More and more multimedia devices such as televisions, stereo systems, digital video recorders, but also cell phones can now be networked with one another. However, the previous applications are often limited to the pure data exchange or refer only to certain manufacturers. The employees at the chair for computer graphics at Saarland University have therefore developed the so-called "Network-Integrated Multimedia Middleware (NMM)", which can support any network and very different operating systems. The scientists will present their system in a lecture on Linux Day 2005 on June 24, 2005 at 11 am. Around 16,000 IT decision-makers, software developers and users are expected to discuss free software, Linux and open source at Linux Day, which will take place from June 22nd to 25th, 2005 in the exhibition and congress center in Karlsruhe.

The software architecture NMM from Saarbr├╝cken-based computer scientists enables all devices in the network to be transparently interconnected. In addition, the control options are also extended to the network. This creates completely new, "virtual" devices: the cell phone becomes a radio receiver and a video can be viewed on three televisions at the same time. The ability to work across platforms is also unique to date. Any network technology and very different operating systems are supported. The software runs on Windows systems, such as the home PC, but also on various Linux and Unix systems such as set-top boxes, cell phones or personal digital assistants (PDAs). NMM is the result of several years of research at the chair for computer graphics at Saarland University. As an open source project, the aim is to create a uniform software interface for Linux and other operating systems.

The possibilities of this software architecture will be explained at the Linux Day 2005 in a lecture and a demonstration. NMM allows all existing devices to be flexibly integrated and controlled centrally, for example to be able to access the TV program in the entire household. Media playback can also be spontaneously shifted from one device to another, for example from the portable MP3 player to the stereo system in the living room. At the same time, different users can be connected to presentations that have already started and thus consume the same content simultaneously on different end devices.

Due to the flexible licensing options, the developed multimedia architecture can be used in open source and research projects as well as commercial products. In the future, professional support will be provided by a spin-off company that specializes in this area.
