Perseus and Perseus-2 are software-centric codecs for video compression that provide an alternative to H.264, HEVC and VP9 although Perseus can be used in parallel with these codecs.
The company has had successful deployments with Sky Italy and Thai Communications and claims that Perseus-2 provides a 20 to 30 percent improvement over Perseus to address a number of bottlenecks in IP video delivery.
Perseus has also been written with energy efficiency as a priority so that it can provide the necessary performance without needing more servers to cope with the scaling of image resolution.
For broadcasters that switch to Perseus the result will be more than 50 percent saving in the number of servers needed for encoding; a more than 70 percent saving in bandwidth costs; and a more than 70 percent saving in storage costs, V-Nova claimed.
Typical benchmarks reached include:
- 100 kbps, the minimum necessary to deliver mobile video to all consumers
- 300 kbps, for reliable, enjoyable HD mobile video experiences
- 1 Mbps, for monetisable full HD mobile video
- 2 Mbps, for HD IPTV programming for all xDSL users
- 6 Mbps, for UHD movie streaming at scale
- 10 Mbps, for scalable DTH/Cable UHD sports services.
Guido Meardi, V-Nova CEO and co-founder told EE News Europe that compared with H.264 Perseus-2 roughly doubles the number of channels from a given infrastructure at these acceptable benchmarks. Compared with HEVC it quintuples channels and would do even better than that against VP9.
Perseus is a different codec to the standardized H.264 and HEVC and the open-source VP9 but it can be used in conjunction with any of them in the Perseus-2 Plus variant. This allows users to make use of subtitling, sync-ing, transcoding, digital rights management and other features from the established codecs while taking benefit of the coding efficiency of Perseus.
The software-centric nature of Perseus has allowed V-Nova to install Perseus on deployed mobile phones and perfrom UltraHD decoding
