From Wiki:

An invention is a unique or novel device, method, composition, idea or process.

This is a novel method and process. Sure, anyone could imagine putting something on one screen to another, but apparently no one came up with an implementation until 2011.

The patent in question (the articles suggest 3 patents, but they’re all basically the same): patents.google.com/patent/US8356251

So it’s a process that’s a little more involved than just “display this video on that screen”.
