 Beta 2 has a nice surprise: support for picture-in-picture video playback.
You can now watch shows from the Apple TV app while you multitask the rest of the world's operating system. Just like the iPad, Apple TV users can play the video in a thumbnail window as they navigate the rest of the operating system.

Picture-in-Picture was first introduced in iOS 9 as a multitasking feature for the iPad. It now seems to be on the way to the big screen.
Users can start a video in full-screen mode, then switch between apps and continue to watch the video being played in a thumbnail. The controls that overlay the video allow you to go straight back to the app or stop playing the video.
tvOS 13 includes several new changes to the Apple TV experience, including a redesigned home screen with a new Top Shelf experience. Apps can display videos in the background of the home screen so that users can preview the content before they dive into an app.
tvOS 13 also provides support for multiple users, so families will be able to have separate Watch Next queues and not interfere with each other's recommendations.
Finally, in cooperation with the BBC, tvOS 13 will feature a series of new Under the Sea screensavers.
