21、nization for standardization comprising all national electrotechnical committees (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 activit

22、ies, 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

23、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

24、 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

25、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 regi

26、onal 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 wi

27、th 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 62330 has been prepared by T

28、echnical Area 6: Higher data rate storage media and equipment of IEC technical committee 100: Audio, video and multimedia systems and equipment. This bilingual version (2012-12) corresponds to the monolingual English version, published in 2003-05. It was submitted to the national committees for voti

29、ng under the Fast Track Procedure as the following documents: CDV Report on voting 100/506/FCDV 100/605/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon.

30、 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.

31、EC:2003 IEC 62330-3 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 3: Data stream format Part 1 describes the VTR specificatio

32、ns 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 format for 1080i and 720p systems. This part 3 describes the specific

33、ations for transmission of HD-D5 compressed video and audio data stream over 360 Mb/s serial digital interface. 62330-3 IEC:2003 5 HELICAL-SCAN DIGITAL VIDEO CASSETTE RECORDING SYSTEM USING 12,65 mm (0,5 in) MAGNETIC TAPE FORMAT HD-D5 Part 3: Data stream format 1 Scope This part of IEC 62330 defines

34、 the data stream used for synchronous transmission of HD-D5 compressed video and audio data over 360 Mb/s serial digital interface (SDI) for the 525/60 system as defined in SMPTE 259M. This practice does not define data stream structure applicable for transmission over the serial data transport inte

DIF blocks in one field (1 080i), or one frame (720p) of video are numbered from 0 through 5 759. Likewise, DIF slices are

39、numbered from 0 through 479. 6 62330-3 IEC:2003 The relationship between DIF block number (BN) and DIF slice number (SN) within the video field or frame is as shown below: SN = int (BN / 12) where BN = 0 to 5 759 DIF Slice structure is shown in Figure 2.

One 1 080i field or one 72

41、0p frame of 5 760 DIF blocks, containing 489 600 words, are mapped into a rectangular area of 1 920 word columns (from sample number 0 to 1 919 horizontally) by 255 word rows (from line number 9 to 263 in the first field or from line number 271 to 525 in the second field vertically) on SDI. In the c

42、ase of 1 080i, DIF blocks of the 1st field compressed video data shall be mapped into the first field of SDI and DIF Blocks of the second field compressed video data shall be mapped into the second field of SDI respectively. One field contains 480 slice cells. One slice cell is composed of 4 word co

43、lumns by 255 word rows. The slice cell structure over SDI is shown in Figure 3. Each DIF slice (see Figure 2) is allocated into each slice cell according to the following expression: CN = (SN 4) mod 480 + int (SN / 120) where SN: DIF slice number CN: Slice cell number Each slice cell is divided into

44、 12 DIF areas. The DIF area, consisting of 85 words, has four different area configurations; i.e. type A through D as shown in Figure 4. Each DIF area is identified by a DIF area number (AN). The DIF block number (BN), DIF area number (AN), and slice cell number (CN) are correlated through the follo

45、wing expressions: CN = int (BN / 12) 4 mod 480 + int (BN / 1 440) AN = BN mod 12 where BN = 0 to 5 759 62330-3 IEC:2003 7 255 words 4 words 1 920 words 0 1 2 3 4 5 6 7 8 - - - - - - - - - - - - - - - - - - - - - - 476 477 478 479 SN SN SN SN SN SN SN SN SN SN SN SN SN 0 120 240 360 1 121 241 361 2 -
