Getting Acquainted with the Opera Chassis
All inputs not intended to be used with the internal frame syncs, must be genlocked to the
same system timing as the switcher. Input timing has a +/- 18 microsecond timing window,
so additional timing adjustments are not necessary.
All inputs may be mapped to any panel crosspoint using the configuration file. In addition
to external inputs, Opera has two color matte generators, one frame buffer, and two alpha
frame buffers (for organic wipes) that may be accessed by crosspoint.
System on Chip Technology
The most important development of the Echolab Opera Series of Dual - Format Video
Production Switchers is that it is virtually a complete 'system on a chip' solution. The
compact switcher's engine is a single Xilinx Virtex-II Pro chip which is feature-driven
through Echolab proprietary firmware. The innovative chassis is 6RU with a rack depth of a
mere 7.2 inches; weighing in at under 6 pounds! It is perfect for small studios, ideal for OB
Vans and highly portable for almost any type of production environment from control rooms
to classrooms. Single chip architecture also means low power consumption, extremely
quiet operation, far fewer points of failure due to the massive reduction in overall required
parts, and no added thermal intrusion to your rack.
Opera Input and Output Chassis Layout
Tally
Thirty-two mappable contact closure tallies in
four banks of eight. The common on any bank
can accept either ground or external voltage for
flexibility of installation.
GPIO
Three general-purpose input and two general
purpose output triggers can be easily assigned
for an array of switcher functions.
Memory card
The compact flash memory contains the user
configuration file and allows internal storage for
100's of stills and organic wipes. Allows for
graphic and macro storage and retrieval
independent of network.
Status Lights
Status lights provide reliable monitoring of
genlock, processor and disc activity.

Installation
Orientation
The Opera Chassis is designed to set on a flat, non-conductive, surface or to be rack
mounted. The panel is designed to set on a flat surface, but may be table mounted.
Power
The power supplies for the chassis and panel are auto sensing between 100 and 240 volts
AC. Conditioned, un-interruptible power is recommended.
Memory Card
Opera is supplied with two compact flash memory cards. The cards are loaded with the
latest software. A Memory card is necessary to properly initialize the switcher on start up.
The memory card also contains the user configuration file, stills, and organic wipes. Once
the system is initialized, the card may be removed, but access will be lost to wipes and
stills that are not already loaded to the panel memory.
Figure 5.5 Memory Card Slot / Compact Flash card
System timing
Opera requires a continuous SDI signal connected to “Genlock” on the chassis. The
switcher will not operate without a genlock signal. Black is recommended.
Input Configuration
The Opera comes with 2 types of Input modules; Analog or SDI. The analog inputs each
need to be configured for which type of analog format is to be used. There is the additional
setting for using the internal Frame Sync for that input. The SDI inputs only need to be set
for using the internal Frame Sync.
Configuring Analog Inputs
Using the LCD buttons, from the Home menu select I/O to go to the Input and Output
selection menu.
Select INPUT Format. Select the crosspoint for an external analog source on Preview.
Select an analog format from the options displayed on the LCD button menu:
CMP – Composite
YC – Y/C, SVHS
YUV – Component YCbCr
RGB – Component RGsB
Select FRAME SYNC to turn on the internal frame sync for this source. Using the internal
Fram Sync allows for the use of asynchronous sources. The Frame Sync will add up to 1
frame of delay to the source.
Configuring SDI Inputs
Using the LCD buttons, from the Home menu select I/O to go to the Input and Output
selection menu.
Select INPUT Format. Select the crosspoint for an external SDI source on Preview.
SDI is the only format choice and will be shown as the default selection.
Select FRAME SYNC to turn on the internal frame sync for this source. Using the internal
Fram Sync allows for the use of asynchronous sources. The Frame Sync will add up to 1
frame of delay to the source.
Saving Input Formats
When in the Input selection menu, one of the soft keys is assigned for save. Pushing save
will write the configuration file to the Compact Flash. The Inputs will maintain their
configuration even after losing power to the chassis.
NOTE: Saving from the Input selection menu also saves the analog configuration of the
outputs. You want to configure your outputs, and then return to this menu to save.
Mode Switch
The Mode switch allows for loading different sets of User Configurations, or Modes, at start
up of the switcher. To change configurations, dial up the number of the Mode desired and
power up the chassis.
Modes can be changed without turning off the panel.
Serial Port
The serial port is a standard female DB-9 connector. It supports EIA RS-232.
Edit Port
The serial port is a standard female DB-9 connector pinned as a SMPTE slave. It supports
EIA RS-422.
Ethernet
The Ethernet connection is T-base 10/100 and can be configured for your network, or to
create a network, using the Configuration file (See Operations: User Configurations).
GPIO
GPIs 1 through 4 as well as GPO 1,2 and 3 are brought out on this connector (Figure 3).
The GPI inputs can be triggered by either a short to ground or a trigger from a TTL or
bipolar level signal (+/- 12v max). GPOs are programmable to be pulses or a user-defined
trigger length. GPIO is programmed using the User configuration file. (See Operations:
User Configurations)

GPO 2
GPI 1,2,3
Figure 3. GPIO connectionsTally
There are 32 tallies available for your switcher. The tally connections function by providing
an open collector output that provides a short to ground when selected (1/2 amp, 30V
max.). Tally output pins are mappable using the User Configuration File. See the Section
on Changing Switcher Configuration for information on Tally mapping.

Figure 4. Tally connections
Panel Connection
The chassis and panel are connected using two 75-ohm coax cables (not supplied)
connected to the RX (receive) and TX (transmit) connectors; RX connects to TX, and TX to
RX. The maximum separation is 300 meters.
Figure 5.10 Panel connection jacks
Startup
Initializing System
Power up the Opera Chassis and Overture 1 control panel. Make sure the SDI genlock
source is connected to the chassis and the memory card is in the reader.
Status Lights
During initialization the green status light should blink and then go out. The red status light
blinks if the memory card is not in the reader or not properly formatted and loaded.
System Lights
After initialization, all four system lights on the chassis (Figure 5) should be on:
Main diagnostic Lighted when the system is running.
Disk activity Lighted when data is being read from or to the memory card.
CPU activity Flashes whenever the system is running (like a heartbeat).
Genlock indicator Lighted when a genlock source is present. The system will not operate
properly without a genlock source.

Verifying Successful Startup
If the panel does not initiate to it’s Home configuration, check for proper genlock, secure
panel connection cables and a properly inserted memory card. The Status Lights on the
chassis will help.
The LED strip above the Program bus should show Input names and positions as they are
designated in the User Configuration file. See the section on Changing Switcher
Configuration for more information.
Menus
The LCD buttons menu buttons are available on the M/E bank of your Overture 1 panel.
This control area lends access to the various Menus used to operate the switcher.
The Display, Rotary Encoders, and Soft Keys all work in conjunction with the Menus. The
Display will show the assignments for the Rotary Encoders and Soft Keys as determined
by which Menu is selected.
The Home Menu has buttons to navigate to the designated menus for control of the
following functions / features of the switcher:
TAKE PATT – Menus for assigning the wipe patterns for transitions.
DVE PATT-Menus for assigning DVE Transitions as well as Graphic wipes and Stinger
Key.
EFF KEYS – Menus for controlling the upstream keyers.
DSK KEYS – Menus for controlling the 2 downstream keyers.
FBUF – Menus for controlling the internal Frame Buffer(s).
I/O – Menus for settings network addresses for the switcher and integrated products.
RATES – Menus for setting the auto transition rates for Take, and all keyers and move
rates for the DVEs.
COLOR - Menus for controlling the 2 internal Color Matte Generators.
AUX – Menus for assigning the Auxiliary outputs.
Super Source-Menu for setting up and prioritizing your super source elements.
Transitions
Switching from one video source to another is the primary function of a video switcher.
The functional block that performs this operation is the mix/effect block (M/E). The M/E
accepts two video inputs and makes a single output (Figure 7).
Normally, the program input is passed directly through to become program out. During a
transition, program out is a combination of program input and preview input, eventually
becoming entirely preview (Figure 8).
Program In
Program Out
Preview In
Figure 7 Mix/Effect block
Figure 8 Transition example
At the end of a transition, the sources applied to the program and preview inputs change
places to return to the initial state of passing program input directly through the block
(Figure 9). To indicate this flip-flop, the highlighted buttons on the program and preview
buses of the panel are exchanged.
If you complete a transition by moving the fader bar down, you initiate the next transition by
moving the fader bar up. The direction will generally alternate between up and down after
each transition. The fader bar indicator (Figure 1 on page 13) next to the fader bar
displays the position and progress of the current transition.
Figure 9 Source flip-flop after a transition
Transition Types
The mix/effect block (M/E) performs three types of transitions:
Cut: Switch immediately to the preview source.
Mix: Gradually fade from program to preview. Output is a linear combination of program
and preview.
Wipe: Use a moving borderline to reveal the preview and cover the old program.
Dip: Uses the border source as the middle of the transition. Program video→Dip Through
(border source)→Preview Source as the transition completes.
DVE: Uses spins, swooshes, pushes, stinger and graphic wipes to perform transition.
At the completion of a transition, the operator composes the next video scene on the
preview input, then switches the scene to program at the desired time by using one of the
transition types.
The program and preview inputs are fed by a background video source and sometimes a
combination of the effects keys layered on top of the background video.
The operator continuously executes the cycle in Figure 10 to produce a show:
•
Start with program out
•
Specify modifications to the background video and keys
•
Examine the result on preview
•
Transition preview to program.

Next Transition
The modifications to the current program output are controlled using the Next Transition
Control buttons. The operator can change the background video or any of the effects
keyers and include them in the next transition by pressing the desired button.
If the background is involved in the next transition, the background video on the preview
bus is selected using the preview bus buttons on the panel. If the background is not
involved in the next transition, the background video is the same as the program.
The effects keyers layer the key cut and fill sources over both program and preview
sources independently. The small button above the key next transition buttons displays
the state of the keyer on the program side of the me. If the button is lit, the keyer is active
on the program side, and should be visible on program out.
If a key is involved in the next transition, the state of the keyer over preview will be the
opposite of what it is over program:
•
If the keyer is currently on, it will be turned off over preview.
•
If the keyer is currently off, it will be turned on over preview.
If a key is not involved in the next transition, the state of the keyer over preview will be the
same as it is over program. Keyers that are on stay on, and those that are off remain off.
To include the background and keys or multiple keys in the next transition, the selected
buttons must be pressed and released simultaneously as a group.
A key can be directly cut between program and preview by pressing the small key status
button at the top of the Next Transition group.
Transition Examples
The following examples show basic elements you will use repeatedly to produce shows
with your Overture switcher. It illustrates the operation of the switcher with a few simple
sources:
•
A background video source of a weatherman at a desk
•
A background video source of an outdoor scene
•
Key1 is a lower third graphic with the weatherman’s name
•
Key2 is a graphic with today’s record high temperature
Initially, both keys are off and the weatherman is on program out (Figure 11). To transition
to the outdoor scene, press the BKGD button, specifying that we intend to change the
background video. The next scene appears on the preview monitor.
Executing a transition switches the outdoor scene to program.

The background on the preview side of the M/E is now supplied with a copy of the same
source that is visible on program because we specified that we do not want the
background involved in the next transition.
Key2 is turned on over preview, showing the desired result of the next transition.

Next, we will return to the weatherman with his name keyed over the lower third of the
screen.
Doing this requires three changes to the current program output:
•
Change the background to the weatherman
•
Turn on key 1
•
Turn off key 2
To indicate the changes in the next transition, simultaneously press the BKGD, KEY1 and
KEY2 buttons (Figure 13). All three buttons are illuminated. Notice that the small button
above Key 2 is illuminated, showing that Key2 is visible on program out.

As the last step in the example, we will remove the weatherman’s name several seconds
after we have brought him to program out. To accomplish this, we need only involve key 1
in the next transition. The small button above the KEY1 button is illuminated (Figure 14),
indicating that it is currently visible on program out. Key 1 is now turned off over preview,
showing us how our final configuration will look.
This final transition returns us to where we started the example: the weatherman with no
keys.

Setting Up a Transition
The operator chooses the type of transition and how to control its progress.
Cut
To execute a cut, press the Cut button. Program and preview are immediately exchanged.
Mix
To execute a mix, ensure that the Mix button is illuminated, or press it to select mix. The
progress of the mix can be controlled either manually or automatically.
Wipe
Wipes require the selection of several additional parameters that control the appearance of
the wipe.
To execute a wipe, ensure that the Wipe button is illuminated or press it to select wipe.
Next, choose shape of the wipe pattern on the Take Patterns menu page.
Pressing the Wipe button displays a menu of wipe patterns on the LCD buttons (see Figure
1 on page 13). You can also navigate to the Take Patterns menu manually.
The currently selected wipe pattern is highlighted in red.
Two types of wipe patterns are available on the Take Patterns menu: classic patterns and
organic wipes. These patterns are described in the following sections.
Classic Wipe Patterns
Classic wipe patterns include circles, squares, crosses, diamonds, horizontal and vertical
bars. To select a wipe, press the button with the shape that you want to use for the next
transition.
The aspect ratio and center of some classic wipes can be adjusted. If the wipe is
positionable, the joystick can move the center of the pattern horizontally and vertically
around the screen.
The aspect ratio can be adjusted using the Symmetry Knob or the Z axis of the Joystick.
Adjusting the Symmetry will allow you to change circle and square wipes into ellipses and
rectangles.
Organic Wipes
Organic wipes are controlled by the contours of a grayscale wipe image. The possible
effects are complex matrix wipes, multiple rotary wipes and free flowing shapes. The
control images for the 100 standard wipes are included in an appendix on page 95.
An organic wipe is selected by entering the number of the desired pattern on the numeric
keypad, then pressing the Organic button on the menu page. The light flashes briefly as
the image is read from the Opera memory card.
If an organic wipe is already selected, pressing the Organic button displays the number of
the current pattern in the upper right corner of the display.
Borders
The appearance of the border between the Program and Preview is controlled by the
rotary encoders (Figure 1 on page 13) when the Take Pattern menu is displayed.
The edges of the wipe pattern can be adjusted between sharp and fuzzy using the
softness rotary encoder.
The width of the border is adjusted with the Border rotary encoder.
If the border width is not zero, then some portion of the border source is visible. When the
Take Patten menu is displayed, the select bus allows you to select a video source to
display in the wipe border. One of the colors is frequently chosen as the source, but there
is no restriction on the source selection.
Dip
Dip through utilizes the selected transition block border source as the center of the
transition. The program output will “dip through” the border source on it’s way to the
preview source at the assigned transition rate.
DVE Transition
DVE transitions allow you to predetermine a DVE effect to use as a transition. Graphic
wipes as well as Stinger Keys are also available for these transitions.
Wipe Direction
Wipe patterns have a normal direction by convention. The normal direction for closed
patterns such as circles, diamonds and boxes is to grow from the center of the screen and
progress outward. When a wipe is reversed, closed patterns close in from the edges of the
screen toward the center.
The current status of the wipe direction appears on the soft keys when the Take Patterns
menu is displayed. If the toggle button is selected, the wipe pattern will alternate between
normal and reverse. The normal or reverse button is illuminated to indicate the direction of
the next wipe.
Controlling Transitions
To mix automatically at a smooth rate, press the Auto button in the transition control block .
The time required to complete the transition appears above the button. The duration of the
transition can be adjusted as described in the manual section on Adjusting Transition
Rates.
To control the mix manually, move the fader bar from one end of travel to the opposite end.
Pressing the Auto button while an auto transition is in progress stops the transition.
Pressing the Auto button again resumes the transition.
If you stop a manual transition before the end stop, pressing the Auto button will complete
the transition. The fader bar indicator turns off, signaling that the fader bar has been
disconnected from the transition. Moving the fader bar has no effect on transitions until the
fader bar and the transition are synchronized at an end stop.
To reconnect the fader bar, move it to one stop or the other. The last segment of the fader
bar indicator lights at the end of travel.
Transition Preview
The preview output shows what will appear on program at the end of the next transition.
Transition preview is used to see what your program will look like during the transition.
To preview a transition, press the Transition Preview button . The button lights and the
preview output switches to a copy of program out. Moving the fader bar performs the next
transition on the preview output. (You cannot preview a transition that is already in
progress.)
During the transition preview, you can switch between transition types or change wipe
parameters.
You can push the fader bar all the way to the end of the transition.
To end transition preview, return the fader bar to the end stop from which you started. At
the end stop, the light in the Transition Preview button will go out and the preview monitor
will return to normal operation. You are now ready to execute the transition.
Preview transitions can only be controlled with the fader bar. The Auto button is disabled
in transition preview.
Keying
Keyers create a layered video output by combining three input signals:
•
Fill video source
•
Key signal
•
Background video source
The key signal defines an area of the fill video that will be inserted into the background
video (Figure 15). The inverse of the key signal is used to cut a hole in the background
video. The switcher then adds the two pieces together, inserting the fill into the hole that
has been created in the background. Visually, it appears that the fill source has been “cut
into” or “layered over” the background image.
The Overture 1 gives you many powerful ways to use keyers in your production. This
section will show you how to set up each kind of key.
There are two things that must be done to set up a keyer:
1
Choose the fill video
2
Generate the key signal
The method of generating and adjusting the key signal is what distinguishes the different
types if keys.
Fill
Video
Key
Signal
Keyer

Video
Figure 15. Keying signal flow
The output of a keyer may become the background source of another keyer. This creates
multiple layers of effects. When keyers are arranged in series, the last keyer in the chain
has the highest priority. Its fill source will be the top-most layer of the resulting image.
The initial step to setting up a key is to set which key type is desired. These selections are
made using the EFF KEYS or DSK KEYS menus.
For the Effects Keyers, the options are:
LUMA KEY – luminence
CK KEY – chromakey
PATT KEY – pattern key
DVE – DVE key
Setting Up a Luminance Key
In a luminance key, the key signal is generated by processing the luminance channel of a
cut source video signal (Figure 16). The cut signal may be selected from any source that
is available in the crosspoint array. An external character generator will typically produce
cut and fill video signal, which will be connected to the external inputs of the switcher.

Luminance Key Adjustments
Clip and Gain
The two adjustments of a luminance key are the clip and gain.
The clip level sets a threshold that defines the size of the key signal. If the clip is set to
zero, the key will be clipped all the way in. With the clip set to 999, the key will probably
not be visible. Adjust the clip level until the key hole is the desired size.
The gain adjustment determines the softness of the key edge.
Reverse
The reverse key inverts the key signal. The cut and fill regions of the video swap when
reverse is selected.
Shaped
Most character generators produce shaped keys. The cut source has already been
carefully produced, to allow soft edges, drop shadows and transparency effects. The fill
source exactly matches the cut source, and neither should be modified by keyer
adjustments. Selecting Shaped applies the cut signal directly to the background and then
adds in the already shaped fill source. When Shaped is selected, the clip and gain
adjustments are removed.
Setting Up a Chromakey
A chromakey selectively replaces a color in the fill source with the background video. The
most common example of a chromakey is a computer-generated weather map behind a
weatherman. The weatherman stands in front of a carefully painted and lit wall that is
typically bright blue or green. The chromakey electronically searches for this color,
removes it from the fill source, and generates a key signal that displays the background
source in the areas where the color has been removed (Figure 17).

Select the Cut and Fill Source
The cut and fill sources are selected using the select bus of the panel. To set up a keyer,
navigate to the desired key menu using the LCD buttons Adding a keyer to the next
transition will automatically navigate to the key menu for the selected keyer. Verify that the
display above the select bus shows the name of the keyer you are setting up. Select CK
KEY as the key type on the Keyer menu.
You must select the source with the specially prepared chromakey backdrop as the fill
source. Since the key signal is automatically generated from the fill source, the cut source
is ignored.
Chromakey Adjustments
Hue
The hue adjustment selects the color that will be replaced. Rotate the hue knob until the
background keys through the desired color.
Gain
The gain adjustment determines how the colors around the select hue are keyed. Adjust
the gain knob until the edges of the keyed region appear the way you want them.
Ys - Luminance Suppression
The luminance suppression adjustment sets the black level of the region where the
chromakey level has been removed. Adjust the luminance suppression knob until the
black level of the chroma removed region is correct.
Lift
Key lift should normally be set to zero for a well set up chromakey scene. Key lift allows
very low saturation values of the keyed color to be excluded from key. Colored light
spilling onto a neutral colored object in the foreground will sometimes cause small areas to
key to the background source. Key lift allows you to fill these small holes in the key signal.
Narrow
The acceptance angle of colors around the selected hue should generally be as broad as
possible to achieve natural looking chromakeys. Sometimes, if some colors in the Fill
source are too close to the chromakey color, it may be hard to exclude them from the key.
Selecting the Narrow button uses a smaller acceptance angle around the chromakey color.
Selecting Narrow temporarily, may help you center the Hue adjustment.
Setup with a Vectorscope
It is sometimes instructive to set up a chromakey using color bars as the background
source, and watching the result on a vector scope as you perform the following procedure.
1
Turn off Narrow and set Lift to 0.

Adjust the Y-suppression knob until the black level is correct.
Setting Up a Preset Pattern Key
Each effects keyer in the Overture 1 switcher has a dedicated pattern generator that can
produce key signals in a variety of geometric shapes. The shapes can be sized and
positioned to produce the desired key signal.

Select the Fill Source
The cut and fill sources are selected using the select bus of the panel. To set up a keyer,
navigate to the desired key menu using the LCD button Adding a keyer to the next
transition will automatically navigate to the key menu for the selected keyer. Verify that the
display above the select bus shows the name of the keyer you are setting up. Select
PATT KEY as the key type on the Keyer menu.
You need only select a fill source, since the key signal is generated by the pattern
generator. The cut source is ignored.
In place of a cut source, you must select a pattern from the pattern menu of the keyer that
you are setting up. Select from two pages of available shapes.
Preset Pattern Adjustments
Softness
The softness adjustment changes the softness of the edge of the key signal.
Size
The size adjustment increases and decreases the size of the selected pattern.
X and Y position
Some of the patterns may have their center point repositioned. To position a pattern,
navigate to the pattern selection page of the keyer you are setting up. Use the joystick to
move the pattern vertically and horizontally.
See Appendix C: Wipe Library, to review which patterns may be positioned.
To re-center the pattern, press the pattern select button of the current pattern in the menu.
This will reset the position and symmetry of the pattern.
Symmetry
Some of the patterns may have their symmetry or aspect ratio adjusted. Circle patterns
may be adjusted to become horizontal or vertical ellipses. The symmetry adjustment is on
the Z axis of the joystick when you are on the pattern selection page of the keyer you are
setting up. Twist the knob of the joystick to adjust its symmetry.
Reverse
The Reverse button is used to invert which region is filled with the fill source. For example,
fill a region outside of a circle by positioning the circle wipe as desired and then selecting
Reverse.
Setting Up DVEs
Upstream effects keyers have DVEs that can transform the fill and key signal used by the
keyer ( The video sources may be resized, positioned in X and Y, and rotated about their
center. See the manual section on DVE Moves for details about positioning and moving
the DVEs. This section describes how to set up the keyer to display the output of the
DVEs.

Figure 19. DVE signal flow
The DVEs may be used in one of two ways:
•
Create a “picture-in-picture” box, which may have a border. The
DVE creates the key signal to insert the box into the background video.
•
Fly a key by transforming both the fill source and key that were
created by some other key processing method.
To use a DVE in the first manner, chose DVE as the key type for effect key 3 or key 4.
Select the Fill Source
Select the video source that will be displayed inside the box. Since the DVE will create the
key signal for the box and border, the cut source is ignored.
DVE Adjustments
All adjustments are accessible from the DVE page of the menu.
X and Y position
The X and Y position of the DVE is adjusted with the joystick.
Size
The size of the DVE is adjusted with Z axis of the joystick. Twist the knob of the joystick to
increase or decrease the size of the DVE box.
H and V size
Separately adjust the horizontal or vertical dimension of the DVE box with the H size and V
size knobs.
Border
Adjust the width of the border using the Border Knob. The color of the border is adjusted
in the Border sub menu.
Rotation
Spin the box around its center point with the Rotation adjustment knob.
Rotation Reset
Press Rot Reset to quickly set the rotation back to 0.
DVE Reset
Press DVE reset turns off the border, and positions the size and position of the DVE to full
screen. If you ever lose track of the DVE during adjustment, you can press reset to bring
the DVE to full screen, then squeeze it back into position.
Flying a Key
When flying a key, the DVE is a modifier of fill and key signals that have already been
computed though some other keying method (Figure 20). A DVE may fly any type of key;
Luminance, Chromakey or Preset Pattern. The key menus for Key3 and Key4 contain a
Fly button. Pressing the Fly button turns on the DVE to transform both the Fill video and
the key signal before the keyer. The DVE positioning controls are included in a sub-menu,
and are similar to the controls discussed above.
Inserting a Sign Language Interpreter in the lower left-hand corner of the screen is a good
example of flying a key. The Interpreter is framed in full screen isolation. A preset pattern
key can be positioned to key in just the Interpreter inside a circular key. Pressing the Fly
buttons allows you to reduce the image of the Interpreter, and position it anywhere on the
screen. This is accomplished using only a single keyer, without tying up resources
required anywhere else in the switcher.

Key Memory
A particular fill source will often be keyed in the same way at all times. As an example, the
fill output from a character generator will always be keyed with the cut output from the
character generator. If the output is a shaped key, then a shaped luminance key will
always used.
Since you invest time in setting up your keys, it is convenient to have the switcher
remember the settings, and re-use them automatically in the future. This is the function
performed by key memory. After setting up a key, pressing the Set Keymem button stores
all of the settings from the current Keyer.
If key memory is turned on, when you select a fill source for a keyer, all of the keyer
settings that were stored for the selected Fill source are recalled. A key memory saved on
a particular keyer, can be recalled on any other keyer with similar capabilities.
Luminance keys can be saved and recalled on any of the Keyers in Overture 1.
Preset Pattern and Chromakeys can be saved and recalled on all upstream keys.
Key memories are stored on the Opera memory card, so they are retained by the switcher
even when the power is off.
Setting Up Key Memory
Use these steps to set up key memories:
1
Turn off key memory. At the top level of the menus, ensure that the Key Mem button is not
illuminated. If it is, press the button to turn it off. Since key mem automatically recalls
keyer settings when a fill source is selected, it can be confusing to set up keyers with key
memory enabled.
2
Select a source that will be used as a key fill source. Set up the keyer according to the
correct section from above. After the key is adjusted the way you want, press Set
Keymem.
3
Repeat step 2 for any other source that will be used as a key fill source.
4
Turn key memory on.
5
Verify your settings by preview a keyer, and select each fill source that you set up. The
keyer should be properly configured for each source.
6
To save the current setting to the Opera memory card, return to the top level of the menu
(HOME), and press Save Keymem.
Note: If you turn off the switcher without saving the key memories to the memory card,
your changes will be lost.
To Clear a Key Memory for a fill source, hold shift and the “set KeyMem” selection will
become “Clear Keymem”. You simply then press the fill source that you would like to
clear.
Key Masks
Each keyer, Effects or DSK, has a adjustable mask. The Mask Menu is accessed through
any of the Key menus. The mask consists of left, right, top, and bottom of the active video
window.
Adjusting Key Mask
Select the Mask Menu. Note that the display now shows soft key assignments for mask
and mask rst (reset). Turn on mask by selecting the soft key. Now the rotary encoders
control the sides of the mask.
Use the rotary encoders to adjust the mask. Mask Rst will reset to default values of no
visible mask.
KeyMems set for sources will retain mask settings.
Aux Selection
Defining Aux Outputs
The Overture 1 production system has 12 routable aux outputs.These outputs are routable
from the panel to any source, Program, Preview, or Cleanfeed.
All outputs are timed.
Selecting Aux Outputs
Using the LCD buttons or direct access on the designation bus, select the aux bus to be
routed.
Any source (mapped to a crosspoint switch) can be selected as an output of an Aux by
selecting that source on the Select Bus. Shifted sources will require the use of SHIFT with
the select bus. In order to select Program (prog), Preview (prev), Cleanfeed 1 (clfd1), or
Cleanfeed 2 (clfd2) you must select both SHIFT and CUT/FILL at the same time to access
‘Shift2’ selections.
The switcher will perform a “clean” switch when changing sources through an Aux.
DVE Moves
Description of DVE Moves
DVE moves can be set for immediate use, and saved for recall. Each move consists of 2
user-defined keyframes: A and B. From each keyframe, other moves are executable.
Opera will interpolate the DVE action between the keyframes to create a smooth motion
path.
Building DVE Moves
Using the LCD buttons, from the Home menu select EFF KEYS to go to the Effects Keyers
menu. From the Key menu, select DVE as the key type. Now select MOVE MENU.
Setting Keyframes
Position the DVE for Keyframe A (start of move). Press Set Keyframe A.
Position the DVE for Keyframe B (end of move). Press Set Keyframe B.
Playing Keyframes
After A and B keyframes are set, a number of moves are possible:
When the DVE is at Keyframe A, Set Keyframe A will be lit.
When the DVE is at Keyframe B, Set Keyframe B will be lit.
To move from A to B, press Run to B. The move will execute at the rate specified as the
Recall Rate. (See Operation: Sources and Transitions, Rates)
To cut from A to B, press Shift + Run to B. The move will execute in 1 frame.
To move from B to A, press Run to A. The move will execute at the rate specified as the
Recall Rate.
To cut from B to A, press Shift + Run to A. The move will execute in 1 frame.
To move from either keyframe to full screen, press Run to Full. The move will execute at
the rate specified as the Recall Rate.
To cut from either keyframe to full screen, press Shift + Run to Full. The move will
execute in 1 frame.
To move from either keyframe to infinity (straight back from current position), press Run to
Infinity. The move will execute at the rate specified as the Recall Rate.
To cut from either keyframe to infinity, press Shift + Run to Infinity. The move will
execute in 1 frame.
After moving to infinity, press either Run to A or Run to B to return from the last infinity
location.
Run to Infinity also offers other executable moves.
By entering a numeric argument, the DVE will move from it’s current position to infinity, in a
specified direction.

Creating Multi-keyframe moves
You can link Saved Moves to create multiple keyframe moves.
Position the DVE for Keyframe A (start of move). Press Set Keyframe A.
Position the DVE for Keyframe B (end of move). Press Set Keyframe B.
Enter a number (for this example, enter 10) and press Save Move.
DO NOT MAKE ANY CHANGES TO THE DVE POSITIONING OR SIZE.
Press Set Keyframe A.
Position the DVE for Keyframe B (end of move). Press Set Keyframe B.
Enter a number (for this example, enter 11) and press Save Move.
Repeat the above process until you have saved all the keyframes for the move.
Playing Multi-keyframe Moves
Recall (for this example 10). The DVE will position at Keyframe A. Then, Run to B.
Recall (for this example 11). Because Keyframe A of DVE Move 11 is the same as
Keyframe B of DVE Move 10, the DVE will not change. Then, Run to B.
Repeat the above process until you have recalled all the keyframes for the move.
Using the Frame Buffer
Accessing the Frame Buffer
The Overture 1 system has (2) internal Frame Buffers (Fbuf). The Fbuf is used for capture
and display of still images from video. Stills are saved “globally” and can be accessed by
any operator Mode. (See the Chapter on Operation User Configuration.)
Stills are stored on the Compact Flash card supplied with the switcher. There is room on
the supplied CF card for approximately 200 stills.
Frame Buffer controls
Using the LCD buttons, from the Home menu select FBUF to go to the Frame Buffer
menu.
Frame Buffer sources
Any source (mapped to a crosspoint switch) can be routed into the framebuffer by
selecting FBuf on the designation bus. Shifted sources wil require the use of SHIFT with
the select bus.
Capture / Saving captured stills
Select the Fbuf x-point on Program so it can viewed on a monitor.
NOTE: This step is for monitoring only – Fbuf does not need to be selected on a x-point to
Save or Recall a still.
Select a source for the Fbuf (preferably with a moving image). FRZ (Freeze) should be off.
The source should pass through the Fbuf.
Press FRZ to capture a frame. Pressing FRZ again will release the frame and return to
“pass through”.
After capturing the desired frame, the Fbuf can be viewed as a frame or as a field.
(Viewing as a field will reduce or eliminate inter-field jitter) The Fbuf defaults to FRZ FRAM
(frame) on. To change the view to field, press FRZ FIELD.
To save a still created in the Fbuf, enter a number and press SAVE FBUF. The still will be
written to the Memory disk as a .nov file, referenced by the number selected, i.e.
still10.nov. See the section on Importing and Exporting Nova Grpahics for more
information on stills.
Stills are saved “globally” and can be accessed by any operator Mode.
CAUTION: there is no over-write protection for stills. Be careful not to overwrite other
desirable stills. You may want to copy your stills to a computer or another compact Flash
card.
Recalling stills
To recall a still, enter the number of the still and press RCL FBUF.
Or, use the rotary encoder indicated for Framebuffer File to dial in a still by number, and
press RCL FBUF.
Note: Recalling stills are not instantaneous. You will see jittering as the still writes to the
frame buffer. If it is desirable to recall stills on-air, make sure that Freeze Field is selected
(lit). Now the stills will load and visually appear to transition as a horizontal wipe.
Recalling Alphas
Opera supports targa files with embedded alphas. For more information on using targas
see the section on Importing and Exporting Nova Graphics.
NOTE: To use alphas from the Frame Buffer, ALPH must be mapped as an available
crosspoint.
To recall an alpha, enter the number of the alpha and press RCL ALPHA.
If you have a still with a corresponding alpha (they should have the same number) ente
rthe number and press RCL BOTH.
Deleting stills
Stills can be deleted from the Memory card by editing on a computer. Locate the “stills”
folder, and delete the still.
Another option would be to “overwrite” the still, preserving the file and numbe
Adjusting Transition Rates
Controlling Transition Rates
Using the LCD buttons, from the Home menu select RATES to go to the transition rates
menu.
Video Rates
From the RATES menu select VIDEO RATES. The rotary encoders are now assigned for
the different auto transitions available:
TAKE – next transition
DSK1 – downstream key 1 auto
DSK2 – downstream 2 auto
FTB – Fade to Black auto
Use a rotary encoder to “dial-in” a rate, or the numeric keypad to enter a rate.
Once the desired rate is entered, press the corresponding soft key to set the rate.
DVE Rates
From the RATES menu select DVE RATES. A DVE rate is the time allotted a DVE to
move from a Keyframe to another Keyframe in a DVE Move.
The rotary encoders are now assigned for the DVE1 and DVE2.
Use a rotary encoder to “dial-in” a rate, or the numeric keypad to enter a rate.
Once the desired rate is entered, press the corresponding soft key to set the rate.
Using Color Matte Generators
Controlling Color Matte Generators
Using the LCD buttons, from the Home menu select COLOR to go to the Color matte
grenerators menu.
Adjusting the Colors
From the COLOR menu select COLOR1. The rotary encoders are now assigned for
adjusting the attributes for the color matte generator CLR1.
From the COLOR menu select COLOR2. The rotary encoders are now assigned for
adjusting the attributes for the color matte generator CLR2.
Using the Color Matte Generators
To use CLR1 and / or CLR2, they must be assigned as source crosspoints for the switcher.
Saving Colors
To save a color, enter a number using the numeric keypad and press the soft key assigned
for save clr.
Recalling Colors
To recall a previously saved color, enter a number using the numeric keypad and press the
soft key assigned for rcl clr.
Opera Memory Card
Memory Card Overview
The Overture 1 comes standard with a 256 Mb CompactFlash memory card, pre-loaded
with a default configuration from the factory. This card must be present when the switcher
is first turned on, but can then be removed at any time after the switcher has booted
without affecting switcher operation. It must however, be present for any file I/O operations
to take place. The identity4 CompactFlash memory card interface has 2 main functions:
Booting up the Overture 1 hardware and software configuration
Providing an industry-standard storage medium for stills and effects.
Supported Card Types
The Opera switcher has been certified to operate with SanDisk CompactFlash memory
cards up to 2 Gb in size. Due to the use of the FAT16 file system, cards larger than 2 Gb
are not currently supported. Also, CompactFlash memory cards by manufacturers other
than SanDisk Corp. are not certified to be compatible with the identity4, though other
brands may be compatible.
Some CompactFlash manufacturers, such as Lexar, have implemented high-speed
caching for fast writes in digital photography applications. Memory cards with high-speed
caching are not compatible with the identity4 switcher.
Disk Formats
Opera supports a FAT16 file system, similar to many digital cameras. It has a further
requirement that the card must have a maximum of 1 reserved sector in the Master Boot
Record. This is compatible with the way Windows 98, Windows NT, and Windows 2000
format a FAT16 file system.
Cards can be successfully re-formatted under any of the above operating systems using
the following syntax:
format volume [/fs:file-system] [/a:UnitSize]
for example:
FORMAT D:/FS-FAT /A:1024
Formatting Memory Cards with Windows XP
In Windows XP, the DOS format command formats the CF card with 2-8 reserved sectors
depending on the density of the CF card. The DOS format command under Windows XP
does not allow you to specify the number of reserved sectors needed, so an alternate
formatting tool should be used.
Some CF card readers are delivered with a disk formatting (or disk initialization) utility that
formats the CF card with the expected default value of one reserved sector. You can install
this utility or other third-party disk format utilities (that allow you to specify the number of
reserved sectors) on your Windows XP machine and use it to format the CF card.
Alternatively, you can use a non-Windows XP machine or a digital camera to format the CF
card. Once the CF card is correctly formatted, you can use Windows XP to perform normal
file access (read/write) operations without causing any additional problems.
Echolab has also found a third-party utility on the web that can be used to successfully reformat a CF card to make it compatible with the identity4 switcher. This utility, mkdosfs.exe,
can be found at the following Web site:
http://www.mager.org/mkdosfs/
Use the default mkdosfs command to format the CF card.
For example: c:\> mkdosfs D:
The default mkdosfs command automatically formats the CF card in either FAT12 or
FAT16 format, with at least two sectors-per-cluster, and only one reserved sector.
Opera File and Directory Structure
See Figure 21 for a sample of a typical directory image of a Opera CF card image
Root directory
Starting from the root directory, there is a single file named xilinx .sys that must not be
edited or removed. This is an Echolab-generated file that points Opera to the appropriate
sub-directories to boot the Opera system.
There is also one file folder named “echolab.” This also must not be re-named or moved.
Figure 21. Typical memory card directory structure
Mode Sub-Directories
Within the Echolab folder, there are eight different mode directories, named appropriately
mode0 through mode7. These correspond to the mode switch on the front of the Opera,
and contain the system and user files for each of the eight boot modes available on the
mode switch,
The system.ace file is a large binary file containing all the hardware and software files used
to boot and run Opera. There are no user-editable functions within the system.ace file.
Each mode sub-directory also has a config.txt file that stores user preferences for the way
the switcher boots up in that mode. These user preferences include source naming and
mapping, tally mapping and many other functions associated with customizing the
switcher. See Appendix B on page 85 for more details about this file.
There may also be a key.mem file in the mode sub-directory. If any key memories have
ever been set up and saved while operating in this mode, this is the binary file where all
those key memory parameters such as clip, gain and key source will be stored. No user
editable functions here – key memories are set up and saved from the switcher front-panel
only.
NTSC and PAL Sub-Directories
While the mode sub-directories hold information specific to a certain boot mode, the NTSC
and/or PAL sub-directories contain files that are globally known from any boot mode.
It is here that there are common storage sub-directories for full color stills, luminance-only
alpha stills, and the targa files used for organic wipes.
stills
This directory contains full 24-bit color stills used with the Opera’s color frame-buffer
functions. Stills in this directory are sequentially named as STILLxxx.nov, so that the stills
can be recalled by number from the front-panel. The stills are stored in an Echolab specific
.nov file format, in native 4:2:2. A Photoshop plug-in is available to read and write files in
this format, as well as a pc-based graphics utility for file conversions.
alphas
This directory contains 8-bit alpha’s that can be recalled into the alpha frame buffer. These
files are also sequentially named ALPHAxxx.tga, for easy recall. Note that these files are
stored in a standard, un-compressed 8-bit TARGA file format.
wipes
This directory contains all the organic wipe patterns used by Opera. These files are
sequentially named WIPExxx.tga, for easy recall. Note that these files are stored in a
standard, un-compressed 8-bit TARGA file format, just like the alpha-channel files.
Root Sub-Directory
This sub-directory contains html files that are served up by the internal web-server when
the Opera switcher is called up on a network.
Importing and Exporting
Opera Graphics
The Nova and Opera families of switchers has optional software that enables you to use
graphics effectively with your video production.
The Nova / Opera Graphics Utility
The Nova Graphics Utility is an optional software application for exchanging images
between a computer running the Windows operating system and the frame buffer of the
identity4 switcher. It also converts image files to and from the following formats:
File Format
Nova proprietary image format
Targa Files 24 and 32 bit
Windows Bitmap Image
Graphics Interchange Format
Joint Photographic Experts Group
Portable Network Graphics
Extension
.nov
.tga
.bmp
.gif
.jpg or .jpeg
.png
Photoshop Format Conversion Plug-In
The utility software includes a plug-in module for Adobe Photoshop image-editing software.
If you have Photoshop software, installing this plug-in allows you to open and edit .nov files
with Photoshop. It also converts any Photoshop-compatible image with the appropriate
color mode and size directly to the .nov format.
System Requirements
The Nova Graphics Utility is compatible with computers running the Microsoft Windows
2000 or Windows XP operating system.
Image Size and Aspect Ratio
The Opera 3408/16 switcher operates in both PAL and NTSC video standards.
Both PAL and NTSC video monitors have an aspect ratio of 4:3, but the active image
areas have different numbers of pixels.
Standard
Horizontal Pixels
Vertical Pixels
NTSC
720
486
PAL
720
576
Neither standard has the ‘square pixels’ that are customary in the world of graphics on
computer displays. You must work with your image editing tool to control aspect ratio
distortion when your graphics are displayed on video screens with ‘non-square pixels’.
The gamut, or acceptable color range, of video images is smaller than the gamut of
computer images. Very saturated and bright colors produce gamut errors when converted
to video. Some image editing tools provide filters to help you work within the limited range
of legal video colors.
There are many external references that contain helpful information on managing the
aspect ratio, resolution and color challenges of displaying computer generated graphics on
video.

Note: You can also drag the image file from a Windows Explorer window and drop it into
the picture area of the Conversion tab.
2
Click Save As and select a drive and folder for the image file. Select a file format, type a
file name, and click Save.
Using the Photoshop Plug-In Module
When using Adobe Photoshop and the Nova Graphics Utility plug-in to save an image in
the .nov format, you must resize the image to 720x486 pixels (NTSC) or 720x576 pixels
(PAL) and convert the image color mode to RGB before saving. Attempting to save an
image with other dimensions or a different color mode will display a file-format module
interface error.
For more information about resizing images or changing color mode, see your
Photoshop instructions or online help.
