DVD video discs: Digital Versatile Disc
that holds video. DVD video discs have
adopted “MPEG2”, one of the world stan-
dards of digital compression technologies.
The picture data is compressed by 1/40 on
average and stored. Variable rate encoded
technology in which the volume of data as-
signed to the picture is changed depend-
ing on the picture format has also been
adopted. Audio data is stored using PCM
and Dolby Digital, which enables higher
quality of sound. Furthermore, multi-angle
and multi-language features will also help
users enjoy the more advanced technolo-
gy of DVD video.
Viewer restrictions: This feature limits
what can be viewed in conformity with a

el of restrictions varies depending on the

This is the international standard for the
formatting of CD-ROM folders and files.
For the ISO 9660 format, there are 2 lev-
els of regulations.
Level 1: The file name is in 8.3 format (8
character file names, with a 3 character
file extension. File names must be com-
posed of one-byte capital letters and num-
bers. The “_” symbol may also be
included.)
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.
Playlists created using “WINAMP” soft-
ware have a playlist file extension (.m3u).
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.
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.
