BS EN 60728-1-2:2009 电视信号、声音信号和交互式设备用电缆网络.运行系统出口信号传输的性能要求

This part of IEC 60728 provides the minimum performance requirements to be fulfilled in operation at the system outlet or terminal input and describes the summation criteria for the impairments present in the received signals and those produced by the CATV/MATV/SMATV cable network, including individual receiving systems. NOTE 1 When a change of signal format is made at the headend, the summation of the impairments does not apply (see also Clause 57H 7). In a building divided into apartment blocks, the signals received by the antennas are distributed by the MATV/SMATV cable network up to the home network interface (HNI); the television signals are then distributed (inside the home) by home networks (HN) of various types up to the system outlet or terminal input. The cable network can support two way operation, from the system outlet (or terminal input) towards the headend. The home network can use coaxial cables, balanced pair cables, fibre optic cables (glass or plastic) and also wireless links inside a room (or a small number of adjacent rooms) to replace wired cords. This part of IEC 60728 is applicable to cable networks intended for television signals, sound signals and interactive services operating between about 5 MHz and 3 000 MHz. The frequency range is extended to 6 000 MHz for home 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 GHz to 6 GHz frequency band. 64H64H64H58HFigure 1 shows the main sections of a general CATV/MATV/SMATV system, indicating the parts of the IEC 60728-1 series documents where the relevant performance requirements are indicated. • The requirements for the signals received at the headend are given in Clause 6 of IEC 60728-1. • The requirements for the CATV/MATV/SMATV cable network, assuming an unimpaired input signal at the input of the headend, up to the system outlet are given in IEC 60728-1, Clause 5. • The requirements for the CATV/MATV/SMATV cable network up to the home network interface (HNI) are given in IEC 60728-1, Clause 7, assuming an unimpaired input signal at the input of the headend. • The specific requirements from HNI to the system outlet or terminal input are given in IEC 60728-1-1, Clause 5, assuming an unimpaired input signal at the HNI. • The requirements at the system outlet in operation are given in Clause 7 of this standard. The expression “in operation” means that the received signals, with their impairments, are applied to the headend input of the CATV/MATV/SMATV cable network. The requirements at the system outlet “in operation” are derived, therefore, by summing the impairments of the various cascaded parts of the system and of the input signal. When a change of signal format from analogue to analogue (e.g. from FM to AM-VSB) or from digital to digital (e.g. from QPSK to QAM) or from digital to analogue (e.g. from DVB-S/S2 to AM-VSB or DVB-T to AM-VSB) is made at the headend, the summation of the impairments that produce a relaxation of requirements at system outlet does not apply. Such a case will be the equivalence of unimpaired signals applied at the headend input. Therefore the requirements at system outlet given in IEC 60728-1 apply. This standard also provides references for the basic methods of measurement of the operational characteristics of the downstream cable network in order to assess its performance. All requirements refer to the performance limits to be achieved in operation at any system outlet when terminated in a resistance equal to the nominal load impedance of the system, unless otherwise specified. Where system outlets are not used, the above applies to the terminal input.

The ITU Radiocommunication Assembly considering a) that preservation of important sound programme recordings is essential and it forms an integral part of the activity of a broadcast organization; b) that a compromise may generally need to be found between archived sound quality, volume of the archive, speed of access to archived programmes, and number of work stations that can simultaneously access the archive; c) that recourse to digital audio servers, using Information Technology (IT) equipment, is currently a viable approach to an efficient archive of sound programmes; d) that the storage medium plays an important role in determining the life span of archive material; e) that the archival method may require audio coding parameters different from those required for the studio and for the emission of high-quality broadcast signals; f) that impairment to audio signals is minimized and the implementation of transcoding equipment is simplified if there is a simple relationship between the digital audio coding standards used for production, transmission, emission and archiving; g) that Recommendations on digital audio coding and bit-rate reduction standards are already available both for the studio and for the broadcast environment; h) that the quality of legacy recordings could be improved by using restoration techniques, which, with advancement in technologies, may undergo improvements, and this may require the preservation of the original recordin

IEC 60728-13:2010 电视信号、声音信号和交互式服务用电缆网络.第13部分:广播信号传输用光学系统

This part of IEC 60728 is applicable to optical transmission system for broadcast signal transmission that consists of a head-end equipment@ optical transmission lines@ in-house wirings and a system outlet. The system is primarily intended for television and sound signals using analogue and/or digital transmission technology. This standard specifies the basic system parameters and methods of measurement for optical distribution system having a system outlet in order to assess the system performance and its performance limits. The purpose of this part of IEC 60728 is to describe the system specification of FTTH (fibre to the home) network for broadcast signal transmission. This standard is also applicable to the broadcast signal transmission using telecommunication network if it satisfies the optical portion of this standard. This standard describes RF transmission for broadcast and narrowcast (limited area distribution of broadcast) signals over FTTH@ and introduces xPON system as a physical layer media. The detailed description of physical layer is out of the scope of this standard. The scope is limited to RF signal transmission over FTTH@ thus@ it does not include IP transport technologies@ such as IP Multicast and associate protocols. Some interference descriptions between telecommunication system and broadcast system addressed in Clause 7 and Annex D should be referred to for detailed explanations. Annex A describes actual service systems with design consideration based on this standard. Annex B gives an overview of the optical transmission systems applicable for broadcast signal transmission.
