Abstract:
1. 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; wherein the plurality of video signal deserialising devices, the video signal serializing device, and the data transmission means of the video switching apparatus reside in a common switching unit.
