Gigabit Ethernet Vision
Source: Wikipedia, the free encyclopedia
Vision GigE Vision® is a camera interface standard developed using
the Gigabit Ethernet communication protocol. Introduced in 2006 for high-performance
industrial cameras, the GigE Vision standard protocol is a featured option in many of FastVision’s
newest cameras, primarily in the CCD family of products. GigE provides a framework for transmitting
high-speed video and related control data over Ethernet
networks. GigE Vision is a registered trademark of the AIA.
GigE Vision is based on the Internet
Protocol standard. The standard is trying to unify protocols currently used
in machine vision industrial cameras and let 3rd party organizations develop
compatible software and hardware.
Features of the GigE Vision standard:
- Fast data transfer rates - up to 1000Mbit/s
- Data transfer length up to 100m (some producers claim
even 150m). The use of switches, repeaters or fiber optic converters can
increase the length.
- Based on established standard allowing networking with
other Ethernet devices and computers.
- Delivers a standardized environment for the delivery of
new-generation, networked video applications based on switched
client/server Ethernet architectures.
GigE Vision has four main elements:
- GigE Vision Control Protocol(GVCP). Runs on the UDP protocol. The standard defines how
to control and configure devices. Specifies stream channels and the
mechanisms of sending image and configuration data between cameras and
- GigE Vision Stream Protocol(GVSP). Runs on the UDP protocol. Covers the definition of
data types and the ways images can be transferred via GigE;
- GigE Device Discovery Mechanism. Provides mechanisms to
obtain IP addresses;
- An XML description file based on a schema defined by
the European Machine Vision Association's GenICam
standard. A datasheet that allows access to camera controls and image
