View photo memories on Apple TV
The Memories category in the Photos app 
automatically arranges photos and videos you haven’t seen or thought about in a while. Trips, events and moments are presented in a short movie you can watch on the big screen.
To get memories on your Apple TV, you need to have photos and videos on another iOS device, iPadOS device or Mac linked to the same iCloud Photos account. The best memories created on those devices will automatically become available on your Apple TV.
You can’t create or edit memories on Apple TV, but you can see all the photos and videos in a timeline and skip to your favourite photos or videos during playback.
