Operations for JPEG discs are similar to those for Audio CD discs, though there are some restrictions and differences. 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). JPEG disc File A.jpg File B.jpg File C.jpg Group 1 Group 2 Group 4 File D.jpg File E.jpg File F.jpg 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. EN 65 NOTES: ● We recommend to record a file at 640 x 480 resolution. (If a file has been recorded at a resolution of more than 640 x 480, it will take a longer time to be displayed.) ● This unit supports the JPEG files whose resolution is 32 to 8192 pixel in width and 32 to 7680 pixel in height. ● This unit can only play back baseline JPEG files*. Progressive JPEG files* or lossless JPEG files* cannot be played back. * Baseline JPEG format: Used for digital cameras, web, etc. Progressive JPEG format: Used for web. Lossless JPEG format: An old type and rarely used now. ● 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. ● 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.
