Abstract

The broadcast network consisting of DVB-H and IP Datacast enables an efficient transport of multimedia content like for example audio and video files to small battery-powered devices. More precisely, DVB-H specifies the physical layer and IP Datacast complements DVB-H with the higher protocol layers to form a complete end-to-end system. Additionally, IP Datacast supports the usage of a mobile network (e.g. UMTS). A network using a broadcast and a mobile network jointly for data transmission is called a hybrid (broadcast/mobile) network. In this paper an analytical description of such a hybrid network is derived. Based on this model the performance of hybrid networks is discussed.
