D1:
A component digital video recording format that uses data conforming to the ITU-R601
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.
D5:
A component digital video recording format that uses data conforming to the ITU-R601
standard. Records on 1/2" magnetic tape.
HD-D5:
A component digital video recording format that uses data conforming to the ITU-R709
standard. Records on 1/2" magnetic tape.
Drop frame: In NTSC systems, where the frame rate is 29.97002618 frames per second, the drop frame
mode permits time of day indexing of the frame numbers by dropping certain frame numbers.
Specifically, frames 0, and 1 at the beginning of each minute except minutes 0,10,20,30,40, &
50, are omitted, to compensate for an approximate timing error of 108 frames (3 seconds 18
frames) per hour. A flag bit is set in the time code to signal when the drop frame mode is in
effect.
EBU (European Broadcasting Union):
activities provides technical recommendations for the 625/50 line television systems.
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
ITU-R601.
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 check words 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
check word, and the third is used to evaluate ancillary data integrity. The check words 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.
Edge number:
The manufacturers of motion picture film stock print a frame identifying number along
the edge of the film, during the manufacturing process. These numbers, also known as KEY
NUMBERS, occur at one foot, or half-foot intervals, hence they have also become known as
footage numbers. The film frames between the edge numbers are identified by interpolation
from one edge number to the next. (Also see KeyKode)
Traditionally, these numbers have been only human-readable. The task of properly identifying
the correct number is somewhat tedious, and prone to error, so much care must be taken in
establishing the reference frame's number.
