The Composite Media Group has developed cross-platform MPEG-4
standard compliant technologies, with a particular focus
on lightweight portable client playback and on authoring of composite media, both manual and automated.
Automated machine generation of interoperable, exchangeable media content is applicable for on-demand as well
as live solutions and can include adaptive technologies.
The IBM MPEG-4 XMT Editor Tool is a GUI oriented MPEG-4 content
creation tool implemented using the IBM MPEG-4 Toolkit for Java.
Using XMTEdit various forms of media data can be composed and related to one another
in both space and time. The editor is suitable for rapid storyboard approach content creation.

XMTEdit creates an XMT textual format representation of the content being created, XMT is based on XML
and XMTEdit allows this XMT textual format representation to be directly edited. Whether the content is visually
edited and/or edited directly in the XMT tree view, the created content can be saved in the XMT format or exported
to other formats such as the compressed mp4 binary file. The content can also be previewed during its creation from
the preview window.

XMTBatch is a command line program that allows content developers to convert
between various MPEG-4 formats. It's principle function is to convert from the MPEG-4 XMT textual
format to the compressed binary MP4 interchange file format. The tool is however capable of handling many other
format conversions for MPEG-4 files. The following is a list of its format conversion capabilities
- XMT-O -> XMT-A -> mp4
- mp4 -> hinted stream-ready mp4 for RTP/RTSP delivery
- mp4 -> Interleaved file for HTTP playback
- mp4 -> Interleaved Flexible-multiplex file for HTTP playback
- mp4 -> XMT-A
- WMF (Windows Meta File) -> XMT-O -> XMT-A -> mp4
The IBM AVgen MPEG-4 File Generator Tool generates hinted MPEG-4
files suitable for ISMA compliant
devices as well as 3GPP compliant devices. The Tool combines audio and
video media files into a single hinted MPEG-4 file. The tool supports
adding both ISMA/3GPP compliant media and other popular media content into a
hinted MPEG-4 file. The hinted MPEG-4 file is suitable for ISMA/3GPP compliant
servers. Note: adding non ISMA/3GPP compliant media may not be supported by
specific servers and clients which are purely ISMA/3GPP compliant.

As an example of the integration of the authoring core code into another application we have successfully
implemented the functionality of AVgen as a plug-in to Eclipse.
