    摘要： A program execution device is a device for executing an application program having at least one class including an execution code created by an object directivity language. The program execution device includes a first execution device having a memory and a processor and a tamper-resistant second execution device having a memory and a processor. When a class is executed, a loader loads an execution code of the class in the memory of the second execution device and loads a portion of the class other than the execution code loaded in the memory of the second execution device, in the memory of the first execution device.

    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.

    摘要： The present invention is the playback apparatus 400 for (i) mounting thereon the BD-ROM 200 in which a plurality of data groups and an application program that refers to each of the data groups are stored and (ii) playing back each of the data groups by executing the application program. The playback apparatus 400 comprises: the playback processing unit 412 operable to control the execution of the application program; the network IF unit 419 operable to obtain, from an external server including therein one or more alternative data groups, an alternative data group to replace part of the data groups; and the HDD unit 418 that stores therein correspondence information showing a correspondence between a storage location where on an internal recording medium the alternative data group is stored and a storage location where on the external recording medium the part of the data groups to be replaced. Here, at a time when the application program in execution reads a data group being referred to, the playback processing unit 412 (i) judges based on the correspondence information whether an alternative data group for replacing the data group being referred to exists on the internal recording medium, and (ii) specifies, as a data retrieve destination, a storage location of the alternative data group indicated by the correspondence information when the judgment is affirmative.

    摘要： Hardware of a playback apparatus includes a drive and a decoder, and firmware of the playback apparatus accesses a BD-ROM loaded on a drive, according to a BD-J application, to bring the decoder into AV playback operations. The drive unit constitutes a local storage. A benchmark score is built in the firmware in advance. The benchmark score shows a turn-around time from when a processing request is made to the hardware via the firmware to when a response returns. Such a benchmark score is written into an application data area in the local storage when the firmware is initially executed.
