We have got a couple of MXM publications in books and journals recently we’d like to share. We do hope they help understanding the MXM and we also highlight some use cases:
- Christian Timmerer, Filippo Chiariglione, Marius Preda, and Victor Rodriguez Doncel, Accelerating Media Business Developments with the MPEG Extensible Middleware, IEEE Multimedia, vol. 17 no. 3, pp. 74-78, July-September 2010. [IEEE-MM]
- Víctor Rodríguez Doncel, Jaime Delgado, Filippo Chiariglione, Marius Preda and Christian Timmerer, Interoperable digital rights management based on the MPEG Extensible Middleware, Multimedia Tools and Applications, April 7, 2010. [Springer] [PDF]
- Christian Timmerer, Filippo Chiariglione, Marius Preda, and Victor Rodriguez Doncel, Accelerating Media Business Developments with the MPEG Extensible Middleware, in: Georgios Tselentis, Alex Galis, Anastasius Gavras, Srdjan Krco, Volkmar Lotz, Elena Simperl, Burkhard Stiller, Theodore Zahariadis (eds.), Towards the Future Internet - Emerging Trends from European Research, IOS Press, pp. 217-226, 2010.

Please provide feedback in the comments section if you like…
We are upgrading our hardware and, thus, this Web site is not available from Fri 19.2., 7pm to Sat 20.2., 11 am. We are sorry for any inconvenience this may cause.
The MXM specifications have been updated to “Study of FCD” level which means that we are going to Final Draft International Standard (FDIS) at the next meeting.
…and APIs available online have been updated too.
Please let us know if you have any comments. It is your last chance before the standards are going to be finally approved by MPEG. Of course, there is room and space for amendments and new editions but that is another story…
We had a poster presentation at the Future Internet Assembly in Stockholm which is provided here in a more general form.
Furthermore, we had a PowerPoint presentation running during the poster sessions which is also provided here:
The MXM session at the 90th MPEG Meeting in Xi’an, China concluded with a couple of very interesting features to be included into the MXM standard:
- MPEG-7 Visual API is now covering both video and image media resources;
- A basic MPEG-4 Audio API has been proposed supporting both encoding and decoding;
- The Generic Metadata API has been revised in order to accommodate modifications within the W3C Media Annotation API;
- The exception handling for C++ has been improved;
- MXM protocol improvements and extensions
- Improvement of the base protocol message;
- Improvement of the IPMP tool protocols;
- Addition of an Event Reporting Collecting Device and corresponding protocols;
We have also received a proposal for including a format identification engine which shall provide means for identifying the coding/transport format of a given bitstream. However, a few open issues needs to be solved before it can be included in the standard and the proponents are encouraged to provide a revised input at the next meeting.
Furthermore, we have produced a couple of so-called 1-pagers (or overview papers) which will appear at MPEG’s Technology Web site soon.
Currently, editors are working on the “Study of …” documents to incorporate the above mentioned additions. These documents have an editing period and we will post here once they are available.
Finally, an MXM presentation entitled Accelerating Media Business Developments has been given at the workshop at Xidian University the day after the 90th MPEG meeting closed.
A preliminary implementation of the LicenseProtocolEngine has been committed to the MXM svn repository. This can be used to perform the client and the server part of the MXM License Protocols defined in 23006-4:
- On the client side, the engine can be used
- to store License templates on a License Provider Device. See org.dmp.chillout.mxm.licenseprotocolengine.StoreLicenseProtocolDispatcher
- to request a License to a License Provider Device. See org.dmp.chillout.mxm.licenseprotocolengine.AccessLicenseProtocolDispatcher
- On the Server side, it can be used to parse the received messages and generate the response.
A very basic example of an MXM-based License Provider Device has also been provided in folder /JAVA/trunk/mxm-apps/chillout-mxm-lpd. After building the project using maven, the generated chillout-mxm-lpd-0.2.0.war file can be deployed under Tomcat. If the server is running, by visiting the URL http://localhost:8080/chillout-mxm-lpd/servlet/AxisServlet (or http://localhost:8080/chillout-mxm-lpd-0.2.0/servlet/AxisServlet depending on your Tomcat configuration) you will see the two services: StoreLicenseRequestProcessor and RequestLicenseProcessor up and running.
To test the client side of the LicenseProtocolEngine, the following test classes can be run as JUnit tests:
If the chillout-mxm-lpd web application is running, the tests will be executed successfully.
Thank you in advance for your feedback.
The MPEG Extensible Middleware (MXM) standard, formally known as ISO/IEC 23006, is currently at Final Committee Draft (FCD) stage. It comprises four parts, all are publicly available:
* … this part was previously known as ISO/IEC 29116-2 (Part 2 of the Supplemental Media Technologies) and has been recently moved to MXM.
Furthermore, the MXM license can be found here which basically adopts the BSD license as posted previously. Other publicly available documents - such as requirements, context & objectives, etc. - can be found under the “General” section elsewhere.
According to SC29, the FCD ballot is open until 9th of January 2010 but in case you have any questions or suggestions, please let us know by commenting here or joining the Ad-hoc Group (AhG). The next MPEG meeting is approaching and we expect that any MXM-related inputs will find their way into so-called “Study of …” documents of the respective standards. That is, intermediate versions of the individual parts that may form the basis when drafting the Final Draft International Standard (FDIS) which will probably happen in January 2010.
