CLIFF EFFECT:
video systems that describes the sudden deterioration of picture quality 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. 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: 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.
COMPONENT DIGITAL: A digital representation of a component analog signal set, most often Y, B-Y,
R-Y. The encoding parameters are specified by CCIR-601. CCIR-656 and SMPTE 125M
specify the parallel interface.
COMPOSITE ANALOG: An encoded video signal such as NTSC or PAL video, that includes
horizontal and vertical synchronizing information.
COMPOSITE DIGITAL: A digitally encoded video signal, such as NTSC or PAL video that includes
horizontal and vertical synchronizing information.
D1:
A component digital video recording format that uses data conforming to the CCIR-601
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.

signal. This is a revision of the earlier EBU Tech 3246-E standard, which was in turn
derived from CCIR-601.
EDH
Error Detection and Handling (EDH) is defined in SMPTE RP-165 as a method of
determining when bit errors have occurred along the digital video path.
RP-165, two error detection checkwords are used, one for active picture samples, and the
other on a full field of samples. Three sets of flags are used to convey information regarding
detected errors, to facilitate identification of faulty equipment or cabling. One set of flags is
associated with each checkword, and the third is used to evaluate ancillary data integrity.
The checkwords and flags are combined into a special error detection data packet that is
included as ancillary data in the serial digital signal.
