1 Introduction
The SPLITMUX-SVDVI-2 (SPLITMUX) is a high quality video processor engine. The
SPLITMUX-SVDVI-2 supports advanced functionality such as video format /scan rate
conversions, audio effects, 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 SPLITMUX 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, Moirécancellation, color correction,
adaptive flesh tone adjustments, image zoom & shrink.
•The powerful Rotation / 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
•Includes audio propagation delay compensation to properly sync with input video
•Internal Event Scheduler with Real Time Clock allows Rotation Engine special effects to be
scheduled locally and among SPLITMUX units when connected via the RS-485 bus

Key Description
Side A/B
DVI,
RGB,
VIDEO
The three source keys (section “A”) will select the source to be displayed on the
screen. (Section “B”is not used for SPLITMUX-SVDVI-2.) In Single mode, the keys
select the source immediately. In Dual mode a dialog will appear asking for window
selection.
P1-P4 Preset keys (pg. 18) make the usability of the SPLITMUX-SVDVI-2 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.
7.2 Menu Structure
The menu system allows a user to control various configurations of the SPLITMUX
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 detail in the subsequent chapters.
7.2.1 Main Menu
Main Menu contains the branches to all sub-menus. All different features can be accessed from
this Main Menu.

7.2.2 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.

SPLITMUX-SVDVI-2 DUAL SCREEN SPLITTER
14
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.
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.

SPLITMUX-SVDVI-2 DUAL SCREEN SPLITTER
15
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.
7.2.3 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 SPLITMUX 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 SPLITMUX 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.

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 or back to back images in rotated modes to create new effects.
Horizontal Disabled Horizontal Enabled
7.2.5 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 SPLITMUX will decide when
to enable and disable the HDCP.
