Coaxial cable and optical fibre systems for the RF distribution of digital television, radio and in-house analog television signals in single and multiple dwelling installations
|Publication Date:||13 May 2016|
This Standard specifies requirements and gives guidelines for the design, installation, electrical safety aspects, working performance and final commissioning and ongoing maintenance of a range of radio frequency (RF) distribution systems using passive and active components that will enable the high quality distribution of off-air and in-house television and radio signals in single and multiple unit dwellings (and where required, in other premises such as electrical goods retail stores, offices, etc.).
The end result of compliant systems and components is to make available RF-based broadcast and, if required, in-house signals carried by coaxial cable or by a combination of coaxial cable and fibre optic cable, to one or several outlets in a user's dwelling(s) and then onto a user's receiver where a tuner may reliably select and decode the desired signal with an adequate robustness by maintaining minimum distortion and interference of the received or input signals.
NOTE: As an important part of this Standard, the recommended signal levels and signal quality at the system outlets (e.g. wallplates) are given in Tables 9.2 (levels), 9.3 (level ratios) and 9.4 (C/N, MER and BER).
This Standard is relevant to systems capable of accommodating the distribution of RF signals depending on service requirements that may include interactive return path, over a frequency range that may cover from 5 MHz to 2150 MHz, including any required d.c. or low frequency power or signalling paths. This Standard covers distribution systems that typically carry, as a minimum, the local digital television free-to-air (FTA) terrestrially broadcast services (see Note below), through to extensive systems that combine terrestrial and satellite IF (single or multiple) or satellite derived distribution. There may also be separately distributed subscription television services.
NOTE: For example, 'FreeView' provides free-to-air digital television and radio in New Zealand.
This Standard provides specifications for a range of passive and active devices including coaxial cable and connectors. The specification compliance of individual components performance and the interaction between them is seen as an essential primary requirement to allow a system design that has a predictable level and quality outcomes.
This Standard provides examples of system topology and although applying limitations, this Standard is not intended to restrict other potentially compliant system topologies.
In addition to a television receiver's RF input, the separate requirement of an interactive-capable connection for a receiver via a separate IP ethernet connection is not covered in this Standard. This Standard does not cover the interfacing and distribution of telephony, IP or other data services within communication systems.
NOTE: The scope is illustrated in Figure 1.1.
