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 contro
l 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.
Under WindowsXP
•
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.
Under Linux
•
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.
