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 59).

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

TV DVD the remote control unit is set to "DVD" when using the 5//2/3, numeric buttons for controlling the unit.

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.

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 54).

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 into 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 57).

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.
