摘要： On a BD-ROM, PlayList information is recorded. The PlayList information includes MainPath information and SubPath information. The MainPath information and SubPath information include connection_condition information and sp_connection_condition information, respectively. The connection_condition information and sp_connection_condition information indicate that, when the connection state between two MainClips referred to with the MainPath information is seamless connection (CC=5), the connection state between two SubClips referred to with the SubPath information is also seamless connection (SP_CC=5). In the case of CC=5 and sp_CC=5, IN_time of PlayItem is equal to IN_time(SubPlayItem_IN_time) of SubPlayItem.

摘要： An information recording medium capable of converting a stream including seamless connection, which is recorded in a constrained format allowing format conversion, from a first format (MPEG-TS) to a second format (MPEG-PS), into a second stream, and an apparatus and method for recording information in the information recording medium. The constrained format is provided for enabling conversion from a first format (for example, MPEG transport stream) to a second format (for example, MPEG program stream). According to the constrained format, when the connection information of the playback portion indicates a seamless playback, the system stream immediately before a seamless connection point ends with a complete data management unit (Capsule).

摘要： On a BD-ROM, PlayList information is recorded. The PlayList information includes MainPath information and SubPath information. The MainPath information specifies one of a plurality of AVClips as a MainClip, and defines a primary playback section on the MainClip. The SubPath information specifies, among the rest of the AVClips, one AVClip as a SubClip, and defines, on the SubClip, a secondary playback section to be synchronized with the primary playback section. The PlayList information includes an STN_table, which indicates SubClip and, from among a plurality of elementary streams multiplexed into the SubClip, elementary streams allowed to be played back. A total data size of AVClip per unit time is, for example, less than or equal to 48 Mbits when the AVClip includes a plurality of elementary streams allowed in the STN_table to be played back and does not include elementary streams which are not allowed in the STN_table to be played back.

摘要： A playback device for playing back a graphics stream in accordance with a stream selection table recorded on the recording medium. A procedure means determines a playback type of a graphics corresponding to the current stream number, based on the playback capability indicated by the capability register.The playback of graphics streams falls into two types, one of which is a first playback type in which a monoscopic graphics stream is used and the other is a second playback type in which a pair of left-eye graphics stream and right-eye graphics stream is used to perform a stereoscopic playback. The capability register indicates whether or not a capability to perform the stereoscopic playback by using the pair of left-eye graphics stream and right-eye graphics stream is present in the graphics decoder.

摘要： A main-view stream and a sub-view stream are recorded on a recording medium. The main-view stream is used for monoscopic video playback. The sub-view stream is used for stereoscopic video playback in combination with the main-view stream are recorded. The main-view stream includes a plurality of main-view pictures, and the sub-view stream includes a plurality of sub-view pictures. The main-view pictures and the sub-view pictures are in one-to-one correspondence. A B picture is not used as a reference picture for compression of any of the sub-view pictures whose corresponding main-view picture is one of an I picture and a P picture.

摘要： A BD-ROM has a video stream and an entry map recorded thereon. The entry map indicates a plurality of entry points (SPN_EP_start) in the video stream, in one-to-one correspondence with a plurality of entry times (PTS_EP_start) and flags (is_angle_change_point). Each flag (is_angle_change_point) indicates whether a picture located at a corresponding entry point is an IDR picture for causing decoder refresh or Non-IDR I picture having a reference to a preceding picture.

摘要： A stream generation apparatus of the present invention is a stream generation apparatus which generates a stream including coded pictures and a command for managing a buffer which holds a decoded picture, the command being added to one of the coded pictures as a reference picture. It includes a judging unit which judges whether or not the coded picture to which the command is added is skipped at the time of trick-play, an adding unit which adds, in the case where the coded picture is judged to be skipped, repetition information indicating the same contents as the command to another coded picture that follows, in decoding order, the coded picture judged to be skipped and that is not skipped at the time of the trick-play, and a generating unit which generates the stream including the coded pictures, the command and the repetition information.
