32、ny governmental organisations, test houses and equipment manufacturers have defined a common framework 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

33、 System requirements Part 2: Video transmission protocols Part 3: Analog and digital video interfaces 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,

34、 2-2 and 2-3 respectively: IEC 62676-2-1, Video transmission protocols General requirements IEC 62676-2-2, 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 servi

35、ces This second subpart of this IEC 62676-2 series covers IP interoperability implementation based 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 d

36、evice interface. BS EN 62676-2-2:201462676-2-2 IEC:2013 7 VIDEO SURVEILLANCE SYSTEMS FOR USE IN SECURITY APPLICATIONS 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

37、 on HTTP and REST services. Video transmission devices are often equipped with web servers that respond to HTTP requests. 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.

38、). REST is an approach to creating services that expose all information as resources in a uniform way. The ease of using 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 specific

39、ation leverages the features of HTTP and REST for IP video transmission. A video transmission device supporting compliance 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 Nor
