Abstract: A simple resume reproduction device which performs resume reproduction after reproduction of content is interrupted. Content; an application that is a program for reproducing the content; and at least one reproduction control information item for controlling execution of the application are recorded on a recording medium. The simple resume reproduction device includes: a reproduction unit which reproduces the content by executing the application controlled according to a first reproduction control information item; and a reproduction information acquiring unit which acquires reproduction information indicating a reproduction position of the content. Further, the reproduction unit, when resuming reproduction, reproduces the content from the reproduction position indicated by the reproduction information without executing the application.

Abstract: In the case where plural applications are executed at the same time, if each application instructs for different trick play to the same content, a difference is caused between an ideal reproduction state expected by each application and an actual reproduction state. The present invention makes it possible to keep the reproduction state unchanged as long as normal reproduction or trick play is not accepted, by including a moving picture trick play reproduction management unit which determines, in response to an instruction for one of normal reproduction and trick play, whether or not to accept, according to a rule, the instruction, and retains details specified by the instruction in the case of accepting the instruction, and a moving picture reproduction processing unit which reproduces a moving picture based on the details retained by the moving picture trick play management unit.

Abstract: 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 604 operable to output, to the outside of the playback device, data stored in an ADA 602, which is an area capable of being accessed by a Java application identified by an identifier held by a BD-ROM, the playback device generates data which can be input to another device. By having a Java application reading unit 605 operable to read out information which can be used during an execution of the application from a data export medium 606 being a removable medium to store the read out data in the ADA 602, the playback device can inherit information of another playback device, and play back the recording medium continuously.

The terminal further includes a resource manager operable to provide, to a selected service, one or more resources indicated in the resource set information in the associated service execution environment, in the recording medium, stored by the storager.

Abstract: A method of manufacturing a disk substrate includes a disk substrate forming step of forming a disk substrate; and an outer chamfering step of chamfering an outer edge of the disk substrate. The outer chamfering step includes chamfering the outer edge by bringing an end surface of a cylindrical-shaped outer chamfering grindstone having a hollow portion on its end into contact with the outer edge such that the hollow portion faces the outer edge while rotating each of the outer chamfering grindstone and the disk substrate.

Abstract: When AV playback and an operation of BD-J application are executed in conjunction with each other, the playback apparatus saves values stored by the currently executed BD-J application into a nonvolatile memory upon termination of the BD-J application or the like. Next time the playback starts, the playback apparatus restores the values to an area accessible by the BD-J application, and subsequently, activates the BD-J application.

Abstract: The present invention is comprised of: the service execution unit 5701 that executes a service in the ServiceContext for Abstract service 2108; a method 6112 that associates the ServiceContext 2108 with resource set information indicating plural resources used by the service, when an application requests the service execution unit 5701 to execute the service; the ServiceContext management unit 2001 that holds the ServiceContext 2108 and the resource set information associated with each other by the method 6112; and the JMF 1705a that provides the service with the resource set information held by the ServiceContext management unit 2001.

Abstract: A plurality of video streams and STN_table are recorded in the local storage 200. Each of the plurality of video streams is a secondary video stream to be played together with a primary video stream, and includes picture data representing a child image to be displayed in Picture in Picture that is composed of a parent image and the child image. In the STN_table, entries of secondary video streams that are permitted to be played are described in the order of priority.

Abstract: The object of the invention is to provide a method of polishing the end surfaces of a substrate for a recording medium, which is capable of efficiently polishing the inner peripheral end surface and/or the outer peripheral end surface of the substrate preventing the reliability of performance of the recording medium from being impaired by the adhesion of the residual polishing material. According to the invention, there is provided a method of polishing end surfaces of a substrate for a recording medium wherein an inner peripheral end surface or an outer peripheral end surface of a substrate for a disk-like recording medium having a circular hole at the central portion thereof is brought into contact with a polishing medium obtained by dispersing polishing grains in a viscoelastic resin carrier and the polishing medium flows, thereby to polish the inner peripheral end surface or the outer peripheral end surface.

Abstract: There is provided a Java™ conditional access apparatus which, by describing a CA control unit through a Java™ program, obviates the need for porting a CA control program, enables development of a CA system over plural terminals in a short time, and obviates the need for terminal replacement. The Java™ conditional access apparatus includes a descramble circuit, a key generation information obtaining library, a Java™ VM, a storage unit, a condition-release control unit, an API having a registration unit. Upon receiving a function from a CA control program, the registration unit registers the received function. When the API receives information of a channel, the information of the channel to be reproduced is notified to the CA control program. The CA control program requests the key generation information obtaining library to obtain key generation information corresponding to the received channel information, and passes the received key generation information to the condition-release control unit.

Surfaces of an inside circumference and an outside circumference of the annular glass block are ground. The annular glass block of which the surfaces of the inside circumference and the outside circumference are ground are separated into individual annular glass substrates, and separated annular glass substrates are cleaned. Then, edge portions of the inside circumference and the outside circumference of a cleaned annular glass substrate are chamfered.
