Specifications of files that can be played
To play a CD-R or CD-RW containing MP3/WMA or JPEG files with this
unit, the contents of the disc must conform to the following standards.
MP3/WMA
File system: ISO9660 level 1 or level 2
Discs that have been recorded in the packet write (UDF) format cannot be
read.
Bitrate: MP3: 32 kbps~320 kbps
WMA: 64 kbps - 160 kbps
Sampling frequency: 16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, 48 kHz
Filename: Half-width English characters only. Must bear the “.mp3” or “.wma” file
extension. Distinction between upper- and lowercase characters is not per-
formed.
Group (folder) count: up to 99
Track (file) count: up to 1000
Other: It is possible to play multi-session recorded discs.
MovieMate is not capable of Multiple Bit Rate (a file format containing audio
recorded in numerous different bit rates within the one file) playback.
JPEG
File system: ISO9660 level 1 or level 2
Discs that have been recorded in the packet write (UDF) format cannot be
read.
Filename: Half-width English characters only. Must bear the “.jpg” or “.jpeg” file
extension. Distinction between upper- and lowercase characters is not per-
formed.
Total number of pixels: Images containing up to 8192 x 7680 pixels can be read.
However, because it takes time to reproduce files with a resolution exceeding
640 x 480 pixels, it is recommended that images be saved at 640 x 480 pixels.
Group (folder) count: up to 99
Track (file) count: up to 1000
Other: It is possible to play multi-session recorded discs.
Only baseline JPEG is supported.
Monochrome JPEG files cannot be read.
Progressive JPEG and motion JPEG are not supported.
JPEG data created by a digital camera and conforming to the DCF (Design
rule for Camera File system) standard is supported. When certain digital cam-
era functions such as automatic rotation have been used, it is likely that the
data will not comply with the DCF standard. If this is the case, playback may
not be possible.
Notes on playback
• Depending on the recording and the characteristics of the disc it is possible that
the disc may not be readable, or that reading the disc may take some time.
• The time it takes to read a disc differs depending on the number of groups or
tracks (files) recorded on the disc.
• The order of the group/track (file) name list display and the order displayed on a
PC screen may be different.
• When playing commercially available MP3 discs, it is possible that playback
will be in a different order from the order described on the disc.
• It may take some time to play still pictures containing MP3 files. The time-
elapsed is not displayed until playback has begun. Further, there are times when
an accurate elapsed time is not displayed, even once playback has begun.
• It is possible that data that has been processed, edited, or saved using computer
image editing software might not play.
