    摘要: A BD-ROM playback apparatus for selecting and playing back one among text subtitle streams together with a moving picture. PSR 48-61 store Decode Capability flags whose set values indicate, for each language, whether or not a decode capability is present. Procedure executing unit 20 judges whether each text subtitle stream can be displayed, by referring to the set values of the flags. Stream selection unit 17 selects a text subtitle stream judged as being able to be decoded.

    摘要: After sizes of Intra pictures included in a digital stream are detected, an analysis unit 6 totals numbers of occurrences of the Intra pictures for each size to obtain an occurrence distribution of the sizes of the Intra pictures. Values “000b” to “111b” are respectively assigned to distribution ranges of the sizes of the Intra pictures. Then, an entry map, in which each Intra picture is represented by one of the values “001b” to “111b”, are to be recorded onto a recording medium in association with the assignment information.

    摘要: A BD-ROM playback apparatus simultaneously executes reproduction of a title including an AVClip and executes an application. The BD-ROM playback apparatus includes a BD-J module (35) executing an application, a playback control engine (32) for playing the AVClip belonging to one title, and a module manager (34) for controlling branching between a plurality of titles. The title includes a data management table. The data management table indicates an application read priority level for each title. The BD-J module (35) includes a java virtual machine (38), a local memory (29), and an application manager (36) for loading the application to the local memory (29). The application manager (36) reads in the application into the local memory (29) according to the read priority level of each application and the memory size of the local memory (29).

    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.

    摘要: Video streams and an entry map are recorded on a BD-ROM in association with each other. The video stream constituting a slide show includes a plurality of IDR pictures. The entry map (EP_map) associated with the IDR pictures indicates an entry time (PTS_EP_start) of each IDR picture included in the video stream in association with an entry point (SPN_EP_start). Application_type indicates that entry information of each of pieces of picture data constituting the video stream exists in the EP_map and each piece of picture data is to be decoded independently. Playlist information includes a plurality of pieces of playback path information, each including time information designating a piece of picture data and period information indicating a period for which playback of the pieces of picture data is paused.
