8K Live Television Coverage of Global Sports Events in Brazil

Whilst for most observers the next generation of Ultra-High Definition (UHD) television is generally thought to use the display resolution of 3840H x 2160V, usually known as 4K, the Japan Broadcasting Corporation (NHK) has already been demonstrating use of their Super-Hi Vision (SHV) media, using the four times higher display resolution of 7680H x 4320V, usually referred to as 8K. These demonstrations to show the benefits of SHV have included the visualisation of cultural and scientific content from several countries, as well as globally known sporting events such as the Summer Olympic Games of London in 2012 and the FIFA World Cup of Brazil in 2014. In these latter two cases, NHK captured and edited audio and video content and transmitted the resulting SHV media for visualization at public viewing sites both in the host country and in Japan. This transmission was carried out through a collaboration with the academic research networks in and between intermediate countries. In 2012, this meant the use of Janet and GEANT to reach Internet2 in the US, and then on to Japan by means of the Japanese research networks, GEMnet and SCInet. In 2014, the Brazilian (RNP) and Latin American (RedCLARA) networks were used to reach Internet2. In the latter case, the total distance to Japan was greater, around 23,000 km end-to-end, more than half the circumference of the Earth. Perhaps the major difference between the experiences in 2012 and 2014 was that, in the latter case, the whole system functioned in real time, with the public viewing sites showing live coverage of the football games from Brazil. In all, nine football matches were televised in 8K media over a period of one month, including the final. The presentation will describe the audio and video technologies used in 2014, as well as the extensive preparations for efficient and effectively lossless media transmission over the intermediate networks.
