Cable networks for television
signals, sound signals and
interactive services —
Part 10-1: Guidelines for the implementation of
return paths in cable networks
1.1 General
Standards of the EN 50083 and EN 60728 series deal with cable networks including equipment and
associated methods of measurement for headend reception, processing and distribution of television
signals, 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.
This includes
? CATV-networks;
? MATV-networks and SMATV-networks;
? individual receiving networks;
and all kinds of equipment, systems and installations installed in such networks.
The extent of this standardization work is from the antennas and/or special signal source inputs to
the headend or other interface points to the network up to the terminal input.
The standardization of any user terminals (i.e., tuners, receivers, decoders, multimedia terminals,
etc.) as well as of any coaxial, balanced and optical cables and accessories thereof is excluded.
