Glossary
Artifacts:
An anomaly that occurs on a video image as a result of a problem in the film-to-video transfer. Often occurs
when trying to compress too much information on to the disc.
Aspect Ratio:
The width-to-height ratio of a television screen. Widescreen is 16:9, while the standard television aspect ratio is
expressed 4:3.
Audio Streams:
DVD has the ability to hold a maximum of eight audio streams on a single disc. Usually used for multiple
languages and/or the director’s commentary.
Camera Angles:
DVD can support up to nine different camera angles. Discs that include “angles” let you watch scenes from
different camera angles for a different prospective.
Chapters:
An easy way to organize what’s on your DVD. Just like in a book, DVDs are split into chapters for easy referral
and access.
Coaxial A/V Connection:
The traditional RF connection for a Video signal. All DVD Players will have a coaxial output for purposes of
hooking up to televisions without separate audio/video inputs.
Coaxial Connection:
A type of connection used for consumer digital audio, which uses an RCA jack. The coaxial cable is an
impedance-constant, two-conductor cable with either a stranded or solid core. For DVD digital audio, use a
coaxial cable that has an impedance of 75-ohms (with 75-ohm connectors).
Component Video:
Component video offers the highest video quality available on DVD. Component video is a 3-channel system
that is either RGB or color-difference. DVD component video is color-difference. Signals using color-difference
contain the color component of the picture minus the brightness component. Component video is often
regarded as being the next step beyond S-video that can be found on the majority of DVD players, the benefits
include improved color accuracy and less color bleeding.
Component Video Output:
3 RCA or BNC connectors for the transfer of Component Video signal to TV or projector.
Composite Video:
An analog signal that contains the combined signals for luminance (black and white) and chrominance (color)
components. This is the standard for broadcast TV, VHS and Laser disc.
All DVD players have this type of output. S-Video offers a better picture while Component video offers the best
picture quality.
Composite Output:
Traditional RF type signal. All DVD players have this type of output since not all TV's have S-video or
Component Video inputs.
Deleted Scenes:
Deleted Scenes are usually scenes that are removed from a program, for various reasons. Many times deleted
scenes are reinserted into the film and the film is then called a "director's cut" or an "extended cut".
Digital Comb Filter:
To produce highly accurate Chrominance and Luminance signal separation, the chrominance and luminance
signals are converted to a digital medium. This produces enhanced color purity and reduced dot craw.
