Abstract: This paper <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> presents a design and streaming architecture model of a Universal Multimedia Access (UMA) viewer <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> capable of handling multimedia presentations in an MPEG-21 environment. To demonstrate the above, a software testbed has been implemented based on MPEG-21 ISO standard for validating UMA viewer requirements by having full control of the presentation platform. In this testbed, communication between a client and a server is initiated for exchange of media content considering various factors like terminal capabilities and network conditions. The proposed streaming scheme shows the efficient exchange of MPEG-4 media, which provides a broad platform for presentation of media content over a variety of devices, in a UMA framework.
