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 data recording medium by which, when encoding an externally input AV signal to an MPEG transport stream, the MPEG_TS can be quickly and efficiently converted to an MPEG program stream conforming to a DVD standard, is provided. An apparatus and method for recording to the data recording medium are also provided. A flag indicating that a first stream (such as an MPEG transport stream) is recorded in a constraint format enabling efficient conversion to a second stream (such as an MPEG program stream) is written to the management information (VOBI). By referencing this flag the recorder can easily determine if the recorded data was recorded in the specified constraint format without analyzing the data recorded to the data recording medium.

摘要： A parallax information detection unit detects parallax information based on a motion vector obtained resulting from motion compensation on a 3D video performed by a decoder, and converts the detected parallax information into a stereoscopic effect level. Then, a control unit compares the stereoscopic effect level with a lock level recorded in a lock level register, and performs stereoscopic display effect control based on a result of the comparison.

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.

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： A BD-ROM 100 and a local storage 200 contain dynamic scenarios (programs) such as a Java application and a Movie Object. A dynamic scenario reads profile information from PSR 31 of the playback apparatus and judges whether or not the playback apparatus is an audio-only type. If it is judged that the playback apparatus is not the audio-only type, an interactive screen is displayed to perform a control to play back a digital stream according to an operation made onto the interactive screen. If it is judged that the playback apparatus is the audio-only type, a control is performed to play back a digital stream according to an operation that is made without use of the interactive screen.
