Soon you could be streaming 4k video over your broadband network, and full HD to your mobile devices. The new H.265 video format has been approved by the ITU as a successor to the H.264 codec standard driven by the launch of the iPad and other post-Flash mobile devices. H.265 is informally known as High Efficiency Video Coding, and compatible chips are expected to appear within 12 to 18 months. Soon, as little as 20 Mbps of bandwidth could allow 4k video streaming.
