Overview

EN 61883-3:2005 (IEC 61883-3:2004) defines the digital-interface rules for HD-DVCR data transmission over IEEE 1394 (FireWire) in consumer audio/video equipment. The standard specifies packet formats, the Common Isochronous Packet (CIP) header fields for two high-definition television systems (1125-60 and 1250-50), and precise transmission timing requirements to ensure reliable, synchronized high‑definition recording and playback.

Key topics and technical requirements

• Packet structure
  • Source packet size: 960 bytes, composed of 12 DIF blocks. A source packet is not divided and is treated as a single data block.
  • Packetization rules reference the IEC 61834-3 data stream structure.
• IEEE 1394 / CIP integration
  • Defines how HD-DVCR source packets are encapsulated into IEEE 1394 isochronous packets.
  • CIP header fields are specified for both systems (1125-60 and 1250-50). Example fields: DBS, FN, QPC, SPH, FMT, 50/60, STYPE and TR.
  • DBS (data block size) and STYPE values are adjusted for HD data; STYPE = 00010 (binary) and DBS = 11110000 (binary) for the HD formats.
  • TR (transmission rate selector) values control how many data blocks are carried per cycle: 00 = 1x, 01 = 2x, 10 = 4x.
  • DBC (data block counter) increments are aligned with TR (increment by 1 for 1x, multiples of 2 for 2x, multiples of 4 for 4x).
• Synchronization and timing
  • The SYT field in the CIP header carries a timestamp once every video frame for transmitter/receiver synchronization.
  • Transmission delay limit: 450 µs for timestamp and packet arrival constraints.
  • Isochronous packet scheduling requires K packets per video frame without empty packets: K = 250 for 1125-60 and K = 300 for 1250-50.
  • High-speed (Hx) transmission groups H data blocks per packet; isochronous packet n contains data blocks nH ... (n+1)H–1.

Applications and practical value

• Ensures interoperability between HD-DVCR hardware (recorders/players) and IEEE 1394 interfaces.
• Used by:
  • Consumer electronics manufacturers (HD camcorders, HD-DVCRs)
  • Firmware and driver developers for IEEE 1394 isochronous streaming
  • System integrators building HD recording/playback chains
  • Test labs and certification bodies validating timing, packet formats, and SYT synchronization
• Helps implement robust, low-latency HD recording over FireWire and supports compatibility with IEC 61834 HD tape formats.

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.
