Since it emerged not so long ago V-Nova’s PERSEUS has shaken up the video delivery market and its claims to be a ‘game-changer’ have now been independently verified.
In an independent evaluation, independent consultancy informitv found that V-Nova PERSEUS compression was visually lossless for video contribution at key operating points including 1080i25 at 75 Mbps; 1080p50 at 150 Mbps and 2160p50 at 200 Mbps. In addition, it found that High Dynamic Range (HDR) images encoded with V-Nova PERSEUS deliver higher fidelity output without any compression overhead. 8K UHD-2 format images of 7680×4320 pixels at 48 bits per pixel were also found to be visually lossless at 40:1 compression, which is equivalent to the data rate of uncompressed high-definition video.
The test combined qualitative and quantitative examinations of sample material and all the HD and 4K Ultra HD tests were performed live on P.Link 4K , V-Nova’s contribution encoder and decoder solution already used for key sports events in Europe and li and selected by Eutelsat for coverage of the European football championships in 4K/Utra HD.
“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.”
