Well you have to be comparing apples with apples.
If you are feeding your 4 FE's from a myth BE, then there is no HDCP in 
the stream.  -> no problem,

If you are plugging some form of network receiver (Chromecast or FireTV 
stick) into a post-circa-2005 TV, then any HDCP in the stream will be 
confirmed/handshaked with the TV, as *they* are HDCP compliant.
You would have to plug the stick into something NOT HDCP compliant, to 
determine that status, (check against a compliant box) then feed it 
through the hub to the non-compliant tv.

I think you will find that the net has been cast rather tightly and that 
HDMI splitters available in North America are all HDCP compliant on both 
sides of the box..

I have NO idea about the compliance characteristics of an XBOX One, but 
if it is not compliant it will be a useful state-tester.

Throughout I am assuming 1080 HDMI to HDMI connections, not Component 
nor downgraded 480p SD outputs.
