TOKYO—School might be out here in the U.S., but Japanese broadcaster NHK is getting ready to test both 4K and 8K high-definition broadcasts on its BS satellite channels, according to a report from The Japan Times. The goal of these tests is to reportedly verify and popularize the technology ahead of the 2020 Summer Olympics and Paralympics, which will take place in Tokyo.
Currently, viewers are not able to watch 4K or 8K broadcasting with conventional TV sets or tuners. To offer a preview, NHK says it will place 8K TVs at its broadcasting centers across Japan for visitors. The broadcaster will offer 8K coverage of the opening ceremony of the 2016 Summer Olympics in Rio de Janeiro, as well as swimming and track events. Public viewing events of 8K are also being planned at six venues in Tokyo and Osaka.
Japan’s Ministry of Internal Affairs plans to start broadcasting in 4K and 8K in 2018.
