Abstract

NHK has developed a new FM multiplex broadcasting system called DARC (data radio channel). DARC can provide new services such as general information, traffic information, radio paging and differential GPS data by multiplexing digital signals with existing FM stereo broadcasting signals. Data transmitted by DARC can be received correctly even when mobile, therefore, it is expected that traffic information by DARC will be broadcast in Japan. Three levels of traffic information service have been considered. For safety reasons, control data for easy operation can be thought out
