Video surveillance systems for use in security applications – Part 2-1: Video transmission protocols – General requirements
|Publication Date:||1 November 2013|
|ICS Code (Alarm and warning systems):||13.320|
This part of IEC 62676 introduces an IP network interface for devices in surveillance applications. This International Standard specifies a network protocol for the full interoperability of video devices. On top of the basic layers protocols are defined to accomplish the full interoperability of video devices. In surveillance applications IP video devices have to use standardized protocols to accomplish following functionality: video streaming, stream control, event handling, discovery, capability description, device management, PTZ control, auxiliaries and other functions.
Some areas of this transmission standard are covered by more than one approach, e.g. ZeroConf and WS-Discovery.
The network protocols recommended and defined by this video transmission standard are selected with a sense for future relevance and further extensions.
Video transmission equipment may be combined with additional functions, e.g. for audio or metadata transmission.
