摘要:
When a plurality of AVClips recorded on a BD-ROM and Local Storage 18 constitute one stream sequence, a Playback Control Engine 32 starts playback if at least one AVClip of the stream sequence is in an enable status, even when the stream sequence also includes an AVClip which is in a disable status. While one AVClip is being played back, a Virtual FileSystem unit 38 changes a remaining AVClip to the enable status of being recognizable by the Playback Control Engine 32 or the disable status of being unrecognizable by the Playback Control Engine 32, according to a method call by an application.

A reproducing device includes: a user setting storage unit storing user setting preference information set by a user; a reproduction control storage unit storing reproduction-control-use preference information for controlling reproduction of a video content; a BD-J module executing an application together with reproduction of the video content recorded on a recording medium, such as a BD-ROM; a detection module (i) detecting whether the BD-ROM is mounted and, (ii) when the BD-ROM is mounted after once being removed, determining whether to continue, together with reproduction of the mounted BD-ROM, the execution of the application which was executed before the removal; and a password preference information setting module causing a reproduction control storage unit to store the user setting preference information as the reproduction-control-use preference information, when an application termination instruction is received from the user, or when continuation of the execution is determined.

A BD-ROM stores a disc root certificate 301 that is issued by a root certificate authority and assigned to the disc medium. An application manger 2 acquires a hash value from the disc root certificate 301 and verifies the authenticity of an application by using the hash value. If the authenticity is verified, the virtual machine 3 executes the application. A local storage 5 has a plurality of domain areas. Form among the plurality of domain areas, a security manger 4 allocates to the application a domain area that corresponds to the hash value.

Has an object of discarding an access permission to be discarded quickly and preventing illegal use of a device providing resources. A communication unit 101 communicates with a resource use device 30 and a resource providing device 20. An access permission unit 106 instructs the resource providing device 20 to permit an access from the resource use device 30. A storage unit 103 stores information on the resource use device permitted to access as management information. The existence check unit 107 checks a communication state with the resource use device 30, the management information of which is stored in the storage unit 103. The access discard unit 108 instructs the resource providing device 20 to reject an access from the resource use device 30, communication with which is determined to be disconnected by the existence check unit 107.
摘要:
An integrated circuit includes a storage that stores a module that has a function of a virtual machine for executing an application recorded on a recording medium. The integrated circuit also includes a central processing unit that executes the module to cause the virtual machine to function and a decoder, that is distinct from the central processing unit, that decodes a video stream and an audio stream that are included in digital streams stored on a recording media. When the central processing unit executes the module, a package manager manages status information of the digital streams. If at least one of the digital streams is in an enable status, the decoder decodes the digital stream. When the decoder decodes the digital stream, the package manager changes the status information of another digital stream to an enable status or a disable status according to a request from the application.

摘要:
A processing apparatus is connected to a network and has a content recording/playback function. The processing apparatus stores therein, in correspondence, (i) statuses of the recording/playback process and (ii) computer virus-handling processes to be performed if a detection unit detects a computer virus. If the computer virus is detected, the processing apparatus performs one of the computer virus-handling processes in correspondence with one of the statuses of the recording/playback processes.
摘要:
A playback apparatus plays back video data recorded on a recording medium such as a BD-ROM. The playback apparatus includes an interface in which a removable medium such as an SDRAM can be inserted, a detection module that detects that the removable medium is inserted, and a virtual file system. The virtual file system is used if the removable medium is detected to be inserted, if additional content such as subtitles is recorded on the removable medium, and furthermore if the additional content is associated with the video data recorded on the BD-ROM, etc. The virtual file system is used for dynamically combining the video data recorded on the BD-ROM, etc. and the additional content of the removable medium so as to play back a virtual package.
