The present invention provides a bitstream generation apparatus that enables an efficient editing of video objects in providing a finished audio video production. Audio and video data is encoded and an elementary encode unit correlates the audio and video data into video objects. The video objects can be assembled by an editing unit into a desired scenario of reproduction. An editor can re-arrange the scenes that are formed by the video objects with the assistance of a correction unit and an interleaving unit that can divide the pieces of audio data and the pieces of video data that form the video objects into new video objects which can be interleaved into the reproduction order of video objects without requiring a re-encoding of the entire set of video objects that constitute sequences of scenes for the audio video product.

On a BD-ROM, there is recorded is a digital stream into which video and audio streams are multiplexed. The video stream is composed of a plurality of pictures that together represent video. The graphics stream includes a PES packet storing state control information (ICS) and PES packets containing graphics data (ODSs). The graphics data constructs an interactive display. The state control information defines the control so as to change the states of buttons presented on the interactive display according to the reproduction proceeding and user operations.The ICS is attached with a PTS showing the display timing of a picture to be synchronized with the interactive display. The ODS is attached with a PTS showing the timing for decoding the graphics data. The timing shown in the ODS is prior to the display timing.

On a BD-ROM, an AVClip and a plurality of playback section information (PlayItems) are recorded. The AVClip includes a video stream multiplexed with a plurality of elementary streams. The playback section information Playable_PID_entries showing the playback start point and the playback end point in the video stream correlated with the filtering specification of each elementary stream. The filtering specification specifies whether each of the plurality of elementary streams are able to be played back or not.

Provided is a generating apparatus that generates a DVD-Video volume image, and a BD-ROM volume image, that each have: a digital stream, path information, and a jump table, where in the respective digital streams, a button command to be executed by a playback apparatus, in playing back the digital stream, is incorporated. A BD-scenario generating apparatus 7 obtains path information, a jump table, and a button command, which are for the BD-ROM, by converting any one of the description schemes for the path information, the jump table, and the button command for the DVD-Video.

An optical disk includes an audio data storage area for storing audio data; a still picture data storage area for storing a plurality of pieces of still picture data; and a management area for storing reproduction control information for controlling reproduction of the audio data and the plurality of pieces of still picture data. The reproduction control information has flag information representing specified still picture data among the plurality of pieces of still picture data.

The display unit displays an "Author" window and other windows that form a CUI according to control by the display control unit. The input operation unit receives inputs from the editor who views the "Author" and other windows. The window information storage unit stores the attributes of windows displayed by the display unit. The script information storage unit stores a template of scripts, including parameter strings, which conforms to the standards for multimedia optical discs and which is to be used for generating the outputted strings. The control unit interprets the operations received by the input operation unit 1501 and instructs the display control unit to display windows as required, in addition to storing variables that correspond to the parameters in the input data storage unit. The reproduction control information generation unit reads the data stored in the input data storage unit, uses the read data to set the parameters in the template stored in the script information storage unit, and outputs scripts for the system stream reproduction control information.

摘要:
To provide a sub-picture unit generation apparatus for generating a plurality of sub-picture units that compose a sub-picture stream which is interleaved with a video stream into a system stream, each sub-picture unit including a subtitle image that is to be superimposed on moving images reproduced from the video stream. The sub-picture unit generation apparatus includes an attribute storage unit for storing a display attribute that shows a base position for arranging each subtitle image, a character string storage unit for storing a plurality of subtitle character strings, a subtitle image generation unit for generating a subtitle image from one of the plurality of subtitle character strings stored in the character string storage unit, a display position determination unit for determining a display position of the subtitle image according to the display attribute, and a sub-picture unit generation unit for generating a sub-picture unit that includes the subtitle image and display position data showing the determined display position.
