23、SSION _ HELICAL-SCAN DIGITAL VIDEO CASSETTE RECORDING SYSTEM USING 12,65 mm (0,5 in) MAGNETIC TAPE FORMAT HD-D5 Part 1: VTR specifications FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committe
24、es (IEC National Committees). 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
25、 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 Interna
26、tional 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 sinc
27、e 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 Natio
28、nal 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
29、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
30、 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 62330-1 has been prepared by Technical Area 6: Higher data rate storage media and equipment of IEC technic
31、al committee 100: Audio, video and multimedia systems and equipment. It was submitted to the national committees for voting under the Fast Track Procedure as the following documents: CDV Report on voting 100/504/CDV 100/603/RVC Full information on the voting for the approval of this standard can be
32、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 committee has decided that the contents of this publication will remain unchanged until 2008. At this date, the publication will be reconfirmed; withdr
33、awn; replaced by a revised edition, or amended. 6 62330-1 IEC:2003(E) IEC 62330 consists of the following parts, under the general title Helical-scan digital video cassette recording system using 12,65 mm (0,5 in) magnetic tape Format HD-D5. Part 1: VTR specifications Part 2: Compression format Part
34、 3: Data stream format This part 1 describes the VTR specifications which are tape, magnetization, helical recording, modulation method and basic system data for high definition video compressed data on 29,97 or 59,94 frame rate. Part 2 describes the specifications for encoding process and data form
35、at for 1080i and 720p systems. Part 3 describes the specifications for transmission of HD-D5 compressed video and audio data stream over 360 Mb/s serial digital interface.62330-1 IEC:2003(E) 7 HELICAL-SCAN DIGITAL VIDEO CASSETTE RECORDING SYSTEM USING 12,65 mm (0,5 in) MAGNETIC TAPE FORMAT HD-D5 Par
36、t 1: VTR specifications 1 Scope This part of IEC 62330 specifies the content, format, and recording method of the data blocks containing HD compressed video data defined in part 2, audio, and associated data which form the helical records on 12,65 mm (0,5 in) tape in cassettes as specified in IEC 61
37、835. In addition, this standard specifies the content, format, and recording method of the longitudinal record containing tracking information for the scanning head associated with the helical records, and also the longitudinal cue audio, and time and control code. One video channel of HD compressed
38、 video data and four independent audio channels are recorded in the digital format. Each of these channels is designed to be capable of independent editing. The HD compressed video data are derived from the following HD video signal: 1080 line / 59,94 Hz field frequency interlace system 720 line / 5
39、9,94 Hz frame frequency progressive system Figure 1 and Figure 2 show block diagrams of the processes involved in the recorder. 8 62330-1 IEC:2003(E) ANALOG/ DIGITAL INTERFACE INTRA- FIELD SHUFFLE BLOCK SHUFFLE AUDIO(ANALOG) (DIGITAL AES/EBU) VIDEO OUTER ECC ENCODER COMPRESSED HD DIGITAL DATA HELICA
