DVD VIDEO and 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”.
VCD, SVCD and CD
A VCD, SVCD or 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.)
MP3, WMA, WAV, JPEG, ASF, DivX, MPEG1 and
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”.
.
This system can recognize up to 4000 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. Because the system ignores the tracks/files
with numbers exceeding 999 and the groups with
numbers exceeding 99, these cannot be played
back.
If there are any type of files other than MP3, WMA,
WAV, JPEG, ASF, DivX, MPEG1 or MPEG2 files
on a disc, those files are also counted in the total
number of files.
• Do not use a commercially-available non-stan-
dard shape disc (like a heart, flower or credit
card, etc.), because it may damage the system.
• Do not use a disc with tape, stickers, or paste on
it, because it may damage the system.
• Do not bend the disc.
• Scratches concentrated on a certain part cause
sound dropout.
• Be sure not to use thinners, benzenes, cleaners
for analog records, or other chemical agents.
