The research is supported by National Science Foundation career grant, IIS-9733730. Our research group will investigate integration of multimedia technology with database systems for supporting sophiscated multimedia presentations. Such presentations can be constructed from various database resources and contain various aspects of multimedia characteristics. Because of the complexity and flexibility of such applications, the existing work in multimedia research cannot be directly applied to such environment. To support such applications, both multimedia and database technology must be integrated together to provide capabilities of retrieval, transmission, and presentation of multimedia data.

The research group will focus on formulating the principles for ensuring consistant multimedia presentations and designing robust techniques to retrieve and transmit multimedia database to users. Specifically, we will:

• develop a framework for ensuring consistent presentation of multimedia data based on quality-of-service(Qos) requirements;
• develop adaptive end-to-end control approaches to supporting transmission of multimediadata over networks;
• formulate a resourse allocation model for the database to allocate resources for data retrieval;
• implement and experiment with a distributed multimedia database protype for supporting educational digital library.
