Jpeg Disc Playback; About Jpeg Discs - JVC XV-N5SL Instructions Manual

JPEG disc playback

The unit can play back JPEG files on a personally
recorded CD-R/RW disc. We refer to a disc that contains
JPEG files as a "JPEG disc" in this m anual.
N ote that if a disc contains both of MP3 and JPEG files,
you can only play back files of the type selected by the
MP3/JPEG setting in the PICT URE preference display
(see page 51).
What is JPEG?
"JPEG " is an abbreviation for the Joint Photographic
Experts Group. "JPEG " is used to refer to an im age file
form at that utilizes a certain co m pression technique.
There are three sub-types of the JPEG form at as
follo ws.
• baseline JPEG: used for digital ca m eras, the w eb,
etc.
• progressive JPEG: used for the w eb
• lossless JPEG: an old type, rarely used no w
The unit supports only the baseline JPEG form at;
Therefore, it cannot display pictures saved in the
progressive or lossless form ats. If a JPEG disc
contains JPEG files of non-baseline type, the unit
recognizes those files as JPEG files, the JPEG

files (the TV screen appears only in black).

About JPEG discs

O n a JPEG disc, each picture is recorded as a file. Files
are so m etim es grouped into folders by category, etc.
Folders can exist within other folders, creating
hierarchical layers of folders. If you are fa miliar with
personal co m puters, the hierarchical file and folder
structure of a JPEG disc will be fa miliar to you as w ell.
This unit sim plifies the hierarchical structure of a disc
and m anages folders using " Groups," in the follo wing
m anner.
• A folder w hich has one or m ore files is regarded as a
Group.
• A folder w hich does not directly contain any files is
ignored.
• Files w hich 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
m axim u m nu m bers and cannot display the m. If there
are files other than JPEG files, they also count against
the 150-file total.

• Select "ISO 9660" as the disc format.
• Finalize the disc after completing recording.
• We recommend you record your material at a 640 x 480
pixel resolution.
• This unit supports only the baseline JPEG format.
Therefore, it cannot display pictures saved in the
progressive or lossless formats. 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 show 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).
• The unit does not support "packet writing" discs.
• If the disc is recorded with multiple sessions, the unit
supports up to five sessions.
• The unit may not be able to read some discs, or may take a
long time to display a picture on the disc, due to disc
characteristics or recording conditions.
• Programmed and random playback functions do not
work with JPEG discs.
• The screen saver function will be activated if the same
picture is displayed for more than 5 minutes except
during slide show playback (see page 45).
• The unit only can play back files with the following file
extensions; ".jpg," ".jpeg," ".JPG," ".JPEG" and any
other combination of upper case and lower case letters
(such as ".Jpg").
• If a JPEG file name includes any 2-byte character, the
unit may not show the file name correctly.
• If a picture has been saved at greater than 640 x 480
pixel resolution, it may take some time to display the
picture.
• The unit will not accept any commands (stopping
playback, zooming in or out of an image, etc.) while in
the process of displaying a picture.
• The time required to read the disc contents may vary for
different discs, depending on the numbers of Groups
(folders) and files recorded, etc.
• If you attempt to display a non-baseline JPEG image:
The unit will not be able to display the picture (the TV
screen will be black). Other operations (stopping
display, selecting a file, etc.) will be possible, but may
take a long time.
• While a JPEG disc is loaded, you cannot bring up any
preference display (see page 48).
• This unit does not support pixel size picture of more
than 2400 pixels. Make sure that the picture pixel size is
2400 pixels or less.
