Abstract
A method for generating on-screen display (OSD) image in a keyboard, video, mouse (KVM) system that includes a KVM switch, a plurality of computers and one or more console systems connected to the KVM switch. The console system includes a console side processor. The KVM switch generates drawing commands (including various data) descriptive of OSD images, and transmits the drawing commands to the console side. The various data may include vector graphic data, text data, and bitmap image data, but it does not include a bitmap representing the entire OSD image. The console side processor processes the received drawing commands and generates images representative of the OSD images based on the drawing commands, and displays the OSD images on the monitor of the console system.
