ABSTRACT
Multimedia Database Management Systems (MM-
DBMS) have to efficiently provide the specific functionali-
ties required by time-dependent multimedia data types. Dur-
ing presentation playout, this requires support for
continuous data delivery and media-oriented optimization
of presentation quality according to users' requirements. In
this work, we describe our way to integrate this type of sup-
port transparently with other MM-DBMS functions like me-
dia editing and querying. This has been achieved by extend-
ing an existing data model, in particular by means of stream
abstractions for editing and presentation, and by extending
