DEFINITIONS
24p:
A progressively scanned high definition video format with 1920 pixels and 1080 lines. (See also
description sF.)
4:2:2
The sampling ratio used in the HDTV digital video signal. For every 4 samples of luminance
there are 2 samples each of R-Y (Red minus Luminance) and B-Y (Blue minus luminance).
4:4:4
A sampling ratio that has equal amounts of the luminance and both chrominance channels.
16x9
A wide screen television format such as HDTV in which the aspect ratio of the screen is 16
units wide by 9 high as opposed to the 4x3 of normal TV.
AES/EBU: (Sometimes abbreviated as AES) Refers to the digital audio standard (AES3-1992) set by the
Audio Engineering Society and European Broadcast Union and used by most forms of digital
audio from CDs to professional digital video.
Aspect Ratio: The ratio of width to height in a picture. Theatre screens generally have an aspect ratio of
1.85 to 1, wide screen TV (16x9) is 1.77 to 1, and normal TV (4x3) is 1.33 to 1.
ATC:
See SMPTE RP188.
CCIR (International Radio Consultative Committee)
organisation is now known as ITU.)
CCIR-601: See ITU-R601.
Cliff effect:
(also referred to as the 'digital cliff') This is a phenomenon found in digital video systems
that describes the sudden deterioration of picture quality when due to excessive bit errors,
often caused by excessive cable lengths. The digital signal will be perfect even though one of
its signal parameters is approaching or passing the specified limits.
however, the parameter will reach a point where the data can no longer be interpreted
correctly, and the picture will be totally unrecognisable.
Component analog: The non-encoded output of a camera, video tape recorder, etc., consisting of the
three primary colour signals: red, green, and blue (RGB) that together convey all necessary
picture information. In some component video formats these three components have been
translated into a luminance signal and two colour difference signals, for example Y, B-Y, R-Y.
