What is BS EN 50083‑2‑4 - Cable networks for television signals, sound signals and interactive services about?
BS EN 50083 is a series on cable networks for television signals, sound signals and interactive services. It is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. BS EN 50083‑2‑4 provides requirements for passive filters intended to reduce RF interference from mobile Base Stations (BS) and User Equipment (UE) to receiving equipment and master antenna cable distribution systems of broadcast DVB-T and DVB-T2 signals in the VHF and UHF bands. While primarily intended to be used with VHF/UHF DVB-T and DVB-T2 receivers and signal distribution systems, filters can also be useful for mitigation of interference to VHF FM or DAB radio.
The signals are typically transmitted in networks by frequency-multiplexing techniques. This includes, for instance:
- Regional and local broadband cable networks
- Extended satellite and terrestrial television distribution systems
- Individual satellite and terrestrial television receiving systems
- All kinds of equipment, systems and installations used in such cable networks, distribution and receiving systems.
Who is BS EN 50083‑2‑4 - Cable networks for television signals, sound signals and interactive services for?
BS EN 50083‑2‑4 on cable networks is useful for:
- Telecommunication equipment manufacturers
- Electrical equipment manufacturers
- Design engineer
- Quality control personnel
- Research and development facilities
Why should you use BS EN 50083‑2‑4 - Cable networks for television signals, sound signals and interactive services?
Networking cables are networking hardware used to connect one network device to other network devices or to connect two or more computers to share printers, scanners etc. BS EN 50083‑2‑4 deals 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.
BS EN 50083‑2‑4 introduces the requirements for Interference Mitigation Filters with stopbands for the 700 MHz and 800 MHz bands. Interference Mitigation Filters are for use in individual and MATV antenna installations for the reception of DTT signals when the 700 MHz bands will be used by telecommunication services in addition to the 800 MHz band. These requirements extend those of CLC/TS 50083-2-3 for mitigation filters for LTE services operating in the 800 MHz band only and ETSI EN 303 354 V.1.1.1 (2017-03), that deals with “Amplifiers and active antennas for TV broadcast reception in domestic premises; Harmonized standard covering the essential requirements of article 3.2 of Directive 2014/53/EU”.
The ETSI document is mainly applicable to new equipment available on the market, while BS EN 50083‑2‑4 has the purpose to allow the existing individual and MATV antenna installations as well as amplifiers designed for the full spectrum of band 4 and 5 for the reception of DTT signals to avoid or mitigate the interference due to the new telecommunication services when the 700 MHz band is added to the 800 MHz band already used. Using BS EN 50083‑2‑4 you can understand requirements for passive filters intended to reduce RF interference from mobile Base Stations (BS) and User Equipment (UE) to receiving equipment and master antenna cable distribution systems of broadcast DVB-T and DVB-T2 signals in the VHF and UHF bands.
