In the context of Mythtv "Set Top Box" (or STB) refers to a box provided by the
supplier of your program content: Cable, satellite, Internet, or in some parts
of the world Digital over-the air broadcasts.
We do not usually use the term STB for the device which takes programming from
the network and displays it on your TV. That would be a "Front End". This could
drive a TV or projector. It can be a standard uPnP client but it would more
usually be a small PC running Mythtv software. It doesn't have to be a big box,
as others here have tried to explain to you.
Mythtv works as a "pull" system. The back end (or back ends) contain tuners and
other interfaces capable of receiving video and other inputs from many sources,
the data from which is *always* stored on disc. Each front end then accesses the
data files through a menu system simple enough for most members of any household
What you seem to be describing is a "push" system, where *all* data streams are
put on the wire at once and the client chooses which stream to read. This is the
way Cable works, thinking about it. This is inefficient, especially in network
terms. Why broadcast streams if no-one is receiving them? The Mythtv way is much
