SUMMARYDVB-SH introduces into the portfolio of standards for broadcasters, a hybrid system that provides TV services to handheld devices by means of satellite transmission coverage, complemented by terrestrial components for locations like dense urban areas, not reachable by the satellite signal.Among the articles devoted to DVB-SH in this special issue of the International Journal of Satellite Communications and Networking, this article reports in particular on the researches performed on the Complementary Ground Component of the DVB-SH hybrid transmission system.The article discusses the key technology elements used in the SH terrestrial transmission, provides an extensive range of performance results based on laboratory measurements, reports on the field trials performed in South-West of France, and concludes with a DVB-SH frequency planning exercise performed over a fictitious 3G network in the German city of Hannover.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
