V-Nova streaming tech produces 4K compression ‘worth watching’

1 April 2015 Last updated at 00:22 BST

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.

We need Immersive TV, not just 4K | VideoNet

There was a reminder at the recent SES Ultra HD Conference that some of the new technologies that are being investigated for UHD can also be applied to HDTV with potentially striking effect. Dr Giles Wilson, Head of TV Compression at Ericsson pointed out that if you take 10-bit, high dynamic range (HDR) and 60Hz (frame rate) and apply these to HD “it still provides a massive leap forward in the viewing experience…and there are circumstances where there is not enough bandwidth to offer UHD and you might want better HD.”

Ultra HD is the real thing; get ready for disruption | Videonet

Ultra HD is the real thing; get ready for disruption | Videonet

Ultra HD is not another 3DTV, set to grab the headlines and then fade away, but is the next big consumer-facing development in television and one that will prompt a new arms race in the Pay TV industry and new infrastructure investments. That was the conclusion from a Videonet webcast last week that looked at what we learned from International CES 2014. On a panel featuring experts from Strategy Analytics, MTM London and Genovation Capital, it was argued that the early efforts of OTT service providers like Netflix to get UHD content in front of consumers will not give them any long-term advantage over the Pay TV industry.
