  • Router and method of routing with redundancy
    Patent number: 8631172
    Abstract: A method of routing audio or video data. A plurality of source data inputs to input modules are divided into groups and main crosspoint modules receive one group from every input module, and destination data outputs from output modules are divided into groups and each output module receives one group from every main crosspoint module. Input modules send a duplicate of one selected group to a redundant crosspoint module and output modules receive a group from a redundant crosspoint module and can use that group in place of any group from a main crosspoint module.
