Multimedia Description Framework (MDF) for Content Description of Audio/Video Documents

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 language and 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, RDF, etc., are becoming popular in different application domains. In this paper, we propose Multimedia Description Framework (MDF), which is designated to accommodate multiple description (meta-data) schemes, 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 MPEG-7 Content Set to search/retrieve required audio and video documents from the set utilizing an MDF prototype system we have implemented.
