SYSTEM AND METHOD FOR DESCRIBING MULTIMEDIA CONTENT

摘要

There is disclosed a descriptor data structure representative of a selected feature of in a sequence of visual animated data frames, such as a video clip. The descriptor data structure comprises a standard descriptor template containing a block of pre-defined attribute fields associated with the selected feature and a block of user-defined attribute fields associated with the selected feature. The selected feature may be an object appearing in the visual animated data frames, a selected frame in the sequence of animated data frames, or a block of frames in the sequence of animated data frames. The structured defined nature of the descriptor template makes the descriptor data structure easily identifiable and easily searchable, thereby making the selected feature associated with the descriptor data structure easily identifiable and easily searchable.
