Sichuan Radio And Exchanges And Cooperation Network System Design And Implementation

Internet makes information be processed, transmitted and released without the limit of time and space. Therefore, economic globalization and sharing of information have become indispensable in today's society. As one of the important media of information transmission, broadcasting stations in various levels are in face of a practical and urgent problem--how to show their own characteristics in the information age? How to provide with exact news in time? And how to improve the quality of programs to attract more audience? On the other hand, the development of network technology has greatly improved the efficiency of departments and staff, but how to take more advantages of the network technology to serve broadcasting stations? Sichuan broadcasting station communication and cooperation network system is designed to solve the problems above. I was in charge of developing the whole software system, which is implemented to manage reporters'and editors'work, to share excellent audio programs among broadcasting stations, and to manage the programs with scientific methods. The system can realize such functions as news edition, uploading and modification of manuscript, and news checking, evaluation and adoption as well. Based on the technology of VPN, the software can construct local network in internet with guarantee of transmission safety and achieve the reciprocal access among broadcasting stations in different levels. The system has been used by a few broadcasting stations in Sichuan Province. In this dissertation, I will illuminate the developing process of the software and the solutions to difficulties in the process as well. Multiple technologies and approaches are used in the system, such as: VPN, OOD, Database, and Audio Coding, which will be explained respectively in the dissertation. Furthermore, the testing situation, the significance and the shortages of the system will also be introduced in this dissertation.
