Abstract: Disclosed is a method of updating a graphical rendering, in a system display by a system controller, of technology assets operationally connected to the system controller.

Abstract: A computing and communication module, includes: a processing circuit; and a keyboard, video and mouse, KVM, extender transmitter disposed in signal communication with the processing circuit; wherein four equally sized ones of the module are collectively sized to fit within a volume of space defined by 1 racking unit, 1RU.

Abstract: A communication system includes: a transmitter configured to be responsive to a control request from a local device that facilitates toggling of the transmitter On and Off in a pattern of interruption to generate multiple consecutive On/Off bits having On/Off signals with a same pulse width that represents control information, the transmitter configured to transmit data via a communication medium at a first end thereof, the communication medium also having a second end; and, in response to the pattern of interruption, the transmitter is configured to interrupt the communication medium at the first end, each interrupting of the communication medium at the first end resulting in a detection of a loss of signal at the second end.

Abstract: A method, apparatus and system for changing to which remote device a local device is in communication via a communication medium, communicates with a matrix switch forming part of the system by interruption of the communication medium by the local device. Upon receipt of a unit of information via interruption of the communication medium, the matrix switch causes the local device to be in communication with another remote device other than the remote device that it was previously in communication. In one embodiment, the switching is to a next available remote device of a plurality of remote devices while in another embodiment, the matrix switch switches the local device to a switch configuration device for further communication therewith via the communication medium, thereby allowing the local device to select which other remote device it desires to be in communication.

Abstract: A video data extension system includes a transmitter and a receiver for transmitting and receiving encoded serial data. Transmitter is configured to receive one SDI 3G video stream at 2.97 Gb/s, two HD-SDI video streams at 1.485 Gb/s, two SD-SDI at 270 Mb/s, or one HD-SDI at 1.485 Gb/s and one SD-SDI at 270 Mb/s. Received data is segmented into packets to form an extended video stream for transmission at 3.75 Gb/s. To each packet, idle and header are provided. Data such as RS422 data may be included in the extended video stream. Where the received data includes data from two HD streams, received data are segmented into two groups of data packets for arranging into extended video stream in an alternate manner. Upon receiving the extended video stream, receiver uses idles to align data and header information to separate the HD streams.

Abstract: A multirate transmission system for transmitting parallel input data from a first location to a second location includes a transmitter portion and a receiver portion. The transmitter portion receives the parallel data, including the information related to a parallel data clock and stores the data in a buffer where it is subsequently read and serialized for transmission on a serial data link to the receiver portion where it is deserialized, including recovery of the parallel data clock in the serialized data stream. The receiver portion stores the parallel data in a buffer where it is read at a data rate corresponding to the parallel data clock of the incoming parallel data. The parallel data at the transmitter portion is associated with generated control characters when parallel data is not read from the buffer associated with the transmitter portion.

Abstract: A matrix router and method of switching comprising a combined input stage and output stage (I/O stage) having m matrix switch(es), each matrix switch having n inputs and n outputs, each input of said n inputs switchable within said matrix switch to any output of said n outputs, k core outputs and k core inputs, each input of said n inputs switchable to any core output of said k core outputs and each core input of said k core inputs switchable to any output of said n outputs; and a core stage having a matrix switch at least with m times k core stage inputs and at least m times k core stage outputs, each core stage input connected to one core output of said I/O stage, and each core stage output connected to one core input of said I/O stage, where m, n and k are integers and m?1, n?2, k?n.
