Hi, embedded developer here who spends a considerable amount of time writing firmware for "bare metal" systems with "no 
OS".

I have fairly high confidence that what Mike was referring to was "whatever base level software ships on the doohickey 
and provides the underlying infrastructure for the user-visible 'apps' that move media from the Internet to the 
monitor".  Mike, please correct me if I'm wrong.

In that context, it doesn't really matter what the box is running.  Could be Linux, could be Windows, could be QNX, 
could be a "while(1) scheduler" and some embedded IP stack.  Anything smart enough to fall under the purview of the 
discussion we're having regarding "streaming services" is going to have some sort of "OS-like" infrastructure that 
could, if desired, centrally handle these kinds of alerts so that every single streaming "app" doesn't have to concern 
itself with that.

I can't fathom somebody making a "media streaming device" these days without that kind of separation of duties 
internally regardless of what actually runs underneath the user-visible application.  It's not that you couldn't but 
rather that you wouldn't.
