DVD video discs: Digital Versatile Disc
that holds video. DVD video discs have
adopted “MPEG2”, one of the world
standards of digital compression tech-
nologies. The picture data is com-
pressed by 1/40 on average and stored.
Variable rate encoded technology in
which the volume of data assigned to the
picture is changed depending on the pic-
ture format has also been adopted. Au-
dio data is stored using PCM and Dolby
Digital, which enables higher quality of
sound. Furthermore, multi-angle and
multi-language features will also help
users enjoy the more advanced technol-
ogy of DVD video.
Viewer restrictions: This feature limits
what can be viewed in conformity with
a level of restrictions of the country. The
level of restrictions varies depending on
the DVD video disc. Some DVD video
discs cannot be played at all, or violent
scenes are skipped or replaced with oth-
er scenes.
• Level 1: DVD video discs for children
can be played.
• Level 2 - 7: DVD video discs for chil-
dren and G-rated movie can be
played.
• Level 8: All types of the DVD video
discs can be played.
Multi-angle feature: The same scene
can be enjoyed from different angles.
Multi-language feature: The subtitle and
audio language can be selected.Region codes: The region codes are pro-
vided on DVD players and DVD discs.
If the DVD video disc does not have the
same region code as the DVD player,
you cannot play the disc on the DVD
player. For region codes, see page 266.
Audio: This DVD player can play liner
PCM, Dolby Digital and MPEG audio
format DVDs. Other decoded types can-
not be played.
Title and chapter: Video and audio pro-
grams stored in DVD video discs are di-
vided into parts by title and chapter.
Title: The largest unit of the video and
audio programs stored on DVD video
discs. Usually, one movie, one album,
or one audio program is assigned as a ti-
tle.
Chapter: A unit smaller than that of title.

MP3 (MPEG Audio Layer 3) and
WMA (Windows Media Audio) are
audio compression standards.
The MP3/WMA player can play MP3
and WMA files on CD-ROM, CD-R
and CD-RW discs.
The unit can play disc recordings com-
patible with ISO 9660 level 1 and level
2 and with the Romeo and Joliet file
system.
When naming an MP3 or WMA file,
add the appropriate file extension (.mp3
or .wma).
The MP3/WMA player plays back files
with .mp3 or .wma file extensions as
MP3 or WMA files. To prevent noise
and playback errors, use the appropriate
file extensions.
The MP3/WMA player can play only
the first session when using multi-ses-
sion compatible CDs.
MP3 player: MP3 files are compatible
with the ID3 Tag Ver. 1.0, Ver. 1.1, Ver.
2.2 and Ver. 2.3 formats. The unit can-
not display disc title, track title and art-
ist name in other formats.
USB memory: MP3 files are compati-
ble with the ID3 Tag Ver. 1.0, Ver. 1.1,
Ver. 2.2, Ver. 2.3 and Ver. 2.4 formats.
The unit cannot display track title and
artist name in other formats.
WMA files can contain a WMA tag
that is used in the same way as an ID3
tag. WMA tags carry information such
as track title and artist name.
The emphasis function is available only
when playing MP3/WMA files
recorded at 32, 44.1 and 48 kHz.MP3 files for MP3 player:
MPEG 1 LAYER 3 32, 44.1, 48 kHz
MPEG 2 LSF LAYER 3 16, 22.05,
24 kHz
MP3 files for USB memory:
MPEG 1 AUDIO LAYER 2, 3 32,

48 kHz
WMA files for USB memory:
Ver. 7, 8, 9 (9.1/9.2) CBR 32, 44.1,
48 kHz
The sound quality of MP3/WMA files
generally improves with higher bit
rates. In order to achieve a reasonable
level of sound quality, discs recorded
with a bit rate of at least 128 kbps are
recommended.

This is the international standard for the
formatting of CD-ROM folders and
files. For the ISO 9660 format, there
are 2 levels of regulations.
Level 1: The file name is in 8.3 format
(8 character file names, with a 3 charac-
ter file extension. File names must be
composed of one-byte capital letters
and numbers. The “_” symbol may also
be included.)
Level 2: The file name can have up to
31 characters (including the separation
mark “.” and file extension). Each
folder must contain fewer than 8 hierar-
chies.
Playlists created using “WINAMP”
software have a playlist file extension
(.m3u).
MP3 is an audio compression standard
determined by a working group
(MPEG) of the ISO (International Stan-
dard Organization). MP3 compresses
audio data to about 1/10 the size of that
on conventional discs.
WMA (Windows Media Audio) is an
audio compression format developed
by Microsoft
®. It compresses files into
a size smaller than that of MP3 files.
The decoding formats for WMA files
are Ver. 7, 8 and 9.
