Introduction
The Mosaic is a PCI plug-in card which has been designed to operate in
conjunction with the Horizon 4VW-DIG and the iH4-DIG
graphics card. The Mosaic card, when combined with the Horizon 4VW-
DIG and iH4, provides up to 9 separate video overlay windows.
For systems that require more than 9 overlay windows a second Mosaic
card may be installed providing up to 18 windows.
The Mosaic is supplied with driver software for Windows® 2000 and XP.
The Wall Control application program is provided enabling users to
control the video overlay windows or, for users who wish to control the
Mosaic card from their own software, an SDK is also provided.

Unpacking
Your packing box should contain the following items:
• The Mosaic PCI plug-in card.
• 2 x multi-way splitter cables. (BNC 16 - Cable)
• 2 x M-cable-4s. (40 way Ribbon Cables)
Notes:
All plug-in cards are static sensitive and are packed in anti-static
materials. Please keep the card in its packaging until you are ready
to install.
We recommend that you do not discard the packing box until you
are completely satisfied with the Mosaic, and it is fully installed and
working correctly. We also recommend that you make note of the
serial number of the card in a prominent place before you plug the
card into the computer. This should hasten any query should you
need to contact our Technical Support Department. The serial
number is displayed on the card and the box label.

Installing the Mosaic Card
Note:
You are likely to need a flat blade and a Phillips head screwdriver
for the installation so please ensure you have these to hand before
you begin.
• Power down your complete system (including peripherals) at the
PC and the main power supply.
• Disconnect all the cables connected to the PC, noting the positions
for correct reconnection after the Mosaic card is installed.
Carefully remove the cover from your PC.
• Locate an available PCI slot to install your Mosaic card preferably
next to your Horizon 4VW-DIG or iH4-DIG. You may need to
remove the expansion slot cover and screw, please retain these
for future use.
• Holding the card firmly by its top edge at each end of the card’s
length, slide it into the slot.
• Using the retaining screw, secure the bracket to the back panel.
• Replace the cover on your PC

Installing the Mosaic with the Horizon and iH
Card
The Mosaic is connected to the Horizon 4VW-DIG or iH4-DIG
cards via inter-card ribbon cables, enabling the video overlays to select
upto 9 possible video sources. The Mosaic supports up to 8 Horizon
4VW-DIG or 8 iH4-DIG cards
• Install and configure all the required Horizon 4VW-DIG or iH4-DIG
cards in the system, carefully following the installation instructions.
Ensure that your multi-screen system is working correctly before
installing the Mosaic card.
• Install the Mosaic card as described in Installing The Mosaic Card
• Once the Mosaic is installed it can be connected to the Horizon
4VW-DIG or iH4-DIG cards in the system.
Connect the 2 x 40 way ribbon cables from the Mosaic card to the
Horizon 4VW-DIG or iH4-DIG cards. The Mosaic card should be
connected to one end of the ribbon cable. The headers on the Mosaic
cards are marked J6 and J7 and should be connected to the graphics
cards as follows:
Connect the J6 header on the Mosaic to the J7 headers on the graphics
card.
Connect the J7 header on the Mosaic to the J8 headers on the graphics
cards.
The illustration on the next page details the location of the headers on
each of the cards:
8

Note:
It is imperative that the Jumper Link (J11) on the Graphics card is
removed from all the cards except the last one, the last one being
the card located furthest away from the Mosaic card. This provides
the clock termination for digital video bus supplied by the Mosaic
card.
The header J5 located on the Mosaic card is for factory use only.
Do not connect to this header.
There are numerous ways in which the Mosaic Card can be connected to
the graphics card, the basic rules are:
• The Mosaic will connect upto a maximun of 8 cards. The Mosaic
video window will only display on the screens driven by the
graphics cards it is connected to.
9

The illustrations on the next page demonstrate the simple and most
common arrangements made with the Mosaic.
There are many variations with many options to display the Mosaic video
windows. The maximum possible would be 8 graphics cards and 32
Mosaic cards, this would provide a total of 288 Mosaic video windows
and 32 displays. Each graphics card would be connected to 4 Mosaic
cards offering 36 video windows for each group of 4 displays.
This configuration would give the following display option:
• 9 Mosaic overlay displayed anywhere across 12 screens.
10

This configuration would offer the following display option:
• 18 Mosaic overlays displayed anywhere across 12 screens.
Note: Overlay windows from different Mosaic cards cannot be
displayed on the same screen.
Enabled outputs
Each Mosaic card has 4 outputs, up to 9 Mosaic windows can be
displayed through each card. When connecting more than one Mosaic
card, each output has to be connected separately otherwise the Mosaic
video windows will not be displayed.
If the system has 4 Mosaic cards connected to 4 graphics cards only one
output from each Mosaic card header can be connected. The illustration
below shows how this configuration is connected.
11

Connected this way the outputs from each Mosaic card are as follows:
• Mosaic Card 1 - Output 1
• Mosaic Card 2 - Output 2
• Mosaic Card 3 - Output 3
• Mosaic Card 4 - Output 4
12

How To Connect Video Inputs
Each video input is channeled to a specific window, each video window is
displayed by selecting a specific window from the application software,
therefore it is important that the video inputs are connected correctly.
The windows each have three inputs that can be utilised as follows:
• Composite A / Luma
• Composite B
• Chroma
If you wanted to connect a specific composite input to window 9 then you
would connect the input to the BNC cable, number 1 on the bottom
splitter cable.
If you wanted to connect an S-Video input to window 4, then you would
connect the 2 S-Video inputs into the BNC number 7 and 8 (Chroma and
Luma) on the top splitter cable.
The following table describes how to connect the video inputs to the
specific Mosaic video windows and which jumper link on the Mosaic card
provides the 75ohm termination for each input. The links should be fitted
to apply termination. (All links are fitted as standard.)

When installing multiple Mosaic cards in your machine it is
important that the jumper links LK28, LK29, LK30 and LK31 located
on the Mosaic cards are configured correctly for the number of
Mosaic cards in use.

How To Get The Best Quality Video Windows
From the Mosaic
Example 1 shows a single screen with 3 Mosaic windows, shown in
yellow.
The software analyses the position and size of the Mosaic Window and
allocates each window to an overlay. Mosaic supports up to 4 overlays
but there can be only one overlay covering any particular screen.
In this example a single overlay would be generated that bounds the 3
Mosaic windows. The overlay size and position is shown as a broken line
(-----). In the following examples any window shown in YELLOW
indicates GOOD QUALITY.
Windows shown in Red indicates POOR QUALITY. The trick for best
quality is to position the windows such that the bounding overlay is as
small as possible.
Note: You cannot display 2 or more overlays on the same screen
and there is a maximum of 4 overlay’s available.
Example 1
Example 2
In this example a 4th Mosaic window is now opened on a 2 x 2 wall. The
new window is large and touches the same screen as the 3 small
windows. This creates poor quality overlays.
Mosaic can only use one overlay to produce this layout because 2
overlays cannot cover the same screen. The overlay has to bound all 4
windows and then be up-scaled to cover the screen area. The video
quality for the large window shown in yellow will be good. The 3 smaller
16

windows have to be down-scaled because they occupy a small part of the
overlay and so quality will degrade.
To improve the quality of the 3 small Mosaic windows, reposition the
large window so that it does not have any contact with the same screen
as the 3 small Mosaic windows.
The illustration below shows that by repositioning the large yellow window
Mosaic is allowed to use 2 overlay outputs and maximise the quality of
the 3 small windows and maximises a second overlay for the large
window.
17

Example 3
(4 x 3 wall with 1 Mosaic card and 9 windows)
Poor layout - Only 1 overlay can be used because the large window
touches all screens
By repositioning the large window so that it touches fewer screens,
Mosaic can allocate more overlays and quality will improve.
All 4 overlays can be used here dramatically improving the quality of the
small windows on the left of the wall. However, although the small
windows on the right are improved, they are still not ideal
18

If the large window is now repositioned such that it touches even fewer
screens then the quality will improve further. Also, move the window on
screen 5 nearer to the window on screen 1.
The 4 overlays are all used making best use of each overlay. All
windows should be of good quality.
This layout is almost the same as the starting layout but the video quality
has greatly improved.
Always try and make the Mosaic window as large as possible
relative to the size of the overlay that bounds the window(s).
The resolution of each Mosaic window is the ratio of it’s horizontal
and vertical size when compared to the size of the overlay that
bounds the window. The resolution of the overlay is always 768 x
567 so if the Mosaic window is tiny in proportion to the overlay, the
resolution of the Mosaic window will be small and of low quality.
Using more than 1 Mosaic Card.
The same rules apply when you use more than 1 Mosaic card, however,
the number of overlays for each card reduces, so this means that greater
care is required with window positioning to obtain optimum quality. Also,
video windows from different Mosaic cards cannot be placed on the same
screen.
• 2 Mosaic Cards = 2 overlays per card.
• 4 Mosaic cards = 1 overlay per card.
Example showing 2 Mosaic cards on a 4 x 3 wall
A = Window from Mosaic card A
19

B = Window from Mosaic card B
The layout is not possible because the overlay bounding areas overlap.
The windows shown in purple will not display any video. Also, because
the large windows touch the same screen as the smaller windows, quality
will be bad. With this layout each Mosaic cards would generate only 1
overlay.
In order to be able to display all the windows first change the
window order as follows:
Now each Mosaic card will generate a single overlay containing all the
windows. Quality is still bad because the large windows touch the top
row of screens. This stops the Mosaic cards from being able to use their
second overlay.
