Abstract

Traditional browsing of large multimedia documents (e.g., video,audio) is primarily sequential. In the absence of an index structurebrowsing and searching for relevant information in a long video, audioor other multimedia document becomes difficult. Manual annotation canbe used to mark various segments of such documents. Different segmentscan be combined to create new annotated segments, thus creatinghierarchical annotation structures. Given the lack of structure inmedia data, it is natural for different users to have different viewson the same media data. Therefore, different users can createdifferent annotation structures. Users may also share some or all ofeach other‘s annotation structures. The annotation structure can bebrowsed or used to playback as a composed video consisting ofdifferent segments. Finally, the annotation structures can bemanipulated dynamically by different users to alter views on adocument. BRAHMA is a multimedia environment for browsing andretrieval of multimedia documents based on such hierarchicalannotation structures.
