[1] The format was first publicly displayed at the Expo 2005 in Aichi Prefecture, Japan, whereas the first 8K live feed broadcast were tested at the 2012 Summer Olympics in London.

[5] Unlike its preceding formats, BS8K's 4320p resolution is displayed through a progressive scan standard, as opposed to the traditional 1080i HDTV that is commonly used by broadcasting systems around the world, including NHK's General TV service.

[5] To promote the launch of BS8K, NHK opened a "Super Hi-Vision Park" at an event hall in Shibuya, Tokyo from 30 November 2018 to 4 December 2018, featuring an "8K Living Room" equipped with an UHD TV and a 22-multichannel home theatre system.

[5] On 1 December 2018, the NHK Science & Technology Research Laboratories also demonstrated a public viewing of both the BS8K and the BS4K channels, which included a live feed of the Roman Forum and the Pantheon in Rome, Italy, and a presentation of the remastered version of the feature film 2001: A Space Odyssey (1968).

Some of the programs being broadcast include footage shot in 8K from Antarctica and the International Space Station, the annual Kōhaku Uta Gassen, and recorded concerts from some of the world's leading orchestras to showcase the immersive 22.2 channel sound.
