Region codes: Some DVD video discs
have a region code indicating which coun-
tries the DVD video disc can be played in
on this DVD player. If the DVD video disc
is not labeled as “ALL” or “1”, you cannot
use it on this DVD player. If you attempt to
play an inappropriate DVD video disc on
this player, “Region code error” appears
on the screen. Even if the DVD video disc
does not have a region code, there are
cases when it cannot be used.
■MARKS SHOWN ON DVD VIDEO
DISCS
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
level of restrictions of the country. The lev-
el of restrictions varies depending on the
DVD video disc. Some DVD video discs
cannot be played at all, or violent scenes
are skipped or replaced with other scenes.
• Level 1: DVD video discs for children can be played.
• Level 2 - 7: DVD video discs for children and G-rated movie can be played.
• Level 8: All types of the DVD video discs can be played.
Multi-angle feature : The same scene can
be enjoyed from different angles.
Multi-language feature : The subtitle and
audio language can be selected.
Region codes : The region codes are pro-
vided on DVD players and DVD discs. If
the DVD video disc does not have the
same region code as the DVD player, you
cannot play the disc on the DVD player.
For region codes, see page 210.

DVD VIDEO DISC GLOSSARY

1. AUDIO/VIDEO SYSTEM OPERATION
This is a general term that describes the
process of writing data on-demand to CD-
R, etc., in the same way that data is writ-
ten to floppy or hard discs.
This is a method of embedding track-
related information in an MP3 file. This
embedded information can include the
track title, the artist’s name, the album
title, the music genre, the year of produc-
tion, comments and other data. The con-
tents can be freely edited using software
with ID3 tag editing functions. Although
the tags are restricted to a number of
characters, the information can be viewed
when the track is played back.
WMA files can contain a WMA tag that is
used in the same way as an ID3 tag. WMA
tags carry information such as track title
and artist name.
This is the international standard for the
formatting of CD-ROM folders and files.
For the ISO 9660 format, there are two
levels 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.
