Do you think that 4K resolution is still far from the Brazilian reality? The first televisions with the technology start to appear here, but it is already beginning to talk about television broadcasts in 8K. The technology can already be used at the 2016 Olympics by the Japanese state broadcaster NHK.
In Japan, the NHK itself leads the development of UHDTV, which allows reproduction of images up to 7,680 x 4,320 pixels. By then, transmissions in 8K should start only in 2016 via satellite and in 2020 by terrestrial.
With this resolution, the image quality would be 16 times better than the Full HD standard, which is currently the most widespread in today’s high definition televisions. But the image is not the only advantage.
According to the director of entertainment engineering at Globo, Raymundo Barros,in an interview Folha de S. Paulo, the intention of the technology is to create more immersion and, for this, audio also needs to accompany the quality of images. 8K videos are captured on 22.2 channels, compared to just 5.1 today.
In addition, the trend is that, with the future popularity of 8K, larger and larger televisions will be created for smaller and smaller spaces. The publication points out that currently the recommended distance to watch a Full HD TV is 3 times the height of the TV, while the 8K TV will be only 0.75 times the height of the screen.
The resolution was already tested in Brazil, when a Japanese team landed in national territory to record images of landscapes and Carnival.
It is worth remembering that Brazil still does not have any type of transmission even in 4K and many people still watch television by analogue signal. Globo, however, already captures some images for its 8K novels. Each minute of uncompressed video takes up 200 GB of storage.
