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.

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 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.

Qualcomm has introduced a mobile chip that will play back 4K video on smartphones and tablets in addition to supporting the latest 802.11ac Wi-Fi.The Snapdragon 805 chip, announced on Wednesday, could be Qualcomm’s fastest performing chip. The quad-core chip operates at a clock speed of 2.5GHz and has the latest Adreno 420 graphics engine, which can process 4K or UltraHD video at a 3840 x 2160-pixel resolution.

As consumers feast on even more video across multiple devices, the advent of Ultra HD – which has four times the picture quality of HD – will simply choke bandwidth. Sean McCarthy, of Motorola Mobility, says its future depends on a smarter, slimmer codec.
