Sony, fresh from revealing its 84in 4K TV, has got its brainiacs to work on compressing 4K information for easier broadcasting.
Thanks to some clever compression using the current H.264 tech, Sony has managed to broadcast 4K footage in a broadcast-friendly 50Mbps stream. That means people like the BBC could start streaming 4K without the need to upgrade physical infrastructure – meaning 4K broadcasts could come sooner than we thought.
Sony is still ploughing on with a new compression called HEVC – High Efficiency Video Coding – which should have 4K down to a 20Mbps stream soon for sending multiple signals. With EE offering fibre optic broadband and Virgin aiming to hit 200Mbps, it might be time to buy a 4K TV. Sony or LG 4K is the question.
