26、 SECURITY APPLICATIONS Part 2-2: Video transmission protocols IP interoperability implementation based on HTTP and REST services FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Na
27、tional 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, Pub
28、licly 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-gover
29、nmental 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 o
30、n 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 accepte
31、d 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
32、 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 latte
33、r. 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
34、 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
35、 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 th
36、e 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.
37、 International Standard IEC 62676-2-2 has been prepared by IEC technical committee 79: Alarm and electronic security systems. The text of this standard is based on the following documents: FDIS Report on voting 79/436/FDIS 79/449/RVD Full information on the voting for the approval of this standard c
38、an be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 62676-2-2 IEC:2013 5 A list of all parts in the IEC 62676 series, published under the general title Video surveillance systems for use in security ap
39、plications, can be found on the IEC website. 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 related to the specific publication. At this date, the publication will
40、be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 62676-2-2 IEC:2013 INTRODUCTION The IEC Technical Committee 79 in charge of alarm and electronic security systems together with many governmental organisations, test houses and equipment manufacturers have defined a common frame
41、work for video surveillance transmission in order to achieve interoperability between products. The IEC 62676 series of standards on video surveillance system is divided into 4 independent parts: Part 1 System requirements Part 2: Video transmission protocols Part 3: Analog and digital video interfa
42、ces Part 4 : Application guidelines (to be published) Each part has its own clauses on scope, references, definitions and requirements This IEC 62676-2 series consists of 3 subparts, numbered parts 2-1, 2-2 and 2-3 respectively: IEC 62676-2-1, Video transmission protocols General requirements IEC 62
43、676-2-2, Video transmission protocols IP interoperability implementation based on HTTP and REST services IEC 62676-2-3, Video transmission protocols IP interoperability implementation based on Web services This second subpart of this IEC 62676-2 series covers IP interoperability implementation based
44、 on HTTP and REST services. It is based on the requirements for IP video transmission protocols covered in IEC 62676-2-1, which defines protocol requirements to be fulfilled by any high-level IP video device interface. 62676-2-2 IEC:2013 7 VIDEO SURVEILLANCE SYSTEMS FOR USE IN SECURITY APPLICATIONS
45、Part 2-2: Video transmission protocols IP interoperability implementation based on HTTP and REST services 1 Scope This part of IEC 62676 specifies a compliant IP video protocol based on HTTP and REST services. Video transmission devices are often equipped with web servers that respond to HTTP reques
46、ts. The HTTP response may contain XML content (for GET actions), XML response information (for SET actions), or various text/binary content (for retrieval of configuration data, etc.). REST is an approach to creating services that expose all information as resources in a uniform way. The ease of usi
47、ng REST is its uniform interface for operations. Since everything is represented as a resource, create, retrieve, update, and delete (CRUD) operations use the same URI. This specification leverages the features of HTTP and REST for IP video transmission. A video transmission device supporting compli
48、ance to the requirements of this standard based on HTTP and REST Services as described in this document is declared as compatible to IEC 62676-2 HTTP and REST interoperability. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are in
