Design And Implementation Of Videoconference System Based On SIP

Along with the constant development of the Internet, the exchange of information between people is increasingly frequent, mutual collaboration between the project is also increasingly important. The Video Conference System Application also become wider, and how to achieve the efficient, low-cost, stability, good scalability of the video conferencing system has been the pursuit of enterprises objective.The current video conferencing systems for the main signaling protocol are H.323 and SIP. Although based on the H.323 video conferencing systems research and development is relatively mature, but because of its high cost of hardware, not suitable for small and medium enterprises and personal to use. SIP, with its simple, flexible, open, scalability characteristics are very good fit for the Video Conference System Construction. Research and Implementation of the system have a profound significance and practical value.SIP-based video conferencing system has multiple models. In a detailed analysis of the demand for video conferencing systems, this paper presents a model similar to the component architecture and the design of choice on mixed mode as video conferencing system implementation model. SIP client is achieving the audio and video communications, the management and control of basic functions, and also has instant messaging, collaborative work functions such as scalability, and gives intelligent system upgrade solutions. After a rigorous system testing, the design is expected to achieve the target. Practice shows that the research results and the design ideas expounded by the method is reasonable and feasible, it's high reference value for the development of the follow-up system.
