    摘要: According to one embodiment, since key information is written after a drive unit and host unit are assembled into a player, it is not necessary to manage, in the assembled player, the correspondence in secret key information between the drive unit and host unit. Further, in the player, even if, for example, the drive unit must be exchanged for another, encrypted key data can be shared simply by writing another key data item.

    摘要: On receiving a fast-forward playback instruction from a remote-control manager, a system controller determines whether the fast-forward playback speed is equal to or higher than a predetermined speed and whether the display screen should be divided into sections. If it determines that the display screen should be divided, the system controller determines how many sections the screen should be divided into, in accordance with the fast-forward playback speed. The system controller informs a GUI manager that the display screen should be divided into sections, the number of which has been determined.

    摘要: There is disclosed a digital information system which has a digital contents protection function using WM information. The system uses the WM information during a first ripping processing to execute a first verification processing for verifying validity regarding use of contents. In this case, ID information of music contents as a ripping object is registered. The system uses the ID information to execute a second verification processing for verifying the validity regarding the use of the contents without executing the first verification processing using the WM information during the ripping processing of the music contents corresponding to the registered ID information.
