  • Patent number: 8091005
    Abstract: In a keyboard-video-mouse (“KVM”) system in which a target computer may be wirelessly accessed by a plurality of remote stations, a method includes, by the target computer: obtaining a frame of video data; transmitting packets for the frame; transmitting a query packet; obtaining a list of requests from at least one of the remote stations, each request from a particular remote station identifying packets missed by that particular remote station; and resending at least some of the requested packets.

  • Patent number: 8079051
    Abstract: A system includes one or more transmitter devices constructed and adapted to transmit wireless streaming media, the transmitter device connected to at least one video source, wherein the transmitter device is further constructed and adapted to automatically detect a type of active source signal from the at least one video source and automatically to convert that signal, if necessary, to an appropriate output signal; and one or more receiver devices constructed and adapted to receive wireless signals, the receiver connected to at least one video output device, wherein the at least one receiver device is further constructed and adapted to produce, automatically, a appropriate signal for the at least one video output device connected thereto.

  • Patent number: 7627186
    Abstract: In a wireless keyboard-video-mouse (“KVM”) system in which a remote computer accesses the video output data of a target computer, a method of providing video data from the target computer to the remote computer, a method includes compressing at least some of the video data using a line fitting compression scheme to produce at least one sequence of absolute coded pixel segments and relative coded pixel segments which combine to represent the video data; and providing the sequence of absolute coded pixel segments and relative coded pixel segments to the remote computer.

  • Patent number: 7246183
    Abstract: In a wireless keyboard-video-mouse (“KVM”) system in which a remote computer accesses the video output data of a target computer, a method of providing video data from the target computer to the remote computer, includes obtaining an analog video signal from a target computer; disabling data compression of the video signal; determining a first phase (P) for analog-to-digital (A/D) conversion of the video signal; beginning compression of the video signal; and adjusting the first phase of the A/D conversion to produced a second phase (P?), based, at least in part, on a number of segments required to transmit the compressed video signal.
