Patent ID: 7797711

Claim:
A method of controlling signals within an audio/video device, said method comprising: automatically detecting peripheral devices coupled to source nodes and target nodes of said audio/video device; generating a display comprising a graphical user interface (GUI) comprising a plurality of displayed GUI elements that represent said source nodes and said target nodes and connection paths between said source nodes and said target nodes, wherein said plurality of displayed GUI elements includes a first subset containing only said source nodes that are coupled to said peripheral devices and wherein said plurality of displayed GUI elements also includes a second subset containing only said target nodes that are coupled to said peripheral devices, wherein said plurality of displayed GUI elements also includes a subset of said connection paths containing only said connection paths that are possible between said first subset of source nodes and said second subset of target nodes, said GUI further comprising a first GUI element useful for displaying a first video signal associated with a first source node of said source nodes, wherein said first video signal is displayed in said first GUI element; and routing a signal between a first node and a second node by manipulating circuitry within said audio/video device in response to user input.
