code. Using this mode produces a 
difference of approximately 86 
seconds per day between real time 
and time code, which causes 
problems when editing programs in 
units of seconds using the number of 
frames as a reference.
NTSC
Abbreviation for National Television 
System Committee. NTSC is a color 
TV broadcasting system adopted 
mainly in North American countries, 
and in parts of Asia and Central and 
South America.
PAL
Abbreviation for Phase Alternating 
Line.PAL is a color TV broadcasting 
system developed by Telefunken 
GmbH of Germany. This system is 
adopted mainly in European 
countries, in Australia, and in parts of 
Asia and South America.
Progressive scan mode
A scanning method in which odd 
rows and even rows are read at the 
same time. Also called full-screen 
scanning.
Reference video signal
A video signal that contains a sync 
signal or sync and burst signals, used 
as a reference for synchronization of 
video equipment.
Return video
Video signals that are sent back from 
a VTR to a camera or from a control 
console to a camera so that a camera 
operator can verify the recorded/
selected video signals.
Sampling frequency
A method used to sample an analog 
signal so that it can be represented 
digitally. The higher the sampling 
frequency is, the more accurately the 
high-frequency analog signal can be 
represented.
SDI
Serial Digital Interface. An interface 
standardized as SMPTE 259M which 
enables the transmission of an 
uncompressed digital component 
stream.
Servo
A mechanism that controls the 
number and phase of revolutions of 
the head drum, capstan, or reel tables. 
The servo mechanism allows 
recording and playback of the video 
signal without guard band noise. The 
reference signal of the servo control 
is normally a vertical sync signal.
Shot data
Data recorded, while shooting, in the 
color bars, the user bits data of VITC, 
and so forth. Includes the model 
name, serial number, date, time, shot 
number, and ID1 to ID4.
Shutter speed
The time that the shutter is open. 
Slow shutter speeds give bright 
images, but motion resolution is 
lower.
SMPTE
Society of Motion Picture and 
Television Engineers, a professional 
association established in the U.S.A. 
mainly for the purpose of setting 
forth motion picture and television 
engineering standards.
Stand-by off mode
A mode in which the head drum is 
stationary and the tape is slack. It 
means that the VTR is not ready for 
immediate recording or playback. It 
does not mean that the tape or video 
heads are damaged.
Stand-by on mode
A mode in which the head drum 
rotates with the tape wrapped around 
it. It means that the VTR is ready for 
recording or playback. The VTR 
comes into Stand-by off mode in a 
settled time not to damage tape and 
video head.
Superimpose
A procedure you use to put one 
picture (or character) over another so 
that both can be seen at the same 
time.
Time code
A digital signal recorded on the 
videotape that supplies information 
such as the hour, minute, second and 
frame number of each frame. There 
are two kinds of recorded signal: 
longitudinal time code (LTC) and 
vertical interval time code (VITC).
Time code synchronization
To synchronize the built-in time code 
generator of video equipment to an 
external time code.
Time data
Time information that is generated by 
a time code generator or read by a 
time code reader.
User's bits
A 32-bit section of time code in 
which you can record desired 
information such as the year, month, 
date and reel numbers.
VBS
Abbreviation for video-burst-sync. A 
composite signal consisting of a 
video signal, a burst signal, and a 
sync signal.
VITC
Abbreviation for vertical interval 
time code. A time code recorded on 
tape with video signals and inserted 
in the vertical blanking interval of 
video signals.The VTR can read this 
time code even in still mode.
White balance
The adjustment of red, green and blue 
signal levels so that white objects are 
reproduced as true white.
White shading
A phenomenon whereby the upper 
and lower portions of the white object 
that you are shooting appear magenta 
or green, while the central portion of 
the image appears white.
Zebra pattern
Striped patterns that appear in the 
viewfinder to indicate areas of the 
picture where the video level is about 
70 IRE units or 490 mV.
Zoom
To gradually change the field of view 
of a camera lens from wide to narrow 
angle (zoom in) or narrow to wide 
angle (zoom out).
