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”.
.
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 (A page 34).
VCD/SVCD/CD
VCD, SVCD and CD consist of “tracks”.
In general, each track has its own track number.
(On some discs, each track may also be further
divided by indexes.)
MP3/WMA/JPEG/ASF/DivX/MPEG1/MPEG2
discs
On an MP3/WMA/JPEG/ASF/DivX/MPEG1/
MPEG2 disc, each still picture (material) is
recorded as a track/file. 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 a disc and manages folders by “groups”.
This system can recognize up to 4 000 tracks/files
in a disc. Also, the system can recognize up to 150
tracks/files per group and up to 99 groups in a disc.
Since the system ignores tracks/files with numbers
exceeding 150 and groups with numbers
exceeding 99, these cannot be played back.
• If there is any type of files other than MP3/WMA/
JPEG/ASF/DivX/MPEG1/MPEG2 files in a
folder, those files are also counted in the total file
number.
