Abstract: An apparatus and method for extending high definition multimedia signals from a source to a display over long distances (e.g., up to 300 feet) using a single cable medium having a plurality of twisted pair conductors contained therein. The extender transparently supports HDMI and/or DVI signaling, which allows encrypted video content to be displayed at the remote display (or other sink device). Display data channel control (DDC) information is sampled and transferred in packet from the local unit to a remote unit to comply with high-bandwidth digital content protection (HDCP).

Abstract: HDMI extenders based on HDBaseT technology are disclosed for extending HD signals from a video source to a display over a twisted pair cable. The extenders include local and remote units. The local unit receives HD signals from the video source; converts them into differential multimedia signals based on HDBaseT technology communicated over the cable to the remote unit which recovers the HD signals for the display. The local and remote units can also facilitate exchange of USB information, and/or digital or analog audio as differential common mode signals, and/or power as common mode signals along with the differential multimedia signals through the twisted pair cable. The remote unit can also receive IR commands, generate modulated signals preserving the IR carrier frequency of the commands; and transmit the modulated signals over the cable to the local unit for recovery of the IR commands to communicate to the video source.

Abstract: A Keyboard, Video, Mouse (KVM) switch that includes one or more input ports to receive events, notifications and/or alarms generated by an external device. The KVM switch receives the events, notification and/or alarms in the form of an external signal. The KVM switch processes the external signals and compares the received external signal to one or more reference signals to identify an event that corresponds to the received external signal. The KVM switch then generates an announcement for display on one or more displays associated at least one user station coupled to the KVM switch.

Abstract: The present invention relates to a system and method for switching keyboard human interface devices (HIDs) and video displays. Provided is a switch with emulation support for advanced HID features. The switch uses information contained in HID report descriptors to extract information contained in HID reports and insert the extracted information into a switch report, which is sent to a host computer.

Abstract: The present invention relates generally to a system and method for providing a user access to a Keyboard, Video, Mouse (KVM) drawer based upon biometric authentication of the user, and more particularly, to a system and method for providing a user access to at least one host computer associated with a KVM drawer based, at least in part, on the user's unique biometric data. In one embodiment, an emulation controller, which emulates a KVM switch, is enabled or disabled based upon whether the associated user is properly authenticated. In another embodiment, an input-output buffer is enabled or disabled based upon whether the associated user is properly authenticated. Methods are also provided wherein the storage device containing at least a portion of the biometric data associated with authorized users is enabled upon receiving biometric data associated with a user of the KVM drawer.
