The unit can play back JPEG files on a private CD-R/RW
disc. We refer to a disc that contains JPEG files as a
"JPEG disc" in this manual.
Note that, if a disc contains both of MP3 and JPEG files,
you can only play back files of either type selected by the
MP3/JPEG setting in the PICTURE preference display
(See page 50).
What is JPEG?
"JPEG" is an abbreviation for the Joint Photographic
Experts Group and is an image format that utilizes a
compression technique.
There are three sub-types of the JPEG format as
follows.
• baseline JPEG: used for digital cameras, web, etc.
• progressive JPEG: used for web
• Iossless JPEG: an old type and rarely used now
The unit supports only the baseline JPEG type,
therefore, it cannot display pictures of the other types
(progressive and Iossless). If a JPEG disc contains
JPEG files of non-baseline type, the unit recognizes
those files as JPEG files, the JPEG CONTROL display
and the display window shows the information of the
contents (filename, file number, etc.), but you cannot
show the still pictures of those files (the TV screen
appears only in black.)
NOTE
Make sure that the TV - DVD switch on
the remote control unit is set to "DVD"
when using the A/V/4/I_, numeric
buttons for controlling the unit.
About JPEG disc
On an JPEG disc, each material (still picture) is recorded on
a file. Files may be grouped into a folder by category, etc. In
addition, a folder can be a member of another folder,
creating hierarchical folder layers. If you are familiar with a
personal computer, you may easily understand the
hierarchical file/folder construction of JPEG discs.
This unit simplifies the hierarchical construction of a disc
and manages folders by "Groups" in the following
manners.
• A folder which has one or more files is regarded as a
Group.
• A folders' folder which does not manage any file
directly is ignored.
• Files which do not belong to any folder are grouped
into "Group 1".
• The unit recognizes up to 150 files per Group, and up
to 99 Groups per disc. It ignores those exceeding the
maximum numbers and cannot play back them. If
there is any type of files other than JPEG files in a
folder, those files are also counted down from the total
number of 150.

_ up to 150 files per directory
NOTES for making a private JPEG disc
using a CD-R/CD-RW disc:
• Select "ISO 9660" as the disc format.
• Finalize the disc after completing recording.
• We recommend to record a material at "640 x 480"
resolution.
• The unit supports only the baseline JPEG type,
therefore, it cannot display pictures of the other types
(progressive and Iossless). If a JPEG disc contains JPEG
files of non-baseline type, the unit recognizes those
files as JPEG files, the JPEG CONTROL display and the
display window shows the information of the contents
(filename, file number, etc.), but you cannot show the
still pictures of those files (the TV screen appears only
in black.)
NOTES
• The unit does not support "packet write" discs.
• If the disc is recorded with multiple sessions, the unit
supports up to five sessions.
• Some disc may not be played back, or take some time to
open the whole picture because of the disc characteristics
or recording condition.
• You cannot playback files in the desired (programmed)
or random order.
• The screen saver function is activated while same
picture is displayed for more than 5 minutes except
during slide show playback (See page 44.)
• The unit only can play back files with any of the
following file extensions; ".jpg", ".jpeg", ".JPG",
".JPEG" and any uppercase and lowercase combination
(such as ".Jpg").
• If a JPEG file name includes any 2-byte character, the
unit may not show the file name correctly.
• When a picture resolution is more than "640 x 480", it
takes some time to open the whole picture.
• Carry out an operation after opening the whole
picture.The unit does not accept any operation
(Stopping the unit, zooming in/out a picture etc.) while
opening the picture.
• Time required for reading the disc contents differs with
discs, depending on the numbers of Groups (folders)
and files recorded, etc.
• If you play back a non-baseline JPEG file:
The unit cannot display the still picture of the file. (the
TV screen appears only in black.) In this case, other
operations (such as stopping playback, selecting a
file,etc.) are possible but may take a long time.
• While a JPEG disc is loaded, you cannot bring up any
preference display (See page 47.)
