NAB 2016: Game-Changing Performance of V-Nova PERSEUS Video Compression Validated by Research

V-Nova, a provider of video-compression solutions, has published the results of an independent evaluation of its V-Nova PERSEUS video-compression technology. The results demonstrate that the technology offers visually lossless compression for video contribution at compelling operating points: 1080i25 at 75 Mbps, 1080p50 at 150 Mbps, 2160p50 at 200 Mbps.

v-nova-logo-webDesigned and carried out by independent consultancy informitv, the evaluation methodology combines qualitative and quantitative examinations of sample material encoded using V-Nova PERSEUS. All the HD and 4K/UHD tests were performed live on P.Link 4K, V-Nova’s contribution encoder and decoder solution used for live coverage of this spring’s El Clasico football match and selected by Eutelsat for coverage of the European football championships in 4K/UHD.

The evaluations also show that high-dynamic-range images encoded with V-Nova PERSEUS deliver higher fidelity output without any compression overhead. Furthermore, 8K/UHD-2 format images of 7680×4320 pixels at 48 bits per pixel were visually lossless at 40:1 compression, which is equivalent to the data rate of uncompressed HD video.

“We were amazed by the claims for V-Nova PERSEUS, but the results of our rigorous evaluations speak for themselves,” said informitv’s Dr. William Cooper. “V-Nova PERSEUS compression proved visually lossless for UHD production applications at impressively low data rates, as confirmed by objective measurements. V-Nova can also deliver 4K high-dynamic-range video today, and V-Nova PERSEUS compression is already 8K-ready.”

Said V-Nova CEO/co-founder Guido Meardi, “We’re delighted that the independent evaluation by informitv showed that V-Nova PERSEUS is visually lossless for 4K contribution at these low bitrates. This confirms for potential users that our technology is ready today to provide a step-change in video-compression efficiency as well as being future-proofed through intrinsic support for HDR and 8K.”

V-Nova PERSEUS is a video-processing technology that addresses today’s video-delivery challenges. It redraws the traditional quality-bitrate curve, enabling operators to contribute video at both higher quality and a lower bitrate. V-Nova PERSEUS software closes the capacity gap for high-quality delivery to connected devices over existing networks.

White papers documenting the results of the qualitative and quantitative evaluations independently designed and conducted by informitv are available from the V‑Nova website.
