discs, though there are some restrictions and differences.
			* Baseline JPEG format: Used for digital cameras, web, etc.
			Progressive JPEG format: Used for web.
What is JPEG?			Lossless JPEG format: An old type and rarely used now.
			● Some files on a JPEG disc may be played back distortedly.
JPEG is the abbreviation of “Joint Photographic Expert Group”.

usually belongs to a Group (folder).			● The unit does not support “packet writing” discs.
			● If there are any Files which are stored on a disc directly and do

		Group 1	● The unit plays back Groups/Files on a JPEG disc in the
	File B.jpg		alphabetical order.
			● For example, if there are three title Groups [one], [two] and
	File C.jpg		[three] on a disc, the playback order is [one], [three] then
JPEG disc			[two]. Files in a Group are played back in the same way.
			● Therefore, a JPEG disc on the market may be played back in
	Group 2		different order from the order printed on its sleeve.

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 on the disc.

NOTES for making a private JPEG disc using a CD-R/ CD-RW disc:

●Select “ISO 9660” as the disc format.

●Finalize the disc.
