Super Hi-Vision

NHK of Japan started development of Super Hi-Vision technology and showed prototype in 2002. Its video resolution is far better than HDTV at 7680 x 4320 or around 16x greater. Audio portion is 22.2 as compared to only 5.1 of HDTV (typical). Because of the huge amount of data involved in this format, along came the requirement for cameras, transmission technology and display media that can handle such content. Present compression technology can reduce data stream down to 180Mbps only and there is no transmission medium yet that can accommodate such bandwidth. It will take some time before commercial deployment of this format can be implemented.
