Cable networks for television signals sound signals and interactive services -- Part 1-1: RF cabling for two way home networks (IEC 60728-1-1:2014)

Standard provides the requirements and describes the implementation guidelines of RF cabling for two-way home networks. This standard is applicable to any home network that distributes signals provided by CATV/MATV/SMATV cable networks (including individual receiving systems) having a coaxial cable output. This standard also applies to home networks where some part of the distribution network uses wireless links, for example instead of the receiver cord. This part of IEC 60728 is therefore applicable to RF cabling for two-way home networks with wired cords or wireless links inside a room and primarily intended for television and sound signals operating between about 5 MHz and 3 000 MHz. The frequency range is extended to 6 000 MHz for distribution techniques that replace wired cords with a wireless two-way communication inside a room (or a small number of adjacent rooms) that uses the 5

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 1-1: Câblage RF pour réseaux domestiques bidirectionnels (CEI 60728-1-1:2014)

L'IEC 60728-1-1:2014 s'applique aux câblages RF destinés aux réseaux domestiques bidirectionnels utilisant des cordons à fil ou des liaisons sans fil à l'intérieur d'une pièce et essentiellement destinés aux signaux de télévision et de radiodiffusion sonore utilisés approximativement entre 5 MHz et 3 000 MHz. La bande de fréquences est étendue à 6 000 MHz pour des techniques de distribution où les cordons à fil sont remplacés par une communication bidirectionnelle sans fil. Cette deuxième édition annule et remplace la première édition parue en 2010, dont elle constitue une révision technique. Elle inclut les modifications suivante: mise à jour des exigences de qualité de l'Article 5 afin d'inclure les exigences pour les signaux DVB-T2.

Kabelska omrežja za televizijske in zvokovne signale ter interaktivne storitve - 1-1. del: RF-okablenje za dvosmerna domača omrežja (IEC 60728-1-1:2014)

Standard določa zahteve in opisuje izvedbene smernice RF-okablenja za dvosmerna domača omrežja. Ta standard se uporablja za katero koli domače omrežje, ki distribuira signale, ki jih posredujejo kabelska omrežja CATV/MATV/SMATV (vključno s posamičnimi sistemi za sprejem) s koaksialnim kabelskim izhodom. Ta standard se uporablja tudi za domača omrežja, pri katerih del razdelilnega omrežja uporablja brezžične povezave, na primer namesto sprejemnega kabla. Ta del standarda IEC 60728 se torej uporablja za radiofrekvenčne kable za dvosmerna domača omrežja z žičnimi kabli ali brezžičnimi povezavami znotraj sobe ter je namenjen predvsem za televizijske in zvokovne signale s frekvenco med približno 5 MHz in 3000 MHz. Frekvenčni razpon se poveča na 6000 MHz pri distribucijskih tehnikah, ki nadomeščajo žične kable z brezžično dvosmerno komunikacijo znotraj sobe (ali manjšega števila sosednjih sob), ki uporablja pas med 5 GHz in 6 GHz.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
