This part of IEC 62676 introduces an IP network interface for devices in survillance 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.
