Send a video to one room.
This is the console a medical assistant opens in the corridor. Pick a field of care, pick the piece, choose the room, send. The room shows it and puts itself back on the playlist when it is done.
Nothing here leaves your browser. There is no account, no server call and no real television at the other end. The countdowns are the real rule — a push runs its own length plus a minute of grace, and never longer than ten minutes.
Send content to a room
Fifteen screens in one building. Whatever you send moves exactly one of them.
The same two rules the real console follows.
One room moves, the rest do not
A push names a single screen. The other fourteen keep working their way through the everyday playlist, in step with each other, having been told nothing.
It ends without anybody ending it
Two independent things clear a room: the video finishing, and the deadline the push was created with. A room does not sit on a stale video because somebody was called away.
