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.

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.

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 (PlayItem) 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 (SubPlayItem) to be synchronized with the primary playback section. The SubPath information includes In_Time information and Out_Time information which indicate In_Time and Out_Time, respectively, of the SubPlayItem. In_Time and Out_Time of the SubPlayItem match In_Time and Out_Time of the PlayItem.

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.

A BD-ROM has a video stream, playlist information, and an entry map recorded thereon. The playlist information defines a playback path by indicating a sequence of one or more pairs of a playback start time (In_time) and a playback end time (Out_time) within the video stream. The entry map (EP_map) indicates positions (SPN_EP_start) and playback times (PTS_EP_start) of a plurality of intra pictures in the video stream, in one-to-on correspondence with flags (is_angle_change_point). Each flag indicates whether a corresponding intra picture is an intra picture (IDR picture) for causing decoder refresh or an intrapicture (Non-IDR picture) having reference to a preceding picture.

A BD-ROM on which an AVClip and a Java™ application are recorded. The AVClip includes a video stream and an audio stream multiplexed therein. On the BD-ROM recorded further are management information and the Mixing_On flag corresponding to the management information. The management information indicates a playback control of the AVClip that is to be played back when the Java™ application is executed. The Mixing_On flag indicates whether or not when a user performs an operation on the Java™ application being executed while the AVClip is under the playback control, mixing of the click sound with an audio output of the AVClip is available.

A BD-ROM has recorded therein an AV Clip generated by multiplexing a video stream and a graphics stream. The graphics stream represents an interactive display to be overlayed with the video stream, and includes a sequence of three Button State groups. The interactive display includes a plurality of buttons, each of which changes from a normal state to a selected state, and from the selected state to an active state, according to a user operation. In the three Button State groups in the graphics stream, the first-order group (N-ODSs) is made of a plurality of pieces of graphics data, which represent normal states of the buttons, the second-order group (S-ODSs) is made of a plurality of pieces of graphics data, which represent selected states of the buttons, and the third-order group (A-ODSs) is made of a plurality of pieces of graphics data, which represent active states of the buttons.

A BD-ROM has recorded therein an AV Clip generated by multiplexing a video stream and an interactive graphics stream. The video stream representing a motion picture made of a plurality of pictures, and the interactive graphics stream representing an interactive display to be overlayed on the motion picture, where the interactive graphics stream includes state control information (ICS) stored in a packet and a graphics data sequence (ODS), and the packet includes a time stamp that indicates a time at which the initial display is performed, the time being obtained by adding a predetermined duration to a decode ending time (PTS) of graphics data positioned midway through the graphics data sequence (S-ODSsfirst, S-ODSslast).

摘要:
A data processor according to the present invention includes: a receiving section to receive a data stream including data of first primary video to be presented by switching pictures at a first vertical scanning frequency and data of first auxiliary video to be presented synchronously with the first primary video; and a converting section for converting the first primary video data and the first auxiliary video data into data of synthetic video to be presented by switching the pictures at a second vertical scanning frequency, which is different from the first vertical scanning frequency. The data stream includes timing information defining respective times to present the first primary video and the first auxiliary video. The converting section associates second auxiliary video, having the same contents as the first auxiliary video on a picture of the first primary video, with a picture of second primary video, having the same contents as the counterpart of the first primary video, thereby generating synthetic video composed of the second primary video and the second auxiliary video.
