摘要:
The invention relates to power saving in portable terminals (100) with recording media (200). Conventionally, there is the problem that a battery (104) in the portable terminal (100) may become exhausted and as a result the original function of the terminal cannot be performed. To solve this problem, when the remaining battery capacity is low, the invention controls power supply (108) to the recording media (200) and clock supply (110) to a CPU (202) in the recording media (200) so as to reduce power supplied to the recording media (200)

A distribution server 103 distributes a content via a network, and a KIOSK terminal 105 receives the content via the network and records the content in an SD memory card 100. A customer device 111 receives a content via the SD memory card 100, checks out the content and records a copy on a recording medium. SD-Audio players 122 to 124 receive a copy of the content and play back the copy. Here, the KIOSK terminal 105 records a Usage Rule that certifies the right to control recording of content on the SD memory card 100. Move Control Information showing the number of times that moving of rights is permitted is set in the Usage Rule.

摘要:
A semiconductor memory card which allows consumers to access and purchase content while protecting the copyright of the content. The memory card has a unique media ID assigned thereto and includes a secure data area and a non-secure data area. The secure are 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 area stores a first encrypted content which is generated by encrypting a first content key by using the media ID, and the non-secure data area stores trial data and purchase data which can be decrypted. The trial data includes a first content which is encrypted by using the first content key, and the purchase data includes a second content which is encrypted by using a second content key. The purchase data can be decrypted when fee processing is performed.

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:
A semiconductor memory card stores a plurality of audio objects (AOBs) that compose a plurality of tracks and playlist information showing a reproduction order for the tracks. The semiconductor memory card also stores, as resume information (PLMG_RSM_PL), (1) a Playlist_Number showing which playlist information was used the last time playback was performed for the semiconductor memory card, (2) a Track_Number showing the last track to be played back, and (3) a Playback_Time showing a position at which where playback was stopped as a time expressed in relation to the start of the track.
摘要:
A transportable recording medium includes an area for storing encrypted cookie information. The same cookie information is thus easy to use in different terminals and the cookie information becomes unique to respective users instead of respective terminals. A Web site reads the encrypted cookie information, decrypts the encrypted cookie information using a secret key stored in the Web site, customizes a requested service according to the decrypted cookie information, and provides the customized service to a terminal. If the Web site stores non-encrypted user information, the recording medium stores a media identification. The Web site stores the user information so that the user information of the user assigned to the recording medium is searched for according to the media identification. The Web site reads the media identification from the recording medium, searches for user information corresponding to the media identification, and customizes a requested service according to the user information.
