4K Compression

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

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.
