Phone Customization Data
In addition to the configurable aspects of the GUI discussed above, some of the data that drives the GUI can be
customized by the administrator of the phones. These data are collectively called Phone Customization Data which
include the following data types:
Customization Data
Type
Description
Internal Data Storage Path
Startup Splash Screen
The background picture shown on
screen when the phone is starting
up. The data file must be in 16bit
RGB565 raw format and the
filename must be logo.raw
/backgnd/logo.raw
Background Pictures

The pictures that can be chosen by
the user to show as wall paper

Startup Splash Screen
During cold boot, the phone looks for a custom splash screen
logo.raw
in the internal folder
/backgnd/
(the same folder
where custom background pictures are located).
logo.raw
must have a dimension of 480x272, and must be stored in 16 bits per pixel RGB565 format. An example of
converting a PNG file to a
logo.raw
on a Linux system is shown here:
avconv -vcodec png -i mylogo.png -vcodec rawvideo -f rawvideo -pix_fmt rgb565 logo.raw
The file size of
logo.raw
should always be 261120 bytes. A custom logo.raw can only be uploaded into the phone using
the customization data package upload method.
Background Pictures
Custom background pictures are stored in the internal folder
/backgnd/.
Each background picture should have the pixel
dimension 480Wx272H. JPEG, PNG, BMP, and GIF files are the acceptable file formats. All the pictures stored in this
folder will be made available to be selected by the user as background picture (i.e. wall paper) on the phone screen.
