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. 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.
COMPONENT DIGITAL:
analog signal set, most often Y, B-Y, R-Y. The encoding 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.
D1:
A component digital video recording format that uses data
conforming to the ITU-R601 standard. Records on 19 mm magnetic tape.
(Often used incorrectly to refer to component digital video.)
D2:
A composite digital video recording format that uses data
conforming to SMPTE 244M. Records on 19 mm magnetic 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.
DSO: (Daylight Saving time Observed)
