Abstract: When switching sources, resolutions or refresh rates in a video distribution network, switching times are reduced by maintaining video lock and security authentication between a video switcher and a video sink. The scaler maintains video lock and security authentication by continuing to generate video timing data during switching events. The scaler also facilitates an aesthetically pleasing transition by generating image content data prior to and after the switching event.

Abstract: A master Ethernet bridge for use in an Ethernet network that includes a master central processing unit and associated master Ethernet switch, and one or more slave central processing units, each having an associated slave Ethernet switch, each of the associated slave Ethernet switches connected to a plurality of input/output ports, and wherein each of the plurality of ports is assigned a respective port number, each of the ports being connected to one of the one or more of the cascaded Ethernet devices, and wherein each of the master CPU and slave CPUs includes memory that contains a program that embodies a plurality of Ethernet functions adapted to substantially prevent re-routing of Ethernet commands by providing a mapping function that correlates the plurality of ports to respective ones of the one or more slave CPU and slave Ethernet switch.
