BIT PARALLEL:
Byte-wise transmission of digital video down a multi-conductor cable where each
pair of wires carries a single bit. This standard is covered under SMPTE 125M, EBU 3267-E
and CCIR 656.
BIT SERIAL: Bit-wise transmission of digital video down a single conductor such as coaxial cable. May
also be sent through fiber optics. This standard is covered under SMPTE 259M and CCIR 656.
BIT STREAM: A continuous series of bits transmitted on a line.
BYTE: A complete set of quantized levels containing all the bits. Bytes consisting of 8 to 10 bits per
sample are typical in digital video systems.
CABLE EQUALIZATION:
compensate for high frequency losses in coaxial cable.

CCIR-601:

television from which was derived SMPTE 125M and EBU 3246-E standards.

RGB component digital television signals.

blanking, 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: (also referred to as the 'digital cliff') This is a phenomenon found in digital 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 unrecognisable.
COMPONENT ANALOG:
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:
R-Y. The encoding parameters are specified by CCIR-601. The parallel interface is specified
by CCIR-656 and SMPTE 125M.
COMPOSITE ANALOG:
horizontal and vertical synchronising information.
COMPOSITE DIGITAL:
horizontal and vertical synchronising 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.)
