IEC 62574:2011 音频,视频和多媒体系统.多通道音频的一般信道分配

This International Standard specifies the general channel assignment for multichannel audio formats. The general channel assignment as a channel mapping and labeling provides the unified usage of channel assignments for source devices@ digital audio interfaces and sink devices. This standard excludes the specification of the exact position of each loudspeaker. It is aimed at consumer applications@ but is not targeted for theatrical environments. Up to 32 labels for loudspeaker positions are specified@ which can be used for all current multichannel formats.

ITU-R REPORT BS.2144-2009 在低于30兆赫频率下运作的数字调幅广播(DRM)的规划参数和覆盖范围

Countries around the world are in the process of migrating from analogue to digital broadcasting techniques for both television and radio. This Report looks at sound broadcasting in the bands below 30 MHz. It briefly examines the underlying reasons for the migration and looks at the technologies involved. Its focus is the DRM system as developed for use in the LF, MF and HF bands. The Report is intended to: 1) Explain why and how a broadcaster might go digital. 2) Be a reference technical document for DRM planning. 3) Provide new information based on the practical experience in DRM. 英：planning parameters;coverage;digital radio mondiale;broadcasting;frequency

ITU-R QUESTION 282/4-2009 1-3 GHz频率范围内与广播卫星业务(声音)介绍相关的频率共享问题

The ITU Radiocommunication Assembly considering a) that frequency allocations to the broadcasting-satellite service (BSS) (sound) and complementary terrestrial broadcasting exist in bands near 1.5, 2.3 and 2.6 GHz for digital sound broadcasting to portable and vehicular receivers; b) that all three of the allocated bands contain allocations to certain terrestrial services, and that the 2.6 GHz band also contains an allocation to the fixed-satellite service (space-to-Earth) in Regions 2 and 3 and to the mobile-satellite service (Earth-to-space); c) that it is necessary to ensure that the introduction of the BSS (sound) and complementary terrestrial broadcasting proceeds in a flexible and equitable manner; d) that this objective is addressed by Resolution 528 (Rev.WRC-03), which calls for the convening of a competent conference for the planning of the broadcasting-satellite service (sound) in the allocated bands, and the development of procedures for the coordinated use of complementary terrestrial broadcasting; e) that Resolution 528 (Rev.WRC-03) also specifies a coordination procedure to be used for the introduction of digital sound broadcasting-satellite systems in the interim period prior to the conference, and that the calculation methods and interference criteria to be employed in the application of this procedure be based upon relevant ITU-R Recommendations; f) that Resolution 528 (Rev.WRC-03) calls upon the conference cited in considering d),above, to review the criteria for sharing with other services.

BS EN 60728-1:2008 电视信号,声音信号和交互式设备用电缆网络.正向传输路径的系统性能

This part of IEC 60728 is applicable to any cable network (including individual receiving systems) having in the forward path a coaxial cable output and primarily intended for television and sound signals operating between about 30 MHz and 3 000 MHz. This standard specifies the basic methods of measurement of the operational characteristics of cable network having coaxial cable outputs in order to assess the performance of these systems and their performance limits. All requirements refer to the performance limits, which shall be obtained between the input(s) to the headend or headends and 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 at the subscriber’s end of the subscriber’s feeder. Also the requirements which are obtained between the input(s) to the headend or headends and any home network interface (HNI) are given. NOTE 1 Methods of measurement described in this standard are considered as basic. However, any equivalent method that ensures at least the same accuracy may be used. NOTE 2 If the system operator wishes to subdivide the system into a number of parts or wishes to use different transmission media (for example, coaxial cabling, balanced cabling, optical cabling), the accumulation of degradations should not exceed the figures given in this standard. NOTE 3 System performance requirements of return paths as well as specific methods of measurement for the use of the return paths in cable networks are described in IEC 60728-10. Clause 5 defines the system performance limits which will, with an unimpaired input, (headend input signal), produce picture and sound signals (at system outlets) where the impairment to any single parameter will be not worse, in normal operating conditions for any analogue channel, than Grade four on the five-grade impairment scale contained in ITU-BT 500-10. For digitally modulated signals, the quality requirement is a quasi-error-free (QEF) reception. Appropriate performance requirements for the signals at the receiving antennas site are given in Clause 6 in order to provide at the input of the headend of the cable network both analogue and digital television signals with suitable quality. Clause 7 is applicable to home networks (including those of individual receiving systems) using coaxial cables, balanced cables or optical cables and primarily intended for television signals, sound signals and interactive services, operating between about 30 MHz and 3 000 MHz. This clause, considering the basic operational characteristics of a home network, specifies the requirements which shall be obtained at the home network interface (HNI) taking into account the performance requirements given at the system outlet or at the terminal input.
