NVIDIA Graphics-to-SDI
Software Setup
The NVIDIA SDI software lets you specify the
• SDI signal format
• Color formats
• Synchronization method
• Gamma correction
Graphics-to-SDI functionality can be set up and controlled in two basic ways—using the
NVIDIA control panel or using the NVIDIA SDI API.
Using the SDI APIs
The SDI application programming interface allows OpenGL applications to have full and
exclusive control of the SDI output. This is also known as extended mode.
When the SDI output is under application control, you can use the NVIDIA
Graphics to
SDI
property page to view the SDI hardware status.
• See the chapter
for a description of the graphics-to-video-out
API calls.
• Also, refer to the document
Programming the NVIDA Quadro FX 4000 SDI
for
instructions on using the API.
Using the Control Panel
When the SDI output is not being controlled by an application, you can use the NVIDIA
Graphics to SDI
property page to
• Specify the SDI signal format, output format, and then enable the SDI output.
• Configure the external synchronization signal if needed.
This is also known as transparent mode. In this mode, the SDI software work on top of
existing applications, and the active workstation desktop or full screen application
display is automatically forwarded to the SDI video outputs.
See the chapter
“Using the Graphics to SDI Control Panel” on page 11
for detailed
instructions on using the
Graphics to SDI
property page.
