| With the continuous development of the information society,multimedia technology and network communication technology is constantly to change,video conferencing is constantly deepened.Video conferencing is a new form of meeting after entering the information society.Beginning with the traditional conference difference is that his data transfer functions and images more powerful,under the traditional way of meeting its agreement in general is H.323 protocol,this agreement has been behind the development requirements of the times.From the current status of development,the technical conditions of videoconferencing has some had things,but now,when conducting video conference on the private network and dedicated hardware dependencies is quite large,but these restrictions have video conferencing adversely impact development.In this paper.Firstly,this paper introduces the of the status quo of the research significance and the domestic and foreign development and the basic concept of video conference and and related protocols are described in detail,and shows the video meeting the relevant standards and framework structure.Analyzed the H.323 protocol and H.264 protocol and H.320 technology comparison,so as to carry on the network,the terminal function and the data management function and so on to analyze the video conference’s demand.Introduces the basic system configuration of system function,conference and meeting safety and meeting management function,and modern video conferencing system detailed design(login module design,management interface design,envelope system design,detailed introduces.This paper also attempts to system modeling and system class diagram,sequence diagram,activity diagram and state diagram of the show,from the theoretical point of view the video conference system is can be fully realized,and meet the public demand.Finally,the development of video conference system and the deep extension of the prospect. |
