After a long period of information construction, business efficiency and cost savings in companies have become increasingly demanding. A network conferencing system (NCS) is an effective way to solve these problems. The client in a network conferencing system is an important part of entire system. It has a direct impact on the efficiency of the overall system efficiency.After the requirement analysis of system functional, this thesis design and implement an efficient client of the network conferencing system. The design of the system architecture is by the analysis of the use cases and data flow diagram view of analysis. In this thesis, we design and implement a screen-sharing module and a network transmission module. By using the Block Collection and Picture Difference Capture and real-time transport (RTP) protocol, we maintain efficiency of the system. Finally, after the real-world environments running, the test results is this client of network conferencing system is feasibility and effectiveness. |
