NHK's SHV demo offers four times the res of Full HD

At the CommunicAsia technology expo today, Japanese national TV broadcaster NHK showed a projection system capable of 77680x4320 resolution, otherwise known as Super Hi-Vision (SHV) and exactly four times higher than 1920x1080 (Full HD) resolution. In contrast, 16 HDTVs at Full HD resolution would have to be stacked together to create one image equivalent to the Super Hi-Vision technology developed by NHK.

The demonstration took place in Singapore on a screen measuring nearly 300 inches diagonally across. NHK used two LCOS projectors, each rated at 8000 lumens, and a 33-megapixel sensor. The ultra high-definition screen was displaying video images NHK recorded with an 8K studio camera it developed in-house. To complement the demo screen, NHK used a 22.2 channel sound system.

It was the first time the technology was unveiled outside of Japan in a demonstration to the general public. Making the system small enough for public consumption is still between 5 and 10 years away, according to an NHK engineer. NHK began work on SHV in 2002, and believes it will succeed HDTV technology.
