complete Frame). Only 576 of these lines are used for picture. The rest are used for sync or
extra information such as VITC and Teletext.
Pixel: The smallest distinguishable and resolvable area in a video image. A single point on the
screen. In digital video, a single sample of the picture. Derived from the words picture
element.
Serial digital: Digital information that is transmitted in serial form. Often used informally to refer to
serial digital television signals.
SMPTE (Society of Motion Picture and Television Engineers): A professional organisation that
recommends standards for the film and television industries.
SMPTE 12M: The SMPTE standard for Time and address code. SMPTE 12M defines the
parameters required for both linear and vertical interval time codes.
SMPTE 125M: The SMPTE standard for bit parallel digital interface for component video signals.
SMPTE 125M defines the parameters required to generate and distribute component video
signals on a parallel interface.
SMPTE 259M-C: The SMPTE standard for 525 and 625 line serial digital component and composite
interfaces.
SMPTE 272M: The SMPTE standard for embedding audio in serial digital standard definition
(SMPTE 259M-C) video signals.
SMPTE 274M: The SMPTE standard for bit parallel digital interface for high definition component
video signals with an active picture of 1080 lines x 1920 pixels.
SMPTE 276M: The SMPTE standard for transmission of AES/EBU Digital Audio Signals Over
Coaxial Cable
SMPTE 292M: The SMPTE standard for high definition serial digital component interfaces.
SMPTE 296M: The SMPTE standard for bit parallel digital interface for high definition component
video signals with an active picture of 720 lines x 1280 pixels.
SMPTE 299M: The SMPTE standard for embedding audio in serial digital high definition
(SMPTE 292M) video signals.
TRS: Timing reference signals used in composite digital systems. (It is four words long).
TRS-ID: Abbreviation for "Timing Reference Signal Identification". A reference signal used to
maintain timing in composite digital systems. (It is four words long.)
