Quantum Series Videowall Processing Systems • Introduction 11
Expansion options — Scenario 2
With the Quantum Elite 615, you have five spare card slots to which you can add more
output cards to provide more screens, or you can add more input cards to increase the
choice of sources.
NOTE: Increasing the number of full resolution source windows exceeds the real time
limit of the RAPT bus, so the Quantum uses its bandwidth management scheme.
Scenario 3 — Maximum number of video sources on a tiled display
Screen layout — Scenario 3
In this scenario, six UXGA (1600x1200) display devices create a 3x2 tiled display of
144 video source windows arranged in a 12x12 array. The total display size is 4800x2400
pixels, making each window approximately 133x100 pixels.
Figure 6. Example of the Maximum Number of Video Sources on a Tiled Display
Because each window is smaller than the native source resolution, the input card scales
each source down to the required size. This greatly reduces the amount of source data
to be transferred across the RAPT bus to the output card, allowing a large number of
sources to be displayed simultaneously in real time.
Hardware requirements — Scenario 3
• 3 output cards driving 6 UXGA screens
• 12 input cards providing 144 inputs
• A Quantum Elite 615 card frame
