Abstract: Graphics processing unit (GPU) installations in post-production and broadcast facilities require video to be sent remotely conforming to the SMPTE ST 2110 standards for plug-and-play device connectivity. Furthermore, in such facilities, workstations are now being virtualized and hosted in the data center with what would have previously been a physically attached serial digital video (SDI) reference display replaced by an Internet Protocol (IP) network connection. We present a SMPTE ST 2110 virtual network-attached reference display adapter using commercial off-the-shelf (COTS) hardware that presents the GPU and network interface card (NIC) as a display on the computer workstation desktop. Color-accurate rendered video frames are transmitted directly from GPU device memory. Alignment of the GPU display of the rendered frame and the synchronization of the audio, video, and ancillary data streams are maintained by precision time protocol (PTP). Advanced Media Workflow Association Networked Media Open Specifications (AMWA NMOS) integration permits the discovery and registration of the virtual network-attached reference display adapter as a source node on the media network such that it can be remotely managed and controlled by software greatly simplifying the administration compared with a physically connected display and associated cables. Content creation applications send ST 2110-compliant video, audio, and ancillary data flows on the media network from a virtualized computer workstation desktop without the cost of directly integrating ST 2110 transmission capabilities.

bio
Thomas True is a senior applied engineer for professional video and image processing at NVIDIA’s Enterprise Solutions Group, Santa Clara, CA. In this role, he works at the intersection of video I/O and the graphics processing unit (GPU) where he focuses on the integration of GPU and networking technologies into broadcast, video, and film applications ranging from previsualization to post-production and live-to-air. Before joining NVIDIA, he was an applications engineer at SGI, Mountain View, CA. He has an MS degree in computer science from the Graphics Laboratory, Brown University, Providence, RI, and a BS degree from the Rochester Institute of Technology, Rochester, NY. He has spoken on the application of the GPU in broadcast and post-production at the SMPTE Annual Technical Conference and SMPTE Section meetings.
