High definition TV developments in Japan

The present status of HDTV developments in Japan is described. In Japan the accelerated domestic penetration of HDTV has started because of the increased duration of HDTV broadcasting and the rapid reduction in the price of TV receivers. High quality standards converters have already been developed which convert HDTV signals between the 1125/60 and 1250/50 standards. There is no practical limitation for the exchange of programs produced based on the different standards.
