25、ide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of 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 act
26、ivities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subjec
27、t dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions dete
28、rmined by agreement between the two organizations. 2) The formal decisions or agreements of 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 IEC National Commi
29、ttees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which
30、 they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publicati
31、on and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that
32、 they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any natu
33、re whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced
34、 publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. Internation
35、al Standard IEC 62071-3 has been prepared by technical area 6: Higher data rate storage media, data structures and equipment of IEC technical committee 100: Audio, video and multimedia systems and equipment. This bilingual version (2013-07) corresponds to the monolingual English version, published i
36、n 2005-10. The text of this standard is based on the following documents: CDV Report on voting 100/902/CDV 100/986/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
37、voted upon. 4 62071-3 IEC:2005 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. IEC 62071 consists of the following parts, under the general title Helical-scan compressed digital video cassette system using 6,35 mm magnetic tape Format D-7: Part 1: VTR specificati
38、ons Part 2: Compression format Part 3: Data stream format This part 3 describes the specifications for transmission of DV-based compressed video and audio data stream over 270Mb/s and 360 Mb/s serial digital interface. Part 1 describes the VTR specifications which are tape, magnetization, helical re
39、cording, modulation method and basic system data for video compressed data. Part 2 describes the specifications for encoding process and data format for 525i and 625i systems. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indi
40、cated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. 62071-3 IEC:2005 5 HELICAL-SCAN COMPRESSED DIGITAL VIDEO CASSETTE SYSTEM USING 6,35 mm MAG
41、NETIC TAPE FORMAT D-7 Part 3: Data stream format 1 Scope This part of IEC 62071 defines the format of the data stream for the synchronous exchange of DV-based audio, data, and compressed video (whose data structure is defined in SMPTE 314M) over the interface defined in SMPTE 305M. It covers the tra
42、nsmission of audio, subcode data and compressed video packets associated with DV-based 25 and 50 Mb/s data structures including faster-than-real-time transmission for 525/60 SDTI and 625/50 SDTI systems. This standard does not include the data stream of a DV-compressed structure as defined in SMPTE
43、322M. Space within SMPTE 305M not used by a data stream conforming to this standard may be used for the transmission of data other than those representing DV-based audio, data and compressed video. In this standard, the 60 Hz system refers to the field frequency 59,94 Hz system and the 50 Hz system
44、refers to the field frequency 50,0 Hz system. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any a
45、mendments) applies.

48、05M. When the SDTI interface is transporting a data stream conforming to this standard, the block type word within the SDTI header packet shall have the value 173h for transported data contained in fixed-size blocks when ECC (error correction code) is used and the value 233h when ECC is not used. 4.
49、2 Payload The payload is composed of consecutive fixed-size blocks (see Figure 1). The SDTI data type word shall identify the data type of this payload with the value 221h. 5 Stream block format The stream block format is shown in Figure 1. The length of each stream block is 170 words, including a secondary header, two DIF (digital interface) block IDs, two DIF block data (of s
