  • Matrix architecture for KVM extenders
    Patent number: 7945703
    Abstract: A matrix architecture for KVM extenders connecting a plurality of console terminals and a plurality of computers. The matrix architecture for KVM extenders includes a plurality of first extenders and a plurality of second extenders. The first extenders transform keyboard, mouse analog signals into keyboard, mouse data packets and transform video data packets into video signals for console terminals. The second extenders transform video signals into video data packets and transform keyboard, mouse data packets into keyboard, mouse analog signals. The broadcasters broadcast keyboard, video, mouse data packets, each having a source address and a target address to couple computers to console terminals by broadcasting video data packets from second extenders to first extenders and to couple console terminals to computers by broadcasting keyboard, mouse data packets from first extenders to second extenders.
