【摘要】 随着信息技术的飞速发展,因特网已成为信息知识传播的主要载体之一。多媒体信息在网上的传输越来越重要,流媒体技术由于采用实时性传输能够突破带宽限制的特点逐渐在许多领域得到了广泛应用。同时,网络流媒体资源也不可避免地面临着数字版权保护的问题,迫切需要流媒体数字版权管理系统来保障媒体内容版权拥有者的合法权益。针对目前流媒体版权保护存在的问题,在对现有数字版权保护技术的深入研究的基础上,论文从保障流媒体资源在网络上分发时内容完整性和传输安全性的角度出发对流媒体数字版权管理系统进行了总体的设计,并分别对系统需求、功能结构、信息结构、层次结构和整体架构进行了描述。然后论文结合数字版权保护相关技术对系统的关键模块进行了详细设计。最后论文对系统进行了测试和结果分析,表明该系统能够解决目前流媒体版权管理存在的问题。该数字版权管理系统不仅可以有效地保护内容提供者的利益,同时还保护内容使用者对内容的合法使用权。流媒体数字版权管理系统的设计实现解决了网络上流媒体资源打包加密和认证使用的问题。这将有利于流媒体资源数字版权的在线管理,杜绝流媒体资源在非授权情况下的肆意使用和传播,而且该系统的广泛应用和不断发展必将积极地推动基于网络的电子商务、远程教育等新型技术的发展。更多还原

【Abstract】 As the rapid development of information technology, the Internet has become one of the main carriers of information and knowledge dissemination. The transmission of multimedia information on the Internet has become increasingly important and the Real-Time Streaming Media technology has been widely used in many fields. Meanwhile, streaming media resources inevitably have to face the problem of copyright protection. It is so urgent that the need of Streaming Media Digital Rights Management System to protect the legitimate rights and interests of media content copyright owners.Focusing on the problem, thesis studies the present digital rights protecting technology and designs a Streaming Media DRM System, which is used to protect the copyright of digital network streaming media resources. The thesis gives the frame design from the perspective of the content integrity and security about the transmission of streaming media resources in the network, next to it, system requirements, functional structure, information structure, the overall structure and hierarchical structure are introduced..And then, thesis design the key modules of DRM system based on digital rights protecting technology. Finally, the fuction of the DRM system is tested. The result of the testing proves that this system can solve the present problem of copyright protection. The DRM System will not only be effective in protecting the interests of content providers, but also in protecting of the content users to use the content legitimately.The encapsulation and authentication of streaming media resources problem is solved by the design of the system. This will be conducive to digital copyright management of the online streaming media resources, so that they can avoid being disseminated indiscriminately. Next to it, the system can be widely used to promote the development of network-based electronic commerce and distance education systems.更多还原
