US 2010/0077061 A1 · REMOTE DESKTOP CONTROL SYSTEM USING USB INTERFACE AND METHOD THEREOF

Abstract

A desktop sharing and remote control system where the server (the controlled computer) and the client (the controlling computer) are connected by a USB cable. Either the server or the client includes a connecting section, which includes a control unit (MCU) and two USB controllers. The MCU transfers data between the two USB controllers. The server-side USB controller emulates a USB CD-ROM/keyboard/mouse composite device; the client-side USB controller emulates a USB CD-ROM. The server continuously writes video data (desktop image) to the server-side emulated CD-ROM and the client continuously reads the data from the client-side emulated CD-ROM and applies it to its monitor. Keyboard and mouse data is transferred in the opposite direction via the client-side emulated CD-ROM and server-side emulated keyboard and mouse devices. The connecting section stores applications programs to be automatically executed by the server and client using auto-run functions of the emulated CD-ROMs to accomplish plug-and-play.
