18、E FOR NETWORKED DIGITAL AUDIO AND VIDEO PRODUCTS Part 3: Video 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
19、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 referre
20、d 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 t
21、his 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 internatio
22、nal 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
23、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 Publi
24、cations 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.
25、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)
26、 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 cos
27、ts (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 applic
28、ation 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 technica
29、l area 4: Digital system interfaces and protocols of IEC technical committee 100: Audio, video and multimedia systems and equipment.

A list of all parts in the IEC 62379 series, published under the general title Common control interface for networked digital audio and vi
31、deo products, can be found on the IEC website. IEC 62379-3:2015 IEC 2015 5 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 thi
32、s date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 6 IEC 62379-3:2015 IEC 2015 INTRODUCTION The IEC 62379 series specifies the common control interface, a protocol for managing equi
33、pment 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
34、, 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
35、 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 tha
36、t 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 technolo
37、gies. 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 fo
38、r 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.

39、CE FOR NETWORKED DIGITAL AUDIO AND VIDEO PRODUCTS Part 3: Video 1 Scope This part of IEC 62379 details aspects of the common control interface specified in IEC 62379-1 that are specific to video. 2 Normative references The following documents, in whole or in part, are normatively referenced in this
40、document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 62379-1:2007, Common control interface for networked audio and video products Part 1
41、: General 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. 3.2 Abbreviations EBU ECN-IPM European Broadcasting Union Expert Community Network and Infrastructure Internet Protocol Measurement HD H
42、igh Definition OID Object Identifier PSF Progressive Segmented Frame SD Standard Definition UHD Ultra High Definition 4 Video format definitions 4.1 Video signal format definitions General 4.1.1 At any point in the video signal chain, the video data will be in a particular format. For management pur
43、poses, 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
44、formats within the standard protocol and also allows industry standard formats to emerge that may eventually be incorporated into future revisions of this standard. Video parameters 4.1.2General 4.1.2.1 The definitions in 4.1.3 make reference to “parameters“ which provide additional information abou
45、t 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
46、the relevant subclause of 4.1.3; except that if a 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
47、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. Frame rate 4.1.2.2 The sub-identifier for frame rate shall
48、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 m
49、ultiplying 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. Source type 4.1.2.3 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
