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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 62379-5-2 has been prepared by technical area 4: Digital system
interfaces and protocols of IEC technical committee 100: Audio, video and multimedia
systems and equipment.
The text of this standard is based on the following documents:
CDV Report on voting
100/2050/CDV 100/2158/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 committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

INTRODUCTION
IEC 62379 specifies the Common Control Interface, a protocol for managing networked
audiovisual equipment. The following parts exist or are planned:
1 General
2 Audio
3 Video
4 Data
5 Transmission over networks
6 Packet transfer service
7 Measurement
IEC 62379-1:2007 specifies aspects which are common to all equipment, and it includes an
introduction to the Common Control Interface.
IEC 62379-2:2008, IEC 62379-3 (under consideration) and IEC 62379-4 (under consideration)
specify control of internal functions specific to equipment carrying particular types of live
media. IEC 62379-4 refers to time-critical data such as commands to automation equipment,
but not to packet data such as the control messages themselves.
IEC 62379-5 specifies control of transmission of these media over each individual network
technology. It includes network specific management interfaces along with network specific
control elements that integrate into the control framework.
IEC 62379-5-1 specifies management of aspects which are common to all network
technologies. IEC 62379-5-3 onwards specify management of aspects which are particular to
individual networking technologies.
IEC 62379-5-2 (this standard) specifies protocols which can be used between networking
equipment to enable the setting up of calls which are routed across different networking
technologies.
IEC 62379-6 specifies carriage of control and status messages and non-audiovisual data over
transports that do not support audio and video, such as RS232 serial links, with (as for
IEC 62379-5) a separate subpart for each technology.
IEC 62379-7 specifies aspects that are specific to the measurement of the service
experienced by audio and video streams and in particular to the requirements of EBU ECN-
IPM Measurements Group.
