Multicast Transmission Optimization Over Hybrid DVB-SH Systems

Free registration required

Executive Summary

Research interest related to hybrid networks for mobile users has rapidly evolved in order to extend service to all users. In particular, DVB-SH provides an efficient way of carrying multimedia services over hybrid satellite and terrestrial networks for a big diversity of terminals. Also a variety of possible hybrid system architectures can be chosen due to the two different physical layers specified: ODFM and TDM. Although DVB-SH has been designed for broadcast transmission, the authors propose to use it for multicast applications, which is more competitive over satellite systems.
