Abstract

In order to enable transparent and augmented use of multimedia content across a wide range of networks and devices, content adaptation is an important issue within multimedia frameworks. In this paper, we present a prototype application that receives digital video broadcast (DVB) TV streams on a PC, transcodes the streams on the fly according to the individual user requirements and packs the adapted content together with available metadata into a standard compliant MPEG-21 digital item (DI). In this form, the framework enables the live universal multimedia access (UMA) scenario where the DVB content can be transparently accessed by clients such as PCs and PDAs, anytime and anywhere
