Abstract: There is provided video switching circuitry for use in a KVM switch and similar devices. Video signal switching circuitry can supply video signals from a one of a plurality of video sources connected to the circuit to a display device connected to the circuit. The high data signalling rate signals are converted into a greater number of lower data signalling rate signals for switching by a bus architecture. Also provided are video display systems in which analogue and digital video signals are switched synchronously to allow them to be displayed on common or separate display devices. Also described is a high-resolution monitor digital video data switching device.

Abstract: A video switch for allowing at least two users to view video data from respective ones of at least two video sources. The video switch comprises a switch for selecting one of the at least two video sources and at least one sampler connected to the switch. The sampler is for sampling video data from the at least two video sources. The video switch further comprises a controller for controlling the switch and sampler to select one of the at least two video sources and sample a frame of video data. An output is provided for transmitting video data to one of the at least two users. The output supports a maximum number of simultaneous users which is at least two, and the number of samplers in the video switch is less than the maximum number of simultaneous users. A video switch according to the present invention allows a sampler for capturing video data to be shared between at least two simultaneous users. This reduces the cost, size and complexity of the hardware required to implement a video switch.
