6. TIPS FOR OPERATING THE AUDIO/VISUAL SYSTEM
IS250/350_Navi_U
zThis is the international standard for the for-
matting of CD-ROM folders and files. For
the ISO 9660 format, there are 2 levels of
regulations.
z 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 capital letters and numbers. The
“_” symbol may also be included.)
z Level 2: The file name can have up to 31
characters (including the separation mark
“.” and file extension). Each folder must
contain fewer than 8 hierarchies.
z Playlists created using “WINAMP” soft-
ware have a playlist file extension (.m3u).
z MP3 is an audio compression standard
determined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). MP3 compresses audio data to about
1 /10 the size of that on conventional discs. z
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 decod-
ing formats for WMA files are Ver. 7, 8 and
9.
z AAC is short for Advanced Audio Coding
and refers to an audio compression tech-
nology standard used with MPEG2 and
MPEG4.
