项目摘要

The tree year research can be summarized as following five points.1.We propose a method to transfer and/or combine various rights information by the reliable info-transmission guaranteeing the correctness of the log as recorded at terminal.2.We propose a method of flexible rights information distribution of rights holders, and also propose and evaluate a method of re-composition and re-editing rights information in a distributed processing way.3.We propose a scalable method for rights information processing that enables to describe content-viewing rights and corresponding control without any contradictions. By the method, allowed.action(s) against any segment of content and viewing rights relationship among contents can be described. Moreover, "targeting" satisfying users' preferences and new functionality called "content substitution" are enabled. We also evaluate the prototype system.4.We clarify functions of rights information processing entities and relationship among them. Three entities (license control function, right inheritance control function, and license/right management log function) are essential and enable not only the primary content distribution but also the secondary.5.We name the future multimedia environment "Content Circulation" where content consumers may act as content creators, circulatedly or repeatedly, and also clarify the issues of secondary content distribution and related rights processing. At generating derived rights information, the proposed language automatically processes and generates it while respecting the original rights and guaranteeing the consistency of rights of the originals and the newly generated ones.The open issue still remaining is to build up a prototype system in order to validate and evaluate the proposed method of 5.

树年的研究可以总结如下五点。1。我们提出了一种通过可靠的信息传输转移和/或组合各种权利信息的方法描述内容观看权和相应的控制，而无需任何矛盾。通过该方法，可以描述允许的内容。此外，启用了满足用户的偏好和新功能称为“内容替代”的“定位”。我们还评估了原型系统。4。我们澄清权利信息处理实体的功能及其之间的关系。三个实体（许可控制功能，正确的继承控制功能以及许可/正确的管理日志功能）至关重要，不仅启用了主要内容分布，还可以启用次要分布。5。我们将未来的多媒体环境“内容循环”命名，其中内容消费者可以作为内容创建者循环或反复充当内容，并阐明二级内容分布和相关权利处理问题。在生成派生的权利信息时，提议的语言会自动处理并生成它，同时尊重原始权利并保证原件和新生成的权利的一致性。仍然存在的开放问题是建立一个原型系统，以便验证和评估5的5种方法。
