OVERVIEW
Model 8950-SID Digital Source ID Decoder Manual
EBU TECH 3267-E: The EBU recommendation for the parallel interface
of 625 line digital video signal. This is a revision of the earlier
EBU Tech 3246-E standard that was in turn derived from CCIR-
601.
EDH Error Detection and Handling (EDH) is defined in SMPTE
RP-165 as a method of determining when bit errors have
occurred along the digital video path. According to RP-165, two
error detection checkwords are used, one for active picture
samples, and the other on a full field of samples. Three sets of
flags are used to convey information regarding detected errors,
to facilitate identification of faulty equipment or cabling. One set
of flags is associated with each checkword, and the third is used
to evaluate ancillary data integrity. The checkwords and flags
are combined into a special error detection data packet that is
included as ancillary data in the serial digital signal.
EMBEDDED AUDIO: Digital audio is multiplexed onto a serial digital video
data stream.
ITU: The United Nations regulatory body governing all forms of
communications. ITU-R (previously CCIR) regulates the radio
frequency spectrum, while ITU-T (previously CCITT) deals with
the telecommunications standards.
ITU-R601: See CCIR601
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.
RESOLUTION:
the resolution of the signal. Eight bits is the minimum resolution
for broadcast television signals.
4 bits = a resolution of 1 in 16.
8 bits = a resolution of 1 in 256.
10 bits = a resolution of 1 in 1024.
SERIAL DIGITAL:
Often used informally to refer to serial digital television signals.
SMPTE (Society of Motion Picture and Television Engineers): A
professional organization that recommends standards for the
film and television industries.
SMPTE 125M:
for component video signals.
parameters required to generate and distribute component
video signals on a parallel interface.
