Abstract

A Keyboard, Video and Mouse (KVM) switch is a hardware that allows multiple computers to connect to a single monitor, keyboard and mouse. KVM switches are used commonly in places that demand for multiple computers. It allows users to toggle between the computers at the press of a button. Though it is possible to work with multiple computers, many of the operations between the KVM connected computers are feasible only if those computers are networked. Copying of images and text is an example of one such operation. This paper describes a method to carry out operations such as copying images/text between the computers that are connected to the same KVM switch but without a network connection.

Copying text between different systems without a network connection when they are connected to a KVM switch

Usage of multiple computers at the same location is very common even at house hold level. However, the usage of individual video display monitor, keyboard and mouse for each computer occupies huge space. Besides the space, in a business environment, the productivity of the user is also lessened, when the user has to switch between the computers. With the availability of KVM switches, the space problem is considerably solved by means of using a single keyboard, video and mouse for all the computers that are connected to a KVM switch. The user gains productivity by toggling between the computers but using the same keyboard, video monitor and mouse. Usually each KVM can support 2 to 8 computers. However, by daisy chaining the KVMs one can scale the number of computers that can be controlled by a single Keyboard, Mouse and Monitor. By far, the recent KVMs support almost all well known operating systems running on different hardware architectures, including the laptops.

Many operating systems provide utilities that allow users to select text/image(s) on the display, cut/copy and paste between different sessions/windows that are displayed on the display terminal window from the same computer. However, such cut/copy/paste operations are not supported between windows/sessions displayed from different computers, even if those computers are running the same operating systems and are connected to the same display terminal through a KVM switch. This report describes a method that lets the users to execute cut/copy/paste operations between computers that are connected to the same display terminal through the same KVM switch but not connected to the network.

The invention described here involves a technology that can be embedded in the KVM switch. This technology is capable of storing text/image object(s) that are displayed on the monitor which is connected to the KVM switch. Similarly, the described technology also is capable of r...
