Sony DAV-X1 User Manual

MP3 is audio compression technology that 
satisfies the ISO/MPEG regulations. JPEG is 
image compression technology.

You can play back DATA CDs (CD-ROMs/CD-
Rs/CD-RWs) recorded in MP3 (MPEG1 Audio 
Layer 3) and JPEG format. However, the discs 
must be recorded according to ISO 9660 Level 
1, Level 2 or Joliet format for the system to 
recognize the tracks (or files). You can also play 
discs recorded in Multi Session.
See the instructions supplied with the CD-R/
CD-RW drives and the recording software (not 
supplied) for details on the recording format.

If MP3 audio tracks or JPEG image files are 
recorded in the first session, the system will also 
play MP3 audio tracks or JPEG image files in 
other sessions. If audio tracks and images in 
audio CD format or video CD format are 
recorded in the first session, only the first 
session will be played back.

• The system may not be able to play some DATA 

CDs. In this case, you cannot view the JPEG images 
recorded.

The system can play the MP3 audio tracks or 
JPEG image files:
• which have the extension “.MP3” (MP3 audio 

track) or “.JPG”/“.JPEG” (JPEG image file)

• which conform to the DCF* image file format

* “Design rule for Camera File system”: Image 

standards for digital cameras regulated by Japan 
Electronics and Information Technology Industries 
Association (JEITA).

• The system will play any data with the extension 

“.MP3,” “.JPG,” or “.JPEG” even if they are not in 
MP3 or JPEG format. Playing this data may generate 
a loud noise which could damage your speaker 
system.

• The system does not conform to audio in MP3PRO 

format.

The playback order of MP3 audio tracks or 
JPEG image files recorded on a DATA CD is as 
follows:

x Structure of disc contents

When you insert a DATA CD and press H, the 
numbered tracks (or files) are played 
sequentially, from 1 through 7. Any sub-
albums/tracks (or files) contained within a 
currently selected album take priority over the
