Wear a VR helmet rotating the head, walk around, this is a virtual reality (VR) in most people's impression, and the Japanese NHK TV has a huge device to play VR video, and the experience is not needed to wear a helmet.
The alternative is an 8K resolution projector, and the image is projected on a half arc screen of a 5x3 m. The front of the screen is a two seats, and the audience watch video on this chair that will sway.
The film content is a city propaganda called Tokyo Victory, which includes all Tokyo landmarks. The seat will make an illusion that you are also getting into the ground as the view is constantly changing with the angle of view of the film.
NHK did a VR without helmet, but also made 8K a land
The entire system is completed by NHK TV and a Tokyo Technologies Wonder Vision, named Sphere 5.2. In addition to screen, projector and seat, Sphere 5.2 also has a fan and other supporting devices, let the audience feel the wind.
Simply speaking, this is a small cinema that is closer to the screen, and it is similar to some science museum or playground to play a film experience project.
This is not the first time NHK's dazzling skills on the 8K movie. On August 6th, the opening ceremony of the Olympics, NHK used 8K technology to broadcast TV in Japan, which is the world's first TV station. .
8K can reach the resolution of 7680x 4320, which is almost four times that of 4K, 16 times that of 1080p. However, this touted technology actually has no meaninglessness of the ordinary audience - 8K resolution exceeds the human eye, unless you are in front of the TV, you can see the difference between the naked eye. Even if you watch 4K household TVs under normal distances of 2-3 meters, you can't distinguish it and the difference between its 1080P TV.
And the 8K TV price on the market is expensive. The NHK Rio Olympics 8K broadcast service group only broadcasts 130 hours of competition, only 1.8% of the total broadcast duration, more like an experiment.
Sphere 5.2 is also far from the ordinary audience. You can't move this device home, but it has found some practical uses at least 8K, and there is only such a big screen to make the audience really experience the Extreme effect of 8K.
For Japan, 2020 Tokyo Olympics is a great opportunity to showcase the level of technology. Japan is also intended to sell its broadcast technology overseas to reinvigorate their leadership in the international electronic product market.
