NHK begins 4K, 8K high-definition test broadcasting

Kyodo

Public broadcaster NHK on Monday started 4K and 8K ultra high-definition test broadcasting on its BS satellite channels, aiming to verify the technology and popularize it ahead of the 2020 Tokyo Olympics and Paralympics.

The resolution of 4K broadcasting is roughly four times as detailed as that of the currently available format, while 8K broadcasting, which is making its world debut, offers 16 times finer resolution.

Viewers cannot watch 4K and 8K broadcasting with conventional television sets or tuners. NHK will place 8K televisions at its broadcasting centers nationwide for visitors to experience.

NHK, officially known as Japan Broadcasting Corp., will offer 8K broadcasting of the opening ceremony of the Rio de Janeiro Summer Olympics as well as swimming and track and field events.

Public viewing events for 8K broadcasting are also planned in six venues including in Tokyo and Osaka.

The Ministry of Internal Affairs and Communications is planning to start 4K and 8K broadcasting by 2018 and popularize it in time for the Tokyo Games.
