Abstract
A USB-based on-line OSD (on-screen display) system includes at least a USB switching controller, a USB port switch, a display controller and at least one hardware actuator unit and a platform actuator unit. The USB port switch is connected to USB interface ports of at least two computers and is controlled by the USB switching controller to access and switch between the USB interface ports of the computers. The display controller is controlled by the USB switching controller to display the display image of the selected computer. The USB switching controller receives a switching command from the hardware actuator unit and/or the platform actuator unit and issues, in response thereto, a control signal to the display controller to switch the displayed image between the computers. The platform actuator unit that is embodied in the computers and is displayed on the display device provides a dialog box for operator selection between the computers.
