What is a matrix switcher?
A video matrix switcher is an electronic device capable of interconnecting many components in any desired combination. This includes devices like a VCR's input and the same VCR's output. This type of hook up makes it easy to use the same VCR for recording or play back. This switch allows
any one of the inputs to be switched to any one or all of the outputs. Matrix switchers route multiple audio and video sources (input signals) to multiple audio and video destinations (output signals). Input sources include computers, cameras, DVD players, etc. Destinations include projectors, monitors, and computers etc. Matrix switchers route any input to any combination of outputs. Different matrix switchers can route different signals, such as composite video, S-Video, stereo audio and mono audio. Matrix switchers are used in corporate boardrooms, classrooms, restaurants, home theaters, and video conference rooms.

Another definition.
Simultaneous access to multiple sources is what differentiates a matrix switch from a simple switch which would only allow one source to be viewed by multiple zones. A matrix switcher allows multiple users to access signals from multiple source components. This type of switching is ideal for whole-house application. For example, it may be necessary to view the DVD player in the bedroom while, at the same time, viewing the satellite receiver in the home theater. Matrix switchers are perfect for this application, as it allows multiple sources to be accessed by multiple users simultaneously.

Two devices with video inputs. Such as Monitors, DVR's, Televisions, Modulators, etc.
Two rotary selector switches with 3 positions each.2 Video
The above diagram shows a schematic of a simple manual video matrix switcher.
There are 3 video inputs (VCR, camera, satellite TV) and 2 video outputs connected to two TVs. Each TV is associated with a rotary switch within the video matrix switcher. Both switches can select the same input or
different inputs without disturbing any signals. Normally connecting two TVs to the same camera will degrade the video signal to each TV. The video matrix switcher avoids this by using video amplifiers. No signal will degrade by this method even if 15 monitors are all viewing the same source of video. There are more details to this device, but with some working knowledge of the interior it is easy to hook up and use a manual video matrix switcher.
