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 manual.

Note 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 PICTURE preference display

(see page 51).

About JPEG discs

On a JPEG disc, each picture is recorded as a file. Files

are sometimes grouped into folders by category, etc.

Folders can exist within other folders, creating

hierarchical layers of folders. If you are familiar with

personal computers, the hierarchical file and folder

structure of a JPEG disc will be familiar to you as well.

This unit simplifies the hierarchical structure of a disc

and manages folders using "Groups," in the following

manner.

• A folder which has one or more files is regarded as a

Group.

• A folder which does not directly contain any files 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 display them. If there

are files other than JPEG files, they also count against

the 150-file total.

What is JPEG?

"JPEG" is an abbreviation for the Joint Photographic

Experts Group. "JPEG" is used to refer to an image file

format that utilizes a certain compression technique.

There are three sub-types of the JPEG format as

follows.

• baseline JPEG: used for digital cameras, the web,

etc.

• progressive JPEG: used for the web

• lossless JPEG: an old type, rarely used now

The 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 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 5/∞/2/3, numeric

buttons for controlling the unit.

NOTES for making your own JPEG disc

using a CD-R/CD-RW disc:

• 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).

NOTES

• 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.
