What is JPEG?

JPEG is the abbreviation of “Joint Photographic Expert Group.” JPEG is a still-picture data compression system.

On a JPEG disc, each still picture is recorded as a file, which usually belongs to a Group (folder).

● Some files on a JPEG disc may be played back distortedly.

● Because of the disc characteristics or recording condition,

some discs may not be played back or it takes time to start

playback.

● The unit does not support “packet writing” discs.

● If there are any Files which are stored on a disc directly and do

not belong to any Group (directory), the unit recognized them

as belonging to an independent Group.

● The unit plays back Groups/Files on an JPEG disc in the

alphabetical order.

JPEG disc

File A.jpg

File B.jpg

File C.jpg

Group 2

Group 4

Group 1

File D.jpg

File E.jpg

File F.jpg

● For example, if there are three title Groups [one], [two] and

[three] on a disc, the playback order is [one], [three] then

[two]. Files in a Group are played back in the same way.

● Therefore, an JPEG disc on the market may be played back in

the different order from the order printed on its sleeve.

JPEG control display

The JPEG control display appears on the TV screen and playback starts when a JPEG disc is loaded.

Total group number on	Current file	Total file number in
disc	number	current group

Group 3
This unit can recognize up to 99 Groups and up to 150 Files per
Group.
If a disc includes more than the Files above limit, the unit stops
detecting Files when the number of detected Files reaches the
limit and ignores the subsequent Files. The unit also ignores any
non-JPEG file in the disc.
NOTES for making a private JPEG disc using a CD-R/
CD-RW disc:
● Select “ISO9660” as the disc format.
● Finalize the disc.	Current group	Current file	Total file number on
