【摘要】 随着计算机网络、多媒体和通信技术的飞速发展，特别是结合计算机网络、多媒体压缩算法技术、宽带网络和计算机处理能力的显著进步，数字，网络，电视将融为一体，IPTV(Internet Protocol TV，网络电视)也得到了飞速发展，然而由此带来的媒体内容版权问题正直接影响和左右着数字媒体的价格和市场，抑制和阻碍了数字媒体内容价值的实现。如何保证IPTV的安全制作，分发，传播和收看，建立有效可行的访问控制和版权保护措施是内容提供商关注的焦点。本文在对基于IPTV的媒体内容版权保护技术进行分析和研究的基础上，设计并实现了一个基于数据库系统在线认证的IPTV版权管理系统。系统由后台数据库系统、前台发布和认证系统、客户接收系统三部分组成。本文主要研究工作包括以下方面的内容：1．对IPTV的现状及数字版权管理技术进行了分析和研究，包括IPTV的概念、系统体系结构和实现版权管理系统所涉及的关键技术等。2．详细论述了IPTV系统中DRM版权管理技术，并分析了该技术的实现机制和工作流程。提出了基于数据库系统在线认证的IPTV版权管理系统，包括系统体系结构、工作流程，并详细划分了系统的模块。3．开发并实现了基于数据库系统在线认证的IPTV版权管理系统中的后台数据库，许可证授权服务器和认证服务器三个子系统的工作流程和模块设计。4．完成了对后台数据库，许可证授权服务器和认证服务器三个子系统的功能测试。通过调试，证明了该系统的有效性，同时也证明了整个系统解决方案的可行性。更多还原

【Abstract】 With the rapid development of computer network multimedia and communication technology, IPTV (Internet protocol TV) get great progress simultaneity. However, the price and the market of digital media are influenced and controlled by the media content copyright question. Furthermore, the realization of the value of digital media content is suppressed and hindered in the same time. How to guarantee IPTV’s safe manufacture, distribution, transmutation and watching, and establish an effective and feasible copyright protective measure are the key points to digital media content-providers.An IPTV copyright management system based on on-line authenticated database was designed and realized in this dissertation after analyzed and researched media content copyright preservation technologies. The designed IPTV copyright management system was composed with three parts: the backstage database system, the onstage issuance and authentication system, and the customer receiving system. The main research contents were described as follows:1. The present situation of IPTV and digital copyright management technologies were analyzed, including the concept and the system structure of IPTV, the key technologies of DRM (Digital Right Management), and so on.2. An IPTV copyright management system was proposed after deeply researched the DRM in IPTV system, includes system structure, work flow and system module functions.3. Three subsystems of the proposed IPTV copyright management system were developed and realized, including the backstage database, the permit authorization server and authentication server.4. The function testing of the three subsystems were finished, through debugging, the validity of this system and the feasibility of this project were substantiated.更多还原
