Apple TV tvOS 11 to get multi-user, picture-in-picture features

It will be possible, sources say, to set up multiple users for a single Apple TV box. Each user would have access to his or her own Apple Music, iCloud, and iTunes content. […] Apple TV will supposedly also get picture-in-picture or PIP support in tvOS 11. This feature is pretty much a staple of many modern entertainment systems, be it smart TVs, set-top boxes, or even gaming consoles. – JC Torres, SlashGear
