It is identical with IEC 61041-4:1997. The UK participation in its preparatio
5、n was entrusted by Technical Committee EPL/100, Audio,video and multimedia systems and equipment, to Subcommittee EPL/100/2, Recording, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretati
6、on, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. For ease of reference to other parts of BS 743
7、4, this standard has also been designated as BS 7434-4. IEC 61041 consists of the following parts: Part 1: General video (NTSC/PAL) and audio (longitudinal) characteristics; Part 2: Video characteristics chrominance SECAM; Part 3: Audio characteristics for FM recording; Part 4: Calibration tape (NTS
8、C/PAL/SECAM); Part 5: High-band video tape recorders, including those equipped with Y/C video connectors (NTSC/PAL). From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the cha
9、nge over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their corresponding Eu
10、ropean publications. The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards E
11、lectronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages Thi
