We have a couple Samsung Smart TVs at the house, and I was just experimenting last night with "casting" -- in this case from
desktop computer to one of the TVs.
The
current Samsung desktop/Android/Apple app -- used to be Allshare, then Allshare Plav, then Live something, then Allshare Play again, something like that -- is Smart View. Fire up Smart View on the serving device, connect both server and TV to the same network, select media on the server, play.
Didn't check all options completely, but it looks like the same instructions
work whether the "server" is a Windows/iOS/Linux device, or an Android tablet or phone, or an iThing.
I'm thinking this would mean media could be downloaded in advance or streamed live, and "the same network" would mean an onboard router, a hotspot created by a smartphone, a hotspot created by something like Win 10 (incorporated), or a virtual hotspot created with something like Connectify.
The TVs already have apps for stuff like Netflix, Hulu, many others I didn't recognize... so I guess some of that "casting" wouldn't even really be necessary... assuming sufficient bandwidth, no pesky buffering, etc.
