1.1 General
Standards and deliverables of EN 50083 (all parts) and EN 60728 (all parts) deal with cable networks including equipment and associated methods of measurement
for headend reception, processing and distribution of television and sound signals
and for processing, interfacing and transmitting all kinds of data signals for interactive
services using all applicable transmission media. These signals are typically transmitted
in networks by frequency-multiplexing techniques.
For instance, this includes
-
a) regional and local broadband cable networks,
-
b) extended satellite and terrestrial television distribution systems,
-
c) individual satellite and terrestrial television receiving systems,
and all kinds of equipment, systems and installations used in such cable networks,
distribution and receiving systems.
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 of the customer premises equipment.
The standardization work will consider coexistence with users of the RF spectrum in
wired and wireless transmission systems.
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.
