Japan just announced that in July 2014 they would begin transmission of their first ever 4K broadcast. The 4K services will be transmitted directly from Japanese satellites, then onto the broadcasters on the ground. The Japanese government is hoping the announcement will spur sales of super HD television sets, which will in turn boost sales of Japanese electronics makers.
Super HD 4K televisions have approximately four times the regular resolution of the currently sold HD TVs. Many South Korean electronic producers have begun sales on their 4K TVs along with some of Japan’s big brands such as Panasonic, Sharp and Sony.
The Ministry of Internal Affairs and Communications previously announced that the TV service would start sometime in 2016.
