Part 1: General


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 61883-1 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 third edition of IEC 61883-1 cancels and replaces the second edition, published in 2003,
of which it constitutes a technical revision.
The significant technical changes with respect to the second edition are as follows:
– allocation of a new FMT code for the 1394 Trade Association specification ‘601 over
1394’;
– Clarification of the meaning of FMT code;
– harmonization of IEC 61883-1 with IEEE 1394.1 for speeds over S400.

Part 1: General



1 Scope and object
This part of IEC 61883 specifies a digital interface for consumer electronic audio/video
equipment using IEEE 1394. It describes the general packet format, data flow management
and connection management for audio-visual data, and also the general transmission rules for
control commands.
The object of this standard is to define a transmission protocol for audio-visual data and
control commands which provides for the interconnection of digital audio and video
equipment, using IEEE 1394.
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.
IEEE 212:2001, Standard for a Control and Status Registers (CSR) – Architecture for
microcomputer buses

IEEE 1394a:2000, Standard for a High Performance Serial Bus – Amendment 1
NOTE Throughout this document, the term “IEEE 1394” indicates a reference to the standard that is the result of
the editorial combination of IEEE 1394:1995 and IEEE 1394a:2000. Devices conforming solely to IEEE 1394:1995
may conform to IEC 61883. Devices conforming to IEC 61883 should conform to IEEE 1394a:2000.

4 High-performance serial bus layers
4.1 Cable physical layer
All cable physical layer implementations conforming to this standard shall meet the
performance criteria specified by IEEE 1394. Either the cable and connector defined in
IEEE 1394:1995, or the cables and connector defined in IEEE 1394a:2000, shall be used.
When necessary for an AV device to generate a bus reset, it shall follow the requirements of
IEEE 1394a:2000, 8.2.1. An AV device that initiates a bus reset should generate an arbitrated
(short) bus reset, as specified by IEEE 1394a:2000, in preference to the long bus reset
defined by IEEE 1394:1995.
4.2 Link layer
All link layer implementations conforming to this standard shall meet the specifications of
IEEE 1394.
4.3 Transaction layer
All transaction layer implementations conforming to this standard shall meet the specifications
of IEEE 1394.
5 Minimum node capabilities
A node shall conform to the following requirements.
– A node shall be cycle master capable. This is because every node has the possibility to be
assigned as a root.
− A node shall be isochronous resource manager capable, as specified by IEEE 1394:1995,
and shall implement the additional isochronous resource manager facilities and
responsibilities specified by IEEE 1394a:2000 in 8.3.1.5, 8.3.2.3.8, 8.3.2.3.11, 8.4.2.3 and
8.4.2.6A.
− A node which transmits or receives isochronous packets shall have plug control registers
(see 7.2).
5.1 Serial bus management
Bus manager capability is optional for AV devices, but, if implemented by devices conforming
to this standard, shall conform to IEEE 1394.
5.2 Command and status registers
5.2.1 CSR core registers
This standard conforms to the CSR architecture. Details of its registers are specified by
IEEE 1394.
The STATE_CLEAR.cmstr bit shall be implemented as specified by IEEE 1394a:2000, 8.3.2.2.1.

---------------------- Page: 14 ----------------------

SIST EN 61883-1:2009
61883-1 © IEC:2008(E) – 9 –
NOTE The cmstr bit is set automatically (see IEEE 1394a:2000, 8.3.2.2.1) by system software or hardware when
a node becomes the new root after the bus reset process is completed. In this manner, it is possible to ensure the
fast resumption and continuity of data transmission where the time scale is critical at the level of microseconds.
The rapid activation of a new cycle master decreases the likelihood of a gap in the transmission of cycle start
packets; uninterrupted transmission of cycle start packets at nominal 125 µs intervals is critical to the delivery of
isochronous data within its latency requirements.
5.2.2 Serial bus node registers
Implementation requirements for bus-dependent registers in this standard conform to
IEEE 1394. A node shall have the following registers:
CYCLE_TIME register
BUS_TIME register
BUS_MANAGER_ID register
BANDWIDTH_AVAILABLE register
CHANNELS_AVAILABLE register
A node should have the following register specified by IEEE 1394a:2000:
BROADCAST_CHANNEL register
5.2.3 Configuration ROM requirements
A node shall implement the general ROM format as defined in IEEE 1212:2001 and
IEEE 1394. Additional information required for implementations of this standard shall be
included in one of the unit directories. Figure 1 shows an example of the configuration ROM
implementation for this standard.
