摘要：

This paper describes the modeling part of the project CODAC (Modeling and Querying COntent Description and Quality Adaptation Capabilities of Audio-Visual Data)(1). One of the CODAC project aims is the definition of a common framework for modeling content information and quality adaptation capabilities of audio-visual data. Descriptions which are indexed, i.e. stored in the meta-database, will be encoded as an MPEG-7 description. Such a model enables us to provide active components with valuable information to govern or enhance their media scaling, buffering, and caching policies on the delivery path to the client (network routers and proxy caches).
