The paper introduces the remote control system based on TCP/IP and the software plug-in technology in today. To meet the demand of multi-protocol PTZ control, the system architecture is improved with adopting the design idea of software plug-in framework. The reformative remote control PTZ system is provided with well-designed extension and maintainability. Key words: remote control; PTZ control ; plug-in; digital video Service
