Japanese TV networks have launched ultra-high definition 4K and 8K broadcasting. The formats feature images and audio far exceeding the levels used in conventional high definition broadcasting.
At a ceremony in Tokyo on Saturday, Communications Minister Masatoshi Ishida said he hopes Japan will play a leading role in 4K and 8K broadcasting.
NHK President Ryoichi Ueda said the broadcaster will aim to spread the service by delivering exciting experiences for viewers.
After a countdown, at exactly 10 AM, broadcasters started showing programs in 8K and 4K on specially arranged monitors.
NHK is broadcasting the new services domestically on the satellite channels BS4K and BS8K.
The formats can only be enjoyed on certain TV monitors or with external tuners.
