Research And Development Of Network Video Monitor Technology And System Based On Streaming Media

With the development of network and multimedia technology,the application of the network video monitor system is more and more extensive.However,the network video monitor system often cannot adapted well to the high real-time requirement,and low-level efficiency of the video streaming transmission cannot satisfied the system requirement.All of the shortcoming limited the development of the network video monitor system all the time.The development of streaming media technology gives a chance to better solve this problem.We can send the sustained encapsulated video data stream to receiver according to the gradation of time by use of streaming media technology,and the receiver can play video streams received from network.It can improve systematic real-time character through adopting this method.In this paper,the streaming media technology applied to network video monitor system are researched on the basis of video streaming.The emphases are put on system design,video captures and play,and the design of network transmission module and relevant software development method.In fact,uality of service of the network has unstable characteristics,we have analyzed QoS guarantee strategy in video streaming transmission on network,and presents a integrated QoS guarantee scheme which based on data encapsulation,buffer storage technology and congestion control on network.This scheme do its best to avoid the big delay or congestion on network based on make full use of network bandwidth,which can guarantee the best QoS of the video transmission.The software of this system use C/S communication pattern over IP.With the tool of C++ language,this software is compiled with Visual C++ under Windows2000 platform.C++ language has the advantage of using fewer system resources,high performance efficiency and flexible operate for low level system.During the development of this software,the objected-oriented analysis design method is adopted from the analyzing,designing,coding and testing,which guarantees the quantity of the software.
