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 62379-3 has been prepared by technical area 4: Digital system

interfaces and protocols of IEC technical committee 100: Audio, video and multimedia

systems and equipment.
The text of this standard is based on the following documents:
FDIS Report on voting

INTRODUCTION

The IEC 62379 series specifies the common control interface, a protocol for managing

equipment which conveys audio and/or video across digital networks.
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 for EBU ECN-IPM

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 (this standard) 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 62379-5-2 specifies protocols which can be used between networking equipment to

enable the setting up of calls which are routed across different networking technologies.

IEC 62379-5-3, onwards, specify management of aspects which are particular to individual

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.

3 Terms, definitions and abbreviations
3.1 Terms and definitions

For the purposes of this document, the terms and definitions given in IEC 62379-1 apply.

4 Video format definitions
4.1 Video signal format definitions
4.1.1 General

At any point in the video signal chain, the video data will be in a particular format. For

management purposes, the format shall be identified by an object identifier, either a “Common

control interface standard” object identifier as defined in this standard or an object identifier

defined elsewhere.

NOTE Permitting video format identifiers to be defined outside this standard allows use of proprietary formats

within the standard protocol and also allows industry standard formats to emerge that may eventually be

incorporated into future revisions of this standard.
4.1.2 Video parameters
4.1.2.1 General

The definitions in 4.1.3 make reference to "parameters" which provide additional information

about the format. These parameters shall be mapped to "sub-identifier" values as specified in

the other subclauses of 4.1.2. Any parameter may be "unspecified".

The "sub-identifier" values shall be appended to the object identifiers as additional arcs, in the

order in which the parameters are listed in the relevant subclause of 4.1.3; except that if a

---------------------- Page: 13 ----------------------
SIST EN 62379-3:2015
– 8 – IEC 62379-3:2015 © IEC 2015

parameter is unspecified, and either is the last parameter or all subsequent parameters are

also unspecified, then it shall be omitted.

For all parameters, "unspecified" is coded as zero, so this rule ensures that the OID does not

end with a zero arc.

EXAMPLE If the last two parameters are vertical resolution and scan type, then 1080P would be coded as .1080.1,

1080P (with scan type unspecified) as .1080, and P (with vertical resolution unspecified) as .0.1.

4.1.2.2 Frame rate
The sub-identifier for frame rate shall be a value of the following type:
FrameRate::= Unsigned32 (0.. 2147483647)
-- An integer representing the calculated frame rate ratio of the encoded
-- video signal.
-- A value of zero shall indicate unspecified.
-- This is computed by calculating the frame rate ratio,
-- such as 24000/1001 = 23.976Hz and multiplying by 1000
-- to convert the value to an integer; in this case 23976.
-- For display purposes the value needs to be divided by
-- 1000 and a decimal point inserted as shown in the
-- Display-Hint.
4.1.2.3 Source type

The sub-identifier for the source type of the video shall be a value of the following type:

SourceType::= INTEGER {
unspecified (0),
sd (1),
hd (2),
uhd4k (3),
uhd8k (4)
} (unspecified.. uhd8k)
-- An integer representing the source type of the encoded video signal.
-- A value of zero shall indicate unspecified.
4.1.2.4 Vertical resolution

The sub-identifier for the vertical resolution shall be a value of the following type:

LineResolution::= INTEGER
-- An integer representing the vertical
-- resolution of the encoded video signal.
-- A value of zero shall indicate unspecified.
4.1.2.5 Scan type

The sub-identifier for the video scan type shall be a value of the following type:

ScanType::= INTEGER {
unspecified (0),
progressive (1),
interlaced (2),
psf (3)
} (unspecified..psf)
-- An integer representing the scan type of the encoded video signal.
-- A value of zero shall indicate unspecified.
4.1.2.6 Coding type

The sub-identifier for the video coding type shall be a value of the following type:

CodingType::= INTEGER {

} (unspecified.. h265HEVC)
-- An integer representing the coding type of the encoded video signal.
-- A value of zero shall indicate unspecified.
4.1.2.7 Source aspect ratio

The sub-identifier for the source aspect ratio shall be a value of the following type:

SourceAspectRatio::= INTEGER {
Unspecified (0),
fourByThree (43),
sixteenByNine (169),
twoPointTwoOne (221)
} (unspecified..twoPointTwoOne)
-- An integer representing the source aspect ratio of the encoded
-- video signal.
-- A value of zero shall indicate unspecified.
4.1.2.8 Active format description codes

The sub-identifier for the active format description codes shall be a value of the following type:

ActiveFormatDescriptionCodes::= INTEGER
-- An integer representing the active format description codes for
-- video used with the range of source aspect ratios.
-- The codes are from 0000-1111
-- See SMPTE ST 2016-1:2009 for code descriptions.
4.1.3 Video signal formats
4.1.3.1 Video signal format root location
Video signal formats shall be rooted at the following location in the MIB tree:
iec62379 OBJECT IDENTIFIER::= { iso(1) standard(0) 62379 }
videoFormat OBJECT IDENTIFIER::= { iec62379 video(3) format(2) }

4.2 Video transport format definitions
4.2.1 General

For management purposes, the transport format shall be identified by an object identifier,

either a “Common control interface standard” object identifier as defined in this standard or an

object identifier defined elsewhere.

NOTE Permitting video transport format identifiers to be defined outside this standard allows use of proprietary

formats within the standard protocol and also allows industry standard formats to emerge that may eventually be

incorporated into future revisions of this standard.
4.2.2 Video transport root location

Video transport formats shall be rooted at the following location in the MIB tree:

videoTransportFormat OBJECT IDENTIFIER::= { videoFormat transport(2) }

4.3 Video metadata format definitions
4.3.1 General

For management purposes, the metadata format shall be identified by an object identifier,

either a “Common control interface standard” object identifier as defined in this standard or an

object identifier defined elsewhere.

NOTE Permitting video metadata format identifiers to be defined outside this standard allows use of proprietary

formats within the standard protocol and also allows industry standard formats to emerge that may eventually be
