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 doe 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. At a given moment
however, the parameter will reach a point where the data can no
longer be interpreted correctly, and the picture will be totally
unrecognizable.
COMPONENT ANALOG:
tape recorder, etc., consisting of the three primary colour
signals: red, green, and blue (RGB) that together convey all
necessary picture information.
formats these three components have been translated into a
luminance signal and two colour difference signals, for example
Y, B-Y, R-Y.
COMPONENT DIGITAL:
analog signal set, most often Y, B-Y, R-Y.
parameters are specified by ITU-R601. ITU-R656 and SMPTE
125M specify the parallel interface.
COMPOSITE ANALOG:
PAL video, that includes horizontal and vertical synchronizing
information.
COMPOSITE DIGITAL:
NTSC or PAL video that includes horizontal and vertical
synchronizing information.

conforming to the ITU-R601 standard.

tape. (Often used incorrectly to refer to composite digital video.)
D3:
A composite digital video recording format that uses data
conforming to SMPTE 244M. Records on 1/2" magnetic tape.
DAYLIGHT SAVING TIME: The civil time observed when daylight saving
time is adopted in a country or region. It is usually standard
time + 1 hour. (see also Standard Time)

recommendations for the 625/50 line television systems.
