摘要： A plurality of audio object (AOB) files and a plurality of picture object (POB) files are stored. Default Playlist Information and sets of Playlist Information each show an order in which AOBs stored in the plurality of AOB files are to be reproduced. The DPLGI includes DPLI_POB_SRPs that specify at least one POB to be displayed during the playback period of AOBs indicated by the playback order given in the Default Playlist Information. The TKGI includes TKI_POB_SRPs that specify at least one POB to be displayed only during the playback period of a particular AOB out of the AOBs indicated by the playback order given in the Default Playlist Information.

摘要： When a recording media 10 including secure areas is inserted in an electronic terminal 30, the electronic terminal 30 reads a predetermined program from the recording media 10. As a result of processing performed by the program, the recording media 10 judges a boot state of the electronic terminal 30 when the recording media 10 is inserted in the electronic terminal 30. As a result of the judgment, when the recording media 10 is inserted in the electronic terminal 30 immediately after the electronic terminal 30 is booted, the recording media 10 imposes a loose restriction of accessing the secure areas. As a point of time when the recording media 10 is inserted in the electronic terminal 30 is nearer to a point of time when the boot of the electronic terminal 30 has been completed, the recording media 10 imposes a severer restriction of accessing the secure areas.

摘要： An encrypted-data decrypting apparatus that provides enhanced security protection for programs and data while they are in the processes of decryption to execution after having been encrypted. When a decrypted partial program needs to be loaded into the shared memory M, the controlling unit 11 loads it into an area indicated by the memory location information. According to the memory location information, a plurality of partial programs are sequentially loaded into an area so that one partial program gets overwritten by another; therefore, none of the partial programs exists in the memory for a long time, and thus there is less possibility of having the partial programs referred to illegitimately. In addition, since every time some data is decrypted, the decryption support program authenticating unit 13 confirms authenticity of the decryption support program P, it is possible to prevent having illegitimate references in which the decryption support program is abused.

摘要： A recording medium which allows consumers to access and purchase content while protecting the copyright of the content. The recording medium includes a secure data area and a non-secure data area. The secure data area is accessible by an apparatus whose authenticity is verified, and the non-secure area is accessible by the apparatus regardless of such verification. The secure data area stores a first content key. The non-secure data area stores first data and second data which can be decrypted. The first data includes a first encrypted content which is generated by encrypting a first content with the first content key, and the second data includes a second encrypted content which is generated by encrypting a second content with a second content key, where the first and second contents are related to each other.

摘要： A multiple function portable device prevents an occurrence of a situation in which a remainder of a battery is used up after a consumer utilizes a contents playing function of a portable device having a contents playing function, wherein not only the contents playing function but also basic functions inherent to the portable device become unavailable. A power supply control means commands a power supply means to stop the power supply to a contents playing function activator when the battery remainder measured by a battery remainder measuring means becomes lower than a predetermined value.

摘要： An object of the present invention is to provide a system in which it is possible to pre-warn the consumer who is trying to purchase contents that cannot be written on the PD that the contents cannot be written on the PD. Based on the PD writability information, the PD writability detector determines whether the contents distributed by the distribution system notified by the distribution system detector can be written on the PD. If it is determined that the contents cannot be written, the PD writability detector requests the controller to warn the consumer.
