- An AVClip composed of a single elementary stream is called a SubClip.
- a SubClip is a file that stores only interactive graphics streams, only audio streams, and only text data.
- the interactive graphics stream, which is a SubClip is loaded into memory in advance during playback, and is played back in synchronization with other AVClips.
- preloading when playing back the AVClip, loading the SubClip into the memory in advance is called preloading.
- FIG. 4A is a diagram showing a configuration of the interactive graphics stream.
- the first level shows a sequence of TS packets constituting the AVClip.
- the second row shows the PES packet sequence that makes up the graphics stream.

- END END of Display Set Segment
- ICS is called a screen composition segment
- PDS, ODS, and END are called definition segments.
- the correspondence between PES packets and functional segments is one-to-one and one-to-many. In other words, the functional segment is converted into one PES packet and recorded on the BD-ROM or fragmented, converted into multiple PES packets and recorded on the BD-ROM.
- Interactive Composition Segment is a functional segment that controls the screen composition of interactive graphics objects.
- the ICS of this embodiment implements a multi-page menu.
- ODS Object_Definition_Segment
- a graphics object in run-length code format consists of a plurality of run-length data.
- the run-length data is data representing a pixel sequence by a pixel code indicating a pixel value and a continuous length of the pixel value.
- Pixel Code is an 8-bit value, and takes a value of 0-255. In the run-length data, any 256 colors can be selected from the full-color 16,777,216 colors by the Pixel Code and set as pixel colors.

- the PES packet is composed of a packet header and a payload, and this payload corresponds to a functional segment entity.
- DTS and PTS corresponding to this functional segment exist in the packet header.
- a functional segment is stored. DTS and PTS existing in the header of the PES packet are treated as DTS and PTS of the functional segment.
- FIG. 5 is a diagram showing a logical structure composed of various types of functional segments.
- the first stage shows the Epoch
- the second stage the Display Set
- the third stage the Display Set.
- the functional segment shown in the third row of FIG. 4A is drawn in the fourth row.
- the first stage Epoch refers to one period that has continuity of memory management on the AVClip playback time axis, and a data group assigned to this period.
- the memory assumed here is a graphics plane for storing graphics objects constituting a display, and an object buffer for storing uncompressed graphics objects.
- the continuity of memory management for these means that no flushing of the graphics plane and object buffer occurs during the period of this Epoch, and only within a certain fixed rectangular area in the graphics plane. (Note that flash means clearing all stored contents of planes and buffers.)
- O The vertical and horizontal sizes and positions of this rectangular area are as follows. It is fixed throughout the Epoch period. As long as graphics are erased and redrawn in the fixed area on the graphic plane, seamless reproduction is guaranteed.
- Epoch is a unit on the playback time axis that can guarantee seamless playback. If you want to change the area where graphics are to be erased / redrawn on the graphic plane, you must define the change time point on the playback time axis, and make a new Epoch after the change time point. In this case, seamless playback is not guaranteed at the boundary between the two Epochs!
- the seamless reproduction means that the graphics erasing and redrawing power is completed with a predetermined number of video frames.
- the number of video frames is 4,5 frames.
- the size of the video frame is determined by the ratio of the size of the fixed area to the entire graphic plane and the transfer rate between the object buffer and the graphic plane.
- the second-stage Display Set (abbreviated as DS) is a multi-function set that constitutes a graphics stream. Segment that realizes one screen configuration.
- the dashed line hkl in FIG. 5 indicates which Epoch the Display Set in the second row belongs to.
- the third row shows the type of Display Set.
- the type of Display Set at the beginning of Epoch is Epoch Start.
- the type of Display Set that is not the first is “Acquisition Point J,“ Normal Case ”,“ Epoch Continue ””.
- ⁇ 3 is only an example. There may be.
- Epoch Start is a Display Set that starts a new Epoch. Epoch Start therefore includes all the functional segments needed for the next screen composition.
- the Epoch Start is located at a location known to be cueed, such as a chapter in a movie.
- “Acquisition Point” is a Display Set that is not at the start of the Epoch but contains all the functional segments needed for the next screen composition. If cueing is performed from the Acquisition Point DS, graphics display can be realized without fail. In other words, the DS, which is the Acquisition Point, has the role of enabling the screen composition of the power during the Epoch.
- the Display Set which is an Acquisition Point, is incorporated at a position where it can be searched.
- locations include locations that can be specified by a time search.
- Time search is an operation that accepts a user's input of a time input of minutes and seconds and finds a reproduction time point corresponding to the input time. Since the time input is performed in rough units, such as 10 minutes or 10 seconds, the playback position at 10 minute intervals and the playback position at 10 second intervals can be specified by time search.
- Normal Case is a DS that has a display effect of "display update” and includes only the difference from the previous screen synthesis. For example, a DSv has the same contents as the preceding DSu. If the configuration is different from the preceding DSu, a DSv with ICS only or a DSv with ODS only is provided and this DSv is made a DS of Normal Case, which eliminates the need to provide duplicate ODS. This can contribute to a reduction in the capacity of the BD-ROM. Since the DS of Case is only a difference, the screen composition cannot be made by Normal Case alone.
- Epoch Continue indicates that the Epoch is continuous! / At the boundary of the AVClip. If the composition state of one DSn is set to Epoch Continue, it belongs to the same Epoch even if it exists on a different AVClip from the DSn-1 located immediately before it. Since these DSn and DSn-l belong to the same Epoch, flushing of the graphics plane and object buffer does not occur even if the AVClip branch occurs between these two DSs.
- a broken line kzl in the figure indicates an attribute relationship to which DS the fourth-stage functional segment belongs. Since the function segments in the fourth row are the same as those shown in FIG. 4 (a), it can be seen that a series of these functional segments in FIG. 4 (a) belong to Epoch Start. The functional segments belonging to Acquisition Point are the same as those belonging to Epoch Start, and the functional segments belonging to Normal Case are those in which a part of those belonging to Epoch Start is omitted.
- An Epoch is a period in which memory management is continuous on the playback time axis. Since an Epoch is composed of one or more Display Sets, the problem is how to assign a Display Set to the AVClip playback time axis.
- the playback time axis of the AVClip refers to an assumed time axis for defining the decoding timing and playback timing of individual picture data constituting the video stream multiplexed on the AVClip. On this playback time axis, the decode timing and playback timing are expressed with a time accuracy of 90 KHz.
- the DTS and PTS added to the ICS and ODS in the Display Set indicate the timing at which synchronous control should be realized on this playback time axis.
- Synchronous control using DTS and PTS added to the ICS and ODS is the assignment of Display Sets to the playback time axis.
- FIG. 6 is a diagram showing a playback time axis of an AVClip to which DSn is assigned.
- the beginning of DSn is indicated by the DTS value of the ICS belonging to DSn (DTS (DSn [ICS] >>).

- PTS (DSn [ICS]) is the time required for ODS decoding in DTS (DSn [ICS]).
- a period mcl in FIG. 6 indicates a period during which an arbitrary ODS (ODSm) belonging to DSn is decoded.
- the start point of this decoding period is indicated by DTS (ODSn [ODSm]), and the end point of this decoding is indicated by PTS (ODSn [ODSm]).
- Epochs are defined by performing the above-described assignment to the playback time axis for all ODSs belonging to the Epochs. This concludes the description of the assignment to the playback time axis.
- the present embodiment is characterized in that the behavior of the multi-page menu is controlled in accordance with the progress of the reproduction of the moving image on the reproduction time axis described above.
