Based On The Java Video Conferencing System Design And Implementation

As the developing of Multi-media technique and the network technical, the method of meeting just change from the traditional meeting mode to modernization of meeting mode, the people takes part in meeting hoped to use more abundant way to expression,such as use of a video frequency, voice, the picture etc. Information carried on to live a new life dynamic exchanges, with development of the global integral , requested the people that attend meeting can participated in a meeting ,at a arbitrarily time, arbitrarily the location, this produced a video frequency meeting.combined the forerunner's network technique, computer technique and multimedia correspondence technique, as long as owned one set computer and connected into a network, then can participate in a meeting in the world-wide locations, biggest place then people carry on the exchanges of information.The thesis introduced the basic principle of multi-media correspondence, the relationship multimedia with video frequency meeting and introduced the development history and type of video frequency meeting, domestic and international of research circumstance, and introduced the related technique of video frequency meeting.The thesis passes analytical existing software and hardware of video frequency meeting, compare with the C|S structure and B|S structure of the merit and shortcoming of the video frequency meeting, choose JMF within Java as the basic development terrace, adopt C|S structure, put forward of a kind of viable video frequency meeting solution. Now through the use of multimedia software Java development mainly JMF packages, based on the analysis of the structure and the working principle JMF ,then using it to realize the video conference system of multimedia processing. This paper expounds the need of the video conference system development, through the design of the whole system, determine the realization system of the system design,then detailed introduction the design of each function module , determine the functions and database that this system should have ,and made the main module system coding.The thesis detailed explanation the key technical problems of the network video conference system, audio, video capture and receive.and use timestamp to resolve the problem of audio and video synchronization. .at the same time, the paper design the system should have sub-system,such as conference management and electronics whiteboard.
