A/B roll edit
An edit in which two or more players are used to
create special effects such as dissolve and wipe, and
one recorder is used to record the results of the edit.
Using an editing controller allows efficient control c
the VTRs and very precise editing.
B-Y signal
A chrominance signal determined by subtracting the
Y (luminance) signal from the B (blue) signal. One
of the component signals.
Bridging connection
A connection which allows a signal input to an inpu
terminal to pass through the unit and exit from an
output terminal as input to external equipment. Aisc
called loop-through connection.
Capstan
A drive mechanism that moves the tape at a specific
speed. Its rotation normally synchronizes with a
reference sync signal.
Chrominance signal
Color signal containing color information such as
hue and saturation. Also called C signal.
Color frame
The color subcarrier phase, whose one cycle consist;
of two frames (four fields) in NTSC format and four
frames (eight fields) in PAL format.
Color framing
Maintenance of continuity in the color subcarrier
phase between one frame and the next, for the
purpose of avoiding noise on the picture.
Component signal
A video signal consisting of a luminance signal (Y)
and two chrominance signals (R-Y, B-Y).
Composite signal
A composite video signal containing video, burst am
sync signals.
A-6 (E) Appendixes
CTL
Abbreviation of control signal. A pulse signal
recorded on a longitudinal track of the tape in units of
fields. Counting this signal allows the number of
frames to be used to display the tape running time. It
is also used as a control signal to adjust the
relationship between the scanning position of the
video heads and tape movement during playback to
match that during recording.
Drop frame mode
In NTSC format, the actual number of frames per
second is approximately 29.97, while that for the
time code is specified as 30. Drop frame mode is a
mode in which the time code is advanced in such a
way that the difference in frame value between real
time and the time codes is corrected. In this mode,
two frames are skipped at the beginning of each
minute, except for every tenth minute, so that the
frame value for time codes matches that for real time.
EE mode
Abbreviation of Electric to Electric mode. Video and
audio signals are supplied to the VTRs internal
circuits, but not to the recording heads.
External synchronization
Synchronization of the signals and tape transport of a
VTR with those of a reference VTR.
IRE
A unit for expressing video level as determined by
the Institute of Radio Engineers (now called the
Institute of Electrical and Electronic Engineers).
LNG recording
Abbreviation of longitudinal recording. A method of
recording audio signals by radio frequency bias
method on the longitudinal track of the tape using the
fixed head.
LTC
Abbreviation of Longitudinal Time Code. A time
code recorded in a separate track at the edge of the
tape.
