Multiplexing, a popular networking technique

- May 27, 2017 -

Multiplexing (or muxing) is a way of sending multiple signals or streams of information over a communications link at the same time in the form of a single, complex signal; the receiver recovers the separate signals, a process called demultiplexing (or demuxing).

In Electronic Communications, the two basic forms of Multiplexing are Time Division Multiplexing (TDM) and Frequency Division Multiplexing (FDM).

In Time Division Multiplexing, Transmission Time on a Single Channel is divided into non-overlapped Time Slots. Data Streams from different Sources are divided into Units with same size and interleaved successively into the Time Slots.

In Frequency Division Multiplexing, Data Streams are carried simultaneously on the same Transmission medium by allocating to each of them a different Frequency Band within the Bandwidth of the Single Channel.

Multiplexing is done by an equipment called Multiplexer (MUX). It is placed at the Transmitting End of the communication link. DIBSYS DCM700 is an ideal solution for multiplexing, scrambling of MPEG streams which provide a cost effective, versatile and efficient for delivering digital TV content over IP networks that Integrates up to 16 separate IP address or Ports and De-encapsulates and Routes Any or All Selected Transport Streams via GbE IP Inputs Port.
