Multiplexors or MUXs, as they are often called, are devices that combine signals from various sources such as PBX (Private Branch Exchange), asynchronous terminals or a bridge connected to a WAN. A multiplexor transmits these signals as a single data stream over a digital line. Multiplexors conserve bandwidth.
A device or component which steers one of several input signals to its output as directed by a control input. Also spelled Multiplexer.
1. A device that takes several input signals and combines them into a single output signal in such a manner that each of the input signals can be recovered. 2. A device capable of interleaving the events of two or more activities or capable of distributing the events of an interleaved sequence to the respective activities.
A device that combines input signals from many computers and sends the combined signal along the communication channel.
A communications device that collects data from a number of low-speed devices, then transmits the combined data over a single communications channel. At the destination, it separates the signals for processing.
A device that accepts video signals from a number of cameras and encodes them into one signal that is recorded on a digital recorder or VCR. The multiplexor also decodes the recording, so it can play back motion video from one camera at a time or several cameras all at once to one monitor. Many multiplexors also display several camera views at a time on a monitor while sending images to a recorder.
A device that supports multiple readers by checking each one in accordance with a scheduling scheme. Back to the alphabetical list at the top.
a device that has several data inputs, and selects one of them to appear on the output stream
a hardware device that has one input and multiple outputs
an electronic device that allows a single communications channel to simultaneously carry data transmissions from many sources
A device that can send several signals over a single line. They are then separated by a similar device at the other end of the link. This can be done in a variety of ways: time division multiplexing, frequency division multiplexing and statistical multiplexing. Multiplexers are also becoming increasingly efficient in terms of data compression, error correction, transmission speed and multi-drop capabilities.
This is a device used to interleave multiple inputs (data from an Ethernet LAN, Voice from a PBX, Video Codec, etc.) to allow the inputs to be carried over a single high speed facility, like a T1 circuit.
A device that very quickly switches between cameras therefore reducing the dwell time on each camera as is normally associated with conventional switchers. Cameras can be viewed on screen one at a time or multiple. Simplex multiplexors record only what is being viewed on the screen by the user.
Same as above except duplex multiplexors record all cameras regardless of what the user views on the screen.
A device which enables several different signals to be sent down the same line. Sometimes referred to as a "mux".
A device that can accept a number of camera inputs and almost simultaneously display them on a single monitor and/or record them. Multixplexers can also be used to transmit multiple cameras over the same transmission medium. more
A device used for division of a transmission facility into two or more subchannels, either by splitting the frequency band into narrower bands (frequency division) or by allotting a common channel to several different transmitting devices one at a time (time division).
