Embodiment 1
[0070] Embodiments of recording media related to the present invention are described below. First, one usage form among the implementation forms of the playback apparatus related to the present invention will be described. Fig. 1 shows a typical usage form of the playback device related to the present invention. In FIG. 1 , a playback device related to the present invention is a playback device 200 . The playback device 200 is used to provide movie works in a home theater system composed of, for example, the playback device 200 , a remote controller 300 , and a television 400 .
[0071] Typical forms of use of the playback apparatus of the present invention are as described above. Next, a recording medium for playback by the playback apparatus pertaining to the present invention will be described. In the given example, the recording medium played back by the playback apparatus pertaining to the present invention is a BD-ROM 100 (optical recording medium). FIG. 2 shows the ...
Embodiment 2
[0237] This embodiment relates to improvement when performing title calling. Title invocation causes the called title to play after first pausing the current title, then resume the original title after playback of the called title has ended. Since title calling is predicated on continuing playback, the playback control engine 32 saves the system parameters for playback control stored in the PSR into the backup PSR when the title is called, and after the playback of the called title ends, Restore saved parameters to PSR.
[0238] Below is a list of system parameters stored in the PSR. PSR 0 to PSR 12 store system parameters showing playback status, PSR 13 to PSR 19 store system parameters set as preferred by the player, and PSR 20 to PSR 32 are backup PSRs.
[0239] PSR0: I graphics stream number
[0240] PSR1: audio stream number
[0241] PSR2: P graphics stream / TextST stream number
[0242] PSR3: angle number
[0243] PSR4: current title number
[0244] PSR5: current c...
Embodiment 3
[0280] The present embodiment relates to a method for managing versions of merge management information and specifying additional content for merge from a resident application in a playback device. Fig. 35 shows typical contents of a merge management information file related to this embodiment. In Embodiment 1, the merge management information file (or more precisely the merge management information stored therein) is updated by rewriting the old merge management information, thereby causing the old information to be erased. In this embodiment, new merge management information is continuously added to the file, and old information is not rewritten even for the same disc ID. Thus, if the virtual file system unit 38 cancels the generation of the virtual package and reverts to the original BD-ROM, information reflecting this state is retained in the merge management information file. In this case, the corresponding unit in the merge target directory of the merge management infor...
