User:Sammi Brie/Multiplexing in digital broadcasting

Multiplexing refers to the ability to broadcast more than one program stream of data, audio, or video in the same transmission, which may be referred to as a multiplex (abbreviated "mux"). This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called "multicasting".

The ability to broadcast multiple services in channel allocations that supported just one service under analog broadcasting has led to the creation of new TV services and radio stations.
