PROBLEM TO BE SOLVED: To improve the channel efficiency by limiting the number of reception enable times with a memory card purchased in advance and set to a count section so as to use a channel thereby eliminating the need for controlling the receiver from a transmitter side. SOLUTION: A decoder 3 demodulates a reception signal to output a service information signal when a call number to receive the service information is detected. The receiver is provided with a time designation section 5 designating in advance a time when reception of the service information is made available and a time compactor section 6 comparing the time when the service information is received with a designation time of the time designation section 5 to provide the output of a coincidence signal when the are coincident with each other. Then a counter section 7 counts down it from a preset number of times at each output of the coincidence signal, and when any residual number of times is in existence in the counter section 7, the service information signal is tentatively stored in a memory section 8. Then a notice section 9 reads the service information in the memory section 8 by a prescribed operation and notifies it. |
