Playing MP3 discs
What is MP3?
MP3 (MPEG-1 Audio Layer 3) is a
compression standard prescribed by the
ISO, the International Standardization
Organization and MPEG, which is a joint
activity institution of the IEC.
MP3 fi les contain compressed audio data.
MP3 encoding is capable of compressing
audio data at extremely high ratios,
reducing the size of music fi les to as much
as one-tenth their original size. This is
achieved while still maintaining near-CD
quality. The MP3 format realizes such
high compression ratios by eliminating
the sounds that are either inaudible to the
human ear or masked by other sounds.
Corresponding fi le systems
This device supports discs formatted
with ISO9660 level 1 or level 2. Under
the ISO9660 standard, there are some
restrictions to remember.
The maximum nested folder depth is 8
(including the root directory). The number
of characters for a folder/fi le 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 conform to ISO9660. However,
sometimes the fi le names, folder names,
etc., are not displayed correctly.
Playing a JPEG disc
When preparing a disc of jpeg images to be
shown using the DVD player, please note
that following guidelines:
• The recommended image size is 640 x
480 pixels. If a fi le is recorded at a higher
resolution, the player must resample it,
which will cause delays in displaying the
image.
• Only “baseline” type JPEG images can be
displayed on this player. Ths is the typical
format used in digital cameras and web
cameras.
“Progressive” (typically used for website
display) or “lossless” (an older format
which is rarely used today) JPEG fi les
cannot be played. So be sure you are
saving the fi les in the proper format. If
you play a progressive or lossless JPEG
image, a black screen will appear. When
you next select a baseline image, you may
experience some delays.
Playing MPEG discs
- This unit can play back MPEG 1 or 2 fi les
with the extension code <.mpg>.
- Audio stream should conform to MPEG1
Audio Layer 2.
Frequently Asked Questions
- I inserted a DVD disc, but it cannot be
played. The message “REGION ERROR”
is displayed.
DVD players and discs all have “REGION
CODES.” If the region code number on the
DVD disc does not correspond to the region
number of this DVD player, the unit cannot
play the disc.
- When I insert a DVD disc, there is a
window shown on the screen for me to
enter a 4 character password. Why?
The current disc has a “Parental Control”
level, and the player’s parental level is set
below the level of the disc. To view this disc,
you should enter the correct password to
play the disc normally.
NOTE:
To set the “Parental Control” level, please
refer to “Parental Control Level” on page 22.
