Quantum Series Videowall Processing Systems • Introduction 10
Expansion Options — Scenario 1
On the Quantum Elite 615, you have three spare card slots to which you can add more
input cards, increasing the choice of sources. Alternatively, you can add output cards to
spread out the windows and increase their size.
Scenario 2 — Maximum number of full resolution video sources on a
tiled display
Screen layout — Scenario 2
In this scenario,12 UXGA (1600x1200) displays create a 4x3 tiled display with 48 video
source windows arranged in an 8x6 array. The total display size is 6400x3600 pixels,
making each window 800x600 pixels.
Figure 4. Example of Tiled Full Resolution Video Sources on a Tiled Display
Because each window is larger than the native source resolution, each source is
transferred across the RAPT bus at its native resolution and then scaled up to the required
size by the output card.
Hardware requirements — Scenario 2
The hardware requirements for scenario 2, video sources on a 4x3 tiled display, are:
• 6 output cards (driving 12 UXGA screens)
• 4 input cards (providing 48 source inputs)
• A Quantum Elite 615 card frame
System capacity — Scenario 2
Figure 5. System Capacity for Scenario 2
The limit of 48 real time source windows is imposed by the available RAPT bandwidth
and the available screen space. This assumes that all sources are using single-field
deinterlacing.
