Development of Advanced Image / Video Servers in A Video on Demand Testbed

This paper describes our current effort in building a video server with advanced capabilities of storage/indexing/ retrieval. The target application at this stage is Columbia University's Video on Demand (VOD) testbed. Our research focus covers innovative content-based visual query, multi-resolution (MR) video coding, efficient manipulation of compressed video, and optimal real-time video storage architectures. An important aim of our research is to enhance interoperability. Heterogeneous communication connections (ATM and Internet) have been installed. We discuss research progress and design strategies in various technical areas of this project.
