NHK To Demonstrate 8K Video Transmission over a Single TV Channel at NAB Labs Futures Park

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 detailed results of a long-distance, single-channel, over-the-air 8K test broadcast recently conducted in Japan.

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.

NHK is one of 15 organizations presenting demos in this year’s NAB Labs Futures Park, a section of the NAB Show exhibition floor reserved for broadcast-related research and development projects from around the world. Other exhibitors at the 2014 NAB Labs Futures Park will present demonstrations of emerging technologies such as high frame-rate and high dynamic-range video, advanced media preservation techniques, augmented broadcasting, targeted advertising, and advances in video compression, 3D TV, emergency alerting, and more.

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
Containers have changed the mind of IT in DevOps. They enable developers to work with dev, test, stage and production environments identically. Containers provide the right abstraction for microservices and many cloud platforms have integrated them into deployment pipelines. DevOps and Containers together help companies to achieve their business goals faster and more effectively.
