Abstract

A service information receiving apparatus for receiving pay service information and date data which is multiplexed on FM broadcast waves transmitted from an FM broadcasting station, wherein use end day data calculated on the basis of valid term relative value data stored in a detachable IC card installed in the service information receiving apparatus and the received date data is acquired and stored, and the stored use end date data and received date data are compared. The display of pay service information is permitted while both data do not coincide, and the display of pay service information is prohibited after both data have coincided.

Claims

1. A display information receiving apparatus comprising:

a receiver for receiving display information transmitted from a display information transmitting station;

a display for displaying the display information received by said receiver;

a connector to which a storing medium for storing condition information may be detachably connected, said condition information indicating a condition for permitting said display to display said display information;

a memory into which the condition information is written from said storing medium when said storing medium is connected to said connector;

display control means for permitting/prohibiting display of the display information by said display based on the condition information stored in said memory; and

memory control means for prohibiting writing of the condition information into said memory during a period of time when the display of the display information is permitted by said display control means.

2. A display information receiving apparatus according to claim 1, wherein the display information is multiplexed on FM radio broadcast waves and transmitted therewith, and said receiver comprises an FM radio broadcast wave receiver and a decoder for decoding said multiplexed display information.

3. A display information receiving apparatus according to claim 1, wherein said condition information comprises time limit information showing a permissible time limit of display of the display information by said display.

4. A display information receiving apparatus according to claim 1, further comprising informing means for informing a user of an occurrence of a prohibition of receipt and storage of the condition information by said memory from said storing medium.

5. A display information receiving apparatus according to claim 1, further comprising:

instructing means for instructing the condition information stored in said storing medium to be written into said memory, said memory receiving and storing the condition information from said storing medium responsive to an instruction from said instructing means; and

an informing means for informing a user that the condition information is being written into said memory when said instructing means instructs the condition information stored in said storing medium to be written into said memory.

6. A display information receiving apparatus comprising:

a receiver for receiving display information transmitted from a display information transmitting station;

a display for displaying the display information received by said receiver;

a connector to which a storing medium for storing condition information may be detachably connected, said condition information indicating a condition for permitting said display to display said display information;

dividing means for dividing the condition information;

a memory for storing the condition information divided by said dividing means; and

display control means for permitting/prohibiting display of the display information by said display based on the condition information stored in said memory.

7. A display information receiving apparatus according to claim 6, wherein the display information is multiplexed on FM radio broadcast waves and transmitted therewith, and said receiver comprises an FM radio broadcast wave receiver and a decoder for decoding said multiplexed display information.

8. A display information receiving apparatus according to claim 6, wherein the condition information comprises time limit information showing a permissible time limit of display of the display information by said display.

9. A display information receiving apparatus comprising:
