We describe XVIP, an XML-based video information processing system, which extracts information from video and stores the information in a multimedia digital video library. XVIP encapsulates a number of extraction techniques, including scene change detection, video optical character detection and recognition, and geometric coding. It also provides a seamless approach to scale up the contents created in and delivered by the target multimedia digital video library. Furthermore, XVIP can handle multilingual contents. XVIP is based on a multi-modal concept, which treats each content extraction component as a modality, and users can easily add new modalities into XVIP. The information extracted from the video is then stored in a flexible, scalable and reusable way based on a generic XML structure, providing a convenient mechanism for data representation on Web browsers. Also, the content in the XML file can be used to perform knowledge enrichment on top of the primary information extracted from the video. This enriched data representation helps users search for multimedia video content more efficiently.
