Mosaic
Nine
Channel Video Input Card
The
Mosaic is a PCI plug-in card which has
been designed to operate in conjunction
with the
Datapath
iH4-DIG graphics card. The Mosaic, when
combined with the iH4-DIG, provides up to
9 separate video overlay windows.
For systems that require more than 9
overlay windows, up to 4 Mosaic cards can
be installed giving a total of
36 video windows.
When
using the Mosaic card, each video window
can display one of two possible video
inputs, these two inputs are dedicated

Multiple
Mosaic Cards
For
systems that require more than 9 overlays,
multiple Mosaic cards can be installed.
There are many possible configurations
with two methods of connecting Mosaic?s to
Horizon cards.
Method 1:
Each Mosaic (maximum of 4), is
connected to all iH4-DIG, (maximum of 8),
in the system. This allows any Mosaic
window to be displayed anywhere on the
desktop. Maximum screens = 32 and 36 video
windows.
When
the MBM-H2
or MBM-H4
is used in the system this allows up to 8
iH4-Dig cards to be used in the system.
Maximum screens = 32 and 36 video windows.
Method
2:
If more than 36 video windows or more than
32 screens are required, the wall can be
arranged so that the windows are displayed
over part of the wall. Each iH4-DIG card
is configured to control a particular
group of 4 screens using Wall Control
software.. You can decide how many video
windows are required for each group of 4
screens that will be controlled by the
iH4-DIG. For each iH4-DIG, connect up to 4
Mosaic Cards, this allows you up to 36
video windows for each set of 4 screens.
If some video windows are required to be
displayed over more than 4 screens or need
to be moved over more than 4 screens, then
the Mosaic cards can be connected to each
iH4-DIG card that you want the video
overlays to operate over.
Rules
for Connecting Mosaics:
-
Each
Mosaic can be connected to a maximum
of 8 iH4-DIG when using the MBM.
-
Each
iH4-DIG can be connected to a maximum
of 4 Mosaic Cards.
-
Video
overlays from a particular Mosaic card
can only appear on the screens driven
by the iH4-DIG card it is attached to.
Restrictions:
- The
maximum number of video windows on a
single screen is 9.
- Video
windows from separate Mosaic cards
cannot be displayed on the same screen.
Maximum
Configuration:
- 8
iH4-DIG cards = 32 screens (using the
MBM-H4)
- 16
Mosaic cards = 144 video overlay
windows.
Cables/Accessories
As
standard the Mosiac cards are shipped with
the M2H4 cable set and 2 x 16 way BNC
Splitter Cables.
Due
to the many configurations possible with the
Mosaic card, various cable sets are
available to order:
Cable
Sets
M2H1-cable
- Connects 1 or 2 Mosaic cards to 1 iH4-DIG.
M4H1-cable - Connects 4 Mosaic cards
to 1 iH4-DIG.
M2H4-cable - Connects 1 or 2 Mosaic
cards to 1, 2, 3 or 4 iH4-DIG.
M4H4-cable - Connects 4 Mosaic cards
to 1, 2, 3 or 4 iH4-DIG.

Mosaic
Buffer Modules
If
you require more than 4 iH4-DIG cards to be
connected to your Mosaic cards then by
adding the Mosaic Buffer Module (MBM) to the
M2H4 or M4H4 cable sets, you can increase
the number of iH4-DIG cards to 6 or 8
respectively.
The
MBM-H2 and MBM-H4 have a small PCB that is
attached to the J3, J7 and J8 headers on the
iH4-DIG enabling 6 or 8 cards to be conected
to your Mosaic cards.
MBM-H2
The
diagram below illustrates how the MBM-H2 is
used with 4 x Mosaic and 6 x iH4-DIG
MBM-H4
The
diagram below illustrates how the MBM-H4 is
used with 2 x Mosaic and 8 x iH4-DIG.
