Introduction
The DIDO LT is a high quality video processor engine. The DIDO LT supports advanced functionality
such as video format /scan rate conversions, real time image rotation (patents pending), and window
effects. All these can be controlled via IR remote and RS-232 commands. The device is small enough to
fit in tight areas. The progressive output(s) produces a high quality image using the latest 3:2 / 2:2 pull-
down, motion handling, and noise reduction technologies.
Example Setup using the DIDO LT side by side mode:
• Up to 165MHz bandwidth on the inputs and outputs.
Allows resolutions up to 1900 x 1200 @ 60Hz (narrow band sync) and can de-
interlace 1080i to 1080p
•Image enhancing capabilities including Motion Adaptive De-interlacing, Low-
angle Directional Interpolation, 3:2 & 2:2 inverse pull-down, Moiré cancellation,
color correction, adaptive flesh tone adjustments, image zoom & shrink.
•The powerful AARE (Aurora Advanced Rotation Engine) / Picture-and-Picture
(PAP) engine offers several modes of operation including:
1. Hi-resolution Dual Image or Side-by-Side (split screen) images. Perfect for
teleconferencing, security, command and control applications.
2. Image Rotation (for digital signage)
3. Translucent Overlays to maximize main image size while still seeing PiP
•Accepts digital and analog video inputs through a combination DVI/ RGBHV/
YPbPr connectors and S-Video/Composite input connectors
•Internal Event Scheduler with Real Time Clock allows AARE special effects to be
scheduled locally and among DIDO LT units when connected via the RS-485 bus
•Firmware upgradeable. New firmware releases can be easily uploaded to the
DIDO LT with the Flash utility, which is available for free from Aurora's website.

Preset keys make the usability of the DIDO LT much easier. When a preset is recalled, it will restore the
saved screen conditions set at the time of initially saving the preset. Up to 99 presets can be saved and
recalled via the menu or RS-232. Only the first 4 can be recalled with the quick keys on the remote.
Presets are very useful for effects, image resizing, and especially video wall functions. Presets 1-4 can
also be recalled via the front keypad.
Menu Structure
The menu system allows a user to control various configurations of the DIDO LT
For all menus, Up/Down arrows move the cursor (yellow highlighted selection) up/down. Central key
(SEL key) selects the current submenu/option, confirms changes, and finishes text entry (passwords,
presets, etc.). Left/Right arrows change the currently active option, if possible.
The sub-menus will be discussed in more details in the subsequent chapters.
1.1.1 Main Menu
Main Menu contains the branches to all sub-menus. All different features can be accessed from this Main
Menu.

1.1.2 Window Setup
This is where source, size, position, zoom, and crop can be modified per window. Once selected, the
choice of window for modification will appear. Window Setup affects the characteristics of the window
itself and not the image inside the window.
Source allows input signal to be assigned to a specific window. For example, the menu below shows that
DVI is assigned to window 1 and Video input is assigned to window 2.
Window Size gives the ability to change the horizontal and vertical sizes of a window.
Window Position gives the ability to independently change the horizontal and vertical positions of a
window. Note that to move a window, the size of that window must be smaller than the active area.

DIDO LT Installation Manual
15
Window Zoom gives the ability to proportionally change both the horizontal and vertical sizes of a
window.
Window Crop allows each of the edges of an image to be adjusted into the window to help reduce noise
specific to an input. Crop is specific to the current resolution of the input inside the window. It must be
saved into a profile in order for it to be automatically applied. If a new resolution is applied, crop must be
re-adjusted. Crop is best for video images that have noisy borders. If the arrow key is pressed once, the
value will change by one pixel. If an arrow is pressed and held for 2 or more seconds, the value will
change by 10 pixels instead.
Note: For Window Size, Window Position, and Window Zoom, there are 1000 points of accuracy. If the
arrow key is pressed once, the value will change by tenths of a percent. If an arrow is pressed and held
for two or more seconds, the value will change by 1 percent instead of tenths.
Video wall setup allows quick setup of a multiple monitor system. Enter the total number of columns and
rows as well as the row and column of the one that’s being setup followed by apply changes. The output
will be changed to the appropriate size. It is still necessary to account for the bezel size of the display
device by manually changing the zoom, size or crop. When done, make certain to save in a preset.

1.1.3 Input Setup
Input Setup allows a user to manually configure different connector inputs.
SVID: Auto, S-Video, and Video. If the image can not lock well due to poor sync, use the manual
selection.
DVI: Auto, Norm PC, Wide PC, and Video. The manual selection helps to set correct input timing such
as Video or PC. This will help the DIDO LT to better sync on an input.
RGB: Auto, Norm PC, Wide PC, and Video. The manual selection helps to set correct input timing such
as Video or PC. This will help the DIDO LT to better sync on an input.
RGB/YPbPr: RGBHV, RGsB, and YPbPr. Select the type of signal connected to the RGB input.
ADC Settings currently has phase control as the selection. It is used to reduce noise on the YPbPr input
due to the cable or other factors and to correct the phase of H/V syncs of RGB input.
1.1.4 Layout Setup
The Layout Setup menu determines the way the windows are positioned and how many windows are
displayed.

DIDO LT Installation Manual
17
Layout selects window layout from Single, PiP, and Dual
Stack Type selects the positions of windows 1 and 2 in Dual mode. The selections are Left-Right and Up-
Down.
Left-Right Dual Mode Up-Down Dual Mode
PiP Transparency sets the transparency level (16 levels) of the pip window when in PiP mode.
PiP Size adjusts the size of the PiP window from 0 - 100 percent with accuracy down to the tenths.
PiP Position adjusts the position of the PiP window from 0 - 100 percent with accuracy down to the
tenths.
Flip Setup changes the input image orientation with respect to the output. This allows for mirror images
to create new effects.

Horizontal Disabled Horizontal Enabled
1.1.5 Output Setup
Output timing for the DVI/RGBHV/YPbPr connector is selected here. Output type can also be modified
from this menu for the analog portion of the connector. The selections are RGBHV, RGsB, YPbPr, and
No Output.
HDCP Output gives the ability to always have HDCP enable or the DIDO will decide when to enable and
disable the HDCP.
Video settings adjust the brightness, contrast, saturation, and hue of picture output. All windows will be
affected when adjusted.
1.1.6 Preset Setup
This menu allows the saving and loading of up to 99 presets. To save or load a preset, select Load Preset
or Save Preset. Then change preset number to be saved or loaded. Press “SEL” to confirm changes. If it is
saving, the OSD will display “Preset is being saved”. Presets can take up to 2 seconds to load. So if only
simple switching sources is needed, use the keys or RS-232 commands for quicker changing of inputs.
Presets are great for a starting point when many things need to change at once as it stores everything such
output resolution, modes, input setup, video settings etc.

1.1.7 System Settings
This menu allows the selection of items which affect the overall DIDO LT operation.
Unit Address allows many DIDO LT units to be connected via RS-485. When connecting multiple DIDO
LT units via the RS-485, each unit must be addressed differently. This address will be used when
controlling via RS-232 from a control system or PC. In addition, the last unit in the chain must have
RS-485 Termination enable.
The IR remote is also addressable (see IR remote section) and if set to the same address as the DIDO LT,
it will control only that DIDO LT This feature is very useful when multiple DIDO LT units are present to
prevent inadvertently controlling other units.
Remote Query is a diagnostic tool used to check for any DIDO LT remote’s current address even if it is
not matched to the address of that DIDO LT unit.
OSD Setup turns on/off the Menu Transparency and OSD.
Menu Transparency allows the menu to blend with the background.
