Glossary of Terms

Bandwidth
Describes the measure of data transfer capacity. A computer system's PCI expansion bus is
rated for a maximum peak data bandwidth of 132 MB/s. PCI devices must share the
maximum PCI bus bandwidth when transferring data to and from system memory or other
devices.
Bus
A common pathway, or channel, between multiple devices. Besides the computer's internal
bus to memory and system components, peripheral buses such as PCI and AGP, allow adding
or changing devices that make up the computer system.
Camera Link™
A digital camera interface standard based on Channel Link technology. Camera Link™
provides a standard digital camera connection specification, a standard data communication
protocol, and simpler cabling between camera and frame grabber.
Composite sync
Synchronization signals that combines the vertical component (video field or frame sync)
with the horizontal component (video line sync). Often RGB cameras, besides the three color
signals, have a fourth composite sync (CS) signal.
Composite Video
A video signal that is composed of the luminance and color information plus the
synchronization signals together. Common composite video formats are NTSC and PAL.
Driver
Also called a device driver, a program routine that links a peripheral device to the operating
system. Specific to the Bandit-II, its VGA driver is required for its display adapter
functionality and a device driver is required for its frame grabber capabilities.
Frame
One complete image data set or its equivalent storage space.
