 Vapour-ware or serious competition for h265, vp9, dirac and friends?

A new method of data compression could see ultra-high definition video - also known as 4K - being streamed to TVs and other devices using around 50% of the bandwidth currently needed.

V-Nova has gathered 20 large telecoms, broadcast and IT companies including Sky, Intel, and the European Broadcasting Union to back its new Perseus technology.

It could see the average home broadband speed in the UK - around 22 megabits per second (Mbps) - support three 4K streams simultaneously instead of just one.
The technique makes use of the multiple cores within processors found in today's mobile devices and smart TVs to process the picture more efficiently.

Movie streaming firm Netflix currently requests users of its 4K Ultra High Def service to have a steady 25Mbps broadband connection, with analysis of their video stream showing between 12 and 16Mbps is actually required.

V-Nova says it can deliver the same quality picture using just 7-8Mbps.

Media expert Ian Maude, from Enders Analysis, said: "This is cutting-edge technology that will be welcomed by pay TV companies, and TV manufacturers because it will help drive 4k sales.

"But there are still limiting factors to the take-up of 4K including whether networks are capable of meeting demand, having a device able to display an ultra-high definition picture, and the amount of content currently being shot in 4K.

"Ultra HD will still remain niche for some time but this technology will help."

The technology also allows HD video to be streamed to mobile phones by using a similar amount of bandwidth to that currently needed to play music.

It is hoped the new encoding technique will help social network users share video as easily as sending messages, and bring standard definition video to millions of devices in developing countries where cellular data rates make it too expensive to stream any quality of video.

The system will first be deployed in the US and several European countries this summer with UK content distributors and broadcasters introducing it before the end of this year.

The BBC's Dan Simmons took a first look at how the system works.

Some research, the company is from the UK, http://www.v-nova.com/en/index.html and allegedly "Developers of the original MPEG technology".

Why have V-Nova and PERSEUSŪ been kept a secret for so long?
We believe that tested, commercial-grade products trump presentation slides and empty claims.

There is a big difference between delivering a robust commercial-grade product in mission-critical industries and merely demonstrating a technology. PERSEUSŪ is the result of years of testing and a growing consortium of over 20 global partners.

:raise:

They are a real company since 2011 and releasing products through Hitachi and others for live streaming, here showing 30-200mbps for 4K in 2013:

She is a cat of significant gravy.
Until we see the quality of the video we won't know if it's worthwhile or not. I don't understand why the article claims it will only work in TVs though, but the video says otherwise? Most important, why does the BBC think I want auto-playing video that only starts when I've already scrolled away from it? :argh: The video is completely useless as well, they have the CEO of the company but he just describes how compression works in general.

Edit: The annoying auto-playing video does show a 4k screen displaying video with their compression technology and it looks good.

Edit 2: Their website says the video encoding works on aircraft data, which I have to assume is text. :confused: I do want to see 2 megabit/sec HD video though. Save lots of bandwidth.
