18、ropean Standard was prepared by Technical Committee CENELEC TC 203, Electronic entertainment and educational systems for household and similar use. The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50049-1 on 1997-07-01. This European Standard supersedes EN 500

19、49-1:1989, which was approved by CENELEC on 1988-09-13. Since this date the evolution of services is such that several amendments were approved. Also the application implies the introduction in the European Standard of some general rules independent of the interconnection architecture. Due to this a

20、 new edition has become necessary. Significant technical differences are: a) addition: contents of amendments A1, A2, A3, A4 b) deletion: connector characteristics which are contained in IEC 60807-9. c) addition: clause 6 Essential/optional signal types for various applications. The following dates

21、were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 1998-06-01 latest date by which national standards conflicting with the EN have to be withdrawn (dow) 1998-06-01 Foreword to amendment A1 This amen

22、dment was prepared by the former Technical Committee CENELEC TC 203, Electronic entertainment and educational systems for household and similar use (in July 1998 TC 203 has become part of TC 206, Consumer equipment for entertainment and information and related sub-systems). The text of the draft (pr

23、AA) was submitted to the formal vote and was approved by CENELEC as amendment A1 to EN 50049-1:1997 on 1998-08-01. The following dates were fixed: latest date by which the amendment has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 1999-

24、08-01 latest date by which national standards conflicting with the amendment have to be withdrawn (dow) 1999-08-01Page 3 EN 50049-1:1997 BSI 02-2000 1 Introduction 1.1 Object This standard defines the interconnection characteristics of peritelevision devices, both between themselves and with televis

25、ion receivers (monochrome or colour). The interconnections covered by this standard are at baseband (video and audio) or digital signals. For the purpose of defining conformance, this standard specifies the types and related groups of signals, composite video, audio, primary colour and control that

26、shall be present on the connectors. The levels and impedances together with the tolerances on these values are also specified. The manner in which the signals on the connector are processed within the products incorporating the connectors and the presentation of the results of such processing to the

27、 user is outside the scope of this standard. These details depend upon the system involved, e.g. PAL or SECAM and the specification of the product. This standard lays down collectively the electrical matching characteristics (type of signals, voltage and impedance values), dimensional, mechanical an

28、d electrical characteristics of the connectors, type and wiring of interconnection cordsets. Attention is drawn to the fact that the interconnection covered by this standard shall in any circumstances meet the safety requirements specified in EN 60065:1993 and the electromagnetic compatibility requi

29、rements specified in the appropriate publications. 1.2 Field of application This standard applies to the connector socket mounted on various devices that are components of domestic audio-visual systems, and includes the designation of contacts, the type of interchanged signals and the matching value

30、s of voltage and impedance. This standard does not apply to equipment so small that its size is not compatible with the dimensions of the socket. It applies also to the plug fitted to the end of interconnection cordsets. It covers the interconnection cordsets themselves (type of conductors, wiring).

31、 Permanent connection of several pieces of equipment which may be used simultaneously or otherwise is ensured: either by fitting each piece of equipment with a suitable number of connectors; or by a single connector on each piece of equipment linked to a central interconnection and switching device.

32、 The user shall be informed about the possible applications that are provided by a device. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the

33、 publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (includ
