4K TV broadcasts are still considered a figment of the imagination in most countries across the globe but there’s one broadcaster in Japan that’s already looking far ahead into the future. NHK, Japan’s public broadcaster, has started the world’s first regular TV satellite broadcast in amazing 8K resolution. It has launched the “Super Hi-Vision” test channel that broadcasts content in both 4K and 8K resolution.
At 7680 x 4320 pixels, 8K resolution can claim to be four times as sharp as 4K and 16 times as sharp as full HD or 1080p. It also allows for 22.2 channel audio.
4K TVs have only now started becoming popular and the prices have come down to a level that most people can afford them but 8K TVs are neither widely available nor are they cheap at this point in time.
So even if you’re in Japan and can access the Super Hi-Vision channel you won’t be able to get much use out of the 8K resolution broadcasting until you have a TV that supports such high resolution.
NHK is aware that 8K TVs are not something you would find in most homes so it’s going to set up viewing stations across Japan to enable people to experience 8K broadcasts, footage from the 2016 Olympics will just be one of the 8K content experiences that will be showcased at these viewing stations.
