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.

Dependent claims

Video signal switching apparatus for supplying video signals from a plurality of video sources connected to the apparatus to a display device connected to the apparatus, the apparatus including:

a plurality of video signal deserialising devices each connectable to a one of the plurality of video sources and which convert digital video signals received from a one of the plurality of video sources into video signals having a lower data signalling rate;
a video signal serialising device connectable to the display device;
and
a data transmission means including a switch and which connects the plurality of data deserialising devices to the serialising device, the serialising device converting the video signals into serialised digital video signals having a higher data signalling rate, and in which the data transmission means selectively provides a video signal path between the serialising device and a one of the plurality of deserialising devices.
