TECHNICAL SUMMARY

The GigE Vision standard is a comprehensive document of some 300 pages that defines how compliant products interact to deliver video and control information over Ethernet networks. It has four main elements.

• Device Discovery, which defines the sequence of events required for compliant devices to obtain valid IP addresses, and for control applications to discover compliant devices.
• GigE Vision Control Protocol (GVCP), which defines how to specify video stream channels and control and configure compliant devices.
• GigE Vision Stream Protocol (GVSP), which defines how images are packetized and provides mechanisms for cameras or other types of video transmission systems to send image data and other information to compliant receivers.
• An extensible mark-up language (XML) description file, which provides the equivalent of a computer-readable data sheet of features in compliant devices. This file must be based on the schema defined by the European Machine Vision Association's GenICam® standard and include seven basic features.

The most recent version of GigE Vision, Version 1.2, allows a wide range of Ethernet-connected software and hardware products to be registered as GigE Vision-compliant offerings. They must fall under one or more of the following categories:

1. An application that functions as the master of a GVCP control channel;
2. A device controlled by GVCP;
3. A GVSP-compliant video transmitter; and
4. A GVSP-compliant video receiver.

The diagram illustrates some of the products covered by this classification system. The products in the video source section, for example, would fall into categories 2 and 3, while the software-based video processing unit would fall into 2,3, and 4.

Watch a brief video that demonstrates the new classes of products that can be registered under GigE Vision, Version 1.2.
