DVD video disc information
DVD video discs
A DVD video disc is a Digital Versatile Disc that holds video. DVD video
discs have adopted “MPEG2”, one of the world standards of digital com-
pression technologies. The picture data is compressed by 1/40 on average
and stored. Variable rate encoded technology in which the volume of data
assigned to the picture is changed depending 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-lan-
guage features will also help you enjoy the more advanced technology of
DVD video.
Viewer restrictions
This feature limits what can be viewed in conformity with the level of
restrictions of the country. The level 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 movies can be
played.
Level 8: All types of DVD video discs can be played.
Multi-angle option
You can enjoy the same scene from different angles.
Multi-language option
You can select the subtitle and audio languages.
Region codes
The region codes are provided on DVD players and DVD discs. If the DVD
video disc does not have the same region code as the DVD player, you can-
not play the disc on the DVD player. (P. 558)
Audio
This DVD player can play linear PCM, Dolby Digital and MPEG audio for-
mat DVDs. Other decoded types cannot be played.

Title and chapter
Video and audio programs stored in DVD video discs are divided into parts
by title and chapter.
Title: The largest unit of the video and audio programs stored on DVD
video discs. Usually, one movie, one album, or one audio program is
assigned as a title.
Chapter: A title is comprised of one or more chapters.
Sound
Dolby Digital
Manufactured under license from Dolby Laboratories. Dolby and the double-
D symbol are trademarks of Dolby Laboratories.
MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1/10 of their original size by using
MP3 compression.
WMA (Windows Media Audio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3 for-
mat.
There is a limit to the MP3 and WMA file standards that can be used and to
the media/formats on which the files are recorded.

File names
The only files that can be recognized as MP3/WMA and played are those
with the extension .mp3 or .wma.
Discs containing multi-session recordings
As the audio system is compatible with multi-sessions, it is possible to play
discs that contain MP3 and WMA files. However, only the first session can
be played.
ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track
title, artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3 ID3 tags.
(The number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the
track title and artist name in the same way as with ID3 tags.
MP3 and WMA playback
When a disc containing MP3 or WMA files is inserted, all files on the disc
are first checked. Once the file check is finished, the first MP3 or WMA
file is played. To make the file check finish more quickly, we recommend
you do not write in any files other than MP3 or WMA files or create any
unnecessary folders.
Discs that contain a mixture of music data and MP3 or WMA format data
cannot be played.
Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and
WMA files, they may be mistakenly recognized and played as MP3 and
WMA files. This may result in large amounts of interference and damage
to the speakers.

GS450h_300h_OM_OM30D53E_(EE)
Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit
rate of at least 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be possible in some instances,
depending on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3
and WMA files on the market, and depending on the status of the encod-
ing and the file format, poor sound quality or noise at the start of play-
back may result. In some cases, playback may not be possible at all.
• When files other than MP3 or WMA files are recorded on a disc, it may
take more time to recognize the disc and in some cases, playback may
not be possible at all.
• Microsoft, Windows, and Windows Media are the registered trademarks
of Microsoft Corporation in the U.S. and other countries.
CAUTION
DVD video precaution
Conversational speech on some DVDs is recorded at a low volume to
emphasize the impact of sound effects. If you adjust the volume assuming
that the conversations represent the maximum volume level that the DVD
will play, you may be startled by louder sound effects or startled when you
change to a different audio source.
Loud sounds may have a significant impact on the human body or pose a
driving hazard. Keep this in mind when you adjust the volume.
