DVD VIDEO
A DVD VIDEO consists of “titles” and each title
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 playing (Apage 27).
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 [JPEG] discs
On an MP3 [JPEG] 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 unit simplifies the hierarchical construction of
a disc and manages folders by “groups”
This unit can recognize up to 150 tracks [files] per
group and up to 99 groups per disc (up to 14,850
files in total). Since the unit ignores the tracks
[files] whose numbers are exceeding 150 and the
groups whose numbers are exceeding 99, they
cannot be played back.
• If there is any type of files other than MP3 [JPEG]
files in a folder, those files are also counted in the
total file number.
