The developer / hacker Steven Troughton-Smith recently showed us how iOS could work with windows on the iPad, and now decided to play with the tvOS.
Wrote a PiP setup for my TV app. Love how it works – totally fits on tvOS. Not sure why not built-in yet ? https://t.co/fyE6zruzkA

In the video above, it shows an internal solution that he created to watch his cable TV via Apple TV, which in itself is too much, but also incorporating a Picture-in-Picture (PiP) in it. IOS 9 on iPads already has that, so it's not hard to imagine it coming to tvOS as well.
Who knows soon, n Apple? ?
