With over 70% of the global video market being dominated by live content, there is significant demand for a class of low-latency, high-volume interactive streaming applications such as watch parties, live shopping, online auctions, and social streaming.
The Alveo MA35D media accelerator delivers high channel density, with up to 32x 1080p60 streams per card, along with power efficiency and ultra-low-latency performance, both of which are critical to reducing the infrastructure costs now required for scaling such compute intensive content delivery.
According to AMD, compared to the previous generation Alveo U30 media accelerator, the Alveo MA35D delivers up to 4x higher channel density, 4x max lower latency in 4K and 1.8x greater compression efficiency to achieve the same VMAF score – a common video quality metric.
“We worked closely with our customers and partners to understand not just their technical requirements, but their infrastructure challenges in deploying high-volume, interactive streaming services profitably,” said Dan Gibbons, general manager of AECG Data Center Group, AMD. “We developed the Alveo MA35D with an ASIC architecture tailored to meet the bespoke needs of these providers to reduce both capital and operating expenses for delivering immersive experiences to their users and content creators at scale.”
The Alveo MA35D uses a purpose-built VPU to accelerate the entire video pipeline. By performing all video processing functions on the VPU, data movement between the CPU and accelerator is minimised, reducing overall latency and maximising channel density with up to 32x 1080p60, 8x 4Kp60, or 4x 8Kp30 streams per card.
The platform provides ultra-low latency support for the mainstream H.264 and H.265 codecs and features next-generation AV1 transcoder engines delivering up to a 52% reduction in bitrate for bandwidth savings versus a comparable software implementation5.
“AMD’s announcement is an exciting advancement of video acceleration for data centres and is an important step in building out a fully-fledged ecosystem to support royalty-free, high-definition video devices, products, and services,” said Matt Frost, Alliance for Open Media Chair. “Live streaming providers are looking for higher density, lower power, lower latency AV1 solutions and by addressing these, Alliance members such as AMD are helping facilitate AV1 deployment and overall adoption.”
The accelerator features an integrated AI processor and dedicated video quality engines designed to improve the quality of experience at reduced bandwidth. The AI processor evaluates content, frame-by-frame, and dynamically adjusts encoder settings to improve perceived visual quality while minimising bitrate.
Optimisation techniques include region-of-interest (ROI) encoding for text and face resolution, artifact detection to correct scenes with high levels of motion and complexity, and content-aware encoding for predictive insights for bitrate optimization.
Scaling high-volume streaming services requires maximising the number of channels per server while minimising power and bandwidth-per-stream. By delivering up to 32x 1080p60 streams per card at 1 watt per stream, a 1U rack server equipped with 8 cards delivers up to 256 channels to maximise the number of streams per server, rack or data centre.
The platform is accessible with the AMD Media Acceleration software development kit (SDK), supporting the widely used FFmpeg and Gstreamer video frameworks for ease of development.
Alveo MA35D media accelerators are sampling now with production shipments expected in Q3.
