Quantum Series Videowall Processing Systems • Introduction 5
• USB port — Two USB ports are provided to access image files on a USB flash drive
or to connect a USB keyboard and mouse to access the Quantum Control Panel.
• Motion adaptive deinterlacing — The SDI input card provides motion adaptive
deinterlacing for NTSC, PAL, and 1080i input signals. Film mode detection is provided
to properly deinterlace content originating from film.
Functional Overview
The Quantum can display a large number of sources in real time on a target display.
This section gives an overview of the features and functions that can affect the system
performance. The following key factors can affect system capabilities:
• Number of input and output card slots — The number of input and output
cards determines how many video inputs and display outputs are available. The
Quantum Elite 615 card frame can accommodate up to 15 cards, while the Quantum
Elite 408 can have up to 8 cards. The Quantum Connect has 4 input cards and 1
(Connect 82) or 2 (Connect 84) output cards.
• RAPT bandwidth — The RAPT (Real-time Asymmetric Packetized Transfer) bus
carries video and RGB source data between the input and output cards. It can
carry the equivalent of 48 full-resolution standard definition video sources in real
time. If more data needs to be transported, a scheme of bandwidth management is
implemented.
•
Rectangulation limit
— The maximum number of windows that can be displayed
by a single output card is 128 rectangles per output channel pair (windows can be
displayed on one or both channels).
RAPT Bus for Source Transfer
The RAPT is a high-speed data bus used exclusively for the transfer of digitized video
and RGB source data between the input and output cards. It is also used to carry any
QGE 100 source signals to the output cards.
Real time performance
The RAPT bus delivers data in real time. This means that it is able to display a source
at its full temporal resolution, maintaining the same scan rate as the original source
without dropping any fields or frames. The RAPT bus remains operational if an operating
system crash occurs, allowing crucial source content to be maintained on the target
display. The RAPT bus can carry the equivalent of 48 full-resolution, full-motion standard
definition video sources in real time, using 4:2:2 sampling and single-field deinterlacing, as
summarized in the
table on the next page.
