A combination of video switch and a video splitter, the video matrix switcher is a device that allows multiple video and audio sources to be routed and switched between multiple video displays and speakers. Some or all videos from the sources can be routed to either some or all of the display devices. Since any combination of input can be connected any combination of output, the result is a matrix like pattern of interconnection possibilities, thereby giving the name to the switching device. Available in configurations ranging in sizes as small as 2x2 units to as large as 32x16, these units can also be cascaded to achieve an even greater configuration.

There are several types of these switches available depending upon the type of video they support. Some common models categorized on this basis are component matrix switch, composite matrix, VGA matrix switch, DVI matrix switch, s-video matrix, VGA audio/video matrix s and Cat5 audio video switch. While some of these units use VGA cables for securing connections, other use either Cat5 cables or DVI cables for the same. All these models operate on simple plug and play functionality and do not require any additional software or device drivers for operation. Control is typically done via push buttons in front of the matrix but high end models also use RS232 or Infra red remote control for the same.

An easy to use hardware device for complex configurations, the component matrix is available in standalone desktop versions or in rack mountable units. This model is available in 4x2, 4x4, 6X4 and 8x8 combination and some variants have the option to switch audio along with video. A maximum bandwidth of 325 MHz and video resolutions of 1080p are supported by these devices. The greatest advantage of this device is that it eliminates the need to move around video input and output cables. Designed to work with video equipment that has proper connections such as Cable and Satellite receivers, Computers, Video Scalers, DVD players, VCRs and so on, these switches also have regulatory approvals from CE and FCC. These are also used for digital signage hardware applications.

The LEDs on the front of the component matrix switch, indicate the connection status. Due to these features along with the ability to route video and audio from multiple sources to multiple displays in any combination, the video matrix switches are used extensively in entertainment facilities, commercial and business establishments, government, training and surveillance industries.
