Aspect ratio - The width-to-height ratio of an image. A 4:3 aspect ratio means the
horizontal size is a third again wider than the vertical size. Standard television
ratio is 4:3 (or 1.33:1). Widescreen DVD and HTDV aspect ratio is 16:9 (or
1.78:1). Common film aspect ratios are 1.85:1 and 2.35:1. Aspect ratios
normalized to a height of 1 are often abbreviated by leaving off the :1.
Bandwidth - Strictly speaking, the range of frequencies (or the difference
between the highest and the lowest frequency) carried by a circuit or signal.
Loosely speaking, the amount of information carried in a signal. Technically,
bandwidth does not apply to digital information; the term data rate is more
accurate.
Bit stream - Digital data, usually encoded, designed to be processed sequentially
and continuously.
Brightness - Defined by the CIE as the attribute of a visual sensation according to
which area appears to emit more or less light. Loosely, the intensity of an image or
pixel, independent of color; that is, its value along the axis from black to white.
Caption - A textual representation of the audio information in a video program.
Captions are usually intended for the hearing impaired, and therefore include
additional text to identify the person speaking, off-screen sounds, and so on.
Cb, Cr - The components of digital color-difference video signals carrying blue
and red color information, where the brightness (Y) has been subtracted from the
blue and red RGB signals to create B-Y and R-Y color-difference signals.
CD - Short for compact disc, an optical disc storage format.
CD-R - An extension of the CD format allowing data to be recorded once on a disc
by using dye-sublimation technology.
CD-ROM - Compact disc read-only memory. An extension of the Compact disc
digital audio (CD-DA) format that allows computer data to be stored in digital
Chapter - In DVD-Video, is a division of a title. Technically called part of the
