Does anyone know why we do not hear about multiplexers outside Poland. Thanx
We do. Most European countries use them in one form of the other. In PL, people like to talk about technical details whether necessary or not. You'll notice this in Media Saturn when people are firing lists of pointless questions to the sales assistant when you just want to buy something and go.
It's just a system combining several input systems into one output Basically transmitting data (either Multiplex TV or, phone called or internet etc) through one cable or channel rather than many. Which makes it cheaper.
At the moment they're setting up a multiplex TV platform - not unlike the UK's digital free-to-air channels. There's some very minor but loud controversy about allocating slots because one particular TV station wants a slot without meeting the financial conditions.
