Abstract
The present invention relates to a system and method for switching keyboard and mouse devices and video displays, as well as USB peripheral devices, between USB hosts and video sources over extended distances. Provided is a distributed KVM and peripheral switch where a USB keyboard and mouse is emulated to the host interfaces of the KVM and peripheral switch and a USB host is emulated to keyboard and mouse interfaces of the KVM and peripheral switch. In addition, the keyboard, mouse, display and peripheral devices are separated from the hosts and video sources by a non-USB communications channel.

34. A method for switching keyboard and mouse data, USB peripheral data and video signals over an extended distance, the method comprising:
-
receiving at a device unit USB keyboard and mouse data from a keyboard and mouse and USB peripheral data from a USB peripheral;
converting the received USB keyboard and mouse data to non-USB keyboard and mouse data suitable for transmission over a non-USB communications channel;
converting the received USB peripheral data to non-USB peripheral data suitable for transmission over a non-USB communications channel;
receiving at a host unit video data from a video source;
determining a destination USB host for the keyboard and mouse data, a destination USB host for the peripheral data, and a destination video display for the video data;
transmitting the non-USB keyboard and mouse data and non-USB peripheral data to a host unit via a non-USB communications channel;
transmitting to a device unit the video data;
converting the non-USB keyboard and mouse data received at the host unit to USB keyboard and mouse data;
converting the non-USB peripheral data received at the host unit to USB peripheral data;
transmitting the USB keyboard and mouse data and USB peripheral data to a USB host via a USB communications channel; and
