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 244M:
The SMPTE standard for bit parallel digital interface for composite video signals.
SMPTE 244M defines the parameters required to generate and distribute composite video
signals on a parallel interface.
SMPTE 259M:
The SMPTE standard for 525 and 625 line serial digital component and composite
interfaces.
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 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.
sF:
(Also known as segmented frame) The picture is progressively scanned, however divided into
two segments, containing the odd and even lines. The segments are then sent out the serial
digital interface in the same way that the fields of an interlaced video signal are. This format is
often used at nominal frame rates of 24, 25 or 30 frames per second.
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.)
User bits: 32 bits in the time code are user assignable. They typically are used to contain reel numbers,
scene and take numbers, or other user-oriented data.
Vertical interval time code: A digital code used for timing and control purposes on video tape which is
recorded in the vertical blanking interval of the standard definition video picture, and is referred
to as VITC. Each 90 bit code word is associated with one television field, and consists of 26
time bits, 6 flag bits, 32 user bits, 18 sync bits, and an 8 bit error check (CRC) code. See also
SMPTE 12M.
White flag:
A white pulse recorded on one or more lines in the vertical interval on the first video field of
a new picture. This pulse is normally used on 24 frame per second transfers to NTSC video
that will end up on video disc recorders. This pulse allows the disc recorder to match the disc
frames to the 2/3 pulldown automatically, ensuring jitter free playback when the recorder is
parked on a single frame.
