JVC DD-1 ユーザーズマニュアル

• The following discs cannot be played back:
• DVD-ROM (except for MP3/WMA/JPEG/ASF/

DivX/MPEG1/MPEG2 format), DVD-RAM, CD-
ROM, CD-I (CD-I Ready), Photo CD, SACD, etc.

• Playing back these discs will generate noise and 

damage the speakers.

• Damaged discs and discs in an extraordinary 

shape (other than a disc of 12 cm or 8 cm in 
diameter) cannot be played back.

• JVC does not guarantee the operation and 

sound quality of discs not authorized by CD-DA, 
which is a CD specification. 
Before playback, confirm that the disc complies 
with this CD specification by checking the marks 
and reading notes printed on the package. 

• CDs recorded in the ISO 9660 format are play-

able (except CDs recorded in the “packet write” 
format (UDF format)).

• CDs recorded in the multi-session format are 

also playable.

• Files with an extension of “.mp3”, “.wma”, “.wav”, 

“.jpg”, “.jpeg”, “.asf”, “.divx”, “.div”, “.avi”, “.mpg” 
or “.mpeg” (extensions with uppercase and low-
ercase letters mixed are also acceptable) are 
playable.

• This system cannot play back DVDs recorded in 

multi-session or multi-border format.

• A disc may not be played back, or reading it may 

take a long time depending on its recording con-
ditions or properties.

• The time needed for reading varies with the 

number of groups or tracks (files) recorded on 
the disc.

• If a character other than single byte English 

characters is used in the file name of an MP3/
WMA/JPEG/ASF file, the track/file name will not 
be displayed correctly.

• The order of tracks/groups displayed on the 

MP3/WMA menu screen, and the order of files/
groups displayed on the JPEG menu screen 
may be different from that of files/folders dis-
played on a computer monitor screen.

• In the case of MP3/WMA discs, since groups/

tracks are played back in alphabetical order, a 
commercially available MP3/WMA disc may be 
played back in an order different from that indi-
cated on the label attached to the disc.

• Playing back an MP3/WMA file including a still 

image may take a long time. The elapsed time is 
not displayed until playing back starts. If playing 
back starts, the elapsed time may not be dis-
played correctly.

• For an MP3/WMA file, a disc with a sampling fre-

quency of 44.1 kHz and transmission rate of 
128 kbps is recommended.

• This system is not compatible with MP3i or 

MP3PRO.

• This system can play back a baseline JPEG file, 

excluding monochromatic JPEG files.

• This system can play back JPEG data taken with 

a digital camera conforming to the DCF (Design 
Rule for Camera File System) standard (when a 
function is applied such as the automatic rotation 
function of a digital camera, data goes beyond 
the DCF standard, so the image may not be dis-
played).

• If data has been processed, edited and restored 

with computer image editing software, the data 
may not be displayed.

• This system cannot play back animations such 

as MOTION JPEG, still pictures (TIFF etc.) other 
than JPEG, or image data with sound.

• The resolution of 640 x 480 pixels is recom-

mended for JPEG files. If a file has been 
recorded at a resolution of more than 640 x 480 
pixels, display may take a long time. An image 
with a resolution of more than 8 192 x 7 680 pix-
els cannot be displayed.

• The system supports ASF files recorded with the 

maximum bit rate of 384 kbps and an audio 
coder decoder of G.726. 

• For a WAV file, a disc with a sampling frequency 

of 44.1 kHz and a transmission rate of 16 bits is 
recommended. 

• This system does not support a disc recorded in 

multi-border format. 

• This system does not support a disc recorded in 

DVD VR format.
