1. A router control system for routing data streams from a plurality of input ports to a plurality of output ports using at least one video router, the router control system being configured to:
transmit one or more router configuration signals to one or more video routers, the one or more router configuration signals comprising instructions to selectively configure the one or more video routers,
wherein each video router comprises:
a backplane including a plurality of backplane connections,
at least one line card, the line card comprising:
a plurality of input ports and output ports, each input port and output port being coupled to a respective external signal through the backplane, and
a line card cross-point switch having a plurality of input switch terminals and a plurality of output switch terminals, wherein a first plurality of input and output switch terminals are coupled to a respective plurality of input and output ports and a second plurality of input and output switch terminals are coupled to a respective plurality of backplane connections, and
at least one fabric card, each fabric card comprising:
a fabric card cross-point switch having a plurality of input switch terminals and a plurality of output switch terminals, wherein the plurality of input and output switch terminals are coupled to a respective plurality of backplane connections, and
wherein, for each of the one or more video routers, the one or more configuration signals are configured to:
instruct selective coupling of one or more input switch terminals of a corresponding cross-point switch of one or more line or fabric card to one or more corresponding output switch terminals, and
selectively control the operation of the corresponding one or more line or fabric card.
