Abstract:
1. A method of routing that distributes a plurality of sources of at least one of analogue audio, digital audio, and video data to a plurality of destinations, the method comprising: dividing source data inputs of a plurality of input modules into a plurality of groups of source data inputs; receiving source data at the source data inputs; sending, from each of the plurality of input modules, input signals corresponding to the source data received at each of the plurality of groups of source data inputs to at least one of a plurality of main crosspoint modules with every main crosspoint module receiving one group of corresponding input signals from every input module and receiving only corresponding input signals in that group; sending, from each of the plurality of input modules, input signals corresponding to the source data received at a selected one of the plurality of groups of source data inputs to a redundant crosspoint module; receiving, at a plurality of output modules, output signals from the plurality of main crosspoint modules and output signals from the redundant crosspoint module; supplying, via the plurality of output modules at a plurality of destination data outputs, destination data corresponding to the output signals from the plurality of main crosspoint modules: and controlling, at the plurality of main crosspoint modules and the redundant crosspoint module, routing of the input signals corresponding to the source data received at each of the plurality of groups of source data inputs from the plurality of input modules to the output modules.
