Scenario 1 — Maximum number of video sources on a single screen
Screen layout — Scenario 1
In this scenario, a single 1600x1200 display device displays 128 video source windows.

Example of a Single 1600x1200 Display Showing the Maximum
Number of Windows Possible on One Screen
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
transferred across the RAPT bus to the output card and allows a large number of sources
to be displayed simultaneously in real time.
Hardware requirements — Scenario 1
The hardware requirements for scenario 1, 128 inputs displayed on one screen, are:
•
1 output card (Only one output channel is used to drive a single 1600x1200 screen.)
•
11 input cards, providing 132 source inputs. (Only 128 can be viewed simultaneously.)
•
A Quantum Elite 615 (15-card) card frame

System Capacity for Scenario 1
The limit of 128 source windows is imposed by the rectangulation limit of the output card.
All sources are displayed in real time.
RAPT bandwidth usage assumes that all sources are using single-field deinterlacing.
Using three-field deinterlacing doubles the amount of source data without exceeding the
real time RAPT limit.
