SDI Application Programming Overview 

Application programming of the NVIDIA Quadro FX 4000/FX4500 SDI consists of two 
principle parts–device control and data transfer. 

• Device control handles the hardware configuration as well as the starting and stopping 

of data transfers.

This chapter covers the APIs related to data control. 

• Data transfer is the sequence of operations that send graphics data to the video device 

for output.  

Device control is handled by the NvGvo API, described in this chapter.

Data transfer operations are performed by the OpenGL extension 
WGL_NV_video_out.

Device control is handled by the NV-CONTROL X extension, described in this 
chapter.

Data transfer operations are performed by the OpenGL extension 
GLX_NV_video_output.
