Matrox Mga-G400; Display Features - Matrox Orion Installation And Hardware Reference

Matrox Orion 9
Orion features eight software-selectable input channels to
which you can attach up to eight CVBS, four Y/C, or two RGB
cameras and then grab from one of these cameras.
Matrox Orion includes three 256x8-bit programmable input
lookup-tables (LUTs) to remap the video stream.
Matrox Orion can accept an opto-isolated differential trigger
input or a TTL trigger input to capture the next valid frame or
field.

Matrox MGA-G400

Matrox Orion features the Matrox MGA-G400 controller. This
controller uses a 32-Mbyte frame buffer to store data for display
and for transfers to the Host. When in bus master mode, Matrox
MGA-G400 can perform transfers without requiring
continuous Host intervention.
The AGP version of the Matrox Orion board is capable of AGP
1X and 2X speeds, depending on the chipset in your computer.

Display features

The Matrox MGA-G400 uses a 32-bit wide, master AGP or PCI
Host interface, and includes two independent CRT controllers.
Matrox Orion uses the primary CRT controller for the main
display (VGA) output, and the secondary CRT controller as an
independent secondary (TV) display output.
Overlay capabilities Controlled by the MGA-G400 chip, Matrox Orion's 32-Mbyte
frame buffer is used to store both graphics and video data. The
MGA-G400 chip is capable of dynamically allocating both an
overlay and underlay frame buffer surface; these can be
combined by the controller to display a live video window on
your Windows desktop with non-destructive annotations.
Because of these capabilities, Matrox Orion supports MIL's
DirectDraw underlay-surface display architecture.
Matrox Orion can deliver a true color (32-bit) image display
with a 32-bit color overlay, for a completely true color display
at up to 1280x1024 resolution with a maximum vertical refresh
rate of 75 Hz; note that this is dependent on your monitor.
