摘要

本文提出了一种基于通用多媒体场景中改编授权信息提取的新型上下文描述元数据。在对多媒体内容适配上下文的使用和表示进行深入研究后,我们得出结论,MPEG-21数字项目适配是该领域最适合的标准化倡议。然后,我们提出了一种灵活且可互操作的方式来表达基于配置文件和MPEG-21 DIA使用环境描述符的上下文信息。此外,我们的结果被应用于一个虚拟协作系统,该系统正在VISNET-II欧洲卓越网络(NoE)下开发。

A New Type of Contextual Information Based on the Adaptation Authorisation
This paper proposes a new type of context description metadata based on the information extracted from the authorisation of adaptation in a generic multimedia scenario. After a deep study of the state-of-the-art in the use and representation of contexts for multimedia content adaptation, we conclude that MPEG-21 digital item adaptation is the most suited standardisation initiative in this area. We, then, present a flexible and interoperable way to express contextual information based on profiles and on MPEG-21 DIA usage environment descriptors. Furthermore, our results are applied to a virtual collaboration system which is being developed under the VISNET-II European network of excellence (NoE).
