Description
Technical Field
The invention belongs to the technical field of seat cooperation, and particularly relates to a KVM seat system signal source preview system and a KVM seat system signal source preview method.
Background
Previewing and switching of signal sources for multiple computers and/or servers and/or other devices may be accomplished by a KVM switch. The KVM switch is mainly used to securely access computers, servers and other devices from local users or remote users through a console composed of a keyboard, a mouse and a display, and to control the local or remote users through a network.
The switching method of the KVM switch is generally: three types of button switching, OSD menu switching and shortcut key switching. The button switching uses a physical button on the KVM, and the corresponding server can be selected by directly pressing the physical button. The OSD menu is software inside the KVM system, and can be switched by selecting a corresponding server with a mouse according to the name of the server displayed on the menu. The shortcut key is generally a combination key, such as Ctrl and a data key, 1, 2, 3, 4 servers, and pressing Ctrl +1 to select the first server is simple and convenient. In some technologies, a keyboard-screen-mouse switching method [1] is adopted to implement preview and switching of a signal source, but a preview picture in an OSD interface of a KVM needs to be read from a special picture capturing device at regular time, a picture is displayed at a very low refresh rate, a keyboard needs to be used for matching operation when switching the signal source, and the operation is complex and low in efficiency. In other technologies, a visualization method [2] is adopted to realize the preview and the switching of the signal source, but the preview image is displayed on a touch screen monitor and can only be used for signal switching.
Generally speaking, in the prior art, when a signal source needs to be switched, a signal source preview image can be seen only through a text interface or a separate switching interface, the function is single, the operation is inflexible, the efficiency is low, and a real-time preview picture of a computer list cannot be called out on a display by using an OSD menu only through a set of keyboard and mouse, and then the selection and the switching are carried out.
