First 8K Live Video Broadcast
NHK, the main Japanese TV network, and also a big corporation with research departments, was recently able to successfully broadcast 8K video on the air. To simply understand what it means to broadcast video in 8K, we can think of it as transimitting video with a quality “equivalent” to that of a 33.1 megapixel camera. The feat has been possible by using orthogonal frequency-division multiplexing (OFDM) imitating the techniques used by laptops to receive Wifi signals via 802.11.
As of now, it has only been a transmission test at a 27 km (17 miles) distance but NHK is already planning to broadcast the Tokyo 2020 Olympics in 8K.
