Patent ID: 8310264

Claim:
A method for configuring a combinational switching matrix, comprising the steps of: setting a first switching module and a second switching module such that the first switching module includes a plurality of first input ports, first output ports and first switching devices, and the second switching module includes a plurality of second input ports, second output ports and second switching devices, wherein the first switching devices are configured to open and close the electrical connection between the first input ports and the first output ports, and the second switching devices are configured to open and close the electrical connection between the second input ports and the second output ports; coupling at least one of the first output ports with at least one of the second input ports to form the combinational switching matrix including a plurality of input terminals, output terminals and virtual switching devices representing the connection states between the input terminals and the output terminals; building a connection mapping table by considering the coupling relationship between the first output ports and the second input ports, with the connection mapping table describing the relationship between the virtual switching devices, the first switching devices and the second switching devices; and displaying a channel switching interface including the input terminals, the output terminals and a plurality of virtual switching devices.
