Development of 8K resolution

NHK first demonstrated this technology at Aichi Expo in 2005, and in June 2005, 1 1 broadcasted it to UHDTV 260 kilometers away through optical fiber network and DWDM transmission technology. At the end of 2006, NHK Red and White Song Club transmitted UHDTV images from Tokyo to Osaka, more than 500 kilometers away, and broadcast them live on a 450-inch (1 1.4m) screen. Uncompressed 20-minute UHDTV programs will occupy 4TB of storage space.

20 12 On August 23rd, -ITU, a subsidiary of the United Nations, just adopted the resolution of 7680x4320 recommended by NHK TV in Japan as the international standard of 8K Ultra HD -SHV, but the recognition of this standard does not mean its mass production.

SHV, as an "ultra-high-definition video system" that surpasses the current digital TV, was developed by NHK from 1995. During the 20 12 London Olympic Games, NHK released SHV in nine places around the world, including Britain, the United States and Japan (Shibuya, Akihabara and Fukushima). In Japan, NHK plans to start a pilot broadcast in 2020.

On May 3, 2003, NHK demonstrated the world's first real-time hardware encoder for 8K ultra-high definition video in H.265/HEVC format jointly developed with mitsubishi electric. In June, NHK once again demonstrated the front-end equipment specially prepared for this encoder-the world's first portable 8K ultra HD camera.

According to the plan, NHK will start broadcasting 8K TV programs to Japanese users on 20 16, and strive to make persistent efforts with mitsubishi electric to raise the refresh rate of H.265 encoder to 120 frames, so that it can compile 3D video signals.

The 32nd Summer Olympic Games will be held in JD.COM in 2020. According to foreign news, Japan is preparing to broadcast the Olympic Games with 8K technology in 2020. At this point, 8K has a clear timetable to enter our lives.

IHS predicts that the global shipment of 8K ultra-high definition (7680 × 4320) TVs will increase from 2700 in 20 15 to 201000. Most shipments of 8K TVs will focus on 65-inch TVs. It is estimated that by 20 19, this size will account for 80% of the total 8K TV shipments.
