This standard defines procedures for communication between network video clients and video transmitter devices. This new set of specifications makes it possible to build network video systems with devices and receivers from different manufacturers using common and well defined interfaces. These interfaces cover functions such as media and imaging configuration, real-time streaming of audio and video, Pan, Tilt and Zoom (PTZ) control as well as analytics. The management and control interfaces defined in this standard are described as Web Services. This standard also contains XML schema and Web Service Description Language (WSDL) definitions for the introduced network services.
