The combination of the emerging digital video broadcasting-handheld (DVB-H) standard with cellular communication like UMTS produces a hybrid network with enormous potential for mobile multimedia applications. In order to optimize the performance of hybrid networks, the characteristics of different individual networks have to be considered. Our prototypical hybrid network infrastructure employs smart access management for an optimal usage of both broadcast and point-to-point network. Our demonstrator-"night scene live", a multimedia event portal-is an excellent example of an application exploiting the potential of future hybrid networks
