1. A receiving set comprising:
- a record circuit to convert a received and detected audio signal into a signal suitable for recording;
signal compressing means to compress the output signal of the record circuit on a time axis;
a memory to store the output signal of the signal compressing means;
a reproducing circuit to reproduce the contents of the memory;
a switch for selectively providing the received and detected audio signal or the output audio signal of the reproducing circuit;
reproduction request detecting means to detect whether or not a reproduction request is given;
state switching control means to establish a reception-record state in which the switch is controlled so as to provide the received and detected signal, when the reproduction request is not given, and to establish a reception-record-reproduction state in which the switch is controlled so as to provide the output audio signal of the reproducing circuit and the received and detected audio signal is compressed and stored in the memory during reproducing operation, when the reproduction request is given; and
state reset control means to reset the state switching control means in the reception-record state upon the coincidence of the received and detected audio signal and the output audio signal of the reproducing circuit in the reception-record-reproduction state.

Abstract
A receiving set is capable of recording the sound of the broadcast received, while enabling the listener to listen to the present broadcast, and of reproducing the recorded sound when requested by the listener. A digital memory device is provided for recording the detected audio signal in compressed form on the time axis. The memory device is accessed upon request by the listener and the signal read out of the memory is processed to produce a sound.

8. A receiving set comprising:
- a record circuit to convert a received and detected audio signal into a digital signal;
signal compressing means to compress the output signal of the record circuit on a time axis;
a memory to store the output signal of the signal compressing means;
a reproducing circuit to convert a digital signal reproduced from the memory into an audio signal;
a switch to provide selectively the received and detected audio signal or the output audio signal of the reproducing circuit;
reproduction request detecting means to detect whether or not a reproduction request is given;
state switching control means to make the switch provide the received and detected audio signal and to make the memory store the received and detected signal given through the signal compressing means, when the reproduction request is not given, and to make the switch provide the audio signals reproduced sequentially by the reproducing circuit from the contents of the memory stored at predetermined addresses and to make the memory store the received and detected audio signal giventhereto through the signal compressing means, when the reproduction request is given; and
state reset control means to change the output of the switch from the output audio signal of the reproducing signal to the received and detected audio signal upon the detection of the coincidence of the recording address for storing the received and detected audio signal in the memory and the reproduction address for reproducing the audio signal of the reproducing circuit from the memory, while the output signal of the switch is the output audio signal of the reproducing circuit.
- a record circuit to convert a received and detected audio signal into a digital signal;
