Glossary
• Band
One of the surfaces of a buffer. A grayscale image requires just one band. A color
image requires three bands, one for each color component.
• Bandwidth
A term describing the capacity to transfer data. Greater bandwidth is needed to
sustain a higher transfer rate. Greater bandwidth can be achieved, for example, by
using a wider bus.
• Blanking period
The portion of a video signal after the end of a line or frame, and before the
beginning of a new line or frame. During this period, the video signal is "blank"
so that a scan line can be brought back to the beginning of the new line or frame.
• Bus
A pathway along which signals are sent, generally in two directions, for
communication of data.
• Color component
One of the components that make up a color space. Typically, each component
of a color image is stored in a separate band of a multi-band buffer.
• Color space
A color space is a way of representing and describing the complete range of
perceived colors. A number of color spaces have been developed. Common color
spaces are RGB and HSL. Both describe the same range of perceivable colors.
• Composite synchronization
A synchronization signal made up of two components: one horizontal and one
vertical.
