What is BS EN 50083-9 - Interfaces for CATV/SMATV headends and similar professional equipment about?
BS EN 50083-9 is an international standard that discusses cable networks for television signals, sound signals, and interactive services.
BS EN 50083-9 describes physical interfaces for the interconnection of signal processing devices for professional CATV/SMATV headend equipment or for similar systems, such as in uplink stations.
BS EN 50083-9 specifies the transfer of DVB/MPEG-2 data signals in the standardized transport layer format between devices of different signal processing functions.
Note 1: The extent of this standardization 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.
Note 2: The standardization of any user terminals (i.e., tuners, receivers, decoders, multimedia terminals etc.) as well as any coaxial and optical cables and accessories are excluded.
Note 3: RF interfaces and interfaces to telecom networks are not covered in BS EN 50083-9.
Who is BS EN 50083-9- Interfaces for CATV/SMATV headends and similar professional equipment for?
BS EN 50083-9 on interfaces for CATV/SMATV headends and similar professional equipment is relevant to:
- Manufacturers and suppliers of interfaces for CATV/SMATV headends and similar professional equipment
- Manufacturers of Satellite Master Antenna Television system (SMATV)
- Broadcasters and broadcast engineers
- Cable distribution systems personnel
- Quality control personnel
- Product development/innovation teams
Why should you use BS EN 50083-9- Interfaces for CATV/SMATV headends and similar professional equipment?
The headend is equipment that is connected between receiving antennas or other signal sources and the remainder of the cable distribution system to process the signals to be distributed.
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
- For processing, interfacing, and transmitting all kinds of signals for interactive services using all applicable transmission media
BS EN 50083-9 covers all kinds of networks like CATV-networks, MATV-networks, SMATV-networks, individual receiving networks, and all kinds of equipment, systems, and installations installed in such networks.
BS EN 50083-9 specifies the serial or parallel interfaces to the bitrates and transmission formats of the public Plesiochronic Digital Hierarchy (PDH) networks, for connections to telecom networks.
BS EN 50083-9 specifies three interfaces and two serial transmission media which are as follows:
- SPI (Synchronous Parallel Interface)
- SSI-C (Synchronous Serial Interface on coaxial cable)
- SSI-O (Synchronous Serial Interface on optical fibre)
- ASI-C (Asynchronous Serial Interface on coaxial cable)
- ASI-O (Asynchronous Serial Interface on optical fibre)
Each of these interfaces features a BER such that FEC is not required for reliable data transport.
BS EN 50083-9 specifies the interfaces and defines physical connections between various pieces of equipment. It provides a detailed specification of the SSI, and ASI as well as guidelines for its implementation. It is an informative specification that provides you with implementation guidelines and deriving clocks from the MPEG-2 packets for ASI. It also sets guidelines for the implementation and usage of ASI.
BS EN 50083-9 addresses the detailed specification of cable networks for television signals, sound signals, and interactive services. It clarifies all your queries related to interfaces of CATV/SMATV headends and similar professional equipment which can help you to expand your business globally.
Overall, BS EN 50083-9 is useful as it provides guidance on the interfaces for CATV/SMATV headends and similar professional equipment for DVB/MPEG-2 transport streams which can be beneficial for your business.
