Multiplex (TV)

Multiplex (TV)

A multiplex or mux (called virtual sub-channel in the United States and Canada, and bouquet in France) is a group of TV channels that are mixed (multiplexed) for broadcast over a digital TV channel and separated out again (demultiplexed) by the receiver. There are two different types of multiplexes, which are closely related but not identical.

In the UK a multiplex (usually abbreviated mux) is a band of fixed width containing a number of channels. In the US, the same arrangement is often described as a channel with virtual sub-channels.
