ABSTRACT:
A service information receiving device receives pay service information and year/month/day-of-month data, both multiplexed with FM broadcast radiowaves and transmitted from an FM broadcasting station. The device compares the use end date data, stored in an information storage medium which is detachable from the device, with the year/month/day-of-month data received by the device, and the device permits the display of the pay service information during the period in which these two sets of data disagree with each other, and after they have coincided with each other, inhibits the display of the pay service information.
