Abstract: Disclosed herein are system controllers and larger systems incorporating such that can dynamically prioritize critical digital video data streams traveling across a network backbone over other non-priority video data and make the selection of which video streams are to be connected and prioritized through real-time use of video control panel equipment. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.

Abstract: A communication network for providing communication between multiple sources and multiple destinations includes a source selector (34; 70, 72; 90, 98) having a plurality of input terminals (22) for connection to respective sources (30), at least one output terminal (20; 100), and crosspoint elements (38; 80, 82; 92, 98) for connecting any selected set of the input terminals to the output terminal. A destination selector (18; 100) has at least one input terminal (20) connected to the output terminal of the source selector, a plurality of output terminals (24) for connection to respective destinations (30), and crosspoint elements (28; 102) for connecting the input terminal of the destination selector to any selected set of the output terminals of the destination selector.
