摘要： A data recording system 1 includes: a file generating part 3 for dividing digital data so as to generate a plurality of data files and recording the plurality of the data files sequentially into a recording medium 5; a management file judging part 6 for determining one management file for recording management information of the plurality of the data files; and a management information generating part 4 for recording the management information of the plurality of the data files into the determined management file. The management file judging part 6 determines the management file such that the number of the data files managed by the management file does not exceed a maximum data file number L (L is a natural number) that can be managed by the management file. Thereby, it is possible to record the plurality of the data files that are divided from the digital stream data and are recorded, such that the management of the plurality of the data files is easy.

摘要： An input-mode determination unit determines an input mode to be a graphic mode in the case where the number of sets of coordinates included in a coordinate sequence stored in the coordinate-sequence storage unit is smaller than a predetermined number and points represented by the coordinates are within a predetermined distance range, and otherwise, determines the input mode to be a curve mode. A line-to-draw sequence generation unit generates a line-to-draw sequence according to the input mode which the input-mode determination unit has determined to be.

摘要： A recording/reproduction device 10 receives content broadcast from a content provision device 11. The recording/reproduction device 10 encrypts the received content using a device key, to generate first encrypted content. The recording/reproduction device 10 decrypts the first encrypted content to obtain the content, performs an image conversion on the obtained content to generate converted content, and encrypts the converted content using a medium key to generate second encrypted content. The recording/reproduction device 10 writes the second encrypted content, the medium key, and the device key to a portable medium 14. When the portable medium 14 is inserted in a mobile information terminal 15, the mobile information terminal 15 decrypts the second encrypted content using the medium key to obtain the converted content, and reproduces the converted content.

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： An apparatus and method for storing and retrieving data files from a storage medium are disclosed. A storage medium stores one or more data files and address information showing the path of each data file. The address information is characterized in that numerical values derived or converted from given parts of the path names are used as the address information, whereby a data configuration which occupies less memory space than storing the path names as character strings. A numerical value can be designated from the numerical values and a character string can be generated from the numerical value to retrieve a corresponding data file.
