Glossary 47
• LVD S.
Low-voltage differential signaling. LVDS offers a general-purpose, high bandwidth
interface standard for serial and parallel data interfaces that require increased
bandwidth at high speed, with low noise and power consumption.
•PCIe.
Peripheral Component Interconnect Express. The standard used for the computer
bus that acts as an interface between hardware devices, such as Matrox
Radient eV-CXP, and your computer.
• Payload.
The amount of data transmitted to the PCIe bus within each data packet.
Common payload sizes are 128, 256, 512, 1024, 2048, and 4096 bytes.
•PoCXP.
Power-over-CoaXPress. Power-over-CoaXPress is the term for power transmitted
to a video source over a coaxial cable using the CoaXPress standard. Power can be
provided to a video source, at up to 13 W per cable, at a nominal voltage of 24 V.
• Real-time processing.
The processing of an image at the same speed or faster than the speed at which
images are grabbed. Real-time processing ensures that no frames are missed.
Also known as live processing.
•Rotary encoder.
A device used to convert the angular position of a shaft or axle to an analog or
digital code.
