sync and multiplexing schemes used in both parallel and serial
interfaces. It reflects definitions found in EBU Tech 3267 (for
625 line systems) and SMPTE 125M (parallel 525 line systems)
and SMPTE 259M (serial 525 line systems).
CLIFF EFFECT
phenomenon found in digital video systems that describes the
sudden deterioration of picture quality when done 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 CCIR-601. The parallel interface is
specified by CCIR-656 and SMPTE 125M.
COMPOSITE ANALOG:
PAL video, that includes horizontal and vertical synchronizing
information.
COMPOSITE DIGITAL:
NTSC or PAL video that includes horizontal and vertical
synchronizing information.
