Abstract:
A signal switching method for use with a routing switcher having plural input terminals and plural output terminals in which a cross point phantom identification name is assigned to each combination of one of said input terminals and one of each of said output terminals, each of said combinations of input and output terminals being represented by a particular cross point phantom identification name being switched to by the operation of a source operation switch associated with said corresponding input terminal and a destination operation switch associated with said corresponding output terminal, the method comprising the steps of:storing in memory as cross point identification data said cross point identification name associated with a desired input terminal;selecting said source operation switch corresponding to said input terminal of said cross point identification data;determining whether said cross point identification data includes an associated output terminal;if said cross point identification data includes an associated output terminal, selecting said destination operation switch corresponding to said output terminal of said cross point identification data;if said cross point identification data does not include an associated output terminal, providing said associated output terminal, and selecting said destination operation switch corresponding to said provided output terminal; andswitching said routing switch to connect said input and output terminal through the operation of said associated respective source and destination operation switches.
