摘要： Managing metadata in a metadata transmission server by generating a plurality of metadata fragment data by partitioning metadata to be transmitted based upon predetermined segment units, selecting predetermined metadata fragment data from among the plurality of the metadata fragment data, generating metadata-related authentication information using the selected metadata fragment data, and transmitting the selected metadata fragment data and the metadata-related authentication information including data format information indicating type of the selected metadata fragment data. A metadata receiving client uses the transmitted metadata fragment data, the metadata-related authentication information and the metadata format type information to authenticate the received metadata.

摘要： A method of measuring a similarity between images is provided. The method includes the steps of (a) computing a statistical dissimilarity between the images; (b) computing a perceptual dissimilarity between the images; and (c) computing a dissimilarity between the texture features of the images based on the statistical dissimilarity and the perceptual dissimilarity. When images perceptually similar to a query image are searched and retrieved according to the above measuring method, the possibility that the retrieved images are not perceptually similar to the query image is small. Accordingly, the image searching performance can be improved when searching images having texture features similar to that of a query image.

摘要： Provided are a method of recording/reproducing data under control of a domain management system. The method includes extracting, from the write command, domain management information regarding the predetermined domain and contents, and copy control information specifying an extent of copying the contents within the predetermined domain; recording the extracted domain management information on the storage medium; generating a domain-bound flag that is used to determine whether the recording apparatus which records the contents on a storage medium is present in the predetermined domain, based on the extracted copy control information; and recording the domain-bound flag and the contents on the storage medium. Accordingly, it is possible to record contents, recording of which is limited within a predetermined domain, on a storage medium outside a slave under control of a domain management system, while preventing the contents from being reproduced within other domains.
