The object of the IEC is to promote,international co-operation on all questions concerning standardization in the electrical and electronic fields. To,this end and in addition to other activities, the IEC publishes International Standards. Their preparation is,entrusted to technical committees; any IEC National Committee interested in 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. The IEC collaborates closely with the International Organization,for Standardization (ISO) in accordance with conditions determined by agreement between the two,organizations.,2) The formal decisions or agreements of the 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 National Committees.,3) The documents produced have the form of recommendations for international use and are published in the form,of standards, technical specifications, technical reports or guides and they are accepted by the National,Committees in that sense.,4) In order to promote international unification, IEC National Committees undertake to apply IEC International,Standards transparently to the maximum extent possible in their national and regional standards. Any,divergence between the IEC Standard and the corresponding national or regional standard shall be clearly,indicated in the latter.,5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any,equipment declared to be in conformity with one of its standards.,6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject,of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.,International Standard IEC 60958-4 has been prepared by IEC technical committee 100: Audio,video and multimedia systems and equipment.,This second edition of IEC 60958-4 cancels and replaces the first edition published in 1999 and,constitutes a technical revision.,The text of this standard is based on the following documents:,FDIS Report on voting,100/643/FDIS 100/669/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 drafted in accordance with the ISO/IEC Directives, Part 2.,The main changes with respect to the previous edition (1999) are listed below.,. The scope specifies the professional application of IEC 60958-1 (generalities have been,removed to an introduction).,. A clause on terms and definitions has been added.,. In Table 1, expanded channel status assignments have been added and channel status,definitions expanded to accommodate extended sampling frequencies, indication of,alignment level and multi-channel options.,– 2 –,. Figure 1 and associated text has been revised to be more generalized. Three notes on cable,performance factors have been added.,. The impedance specification is now dependent on maximum frame rate.,. The common-mode balance specification is now dependent on maximum frame rate,. The impedance specification is now dependent on maximum frame rate.,IEC 60958 consists of the following parts under the generic title Digital audio interface:,Part 1: General,Part 3: Consumer applications,Part 4: Professional applications,The committee has dec……
