NTT and NHK announced that they succeeded in the international relay of a super high-definition video that is 16 times as fine as a high-definition video. Embedded with their original data compression technology, the experiment transmitted a video for a distance of 80,000 km using the next-generation high-speed line of optical fiber. The transmission delay was 0.3 second that is a quarter of the time required by the satellite connection. The new technology is expected to allow for public viewing to enjoy videos of sports events transmitted from abroad in a large screen. In the experiment, a video filmed in NHK’s Science and Technology Research Laboratories in Tokyo was transmitted to BBC in London via the U.S., and subsequently it was transmitted back to NTT’s International Sharing Laboratory Group in Tokyo. The new data compression method successfully reduced the data capacity and strengthened the security function to protect data. Super high-definition can reproduce 33 million pixels, 16 times as many pixels as the number of pixels transmittable by high-definition. The next-generation high-speed line is being constructed for universities and laboratories in Japan.
