25、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 t
26、o 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
27、 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 condi
28、tions 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 Nati
29、onal Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the wa
30、y in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC
31、 Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. I
32、EC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of it
33、s technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any oth
34、er IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the
35、 subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62634 has been prepared by technical area 1: Terminals for audio, video and data services and content, of IEC technical committee 100: Audio, video and multimedia sy
36、stems and equipment. International Standard IEC 62634 cancels and replaces IEC 60315-9, published in 1996, and constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60315-9: use of state-of-the-art measuring methods based on todays RD

38、ategories. 62634 IEC:2011 5 The text of this standard is based on the following documents: FDIS Report on voting 100/1813/FDIS 100/1850/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been dr
39、afted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publi
40、cation will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 62634 IEC:2011 INTRODUCTION This International Standard gives commonly agreed measuring methods to complement the RDS standard IEC 62106 (2009) and the RBDS standard (NRSC-4-A) in the USA. The RDS measuring methods p
41、resented here are directed at all manufacturers of RDS receiver products, and in particular tuner modules with embedded RDS functionality, including TMC (see ISO 14819 series of standards). 62634 IEC:2011 7 RADIO DATA SYSTEM (RDS) RECEIVER PRODUCTS AND CHARACTERISTICS METHODS OF MEASUREMENT 1 Scope
42、This International Standard describes how to measure minimum RDS receiver performance requirements which concern three RDS receiver product categories. However, it should be noted that there are also RDS receiver products on the market that significantly out-perform the minimum RDS receiver performa
43、nce requirements quoted. Methods and algorithms to achieve automatic programme service-following by means of AF lists are, however, very customer- and manufacturer-specific, and are therefore not covered in this standard. 2 Normative references The following referenced documents are indispensable fo
