Play a video or music on the TV with plex/web or plex android / iphone

When I'm at home and connected to wifi with my Samsung Galaxy S3 phone, I can play a video on my phone or ask him to play on the television.

 

(At home I have a Sony home cinema, a television and two computers connected to my internet router wifi.)

 

Would be nice to have the same function in Plex / web -> When I'm watching a movie with my computer or my phone via Plex on my local network, I'd like to click a button to send video to my television (or home cinema)


It would be really great to be able to do that with plex / Plex web or android or iphone.

 

What you say guys?
