    摘要: A BD-ROM stores PlayList information. The PlayList information defines a playback section of each of a plurality of AV clips and includes MainPath information and SubPath information. The MainPath information designates one of the AV clips as a Main Clip and defines a portion of the Main Clip as a primary playback section. The SubPath information designates another one of the AV clips as a SubClip and defines a portion of the SubClip as a secondary playback section that is to be played back in synchronism with the primary playback section. The BD-ROM stores, the one of the AV clips designated as the SubClip along with an EP_map. The EP_map shows a plurality of entry points on the SubClip in a one-to-one correspondence with entry times on the SubClip timeline.

    摘要: A BD-ROM contains PlayList information. The PlayList information defines a reproduction section for each of a plurality of AV Clips and contains MainPath information and SubPath information. The MainPath information specifies one of the AV Clips as the MainClip and defines a main reproduction section for the MainClip. The SubPath information specifies another one of the AV Clips as the SubClip and defines a sub-reproduction section to be synchronized with the main reproduction section for the SubClip. The BD-ROM contains those AV Clips specifies as SubClips while being correlated with EP_map. The EP_map correlates and indicates the entry time in the time axis of the SubClip with a plurality of entry positions in the SubClip.

    摘要: In a playback device for playing back a moving image recorded on a recording medium while executing an application recorded on the recording medium, to improve the use efficiency of a memory bus when combining the moving image with an image relating to the application. Whether or not to combine a background image, which is used as a background of GUI graphics such as a menu or a moving picture used by the application, is determined depending on whether the moving image covers the entire background image. If the moving image covers the background image, there is no need to combine the background image with the moving image. In this case, a memory bus allocated to the reading of the background image can be used for, for example, writing the moving image read from the recording medium onto a memory. Hence the memory bus bandwidth can be effectively used.
