1. A signal routing device comprising:
a compact compliant router with plural input ports and plural output ports for routing video signals; the input ports and the output ports for exchanging serial digital interface (SDI) compliant signals; the router including a main crosspoint switch for interconnecting input and output ports during normal mode operations; the router including a backup crosspoint switch for interconnecting input and output ports during backup mode operations; the router configured to maintain the backup crosspoint switch in a relatively thermally cold state as compared to the main crosspoint switch when the router is interconnecting input and output ports during the normal operating mode; the router configured to increase the supply of electric power to the backup crosspoint switch upon a main crosspoint switch malfunction; and, upon a main crosspoint switch malfunction, the router configured to substitute switching functions of the backup crosspoint switch for the failed switching functions of the main crosspoint switch.
