Recently, NHK intends to enrich services for local viewers by increasing local or regional programs from the local TV stations. This attempt is not convenient for informing nationalwide urgent-news, because every station broadcasting its own program have to superimpose the information quickly and surely. The Nationalwide Urgent-news Superimposing System developed to solve this problem. This system has been built on the fundamental facilities of News Center (NC), NHK Tokyo.
