Enthusiasm for the Olympic Games are shared nationwide through public viewing. Many people are enjoying 4K / 8K programs at home Around 2025 <Image> Various full broadcasting programs via BS (LHCP) and 110E CS (LHCP) are televised. Reception environment of LHCP are well developed as well as that of RHCP.

23 2nd interim report said 23 2nd interim report of follow-up meeting on the 4K/8K roadmap (July 2015 publication) Efforts related to terrestrial broadcasting It is conceivable to consider field experiments for public viewing by terrestrial waves in urban areas in order to verify the technical possibilities and achieve more-efficient transmission based on speedy comprehensive research and development. Additionally, NHK is conducting research and development on terrestrial broadcasting systems and field experiments on 8 K terrestrial transmission. It is important to continue to provide information about these achievements.
