20090202228 | INTEGRATED CIRCUIT OR USE IN PLAYBACK APPARATUS - 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. | 08-13-2009 |

20090238545 | REPRODUCING DEVICE AND PROGRAM - 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. | 09-24-2009 |
20090269028 | REPRODUCTION DEVICE AND PROGRAM - 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. | 10-29-2009 |
20090324202 | RECORDING MEDIUM, PLAYBACK APPARATUS, RECORDING APPARATUS, PLAYBACK METHOD, RECORDING METHOD, AND PROGRAM - A BD-ROM has recorded thereon: a plurality of subtitle streams each configured for playback in sync with a video stream; and PlayList information. The PlayList information includes PlayItem information and a display method flag. The PlayItem information defines a playback section with information indicating In_time and Out_time of a playback time axis of the video stream and includes a stream information table. The display method flag indicates whether or not control according to a subtitle display method is valid. The stream information table specifies to, a playback apparatus, one of the subtitle streams to be selected if the control according to the subtitle display method is valid. | 12-31-2009 |
20100046921 | REPRODUCER, PROGRAM, AND REPRODUCING METHOD - When a plurality of AVClips recorded on a BD-ROM and Local Storage | 02-25-2010 |
20100049992 | APPLICATION EXECUTING DEVICE, MANAGING METHOD, AND PROGRAM - A BD-ROM stores a disc root certificate | 02-25-2010 |
20100074594 | STEREOSCOPIC VIDEO PLAYBACK DEVICE AND STEREOSCOPIC VIDEO DISPLAY DEVICE - A video plane generation unit decodes stream data into a pair of left-view and right-view video planes, and outputs the pair alternately in a 3D display mode and either of the pair repeatedly in a pseudo 2D display mode. An image plane generation unit generates a pair of left-view and right-view image planes having an OSD at different horizontal locations according to its depth to be perceived, and alternately output the pair of image planes. A pseudo 2D display control unit instructs the video plane generation unit to operate in the 3D display mode and the pseudo 2D display mode in periods where the image plane generation unit does not and does output the image planes, respectively. The adder unit combines a video plane and an image plane generated by the video plane generation unit and the image plane generation unit, respectively, onto a frame, and outputs the frame. | 03-25-2010 |

20100194783 | MAP DISPLAY DEVICE - In a display device of the present invention, a map, one or more positions on the map, and one or more information pieces associated with the positions are stored; the stored map is displayed in on a display; one or more prescribed-sized display area portions of a display area, on which the map is displayed, is selected; and an information piece associated with a position on the map being displayed in the prescribed-sized display area portion is displayed on the map. | 08-05-2010 |
20110038616 | REPRODUCTION APPARATUS AND METHOD OF CONTROLLING A REPRODUCTION APPARATUS - Provided is a playback device which enables, when playing back a recording medium having recorded thereon a digital stream and an application program, an execution result of the application to be shared among a plurality of devices. By having a Java application data writing unit | 02-17-2011 |
20110044665 | RECORDING DEVICE, RECORDING METHOD, REPRODUCTION DEVICE, AND REPRODUCTION METHOD - Original data is copied from a read-only recording medium to a rewritable portable recording medium. A data storage unit stores therein updated data and mapping information indicating a path of the updated data in the virtual package. A determination unit determines, from the mapping information, a match between a path on the portable recording medium of first stream data included in the original data and a path in the virtual package of second stream data included in the updated data. When the match is determined, the recording control unit instructs that the first stream data be deleted from the portable recording medium. The recording control unit further instructs that the updated data be written on the portable recording medium. The data recording unit further writes and deletes data in response to the instructions from the recording control unit. | 02-24-2011 |
20120265985 | APPLICATION EXECUTING DEVICE, MANAGING METHOD, AND PROGRAM - A playback device reads an application and a digital stream from a recording medium to execute the application with playback of the digital stream. The playback device includes a management unit operable to verify authenticity of the application by judging whether a disc root certificate is identical to a first root certificate, and an execution unit operable to execute the application if authenticity of the application is verified by the management unit. The playback device also includes a storage unit having a storage area that is specified by a file path that uses the provider ID and a hash value of a second root certificate, and a playback unit operable to play back the digital stream in accordance with the playlist information. | 10-18-2012 |
