As part of the launch day of its world’s-first regular 8KTV service, BS8K, Japan’s national TV group NHK broadcasted live images from the Vatican in 8K via the EUTELSAT 12 West B satellite.

NHK Eutelsat 3dec2018BS8K will offer offers twelve hours of 8K Ultra HD programming each day and launched on 1 December. Itwill feature 8K Ultra HD footage of major cultural and sporting events, museums and natural landscapes, providing viewers with a fully immersive experience and will allow for further experimentation with 8K prior to the large-scale deployment of the format for the Tokyo Olympics and Paralympics games in 2020.

NHK promises that its programmes will provide viewers with a sense of full immersion in each scene, imparting the feeling of presence in the stadium or concert hall. Core content will also include TV dramas and nature programmes and, in cooperation with NASA, scenes of the Earth shot from the International Space Station (ISS). Art broadcasts will feature masterpieces of the Louvre and the works of Katsushika Hokusai.

BS8K  service began with the airing of show Stanley Kubrick’s legendary film 2001: A Space Odyssey scanned at 8K resolution by studio Warner Bros. The following day, Eutelsat transmitted the live broadcast to Tokyo from the Vatican via its craft with a mobile uplink provided by M-three Satcom.

To achieve what is regarded as a technologically challenging feat, NHK relied on DVB-S2X modulation, in 16APSK, and HEVC encoding. The images — 7680 pixels over 4320 lines, resulting in 33.3 million pixels per image — were shot at 60 frames per second in BT2020 colour space, with 10 bits of colour depth, the equivalent of a billion colours, and high dynamic range HLG (hybrid log gamma), combined with 22.2 channel audio.

“Eutelsat has been a pioneer in delivering HD and Ultra HD formats since their inception, and this broadcast confirms satellite’s unique position as one of the vital technologies capable of broadcasting 8K signals,” remarked Gerry O’Sullivan, executive vice president, global TV and video of Eutelsat. "We look forward to working hand in hand with customers such as NHK as they continue to raise the bar higher for the broadcasting industry, to deliver the best possible video experience to viewers.”
