Manual Conventions
In this manual, all Control Panel keys are called buttons to avoid confusion
with the video keying process.
Keycap labels appear in bold capital letters: the 3D TRANS button, the
RUNll
ll
button. Menu names are capitalized: the Warp menu, the Input menu.
Softkey labels are in bold upper and lower case italicized letters: the Rotate soft-
key. Softknob labels appear in bold upper and lower case letters: the H Pos soft-
knob. Otherwise, softknobs appear as softknob A, softknob B, softknob C, and
softknob D, starting on the left with softknob A.
A sequence of button presses appears with long dashes (—) separating the but-
tons: MODIFY — ALL — ENTER . Holding one button down and pressing
another appears with a plus (+). For example, holding CLEAR and pressing the
3D TRANS button appears as CLEAR + 3D TRANS .
Depending on your input and channel configurations, a channel can process a
video signal, a key signal, or a drop shadow derived from a key signal. This man-
ual uses the word image generically to indicate the channel's output (video, key,
or shadow).

System Description
Standard Features
DVEOUS
TM
is a 10-bit, frame-based, digital video effects system that is switch-
able between the 525 and 625 line standards. It offers the most advanced feature
set ever seen in a real-time effects device. DVEOUS' unique standard features
include the following:
nn
nn
SuperShadow – a full-bandwidth drop shadow.
nn
nn
An internal Combiner that keys up to two DVE channel pairs and the
optional Target Framestore over a background.
nn
nn
A Background Framestore that can feed live or frozen images to the internal
Combiner as a background.
nn
nn
SurfaceFX, which combines the powerful texture and 3D light sourcing
tools. There is an internal Pattern Framestore for generating video test
patterns and textures. You can use any input to the routing matrix, including
video and key inputs and the SuperMatte generator, as the source for a
texture.
nn
nn
SuperMatte color generator for creating dual color washes and patterns.
nn
nn
Four independent input freeze buffers (two for video, two for textures) per
DVE channel pair.
nn
nn
UltraWarp advanced image warping feature.
nn
nn
Channel configurations. One of the features that makes DVEOUS unique is
its flexible channel configuration. The standard unit has twin channels: one
main channel dedicated for video, and a second channel that can be used for
video, key, or shadow. The A video transformation path is a full-bandwidth
video channel. The B channel can process key signals (luminance only), but
is also a full bandwidth video channel. This lets DVEOUS operate in three
modes:
• Video/Video – you can control the twin channels independently.
• Video/Key – you can control the key channel independently.
• Video-Key/Shadow – The key follows the main video channel, with inde-
pendent control of the shadow.
nn
nn
Two dual serial component digital input modules or two analog composite
input modules (providing four input sources) are standard in the particular
I/O package you ordered. Each digital input module can provide two
independent video signals. Each composite input module provides one video
plus associated key input. Additional input modules, in any supported
format, are optional. DVEOUS supports a maximum of 12 inputs (six dual
input modules).

The DVEOUS chassis supports two output modules, and there are two
types you can choose from. Both types have a serial component digital video
outputs and digital key outputs. They differ in their analog outputs:
• Composite analog video and key outputs
• Component analog video and key outputs
nn
nn
The DVEOUS Control Panel has a high resolution graphics display and a
3.5" high density (1.44MB) MS-DOS format floppy disk drive. You can
use the floppy drive to store and recall effects and engineering setup files.
nn
nn
Remote interfacing capabilities. DVEOUS can control external switcher
aux buses with frame accurate front/back switching. Serial interfaces let
external devices, such as a switcher or edit controller, control DVEOUS.
DVEOUS supports the Abekas LINC timeline control, SMPTE, Sony
VTR, GVG CPL, and Phillips/BTS Diamond Digital Switcher protocols.
There are also 12 GPI (General Purpose Interface) inputs and 12 GPI
outputs.

An optional second DVE board adds a second pair of twin channels to
expand DVEOUS to a full two-channel (each channel has both video and
key) or a four-channel (video only) system.
nn
nn
DVEOUS supports up to 12 inputs (six dual-input modules). You can add
input modules in any combination to suit your application:
• Dual Serial Digital – two identical 10-bit inputs; either can be video or
key.
• Dual Parallel Digital – two identical 10-bit inputs; either can be video or
key.
• Dual Component Analog – two identical 8-bit resolution inputs; either
can be video or key. Both are software selectable for SMPTE, Betacam
®
(525 or 625, setup or no setup), MII®, RGB (setup or no setup), or key
(setup or no setup). Sync must be present on Y or G on the A input
source; the B input can lock to the A input if sync is not present on the B
input source (such as a key source without sync).
• Component Analog Video Plus Key – one each video and key input at 10-
bit resolution. The video input is software selectable for SMPTE, Betacam
(525 or 625, setup or no setup), MII, or RGB (setup or no setup). The key
input is selectable for setup or no setup. This input has an external sync
input, or can take sync on Y or G on the video input; the key input can
use sync from the video input if separate sync is not present.

• Composite Analog Video Plus Key – one each video and key input at 10-
bit resolution. This is selectable for 525 (NTSC) or 625 (PAL) operation,
and has high impedance looping inputs for connection to multiple
devices. It also provides advanced adaptive comb filtering for maintaining
the quality of moving images and high resolution graphics.
nn
nn
A separate Channel Output module is available as an option. This module
provides the output from each channel pair upstream of the Combiner
feeding the main output module. Each Channel Output module has video
and key outputs for its respective channel pair (1A/1B or 2A/2B), with the
video unshaped and not keyed over a background. They occupy the input 9/
10 and/or 11/12 slots, which means that have 8 inputs available in this
configuration. The Channel Output format is serial component digital only.
nn
nn
The Shot Box option is a small Control Panel intended for use in an on-air
or live environment for recalling and running effects. Its buttons duplicate
those in the On-Air and Timeline Control sections on the main Control
Panel. It lets you directly access any effect and any keyframe in an effect. You
can also freeze the input signal to each channel and run effects forward or
backward from the Shot Box.
nn
nn
The reTouch Color Corrector option offers wide range color correction and
modification in either RGB or YUV space for each DVE channel input
independently.
nn
nn
The Defocus option allows wide band defocusing of the luminance or
chrominance in an image, or both. It is dual channel: you can use it on one
or two video signals, or on one video and one key signal or the background.
Defocus controls include independent horizontal and vertical defocus
settings.
nn
nn
The Target Framestore option lets you create trails with variable decay (with
either video or a matte fill), sparkles with variable size and intensity, motion
blur, and montage (drop-ins) with selectable priority for live video over or
under existing drop-ins. This option also stores Z, or depth, information,
letting you build solids easily and move live images in front of or behind the
frozen images automatically.
nn
nn
An External Floppy Drive can be connected to the DVEOUS control panel
when console mounting blocks access to the on-board drive.
nn
nn
Expanded Memory adds 1 Megabyte of RAM to the Combiner board to
increase total keyframe effects from 900 to 2200.
nn
nn
The CPL Protocol Converter module interfaces DVEOUS to switchers
using GVG Control Protocol Language (models 3000 and 4000).

Reference Requirements
You must operate DVEOUS locked to an external reference input. A switch on
the Combiner Controller board front edge selects the system line rate (525 or
625). It accepts black burst (color black) or composite sync as a reference input
if the component output module is installed, but requires black burst if the
composite output module is installed. The reference input includes a switch
selectable 75-ohm termination or high impedance loop through for daisy
chaining the reference signal to other devices.
Control Ports
There are several control ports on the rear of the DVEOUS Main Chassis.
nn
nn
The Aux and Editor ports are used to support various protocols. They have
identical protocol selections. The Editor port is usually used for serial
remote control of DVEOUS as a slave device using the SMPTE or Sony
RS-422 protocols. The Aux port is typically used for auxiliary bus control of
several switcher types.
nn
nn
The LINC ( L ocally I ntegrated N ode C ontrol) port provides timeline control
of DVEOUS from any Abekas digital video switcher.
nn
nn
Two GPI (General Purpose Interface) ports supply extensive input and
output switch closure-based remote control. The GPI outputs can also
provide tally information. Input and Output functions are assignable and
trigger-edge mode is selectable in the Remote Setup menu. Pinouts and
specifications for the GPI ports are provided in Section 2. Configuration is
discussed in Section 6, Setup Menus.

Overview ofTerms
The terms below are commonly used when discussing DVEOUS.
nn
nn
Channel— The term “channel” has been used to describe either the video or
key processing path, inputs, or outputs (the video channel, or the key
channel output). Most DVE systems process luminance and chrominance in
the video path but only luminance in the key path. Usually, a “two-channel”
system or effect refers to the number of video images involved, and implies
that the key channels are included.
DVEOUS has the unique ability to process either a key signal or a video sig-
nal on the second channel. This means that the standard DVEOUS system
can have one video and one key path, or two video paths and no key path; it
can generate raster-shaped key signals at the output.
In this manual, “channel” can refer to a video path or a key path, and, unless
specifically noted, they are interchangeable. Each twin channel DVE board
has a main video channel (1A) and its “twin” video, key, or shadow channel
(1B). The second (optional) DVE board adds an additional video channel
(2A) and twin video, key, or shadow channel (2B).
nn
nn
Multichannel— ”Multichannel systems” in the past always referred to the
video channels, with the accompanying key channels implied. Thus, a four-
channel system had four video paths and four key paths. DVEOUS is a
multichannel system in its standard configuration, because both channels
can process video. Each DVEOUS DVE board (maximum two per system)
has twin processor channels: the video channel (A) and the twin channel (B).
You can use these channels in three different modes:
• V + V (Video + Video)— The DVE board independently processes two
video sources. All transform, warp, and lighting effects are adjustable sepa-
rately on each video channel. The DVE processor internally generates the
key signals associated with these signals. The key signals are full screen
“white” with adjustable opacity and edge softness.
• V + K (Video + Key)— The DVE board independently processes one
video and one key source. All transforms are available to the key signal
independently from the video. The key channel also has clip, gain, and
horizontal phase controls.
• VK + S (Video/Key + Shadow)— In this mode, the DVE board derives a
full-bandwidth drop shadow from the key input. It processes the video and
key (which are tied together) in the A channel, with independent control
of the shadow in the B channel. Besides the clip, gain, and horizontal
phase controls for the key part of the A channel, there are color and opac-
ity controls for the shadow channel.

Control Panel Buttons
A brief description of the Control Panel and its button groups follows.
The Menu Screen
Menu Display
The menu screen is in the upper left corner of the Control Panel. You can
adjust brightness and contrast in the Engineering Setup menu.
Menu Labels and Controls
Some of the information displayed in the menu screen changes depending on
DVEOUS' current status and the current menu. The figure below shows a typ-
ical display.
The top line shows the current menu title, and indicates the currently selected
master channel (the one the menu settings reflect): 1A, 1B, 2A, or 2B. The
master channel display does not appear in global menus.
A menu can have up to three different softkeys. The softkey labels appear on the
left side of the menu screen. Select a softkey by pressing the button next to its
label. When you press a softkey, a black highlight indicates that it is active. If
there is more than one label for the softkey, pressing it toggles the function, and
the highlight indicates the active mode. Also, up to four parameters for each
softkey function can appear above the softknobs at the bottom of the menu dis-
play. You can adjust these settings with the softknobs, the keypad, or the joy-
stick. The motion path type assigned to the parameter appears above the
softknob values.

Enter a value in the numeric keypad, then press the corresponding A , B , C ,
or D button in the top row of the numeric keypad. For example, to enter the
value 17 in softknob A, enter 17 on the keypad, then press A . This applies to
softknobs that use numeric values.
nn
nn
Use the joystick to change softknob settings. Adjust softknob settings with
left/right arrows by moving the joystick left and right. Adjust settings with
up/down arrows by moving the joystick up and down. Adjust softknob
settings with circular arrows by twisting the joystick handle.
nn
nn You can copy a value from one softknob to another. With the keypad buffer
empty, press the keypad softkey (A,B, C, or D) for the softknob you want to
copy. This copies the value to the keypad buffer. Pressing another keypad
softkey (A, B, C, or D) enters the value in that softknob and clears the
buffer.
nn
nn You can invert a value by pressing the +/- button, then the keypad softkey
(A, B, C, or D) for the softknob. Use this for values that accept negative
numbers.
nn
nn You can also use TRIM to trim a value: press 1— TRIM — Ato add 1 to
the value in softknob A.
nn
nn You can reset values and entire menus to their default settings:
nn
nn Press CLEAR, then A, B, C, or Dto reset the softknob value to default.
Hold CLEAR and press more than one keypad softkey (A, B, C, or D) to
reset multiple values.
nn
nn Hold CLEAR and press a softkey to clear all the values for that softkey to
default. This resets both the softkey setting (if it is a toggle or flag) and any
softknob values.
nn
nn Hold the CLEAR button and press a menu button to reset all the values for
that menu to default. This resets all softkeys and softknob values.

A keypad buffer appears in the lower right corner of each menu. The buffer can
display one of the following:
nn
nn Empty (default).
nn
nn A number waiting to be assigned to a softknob.
nn
nn A number and the word Trim.
nn
nn The word Align.
nn
nn The word Clear.
nn
nn The +/- symbol.
nn
nn The message <<Set Path>> and a list of the path types: JP (jump), LN
(linear), SL (smooth linear), T1 (Tension Continuity Bias 1), T2 (Tension
Continuity Bias 2), and SM (smooth). A cursor indicates the currently
selected path type.
The center of the display shows information about the current timeline and
effect. The top line (CTime) indicates the current point on the effects timeline
as seconds:frames. The next five lines indicate the current keyframe and total
keyframes for each channel's effect. For example, if channel 1A is on keyframe 2
of a five keyframe effect, the display reads Ch 1A : Kf 2 of 5. There are two Free
Kf lines. The first one shows the number of keyframes available for addition in
the current effect (there is a maximum of 300 keyframes per effect). The bottom
line shows the number of keyframes available in the system keyframe pool (a
total of over 900 with the standard 1MB memory, 2200 with the optional 2MB
memory).
Below the effect information display area is a single line edit buffer that shows
your keyframe editing command strings (TimeFrame Effects Editor or Quick
Keyframes keystroke sequences). If DVEOUS recognizes the command string,
it confirms by displaying OK at the end of the string when you press ENTER. If
it does not, an error message appears after the unrecognized command string.
You can “lock” the joystick control to the current menu settings, then change to
a different menu and use the softknobs to control the settings there. The joy-
stick still affects only the settings it is locked to.

Channel Select Buttons
The Channel Select buttons include GLOBAL, 1A, 1B, 2A, and 2B. They are
the red buttons on the left side of the Control Panel, below the menu display.
1A and 1B are twin channel number 1. 2A and 2B comprise the second
(optional) twin channel. The global channel affects every channel equally. Press
a Channel Select button to light its LED and make it the active channel. The
menus reflect the status of the active channel, and any changes you make in the
menus affect the active channel.
The LED displays above and below the A Channel Select buttons read VIDEO
to indicate that these channels are video channels. The displays above and below
the B Channel Select buttons can be either VIDEO or KEY, depending on how
you have configured your channels. See the discussion at the end of this section
for more details on configuring channels.
When a channel is designated as the “master,” its settings appear in the menus.
You can have more than one channel active at a time, but only one channel can
be the “master” channel. Though the menus reflect the master channel's set-
tings, any changes you make in the menus affect all active (selected) channels.
Hold a Channel Select button for half a second to designate it as the master
without de-selecting other channels. Double press a Channel Select button to
select it as the master channel and de-select all other channels. You can toggle
any other channel on and off after designating a master channel by pressing its
Channel Select button once.

Numeric Keypad
The numeric keypad is located under the System buttons. Use the keypad to
enter effect numbers, keyframe numbers, parameter values, etc. The A, B, C,
and Dbuttons let you enter values into the softknob settings. For example, to
enter the value 17 in softknob A, enter 17 on the keypad, then press A.
You can invert a value by pressing the +/- button, then the A, B, C, or Dbutton
for a softknob. Use this for values that accept negative numbers.
You can use CLEAR to erase the contents of the keypad buffer, the contents of
the keyframe edit dialog, or reset entire softkeys or menus to default.
You can use TRIM to adjust values. For example, press 1 — TRIM — A to add
1 to the value in softknob A.
Press ALIGN to put the word Align into the keypad buffer. Now pressing a key-
pad softkey (A, B, C, or D) brings the corresponding softknob value to its near-
est “nominal” value. For example, aligning a rotation value of 39 degrees sets it
to 45 degrees. Pressing ALIGN, then a menu softkey (left side of the display)
sets all the softknobs to their closest nominal value.
Pressing PATH displays the available motion path types in the keypad buffer.
You can assign a motion path type to any parameter by pressing PATH to select
the motion type in the keypad buffer, then the keypad softkey (A, B, C, or D)
for that softknob.
