Video Routers are used for transporting video signals from inputs to outputs.
Inputs and Outputs
The number of inputs and outputs varies dramatically. The way routers are described is normally number of inputs by number of outputs e.g. 2x1, 256x256.
Signals
The type of signals transported can be anything from analogue composite video signals PAL, NTSC. Analogue components, Digital: SDI, HD-SDI. Also Broadband routers can route more than one signal type of Digital video eg SDI and HD-SDI.
Crosspoints
Because any of the inputs can be routed to any output, the internal arrangement of the router is arranged as a number of crosspoints which can be activated to pass the corresponding signal to the desired output.
Control Panels
Many type of control panels can be use to control the video router.
