FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide 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 activities, 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 subject 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 determined 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 Committees.
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 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 Publication 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 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 nature 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 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.
International Standard IEC 61883-3 has been prepared by technical area 4: Digital system
interfaces and protocols, of IEC technical committee 100: Audio, video and multimedia
systems and equipment.
This second edition of IEC 61883-3 cancels and replaces the first edition published in 1998.
This edition contains the following significant technical changes with respect to the previous
edition:
Added specifications of IEEE 1394 packet, CIP header and transmission timing in high speed
transmission.
This bilingual version (2014-04) corresponds to the monolingual English version, published in
2004-08.
The text of this standard is based on the following documents:
CDV Report on voting
100/728/CDV 100/817/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.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
IEC 61883 consists of the following parts under the general title Consumer audio/video
equipment – Digital interface:
Part 1: General
Part 2: SD-DVCR data transmission
Part 3: HD-DVCR data transmission
Part 4: MPEG2-TS data transmission
Part 5: SDL-DVCR data transmission
Part 6: Audio and music data transmission protocol
Part 7: Transmission of ITU-R BO.1294 System B
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated 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.

Part 3: HD-DVCR data transmission

1 Scope
This part of IEC 61883 specifies the packet format and the transmission timing for HD-DVCR
data. It describes the specifications for the IEEE 1394 packet, the CIP header for 1125-60
and 1250-50 television systems, and the transmission timing.
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 amendments) applies.
IEC 61834-3, Recording – Helical-scan digital video cassette recording system using 6,35 mm
magnetic tape for consumer use (525-60, 625-50, 1125-60 and 1250-50 systems) – Part 3:
HD format for 1125-60 and 1250-50 systems

3 Abbreviations
For the purpose of this document, the following abbreviations apply:
1125-60 system: the 1125-line system with a frame frequency of 30,00 Hz
1250-50 system: the 1250-line system with a frame frequency of 25,00 Hz
HD-DVCR: high-definition digital video cassette recorder
IEEE 1394 packet: IEEE 1394 isochronous packet defined in IEC 61883-1
4 Construction of IEEE 1394 packet
4.1 Source packet structure of the HD-DVCR data stream
For the HD-DVCR data stream, the data structure for digital interface defined in IEC 61834-3,
Clause 10 is used. The source packet size for the HD-DVCR data stream is 960 bytes, divided
into 12 DIF blocks.
The correspondence between DIF blocks and source packets for the 1125-60 system and
the 1250-50 system are shown in Figure 1 and Figure 2 respectively.

4.2 Packetization of source packet of the HD-DVCR data stream
A source packet shall not be divided and shall be equal to a data block.
Data blocks transmitted in an IEEE 1394 isochronous cycle shall be determined according to
the TR value in the CIP header (see 5.2). An empty packet is placed in any cycle with no data
block.
Where the TR value is
00 (1x), one or no data block is transmitted;
01 (2x), two or no data block are transmitted;
10 (4x), four or no data block are transmitted.
The SYT field of the CIP header (see 5.1) is used to synchronize the transmitter and the
receiver.
4.3 Transmission order of video frames for high-speed transmission
Transmission order of data within one video frame is defined in Figure 1 and Figure 2. For
high-speed transmission, the transmission order of each video frame data shall follow the time
sequence.
5 CIP header
5.1 CIP header for HD-DVCR data stream
The structure of the CIP header for the HD-DVCR data stream is the same as the structure of
the CIP
