4. Telbook aplicationback to top

To use the phone book function of the player, you will need a tool to generate a binary file to be imported by the player phone book application. If your player don't work with one version, it will work with other.

manufacturer tools:

Aur�lio's tool:

Aurélio wrote a "all in one" telbook file script in python that can generate the telbook file in both versions(1.0, 1.1 and 2.0), directly from a CVS contact list. You can export your contacts information from outlook, yahoo, gmail or any exportable source directly into the player.

You can download it here :

If you are a mac user, you can get a AppleScript to export the Address Book on Aurélo's page.

The .py file is a python script, so you must have the python libraries installed.

Instructions to Aur�lio's tool:

Just call it under the command prompt and inform the output version, the CVS format type and the CSV contact file:

python -v [2.0|1.1|1.0] -o [outlook|yahoo|kontact|any] [CVS contact file]


python -v 2.0 -o outlook contacts.csv

For the format type (-o), you can use any of the tree predefined formats (Outlook, yahoo, kontact) or you can set up your own format.

In this case, you will have to map the CVS data to be imported in a matrix(starting by 1). To join two or more fields in one, put them inside (parenthesis)

Matrix shall order the data in this order:
Full name, mobile phone, home phone, email, birthday date, work phone Example: 'yahoo':[ (1, 2, 3), 13, 9, 5, 33, 10 ]

  • (1,2,3) are the positions that together hold the "Full Name";
  • 13 is the position with holds the "mobile phone";
  • 9 is the position with holds the "home phone" and so on...
If you look at a yahoo generated CVS file, each line will be like this:
name1,name2,name3,,email,,,,home phone,work phone,,,mobile phone,,,,,,,,,,,,,,,,,,,birthday date, [...]
[1]  [2]   [3]     [5]      [9]        [10]         [13]                          [33]
So, for the yahoo CVS format, you can use this command(note that you can only use (parenthesis) if you edit the source): python -v 2.0 -o '1,13,9,5,33,10' contacts.csv or simply use the saved matrix on the source named 'yahoo': python -v 2.0 -o yahoo contacts.csv
