Composite digital:
A digitally encoded video signal, such as NTSC or PAL video that includes
horizontal and vertical synchronizing information.
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.
Embedded audio:
Digital audio is multiplexed onto a serial digital video data stream.
Gen lock: In order to derive the 6 Hz relationship between 23.98 Fps and 29.97 Fps frame boundaries,
and to ensure that the timecode to 6 Hz relationship is fixed, an NTSC colour black video
reference must be supplied to the HDHD9010-SIE Film Footage Encoder. Normally, the gen
lock signal is the colour black system reference to which the 24p tri-level sync generator is gen
locked.
The gen lock reference is only necessary when the system video type is
1080p/23.98sF.
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: An international standard for standard definition component digital television from which was
derived SMPTE 125M and EBU 3246-E standards. ITU-R601 defines the sampling systems,
matrix values and filter characteristics for both Y, B-Y, R-Y and RGB component digital
television signals.
ITU-R709: An international standard for High definition component digital television from which was
derived SMPTE 274M and SMPTE 296M standards. ITU-R709 defines the sampling systems,
matrix values and filter characteristics for both Y, B-Y, R-Y and RGB component digital
television signals.
