AS NZS IEC 62676-3:2020 pdf download.Video surveillance systems for use in security applications
1 Scope
This Part of IEC 62676 specifies physical, electrical and software interface (non-IP) specifications of analog and digital video interface in video surveillance systems (so far called CCTV) applications. Video interfaces are used both for connection and transmission of surveillance video, audio and control signals. T hrough video interfaces, video surveillance systems can be put together by connecting various components such as image capturing devices, image handling devices, etc. This International Standard ensures interoperability among various video surveillance components.
This International Standard applies strictly to Video Surveillance Systems. This standard is based on broadcast television standards and other standards, and it defines the minimum requirements for analog and digital video interfaces to meet VSS's requirements,interoperability and de facto practice.

3.1.3 analog video
video signal made of a continuous electrical signal which contains the luminance (brightness) and chrominance (color) of the image
Note 1 to entry: This video signal may be carried in separate channels, as in component video (YPbPr) and S-Video, or combined in one channel, as in composite video and RF connector.
3.1.4 BNC jack
a type of connector used to input/output analog video signals, component video signals and serial digital video signals, with the female electrical contact or socket, and is the "more fixed" connector of a connector pair
Note 1 to entry: Relevant specifications can refer to IEC 61169-8.
3.1.5 channel
one or more streams of video, audio and/or metadata that together constitute a unique entity for the purpose of surveillance
3.1.6 color depth
pixel depth
the number of bits used to represent the color of a single pixel in a bitmapped image or video frame buffer
3.1.7 component
a software or hardware object, meant to interact with other components, encapsulating certain functionality or a set of functionalities with clearly defined interfaces and conforming to a prescribed behaviour common to all components within a standard
3.1.17 displayPort
a digital display interface standard put forth by VESA which defines a digital audio/video interconnect used primarily between a computer and its display, or a computer and a home-theater system.AS NZS IEC 62676-3 pdf download.
