A QOS-DRIVEN UMA viewer in MPEG-21 framework

This paper
¹
presents a design and streaming architecture model of a Universal Multimedia Access (UMA) viewer
²
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.
