NHK To Demo 8K Video Transmission Over a Single TV Channel at 2014 NAB Show

Japanese public broadcaster NHK will present the latest iteration of its Super Hi-Vision system at the 2014 NAB Show, including a closed-circuit demonstration of over-the-air transmission of 8K content in a single 6 MHz UHF TV channel.

The demonstration will be available at the NAB Labs Futures Park, April 7-10 in Las Vegas. This will be the first time anywhere in the world outside Japan that wireless transmission of 8K Super Hi-Vision has been demonstrated over a single 6 MHz TV channel. NHK will also present results of a long-distance, single-channel, over-the-air 8K test broadcast recently conducted in Japan (more inforation here).

In addition, the NHK exhibit will feature a presentation theater with a 350-inch screen for viewing newly shot Super Hi-Vision content with 8K video projection and full 22.2-channel sound reproduction, including highlights from the Sochi Winter Olympic Games.

Progress in the increasing practicality of Super Hi-Vision systems will also be demonstrated, including an 8K video camera that weighs less than 4.5 lbs (2 kg), the world's first 8K-capable real-time HEVC encoder, and a display-integrated immersive sound system providing virtual representation of 22.2-channel sound for a domestic environment.

NHK also plans to show its latest developments in hybrid TV with a presentation of its "Hybridcast" system, providing interactive capabilities via a converged broadband/broadcast service, which launched last September for regular consumer service in Japan.
