188 DVD VIDEO DISC GLOSSARY
DVD video discs: Digital versatile Disc that
holds video. DVD video discs have adopted
“MPEG2”, one of the world standards of digi-
tal compression technologies. The picture
data is compressed by 1/40 on average and
stored. Variable rate encoded technology in
which the volume of data assigned to the pic-
ture is changed depending on the picture for-
mat has also been adopted. Audio data is
stored using PCM and Dolby digital, which
enables higher quality of sound. Further-
more, multi−angle and multi−language fea-
tures will also help you enjoy the more ad-
vanced technology of DVD video.
Viewer restrictions: This feature limits what
can be viewed in conformity with a level of re-
strictions of the country. The level of restric-
tions varies depending on the DVD video
disc. Some DVD video discs cannot be
played at all, or violent scenes are skipped or
replaced with other scenes.
Level 1: DVD video discs for children can be
played.
Level 2 − 7: DVD video discs for children and
G−rated movie can be played.
Level 8: All types of the DVD video discs can
be played.
Multiangle feature: You can enjoy the
same scene at different angles.Multilanguage feature: You can select a
language of the subtitle and audio.
Region codes: The region codes are pro-
vided on DVD players and DVD discs. If the
DVD video disc does not have the same re-
gion code as the DVD player, you cannot play
the disc on the DVD player. For region codes,
see page 187.
Audio: This DVD player can play liner PCM,
Dolby digital and MPEG audio format DVD.
Other decoded type cannot be played.
Title and chapter: Video and audio pro-
grams stored in DVD video disc are divided in
parts by title and chapter.
Title: The largest unit of the video and audio
programs stored on DVD video discs. Usual-
ly, one piece of movie, one album, or one au-
dio program is assigned as a title.
Chapter: The unit smaller than that of title. A
title comprises plural chapters.

NOTICE
To ensure correct audio/video system
operations:
Be careful not to spill beverages over
the audio system.
Do not put anything other than a disc
into the slot.
Do not put anything other than an ap-
propriate disc into the DVD player.
The use of a cellular phone inside or
near the vehicle may cause a noise
from the speakers of the audio sys-
tem which you are listening to. How-
ever, this does not indicate a mal-
function.
RADIO RECEPTION
Usually, a problem with radio reception does
not mean there is a problem with your radio —
it is just the normal result of conditions outside
the vehicle.For example, nearby buildings and terrain
can interfere with FM reception. Power lines
or telephone wires can interfere with AM sig-
nals. And of course, radio signals have a lim-
ited range. The farther you are from a station,
the weaker its signal will be. In addition, re-
ception conditions change constantly as your
vehicle moves.
Here are some common reception problems
that probably do not indicate a problem with
your radio:
FM
Fading and drifting stations — Generally, the
effective range of FM is about 40 km (25
miles). Once outside this range, you may no-
tice fading and drifting, which increase with
the distance from the radio transmitter. They
are often accompanied by distortion.
Multi−path — FM signals are reflective, mak-
ing it possible for two signals to reach your an-
tenna at the same time. If this happens, the
signals will cancel each other out, causing a
momentary flutter or loss of reception.
Static and fluttering — These occur when sig-
nals are blocked by buildings, trees, or other
large objects. Increasing the bass level may
reduce static and fluttering.Station swapping — If the FM signal you are
listening to is interrupted or weakened, and
there is another strong station nearby on the
FM band, your radio may tune in the second
station until the original signal can be picked
up again.
AM
Fading — AM broadcasts are reflected by the
upper atmosphere — especially at night.
These reflected signals can interfere with
those received directly from the radio station,
causing the radio station to sound alternately
strong and weak.
Station interference — When a reflected sig-
nal and a signal received directly from a radio
station are very nearly the same frequency,
they can interfere with each other, making it
difficult to hear the broadcast.
Static — AM is easily affected by external
sources of electrical noise, such as high ten-
sion power lines, lightening, or electrical mo-
tors. This results in static.

190 CARING FOR YOUR CD CHANGER, DVD
PLAYER AND DISCS
Your CD changer is intended for use with
12 cm (4.7 in.) discs only.
Extremely high temperatures can keep
your CD changer and DVD player from
working. On hot days, use the air condi-
tioning to cool the vehicle interior before
you use the changer and player.
Bumpy roads or other vibrations may
make your CD changer and DVD player
skip.
If moisture gets into your CD changer and
DVD player, you may not play even
though they appear to be working. Re-
move the disc from the changer and play-
er and wait until it dries.
CAUTION
CD changers and DVD players use an in-
visible laser beam which could cause
hazardous radiation exposure if di-
rected outside the unit. Be sure to oper-
ate the changers and players correctly.

CorrectWrong
Handle discs carefully, especially when
you are inserting them. Hold them on the
edge and do not bend them. Avoid getting
fingerprints on them, particularly on the
shiny side.
Dirt, scratches, warping, pin holes, or oth-
er disc damage could cause the player to
skip or to repeat a section of a track. (To
see a pin hole, hold the disc up to the
light.)
Remove discs from the players when you
are not using them. Store them in their
plastic cases away from moisture, heat,
and direct sunlight.
6U5142a
To clean a compact disc: Wipe it with a soft,
lint−free cloth that has been dampened with
water. Wipe in a straight line from the center
to the edge of the disc (not in circles). Dry it
with another soft, lint−free cloth. Do not use
a conventional record cleaner or anti−static
device.MP3/WMA FILES
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
compatible 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 appropri-
ate file extensions.
Multi−session compatible CDs can
also be played.
MP3 files are compatible with the ID3
Tag Ver.1.0, Ver.1.1, and Ver.2.3 for-
mats. The unit cannot display disc
title, track title and artist name in oth-
er formats.

193
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, artist name.
The emphasis function is available
only when playing MP3/WMA files re-
corded at 32, 44.1 and 48 kHz. (The
system can play MP3 files with sam-
pling frequencies of 16, 22.05, and 24
kHz. However, the emphasis function
is not available for files recorded at
these frequencies.)
The sound quality of MP3/WMA files
generally improves with higher bit
rates. In order to achieve a reason-
able level of sound quality, discs re-
corded with a bit rate of at least 128
kbps are recommended.
Playable bit rates
MP3 files:
MPEG1 LAYER3—64 to 320 kbps
MPEG2 LSF LAYER3—64 to 160 kbps
WMA files:
Ver7, 8 CBR—48 to 192 kbps
Ver9 CBR—48 to 320 kbps
The MP3/WMA player does not play
back MP3/WMA files from discs re-
corder using packet write data transfer
(UDF format). Discs should be re-
corded using “pre−mastering” software
rather than packet−write software.
M3u playlists are not compatible with
the audio player.
MP3i (MP3 interactive) and MP3PRO
formats are not compatible with the
audio player.
The MP3 player is compatible with
VBR (Variable Bit Rate).
When playing back files recorded as
VBR (Variable Bit Rate) files, the play
time will not be correctly displayed if
fast−forward or reverse operations are
used.
It is not possible to check folders that
do not include MP3/WMA files.
MP3/WMA files in folders up to 8 lev-
els deep can be played. However, the
start of playback may be delayed
when using discs containing numerous
levels of folders. For this reason, we
recommend creating discs with no
more than two levels of folders.

The play order of the compact disc
with the structure shown on the left is
as follows:
MP3 player (rear seat entertainment sys-
tem)
001.mp3 002.mp3 . . . 006.mp3
MP3/WMA player (front audio system)
001.mp3 002.wma . . . 006.mp3
MP3 player (rear seat entertainment
system)—It is possible to play up to
253 folders on one disc.
MP3/WMA player (front audio sys-
tem)—It is possible to play up to 192
folders or 255 files on one disc.
The order changes depending on the
PC and MP3/WMA encoding software
you use.
CDR and CDRW discs
CD−R/CD−RW discs that have not been
subject to the “finalizing process” (a pro-
cess that allows discs to be played on a
conventional CD player) cannot be
played.
It may not be possible to play CD−R/CD−
RW discs recorded on a music CD record-
er or a personal computer because of disc
characteristics, scratches or dirt on the
disc, or dirt, condensation, etc. on the
lens of the unit.
It may not be possible to play discs re-
corded on a personal computer depend-
ing on the application settings and the en-
vironment. Record with the correct
format. (For details, contact the appropri-
ate application manufacturers of the ap-
plications.)
CD−R/CD−RW discs may be damaged by
direct exposure to sunlight, high tempera-
tures or other storage conditions. The unit
may be unable to play some damaged
discs.
If you insert a CD−RW disc into the
MP3/WMA player, playback will begin
more slowly than with a conventional CD
or CD−R disc.
Recordings on CD−R/CD−RW cannot be
played using the DDCD (Double Density
CD) system.TERMS
Packet write—
This is a general term that describes the pro-
cess of writing data on−demand to CD−R,
etc., in the same way that data is written to
floppy or hard discs.
ID3 Tag—
This is a method of embedding track−related
information in an MP3 file. This embedded in-
formation can include the track title, the art-
ist’s name, the album title, the music genre,
the year of production, comments and other
data. The contents can be freely edited using
software with ID3 tag editing functions. Al-
though the tags are restricted to the number
of characters, the information can be viewed
when the track is played back.
WMA Tag—
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, artist
name.

195 ISO 9660 format—
This is the international standard for the for-
matting of CD−ROM folders and files. For the
ISO 9660 format, there are two levels of regu-
lations.
Level 1:
The file name is in 8.3 format (8 character file
names, with a 3 character file extension. File
names must be composed of one−byte capi-
tal 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 ex-
tension). Each folder must contain fewer than
8 hierarchies.m3u—
Playlists created using “WINAMP” software
have a playlist file extension (.m3u).
MP3—
MP3 is an audio compression standard deter-
mined by a working group (MPEG) of the ISO
(International Standard Organization). MP3
compresses audio data to about 1/10 the size
of that on conventional discs.
WMA—
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.
