    摘要: A recording apparatus is provided for an SD memory card that has a plurality of EPUBxxx.KEY files recorded thereon, each file having a plurality of Key&Rule Entry areas, and an SD_EPUB.MMG file being read from the recording medium prior to the writing of data. A bitmap in SD_EPUB.MMG shows for each EPUBxxx.KEY file whether the EPUBxxx.KEY file has at least one Key&Rule Entry area not in use, or whether all the Key&Rule Entry areas are in use. Based on the bitmap in the read SD_EPUB.MMG file, the recording apparatus opens EPUB#u.KEY having an unused Key&Rule Entry area and writes data into the unused Key&Rule Entry area in the file. If all the Key&Rule Entry areas in EPUB#u.KEY become in use as a result of the writing of the data, the recording apparatus updates the bitmap in SD_EPUB.MMG.

    摘要: A package management information recording section 131 creates a directory for each package for content distributed in package units, and creates a package management file indicating the relationship between a directory name and package identifier. A content file recording section 132 creates a content file group management file indicating the relationship between a content file name and a reference name when that content is linked from other content. A link resolution information recording section 133 creates a link resolution file indicating the correspondence between a reference name indicating content included in another package and the package identifier of the other package. A link resolution section 142 of a content playback apparatus 140 specifies a link destination content file using these items of file management information. By this means, a link between contents can be maintained even when distributed content is recorded with a name different from the original content file name.

    摘要: A package management information recording section 131 creates and records on a recording medium 120 package management information for managing packages recorded on the recording medium 120. A content file recording section 132 records on the recording medium 120 content files of content file groups included in packages, and also creates and records on the recording medium 120 content file group management information for managing these content file groups. A content/metadata correspondence information recording section 133 creates and records on the recording medium 120 information on correspondence between content files and metadata files within a package or correspondence between a package itself and metadata files. By this means, the correspondence between content files and metadata files can always be maintained correctly when they are recorded separately.

    摘要: There is provided a content use management method capable of preventing unauthorized distribution of a content and improving user-friendliness. In this method, the same group key is stored in a secure device (400) and a playback terminal (500). Moreover, a license issuing application is received from a license distribution server (200) and stored in the secure device (400). After this, a license encrypted by the group key is sent to the playback terminal (500) and the license encrypted by the group key is stored in the playback terminal (500). Upon playback of the encrypted content, the playback terminal (500) decrypts the license by using the group key and acquires the content decryption key, thereby decrypting the encrypted content. Even when the encrypted license flows into the network, it cannot be decrypted by a playback terminal not having the same group key and the copyright is protected. Moreover, the playback terminal (500) which already holds the group key and the license encrypted by the group key does not need the secure device when reproducing the encrypted content.

    摘要: A document retrieval system for searching a document coinciding with a retrieval request the user inputs and further ranking the document in accordance with the degree of coincidence between the document and the retrieval request. In the document retrieval system, a word frequency calculating section finds out the number of documents where a word appears, a frequency of occurrence of the word in a document and obtains a weighting parameter for the word, and a frequency score calculating section obtains a frequency score on the basis of the output of the word frequency calculating section. In addition, a word cooccurrence relation checking section checks word cooccurrence relations of the retrieval request and the document, and a cooccurrence score calculating section calculates a cooccurrence score from the degree of coincidence therebetween. A document score calculating section calculates a document score on the basis of the frequency score and the cooccurrence score. The documents are ranked in order of document score and displayed to the user.

    摘要: In a document retrieving apparatus, an audio input section converts a sound into a character pattern. A language model storing section stores likelihood information. A word choosing section obtains a word selection result based on the likelihood information. A retrieval condition producing section produces retrieval conditions based on the word selection result. A document storing section stores document to be retrieved. And, a document retrieving section retrieves the documents based on the retrieval conditions. An effective document search can be performed regardless of the sentence recognition accuracy without requiring higher cost in collecting the required language data.

    摘要: The invention is directed to a device that carries out secure distribution of a license particularly necessary for using a digital content in a copyrighted digital content distribution system. By a method of distributing a license according to the invention, a license encryption key for distribution is produced by a license distribution server based on a seed produced on the user terminal side according to a prescribed function F and the user terminal transmits a license based on the same seed and the same function F by a common-key method in a tamper resistant module. On the user terminal side, the stored seed is deleted once the license is decrypted.

    摘要: A searching apparatus includes an index generation portion for generating an index to provide data of the number of documents including the key word and the number of appearances of the key word. Matching degrees between the key word and documents are calculated from the number of documents including the key word and the number of appearances of the key word. A portion of documents are arranged in order of the matching degree in a buffer which are outputted as the searching result. Lower rank documents regarding the matching degree are searched by comparing the lowest matching degree of the neighbour higher ranked document arranged in the buffer. At first time searching, data of the latest edition of the documents stored in a memory is detected and stored and is used to provide second time searching operation to eliminate inconsistency in the searching result between the editions at first and second time searching operations. The index is generated every field of each document. The matching degree of combined field is calculated by logical operation between the two fields. Moreover, an index of combined field may be generated and one of field of the combined field may be omitted. The matching degree of the other field is also obtained by another logical operation.

    摘要: A system for providing keywords to facilitate a search in a text retrieval system. For each of texts constituting a text base, the system creates a word ID of each of words used in the text and a word occurrence count of a corresponding word. The word occurrence count indicates a number of occurrences of a word in each text. For each of words used in any of the texts constituting the text base, the system creates a total word occurrence count and a containing text count indicative of the number of texts containing the word. For each of words contained in the selected texts, a degree of importance is calculated by using the word occurrence count, the total word occurrence count and the containing text count. The words contained in the selected texts are sorted in order of the degree of importance. At least a part of the sorted words are displayed as related keywords.
