Back in May of 2012 the NHK’s science & Technology Research Lab in Japan successfully broadcasted an 8K, 7680×4320 signal over a distance of 2.7 miles using UHF frequencies. As a proof of concept it showed that 8K TV could be successfully delivered to televisions over the air, but it lacked the distance of traditional TV broadcasts.
Less than two years later, however, using improved equipment and techniques, the NHK has successfully completed another test where its researchers broadcasted an 8K over the air signal from its offices in Hitoyoshi, Kumamoto Prefecture, in southern Japan, to a receiving station 27km away without any signal loss.
And that’s a significant milestone, because 27km is roughly the same distance achieved by current digital over the air broadcasts in Japan. So now all we need are some 8K cameras and to convince studios to start shooting all their shows in UHDTV. [NHK via PCWorld]
