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.
DARS (A Digital Audio Reference Signal): A reference signal conforming to the format and
electrical specification of the AES3-1992 standard, but often has only the preamble
active. This signal is used for synchronization in digital audio studio applications. The
recommended practice AES11-1997 gives further information on the use of a DARS
reference.
