The utility of MPEG-7 systems in audio-visual applications with multiple streams

The MPEG-7 standard presents several interesting challenges with regard to manipulating multimedia content descriptions. We discuss two exemplary applications for MPEG-7: personalized TV services and video surveillance. In doing so, we introduce some capabilities into the standard that test the limits of the current models, namely those of multiple streams and those of carouseling and synch-points. We then introduce proposed extensions that facilitate these additional functionalities, and explore their impact upon the models within the standard.
