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.V-Nova says it can deliver the same quality picture using just 7-8Mbps. https://www.youtube.com/watch?v=sEce_FRlgL8 "Ultra HD will still remain niche for some time but this technology will help." 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.
