154 FOREWORD

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

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

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

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

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

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

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

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

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

164 agreement between the two organizations.

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

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

167 interested IEC National Committees.

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

169 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

170 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

171 misinterpretation by any end user.

172 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

173 transparently to the maximum extent possible in their national and regional publications. Any divergence

174 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

175 the latter.

176 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

177 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

178 services carried out by independent certification bodies.

179 6) All users should ensure that they have the latest edition of this publication.

180 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

181 members of its technical committees and IEC National Committees for any personal injury, property damage or

182 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

183 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

184 Publications.

185 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

186 indispensable for the correct application of this publication.

187 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

188 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

189 International Standard IEC 60728-101-1 has been prepared by technical area 5: Cable

190 networks for television signals, sound signals and interactive services, of IEC technical

191 committee 100: Audio, video and multimedia systems and equipment.

215 INTRODUCTION

216 Standards and deliverables of IEC 60728 series deals with cable networks including

217 equipment and associated methods of measurement for headend reception, processing and

218 distribution of television and sound signals and for processing, interfacing and transmitting all

219 kinds of data signals for interactive services using all applicable transmission media. These

220 signals are typically transmitted in networks by frequency-multiplexing techniques.

221 This includes for instance
222 • regional and local broadband cable networks,
223 • extended satellite and terrestrial television distribution systems,
224 • individual satellite and terrestrial television receiving systems,

225 and all kinds of equipment, systems and installations used in such cable networks, distribution

226 and receiving systems.

227 The extent of this standardization work is from the antennas and/or special signal source

228 inputs to the headend or other interface points to the network up to the terminal input of the

229 customer premises equipment.

230 The standardization work will consider coexistence with users of the RF spectrum in wired

231 and wireless transmission systems.

232 The standardization of any user terminals (i.e. tuners, receivers, decoders, multimedia

233 terminals etc.) as well as of any coaxial, balanced and optical cables and accessories thereof

234 is excluded.

235 The reception of television signals inside a building requires an outdoor antenna and a

236 distribution network to convey the signal to the TV receivers.

237 This part of the IEC 60728 deals with the requirements and implementation guidelines for a

238 home network that can be realised with different techniques. The following types of home

239 networks (HN) are possible:
240 • passive coaxial home network;
241 • active coaxial home network;
242 • different home network types.

243 Figure 1 shows typical situations that are possible when considering RF home networks.

244 The RF home network can be realised using coaxial cables, balanced cables, optical cables

245 or radio links.

246 This document considers digital signals only and is based on IEC 60728-101 dealing with

247 system performance of forward paths loaded with digital channels only. For RF cable systems

248 loaded with analogue and digital signals refer to IEC 60728-1-1 ED2.

249 Figures 4 to 9 have been amended to take into account the level requirement for digital

250 signals only.

251 Although the upper frequency range of terrestrial broadcast signals depends on the allocation

252 frequency plan of each region (e.g., in Europe it is reduced to 694 MHz, being the 700 MHz

253 and 800 MHz bands assigned to telecommunication services), the upper frequency range into

254 the cable networks can be maintained to 862 MHz in order to maximise the number of

255 channels to be distributed in the cable networks, assuming that sufficient immunity (screening

256 efficiency) to signals radiated in the 700 MHz and 800 MHz bands is provided.

268
269 1 Scope

270 This part of IEC 60728 provides the requirements and describes the implementation

271 guidelines of RF cabling for two-way home networks; it is applicable to any home network that

272 distributes signals provided by CATV/MATV/SMATV cable networks (including individual

273 receiving systems) having a coaxial cable output. It is also applicable to home networks

274 where some part of the distribution network uses wireless links, for example in place of the

275 receiver cord.

276 This part of IEC 60728 is therefore applicable to RF cabling for two-way home networks with

277 wired cords or wireless links inside a room and primarily intended for television and sound

278 signals operating between about 5 MHz and 3 300 MHz. The frequency range is extended to

279 6 000 MHz for distribution techniques that replace wired cords with a wireless two-way

280 communication inside a room (or a small number of adjacent rooms) that uses the 5 GHz to

281 6 GHz band.

282 In a building divided into apartment blocks, the distribution of the signals inside the home

283 starts from the home network interface (HNI) up to the system outlet or terminal input. The

284 requirements at the system outlet are given in IEC 60728-101, Clause 5 and the requirements

285 at the HNI are given in IEC 60728-101, Clause 7. In Clause 5 of this standard additional

286 requirements are given.
287 This document deals with various possibilities to distribute signals
