【摘要】 NVD(Next-Generation Versatile Disc)是我国具有自主知识产权的红光高清光盘技术,拥有成本低、不受国外专利制约的优点,具有很大的市场需求。NVD产业的发展需要有高效的版权保护技术。目前应用于光盘的版权保护技术主要是为了防止光盘中的数字内容被非法复制和传播,但是其中大部分技术都被破解过。光盘厂商不断地提高光盘内容的加密强度和光盘播放机的复杂程度,但是事实证明这些行为收效甚微。数字版权管理是基于网络的数字版权保护技术,提供数字化和网络化信息服务,能够阻止未授权者对数字产品的非法使用,可以有效地保护数字产品知识产权。数字版权管理已经成为网络环境下保护数据内容的合法交易、传播和使用的一种重要手段。使用数字版权管理技术保护NVD版权是高清光盘版权保护的新方法。应用于NVD的数字版权保护系统参考了现有数字版权保护系统的功能结构、系统模型和技术原理,并且根据NVD硬件平台的实际性能,在完成功能要求的前提下,简化了系统结构,实现了一个简单模型。应用于NVD的数字版权保护系统涉及了NVD盘片,NVD视盘机,以及提供管理服务的服务器,采用了包含客户端、服务器、数据库的三层模型,综合使用了加密技术,数字签名技术,数字证书技术,版权描述语言等多种技术。服务器端是数字版权管理系统中实施管理行为的主要部分,主要完成文件加密、用户注册、许可证发放、认证等功能。更多还原

【Abstract】 NVD is the red high-definition optical disc technology belongs to China’s independent intellectual property rights. It is not subject to foreign patent constraints; it has many advantages such as low cost, and has great market demand. The development of NVD industries need to have effective copyright protection technology.The main target of current copyright protection technology used in optical disc are to prevent digital content from illegal copying and dissemination, but most of them have been cracked off. Optical disc manufacturers continue to improve the encryption strength of the content and the complexity of optical disc player.Digital rights management technology is net-based digital copyright protection technology, through a set of technologies, in the provision of digital and network information services, it effectively stop the illegal use of such information, it can effectively protect intellectual property rights of digital products. Digital rights management technology has become an important means to achieve the protection of the legitimate transaction data content, dissemination and use under the network environment.Using digital rights management technology to protect the copyright of NVD high-definition discs is a new method of the copyright protection technology for optical disc. the digital copyright protection system applied to NVD refer to the existing digital copyright protection system’s the functional structure, the system model and the principles of technology , According to the actual performance of the hardware platform based on NVD and under the premise of the completion of the functional requirements, simplifying the system architecture.the digital copyright protection system applied to NVD involving the NVD discs, NVD optic disc machine, and the provision of management services to the server, including the use of the three-tier model of clients, servers, databases, and integrated use encryption technology, digital signature technology and digital certificates technology, right expression language, and other technology. The server-side of digital rights management system implements the main part of system management, include file encryption, user management, licensing, and certification.更多还原
