Part 7: Measurements

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 62379-7 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:

The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,

INTRODUCTION
IEC 62379 specifies the common control interface, a protocol for managing equipment which
conveys audio and/or video across digital networks.
An introduction to the common control interface is given in IEC 62739-1.
This part of IEC 62379 specifies those aspects that are specific for using the block structure
as defined in IEC 62379-1, for standardising the collection method of audio and video
parameters for use by the European Broadcasting Union Expert Communities Networks –
Internet Protocol (IP) Measurements (EBU ECN-IPM) Group.
The collection of network related parameters may be outside the scope of this standard.
These are expected to be collected from the standard Internet Engineering Task Force (IETF)
Management Information Base (MIBs) that are generally present in most (if not all) networked
equipment. Some specific network parameters are included that are not obtainable from
existing standard IETF MIBs.
Structure of the family of standards
IEC 62379 specifies the common control interface, a protocol for managing networked
audiovisual equipment. It is intended to include the following Parts:
Part 1: General
Part 2: Audio
Part 3: Video
Part 4: Data
Part 5: Transmission over networks
Part 6: Packet transfer service
Part 7: Measurement
Part 1 specifies aspects which are common to all equipment.
Parts 2 to 4 specify control of internal functions specific to equipment carrying particular types
of live media. Part 4 does not refer to packet data such as the control messages themselves.
Part 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.
Part 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 with Part
5) a separate subpart for each technology.
Part 7 specifies those aspects that are specific to the measurement requirements of the EBU
ECN-IPM Group.
An introduction to the common control interface is given in IEC 62739-1.
Description, aims and requirements of the EBU ECN-IPM Group
In recent years, EBU members have been increasingly adopting IP networks for the
contribution of audio and video in real-time. It is well known that although IP networks are of
lower cost and provide more flexibility compared with circuit switched networks, they suffer

from longer delays and have much larger jitter, while broadcasters’ tolerance to these
variables is much less than that of normal business IT traffic.
To respond to Members’ use of IP, EBU set up two groups, Expert Communities Networks
Audio contribution over IP (ECN-ACIP) and Expert Communities Networks − Video
contribution over IP (ECN-VCIP), with the tasks of drawing up recommended codes of

Figure 1 – Relationships between ECN groups ACIP, VCIP and IPM
It was also recognised that there would be a strong demand for tools that would enable
broadcasters to measure and manage their IP networks properly to suit the many time-critical
broadcast applications they would be subjected to. To this end, the ECN-IPM (IP
measurement) group was set up. The relationships between these three groups are shown in
Figure 1.
The goals of ECN-IPM Group were to
– define a quality of service classification to achieve requested A/V transmission quality for
broadcast applications,
– standardise network information exchange between EBU members and Telecom suppliers,
– propose a method of collecting end-to-end performance information for management
purposes.
In achieving these goals the ECN-IPM Group has specified a set of parameters that are
important for broadcasters when using IP networks for audio and video transmission and has
developed a software mechanism to probe a network for device and topology discovery,
physical path tracing for both end-to-end communication and multicast streams, with the
potential for multilayer monitoring for streams on a multi-vendor network
