用于音视频文档内容描述的多媒体描述框架（MDF）
Multimedia Description Framework (MDF) for Content Description of Audio/Video Documents
摘要：
MPEG正在进行一项新的倡议，以标准化音频和视频数据/文档的内容描述。当MPEG-7在2001年定稿时，预计它将为复杂媒体类型的数据/文档的简明和明确的内容描述提供标准化的描述方案。同时，其他元数据或描述方案，如都柏林核心，XML等，在不同的应用领域变得流行。在本文中，我们提出了多媒体描述框架（MPEG-7），这是指定容纳多个描述（元数据）计划，MPEG-7和非MPEG-7，到集成架构。我们将通过实例来说明如何利用不同描述方案的组合优势来增强其表达能力和灵活性。最后，我们讨论了使用一个电影视频的XML描述搜索/检索所需的场景剪辑的电影，在XML原型系统，我们已经实现了文件。
英文摘要：
MPEG is undertaking a new initiative to standardize content description of audio and video data/documents. When it is finalized in 2001, MPEG-7 is expected to provide standardized description schemes for concise and unambiguous content description of data/documents of complex media types. Meanwhile, other meta-data or description schemes, such as Dublin Core, XML, etc., are becoming popular in different application domains. In this paper, we propose the Multimedia Description Framework (MDF), which is designated to accommodate multiple description (meta-data) schemes, both MPEG-7 and non-MPEG-7, into integrated architecture. We will use examples to show how MDF description makes use of combined strength of different description schemes to enhance its expression power and flexibility. We conclude the paper with discussion of using MDF description of a movie video to search/retrieve required scene clips from the movie, on the MDF prototype system we have implemented.
