Standards of EN 50083 series deal with cable networks for television signals, sound signals and interactive services including equipment, systems and installationsfor headend-reception, processing and distribution of television and sound signals and their associated data signals, andfor processing, interfacing and transmitting all kinds of signals for interactive services using all applicable transmission media.All kinds of networks likeCATV-networksMATV-networks and SMATV-networksindividual receiving networksand all kinds of equipment, systems and installations installed in such networks, are within this scope.The extent of these standardisation work is from the antennas, special signal source inputs to the headend or other interface points to the network up to the system outlet or the terminal input, where no system outlet exists.The standardisation of any user terminals (i.e. tuners, receivers, decoders, multimedia terminals etc.) as well as of any coaxial and optical cables and accessories therefor is excluded.
