Simulation platform for multimedia broadcast over DVB-SH

In this paper, we want to present a simulation platform for multimedia broadcast over DVB-SH. The platform has been designed and implemented within the context of the ESA study on "Scalable Video Coding Applications and Technologies for mobile satellite based hybrid networks". Its main features are realistic modeling of the multimedia encoding/decoding procedures done at the broadcasting headend and the mobile terminals, a detailed simulation of the DVB-SH link layer, and a representative emulation of the DVB-SH physical layer. With the help of this platform, important use cases for future DVB-SH systems, such as support of heterogeneous devices, graceful degradation of application quality across the coverage area, efficient statistical multiplexing of different services, etc. can be investigated in a straightforward and conclusive manner.
