NVIDIA Graphics-to-SDI
Using the SDI APIs
The SDI application programming interface allows OpenGL applications to have full and
exclusive control of the SDI output.
When the SDI output is under application control, you can view the SDI hardware status
using the NVIDIA Control Panel Send graphics to SDI ouput page.
• See the chapter “API Control” on page 47 for a description of the graphics ‐ to ‐ video ‐ out
API calls.
• Also, refer to the document
Programming the NVIDIA Quadro FX 4800/5800 SDI
for
instructions on using the APIs.
Using the Control Panel
When the SDI output is not being controlled by an application, the SDI software works on
top of existing applications, and the active workstation desktop or full screen application
display is automatically forwarded to the SDI video outputs. This is accomplished under
either Clone or Dualview mode.
In this mode, you can use the NVIDIA Graphics to SDI property page to
• Configure the external synchronization signal if needed.
• Specify the SDI signal format, output format, and then enable the SDI output.
For detailed instructions under Windows, see the chapter “Windows–Using the Graphics
to SDI Control Panel” on page 15 .
For detailed instructions under Linux, see the chapter “Linux—Using the Graphics to
Video Out Control Panel” on page 31 .
