Chapter 1 Introduction
Limited Support for MPEG-4
Limited Support for MPEG-4
DMP support for the MPEG-4 suite of standards does not extend to every possible aspect, entity, or
variant of MPEG-4. We require explicitly that:
• You use the MPEG-4 Part 2 codec.
• Audio and video in your MPEG-4 files are multiplexed in an MPEG-2 transport stream.
Supported Attributes for Digital Audio
We support the following attributes for digital audio in this release.
• Audio MPEG-1 Layers 1 and 2
• AAC (MPEG-4) Low Complexity
• AC-3 Compressed Audio
• Audio data rate: 64-320 kbps
Supported Filetypes in the Embedded Browser
A version of the Mozilla browser is preinstalled on each DMP 4305G device. The DMP browser is based
on Mozilla version
1.7.13 and supports JavaScript version 1.5.
The DMP browser can work with files of these types, but not with files of any other type:
• HTML
• TXT
• GIF
• JPEG
• PNG
• SWF (Flash 6 or Flash 7)
You cannot install browser plug-ins or any other software on your DMP, whether to support additional
filetypes or for any other purpose. No Java Runtime Environment (JRE) is installed.
Understanding the Difference Between ‘Apply’ and ‘Save’
The graphical user interface for DMPDM contains elements that help you to activate any change that you
make, and it is important that you understand the difference between activating a change temporarily or
doing so permanently.
• To confirm that you are satisfied with changes that you made to the values for a condition or setting,
click Apply. After you click Apply, the changes take effect. However, the changes are temporary
and the previously defined values for the pertinent condition or setting will return as soon as the next
time that your DMP restarts.
• To put all changed values into effect permanently, so that they persist even after your DMP restarts,
select Administration
> Save Configuration. When the Save Configuration page appears, you
must click Save.
