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.

To play back a content while managing the right of use of the content, such as a total time of playback of the content, an electronic device stores right information in a right temporary storage unit 59 and judges whether or not use of the content is permitted, in a process of decoding a frame. Also, the electronic device updates the right information stored in the right temporary storage unit 59. When the frame to be played back is the one at a predetermined position in order, the electronic device stores the right information stored in the right temporary storage unit 59 into a storage area 20.
摘要:
An audio stream is divided into a plurality of audio object (AOB) files that are recorded having each been encrypted using a different encryption key. At least one piece of track management information (TKI) is provided corresponding to each track. Playlist information (PLI) assigns a playback position in a playback order to each track when a plurality of tracks are to be played back one after the other.

A user terminal program enables a user terminal apparatus to accept instruction information specifying a content that a user wants to reproduce on a predetermined reproducing apparatus other than the user terminal apparatus, and enables acquiring system identifying information to identify a system to receive the specified content from a distributing site. Moreover, the terminal program enables judging whether the acquired system identifying information is included in a compatibility file which includes one or more system identifying information for receiving the specified content according to the system identifying information if the acquired system identifying information is judged to be included, and prohibiting receiving if judged not to be included. Furthermore, the terminal program enables writing the received content to an internal memory or an insertable memory of the predetermined reproducing apparatus.
摘要:
A program storage unit 111 stores a plurality of protected programs. The disabled-program list storage unit 117 stores information of disabled protected programs. An execution program selection unit 112 selects one of the protected programs that is not disabled, with reference a disabled-program list. If malicious analysis is detected before the protected program is executed or during the execution of the protected program, a malicious analysis detection unit 116 stops the execution of the protected program, and a disabled-program update unit 118 enters the disabled program into the disabled-program list.
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 content distribution system includes a reference server 112, and a plurality of distribution servers 101 to 108. The reference server 112 holds URLs showing network locations of the plurality of distribution servers 101 to 108, and transmits an URL for a distribution server to a user terminal in response to a user request. When one of the distribution servers 101 to 108 is accessed by a user terminal, the distribution server 101 to 108 determines whether access has been performed as a result of receiving location information from the reference server 112. If this is the case, the distribution server 101 to 108 generates payment information commanding the user terminal to pay the distribution server and the reference server 112, and transmits a distribution package including the payment information and a digital content to the user terminal.
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)
