4.4. GigE Interface
GigE Vision
®
is a camera interface standard that uses the Gigabit Ethernet (GigE)
communication protocol. It provides a framework for transmitting high-speed video and
related control data over Ethernet networks.
To realize the GigE communication the Bobcat-640-GigE cameras are equipped with a
1000Base-T Ethernet interface (RJ-45 connector). The data connection between camera and
PC can be established via a standard CAT5e cable.
The GigE Vision standard defines how compliant products interact to deliver video and control
information over Ethernet networks. It has the following four main elements:
Device discovery
: defines the sequence of events required for compliant devices to
obtain valid Internet Protocol addresses, and for control applications to discover compliant
devices.
GigE Vision control protocol (GVCP)
: defines how to specify video stream channels and
control and configure compliant devices.
GigE Vision stream protocol (GVSP)
: 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
: provides the equivalent of a
computer-readable data sheet of features in compliant devices. This file must be based on
