Video router
A video router , also known as a video matrix switch . The number of inputs and outputs varies dramatically. Routers are normally described by the number of inputs by number of outputs 256x256, 576x1152. Some video routers, by the use of additional drop-in cards, allow the system to be expanded for more inputs or outputs, or to support other formats. Because many of the sources can be routed to any destination, the internal arrangement of the router is arranged as a number of crosspoints which can be activated to pass the corresponding source signal to the desired destination. This architecture has guaranteed bandwidth and is non-blocking.
