A method and apparatus for searching, browsing and summarizing moving image data using the fidelity of a tree-structured moving image hierarchy, which can partition or divide the moving image data into predetermined units, extract a key frame or representative frame from each of the partitioned or divided units, create a tree-structured key frame hierarchy on the basis of the extracted key frames, store a fidelity value of each of the key frames, which is a sub-tree information representative degree of each key frame, at an edge between adjacent ones of the key frames, and effectively and efficiently search, browse and summarize the moving image data using the stored fidelity values. Therefore, a query image or video clip desired by a user can more rapidly and accurately be searched for.

An apparatus and method for checking a link validity in a computer network, wherein, for the linking and referencing from one multimedia document to a different multimedia document in the computer network, desired information of the different multimedia document, such as last modified timestamp information indicative of a last modification time of the different multimedia document and latest version information of the different multimedia document, are stored in a validity check field, thereby assuring a link consistency. Therefore, the number of system errors can be cost-effectively reduced when referencing a multimedia document, and the reliability of searching and browsing can be increased.
