OPERATOR'S SAFETY SUMMARY
CAUTION — these instructions are for use by qualified personnel only. To reduce
the risk of electric shock, do not perform this installation or any servicing unless you
are qualified to do so. Refer all servicing to qualified service personnel.
To ensure safety:
•
The unit should not be exposed to dripping or splashing, and no objects filled with liquids, such as
vases, shall be placed on the unit.
•
When the unit is to be permanently cabled, connect the protective ground conductor before making
any other connections.
•
Operate built-in units only when they are properly fitted into the system.
•
For permanently cabled units without built-in fuses, automatic switches, or similar protective facilities,
the AC supply line must be fitted with fuses rated to the units.
•
Before switching on the unit, ensure that the operating voltage set at the unit matches the line
voltage, if appropriate. If a different operating voltage is to be set, use a fuse with the appropriate
rating. Refer to the Installation Instructions.
•
Units of Protection Class I with an AC supply cable and plug that can be disconnected must be
operated only from a power socket with protective ground contact:
•
−
Do not use an extension cable—it can render the protective ground connection ineffective.
−
Do not intentionally interrupt the protective ground conductor.
−
Do not break the protective ground conductor inside or outside the unit or loosen the protective
ground connection; such actions can cause the unit to become electrically hazardous.
Before opening the unit, isolate it from the AC supply. Then ensure that:
−
Adjustments, part replacements, maintenance, and repairs are carried out by qualified personnel
only.
−
Safety regulations and rules are observed to prevent accidents.
−
Only original parts are used to replace parts relevant to safety (for example, the power on/off
switches, power transformers, and fuses).
•
Replaceable fuses can be hazardous when live. Before replacing a fuse, disconnect the AC power
source.
•
Use caution when cleaning the equipment; isopropyl alcohol or similar solvents can damage or
remove the labels.
•
Observe any additional safety instructions specified in this manual.

Configuring the VTM-420HD/SD Communications
Interface
The following subsections provide instructions to rack mount, connect, and configure
the unit.
Communication Ports
A VTM-420 HD/SD has three communication ports:
The VTM-420HD/SD has one Ethernet port and two serial ports:
•
The optional ETHERNET port is permanently configured for 10/100BaseT.
•
The RS-232 COMM port is factory-configured for RS-232 operation, but it can be
reconfigured for RS-422 multidrop operation. This is a software setup located in
the I/O and Communications menu. For multidrop operation, select RS-422
TERMINATED in the I/O AND COMMUNICATIONS/SERIAL PORT menu for
the last VTM-420 HD/SD using the RS-232 COMM port. For all other units in the
multidrop operation, select RS-422 UNTERMINATED.
To configure the unit:
1. Press the SETUP/LEARN button.
2. Use the WAVEFORM POSITION-H Knob (H Knob) to select the I/O AND
COMMUNICATIONS menu.

4. Use the H knob to select the serial port.
5. Press the H knob.
6. Use the H knob to select the format communications desired (RS-232,
RS-422 UNTERMINATED, or RS-422 TERMINATED).
7. Once selected, press the WAVEFORM POSITION-V knob three times to exit.
•
The REMOTE port is permanently configured for RS-422 operation. It can be
connected to one RCU-420 HD/SD remote control panel and looped to multiple
VTM-420 HD/SDs. For multiple configurations only, this port should be
terminated on the last VTM-420 HD/SD via an internal jumper, as shown in
Figure 2-1.
Figure 2-1. Terminating the Remote Port

Press INPUT next to the A and B LEDs to select A, B, or A+B. The default condition
for A+B is the PARADE mode. Inputs A+B are available in RGB and YCBCR formats
when both inputs are the same video standard.
NOTE: Enter the SETUP MENU to change to the OVERLAY mode.
Selecting Filters
There are three filters available: Flat, Low Pass, and Chroma/Bowtie. Press FILTER to
select the next filter. Multiple filters can function simultaneously (see Selecting
Multiple Inputs and Filters on page 3-15).
Selecting Sweep Modes
Press SWEEP to select one of the four sweep modes: 1H (1 Horizontal line), 2H
(2 Horizontal lines), 1V (1 Vertical field), and 2V (2 Vertical fields). Under the
DISPLAY SETUP menu, there are two settings for the VGA FRAME RATE that
affect the appearance of the waveform in vertical sweep modes: VESA 60 Hz and
OPTIMIZE FOR INPUT. Select VESA 60 Hz to keep the monitor output fixed at
60 Hz. This ensures that interruption of the input signal does not cause the monitor to
go blank. OPTIMIZE FOR INPUT locks the monitor very close to the input sweep
rate.
Selecting a Display Format
Press FORMAT to select one of three display formats: RGB, YCBCR, or COMPOSITE.
Table 3-7 lists the relationships between the input and display formats:

VIDEO SETUP.
3. Press the H knob.
4. Rotate the H knob to select WAVEFORM SETUP.
5. Press the H knob.
6. Rotate the H knob to select WAVEFORM OVERLAY.
7. Press the H knob.
8. Rotate the H knob to select OVERLAY.
9. Press the WAVEFORM POSITION-V knob four times to exit.
To display the INPUT A and B Y (luminance) channel PARADE:
1. Press INPUT until the A and B LEDs are illuminated.
2. Press FORMAT to select YCBCR.
3. Press EDIT/CLEAR until cell #1 indicates A(Y) and cell #2 indicates B(Y).
The default condition of digital inputs A + B is an overlay of YCBCR .
AUDIO, VECTOR, and WAVEFORM ZOOM Buttons
There are three ZOOM buttons: WAVEFORM, VECTOR, and AUDIO. The following
subsections explain the use of the buttons.
Expanding the Audio Display
•
To expand the audio scales around the 0 dB reference point and enable increased
resolution of readings, press AUDIO ZOOM.
•
To clear the peak-hold scale indicator, press and hold AUDIO ZOOM for
approximately two seconds.
VTM-420HD/SD Installation and Operation Handbook

Operation
Expanding the Vector Display
Press VECTOR ZOOM to select one of five expanded display options:
•
Expand the center
•
Expand the upper-left quadrant
•
Expand the upper-right quadrant
•
Expand the lower-right quadrant
•
Expand the lower-left quadrant
As with AUDIO ZOOM, the VECTOR ZOOM is helpful when an increased resolution
of phase or saturation readings is required.
Expanding the Waveform Display
Press WAVEFORM ZOOM to select one of two display options:
•
ZOOM positioned on the 0 IRE, 0 mV, or 0% graticule line
•
ZOOM positioned on the 100 IRE, 700 mV, or 100% graticule line
At each zoom position, the graticule scale and waveform displays expand to provide
more resolution around the zoom point.
Scrolling Through or Clearing the Alarm List
•
To scroll up or down the alarm list using the WAVEFORM POSITION-V knob,
press ALARM SCROLL/CLEAR.
•
To clear the alarm list, press and hold ALARM SCROLL/CLEAR for
approximately two seconds.
For more information on setting and reading alarms, see Setting Alarms on page 3-48.
Ethernet Interface (Option)
The VTM-420HD/SD Ethernet interface provides a high-speed communication link to
the Videotek SpyderWeb application over standard LAN and Internet networks. The
interface conforms to industry Ethernet standards:
•
Connection by a standard RJ45 socket
•
Automatic detection and switching between 10Base-T and 100Base-T
•
TCP/IP stack is fully compliant with RFC2500, “Internet Official Protocol
Standards”
•
Fully compliant with IEEE 802.3 Ethernet standard
The interface can accept a static IP Address, or it can obtain an IP Address dynamically
from a DHCP server. The IP Address, Subnet Mask, Gateway address, and DHCP
enable are all programmable from the I/O AND COMMUNICATIONS menu.
3-16
VTM-420HD/SD Installation and Operation Handbook
Operation
ROUTER CONTROL
There are two RJ11 router control ports located on the back panel. The ports are used
to control Videotek RS series routers. One RS series router can be connected to each
port. The router can be switched manually or set to scan all inputs, which is especially
useful when the alarms are activated. The router can be set to continuously scan
selected inputs searching for alarm conditions. All alarm conditions detected by the
VTM-420HD/SD will be logged on the display (maximum 100 alarms), or a PC
(running SpyderWeb software) can produce a continuous log file.
Router control is accessed in the SETUP menu under the VIDEO SETUP/VIDEO
GENERAL/INPUT A or B ROUTER menu. Selecting ROUTER will allow manual
control, and SCANNER will force the router to sequentially switch through all
activated inputs. DWELL TIME is used on each input for the selected time. Manual
control has two methods of operation:
•
Selecting INPUT A or B ROUTER in the VIDEO SETUP menu.
•
Pressing and holding the INPUT button while rotating the WAVEFORM
POSITION H knob (H knob), which cycles through all the enabled router channels.
This function is disabled when in the SETUP menu.
Each input (INPUT A1 to INPUT A12/INPUT B1 to INPUT B12) of the router can
also be given a unique name that will be placed in the log file when an alarm is
detected on that input. The names are entered using a keyboard connected to the back
panel.
EXTERNAL GPI
The INPUT and OUTPUT General Purpose Interface (GPI) has nine input GPI and two
output GPI connections. The pin-out and default functions are listed in Table C-4 on
page C-4 in Appendix C.
INPUT GPI
The input GPIs have two selectable functions. The first function allows external
control of the unit using the default settings. The second function of the GPI shows an
onscreen alarm with a user-selected identification from an external input.
To setup GPI for USER FUNCTION:
1. Press SETUP/LEARN to display the SETUP MENU.
2. Rotate the WAVEFORM POSITION-H knob (H knob) to move the cursor to I/O
AND COMMUNICATIONS.
3. Press the H knob.
4. Rotate the H knob to move the cursor to GPI INPUT FUNCTION.
5. Press the H knob.
6. Rotate the H knob to select the desired input.
7. Press the H knob.
8. Rotate the H knob to select USER GPI.
VTM-420HD/SD Installation and Operation Handbook
3-17
Operation
9. Press the H knob.
10. Use the keyboard to insert a new name.
11. Press the WAVEFORM POSITION-V knob five times to exit.
OUTPUT GPI
There are two OUTPUT GPIs with a list of 37 GPI alarm activations to choose from.
All GPI alarm activation selections are set to the default OFF. When a selection is set
to ON it allows the GPI to function according to the GPI Output Polarity Setting
(NORMALLY OPEN, NORMALLY CLOSED). The default polarity setting is
NORMALLY OPEN. These settings are found in the I/O AND COMMUNICATIONS
menu.
LTC/CLOCK
There are inputs for an external Longitudinal Time Code (LTC) and Clock (CLK) on
the GPI/TALLY, LTC/CLK connection listed in Table C-4 on page C-4 in
Appendix C. The LTC/CLK shows when and how long an error occurs. When an
error develops, the captured time of that error from the internal clock is expressed with
the specific alarm in the lower-left corner of the screen. The Time Code selection and
the Clock can be set in the I/O AND COMMUNICATIONS menu.

CLOSED CAPTION DISPLAY
The closed caption display monitors both Standard Definition and High Definition
formats. Standard Definition formats, primary caption service (CC1) or secondary
caption service (CC3), which are defined by the EIA-608-B NTSC Line 21 Closed
Caption standard, can be selected. For High Definition formats, only NTSC Line 21
captions EIA-608B, CC1 or CC3 captions can be selected. Other Digital Television
Closed Caption services, as defined in EIA-708-B, are not decoded. These settings are
found in the VIDEO SETUP menu. The H knob scrolls through the Closed Caption
selections. The default caption service for both High and Standard Definition is CC1.
The CLOSED CAPTION SIZE field selection determines if the text in the closed
caption display is large (covers more of the displayed video signal) or small (covers
less of the displayed video signal).

Configuring the Optional Audio Display
The VTM-420HD/SD is capable of displaying many audio standards. To take
advantage of this flexibility, use the SETUP MENU to select specifications unique to a
studio environment.
The following discussion is useful for determining specific setup requirements.
The AUDIO SETUP menu is detailed in Table 3-10.
There are eight analog audio input channels (four stereo pairs), 16 AES/EBU digital
input channels (eight stereo pairs), and 16 embedded audio channels (serial-digital
video input only) available for selection in the menu. Up to eight channels display
simultaneously and show a vertical display or a CineSound display. Analog,
AES/EBU, and embedded audio inputs can be assigned to track video input A or B.
The displayed audio can be monitored as analog signals on the 37-pin, ANALOG
AUDIO IN/OUT connector. If the display is AES/EBU or embedded audio, the
monitoring output is analog audio. The output audio level can be adjusted ±6 dB. This
adjustment is on the AUDIO SETUP menu. Audio input pairs can be assigned to any
meter pair on the display.
Adjustable markers can be placed in the audio meters to show a specific critical level.
In addition, alarms can be activated to monitor peak levels, phase differences, loss of
3-42
VTM-420HD/SD Installation and Operation Handbook
Operation
sound, and loss of data. The adjustable markers are selected in the AUDIO
SETUP\AUDIO MARKERS menu.
The unique CineSound display monitors 5.1 or 7.1 channels of surround sound. The
CineSound input mapping follows a SMPTE 320M standard.
The phase bars monitor the instantaneous phase relationship between two audio
channels. The “+” marking indicates a phase difference of 0 degrees, and the “-”
marking indicates a phase difference of 180 degrees. A properly phased stereo pair
produces a phase pointer (yellow mark) that moves within the green zone, whereas a
reversed channel produces a pointer that moves within the red zone.
For example, to set four channels of analog audio to follow input A:
1. Press SETUP/LEARN.
2. Rotate the WAVEFORM POSITION-H knob (H knob) to highlight the AUDIO
SETUP menu
3. Press the H knob.
4. Rotate the H knob to highlight CONFIGURE INPUTS.
5. Press the H knob.
6. Rotate the H knob to highlight INPUT A.
7. Press the H knob.
8. Rotate the H knob to highlight AUDIO TYPE.
9. Press the H knob.
10. Rotate the H knob to highlight ANALOG.
11. Press the WAVEFORM POSITION-V knob (V knob) to exit one level.
12. Rotate the H knob to highlight AUDIO DISPLAY.
13. Press the H knob.
14. Rotate the H knob to highlight 4 CHANNELS.
15. Press the H knob.
16. Rotate the H knob to highlight METER 1.
17. Press the H knob to select it.
18. Rotate the H knob to select INPUT PAIR and press the knob to select it.
19. Rotate the H knob to highlight PAIR 1.
20. Press the V knob two times to exit two levels.
21. Rotate the H knob to highlight METER 2.
22. Press the H knob.
23. Rotate the H knob to select INPUT PAIR.
24. Press the H knob.

Dolby Selections
Option 8 includes Dolby Digital and Dolby E technology selections. These selections
are found in the Audio Setup menu on page 3-24.
Six or Eight channels of Dolby E can be selected from the Audio Setup menu. Within
each channel is a list of encoded selections. The encoded channel selections can be
broken down into:
•
5.1: The “5” consists of three front channels (left, center, and right), and two
surround sound channels (right surround, left surround). The “.1” provides the
bass.
•
4: Four speaker configuration consisting of two front speakers and two surround
sound speakers. Usually used to simulate sound coming from a phantom center
speaker.
•
2: Stereo channels
•
1: Mono channel
With the channels defined, an example of an 8-channel configuration shown in the
Audio Setup menu is “8x1.” This example signifies that eight channels will receive a
mono signal.
Some of the other Option 8 terminology found in the Audio Setup menu are:
•
Low Frequency Effects (LFE): provides a deep base effect.
•
Dolby AC-3: Audio coding for multiple or single channel transmission.
•
Dolby Digital: Digital audio format using Dolby AC-3.
•
5.1: Surround Sound Configuration. The “5” consists of three front channels (left,
center, and right), and two surround sound channels (right surround, left surround).
The “.1” provides the bass.
•
Lt and Rt: Left total and right total channels for surround sound setup.
•
Lo and Ro: Left only and right only sound channels for stereo use.
•
L: Left channel
•
C: Center channel
•
R: Right channel
•
Ls: Left surround channel
•
Rs: Right surround channel
•
L+C: Left and center channels
•
L+R: Left and right channels
•
#/#: The number of front speakers to the number of surround sound speakers

CAPTURE ON ALARM
The VTM-420HD/SD provides a feature that creates a frame capture when one or more
user-selectable VTM-420HD/SD alarms are triggered. When used with SpyderWeb,
this feature automatically transfers and stores the frame capture to a PC. After the
frame capture is sent to a PC, SpyderWeb manages the frame capture by indicating that
the triggered alarm has a frame capture. SpyderWeb then links the alarm to the frame
capture file that is saved on the PC. When the alarm is selected in SpyderWeb, the
frame capture can be viewed or deleted. See the SpyderWeb online help for more
information.
From the VTM-420HD/SD, the frame capture is immediately displayed if the
RETURN TO ACTIVE PIC menu item in the CAPTURE SETUP submenu is set to
MANUAL.
If RETURN TO ACTIVE PIC is set to AUTO, the active picture replaces the frame
capture. In this case, the captured frame can only be viewed if CAPTURE DISPLAY is
set to HOLD IN DISPLAY CYCLE, as described in Capturing and Transferring the
Entire XVGA Display, on page 3-46. If HOLD IN DISPLAY CYCLE is set, press the
DISPLAY button on the front panel to view the frame capture.
To enable or disable the VTM-420HD/SD alarm capture feature:

Setting Alarms
Most alarms monitor all lines of the video signal instead of just a single line. For
example, the GAMUT alarm monitors the entire active picture for errors over the
preset limits chosen on the menu.
Limits are selected by choosing a value using the WAVEFORM POSITION-H or
WAVEFORM POSITION-V knobs, while additionally causing a limit cursor line to
appear in the waveform or vector display. Do not confuse these limit cursor lines with
the cursor lines selected on the VIDEO SETUP menu. The limit cursor lines disappear
when exiting the alarm menu.

VTM-420HD/SD Installation and Operation Handbook
Operation
Sensitivity and Duration are two general terms used in the alarm menus:
•
Sensitivity
Sensitivity is set in Consecutive Errored Samples (CES). When setting amplitude
limits, a noise spike can exceed the limit while the video amplitude can be within
the limit. With the CES set to a low number, a spike is detected and an alarm is
displayed. Set the CES to a higher number to ignore the fast spike. Each CES
occurs at an approximate pixel rate. Use this as a guideline to select the appropriate
CES value.
Not all alarms have CES associated with them; in such cases, use the duration to
increase or decrease the general sensitivity.
•
Duration
This value, from 0–60 seconds, determines how long an error must persist before it
is reported. Set the duration to 0 to display an error as soon as the CES value is
met.

Alarm or error name
When an error is first registered, it appears at the bottom of the error display and is
highlighted in yellow. If the error is short term (i.e., two seconds or less), the error text
reverts to the original graticule color after approximately two seconds. If the error
continues longer than two seconds, the text remains highlighted in yellow and the error
duration is incremented. When the next error occurs, the previous error moves up one
position.
When 100 different error events occur, error number 01 is dropped and the most recent
error is tagged as 100. There is a maximum of 100 error events that can be stored. To
overcome the 100-event limit, connect a PC to the RS-232 COMM or Ethernet port and
use the SpyderWeb software included; all errors are passed to the PC and saved.

Operation
Press ALARM SCROLL/CLEAR to scroll, or press and hold the ALARM
SCROLL/CLEAR button to erase the current group of 100 errors. A GPI output
dry-contact closure can be used to alert other devices when an error occurs. Use the
I/O AND COMMUNICATIONS menu to setup GPI.
An alarm can also trigger a screen capture. The CAPTURE SETUP menu is in the VIDEO
SETUP menu. To capture and store a complete screen when an alarm occurs, set the
Capture Trigger mode to Alarm. If the screen capture is saved to a PC, the transfer can
take up to a few minutes depending on if the transfer is being run over an RS-232 or
Ethernet connection. While other alarms can occur during this transfer, the feature is
helpful when unattended monitoring is required.

(RCU-420HD/SD)
The RCU-420HD/SD remote control unit enables remote control of as many as 30
VTM-420HD/SD units.
Installing the RCU-420HD/SD

Description
1
TO MAIN UNIT
9-pin, male, D-sub connector connects to the REMOTE connector on the
VTM-420HD/SD to provide RS-422 communication. The communication
parameters are 8 data bits, no parity, with the baud rate fixed at 38,400 bps.
2
5V DC IN
Connects to the DC power plug on the RCU-420HD/SD DC power supply. A
knurled ring enables the power plug to be secured to the jack after the plug is fully
inserted. This connection must be made before AC power is supplied.
To install the RCU-420HD/SD:
1. Connect the DC power supply to the 5V DC IN connector.
2. Connect the power cord to a properly grounded AC outlet.
3. Verify that the INPUT and REF LEDs flash in alternate pairs (A+EXT and
B+INT); if they do not, check steps 1 and 2.
4. If multiple VTM-420HD/SD units are being connected, ensure each has a unique
unit ID (from 1-32) before connecting them to the RS-422 bus. If a
VTM-420HD/SD has a unique ID other than 1.
NOTE: If a VTM-420HD/SD does not have a unique unit ID, change it on the I/O AND
COMMUNICATIONS submenu.
a) Physically connect the RCU-420HD/SD to a bus with multiple
VTM-420HD/SD.
VTM-420HD/SD Installation and Operation Handbook
D-1
Remote Control Unit (RCU-420)
b) To select the VTM-420HD/SD to be controlled by the RCU-420HD/SD, press
SETUP/LEARN and LINE SELECT on the RCU-420HD/SD simultaneously
(the VTM-420HD/SD selection mode is restricted to the RCU-420HD/SD).
While in the selection mode, the LINE SELECT ODD and EVEN LEDs
alternately flash.
c) Rotate the LINE SELECT knob until the Unit ID on the VTM-420HD/SD to be
controlled turns green.
d) Simultaneously press SETUP/LEARN and LINE SELECT to end the selection
process. When communication is established between RCU-420HD/SD and
the VTM-420HD/SD, the RCU-420HD/SD LEDs will stop flashing in
alternate pairs. The RCU-420HD/SD LEDs now reflect the settings of the
VTM-420HD/SD and RCU-420HD/SD front panel operations affect the
VTM-420HD/SD. To indicate connection to the RCU-420HD/SD, the
selected VTM-420HD/SD changes the background for the UNIT ID on the
XVGA display from red to green (see Figure 3-1 and Table 3-1).
e) The RCU-420HD/SD polls the selected base unit every 100 ms. If the
VTM-420HD/SD fails to receive the poll, it assumes that there is a
communication break.
A communication break is indicated by changing the background for the
UNIT ID on the XVGA display from green to red and alternately flashing the
A+EXT and B+INT LEDs on the RCU-420HD/SD. When communication is
re-established, the INPUT LEDs stop flashing.
5. If multiple VTM-420HD/SDs are configured, the RCU-420HD/SD must be at one
end of the RS-422 bus. The last VTM-420HD/SD must be terminated at the other
end by using a jumper, as shown in Section 2 by Figure 2-1 for the

Encoded Clip Softness In the encoded legalization process, “softness,” as applied
to encoded clips, refers to the processing of the video at the point of the clip. The clips
are applied in YCBCR color space. The clip point is either an immediate limit (no
softness) or will have a range of values leading to the clip point, all reduced to smooth
the clip point to a less immediate limit (softness).
Encoded Legalization Limiting of the luminance and color difference signals such
that, once encoded into a composite video signal, the resultant encoded video does not
violate the maximum or minimum signal levels as defined by the specific encoding
rules. NTSC and PAL video plus various users of these types of video have many
varied rules for maximum and minimum encoding limits. Encoded legalization usually
calculates first the encoded luminance value and then the corresponding chroma value
to make legalization judgements.
Encoded Video A combined single video signal that is constructed from either
separate RGB or luminance and two color difference video signals. NTSC, PAL, and
SECAM are all examples of encoded video.
Envelope Detection An RF signal detection technique that does not respond to
phase variations in the carrier signal, enabling measurement of a transmitter’s
incidental phase. When used together with synchronous detection, envelope detection
helps isolate either video and/or RF as the causes of phase distortion.
External Key Input This is an alternate source for key cut. This is usually a separate
external input to a switcher
Fade-thru-Black A production technique which is a two step process. The first step
will fade the program video to black. The second step will fade from black to the video
selected on the preview bus. This is usually used in major scene transitions.
Fade-to-Black A production technique which simply fades the program video to
black and program audio to silent. This is used to end programs and to escape from
embarrassing pictures or sounds.
Field A picture or picture portion which is produced within one cycle of vertical
synchronization. In interlaced systems, a full picture or frame requires two consecutive
fields.
FM Trap A circuit designed to minimize potential interference from strong FM signals
in receiving equipment, such as a TV demodulator. For example, an FM trap can
attenuate signals between 88-108 MHz to reduce interference on NTSC television
channel 6.
Frame A single full resolution picture as viewed in either a video or film system. In
the case of interlaced video, two consecutive fields provide all of the information of
one frame. In non-interlaced systems, one cycle of vertical synchronization produces a
frame. A 60 Hz interlaced system, produces 30 frames of video in one second. A 60 Hz
progressive (or non-interlaced) system, produces 60 frames of video in one second.
Common frame rates are 24 (film) 25, 29.97, 30, 50, 59.94 and 60.
