Verb: To combine two or more independent signals into one transmission channel Noun: The combined digital signals transmitted on one satellite transponder
A multiplex is a cinema complex with six or more screens. a cinema that has several different rooms in which it can show films (adjective, , from multi- ( MULTI-) + -plex ). having many different parts
The simultaneous recording or transmission of multiple data Cylindrical holograms are often called "multiplex," although this is not always technically the case
Simultaneous transmission of two or more signals on a common carrier wave The three types of multiplex are called time division, frequency division, and phase division
many and varied; having many features or forms; "manifold reasons"; "our manifold failings"; "manifold intelligence"; "the multiplex opportunities in high technology"
a multiplex is where two or more routes overlap on the same stretch of pavement; sometimes a dually signed road is referred to as a duplex and three routes that share the same stretch of pavement are referred to as a triplex The FHWA prefers the term overlap in these instances
Where two road numbers share the same road In Britain, only one road number may be shown on signs at once so one road must be 'dominant' over the other in a multiplex - ie, one must be signed and the other invisible A good example is the M60 Manchester Ring Road, which multiplexes with the M62 in the north-west Road signs show the road as "M60 (M62)", with the M60 being 'dominant'
Using one carier to send more than one signal In video multiplexers, achieving this by sending a different camera's output in each successive field or frame of a video signal, in a form that can later be retrieved as single camera pictures
When a broadcaster provides more than one service (for example, two multichannel SDTV services, or a simultaneous SDTV and HDTV transmission, or a television program and simultaneous datacasting) it is necessary to mix or multiplex these services into one broadcast transmission This is done electronically through a multiplexer The receiver then separates out the various signals to reproduce the original material transmitted, in different forms
The division of a single transmission medium into multiple logical channels supporting many simultaneous sessions For example, one network may have simultaneous FTP, telnet, rlogin, and SMTP connections, all going at the same time
To transmit two or more messages or message streams on a single channel, typically through the use of frequency-division multiplexing, time division multiplexing, or statistical time division multiplexing
Combining multiple signals (analog or digital) for transmission over a single line or channel Multiplexing often combines several low-speed signals for transmission over a single high-speed connection
Combining signals of multiple channels into one channel This process provides multiple users with access to a single conductor or medium by transmitting in multiple distinct frequency bands (frequency division multiplexing, or FDM) or by assigning the same channel to different users at different times (time division multiplexing, or TDM)
