Jingle Player
This unit contains a Jingle player with a one-shot mode for teasers and a scheduled mode for com-
mercial purposes (like playing advertisements in a certain sequence). To make use of the feature, the
user must create a folder named “Jingles” on the solid state memory media. The folder must have
exactly this name (with capital J and lower case following letters) and will not be available for choice
during normal replay.
The jingle files stored in this folder have to be prepared with specific names as well, and have to follow
the structure jx_yy with x from 1...3 and yy from 00 to 99. In this format, x defines the jingle number
(with a maximum of 3 jingles allowed) and yy being the number of minutes of background music the
jingle is followed by in scheduled jingle play mode. As an example, three jingles could be named
j1_01.mp3, j2_04.mp3 and J3_05.mp3. These three jingles will then be available for direct one-shot
play on pressing the jingle buttons (19), with each jingle assigned to the relative button.
A scheduled jingle play mode can be activated by pressing the J1 button for longer than 2 seconds,
allowing the jingles to be inserted into the program in an automatic sequence with a certain duration
of background music in between. The jingle replay would in the above example start immediately with
Jingle 1 followed by 1 minute of background music, then Jingle 2 followed by 4 minutes of background
music, then jingle 3 followed by 5 minutes of background music; after this, the sequence would loop.
If less jingles are stored in the Jingles folder, the loop runs after the last available jingle. As another
example, if only one jingle named j1_02 is stored in the Jingles folder, then this would mean the jingle
would play every 2 minutes in scheduled jingle pay mode.
Notes on files, folders and data conventions
The media player section build into this unit is a hardware player and as such subject to various
restrictions, which are useful to be aware of:
Media Memory types. The player only works with SD cards and USB sticks up to 16GB of size
which are formatted in FAT32 file system and contain a maximum of 2000 files. The player does
NOT support larger memory sizes, external hard disks or any media with NTFS formatting.
Media File types. The player’s replay ability from solid state memory media is limited to MP3 files
in MPEG 1 Layer 3, MPEG 2 Layer 3, MPEG 2.5 Layer 3 standard, with sample rates of
128/160/192/224/256/320 kbps + VBR. Any other files existing on the solid state memory
media will be ignored and are not available for replay.
File/Folder Structure. The player only allows a two-layer folder structure on the solid state media
memory, meaning a root layer and a folder layer, but not any cascaded folder-in-folder structures.
Such subfolders will be ignored and their content is not available for replay. Playable files located in
the root layer are displayed in a folder named “ROOT” although this folder does not physically exist
on the solid state memory media.
Folder Sorting. Folders are displayed in the sequence of their creation dates on the solid state
memory media. If a specific sequence is needed, then the folder shall be created in this sequence
on the memory media before copying any MP3 files into them.
File Sorting. Files are sorted alphanumerically, but due to file system limitations, the sorting is
limited to the first 8 digits. This may in some cases - where the first 8 digits are identical - lead to
a random-looking, not alphabetical sorting sequence of files.
File system cache. In order to allow relatively quick access to the file directory during navigation,
the player loads a copy of the file directory into its own memory upon insertion of the solid state
memory media. This loading process requires some time, during which the display shows a count-
down. The time required is about 4 seconds per 100 tracks with a maximum of 2000 tracks
(meaning Max. 80 seconds loading time).
Displayed File/Folder names. MP3 files are displayed with the first 30 digits of their file names in
a scrolling manner; digits exceeding the first 30 will be ignored. Note that the display data is the
file name and NOT the ID3 tag of the file. Folders are displayed with the first 10 digits of their
names, any exceeding digits will be ignored.
