Interactive Digital Conference System Design And Implement

In recent years, as the network technology and communication technology continues to evolve and increasingly diverse needs of users on the network. Through the IP network transmission of multimedia information technology have continued to emerge, so the number of network-based Internet conferencing system as a new and advanced means of communication, for the convening of the meeting provides a feasible ways and means. Digital conference system is suitable for all areas of life, it is to improve efficiency and save costs and ensure the meeting to facilitate the timely distance has played an important role, now more and more units using this alternative to the traditional way of meeting face to face meeting.This paper presents a practical digital conference system design. The system is computer-controlled LAN-based interactive digital conference system, the use of C/ S/S software architecture and modular design, the system design for the client, server and data storage tertiary structure to ensure the system structure rational design; By the system modules, each module gives a detailed design, each module to serve different aspects of the meeting, so in accordance with the requirements of specific system modules can be combined with any load, the PC running the software connected with the system, making operation more convenient, efficient, and also makes data distribution easier. In the design of the integrated use of TCP/ IP protocol suite in the TCP, UDP and multicast communications technology, the combination of message-driven and polling the way the meetings between the client and meeting between the client and server-side communication, both to ensure the effectiveness of the system real-time communication, while greatly reducing the system's traffic.The system uses Visual C++ programming language development, using the MFC framework technology, ADO technology, socket and so on. Both to ensure efficient implementation of the system flexibility, but also intuitive and convenient user interface. Truly interactive digital conference system, digital, information and networking. Finally, the content of the study to adapt to current scientific and technological development and renewal,has some practical value.
