Getting Acquainted with Nova 1416
Overview
Given its impressive standard feature set, the Nova 1416 can only be compared to switchers
that are twice its price. The Nova 1416' s sleek new panel fits in a standard rack, is perfect
for all production environments and in particular space-limited operations including flight
packs and OB vans.
The Nova 1416 has industry standard "lookahead' preview architecture, broadcast quality
10-bit NTSC / PAL Serial Digital Video and offers unprecedented ease-of-use and familiar
operation.
The Nova 1416 provides high-speed, next-generation interconnectivity. Echolab Nova
Series switchers have 10/100-Mb Ethernet ports, supporting simultaneous connections to
the outside world through Web, TFTP & XML-RPC servers. The Web server enables an
operator to remotely access the switcher from anywhere in the world via a web page to
check on status and configuration.
Connectivity
The XML-RPC Server provides a high-bandwidth remote control protocol for operation of
any switcher function over a local or remote Internet connection. Functions such as remote
aux panels can take place without the complex and proprietary serial daisy-chain
connections required by previous generations of switchers.
The TFTP Server allows an operator to upload and download graphics to the Nova 1416's
frame buffer. Working in conjunction with a remote PC or Macintosh running Photoshop, a
user can create a full 32-bit image, such as a lower third, and then transfer both the
foreground and alpha directly to the Nova to set up a key. This provides a basic, yet
complete CG capability for those with a limited budget. Also images can be captured in the
switcher's frame buffer and sent back to the PC over the TFTP server to import into
programs such as Photoshop for retouching.

Video Layering
The Echolab Nova 1416 has six keyers for unprecedented layering in a switcher of this size.
This offers amazing power in terms of creative control. Four upstream effects keys support
luma, chroma, & preset pattern keys. Two of the four effects keyers have integrated DVE' s.
Two downstream keyers allow title keying for graphics, logos, and bugs. Both background
and key transitions can be set up and previewed with Echolab' s complete look-ahead
preview system. Transitions include dissolves and a rich library of over 600 wipe patterns.
Upgradeability and Flexibility
The Nova 1416's system-on-chip architecture provides for centralized storage of firmware
and hardware configuration updates on a Compact Flash memory card. Up to eight custom
or previous versions can be stored on the card. Multiple versions on the card allow for
different users to customize their switcher for show-specific needs. Previous versions stored
on the card allow a user to confidently upgrade their switcher without the fear of a loss of a
previous working version. No messy, unpredictable, risky upgrades.
The interconnectivity, smart architecture and advanced firmware of the Nova 1416 allow us
to offer a lifetime guarantee of free upgrades to the core software. Future upgrades will be
easily accessed for download via the Internet. This will allow our customers to stay current
with our ever-evolving technology.
The Nova 1416's aggressive use of state-of-the-art industry standard networking means
integrating the switcher into your studio will be a snap. Plug it in, and it's ready to use: from
down the hall, or halfway across town.

Inputs and Outputs
• 16 In / 16 Out SDI : (* Echolab Conversion Available! See
www.echolab.com/Converters)
All inputs 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, Nova 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 Nova Series of SDI 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 4RU 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.

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 (ME). The ME
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).

Nova 1416 manual • Check updates at www.echolab.com/1416
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 (ME) 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.
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 a cut, mix or
wipe.
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 (Figure 1 on page 13). The operator can change the
background video or any of the four 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 Nova 1416 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.

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

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

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.
Nova 1416 manual • Check updates at www.echolab.com/1416
33
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 1416 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.
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 (Figure 1 on page 13)
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.

Nova 1416 manual • Check updates at www.echolab.com/1416
Controlling Mix and Wipe Transitions
To mix automatically at a smooth rate, press the Auto button in the transition control block (Figure
1 on page 13). 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 (Figure 1 on page 13). 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 mix and wipe 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 Nova identitity4 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
Background
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.
36
Nova 1416 manual • Check updates at www.echolab.com/1416
For the Effects Keyers, the options are:
LUMA KEY – luminence
CK KEY – chromakey
PATT KEY – pattern key
DVE – DVE key (available on upstream keyers 3 and 4 only)
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.

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 (EFF KEYS for an upstream keyer, DSK KEYS for a
downstream keyer) using the LCD buttons (Figure 1 on page 13). 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
LUM as the key type on the Keyer menu.
Pressing the CUT/FILL button on the select bus (Figure 1) toggles the assignment of the
select bus between fill and cut sources. The select bus label changes to reflect the state of
the shift button.
Select the fill source by pressing the button that corresponds to the fill video source. If the
source is mapped to a shifted crosspoint, you may need to press the SHIFT key on the
program bus.
Nova 1416 manual • Check updates at www.echolab.com/1416
37
To select the cut source, press and hold the CUT/FILL button. Then press the button
that corresponds to the cut video source.
Sometimes the same source is used as both the cut and fill source. This is known as
a self-key. To perform a self key, simply select the same crosspoint as both the cut
and fill source.
Verify the cut and fill setting by toggling the CUT/FILL button and observing the
highlighted sources.
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.
38
Nova 1416 manual • Check updates at www.echolab.com/1416
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).

downstream keyer) using the LCD buttons (Figure 1 on page 13). 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.
Matte Preview
When a chromakey is on the preview monitor, selecting Matte Preview will display the key
signal generated by the chromakey. Viewing the matte sometimes helps solve lighting or
adjustment problems.

Nova 1416 manual • Check updates at www.echolab.com/1416
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.
2
Adjusting the hue knob will offset the black point, and the constellation of the
6 color bar dots will rotate around the screen. Adjust the hue until the color
hex dots are centered around black.
3
Adjusting the gain will expand and contract the color vectors about the center.
Adjust the gain until the color bars are near their target boxes on the vector
scope.
4
Adjust the Y-suppression knob until the black level is correct.

navigate to the desired key menu (EFF KEYS for an upstream keyer, DSK KEYS for a
downstream keyer) using the LCD buttons (Figure 1 on page 13). 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.

Nova 1416 manual • Check updates at www.echolab.com/1416
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
Effects key 3 and key 4 have DVEs that can transform the fill and key signal used by the
keyer (Figure 19). 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.

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.
44
Nova 1416 manual • Check updates at www.echolab.com/1416
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 filmed 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 six keyers in the Nova
1416
Preset Pattern and Chromakeys can be saved and recalled on effects key 1
through key 4
DVE or Flown keys can be saved and recalled on effects key3 and key4.
Key memories are stored on the 1416 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 1416 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.

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 wil require the
use of SHIFT with the select bus. In addition, the soft keys can be used to select
Program (prog), Preview (prev), Cleanfeed 1 (clfd1), or Cleanfeed 2 (clfd2).
The switcher will perform a “clean” switch when changing sources through an
Aux.
Aux Monitor
Aux 12 is reserved as a Aux monitor output. Aux monitor allows you to view the
output of any Aux through a single monitor. Whichever Aux is selected using the

Using the Frame Buffer
Accessing the Frame Buffer
The switcher has 1 internal Frame Buffer (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.
Note that the Select Bus is now labeled as in use for the Fbuf Source, and the
display reads Framebuffer. The soft keys are now available as source
selections. The first rotary encoder is now assigned for recalling stills.
Frame Buffer sources
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 wil require the
use of SHIFT with the select bus. In addition, the soft keys can be used to select
Program (prog), Preview (prev), Cleanfeed 1 (clfd1), or Cleanfeed 2 (clfd2). The
switcher will perform a “clean” switch when changing sources.
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
54
Nova 1416 manual • Check updates at www.echolab.com/1416
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
Nova supports targa files with embedded alphas. For more information on using
targas see the section on Importing and Exporting Nova Grpahics.
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 number.

Configuration
User Configurations and Memory
The Nova 1416's system-on-chip architecture provides for centralized storage of
firmware and hardware configuration updates on a Compact Flash memory card.
Up to eight custom or previous versions can be stored on the card. Multiple
versions on the card allow for different users to customize their switcher for
show-specific needs.
User Configuration File Settings
Nova has user options for functionality. More options will be added in future
releases. There are 8 Modes available for users. Each Mode can have different
user settings, recalls, and Key Memory settings. Wipes and Stills are shared by
all user Modes.
The optional settings are contained in User Configuration files on the Memory
Card. Nova ships with 8 identical Modes.
To access a user’s Mode, select the Mode by number using the Mode Select
switch on the chassis. Turn on the chassis. Nova will boot using that Mode.
Editing User Configurations
Remove the Memory Card (or use the second supplied card) and insert into the
supplied Card Reader. Plug the card reader into a USB port of a separate
computer and follow that computer’s instructions to mount the Memory Card as a
removable drive. Now you can view the contents of the Memory Card and edit
files using MS Notepad or an equivalent program.

Changing Configuration
Do not change the directory structure of the Memory Card.
Do not delete config.txt or system.ace files.
Do not format the Memory Card.
Using Windows Explorer, or an equivalent program, open the Echolab folder to
view the Mode folders. Select an operating Mode (0 through 7) and open the
folder. Locate the file config.txt, and open using MS Notepad or an equivalent
program. This is the User Configuration file for that Mode. Each Mode has a
separate config.txt file.
The User Configuration file will allow you to change software settings for the
switcher.

Network Interfaces
The Nova Video Switcher executes three network services to help you manage
your switcher. Nova may also act as a client, and contact servers that contain
the Echolab Partner Products, such as a Character Generator or Clip Store.
Servers
Nova runs the following services:

Finding Your Nova
All devices on a network must have an IP address. You must know the address
of your Nova before you can access it over the network.
Nova may obtain an IP address by two methods.
Static IP address: The IP address is assigned manually, and must be included in
the switcher configuration file.
DHCP: Nova will search the network for a DHCP server, that will assign an
available IP address to the switcher automatically. DHCP must be enabled in the
switcher configuration file. It is disabled by default.
To display the current IP address of the switcher, pres the IP ADDR button on
the IO Menu Page. The current IP address will be shown in the display. If the
display reads 0.0.0.0 then the switcher is still trying to contact the DHCP server.
Check the network connections, and the status of your DHCP server.
Nova 1416 manual • Check updates at www.echolab.com/1416
65
Ping is a common network utility that is used to determine whether a specific IP
address is accessible. It works by sending low level communication packets to a
device, and waiting for a reply. Once the switcher obtains an IP address, it
becomes ping-able. Ping is only used for network troubleshooting.
HTTP Server
The HTTP server allows you to read status and configuration information from
the switcher using a standard web browser.
You access the home page at using the switchers current IP address, by entering
into the URL line of your web browser as follows.
http://192.168.1.135
TFTP Server
The TFTP server allows image files to be transferred between the switcher's
frame buffers a computer across the network. You will most often use this server
indirectly through the Graphics Import Utility, described in “Importing and
Exporting Nova Graphics.
The server supports the transfer of two file types:
Color images are transferred in a file format that matches the native resolution
and colorspace of video signals. The image is 4:2:2 YCbCr interlaced, with
dimensions that match the active region of either NTSC or PAL video. A
Photoshop Format Conversion Plugin is supplied to make seamless conversions
between this format and all popular graphics formats. The format conversion
plugin is described in “Importing and Exporting Nova Graphics” on page 71.
The Alpha channel frame buffer is loaded with a standard, 8 bit monochrome
Targa image. These files can be read and written with most popular graphics
and paint applications.
The files are not written directly to the switcher's Compact Flash Card. They are
loaded into one of the framebuffers. The framebuffer can then be saved to the
Compact Flash Card by using the Framebuffer Menu Page of the front panel.

XMP-RPC Server
The switcher may be controlled remotely through the XML-RPC server.
XML_RPC allows software running on disparate operating systems, running in
different environments to make procedure calls over the Internet. It is remote
procedure calling using HTTP as the transport and XML as the encoding. XMLRPC is designed to be as simple as possible, while allowing complex data
structures to be transmitted, processed and returned.
The XML-RPC home page can be found at http://www.xml-rpc.org It contains a
list of implementations, that permit you to build a client in just about any language
you may be working in, including many internet scripting languages.
The XML-RPC server is documented in a separate Developers Kit.
Partner Product Control
Nova controls Echolab Partner Products using a proprietary protocol to
communicate with the computers that contain the Partner Applications and
Hardware.
These protocols are optional. Check with your administrator to make sure which
protocols were ordered with your switcher.
You will use this interface indirectly though the Partner Product Menu pages of
the 1416 front panel. See “Partner Product Control” and the Supplemental
Manual for your partner product option for details.
The PC that controls the partner product must be properly configured, and
accessible on the network.
The IP addresses of the Partner Product PCs must be known by Nova. They are
entered in the switcher configuration file. See Appendix B: Configuration File
Format (page 85) for detailed information about editing the configuration file.
The protocol uses small, fixed length packets, transmitted over the UDP. Nova
contacts the servers on port 34000, and listens for return traffic on port 55555.

1416 Memory Card
Memory Card Overview
The Nova 1416 comes standard with a 256 Mb CompactFlash memory card, preloaded 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 1416 CompactFlash
memory card interface has 2 main functions:
Booting up the 1416 hardware and software configuration
Providing an industry-standard storage medium for stills and effects.
Supported Card Types
The 1416 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 1416, though other brands may be compatible.
Some CompactFlash manufacturers, such as Lexar, have implemented highspeed caching for fast writes in digital photography applications. Memory cards
with high-speed caching are not compatible with the 1416 switcher.
Disk Formats
Nova 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.
Nova 1416 manual • Check updates at www.echolab.com/1416
69
Memory Card
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 nonWindows 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 re-format a CF card to make it compatible with the 1416 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.
Nova File and Directory Structure
See Figure 21 for a sample of a typical directory image of a Nova 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 Nova to
the appropriate sub-directories to boot the Nova system.
There is also one file folder named “echolab.” This also must not be re-named or
moved.

Memory Card
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 back-panel of the Nova, 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 Nova. 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 Nova’s color framebuffer 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.
72
Nova 1416 manual • Check updates at www.echolab.com/1416

wipes
This directory contains all the organic wipe patterns used by Nova. 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 alphachannel files.
Root Sub-Directory
This sub-directory contains html files that are served up by the internal webserver when the Nova switcher is called up on a network.

Importing and Exporting
Nova Graphics
The Nova family of switchers has optional software that enables you to use
graphics effectively with your video production.
The Nova 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 1416 switcher. It also converts image files to and from the
following formats:
File Format
Extension
Nova proprietary image format
Targa Files 24 and 32 bit
Windows Bitmap Image
Graphics Interchange Format
Joint Photographic Experts Group
Portable Network Graphics
.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 Photoshopcompatible image with the appropriate color mode and size directly to the .nov
format.

75
Nova Graphics Utility
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 Nova 1416 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.
