Notes on all files

•The system can only recognize and play files with one of the following extensions, which can be in any combination of upper and lower case;

•MP3: “.MP3”, “.mp3”

•WMA: “.WMA”, “.wma”

•JPEG: “.JPG”, “.JPEG”, “.jpg”, “.jpeg”

•If a character other than single byte English characters is used in the file name of an MP3/WMA/JPEG file, the track/file name will not be displayed correctly.

•The system recognizes up to 150 tracks (files) per group, 99 groups per disc, and the total number of the tracks (files) that the system can play is 1 000.

•Some files may not be played back normally because of their disc characteristics or recording conditions.

Disc structure

DVD VIDEO

A DVD VIDEO consists of “titles” and each title may be divided into “chapters”.

Title 1 Title 2

Chapter 1 Chapter 2 Chapter 3 Chapter 1 Chapter 2

DVD AUDIO

For MP3/WMA files

•An off-the-shelf MP3 disc may be played in an order different from that indicated on the label attached to the disc.

•The system supports MP3/WMA files recorded with a bit rate of 32 – 320 kbps and a sampling frequency of 16 kHz, 22.05 kHz, 24 kHz (WMA only), 32 kHz, 44.1 kHz, or 48 kHz.

•If the tag information (album name, artist, and track title, etc.) is recorded on a disc, it appears in the file control display on the TV screen.

•We recommend to record each piece of material (song) at a sample rate of 44.1 kHz and at a data transfer rate of 128 (96 for WMA only) kbps.

•This system cannot play back files encoded with Multiple Bit Rate (MBR). (MBR is a format to encode a file content at several different bit rates.)

For JPEG files

•We recommend to record a file at 640 x 480 resolution.

•This system can play a baseline JPEG file, excluding monochromatic JPEG files.

•This system can play JPEG data taken with a digital camera conforming to the DCF (Design Rule for Camera File System) standard (when a function is applied such as the automatic rotation function of a digital camera, data goes beyond the DCF standard, so the image may not be displayed).

•If data has been processed, edited and restored with PC image editing software, the data may not be displayed.

•This system cannot play animations such as MOTION JPEG, or still images (TIFF etc.) other than JPEG, and image data with sound.

•An image with a resolution of more than 8 192 x 7 680 pixels cannot be displayed.

A DVD AUDIO consists of “groups” and each group may be divided into “tracks”.

Some discs include a “bonus group” that requires a password for playing (page 27).

Group 1 Group 2

Track 1 Track 2 Track 3 Track 1 Track 2

VCD/SVCD/CD

VCD, SVCD and CD consist of “tracks”.

In general, each track has its own track number. (On some discs, each track may also be further divided by indexes.)

Track 1 Track 2 Track 3 Track 4 Track 5

MP3/WMA [JPEG] discs

On an MP3/WMA [JPEG] disc, each still picture (material) is recorded as a track [file]. Tracks [Files] are usually grouped into a folder. Folders can also include other folders, creating hierarchical folder layers.

This unit simplifies the hierarchical construction of a disc and manages folders by “groups”.

Group 1 Group 2

Track 1	Track 2	Group 3	Group 4	Group 5
[File 1]	[File 2]

This product can recognize up to 1 000 tracks [files] in a disc. Also, the product can recognize up to 150 tracks [files] per group and up to 99 groups in a disc. Since the unit ignores the tracks [files] whose numbers are exceeding 150 and the groups whose numbers are exceeding 99, they cannot be played back.

•If there is any type of files other than MP3/WMA [JPEG] files in a folder, those files are also counted in the total file number.
