A London based company says its new codec can be two of three times as more efficient than the current industry leading compression standard, H.265/HEVC.

The company, V-Nova, says its Perseus codec has been shown in testing to have compression gains of two or three times compared to leading standards such as H.264/AVC, H.265/HEVC and JPEG2000.

The codec, which has been designed with 4K/UHD in mind, but will scale down all the way to even low (125 Kbps) bitrate encodings, for encoding standard definition content. The company claims that "good quality" UHD can be encoded using a bitrate as low as 4 Mbps (as a comparison, Netflix's 4K content streams at around 15 Mbps).

V-Nova says one potential application of its highly efficient codec would be WiFi sharing of 120fps 4K content.

"With PERSEUS we are able to shift the entire bitrate-quality curve toward the mass population, offering UHD quality at HD bitrates, HD at SD bitrates, and SD video at audio bitrates. This allows our partners to differentiate their products, increase market penetration, and provide new services. In particular, PERSEUS makes 4K commercially viable at scale, enables HD over 3G/4G mobile networks and makes video available to millions who do not yet have it. Most importantly, PERSEUS achieves this within currently available bandwidth and infrastructure," states Guido Meardi, CEO & Founder, V-Nova. "This guarantees rapid, seamless deployment and an extremely high return on investment."

V-Nova says it has been working with Broadcom, the European Broadcasting Union, Hitachi Data Systems, Intel, and Sky Italia on rolling out its Perseus technology.
