JPEG disc playback

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
•baseline JPEG: used for digital cameras, web, etc.
•progressive JPEG: used for web
•lossless 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 lossless). If a JPEG disc contains JPEG files of

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.

NOTES for making a private JPEG disc using a
•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 lossless). If a JPEG disc contains JPEG files of
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
•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
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.)
