Scenario 1 – Maximum number of video sources on a single screen
Screen Layout
A single UXGA display device is used to display 64 video source windows arranged as an 8x8 array.
The total display size is 1600x1200 pixels, making each window 200x150 pixels.
Because each window is smaller than the native source resolution, each source is scaled down to the
required size by the Input Card. This greatly reduces the amount of source data needing to be
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
1 Output Card (only one output channel is used to drive a single UXGA screen)
6 Input Cards (providing 72 source inputs – only 64 can be viewed simultaneously)
An ES3301-2 or ES3302 & 3304 Card Frame.

RAPT Bandwidth
Rectangulation
ES3301 ES3302
The limit of 64 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 de-interlacing. Using three-
field de-interlacing will double the amount of source data but the real-time RAPT limit will never be
exceeded
Expansion Options
If you are using the ES3301-2 Card Frame there are 8 spare card slots, so you could add a second
Output Card and five more Input Cards to create a second display also showing 64 sources, giving
128 in total.
Alternatively, you could just add further Input Cards to increase the choice of sources available for
display.
