Streaming Everything with NVIDIA Rivermax

In 2020, many of us adopted a work-from-home routine, and this new norm has been stressing IT networks. It shouldn’t be a surprise that the sudden boost in remote working drives the need for a more dynamic IT environment, one that can pull in resources on demand.

Over the past few years, we’ve focused on the Media & Entertainment (M&E) market, supporting the global industry as it evolves from proprietary SDI to cost-effective Ethernet/IP infrastructure solutions. NVIDIA technologies are enabling M&E to take the next transformational step toward cloud computing, while meeting compliance with the most stringent SMPTE ST-2110-21 specification requirements.

On the journey to modernize M&E network interconnect, we introduced NVIDIA Rivermax, an optimized, standard-compliant software library API for streaming data. Rivermax software runs on NVIDIA ConnectX-5 or later network adapters, enabling the use of common off-the-shelf (COTS) servers for streaming SD, HD, and up to Ultra-HD video flows. The Rivermax-ConnectX-5 adapter card combination also enables compliance with M&E specifications, such as the SMPTE 2110-21; reduces CPU utilization for video data streaming; and removes bottlenecks for the highest throughput. It can reach 82 Gbps of streamed video with a single CPU core.

As our partners have rolled out new Rivermax-based, full-IP solutions rigorously tested in their labs, we’re excited to share the fruits of these collaborative investments in Rivermax 1.5, the latest release of the streaming library. Rivermax 1.5 includes key features and capabilities enabling performance boosts and quicker integrations. One of these new features allows Rivermax-accelerated applications to stream not only video, audio, and ancillary data but other data stream formats as well, enabling Rivermax accelerations and CPU savings in many new markets and applications:

  • Compressed video
  • Healthcare imaging (DICOM-RTV)
  • Cloud gaming
  • Autonomous car sensor streaming (video/LiDAR/RADAR)
  • And more

Another good piece of news is that Rivermax 1.5 recently passed the JT-NM Tested program (March 16 – 20, 2020), allowing for integration and interoperability with multiple other market vendors.
