A digital video archive system differs from a regular digital archive system in that it can manage multimedia resources, such as video and audio contents, as well as metadata textual documentation. Thus, a complete digital video archive system must combine various technologies of multimedia searching and presentation. This paper takes the Development of Value-Added Application on Video Archive, a sub-project of the National Science Council’s digital archive application project, as a case study to demonstrate the role of information science technologies in developing digital video archive systems and digitizing video and audio resources. By sharing our experiences and the technologies developed in our research, we expect to provide digital content providers and researchers with guidelines for the design and development of digital video archive systems and value-added video/audio data. We also highlight some difficulties and suggest possible solutions to assist in the future development of digital video archive systems.

Its main purpose is to offer free public access to a digital library of 6,000 volumes (3000+ hours) of 16mm and Beta cam video footage. This video content was produced or collected by Dr. Daw-Ming Lee, an associate professor of Taipei National University of the Arts (TNUA). The Development of Value-Added Application Video Archive extends this digital library of excellent video footage and integrates it with a commercial process by adding membership management, online trading and editing of video/audio resources, and data integration across web sites. Users can browse the video/audio database and purchase segments of the content, which is our goal of adding innovative value to a regular video/audio digital database. The Development of Value-Added Application on Video Archive is funded by the National Science Council (NSC) Digital Museum project. This is a collaborative project between the TNUA, the Institute of Information Science (IIS) of Academic
