NHK to Make 8K Broadcast History at NAB 2014
NHK is set to demonstrate the very first United States broadcast of 8K video signal at NAB 2014.
In our previous article we examined the difference between 4K and HD in regards to its relationship with 8K video. Recent announcements made by NHK have inspired us to examine 8K broadcasting more in-depth…
NHK is one of the world’s leaders in future video technologies. They have been on the cutting edge of creating better viewing experiences in regards to video resolution. For example, they were testing HD signal at the 1984 Olympic Games, which was over 15 years before consumers were even buying HD TV’s.
Fast forward to 2014 and NHK is the leading advocate for 8K broadcasting. Since 2012 they have been testing 8K video signal from their home in Japan. In January of 2014, NHK successfully transmitted a long distance broadcast of 8K signal with 22.2 surround sound from 27 kilometers (16.7 miles) away. The signal transfer happened on a single 6 MHz TV channel which shows it is possible to broadcast 8K signal using available airwaves.

This broadcast featured a data signal of 24 Gbits a second and has the ability to broadcast at 120 frames per second. Broadcasting the signal was possible due to Orthogonal Frequency-Division Multiplexing (OFDM), a data encoding method used in wi-fi signals. They also use multiple input/output data signals that breaks the signal up into 6 smaller parts. In short, the signal is impressive and definitely futuristic.
8K at NAB 2014
NHK has recently announced that they plan to demonstrate 8K broadcasting at the National Association of Broadcasters (NAB) show in April 2014.
