Abstract: Trends in multimedia consumer electronics, digital video and audio, aim to reach users through low-cost mobile devices connected to data broadcasting networks with limited bandwidth. An emergent broadcasting network is the digital audio broadcasting network (DAB) which provides CD quality audio transmission together with robustness and efficiency techniques to allow good quality reception in motion conditions. This paper focuses on the system-level evaluation of different architectural options to allow low bandwidth digital video reception over DAB, based on video compression techniques. Profiling and design space exploration techniques are applied over the ASP MPEG-4 decoder in order to find out the best HW/SW partition given the application and platform constraints. An innovative SystemC-based system-level design tool, called CASSE, is being used for modelling, exploration and evaluation of different ASP MPEG-4 decoder HW/SW partitions. System-level trade offs and quantitative data derived from this analysis are also presented in this work.
