We are no longer accepting applications for the NVIDIA Quadro SDI SDK since the same low latency video I/O can be achieved across a wide range of GPUDirect for Video enabled 3rd party I/O boards . Contact the I/O board vendors for access to their SDK and follow the included GPUDirect for Video examples. If you have any questions about legacy support for the NVIDIA Quadro SDI SDK, contact us at DVP-support@nvidia.com.
