NVIDIA introduced today NVIDIA GPUDirect for Video, a technology that enables application developers to deliver higher quality, more realistic on-air graphics – or take faster advantage of the parallel processing power of the GPU for image processing – by permitting industry-standard video I/O devices to communicate directly with NVIDIA professional Quadro and Tesla graphics processing units (GPUs) at ultra-low latency.
NVIDIA GPUDirect for Video technology is the fastest, most deterministic way to get video to the GPU for processing, enabling leading video I/O board manufacturers to take advantage of the programmability of the GPU. With GPU Direct for Video, the video I/O card is fully synchronized with the GPUs, eliminating CPU overhead and, most importantly, dramatically reducing latency.
“NVIDIA and our partners are redefining what’s possible in real-time video production,” said Greg Estes, industry executive, Media & Entertainment, NVIDIA. “Enabling lower latency solutions for processing real-time video streams will benefit not just those working in broadcast and production facilities, but also applications in manufacturing, healthcare and government agencies.”
Historically, broadcasters and video production professionals had to contend with delays of as many as ten frames – an amount easily visible to the eye - when transferring video from a video I/O device to a GPU, because the two devices could not communicate directly with one another to ensure synchronization. This required application developers to manage complex buffering schemes, leading to unnecessary CPU overhead and increased latency. Most importantly, these delays in aggregate significantly raised the cost and complexity of larger broadcast productions.
“AJA is supporting NVIDIA's new capability with our latest generation of video I/O products,” said Nick Rashby, President, AJA Video Systems. “This will allow developers whose apps support AJA video I/O products to take better advantage of the power of NVIDIA Quadro and Tesla GPUs, resulting in low-latency access for both graphics compositing and general purpose processing using CUDA or OpenCL, with all the I/O and performance they depend on from AJA.”
“Blackmagic Design is excited to support the new NVIDIA GPUDirect for Video technology being announced at IBC 2011,” said Grant Petty, CEO of Blackmagic Design. “NVIDIA and Blackmagic share a common vision to build a tightly-integrated platform for high-performance, low-latency video and graphics processing. Our customers in both broadcast and post-production industries will see tremendous benefits in the future by combining the processing power of NVIDIA Quadro and Tesla GPUs with our desktop video solutions.”
“DVS is known for developing the highest quality video boards in the market,” says Juergen Heger, senior product manager at DVS Digital Video Systems GmbH. “In real-time production environments, the latency between GPU and SDI is a critical point for our customers. Our famous, longstanding SDK now includes NVIDIA GPUDirect for Video. Our hardware solutions directly communicate with NVIDIA professional Quadro and Tesla GPUs without noticeable delay, which is ideal for applications like compositing, live graphics or real-time video-processing.”
“Matrox DSX Developer Products are renowned among broadcast equipment manufacturers for high performance I/O hardware, a comprehensive SDK, and outstanding applications engineering support,” said Alberto Cieri, senior director of sales and marketing from Matrox. ”Our collaboration with NVIDIA on their GPUDirect for Video technology for Quadro and Tesla professional GPUs will further enhance our OEM customers’ broadcast graphics system performance.”
“Vizrt is the market leader in broadcast graphics because of our long reputation for delivering innovative new solutions to our broadcast customers,” said Gerhard Lang, chief engineering officer, Vizrt. “We’ve been recommending NVIDIA Quadro as our GPU of choice for many years because of the quality and reliability of these solutions. With NVIDIA now working in partnership with video I/O manufacturers, we anticipate lower latency solutions with more I/O options, enabling higher quality and more detailed graphics for our customers worldwide.”
NVIDIA GPUDirect for Video technology will further advance the growing adoption of GPUs in film, live broadcast, and video production. Companies such as 3Ality Digital, Adobe, AJA, Autodesk, Avid, Binocle, Blackmagic Design, Brainstorm, Chyron, DVS, GenArts, MainConcept, RT Software, Quantel, Sony, The Foundry, Vizrt plus a growing number of application developers are already using GPU computing to accelerate their applications.
With the new NVIDIA GPUDirect for Video solution being unveiled at IBC 2011, video I/O manufacturers, companies who make their own proprietary hardware, and even companies making video switchers will be able to take advantage of these sub-frame, low latency transfers in their own SDKs and commercial solutions for no additional cost.
