Multi Video Overlay Card

The Mosaic is a PCI plug-in card which has been designed to  operate in conjunction with the Horizon 4VW-DIG and iH4 DIG graphics card. The Mosaic, when combined with the Horizon, provides up to 9 separate video  overlay windows. For systems that require more than 9 overlay windows, a second Mosaic card can be installed providing up to 18 separate windows.

Features:

• Up to 9 Video overlay windows on a single screen.
• Multiple Mosaic cards allowing up to 144 video  windows.
• Overlay windows can be randomly sized, overlapped and positioned anywhere on the Windows Desktop.
• Multi-Screen support, no position or size  restrictions.
• Mosaic supports up to 6 Horizon 4VW-DIG graphics adapters.
• Video overlay windows are updated in real time with zero CPU overhead.
• Multi-standard video support, PAL, NTSC, SECAM and  S-Video.
• Separate controls for brightness, contrast, colour and cropping.
• Window border selection and chroma keying.
• Mosaic user application program.
• Windows NT4, 2000 and XP driver support with an SDK for  custom applications.

•                                                

On Card Connectors
 

• 2 x 26 way D connectors mounted on the back panel  providing connection for video inputs.
• 2 x 40 way ribbon headers for connection to the Horizon  4VW-DIG adapters.
• On card jumper links provide selection of terminated or  un-terminated 75ohm video inputs. (27 links, 3 for each overlay)

Cables

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 Horizon 4VW-DIG.
M4H1-cable - Connects 4 Mosaic cards to 1 Horizon  4VW-DIG.
M2H4-cable - Connects 1 or 2 Mosaic cards to 1, 2, 3 or 4  Horizon 4VW-DIG.
M4H4-cable - Connects 4 Mosaic cards to 1, 2, 3 or 4 Horizon 4VW-DIG.
M2H6-cable - Connects 1 or  2 Mosaic cards to 1, 2, 3, 4, 5 or 6 Horizon 4VW-DIG.
M4H6-cable - Connects 4 Mosaic cards to 1, 2, 3, 4, 5 or 6 Horizon 4VW-DIG.

As stated, the Mosaic is shipped with the M2H4 cable set as  standard. If a different cable set is required, please specify your requirements  when ordering by quoting the Mosaic Model Number:

Mosaic Model Numbers                                                             

• Mosaic - Mosaic Card with M2H4-cable set (standard).
• Mosaic-xxxx - Mosaic card supplied with a specific  cable set (xxxx) for example Mosaic-M2H1.
• Mosaic-NRC - Mosaic card with no ribbon cable  set.

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 Horizons, (maximum of 4), in the system. This allows any Mosaic window to  be displayed anywhere on the desktop. Maximum screens = 16 and 36 video windows.

Method 2:

If more than 36 video windows or more than 16 screens are required, the wall can be arranged so that the windows  are displayed over part of the wall. Each Horizon card is configured to control a particular group of 4 screens using the Horizon registry settings. You can decide how many video windows are required for each group of 4 screens that will be controlled by the Horizon. For each Horizon, 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  Horizon card that you want the video overlays to operate over.

Rules for Connecting Mosaics...

• * Each Mosaic can be connected to a maximum of 6 Horizon  cards.
  * Each Horizon 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 Horizon card it is attached to.

The following examples show some of the  possibilities:

Example 1. Each Mosaic is connected to all  Horizon Cards (Method 1) * 1 to 6 Horizon cards - 1 to 24 screens * 1 to 4  Mosaic cards - 9, 18, 27 or 36 windows.

Example 2:

Mosaic cards are connected to a  single Horizon card (Method 2)

• * 6 Horizon cards - 24 screens.
  * 4 to 16 Mosaic cards - 36 to 144 video windows.

Example 3:

Mosaic cards are connected to a single Horizon card (Method  2)

• * 6 Horizon cards - 24 screens.
  * 6 to 16 Mosaic cards  - 54 to 144 video windows.

Example 4:

Each Horizon has a single Mosaic card connected to it with a further Mosaic connected to all Horizons. This example use both connection  Methods 1 and 2.

• * 6 Horizon cards - 24 screens.
  * 5 Mosaic cards - 45 video windows - 9 video windows per Horizon card = 36 windows (4 Mosaic cards) (Method 2) - 9 video windows over the entire wall ( 1 Mosaic card) (Method 1)

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:

6 Horizon 4VW-DIG cards = 24 screens
16 Mosaic cards =  144 video overlay windows.
