We present an interactive content-based video browser allowing fast, non linear and hierarchical navigation of video over the Internet through multiple levels of key-frames that provide a visual summary of video content. Our method is based on an XML framework, dynamically generated parameterized XSL style sheets, and SMIL. The architecture is designed to incorporate additional recognized features (e.g. from audio) in future versions. The last part of this paper describes a user study which indicates that this browsing interface is more comfortable to use and approximately three times faster for locating remembered still images within videos compared to the simple VCR controls built into RealPlayer 2 Internet Video Browsing Browsing, retrieving, and manipulating digital video are increasingly important tasks within multiple domains including professional, entertainment, consumer applications, and in digital libraries. Interactive video browsers that make use of automatic video analysis allow for such capabilities. A current paradigm is to structure a video into a video table of contents (VTOC) composed of scenes, shots and key-frames. Several tools have been developed under this framework [1, 2, 3].
