Displaying MP3/WMA/AAC Tag titles

Tag information (track title, artist name, and
album title) can be displayed for an MP3/WMA/
AAC file containing the Tag information.
This system supports the ID3 TAG version 1.x/
2.x and WMA-TAG.

Note:
Tag information entered with 2-byte characters

may not be displayed properly on the display.

The ID3 version 2.x tag format is not completely

supported. This system can display information up
to 60 bytes, and ignores the rest.

Album titles of WMA-TAG may not be displayed

properly.

Precautions on the MP3/WMA/AAC
files

General precautions
• Files other than MP3/WMA/AAC format cannot

be played. In addition, some files may not be
played because of the encoding settings.
When a file cannot be played, the next file is
played instead.

• Some noise may occur depending on the type

of encoder software used to encode the data.

• You can apply the VBR (Variable Bit Rate)

format when encoding. In this case, the
displayed play time may be slightly different
from the actual play time.

• Files that the DRM (Digital Rights

Management) function is set cannot be played.

For MP3 files
• Set the Sampling Frequency to:

• MPEG1 Layer3: 32, 44.1, or 48 kHz
• MPEG2 Layer3: 16, 22.05, or 24 kHz
• MPEG2.5 Layer3: 8, 11.025, or 12 kHz

• Set the Bit Rate to:

• MPEG1 Layer3: 32 to 320 kbps (VBR)
• MPEG2 Layer3: 8 to 160 kbps (VBR)
• MPEG2.5 Layer3: 8 to 160 kbps (VBR)

• Add a file extension “.MP3” or “.mp3” using

single byte characters.

For WMA files
• Set the Sampling Frequency to within ranges

from 22.05 to 44.1 kHz.

• Set the Bit Rate to 48, 64, 80, 96, 128, 160, or

192 kbps.

• Add a file extension “.WMA” or “.wma” using

single byte characters.

For AAC files
• This system supports only the MPEG4 Audio

files encoded by the iTunes.

• Set the Sampling Frequency to 44.1 or 48 kHz.
• Set the Bit Rate to within ranges from 16 to 320

kbps (VBR).

• Add a file extension “.M4A” or “.m4a” using

single byte characters.

Precautions when preparing a disc

Note:
For details of the DivX file mentioned below, see

“DivX Operations” (page 33).

Logical format (File system)
The following writing formats are available when
writing MP3/WMA/AAC/DivX files on a disc:
• For CD-R/RW: ISO9660 level 1/level 2,

Romeo, Joliet, or Apple ISO (without including
expansion format)

• For DVD±R/RW: UDF (Universal Disk Format)
Folder structure
• The folder hierarchy must be within 8

hierarchical levels. Otherwise, playback will be
impossible.

• You can store the MP3 files, WMA files, and

AAC files together in a disc or folder.

• You can also store the MP3/WMA/AAC files

and DivX files together in a disc or folder. In
such a case, you can select whether the disc is
regarded as an MP3/WMA/AAC disc or as a
DivX disc. See “Setting the Playform of discs
recorded with DivX files” (page 33).

Number of files or folders
• The maximum allowable number of folders is

255 (including root directory).

• The maximum allowable number of files in a

folder is 255.

Folder representation in the folder list
• Only folders containing MP3/WMA/AAC files or

DivX files (

1 to 4 in illustration) are displayed

on the list. Folders containing no MP3/WMA/
AAC/DivX file are not displayed.

• Folder hierarchy (

1 to 4 in illustration) is

ignored, and unified into one level.

• Folders are arranged in the order of the folder

creation.
