10 Chapter 1: Introduction
When grabbing video in SDI format, the data does not get converted. Standard
definition (SD) video input is in YCbCr601; high-definition (HD) video input
is in YCbCr709.
Display features
Matrox Orion HD can output video (the operating system’s desktop) to four
independent display devices simultaneously. These devices can be either digital
(DVI-D or SDI) or analog output devices, depending on the connector to which
they are connected. The video outputs are not only independent from each other,
but are also independent from the video inputs for maximum configuration
flexibility. The video outputs can be used to display an extended Windows desktop
or the Windows desktop and an exclusive display. However, to grab with the
Matrox Orion HD board, one of the board’s outputs must be used to display the
Windows desktop; otherwise, the Matrox GPU won’t be initialized properly and
won’t be available to control the grab. The table below summarizes the supported
standard display resolutions:
Two of the video outputs can be output in SDI format using a multi-rate serializer.
The other two video outputs can be output in RGB analog format or in DVI-D
format using a multi-format transmitter.
