中文简介:
如今,用户希望能够使用不同类型的设备访问他们的计算资源和所有类型的内容,从无线便携式设备到连接到局域网的固定设备,基于上下文的内容自适应已成为通用多媒体必不可少的访问(UMA)方案。这种内容改编代表了可能受知识产权(IP)法律约束的对象的修改,原始作者或权利持有人应该能够保留否决或限制操作的可能性。尽管MPEG-21解决了标准(DIA,数字项目适应)和第5部分中的权利表达语言(REL)的第7部分中的适应,但它仍然缺乏它们的集成方法。本文考虑了基于两个新的基于标准的本体的集成在一般多媒体场景中对上下文感知内容自适应的授权,这两个基于本体的语言在语义层面上提供了桥梁。首先,介绍了Context Aware Ontology(CAO),它模拟了MPEG-21 DIA标准中包含的通用环境描述符(UED)工具。然后,基于RRDOnto(代表权利数据)本体引入了适应授权人,该授权允许在支持MPEG-21许可模型的同时沿着价值链尊重知识产权。最后,描述了两者的集成,提供了一个联合模型,允许内容创建者和内容分发者控制适应。
课程简介: Nowadays, users want to be able to access their computing resources and all kind of content using different types of devices, from wireless portable devices to stationary devices connected to local area networks in a way that context-based content adaptation has become essential for Universal Multimedia Access (UMA) scenarios. This content adaptation represents the modification of an object possibly subjected to the Intellectual Property (IP) law, and the original author or rights holder should be able to retain the possibility of vetoing or restricting the operation. Whereas MPEG-21 addresses the adaptation in the part 7 of the standard (DIA, Digital Item Adaptation), and the Rights Expressions Language (REL) in the part 5, it still lacks of an integrated approach of them. This paper considers the authorisation of context-aware content adaptation in a generic multimedia scenario based on the integration of two new standard-based ontologies providing a bridge between them at a semantic level. First, it is presented the Context Aware Ontology (CAO), which models the Universal Environment Descriptor (UED) tool contained in the MPEG-21 DIA standard. Then, it is introduced the Adaptation Authoriser based on the RRDOnto (Represent Rights Data) ontology, which grants that IP rights will be respected along the Value Chain while supporting the MPEG-21 License model. Finally, the integration of both is described, providing a joint model that allows the adaptation to be controlled by Content Creators and Content Distributors.
