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 evaluation methodology designed and carried out by independent consultancy informitv 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 already used for live coverage of the El Clasico football match and selected by Eutelsat for coverage of the European football championships in 4K UHD.
The results demonstrate that V-Nova PERSEUS compression is visually lossless for video contribution at compelling operating points:
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 high-definition video.
“We were amazed by the claims for V-Nova PERSEUS but the results of our rigorous evaluations speak for themselves,” said Dr William Cooper of informitv. “V-Nova PERSEUS compression proved visually lossless for ultra-high-definition 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.”
Guido Meardi, V-Nova CEO and Co-Founder, added: “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 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.
