Abstract
The embodiments described herein provide a video router with integrated control layers and a method of operating the same. The video router includes line cards and fabric cards coupled to a controller communication network. The line cards and fabric cards include crosspoint switches and card controllers. Each card controller controls the operation of the corresponding crosspoint switches. Each crosspoint switch includes a plurality of input switch terminals and output switch terminals coupled to a backplane, providing signal communication paths between the line and fabric cards. The configuration of at least some of the crosspoint switches may be controlled by the controller on the same card or on other cards. The video router may include a switch configuration table to track the coupling of input and output terminals through each of the cross-point switches.
