Then, the receiving box sends the mouse information to the output card, one part of the mouse information is sent to the remote computer through the output card, and the other part of the mouse information is sent to the OSD display processing module.
Then, the output card respectively forwards the mouse information to the remote terminal and the OSD display processing module through the switching module according to different destinations of the mouse information.
Finally, the OSD display processing module carries out conversion according to the position of the mouse, if the mouse is positioned in the OSD area, the receiving box is forbidden to send the mouse information to the remote computer, and a command for drawing the OSD mouse is sent to the output card; if the mouse is in the non-OSD area, the receiving box is recovered to send the mouse information to the remote computer, and simultaneously, a command of hiding the OSD mouse is sent to the output card.
In one embodiment of the present invention, the detailed processing procedure of the keyboard event information is as follows:
firstly, the receiving box sends the keyboard information to the output card, and one copy of the keyboard information is sent to the remote computer and the other copy is sent to the OSD display processing module through the output card.
Then, the output card respectively forwards the keyboard information to the remote terminal and the OSD display processing module through the switching module according to different destinations of the keyboard information.
And finally, judging whether the mouse is in an OSD state or not by the OSD display processing module, and if the mouse is in the OSD state and the OSD menu is in a character input state, sending a character command for drawing the keyboard input to the output card. If the mouse is not in the OSD state, judging whether the key value is a certain shortcut key function, if so, calling the shortcut key function; if not, it is ignored.
By the implementation method, the OSD menu with any style can be drawn at any position on the display of the KVM seat, and the position and the size of the OSD menu can be dynamically adjusted at any time; by adding the processing of the mouse event, the function of the OSD menu can be quickly called through the mouse at any time, so that the operation and response of the OSD menu are more efficient; with the keyboard input function, some text editing work in the KVM system can be completed at the OSD interface, such as modifying the signal source name.
Based on the scheme of the invention, the interaction between other complex KVM seats, such as the chat room of a plurality of seats, the pushing and following between the seats can be realized by the OSD menu scheme to form a graphical operation interface.
