Data hierarchy

DVD VIDEO/DVD VR
A DVD VIDEO consists of "titles" and each title
may be divided into "chapters".
A DVD VR consists of "original programs" or "play
lists" and each original program/play list may be
divided into "chapters".
Title 1/Original program 1/
Play list 1
Chapter 1 Chapter 2 Chapter 3 Chapter 1 Chapter 2
DVD AUDIO
A DVD AUDIO consists of "groups" and each
group may be divided into "tracks".
Some discs include a "bonus group" that requires
a password for playback. (Refer to page 34.)
Group 1
Track 1 Track 2 Track 3
VCD/SVCD/CD
A VCD/SVCD/CD consists of "tracks".
In general, each track has its own track number.
(On some discs, each track may also be further
divided by indexes.)
Track 1 Track 2 Track 3
MP3/WMA/WAV/JPEG/ASF/DivX/MPEG1/
MPEG2 files
Audio, still pictures and video are recorded as
tracks/files on a disc or a USB device. Tracks/files
are usually grouped into a folder. Folders can also
include other folders, creating hierarchical folder
layers.
This system simplifies the hierarchical construction
of files and manages folders by "groups".
.
Up to 99 groups
Group 1
Track 1 Track 2 Group 3 Group 4 Group 5
/File 1 /File 2
Up to 999 tracks/files
This system can recognize up to 4 000 tracks/files
on a disc. Also, the system can recognize up to
999 tracks/files per group and up to 99 groups on a
disc. Since the system ignores the tracks/files with
numbers exceeding 999 and the groups with num-
bers exceeding 99, these cannot be played back.
If there are any type of files other than MP3/WMA/
WAV/JPEG/ASF/DivX/MPEG1/MPEG2 files on a
disc, those files are also counted in the total num-
ber of files.
