西南科技大学 毕业设计（论文） 题目名称：基于DVB-C 的文件广播系统发送端软件设计 年 级：2003级 ■本科 □专科 学生学号学生姓名：李 波 指导教师：周金治 学生单位：信息工程学院 技术职称：讲师 学生专业：电子信息工程 教师单位：信息工程学院 西 南 科 技 大 学 教 务 处 制 基于DVB-C 的文件广播系统发送端软件设计 摘要：为解决互联网迅速发展的“宽带瓶颈”与“信息垃圾”等问题实现资源的有效利用，DVB-C的来发送文件的思想。论文分析统一内容定位技术，出该系统在VC++ 6.0平台上的实现方案。由UCL标准框架确定文件信息标引元素运用Access生成文件信息标引数据库采用ADO技术文件信息标引数据在MFC环境下调用由蓝拓扑公司生产的MPEG传输流发送卡的接口函数编写和调试程序实现了服务器端客户端存储。实验结果表明，基于DVB-C的方案是可行的。 关键词ADO技术 The Software Designation of Sending Based on the Documentary Broadcasting System of DVB-C Abstract: In order to resolve the problems which are brought by rapidly development of Internet, such as bandwidth bottleneck, information garbage and so on, implement the use of resource effectively, the author proposes a sort of documentary broadcasting system based on DVB-C to send files. This thesis studies the implemental theory of documents broadcasting system, and analyzes the technology of uniform content locator, and then presents the scheme for this system on the platform of the VC++6.0. The author sets the documentary information indexing by the UCL standard frame and uses the Access to build information indexing database, adopts technology of ADO to visit and manage information indexing database, then under the environment of MFC calls the API function of MPEG-2 transport stream send card designed by BLUETOP Corporation to code and debug the program, completes the designation of software of the sending end. Finally this thesis completes the designation of implements cycle sending of server. And debug with the client successfully, complete the choose receive and restore in the client. It is workable for the scheme based on the Documentary Broadcasting System of DVB-C, which is proved in the experiment.
