碩士 === 淡江大學 === 資訊工程學系 === 85 === In the new age of computer industry, multimedia network system is the major gravity of computer communications. Especially, network brings us convenience, and network applications continuously change and improve day by day. Therefore, data communication can not be disregarded. The most of network utilization is in data transmission. Data delivery has transmission norm (i.e., transmission protocol) and interface. The most popular wide area network is the Internet, which uses TCP/IP and WINSOCK for networking application program to realize transmission protocol and interface. For a network programmer, if one wants to design a network program, he/she must face to some difficult technique problems of program implementation, such as the complicated and fragmentary of interface control, besides face to network transmission control. Even the use of network is very extensive, the development of network application programs, especially for education are very few. The reason is that, not many researches propose the integration of multimedia network transmission system. In this thesis, the design of an integration of multimedia network transmission system is proposed. The system provides the designer some application interface functions to design network interface. The mechanism is not only for convenience, but also degrease the learning curve and require no understanding of the operation of TCP/IP or WINSOCK. There are four parts in the system structure: Connection Manager Module provides functions of connection; Send Module provides functions for transmission; Receive Module provides functions about accepting transmission data; and Send/ Receive Conference Module provides functions for conference. The system allows a programmer to use some convenience network transmission functions, without a deep study of WINSOCK interface. Thus, the programmer can focus on other issues of program development.
