Playing MP3 Files
What is an MP3 file?
MP3 (MPEG-1 Audio Layer 3) is a file com-
pression standard prescribed by the ISO,
the International Standardization Organi-
zation and MPEG, which is a joint activity
institution of the IEC.
MP3 files contain compressed audio data.
MP encoding is capable of compressing
audio data at extremely high ratios, re-
ducing the size of music files to as much
as one-tenth their original size. This is
achieved while still maintaining near-CD
quality. The MP format realizes such
high compression ratios by eliminating the
sounds that are either inaudible to the hu-
man ear or masked by other sounds.
Compatible file systems
This device supports discs formatted
with ISO9660 level  or level 2. Under the
ISO9660 standard, there are some restric-
tions to remember. The maximum nested
folder depth is 8 (including the root di-
rectory). The number of characters for a
folder/file names are letters A-Z (all caps),
numbers 0-9, and ‘_’ (underscore). This
device also can play back discs in Joliet,
Romeo, etc., and other standards that con-
form to ISO9660. However, sometimes the
file names, folder names, etc., are not dis-
played correctly.
