MPEG-2 Multiplexer

A hardware device or software algorithm that multiplexes different MPEG-2 Elementary Streams into a MPEG-2 Transport Stream for transportation over Networks or a MPEG-2 Program Stream for Storage on harddisks or DVDs.

The MPEG-2 Demultiplexer reverses this process on the receiver side; from the TS, the different MPEG-2 Elementary Streams (Audio, Video, Subtitle, Teletext etc.) are separated out, and thereby made ready to be processed by the different decoders.
