    摘要: A log region of a memory card includes a plurality of log entries and a plurality of administration information storage units. Each of the plurality of log entries includes a license ID region, a Ks2w region, a status region and a KPcmy region. The status region includes a ST1 region and a ST2 region to store the communication status. The license ID region stores a license ID. The Ks2w region stores a session key. The KPcmy region stores a class public encryption key of a memory card. The administration information storage unit stores the last record sequence number corresponding to the log entry storing history information of the latest communication.

    摘要: A decryption processing unit decrypts encrypted content data using a license key Kc. When an elapsed time after reception of the license key (Kc) does not exceed a hold time at a time of the license key (Kc) included in reproduction control information (ACp), reproduction of encrypted content data continues. When the elapsed time exceeds the hold time at a time, the license key (Kc) is discarded, and a reproduction control unit again obtains a license key (Kc) from a memory card. Discarding and reobtaining license key (Kc) continues until an allowable output count of license key (Kc) from the memory card becomes zero. As a result, a reproduction time of encrypted content data can be controlled safely.

    摘要: An information editing apparatus is provided which enables the user to clearly recognize the contents of recorded information which includes image information and is recorded on a recording medium. The information editing apparatus includes a first selecting device 14 for selecting a thumbnail image from images corresponding to the image information, the thumbnail image showing the contents of the recorded information recorded on a recording medium 1, a second selecting device 14 for selecting the thumbnail image from images other than the images corresponding to the image information in the recorded information, and a recording device 8 for recording first position information and second position information on the recording medium 1. The first position information indicates on the recording medium 1 the recording position of image information corresponding to the image selected by the first selecting device 14. The second position information indicates on the recording medium 1 the recording position of image information corresponding to the image selected by the second selecting device 14.
