- The problem that the new PERSEUS video compression codec solves
- PERSEUS applies massively parallel processing, like animals, for super-efficient compression
- What makes PERSEUS compression different, including the end of block-based processing
- Even if PERSEUS compression was worse, its adoption would still be inevitable

Alcatel-Lucent and Oregan to offer first Perseus IP Video solution
NTT DATA integrates V-Nova’s PERSEUS into video encoding solutions
EE and British start-up V-Nova appear to have solved the problem of streaming 4K Ultra HD video over ultra low-bandwidth connections.
ect ...
Donc l'affaire est dans le sac pour la start-up V-Nova et Perseus
Il faut bien admettre que réduire d'un facteur 3 le débit pour de la vidéo en 4K c'est indispensable, sinon il y aura des problèmes de bandes passante sur le réseau des réseaux.

Finit les blocs de carrés sur des scènes en mouvement comme la mer agitée, les scène avec les jeux de lumières, cela va être du passé avec compression/decompression video AVC et PERSEUS dès l'an 2016 :-)
“It seems counter-intuitive but when the AVC scene is breaking down, the reason you see the artifacts is because it [the codec] is compressing the data harder. It is over-compressing because it does not know what to do,” Eksten explained. “When you are over-compressed you see the blocks. PERSEUS fixes this issue and accomplishes it [the scene composition] without the usual artifacts and at less bit rate. It does not use blocks. When you put the two codecs together it is a superior result from a visual point of view.”

Merci pour ces infos redge
Je peux imaginer que pour nos voisins transalpins il y a une nécessité d'améliorer l'accès à l'IPTV aux clients qui ont des débits insuffisant pour de la HD avec du mpeg4 par exemple.
En suisse Swisscom annonce qu'environ 80% des raccordements peuvent disposer de la TV en HD, alors qu'en Italie cela doit être bien inférieur à 80%
30 à 40% de réduction pour de la HD, cela donne la possibilité de proposer la HD avec des raccordements DSL inférieur à 7 Mbits
Nos FAI suisses vont-ils aussi s'y mettre ou alors faire la fine bouche, comme c'est parfois le cas, car c'est bien connu, nous sommes meilleurs que les autres ... parait-il

Osons espérer que nos "braves" opérateurs utilisent Perseus pour l'intégrer dans les futurs box !
2eme moitié 2017, Net+ devrait probablement proposer une nouvelle box avec de la 4K, Perseus sera-t-il du voyage ?
Car généraliser la 4K avec 25 Mb/s de bande passante comme actuellement, c'est tout simplement impensable, les réseaux ne tiendront pas le choc, X milliers de clients avec chacun un flux individuel à 25 MB/s il ne faut même pas y penser ...
Avec Perseus c'est ok

PERSEUS 2 is a more efficient codec than its predecessor and one of the results is even better picture quality within crucial bandwidth thresholds that make or break the business model for new services. It enables better mobile video at 100 kbps to enable comprehensive reach, including across 2G networks, and it now supports better quality at 1Mbps for monetizable full HD video on mobile. There are picture enhancements at 2Mbps for HD on DSL and at 10Mbps, a threshold that opens the door to multichannel UHD sports on satellite and cable.
According to Fabio Murra, SVP Marketing at V-Nova, (the company behind PERSEUS), the new generation provides a step-change in performance. “We have done a lot of work to improve computational efficiency.” This results in much greater density. More density equates to lower CapEx or OpEx, whether video processing is on-premise or in the cloud.
http://v-net.tv/2017/04/06/perseus-2-provides-higher-density-more-device-support-and-can-be-used-on-top-of-hevc-and-vp9/
Thanks to improved codec efficiency and a lighter decode footprint, PERSEUS can also be used with a wider range of chipsets and browsers. Decoding is now supported in the HTML5 environment. Set-top box chips as old as nine years can process the codec. V-Nova is already supported on both Broadcom and ST SoCs. Murra says: “We want to be compatible with devices doing back as far as possible. We cannot wait for handset and television replacement cycles and we have to get the best that is possible from the device ecosystem.”

V-Nova: The strategy behind PERSEUS 2 – and why there’s still room for lots more compression efficiency
...
“We know that in today’s world, people want to stream more and more channels. We needed to lower the cost-points,” said Meardi. While PERSEUS was fast, V-Nova knew it could make PERSEUS 2 even faster, and that translated into several benefits. “The first one is very, very low cost of encoding, low processing-power utilisation, low electricity [demand], and high densities. […] Yes, it encodes Ultra HD p60 broadcast quality at 10Mbps, but the most important thing is, it costs so much less.”
The second benefit PERSEUS 2’s speed enabled was making it easier to use on all platforms, noted Meardi. In initial deployments, PERSEUS “was working very well in closed environments like an IPTV deployment or in app deployments.” But V-Nova realised that video delivery was moving to a more fragmented environment, where “HTML-5 was taking over. […] So with PERSEUS 2 we created and we are presenting at IBC, the possibility to decode PERSEUS within a browser, within all the HTML-5 ecosystem, using simple JavaScript decoding.”
Meanwhile, PERSEUS’s ability to work in two different modes, as a standalone video compression system [PERSEUS Pro] or piggy-backing on existing codecs to improve their performance [PERSEUS Plus], was expanded. Where PERSEUS Plus previously worked in tandem with H.264, at IBC the next-generation platform was shown also supplementing HEVC. “In general, PERSEUS 2 is amenable to any type of base encoding – so when AV1 becomes available, […] it will work also with AV1. It [also] works on top of VP9,” said Meardi. This means, he claimed, that for operators, “PERSEUS is actually the cheapest and simplest option to immediately achieve massive benefits – because it’s compatible with the whole eco-system, it’s a simple software upgrade and doesn’t change anything.”
Finally, V-Nova has optimised PERSEUS 2’s performance around specific operating points, to reflect the common bottlenecks in today’s video distribution networks. “We’ve understood those limits over the past two years and we optimised PERSEUS specifically for those operating points. That’s why when we say we do OTT 720p HD at 300 or 400KBps, that’s not just a number picked at random. […] If you want to do mobile video, very often the majority of people have a maximum 300, 400 or 500Kbps.” Meardi notes that even in central London in peak hours, “very often you’re below 600KBps even with 4G.”
