Beamr HEVC Encoder Image Science AMD EPYC 7742 Solution Brief

Beamr serves the world's top MSOs and streaming video service providers as the industry’s top designer of content-adaptive encoding and video optimization solutions that enable superior video quality, excellent CPU performance, and superior bitrate efficiency for managed services, streaming video distributors, broadcasters and video streaming platforms. Backed by 44 patents, Beamr's perceptual optimization technology has been integrated with our HEVC and H.264 software video encoders. CABR (Content-Adaptive Bitrate) is a innovative rate-control mode that enables guaranteed quality to be delivered at very low bitrates. Founded in 2009, Beamr investors include Verizon Ventures, Eric Schmidt backed Innovation Endeavors, and Disruptive.

Beamr solutions provide up to a 35% network reclamation by reducing video files as much as 50% with Beamr 4x and Beamr 5x H.264 and HEVC CABR enabled content-adaptive encoders. Beamr provides the best video quality at the lowest bitrate for mobile operators and public networks and managed service platforms seeking to reduce video bandwidth utilization on the network backbone and edge.

Beamr's perceptual quality measure is based on a proprietary, low complexity, highly reliable, perceptually aligned quality metric that is covered by 33 granted patents. The existence of this special quality measure makes possible the task of controlling a video encoder to obtain an output clip with maximal compression of the video input while maintaining the original video resolution, format and visual quality. This feat occurs by adjusting the compression level of each frame in the video sequence so that it is compressed to the maximum while producing a perceptually identical result.

The Beamr quality measure has been in development since 2009. After years of refinement, and subjecting it to the strict requirements and testing of ITU BT.500 which is an International standard for validating image quality, we were able to confirm that there is a sufficiently high correlation of our quality measure with subjective results. The Beamr quality measure takes into account temporal artifacts. Since it is not sufficient to ensure only at the frame level that degradation has not been introduced - it is also necessary to preserve the quality of the video's temporal flow. If you view a video encoded using the VBR rate-control and a video encoded with the CABR rate-control side-by-side, they will appear identical to the human eye under normal viewing conditions. This is a secret to how the process is able to guarantee image quality.

As the next step in the development of more info CABR, Beamr demonstrated at NAB 2019 silicon accelerated CABR by showing integration with the Intel Media SDK. Silicon accelerated CABR allows Beamr to move closer to the original vision of optimizing the network and bringing newfound bandwidth savings. The Beamr CABR SDK enables video engineers to utilize the efficiency of silicon encoders so that they can create massively scalable consumer device, cloud, and edge encoding solutions which balance encoder density and performance, with bitrate efficiency.
